Composition of AZS tamping material
AZS tamping material is made from oxidizing fused AZS particle and fine powder with a certain ratio, and added with proper amount of adhesive. It is half dried and formed as monolithic refractory material by tamping with high strength.
In the process of use, a certain concentration of phosphoric acid or aluminum dihydrogen phosphate can be adopted as the additive. In some conditions, it is also possible to add with some coagulants.
Application
AZS tamping material is mainly applied in sealing the bottom and other parts of glass furnace.
Characteristics
(1) High resistance of high temperature and compressive strength.
(2) Small thermal expansion and shrinkage
(3) Strong corrosion resistance of glass solution
(4) Excellent thermal shock resistance
(5) Low thermal conductivity at high temperature
(6) Stable chemical property, and it can not react with molten metal
(7) Weak tendency of bubble precipitation
