Inorganic fireproof plate and forming equipment thereof

Abstract

The invention discloses an inorganic fireproof plate and forming equipment thereof. The inorganic fireproof plate is of a multilayered combination frame structure, and comprises a bottom frame layer,a middle frame layer and a surface frame layer which are sequentially arranged from bottom to top. The forming equipment comprises stirring units and a rolling unit, the stirring units are arranged above the rolling unit, each stirring unit comprises a dry-state raw material stirring machine, a wet-state raw material stirring machine and a buffer stirring machine which are sequentially connected in series, and the rolling unit comprises a rack, a bottom frame layer roller wheel set, a middle frame layer roller wheel set, a surface frame layer roller wheel set and glass fiber gridding cloth guiding wheels, wherein the bottom frame layer roller wheel set, the middle frame layer roller wheel set and the surface frame layer roller wheel set are sequentially arranged on the rack. According to the inorganic fireproof plate and the forming equipment thereof, the density of each layer of a produced product can be stably mastered, so that the stirring effect on raw materials is achieved simultaneously in the rotating process of the raw materials, the state that the raw materials are evenly stirred is ensured, meanwhile the situation that light inorganic foam materials are not extruded and broken is guaranteed, and therefore the design performance requirements of the product are met.

Description

technical field [0001] The invention belongs to the technical field of inorganic fireproof materials, and relates to an inorganic fireproof board and forming equipment thereof. The inorganic fireproof board has a multi-layer composite frame structure and is mainly used in the field of wall fireproof materials. Background technique [0002] With the innovation of wall materials and the implementation of building energy-saving policies in our country, the development and application of energy-saving building materials have been widely valued. Commonly used fireproof boards for ceilings and partition walls in building materials include fiber cement boards, gypsum boards, glass magnesium boards and resin composite boards, etc. Among them, glass magnesium boards have defects such as moisture absorption and halogen return, deformation and strength reduction, and corrosion of steel structures. , is only suitable for the application of various fireproof linings; gypsum board loses s...

AI Technical Summary

Problems solved by technology

[0004] In the production and processing of traditional fireproof boards, a set of rollers is used to press the raw material out to a certain thickness, and then the next set of rollers is used to compact it; this production method has been used for many years, but there are still deficiencies. , mainly manifested in: when there are light or foamed materials in the raw material, due to insufficient fluidity or compression resistance, such materials are easily broken during rolling, and various properties that should be lost in design are lost.
