Classification and characteristics of aluminum silicate needle blanket

The aluminum silicate needle-punched blanket is a kind of heat-insulating refractory material which is made of aluminum silicate as raw material and is made by electro-acoustic furnace technology and special aluminum silicate long fiber needle-punched. Aluminum silicate needle blankets are often used in various fields such as chemical industry, construction industry, electronics industry, aerospace industry, military industry, air conditioning refrigeration.

First, the classification of aluminum silicate needle blanket:

1. According to different production processes, it can be divided into silk needle punching blanket and jet needle punching blanket;

2, according to different raw materials and formulations can be divided into: ordinary (STD), high purity (HP), high aluminum (HA), zirconium aluminum, standard, zirconium (ZA).

Second, the characteristics of aluminum silicate needle blanket:

The aluminum silicate acupuncture blanket is made of high-quality coke gypsum melted at a temperature of more than two thousand degrees Celsius and solidified with other additives. It has many special properties, such as good extensibility, strong shock resistance, light weight and heat insulation. Excellent, strong stability, no deformation at high temperatures of several thousand degrees.
