Product Description: Air Shower: Air showers are divided into manual air showers and fully automatic air showers. The conventional size for manual ones is 1000*1400*2150mm, while the conventional size for fully automatic ones is 1000*1700*2200mm. 1. Material: SUS304 stainless steel, with a 304 embossed anti-slip plate at the bottom.2. Visible 3C certified safety tempered glass, 5mm thick, fixed with aluminum pressure strips and silicone-free sealant.3. Nozzles: 20 nozzles per meter, multi-angle embedded adjustable mirror-polished stainless steel nozzles, with a face wind speed of 22~25m/s, meeting industry standards. Air is blown from both sides and the top, totaling three sides, ensuring excellent air shower effects. The inner blowing height ranges between 650~1500(mm). The return air position is on the inner side, between 70~450(mm) from the bottom. The air shower operates on an internal circulation system: air generated by the high-pressure centrifugal fan in the fan box enters the air plenum, is filtered through a high-efficiency filter, and forms high-pressure airflow through stainless steel nozzles, blowing into the air shower channel. The negative pressure created by the rotation of the high-pressure centrifugal fan's impeller then draws the air from the air shower channel back into the fan box through the return air vent.4. Filters: The air shower is equipped with 4 sets of partitioned high-efficiency filters with a filtration efficiency of H13 (MPPS). The filter size is 570*375*50, ensuring uniform return air.5. Fan configuration: Equipped with specialized air shower fans, low-noise high-airflow centrifugal fans, with two 0.75KW high-pressure centrifugal fans per meter, ensuring effective blowing. Parameters of the centrifugal fan are as follows: flow rate: 2550m³/h, total pressure: 1150Pa, noise ≤78dB, speed: 2840r/min, voltage: 380V, frequency: 50Hz. The voltage is 380V, and the total power is 4.5KW.6. Safety: Automatic doors come with anti-pinch devices; in case of sudden power failure while personnel are inside the air shower, the inner and outer doors can be manually opened for safe exit.7. Uses high-quality Opple LED ultra-thin embedded downlights, ceiling-mounted, with delayed lighting function. The lights turn on when the door opens and delay turning off for 60 seconds after the air shower completes.8. Circuit control: The air shower control panel and control circuit are designed and developed in-house, featuring advanced high-tech integrated circuit control with photoelectric sensors. The text display shows internal blowing, lighting display, and time adjustment buttons. The air shower time is adjustable from 0 to 99 seconds. An LED display shows the door status, fan activation status, and air shower time. The dual-door indicator system uses advanced integrated circuits for sensor-activated automatic blowing. When a person enters the air shower, it automatically senses and initiates blowing (entering from the exit does not trigger blowing, making the program more advanced and intelligent). It includes two blowing modes: intercept and direct, which can be manually switched on the control panel, and features an emergency stop function. more>

Product Description: A flameless explosion venting device is a safety apparatus designed to protect equipment and personnel by automatically shutting down equipment or pipelines in the event of an explosion or fire, preventing the spread of flames or expansion of the explosion. Its working principle involves detecting changes in gas pressure and temperature inside pipelines or equipment to determine the risk of explosion or fire. If a hazard is confirmed, the device immediately shuts down the equipment or pipeline while releasing pressure to safeguard both equipment and personnel.Brief Introduction of Flameless Explosion Venting Device for Dust Collector Venting Port in Brewery WorkshopBrief Introduction:1. It consists of two parts: an explosion venting panel and a flame quenching module;2. Suitable for flameless venting of dust explosions in indoor equipment, with high venting efficiency and cost-effectiveness;3. Effectively prevents flames and heat, providing a safe environment for equipment, buildings, and personnel, while also collecting dust to reduce environmental pollution;4. Combined use with explosion isolation valves not only prevents pressure waves and flames from propagating to upstream production areas but also mitigates secondary explosions, reducing property damage and ensuring personnel safety.Product Parameters:Static activation pressure: 0.01 MPa;Frame material: Carbon steel or stainless steel;Flame arrestor material: 304SS;Applicable dust: St1 and St2 dust with Kst ≤ 300 barg·m/s, with effective venting area meeting explosion venting requirements;Product classification: Based on application scenarios, it can be divided into rectangular flameless explosion venting devices and curved flameless explosion venting devices;Applicable equipment: Dust collectors, bucket elevators, drying equipment, cyclone separators, dust collectors;Industries: Wood processing, plastics, spraying, food and dairy, plastic and dye processing, grain storage and processing, pharmaceuticals, coal processing, brewing, chemicals, metal processing, chemicals, power, cement, and other industries.Working Principle of Flameless Explosion Venting Device for Dust Collector Venting Port in Brewery