High temperature basalt filter bag

发布时间:2020-01-03 Edit: Release time: 2020-01-03

Basalt fiber filter. It is a continuous fiber made of platinum-rhodium alloy wire drawing plate after melting the basalt material at 1450 ℃ ~ 1500 ℃, and its strength is equivalent to that of high-strength S glass fiber. The color of pure natural basalt fibers is brown, and some are golden. Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material. It is a basalt material composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide, and titanium dioxide. After melting at high temperature, it quickly passes through the plate. Drawn. Basalt continuous fiber not only has high strength, but also has many excellent properties such as electrical insulation, corrosion resistance, and high temperature resistance. In addition, the production process of basalt fiber determines that less waste is generated, and there is little environmental pollution. After the product is discarded, it can be directly degraded in the environment without any harm, so it is a veritable green and environmentally friendly material. China has listed basalt fiber as one of the four major fibers (carbon fiber, aramid, ultra-high molecular weight polyethylene, and basalt fiber) for development, and has achieved industrial production. Basalt continuous fiber has been widely used in many fields such as fiber reinforced composite materials, friction materials, shipbuilding materials, thermal insulation materials, automotive industry, high-temperature filter fabrics and protection fields. Basalt fiber filter bags are said to be able to withstand high temperatures of more than 700 degrees, but the specific use is often controlled below 350 degrees. Above 350 degrees, deformation of the filter bag can be quickly observed. Basically, the filter bag can be judged by the high temperature damage .

High-temperature filter bags generally refer to filter bags with a temperature resistance of 200 degrees or more, which are divided into two categories: needle felt and fiberglass cloth. Needle felt high-temperature filter bags are further divided into glass fiber needle felt, fumex needle felt, P84 needle felt, PTFE needle felt, basalt needle felt, etc .; glass fiber cloth is further divided into graphite glass fiber cloth, Silicone oil glass cloth and expanded glass cloth. It is made of pure ultra-fine fiber filter cloth, finely melted or car-made, and has high temperature resistance. Product features: 1. The filter cloth is based on the thickness of the entire filter layer, which belongs to deep filtration; 2. The depth direction of the entire filter layer is formed by three-dimensional, loose and porous structure from fibers, from inside and outside from loose to dense, forming a gradient filter; 3. High pollution capacity, long filtration life, low pressure difference.
