Staple fiber product

At present, our country has about 40 sets of municipal solid waste incinerator and hazardous solid waste incinerator, all adopt the PTFE long and short fiber products made by this project. The total filtration area is about 700000 square meters, the total amount of PTFE fiber is about 595.31 tons. For example, in 2009 the whole year, for the production of garbage incinerator bag filter media used in the PTFE long fiber is 40 tons, the amount of short fiber reached 240 tons, accounting for 91% of the total amount of waste incineration.

In the power industry, has 9 power plants use bag made of PTFE fiber fabric production of this project, a total area of 24. 50 thousand square meters, with a total weight of about 36.75 tons of PTFE fiber. Polytetrafluoroethylene base cloth for China electric power industry has 30000 hours filter service life provide critical support to the current market rate of more than 50%. Pure PTFE fiber membrane filter in continuous use temperature up to 250 DEG C, instant working temperature reached 280 degrees, acid and alkali resistant and is not hydrolyzed from being oxidized. Service life of up to 4 years, far more than ordinary plastic film filter media.

According to the introduction, the PM2.5 is a particle that is less than or equal to 2.5 microns in diameter, also known as the can enter the lung particles, air quality and visibility, etc.. Compared with the coarse atmospheric particles, the PM2.5 particle size is small, which contains a large amount of toxic and harmful substances, and has a long residence time in the atmosphere, and the transmission distance is far, so it has a greater impact on human health and the quality of the atmospheric environment.

In most parts of China, especially in the North China region of industrial concentration, the PM2.5 accounts for more than half of the total weight of the suspended particulate matter. PM2.5 is the main cause of haze weather, and past China's environmental air quality standards in PM2.5.

The environmental protection department recently released the "environmental air PM10 and PM2.5 determination method", for the first time in the air, the diameter of less than 2.5 microns in the determination of particulate matter PM2.5. The filtration efficiency of dust removal products using polytetrafluoroethylene base cloth and coated filter material of PM2.5 as high as 99.99%.

These are China's implementation of energy-saving emission reduction policies has made a great contribution, our country in the critical areas of the PTFE filter media is no longer controlled by others, and for the country save the cost of investment in environmental protection.