WorkshopWorking Principle:The flameless venting device consists of two parts—an explosion venting panel and a flame quenching module. The explosion venting panel responds to rapid increases in deflagration pressure, immediately opening to reduce pressure. When the expanding fireball passes through the open venting panel, it is intercepted by the flame quenching module. The stainless steel precision mesh, supported by a frame, acts as a three-dimensional flame trap, extinguishing the flame and preventing its propagation, thereby avoiding secondary or multiple explosions. The flame quenching module eliminates deflagration flames, reduces the temperature of hot gases, and captures both burning and unburned dust passing through the open venting panel.Simultaneously, pressure waves or noise generated by production equipment are significantly reduced. As flames pass through the mesh flame arrestor, heat exchange occurs between the arrestor and the flames, rapidly cooling the high-temperature flames, venting pressure and smoke, while further reducing pressure waves or noise from production equipment.Application Fields:Widely used in industries such as grain, metallurgy, chemicals, power, light industry, tobacco, pharmaceuticals, machining, and solid waste treatment. Applicable equipment includes cyclone separators, bag dust collectors, dust collectors, cartridge filters, pneumatic conveying systems, rod or ball mills, bucket elevators, dryers and ovens, roller mills, and buildings.With increasingly stringent environmental inspections, safety has become a major concern. In the past, explosion venting panels were commonly installed on dust collectors to release overpressure caused by dust explosions. However, such installations on indoor equipment are not permitted by safety regulations because they endanger surrounding personnel and equipment. The pressure waves and flames from explosions may cause secondary or multiple explosions, posing risks. Therefore, relying solely on explosion venting panels for dust collectors is unreliable. We recommend using flameless explosion venting + isolation technology (a cost-effective solution) or suppression + isolation technology to ensure production safety.There are three main methods for dust explosion protection: venting, isolation, and suppression.Venting: Releases explosion pressure in advance through a pressure relief device to protect equipment from damage.Isolation: Uses an explosion isolation valve to block the explosion and prevent flame propagation.Suppression: Detection devices identify sparks and trigger fire suppression systems to instantly extinguish flames, preventing explosions. more>

Product Description: White copper bar is a nickel-zinc-copper alloy. White copper bars based on copper and nickel-zinc alloy with the addition of other elements such as lead, manganese, and aluminum are correspondingly referred to as lead white copper bar, manganese white copper bar, aluminum white copper bar, etc. Copper-nickel-zinc alloys exhibit good corrosion resistance, moderate strength, high plasticity, and can be processed under hot and cold pressure conditions. They also possess excellent electrical properties, making them not only suitable as structural materials but also important for high-resistance and thermocouple alloys.Common white copper bars mainly include four grades: B0.6, B5, B19, and B30. The most commonly used grades in the market are B12, B18, and C7941. The American standard includes a wider range of grades. White copper bar is a continuous solid solution formed by Cu and Ni, with a face-centered cubic lattice, as shown in Figure 1-18. When the temperature is below 322 degrees Celsius, the copper-nickel phase diagram exhibits a relatively broad metastable decomposition region in terms of composition and temperature. Adding a third element such as Fe, Cr, Sn, Ti, Co, Si, or Al to Cu-Ni alloys can alter the range and position of the metastable decomposition region while also improving certain properties of the alloy.Common white copper bars have good cold and hot working properties. They can be easily processed into various shapes such as plates, strips, tubes, bars, profiles, and wires. They also have good welding performance, allowing for soft and hard soldering, gas-shielded arc welding, and resistance welding. Their machinability is 20% that of free-cutting brass HPb63-3.Common white copper bars offer good corrosion resistance, moderate strength, high plasticity, and the ability to undergo cold and hot pressure processing. They also exhibit excellent electrical properties, making them not only suitable as structural materials but also important for high-resistance and thermocouple alloys. more>

