Basalt fiber has the properties of high temperature resistance (up to 700 ° C), low thermal conductivity (0.04w / m.k), non-conductivity, non-combustion, etc. It has excellent performance as a building exterior wall insulation or tunnel fire-resistant decorative board. Basalt fiber as the thermal insulation material of the external wall insulation and decoration integrated board, is a collection of thermal insulation, flame retardant, water resistance, decoration four-in-one high-performance exterior wall board.
Applications:
It is widely used in building exterior wall external insulation system, building aluminum curtain wall system, building interior decoration sound insulation wall system, aluminum gusset ceiling sound absorption system and roof insulation system.
Basalt fiber high-temperature corrosion-resistant filter material, filter bag
product description
The fiber raw materials for the production of industrial filter materials are polypropylene, polyphenylene sulfide, aramid, polyimide, polytetrafluoroethylene and glass fiber, which can withstand a maximum filtration temperature of only 260 ° C. There are many filtration environments above 300 ° C in industrial production, and chemical filter materials are required to be resistant to acid and alkali corrosion and the chemical properties of the filter material are stable. So all this suggests that basalt fiber material will be an excellent filter cloth raw material with wide application prospects and huge market capacity.
2. Basalt fiber high temperature filter bag uses high tensile strength basalt fiber, which has high temperature resistance, acid and alkali corrosion resistance, oxidation resistance, water repellency and stable size. It can meet the harsh dust removal operation environment, improve dust removal efficiency, and extend filtration Bag life.
Applications
Basalt fiber high-temperature filter bags have a wide range of applications, and their main use is to make bag filters for dust removal or collection products in the steel, chemical, cement, carbon black, and food industries. Bag type dust collector (bag type dust removal technology) is an efficient dust removal device for air pollution control. The biggest advantage is that the dust removal efficiency is high. In practice, it can reach 99.99%. The dust emission concentration can reach below 10mg / m3, or even 2mg / m3. Of all the dust removal equipment, the bag dust collector has the highest dust removal efficiency.
Product advantages
1. High mechanical strength, the breaking strength is generally above 3000N;
2. The elongation is low, and the elongation at break of the basalt fiber itself is only 3%, so the size of the filter bag made of it is stable;
3. Good mechanical properties, can be used for a long time at 650 ℃;
4. Good corrosion resistance, can be used in acid and alkali gas;
5. The fabric has high porosity, smooth surface, good air permeability, and no-load pressure loss is only 2Pa;
6. High dust collection efficiency, which can reach 99% -99.5%, especially for dust particles below 0.5mm in diameter, the effect is more obvious;
7. Strong adaptability to flue gas dust concentration;
8. Large amount of smoke and dust, convenient operation and maintenance, easy to clean dust; 灰
9. Long life.
