Polycrystalline mullite fiber is a type of ultra light high temperature refractory fiber cotton, which has the Al2O3 72% - 75%, the service temperature is 1500-1700 ℃.
Polycrystalline Mullite Fiber Blanket is a fiber blanket made by using a specially reinforced needle punching process, which does not contain any binders or other components. The reinforced needle punching process correspondingly improves the interweaving degree of fibers and the anti layering performance of the blanket, while not affecting its flexibility, but also giving it good tensile strength. The installation method is simple and greatly accelerates the construction speed of the furnace lining. Except for hydrofluoric acid, phosphoric acid, and strong alkalis, the product is not subject to corrosion by most other chemical substances.
Product features:
Good fiber elasticity and low high-temperature shrinkage
Low thermal conductivity
Easy to process and install
Low heat capacity
Good sound absorption performance
Excellent chemical stability
Resistance to wind erosion
Resistance to thermal shock and corrosion
Product application:
Mainly used as raw material for modules, the blanket is folded and compressed to make a folding module M
Metallurgical machinery: heating furnace, heat treatment furnace, ladle insulation cover
Petrochemical industry: conversion furnace, atmospheric and vacuum furnace, cracking furnace, flue
Ceramic electric porcelain: roller kiln, shuttle kiln, tunnel kiln
Other: various industrial furnaces, as well as hot air pipelines, high-temperature equipment, high-temperature kiln lining, etc.
