General dust bag polyester needle felt continuous working temperature can reach 130 ℃, if the temperature exceeds 130 ℃ long-running dust bag, then it will lose a lot of strength, but also have a huge contraction, so the size of the dust bag occurrence change, thereby affecting the filtering effect. Nine are brightly lit using a special process to produce aromatic Manchester needle felt is made of glass fiber woven fabric, which together with high-quality polyester (polyester), PPS, Kerouac masterpiece surface layer, it has a high breaking strength, elongation at break is small, small heat shrinkage, temperature and other characteristics at room temperature moderate dust bag, to meet the temperature requirements at 150 ℃ ~ 170 ℃ high temperature dust bag, dust bag at room temperature and can not meet the high-temperature dust bag and too wasteful needs, operating costs can be reduced largely. Dust bag suitable for coal-fired flue gas dust, but poor ability of antioxidants, although polyimide fibers can compensate for their lack of dust bag manufacturer, but not ideal hydrolytic stability. As a "plastic" Teflon fiber has the best chemical resistance, but more expensive. Dusty gas is divided into three states according to the relative humidity: the relative humidity at 30% or less for the drying gas, the relative humidity of 30% -80% for the general state, the gas relative humidity above 80% is the high-humidity gas. When humidity for gas, but also in high temperature, especially when dusty gas containing SO3, gas cooling will produce condensation. This will not only make the bag surface fouling, clogging and corrosion of structural materials, and therefore need special attention in the temperature dust bag dust bag _ _ Guangdong brightly lit dust by dust Equipment Co., Ltd. Botou brilliance. Botou brightly lit dust Equipment Co., Ltd. (www.tmccsb.com) strong, credible, environmentally friendly products in Hebei Cangzhou processing industry has accumulated a large number of loyal customers.
