Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] Such as figure 1 , figure 2 As shown, the preparation process of aluminum silicate fibrous fiberboard is to use resistance furnace to melt raw materials. When the molten pool meets the process requirements, the molten liquid will form a stable stream through the orifice, and the filaments will be formed into fibers by spinning rollers. Chemical sizing, so that the binder is evenly distributed on the fiber, and then the cotton is settled and collected by the cotton collector, and then enters the drying oven to be solidified and formed, and finally cut and formed according to customer needs. Specific steps are as follows:,

[0027] Step a, resistance furnace melting material: select raw materials according to product process requirements or customer needs, and can produce different types of fiberboards. Fiberboards can be divided into ordinary fiberb...

Abstract

Disclosed is a manufacturing method of an aluminum silicate thread throwing fiber board. The method comprises the steps that raw material coal gangue and flint clay are mixed proportionally and placed into a resistance furnace to be molten, molten liquid flows out strand by strand through a drainage pipe at the bottom of the resistance furnace and falls on a thread throwing machine to be condensed into fiber, an adhesive spraying mechanism sprays out adhesives in a fog shape and uniformly coats the surface of the aluminum silicate thread throwing fiber with the adhesives, the fiber is blown to a cotton collection machine through an annular wind belt to be subjected to negative pressure collection to form cotton, and the aluminum silicate thread throwing fiber board is manufactured through the steps of curing, cutting and the like. The production technology is simple, and the automation degree is high. The manufactured aluminum silicate thread throwing fiber board has the smooth and flat surface, high physical strength and good thermal insulation property.

Description

technical field [0001] The invention relates to the technical field of heat insulation materials, in particular to an aluminum silicate ceramic fiber product and a preparation method. Background technique [0002] Aluminum silicate ceramic fiber is a kind of fibrous light refractory and heat insulation material developed in the construction industry in the early 1960s. It is a new type of industrial insulation material, and its structure belongs to amorphous (glassy) fiber. . The traditional production process of aluminum silicate fiberboard is mixing→melting→blowing / spinning→cotton collection→cotton selection→solidification→cooling→cutting→packaging. Generally, it is made by electric arc blowing process, that is, hard clay clinker or industrial alumina powder and silica powder are used as raw materials, melted in an electric arc furnace, blown into fibers by compressed air, and then formed by aluminum silicate Ceramic fibers are processed into blankets, felts, boards, p...
