How can coal-based granular activated carbon improve our water quality? The result is truly astonishing in clarity! Zhengda coal granular activated carbon is made from high-quality anthracite and tar, using advanced technology. It appears as black cylindrical particles, featuring a highly developed pore structure, large specific surface area, strong adsorption capacity, high mechanical strength, easy regeneration, and low cost. It is widely used in gas purification, waste gas treatment, industrial and domestic water filtration, and solvent recovery.
To ensure consistent quality, strict standards are essential for coal-based columnar activated carbon. Establishing relevant standards for cigarette filters holds great significance for the development of activated carbon composite nozzles within the industry. These standards cover performance indicators, production processes, and dust suppression measures. Based on practical experience from several manufacturers, the strength of activated carbon used in cigarettes should exceed 90% to reduce dust and ensure smooth processing.
In Japan and South Korea, activated carbon composite filter cigarettes dominate the market. In China, the strength of activated carbon plays a crucial role. According to domestic and international standards, key physical properties of Hohhot coal-based columnar activated carbon include shape, appearance, specific surface area, pore volume, density, mesh size, particle size, and strength. These are based on test results and production experience from numerous domestic cigarette companies and filter rod manufacturers. Some references are also drawn from GB/T02-1999 standards for wood-based granular activated carbon, tailored to the needs of cigarette applications.
China is a major producer and consumer of cigarettes. Activated carbon filters significantly enhance the removal of harmful components from smoke. As part of low-toxicity cigarette development, future standards aim to unify the quality of activated carbon across the industry, promoting better production practices and supporting the cigarette sector more effectively.
Zhengda coal-based granular activated carbon comes in dark black cylindrical or amorphous forms. It has a large specific surface area, suitable pore structure, high mechanical strength, resistance to high temperature and pressure, minimal breakage, and a long service life.
Zhengda coal granular activated carbon is widely used in the purification of gases such as chemical raw materials, synthesis gases, pharmaceutical gases, beverage carbon dioxide, hydrogen, nitrogen, chlorine, acetylene, ethylene, cracked gas, and inert gases. It is also applied in the purification and separation of exhaust gases from industrial facilities.
