Product Description
Fiber blanket
Fiber blanket is the use of acupuncture in particular to strengthen the process from fiber blanket, the process does not contain any binders or other ingredients, an enhanced needle craft a corresponding increase in the extent and fiber woven carpet delamination performance, without affecting the its flexible at the same time to have good tensile strength. Installation is simple, greatly accelerated the pace of construction lining. In addition to hydrofluoric acid, phosphoric acid and alkali, the product from most other chemical erosion.
Features:
Low thermal conductivity, easy processing, installation, low heat capacity, good sound absorption properties, excellent chemical stability, resistance to air erosion, thermal shock, corrosion-resistant, elastic fibers, high temperature shrinkage
Application:
Mainly used as raw material for the module, compressed folded blanket made ??by folding module M.A metallurgical machinery: furnace, heat treatment furnace, ladle insulation cover
Second, the petrochemical industry: conversion furnace, atmospheric and vacuum furnace, cracking furnace, flue
Third, ceramics porcelain: roller kiln, shuttle kiln, tunnel kiln
Fourth, other: various types of industrial furnaces, and hot air pipes, high temperature equipment such as high-temperature furnace lining.
