Product Description: This is an imported product, and the price is subject to changes in exchange rates. For detailed pricing, please contact customer service. I. Product Introduction: To monitor ground safety, a proven friction and wear testing machine is needed for detection. There have been many types and designs of slip resistance testers or static friction coefficient testers in the past, but many of them are bulky. The imported static friction coefficient tester from the United States is used to quickly measure the static friction coefficient of surfaces such as tiles and stone floors to determine whether the ground or walkway is safe. It is highly useful for evaluating the slip resistance of surfaces. It is a recognized testing sensor material. II. Operating Steps: Before operation, complete all preparations and clean the sensor thoroughly. Gently place the slip tester flat to prepare for formal testing. Connect the nylon thread chain to the end shaft of the instrument. Use two fingers to pull the thread, keeping the rest of the hand perpendicular to the hook, and ensure the thread is taut. Hook the loop of the thread with the index finger, curl the index finger to pull the slip tester, and then read the data displayed by the slip tester. Press the reset button twice and repeat the above testing method in four vertical directions until a safe value is sampled and recorded. Any abnormal, high, or low value should be discarded, and another value should be measured. The Underwriters Laboratories (UL) and the American Society for Testing and Materials jointly adopt a static friction coefficient of 0.50 or above as the recognized standard for providing a safe surface.III. Precautions: Before and after each use, regularly clean the sensor by sanding with sandpaper and brushing (cyclic testing) to prevent the accumulation of dust from the measurement surface during each measurement.IV. Accessories Introduction: Digital slip tester carrying case User manual  Sensor, cleaning brush, safety log Sensor pads (3 sets), accessory storage box Synthetic rubber sensors (5 sets), calibration chain Thread chain glue Decimal conversion table  400# sandpaper Weight: 3.35 kg Recommended to use a 9V lithium battery. V.

Product Description: Anti-Islanding EffectThe phenomenon where a photovoltaic power station continues to supply power to a section of the grid that has lost voltage after the grid fails is referred to as islanding. Islanding is categorized into unplanned islanding and planned islanding. The occurrence of unplanned islanding may endanger the lives of line maintenance personnel and users, disrupt the normal reclosing of the grid, and cause the frequency and voltage within the island to become uncontrolled.According to the "Technical Regulations for the Integration of Photovoltaic Power Stations into the Grid" by the State Grid Corporation, unplanned islanding is prohibited in photovoltaic power stations. Photovoltaic power stations must possess the capability to rapidly detect islanding and immediately disconnect from the grid. Their anti-islanding protection must be coordinated with the line protection on the grid side.Anti-islanding protection for photovoltaic power stations must include both active and passive methods, with at least one primary active and one primary passive anti-islanding protection mechanism implemented.If a fault causes the public connection point to disconnect from the regional grid, and the output of the photovoltaic power station exactly matches the load at the public connection point, unplanned islanding occurs.Within the island, parameters such as voltage, frequency, and phase change very little. Due to the limitations of protection mechanisms, inverters may struggle to detect the islanding phenomenon and disconnect promptly. However, since the output of photovoltaic power stations is unstable and the load is highly variable, the balance between output and load within the island will not be maintained for long. According to GB/T 19939-2005 "Technical Requirements for Grid-Connected Photovoltaic Systems," when the grid loses voltage, anti-islanding protection should act within 2 seconds to disconnect the photovoltaic system from the grid. The anti-islanding protection of the inverters planned for use in the photovoltaic power station can act within 2 seconds, disconnecting the photovoltaic system from the grid, thereby meeting the requirements of relevant national standards.Mangzhong Construction is an integrated "design + product + service" supplier based on technological research and development, supported by design optimization, system integration, and intelligent operation and maintenance services.

