example 1

[0031] Use a glass fiber blanket to impregnate water glass solution with a concentration of 5%-20%, and then use vacuum suction to make the amount of water glass solution 3-6 times the weight of the glass fiber blanket to obtain a glass fiber wet felt product. It is mainly used It is used for thermal insulation on the surface of thermal equipment whose surface temperature is not higher than 500°C.

example 2

[0033] Use 1260 ceramic fiber blanket to impregnate silica sol solution or 5%-20% aluminum sol solution with a concentration of 5%-30%, and then use vacuum suction to make the amount of inorganic binder 3-6 times the weight of the blanket, that is, Ceramic fiber wet felt products, which are mainly used for surface heat insulation of thermal equipment with a surface temperature not higher than 1200°C.

example 3

[0035] Use high-alumina ceramic fiber blanket, zirconium-containing ceramic fiber blanket or chromium-containing ceramic fiber blanket to impregnate silica sol solution or 5%-20% aluminum sol solution with a concentration of 5%-30%, and then use vacuum suction to make the inorganic binder The amount is 3-6 times the weight of the blanket, that is, ceramic fiber wet felt products, which are mainly used for surface heat insulation and protection of thermal equipment with a surface temperature not higher than 1350°C.

Abstract

The invention relates to a fireproof heat insulation wet felt, which comprises an inorganic fiber blanket and an inorganic adhesive, wherein the weight ratio of the inorganic fiber blanket to the inorganic adhesive is 1:3-6. The inorganic fiber blanket is one or mixture of more of 1260 ceramic fiber blanket, high-aluminum ceramic fiber blanket, zirconium-containing ceramic fiber blanket, chromium-containing ceramic fiber blanket, polycrystalline mullite fiber blanket, glass fiber blanket and high-silica fiber blanket; and the inorganic adhesive is one or composite solution of more of water glass, silicon sol, aluminum sol, aluminum phosphate, aluminum sulfate and aluminum potassium sulfate. The wet felt can be randomly folded and bent in any direction, is wrapped, wound and stick togetherwith the shapes of equipment and parts during construction, and particularly can remarkably improve the construction efficiency during construction of a special-shaped part or a pipeline part or the like. The wet felt is formed by soaking the inorganic fiber blanket into the inorganic adhesive, so the wet felt is very easily bent, has good wet strength, and can be cut into various shapes and sizes or subjected to compression molding.

Description

technical field [0001] The invention relates to a wet felt and its production process, in particular to a fire-resistant and heat-insulating wet felt and its production process. Background technique [0002] Inorganic fiber blankets are widely used in various industries as the heat-resistant heat-resistant protective layer on the hot surface and the thermal insulation layer on the cold surface of thermal equipment. It is pasted to the inner or outer surface of thermal equipment. When the curvature of the equipment surface is complicated, the construction is more difficult. And the wet felt of the present invention is very good for construction, it can be folded and bent in any direction, wrapped, wound and pasted according to the shape of equipment and parts during the construction process, especially used in special-shaped or pipes and other parts During construction, the construction efficiency can be significantly improved. Wet felt is made of inorganic fiber blanket im...
