Aluminum silicate board production process
Ordinary aluminum silicate board is made of coke sapphire as the main raw material, in the melting and silking (adding proper amount of binder during the silking process),
Curing chamber curing, cutting and other processes. The whole process is automatically controlled by PLC, and the product is formed at one time.
Main specification density: 80-140kg/m3 Thickness: 15-100mm Width: 400, 600, 1200mm Length: Can be customized according to user requirements.
Product characteristics 1, low thermal conductivity, low heat capacity.
2. Excellent thermal shock resistance and thermal stability.
3. High compressive strength and good toughness.
4. Excellent machining performance.
Application 1, industrial furnace wall lining, furnace door and top cover sealing.
2. Fire protection and heat insulation of construction projects and fire doors.
3. Insulation and heat insulation of high temperature equipment such as electric power and chemical industry.
4. Ship bulkheads, decks, offshore oil rigs.
