The standard aluminum silicate wool is made from the chamotte of hard clay blown into floccose fiberafter melted in electric oven. High aluminous aluminum silicate wool is made from the mixture of high purity alumina and silica powders blown into floccose fiber after melted in electric oven.
Production Technique
1. The standard aluminum silicate wool is made from the chamotte of hard clay blown into floccose fiberafter melted in electric oven.
2. High aluminous aluminum silicate wool is made from the mixture of high purity alumina and silica powders blown into floccose fiber after melted in electric oven.
3. Zirconic aluminum silicate wool is made from the mixture of high purity alumina, silica and zircon powders blown into floccose fiber after melted in electric oven.
4. Cemented aluminum silicate wool is made by adding a certain proportion of refractory cementing agent in the course of blowing.
Product Characteristics
1. Low thermal conductivity, low thermal capacity.
2. Excellent thermal stability, chemical stability and sound absorption.
3. Containing no corrosive material.
Application
1. Sandwich filling for equipment.
2. As raw material for vacuum forming products.
3. Fibrous casting material, daubing material, coating material, fibrous paper, etc.
4. Aluminum silicate wool containing cementing agent is the best material for making boards, pipe shells and irregular components with dry process.
