Filter bag introduction

The water-repellent oil-repellent needled felt adopts the special surface post-treatment technology, which greatly improves the adhesion resistance of the filter media and the easy stripping of dust, and can effectively prevent water and all kinds of oil scale from sticking and penetrating. Reduce the accumulation and condensation of excessive dust on the filter bag to improve the dust removal capacity.

1Application: It is suitable for the occasion with high moisture content, such as pulverized coal injection in blast furnace of iron and steel plant, cement plant, coal transport system of power plant, etc. 3. The polyester three-proof needle felt produced by our company is made of 0.8-1.5D or finer fiber, which has the following characteristics:

1. High strength and low extension industrial silk as the base cloth, greatly improve the strength. 2. Selection of fine denier fiber, pore size reduction, high porosity, high filtration accuracy. 3. Selection of excellent polyester fiber, acid, alkali and hydrolysis resistance are enhanced. 4. The surface treatment is more smooth, with the surface filtering effect of coated filter material. 5. Low running resistance and energy saving.

Polyester three anti needle felt filter bag is mainly used in chemical industry, metallurgy, food, pharmaceutical, building materials, mining and other industries such as bag filter, plate and frame filter press, belt filter, vacuum filter and smoke dust removal and other solid-liquid separation, solid gas separation equipment.

Polyester anti-static needle felt products are mainly used in chemical, metallurgy, food, pharmaceutical, building materials, mining and other industries, such as bag dust precipitator, plate and frame filter press, belt filter, vacuum filter and smoke dust removal for solid-liquid separation. When the concentration of industrial dust reaches a certain level, such as electrostatic discharge sparks or external ignition and other factors, it is easy to cause explosion and fire, such as: Face dust, chemical dust, coal dust, such as electrostatic discharge in the event of explosion. In the field of bag dust removal, if the dust needs to be collected by cloth bags, the filter bag made is required to have anti-static property.

performance

Acid and weak alkali resistance. Good wear resistance, corrosion resistance, recovery and poor electrical conductivity. Heat resistance :130℃ fracture elongation (%):20-50 fracture strength (g/d):438. Melting point (℃): 238-240, melting point (℃): 255-260. Specific gravity :1.38.

Polyester anti-static needled felt has smooth surface, good wear resistance, high strength, higher strength and better wear resistance after twisting, so that the fabric has good breathability, fast water leakage and easy cleaning. The raw material structure of polyester anti-static needled felt is short and the wool woven fabric is dense, with good particle retention, but poor stripping and air permeability. Strength and wear resistance, water leakage is also less than polyester long fiber filter cloth.

Long fiber filter cloth

The polyester fiber adopts the solute imitation silk, the cross section is round, the surface is flat. Under standard conditions, the moisture recovery rate is 0.4%-0.5%, and when the relative humidity is 100℃, the moisture recovery rate is 0.6%-0.8%. Therefore, the fiber properties have little change in both dry and wet conditions. Good mildew resistance, moth-eaten performance, convenient storage. Long polyester fiber raw material structure is long and smooth. After twisting, polyester filament has higher breaking strength than short fiber because the finished product woven by smooth materials has better air permeability. Polyester filament has the characteristics of high strength, good water leakage and good wear resistance

Short fiber filter cloth

Short fiber press cloth raw materials with short structure and woolen fabric has good retention of dense particles, but poor stripping and air permeability. Strength and wear resistance, water leakage is also less than polyester long fiber filter cloth. Polyester filter cloth applications: pharmaceutical, food, chemical, metallurgy, industrial filter press, centrifuge filter cloth, etc.
