It uses ceramic fiber composite materials as support and, by loading specific catalysts, achieves the simultaneous removal of multiple pollutants in a single unit. It offers advantages such as high efficiency, energy savings, environmental friendliness, and a small footprint. Below is a detailed introduction to this equipment:     I. Technical Principle     The glass furnace ceramic fiber filter tube integrated desulfurization, denitrification, and dust removal equipment utilizes the multi-gradient microporous structure of ceramic fiber filter tubes to efficiently capture particulate matter in flue gas. Simultaneously, the catalysts loaded on the filter tube surface promote the catalytic oxidation and neutralization reactions of SO₂ and NOx as the flue gas passes through, thereby achieving desulfurization and denitrification. Additionally, depending on the composition of the flue gas, the equipment can be paired with different additives to remove acidic gases (such as SO₂, HCl, HF, etc.).     II. Main AdvantagesHigh Purification Efficiency:Ceramic fiber filter tubes offer extremely high filtration precision, with a capture efficiency of over 99.9% for ultrafine dust such as PM2.5, and emission concentrations far below national standards.Through the loaded catalysts, the equipment achieves high-efficiency desulfurization and denitrification, with desulfurization efficiency ≥92% and denitrification efficiency ≥90%.Corrosion Resistance and Long Service Life:Ceramic fiber filter tubes are made of high-temperature and corrosion-resistant composite materials, capable of withstanding high-temperature, highly corrosive flue gas environments. Their service life ranges from 3 to 10 years, far exceeding that of traditional filter bags.The equipment eliminates the need for additional water spray cooling or wet desulfurization processes, avoiding issues such as filter bag damage caused by condensation and acid-base corrosion in traditional methods.Energy Saving and Consumption Reduction:The equipment adopts dry desulfurization technology, eliminating the need for slurry preparation systems and avoiding wastewater generation and treatment costs.The smooth surface of the filter tubes results in low system resistance and energy consumption, reducing energy use by over 30% compared to traditional bag dust collectors.The built-in heat recovery system converts waste heat from flue gas into preheated air or steam, improving energy utilization efficiency.Intelligent Control:The equipment incorporates AI algorithms to monitor flue gas parameters in real time, automatically adjusting blowing frequency and catalyst activity to ensure efficient operation while minimizing energy consumption.It supports remote monitoring and intelligent maintenance, reducing operational and maintenance costs.Small Footprint:The equipment features a modular design with high integration, occupying a small area, making it suitable for retrofitting older production lines with limited space. more>

It is sterile water used for preparing drug solutions, undergoing strict sterilization and filtration processes to ensure it is free from any microbial contamination, making it suitable for injection or intravenous infusion. It serves as a solvent or diluent for various pharmaceutical preparations and is widely used in medical institutions such as hospitals and clinics.Usage Instructions for Medicinal Grade Sterile Water for Injection (Sterile Water) with National Drug Approval NumberMedicinal grade sterile water for injection itself does not contain active pharmaceutical ingredients, so its usage is typically related to the drug formulations it is used to prepare. Below are several common methods of use:1. Dissolving Medications:In clinical settings, medicinal grade sterile water for injection is often used to dissolve or dilute medications intended for injection. Drugs such as antibiotics and hormonal medications usually require dissolution in sterile water before being administered. The dosage should be used correctly according to the drug's instructions or a doctor's prescription.2. Diluting Drug Solutions:For certain medications (such as some chemotherapy drugs or potent medications), dilution is often necessary to reduce concentration and avoid irritation or excessive drug reactions in patients. Medicinal grade sterile water for injection plays a critical role in this regard. Doctors will adjust the amount of water and medication based on the drug's instructions and the patient's specific condition.3. Intravenous Infusion:Medicinal grade sterile water for injection is commonly used as part of intravenous infusions, mixed with medications for intravenous drip administration. In this context, the sterile water helps transport the medication quickly through the bloodstream, ensuring timely efficacy.4.

