How to Identify High-Quality Polycrystalline Mullite Fiber

Pretend pretend to user to user the user the information sent back by the close paragraph of time, refractory company according to our sales department, with the high temperature refractories fiber industry boom will continue to improve, the market began to have some production capacity, quality assurance, no after-sales service "three noes" manufacturers or companies, through some of the heat treatment of high temperature refractory ceramic fiber knowledge understanding is not very comprehensive, through some of the heat treatment of high temperature refractory ceramic fiber application of risk, safety awareness is relatively low, through the network propaganda means low price induced heat treatment, the tolerance to low temperature resistant to high temperature, the poor quality of the products high quality, sold to heat treatment of users. High temperature fiber (polycrystalline mullite fiber, alumina fiber production process control requirements are relatively high, which glue: sol gel, and fiber: hot air temperature, pressure, speed, drying, heat treatment, hot processing temperature and time process data must control precision, or after use will appear fiber lined with severe refractory brick for sale contraction, powder, cracks and peeling off, resulting in the fire channelling. It not only damages the industrial furnace equipment, also caused the safety problems in industrial furnace, to heat treatment user brought no small loss.
Refractory fibre is a kind of a white fibrous lightweight refractory material, if not a professional general visual it is difficult not the quality of the material and high temperature levels, part of the "three noes" of the manufacturers or companies violate integrity management

The difference between ceramic fiber paper and ceramic fiber cloth

Ceramic fiber paper and ceramic fiber cloth are refractory insulation materials, can be used to heat insulation, how to better distinguish between ceramic fiber paper and

1.Building material industry,kiln,heating equipment and the inwall of high-temperature pipe line2.Chemical industrial high temperature of reaction equipment inwall3.Power plant ,gas turbine engine and heat insulation of unclear power4.The fire proof of high-rise building5.Used to make gasket6.High-temperature filter material

ceramic fiber cloth, according to the accumulation and experience, can be in several aspects to distinguish:

1 appearance. ceramic fiber felt cloth has a clear grid like, ceramic fiber paper is very little, and even no grid.
2 density. Ceramic fiber paper is greater than the density of ceramic fiber cloth.
3 thickness. Ceramic fiber paper high insulating brick is the most thin can be done 0.5mm, ceramic fiber paper can not do so thin, generally the most thin also has 2mm.
4 stand. Ceramic fiber paper can be like in our life that can be placed on the A4 paper, mold, stand up. refractory company Ceramic fiber cloth is like our life with cloth, very soft, does not

have to stand.
5 tear resistance. The toughness of ceramic fiber paper is not good with ceramic fiber cloth.