Product Description: Sewage treatment accessories, 304 equal-thickness auger spiral blades with shaft, left-hand and right-hand rotation. When materials are fed into the fixed trough, due to gravity and friction between the materials and the trough, the materials accumulated at the bottom do not rotate with the spiral body. Instead, they are pushed forward by the rotating spiral blades, similar to a non-rotating nut moving along a rotating screw, achieving the purpose of conveying materials. This machine facilitates multi-point loading and unloading, and can simultaneously complete mixing, stirring, or cooling functions during transportation. It is sensitive to overload and prone to clogging; it causes some crushing and wear to materials. The horizontal screw conveyor has a simple structure, making it easy to install, maintain, and troubleshoot. It is suitable for continuous and uniform conveying of loose materials horizontally or with a slight inclination (20º or less). The operating environment temperature ranges from -20 to +40℃, and the material temperature ranges from -20 to +80℃. Its rotational speed is relatively lower compared to vertical conveyors, mainly used for horizontal or small-angle material conveying, with a conveying distance generally not exceeding 70 meters.The rotational speed of the vertical screw conveyor's spiral body is higher than that of ordinary screw conveyors. The fed materials, under centrifugal force, generate friction with the casing. This friction prevents the materials from rotating with the spiral blades and overcomes the gravity of material descent, thereby achieving vertical material conveying. This machine has a small conveying capacity, limited conveying height, high rotational speed, and high energy consumption. It is particularly suitable for conveying large items. Spiral conveyors are categorized based on the direction of material displacement into horizontal screw conveyors and vertical screw conveyors. Those with conveying chains made of high-strength plastic are also known as food spiral conveyors or spiral elevators, mainly suitable for conveying large items such as cartons, turnover boxes, and bottled water. Depending on the characteristics of the materials and structural requirements, spiral conveyors include horizontal screw conveyors, vertical screw conveyors, flexible screw conveyors, and spiral tube (roller conveyor) conveyors.

Product Description: Decreased accuracy of the welding platform? Detailed explanation of the 3-step technique for repairing the scraped surface of cast iron platesThe welding platform is an indispensable reference equipment in welding operations, and the accuracy of its scraped surface directly affects the quality of welded workpieces. However, during long-term use, due to frequent placement of workpieces, spatter from welding sparks, and external collisions, the scraped surface of the welding platform is prone to wear, scratches, and other issues, leading to a decline in accuracy. Once the accuracy falls below the standard, it may cause dimensional deviations in welded workpieces and inaccuracies in welding positions. Don’t worry, below we will provide a detailed introduction to the 3-step technique for repairing the scraped surface of cast iron plates, helping to restore the accuracy of the welding platform.Step 1: Surface Cleaning and Damage AssessmentThe first step in the repair work is to clean and assess the damage to the scraped surface of the welding platform. First, use a brush or compressed air to remove dust, iron chips, and other debris from the platform surface. Then, wipe the surface with a cloth soaked in alcohol or a cleaning agent to remove oil stains and dirt, ensuring the surface is clean and free of impurities.Next, carefully inspect the damage to the scraped surface. Observe whether there are scratches, pits, worn areas, etc., and use precision measuring tools (such as dial indicators and straightedges) to measure the depth and extent of the worn areas to determine the severity of the damage. For minor scratches and wear, proceed directly to the subsequent steps. For deeper pits or large areas of wear, filling treatment may be required first.Step 2: Grinding Treatment of the Scraped SurfaceBased on the damage assessment results, perform grinding treatment on the scraped surface. For surfaces with minor damage, use grinding paste and grinding tools for manual grinding. Select a grinding paste that matches the material of the platform (such as chromium oxide grinding paste), apply it evenly to the scraped surface, and then use a flat grinding tool (such as a cast iron grinding plate) to grind in a figure-eight or straight reciprocating motion. During the grinding process, control the grinding force and speed to avoid over-grinding and causing new damage.For areas with deeper scratches or pits, start with an oilstone for rough grinding to level the protruding parts, then use fine grinding paste for precision grinding to gradually restore the surface to flatness. Throughout the grinding process, continuously check the accuracy of the ground surface with a straightedge and feeler gauge to ensure the flatness of the ground surface meets the requirements.Step 3: Precision Inspection and Fine-TuningAfter grinding is completed, the scraped surface of the welding platform needs to undergo precision inspection. Use measuring tools such as levels and dial indicators to test the flatness, straightness, and other indicators of the platform according to relevant accuracy standards. Compare the test results with the platform’s rated accuracy. If they do not meet the requirements, fine-tuning is necessary.During fine-tuning, perform precise grinding on areas where the accuracy exceeds the tolerance until all accuracy indicators of the platform meet the specified standards. Finally, clean the platform surface again to remove impurities generated during the grinding process, and then apply a layer of anti-rust oil to prevent surface rust.A decrease in the accuracy of the welding platform is not a cause for alarm. Through the above 3-step technique—surface cleaning and damage assessment, grinding treatment of the scraped surface, and precision inspection and fine-tuning—the scraped surface of the cast iron plate can be repaired, restoring the platform’s accuracy. During the repair process, be patient and meticulous, strictly following operational standards to ensure the effectiveness of the repair. Regular maintenance of the welding platform can extend its service life and ensure the quality of welding operations. more>