Product Description: Brass Rod:Brass rod is a type of non-ferrous metal processing bar with good processing performance and high electrical conductivity. It is mainly divided into brass rods (copper-zinc alloy, relatively cheaper) and copper rods (higher copper content).Brass rods are bar-shaped objects made from an alloy of copper and zinc, named for their yellow color. Brass with a copper content of 56% to 68% has a melting point of 934 to 967 degrees Celsius. Brass has excellent mechanical properties and wear resistance, making it suitable for manufacturing precision instruments, ship parts, etc.Different zinc content results in different colors. For example, a zinc content of 18%-20% gives a reddish-yellow color, while a zinc content of 20%-30% results in a brownish-yellow color. Additionally, brass produces a unique sound when struck, which is why Eastern musical instruments such as gongs, cymbals, bells, and horns, as well as Western brass instruments, are made of brass.Brass is an alloy of copper and zinc. Simple brass is a binary alloy of copper and zinc, known as simple brass or common brass. Changing the zinc content in brass can yield different mechanical properties. The higher the zinc content in brass, the greater its strength, though its plasticity decreases slightly. The zinc content in brass used in industry does not exceed 45%, as higher zinc content leads to brittleness and deteriorates the alloy's properties. To improve certain properties of brass, other alloying elements are added to simple brass, resulting in what is known as special brass. Commonly used alloying elements include silicon, aluminum, tin, lead, manganese, iron, and nickel. Adding aluminum to brass increases its yield strength and corrosion resistance while slightly reducing plasticity. Brass with less than 4% aluminum has good comprehensive properties for processing and casting. Adding 1% tin to brass significantly improves its resistance to seawater and marine atmospheric corrosion, hence it is called "naval brass." Tin also enhances the machinability of brass. The main purpose of adding lead to brass is to improve machinability and wear resistance, with lead having little effect on the strength of brass. Manganese brass has good mechanical properties, thermal stability, and corrosion resistance. Adding aluminum to manganese brass can further improve its properties, resulting in castings with a smooth surface. Brass can be divided into two categories: cast products and pressure-processed products. more>

Product Description: What does the IEC60825 testing process and report test? How is IEC60825 determined to be compliant?What does the IEC60825 testing process and report test? How is IEC60825 determined to be compliant?IEC60825 is the testing standard for laser products, an international standard test report, with CNAS accreditation.The IEC60825-1:2014 version testing for laser modules is relatively simple, with the basic requirement being that the laser class meets the standards.Samples required for IEC60825 testing of laser modules: 2 pieces per model with one driver power supply.Keywords related to IEC60825-1:2014:IEC/EN60825 primarily involves energy testing and calculation for single-wavelength light.IEC/EN62471 mainly measures broad-spectrum light and calculates based on factors such as time, angle, and sensitivity of human eye and skin reactions to light.Products applicable to IEC60825-1:2014:All lamps and lamp systems except lasers. (Single-wavelength lasers are easy to test, whereas ordinary lamps may be broad-spectrum light sources due to the influence of emitters, diffusers, lenses, auxiliary optical components, etc.)Wavelength range tested by IEC60825-1:2014:Optical radiation with wavelengths ranging from 200nm to 3000nm.Parameters and objects tested by IEC60825-1:2014:Test parameters:1. Irradiance (radiant flux divided by unit area, unit: W·m⁻²)2. Radiance (irradiance divided by field of view, convertible from irradiance)Test objects:3. Ultraviolet hazards to skin and eyes4. Near-ultraviolet hazards to the eyes (315nm-400nm)5. Retinal blue light hazard6. Retinal thermal hazard (for weak visual stimuli) (780nm-1400nm)7. Infrared radiation hazard to the eyes (780nm-3000nm)8. Skin thermal hazard (380nm-3000nm)IEC 60825 is the testing standard for laser products, used to evaluate whether laser products meet international safety requirements. Test reports typically include the following main contents:Test parameters and objects:Irradiance (radiant flux divided by unit area, unit: W/m²)Radiance (irradiance divided by field of view, convertible from irradiance)Ultraviolet hazards to skin and eyesNear-ultraviolet hazards to the eyes (315nm-400nm)Retinal blue light hazardRetinal thermal hazard (for weak visual stimuli) (780nm-1400nm)Infrared radiation hazard to the eyes (780nm-3000nm)Skin thermal hazard (380nm-3000nm)Judgment of test results:Continuous lamps: No