Product Description: Hengwang Activated Carbon - Conventional Specifications of Columnar Activated Carbon:Iodine Value: 1400/1200/1000/800/600/400/200Diameter: 1.5-8mmIntroduction to Columnar Activated Carbon:Columnar activated carbon is made from coal, coconut shell, and wood chips as raw materials. It is widely used in nitrogen purification equipment and air separation nitrogen production equipment, and is particularly suitable for post-stage purification and oil absorption in pressure swing adsorption nitrogen production. It appears as black cylindrical granules.Columnar activated carbon has a very high effective adsorption rate in the field of air purification, with a CTC adsorption rate of over 90%. It also has a good adsorption effect on volatile organic compounds in water, achieving a removal rate of 25% to 65% for various volatile organic compounds in water. By comparing the adsorption patterns of different molecular weight organic compounds, it can be observed that for volatile organic compounds, the larger the molecular weight, the higher the removal rate. This is similar to the adsorption patterns of phenol and cationic soft yellow, meaning that for small organic molecules in water, the larger the molecular weight, the more easily they are adsorbed by activated carbon.Activated carbon has an excellent removal effect on extractable organic compounds with molecular weights below 480, but a low removal efficiency for large organic molecules. This is mainly due to the steric hindrance effect of the micropore structure of activated carbon, which prevents overly large organic molecules from entering the pores of the activated carbon, allowing only surface adsorption.Applications of Columnar Activated Carbon:Widely used in gas treatment, sewage treatment, desulfurization and denitrification, solvent recovery, nitrogen generators, air separation equipment, painting workshops, and other fields.For example:Water treatment industry: Columnar activated carbon is used to remove organic matter, odors, pigments, chlorine, and other pollutants from water, making it a key component in the water purification process.Air purification: In air purifiers and gas masks, columnar activated carbon is used to adsorb harmful gases and particles, such as formaldehyde, benzene, and other volatile organic compounds (VOCs).Chemical and pharmaceutical industries: In the refining of chemical products and pharmaceutical processes, columnar activated carbon is used to adsorb impurities and purify products.Food and beverage industry: Used to remove pigments, odors, and impurities from food and beverages, improving product quality.Electronics industry: In semiconductor and electronic manufacturing processes, columnar activated carbon is used to purify gases and chemicals, ensuring product quality.Environmental protection: In industrial exhaust gas treatment, columnar activated carbon can adsorb harmful components in gases, reducing environmental pollution.Metal extraction and electroplating: In metal extraction and electroplating processes, columnar activated carbon is used to adsorb metal ions, improving recovery rates and product quality.Solvent recovery: In industries such as chemicals and printing, columnar activated carbon is used to adsorb and recover organic solvents, reducing waste and environmental pollution.Precautions for Using Columnar Activated Carbon:Not all columnar activated carbon can adsorb harmful gases. Only when the pore structure of the columnar activated carbon is slightly larger than the diameter of the harmful gas molecules, allowing the harmful gas molecules to fully enter (neither too large nor too small), can optimal adsorption be achieved. Currently, the market mainly features bamboo charcoal and Wujin charcoal crafts. Wujin charcoal is extremely expensive, with an iodine adsorption index of only about 650 mg/g. Bamboo charcoal products also have an iodine adsorption index of only about 700 mg/g. Our company's modified columnar activated carbon, compared to similar products on the market, offers excellent adsorption performance and high cost-effectiveness. more>

Perfluoroether rubber can withstand corrosion from over 1,600 chemical solvents, including strong acids, strong alkalis, organic solvents, ultra-high-temperature steam, ethers, ketones, esters, nitrogen compounds, hydrocarbons, alcohols, aldehydes, furans, amine compounds, and more. It can endure temperatures up to 320°C. FFKM perfluoroether components have been used in numerous industries for nearly 40 years with practical application experience.Rubber Seal Ring Sealing Pressure Test Method:This test method measures the pressure exerted by the seal on the material installed in its groove, simulating actual usage conditions. It measures the force required to open the seal lip to the thickness of the material it seals. For double-groove seals, this method involves inserting a metal restrictor of specified thickness into one groove and conducting the test on the other groove. Thus, the test results reflect the pressure of the sealing lip during use.Equipment:1. Tensile testing machine, compliant with HG/T2369 requirements, with B-grade accuracy.2. Fixture3. Lip separator, made of stainless steel, used for molded corner specimens4. Metal restrictor, used when testing double-groove seals. Its width should match the specimen's width, and its thickness should match the installed material's thickness.Extruded specimens should be actual seal pieces with a length of at least 20mm but not more than 305mm. At least four specimens per batch should be tested.Corner specimens should have both sides measuring 25mm from the inner corner. At least four specimens per batch should be tested.An important step in production is vulcanization, which transforms the linear polymer structure into a three-dimensional polymer structure. Sulfur forms covalent bonds between two polymer chains, creating a three-dimensional structure and enhancing the rubber's properties. Therefore, controlling vulcanization is crucial. However, before vulcanization, the rubber must undergo mixing, adding vulcanizing agents and reinforcing agents to improve its properties.Benefits of Vulcanized Rubber:It exhibits characteristics such as non-stickiness and resistance to breakage.1. Molding: It can be molded into desired shapes using vulcanizing machines, either by compression molding or extrusion.2. Customization: Specific additives can be incorporated to achieve desired properties.Most rubber products are made from vulcanized rubber, also known as cured rubber or simply "rubber."
