What is the difference between aluminum silicate needle blanket and other insulation materials?

An aluminosilicate needle blanket is an aluminum silicate material that is also a type of insulation material commonly found on the market. Can be used for insulation work in buildings. Let us compare the differences between aluminum silicate needle blankets and other insulation materials.

The aluminum silicate acupuncture blanket is a kind of thermal insulation material, which has strong effects of heat preservation, sound insulation and fire prevention. The aluminum silicate needle punching blanket is made of aluminum silicate material, and the aluminum silicate material has good low thermal conductivity, excellent thermal stability and chemical stability, and no binder and corrosiveness. Method for Producing Precipitated Aluminosilicate (P820) Precipitated aluminum silicate is obtained by using aluminum sulfate and sodium silicate as raw materials, and then reacting to form a precipitated aluminum silicate slurry, which is aged, filtered, dried, and air-jet pulverized to obtain a finished product.

The iron-free aluminum sulfate and sodium silicate are used as raw materials to prepare a solution of a certain concentration; the two liquid materials are respectively fed into the reaction tank with stirring and pre-added water and a certain additive at a certain flow rate, using steam Indirect heating, keeping the reaction temperature constant, by adjusting the flow rate of the raw material liquid, the system is maintained at a certain pH value for reaction, and then aging, filtering, washing, drying, and jet milling to obtain a qualified precipitated aluminum silicate product. The products manufactured by the complicated process have the characteristics that are not found in general products, and the aluminum silicate acupuncture blankets have a certain market position due to their wide use.