hazard; Class 1 hazard (low risk); Class 2 hazard (medium risk); Class 3 hazard (high risk)Pulsed lamps: Those exceeding radiation limits are classified as Class 3 hazard; single-pulse lamps not exceeding radiation limits are classified as no hazard; multi-pulse lamps not exceeding radiation limits are classified using the continuous lamp classification method, Level 1Confirmation of laser product categories:Determine the category of the laser product, such as Class 1, Class 2, Class 3A, Class 3B, Class 4, etc., based on the definitions in the IEC 60825 standard.Other related tests:Output power test: Measure the output power of the laser product to ensure it falls within the range specified by the standard.Wavelength test: Measure the wavelength of the laser beam produced by the laser product to ensure it meets the relevant requirements of the standard.Beam quality test: Observe and analyze the focusing and divergence of the laser beam using optical instruments.Safety tests: Conduct tests on laser products under extreme conditions such as overload, short circuit, and overheating to evaluate the product's safety performance.Reliability tests: Assess the long-term stability and reliability of laser products.Label verification: Ensure that laser products are correctly labeled with information such as laser class and output power on their appearance and documentation.How to determine compliance:Conformity assessment: Test results must be compared with the requirements in the IEC 60825 standard to ensure all test parameters meet the standard limits.Category determination: Based on test results, laser products are classified as Class 1, Class 2, Class 3A, Class 3B, or Class 4, with different categories corresponding to different safe usage conditions.Hazard level: Assess the hazard level of the laser product based on its usage conditions and radiation characteristics, and determine corresponding safety measures.The final test report will provide detailed testing methods, test results, and conclusions to enable manufacturers and regulatory agencies to accurately evaluate the product's safety. It is recommended that manufacturers strictly follow the IEC 60825 standard during the design and production of laser products to ensure product safety and compliance.The IEC 60825 report testing process typically includes the following steps:Confirm product requirements:Determine whether the product requires IEC 60825 testing based on its characteristics and intended use.Select a testing laboratory or certification body:Choose an accredited laboratory or certification body with IEC 60825 testing qualifications, ensuring it has relevant certifications and experience in the IEC 60825 standard.Negotiate the testing scope:Discuss the specific testing scope with the selected testing laboratory or certification body, determining the test items required, including output power, wavelength, safety, and other aspects.Submit test samples:Provide a sufficient number of samples for testing. These samples should be representative of the production process to ensure test results reflect the actual product performance.Test execution:The testing laboratory or certification body executes the testing methods specified in the IEC 60825 standard, including measuring the output power and wavelength of the laser product, and conducting safety tests to ensure the product meets the relevant requirements of the standard.Generate test report:After testing is completed, the testing laboratory or certification body will generate an IEC 60825 test report, which should include detailed product information, testing methods, test results, and conclusions on compliance with the standard.Report review:The manufacturer or applicant reviews the test report to ensure the information is accurate.Submit certification application:If required, the manufacturer can submit the IEC 60825 test report along with other necessary documents to the regulatory agency to obtain IEC 60825 certification.Wait for review:Wait for the certification body to review the application. The review time may depend on the workload and review process of the certification body.Obtain IEC 60825 certificate:If the product passes the review, the manufacturer will receive an IEC 60825 certificate, which typically needs to be indicated on the product.Ongoing compliance:Once the IEC 60825 certificate is obtained, ensure the product continues to meet the requirements of the IEC 60825 standard. If the product changes, it may be necessary to resubmit the certification application.Recommendations:Before conducting IEC 60825 testing, it is recommended to collaborate with a professional testing laboratory or certification body to ensure the accuracy of testing and the reliability of the report.Maintain good communication with the certification body and submit necessary documents and samples promptly to complete the certification process smoothly. more>