It can reduce inflammation, swelling, and inhibit secretion. Used for boils, psoriasis, eczema, cervicitis, vaginitis, lymphadenitis, thrombophlebitis, chronic ulcers, chronic dermatitis, radiation dermatitis, otitis externa, etc.Ichthammol forms resinous masses when exposed to acids and releases ammonia when combined with alkaline substances. Therefore, it should not be mixed with acids, alkalis, alkaloids, or iron salts. It tends to expand and carbonize when exposed to high temperatures, which should be considered during preparation.Classification: Western Medicine Dermatology Dermatological MedicationQuality Standards and Functions of Pharmaceutical Grade AspirinAspirin, also known as acetylsalicylic acid, is a widely used non-steroidal anti-inflammatory drug (NSAID) commonly employed to relieve mild to moderate pain, reduce inflammation, and lower fever. As a common medication, the quality standards of pharmaceutical grade aspirin are established by regulations such as pharmacopoeias and Good Manufacturing Practices (GMP) to ensure its safety and efficacy in drug production.Quality Standards of Pharmaceutical Grade AspirinThe quality standards of pharmaceutical grade aspirin are typically based on the Pharmacopoeia and international standards. Its quality requirements involve multiple aspects, including appearance, content, impurities, dissolution rate, microbial limits, etc. Below are the key points of common quality standards for pharmaceutical grade aspirin:1. Appearance and Characteristics- Aspirin should be a white or almost white crystalline powder with a characteristic odor. It should be free of foreign matter and obvious contamination.2. Content Determination- The content of aspirin is usually required to be between 99% and 101% (on a dried basis). Content determination is generally performed using high-performance liquid chromatography (HPLC) or ultraviolet spectrophotometry.3. Moisture Content- The moisture content of pharmaceutical grade aspirin should be less than 0.5%. Excessive moisture may lead to degradation of aspirin, affecting its stability.4. Acidity (Calculated as Salicylic Acid)- The acidity of aspirin should comply with regulations, typically controlled to not exceed 0.2% (calculated as salicylic acid). High acidity may indicate hydrolysis of aspirin during storage.5. Impurities- The content of harmful impurities in aspirin should be controlled. For example, the content of the hydrolysis product salicylic acid should not exceed 0.5%. Additionally, the presence of other potentially toxic impurities should be tested.6. Dissolution Rate- The dissolution rate of pharmaceutical grade aspirin is an important indicator for evaluating its absorption rate and efficiency in the body. The Pharmacopoeia specifies the dissolution requirements for aspirin, typically requiring at least 80% of the active ingredient to dissolve within a specified time.7. Microbial Limits- The microbial content of pharmaceutical grade aspirin should comply with Pharmacopoeia requirements. The total microbial count should generally not exceed 100 CFU/g, and pathogenic microorganisms such as E. coli, Staphylococcus aureus, and Salmonella should not be detected.8. Heavy Metals- The heavy metal content of pharmaceutical grade aspirin must meet relevant standards, typically requiring total heavy metals not to exceed 10 ppm (parts per million). This ensures safety and avoids potential health risks from harmful heavy metals.9. Packaging and Storage Requirements- Pharmaceutical grade aspirin should be stored in a dry, cool, and well-ventilated place, avoiding direct sunlight. Packaging must be moisture-proof and contamination-resistant, using tightly sealed containers to ensure the product does not deteriorate during transportation and storage due to external factors.Pharmaceutical Grade Ichthammol Medical Grade Ichthammol Complies with Pharmacopoeia Standards Sample Pack 500g per Bottle Dermatological MedicationMain Products of the Company:Ethylparaben (Pharmaceutical Grade, Excipient) 《Chinese Pharmacopoeia》Stearyl Alcohol (Pharmaceutical Grade, Excipient) 《Chinese Pharmacopoeia》Salicylic Acid (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Sodium Carboxymethyl Cellulose (Pharmaceutical Grade, Excipient) 《Chinese Pharmacopoeia》Sodium Bicarbonate (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Econazole Nitrate (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》(Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Magnesium Oxide (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Stearic Acid (Pharmaceutical Grade, Excipient) 《Chinese Pharmacopoeia》Magnesium Stearate (Pharmaceutical Grade, Excipient) 《Chinese Pharmacopoeia》Camphor (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Sodium Lactate Solution (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Metronidazole (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Steviosin (Stevioside) (Pharmaceutical Grade, Excipient) 《Chinese Pharmacopoeia》Ammonium Chloride (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Clobetasol Propionate (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Dexamethasone Acetate (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Mafenide Acetate (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Potassium Citrate (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Silver Sulfadiazine (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Allantoin (Pharmaceutical Grade, Raw Material) Ministry of Health Drug StandardsLight Liquid Paraffin (Pharmaceutical Grade, Excipient) 《Chinese Pharmacopoeia》Diphenhydramine (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Castor Oil (Pharmaceutical Grade, Excipient) 《Chinese Pharmacopoeia》Insect Wax (Pharmaceutical Grade, Excipient) 《Chinese Pharmacopoeia》Licorice Extract (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Sulfadiazine (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Sodium Thiosulfate (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Magnesium (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Gelatin (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》Glucose (Pharmaceutical Grade, Raw Material) 《Chinese Pharmacopoeia》 more>