Product Description: Long-lasting pad printing silicone with no oil seepage or sticky residue, offering extended service life and high print countsApplications of Pad Printing Silicone:Pad printing silicone is specifically used for manufacturing pad printing pads. It is primarily applied in printing on plastic toys, electroplated products, electronic toys, trademarks, and irregular patterns. The pad printing pad acts as a carrier to transfer patterns from the steel plate onto toy products.Features of Pad Printing Silicone:1); Low viscosity, good fluidity2); No shrinkage, easy ink application, clear printed patterns3); Fine texture, excellent rebound, high number of printing cycles4); Professional-grade pad printing silicone is designed for manufacturing printing pads. It requires a fine texture, free of impurities and particles, with good rebound. Made from high-quality raw materials and enhanced with DuPont's high-temperature resistant new material, it offers advantages such as wear resistance, high-temperature tolerance, and excellent printing results.Operation of Pad Printing Silicone:① First, clean the mold thoroughly with detergent, then wipe or blow dry any moisture, and apply a layer of release agent.② The standard ratio of pad printing silicone to silicone oil is determined based on customer requirements. If the customer needs to print large patterns and requires a softer pad, more silicone oil should be added. Conversely, for a harder pad, little or no silicone oil should be added. Generally, the hardness of a pad printing pad should be between 15A° and 25A°. Excessive silicone oil will make the pad too soft, limiting the number of prints. Even the highest quality silicone can be compromised by excessive silicone oil, leading to reduced wear resistance, solvent resistance, and accelerated aging.③ A typical ratio is as follows: 100g of silicone with 30g of silicone oil, resulting in a pad hardness of 20A°, suitable for printing small patterns on alloy car models and products with small contact areas. For larger contact areas or softer pads, ratios such as 100:30 or 100:50 can be used. However, note that higher silicone oil content softens the pad, reducing the number of prints, wear resistance, and solvent resistance. This increases costs and wastes materials.④ The curing agent ratio and chemical reaction of silicone are as follows: Take 100g of silicone and 50g of silicone oil, mix thoroughly. After ensuring even distribution, add 2%–3% of the total weight of silicone and silicone oil as curing agent, then stir for another 2–3 minutes. Proceed to degassing, which should not exceed 10 minutes. Excessive degassing time may cause premature curing, affecting the quality of the silicone.Principles of Pad Printing Pad Manufacturing:a.; The vulcanization system of rubber is the foundation of significant advancements in the rubber industry. Pad printing pads are made using the principle of room-temperature vulcanized silicone rubber cross-linking into a network-structured elastomer under the action of vulcanizing agents.b.; Rubber consists of large molecular chain hydrocarbons. Rubber with only carbon atoms in the main chain is called carbon-chain rubber; rubber with other atoms besides carbon in the main chain is called heterochain rubber. If the main chain contains organic groups with atoms like silicon (Si), tin (Sn), or boron (B), it is termed an elemental organic polymer. Silicone rubber is an elemental organic polymer with organosilicon groups in its main chain. There are two vulcanization processes for silicone rubber: high-temperature vulcanization, corresponding to high-temperature vulcanized silicone rubber (HTV), and room-temperature vulcanization, corresponding to room-temperature vulcanized silicone rubber (RTV). RTV silicone rubber is further divided into addition-type and condensation-type.c.; Condensation-type silicone rubber contains terminal hydroxyl groups (-OH), which easily react with silanes containing hydrolyzable groups (-OCH3, -OCOCH3) for room-temperature vulcanization. The cross-linking agent is ethyl silicate, and the catalyst is dibutyltin dilaurate. Addition-type silicone rubber typically contains -CH=CH terminal groups and usually uses polysiloxane with Si-H bonds as a cross-linking agent for self-addition reactions to form an elastomer.  more>

Product Description: A spectroscope is an optical component that splits a beam of light into two beams with specific reflection and transmission ratios. Its core principle involves using a dispersion element (such as a prism) to decompose white light into light of different wavelengths, forming a continuous visible light spectrum. This characteristic allows the selective absorption patterns of pigments in gemstones to be used for gem identification, determining the type of gemstone and the cause of its coloration by identifying fixed absorption band positions. In optical paths, the spectroscope primarily functions to separate light source energy and alter the direction of the light path. It features a simple structure, minimal light absorption, and low loss after spectral splitting.Classification and Structural Characteristics of SpectroscopesClassification by Structural FormCube Spectroscope: Composed of two right-angle prisms bonded together, with one prism's斜面 coated with a spectral splitting film, forming a cubic structure. Its advantages include high effective diameter utilization in all directions and ease of optical adjustment, making it suitable for compact optical systems. However, large-aperture products are heavier and more costly, and may produce a small amount of back-reflected light (within 1%).Plate Spectroscope: Designed based on a flat glass plate with a single surface coated with a spectral splitting film. It offers lower cost and lighter weight, making it suitable for applications with limited space or cost sensitivity. However, it suffers from issues such as optical path differences between reflected and transmitted light, which may cause astigmatism and beam displacement. At a 45° incidence angle, the effective diameter appears elliptical. more>
