One Micron Water HEPA Polyester Felt Filter Bag Flame Retardant Treatment High Density

One Micron Water HEPA Polyester Felt Filter Bag Flame Retardant Treatment High Density

Polyester is not resistant to strong alkali, poor hydrolysis resistance, water vapor of 5% or more, can be hydrolyzed at 100 °C, especially at higher temperatures; weak acid resistance, stable to general mailing solvents. Jiehua Company can waterproof and oil-proof, anti-static, PTFE acid and alkali treatment and flame retardant treatment of polyester needle felt, and it can cope with special working conditions to ensure long-term durability

Running polyester dust bag is made of high-frequency, high-density and high-speed production line of Sinopec Yizheng high-quality polyester fiber and polyester fine-woven fabric. All technical indexes are in line with GB/T6719-2009 standard. The product has high porosity and density. Good, high filtration precision, good ventilation and easy to clean. The vitrification temperature of polyester fiber is about 80 °C, the melting point is 255°C-265°C, the burning temperature is 450°C, and the softening starts at 230°C-240°C. It is a heat-shrinkable fiber. The strength loss caused by heating at 170°C for a short time can be Recovery, so polyester fiber has good performance at room temperature. It can work continuously for a long time below 120 °C.

Our company choose different type fineness polyester fiber make into the gradient type structure filter material,make the product not only have the common felt's advantage of high voidage,good air permeability high dust collecting effciency,long service life,etc.But also have the advantage of the moderate temperature rating,can reach 150℃ at the moment,moderate effect of the antiantacid and antialkai,and has very good abrasion resistance.Weight from 350g/m²-600 g/m²,thickness from 1mm to 4mm,width below 2.5meters,such cloth our factory all could produce,and can be cut to various width,just as your mind request.

According to the different requirements to the different working condition,surface treatment can be done as singeing,calendering,oil and water proof,PTFE impregnation,coating,laminating process,etc.