Product Description: I. Basic KnowledgeChina's CNAS uniformly manages the accreditation of certification bodies and laboratories, and has also integrated into the International Accreditation Mutual Recognition System (IAF). The UK's UKAS is a highly authoritative accreditation body within the Commonwealth and even globally, with its crown symbol carrying immense prestige. Additionally, the International Accreditation Forum (IAF) aims to harmonize certification systems across countries, ensuring that certification certificates are recognized in international trade. Other influential accreditation bodies include the United States' ANAB and France's COFRAC.II. What Makes Certificates with Accreditation Marks "Impressive"?1. Proof of Competence: This indicates that the certification body has the technical capability to conduct certification and other services in accordance with relevant standards, reflecting a high level of professionalism.2. International Mutual Recognition: Certificates are recognized by accreditation bodies in countries and regions that have signed mutual recognition agreements, making them highly valuable in international trade and other scenarios.3. Opportunities for Exchange: Certification bodies gain opportunities to participate in international cooperation and exchange, accessing cutting-edge ideas and technologies.4. Use of the Mark: Organizations can use the accreditation mark within the scope of accreditation to enhance their corporate image and credibility.5. Authority Listing: Accredited bodies are listed in the directory of approved accreditation bodies, increasing their visibility and trustworthiness.III. Why Do Some Certificates Not Carry the Mark?1. Unaccredited Programs: If a certification program has not been accredited by bodies like CNAS, it cannot carry the mark.2. Standard Updates: For example, after the release of the new ISO 45001:2018 standard, if national standards and CNAS accreditation have not yet been updated, certificates issued under the new standard during that period will not carry the CNAS mark.3. Industry Specifics: Certifications such as commodity after-sales service certification and intellectual property management system certification currently lack accreditation standards. Certificates issued by approved bodies are valid but cannot carry the mark.For any inquiries or business consultations, please call Ms. Huang at 15513049001.

Company: 深圳市宝安区松岗开创铜铝材料厂

Product Description: Brass plate is a widely used leaded brass with good mechanical properties and excellent machinability. It can withstand both cold and hot pressure processing, making it suitable for various structural parts in machining and stamping, such as gaskets and bushings. Tin brass plate offers high corrosion resistance and good mechanical properties, with excellent pressure processability in both cold and hot states. It is used for corrosion-resistant parts on ships and components and conduits in contact with media like steam and oil.CharacteristicsBrass is an alloy of copper and zinc. Simple brass is a binary alloy of copper and zinc, known as simple brass or common brass. Varying the zinc content in brass alters its mechanical properties. Higher zinc content in brass increases its strength but slightly reduces plasticity. Industrially used brass contains no more than 45% zinc, as higher zinc content leads to brittleness and deteriorates alloy performance. To enhance specific properties, other alloying elements are added to binary brass, resulting in special brass. Common alloying elements include silicon, aluminum, tin, lead, manganese, iron, and nickel. Adding aluminum to brass improves yield strength and corrosion resistance while slightly reducing plasticity. Brass with less than 4% aluminum exhibits good comprehensive properties in processing and casting. Adding 1% tin to brass significantly enhances its resistance to seawater and marine atmospheric corrosion, hence the term "naval brass." Tin also improves the machinability of brass. The primary purpose of adding lead to brass is to enhance machinability and wear resistance, with little effect on strength. Manganese brass offers good mechanical properties, thermal stability, and corrosion resistance. Adding aluminum to manganese brass further improves its properties, resulting in castings with a smooth surface. Brass can be categorized into cast and pressure-processed products.H62 brass plate is primarily an alloy of copper and zinc with a wide range of applications. Its properties depend on the ratio of copper to zinc. H62 brass plate with over 63% copper can be cold-worked, annealed, and is ductile. Alloys with less copper and more zinc require hot working and exhibit higher strength. more>
