See how Zhengda coal granular activated carbon improves our water quality

How can coal-based granular activated carbon improve our water quality, unimaginable clarity! Zhengda coal granular activated carbon is made of high quality anthracite and tar as raw materials and refined by advanced technology. The appearance is black columnar particles. It has the characteristics of developed porosity, large specific surface area, strong adsorption force, high mechanical strength, easy repeated regeneration and low cost. Widely used in toxic gas purification, waste gas treatment, industrial and domestic water purification treatment, solvent recovery and other aspects.
A uniform standard for quality control of coal-based columnar activated carbon. Therefore, the establishment of relevant activated carbon standards for cigarettes has important guiding significance for the development of activated carbon composite nozzles in enterprises within the industry. Formulate the inspection of the activated carbon industry and domestic and international standards: Performance indicators The production process of activated carbon filters is required to suppress the generation of dust, so we hope to set a higher strength index. According to the production practice of a number of activated carbon filter rod manufacturers, from the viewpoint of suppressing dust and protecting the cutting edge, the strength of the activated carbon for cigarettes is more than 90%, which is convenient for processing and utilization.

Zhengda coal-based granular activated carbon in Japan's East Asian neighbors Japan and South Korea, activated carbon composite filter cigarettes dominate the market. In China, the strength plays a very important role. According to the domestic and international activated carbon standards, the main physical properties of Hohhot coal-based columnar activated carbon are: shape, appearance, specific surface area, pore volume, specific gravity, mesh number, particle size and strength. : It is mainly based on the test results and production experience of activated carbon samples from many domestic cigarette companies and filter rod manufacturers. At the same time, a small amount of reference to GB/T02-1999 indicators of the quality standards of granular activated carbon for wood purification, according to the characteristics of activated carbon for cigarettes, the following indicators are drawn. There are many kinds of activated carbon plants in the country, and the production level is not the same. In the composite nozzle of cigarettes, activated carbon is the most important component. In order to ensure the quality of the composite nozzle cigarette products, it is necessary to adsorb the non-condensable gas phase harmful components. The performance indexes of coal-based columnar activated carbon products can be divided into physical indicators (including functional indicators), chemical indicators, safety indicators and other common indicators. Selection of four kinds of performance indicators for activated carbon and application test methods There are many types of coal-based columnar activated carbon. According to different raw materials, it can be divided into plant raw material carbon, coal charcoal, petroleum carbon and other carbon (such as pulp waste liquid carbon, synthetic resin). Carbon, organic waste charcoal, bone charcoal, blood charcoal, etc. China is a large country in the production and consumption of cigarettes. Activated carbon filter smoke can greatly improve the filtering effect on flue gas and reduce harmful components in flue gas. As a variety of low-toxic cigarettes, The main purpose of the standard in China in the future is to unify the quality level of activated carbon used in the whole industry, to promote the production of activated carbon production enterprises, and to better serve the cigarette industry.

The function of Zhengda coal-based granular activated carbon is dark black columnar particles or amorphous particles. It has a large specific surface area, suitable pore structure, high mechanical strength, can withstand high temperature and high pressure, is not easy to break ash, and has a long service life. Features.

Zhengda coal granular activated carbon use coal granular activated carbon is widely used in chemical raw material gas, chemical synthesis gas, pharmaceutical industry gas, beverage carbon dioxide gas, hydrogen, nitrogen, chlorine, acetylene, ethylene, cracked gas, inert gas, etc. Purification, separation and purification of atomic facilities such as exhaust gas.

Stop Valves

Stop Valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.
