Embodiment Construction

[0014] The present invention will be further described below in conjunction with embodiment.

[0015] The present embodiment provides the manufacture method of low-temperature calcined mica paper, and the method comprises the following steps:

[0016] The mica material is calcined at low temperature, and the mica material calcined at low temperature is screened with a 3-mesh sorting sieve to obtain mica essence of 3 mesh or more, and the fine material obtained through the screening is cleaned, and every 50kg is divided into two washes to achieve water quality It is clear that the cleaned mica material is evenly spread on the conveyor belt in a straight line. The conveyor belt is 20 materials long and runs at a speed of 7 meters per minute.

[0017] (1) The mica material conveyed by the conveyor belt is broken into pulp by hydraulic pulping equipment, and the supplementary water for pulping is controlled at 20-25 cubic meters. The broken mica material accounts for more than 50...

Abstract

The invention relates to a method for manufacturing mica paper by calcining a mica material at a low temperature. The main method comprises the following steps: (1) calcining the mica material at the low temperature; (2) screening and washing the mica material which is calcined at the low temperature in step (1); (3) crushing and pulping a refined material which is obtained by screening and washing in step (2); (4) delivering the crushed pulp material to a refined pulp tank by a pipeline, and uniformly stirring; (5) allowing the mica pulp material to pass through a circular mesh cage with good drainage capacity, uniformly adsorbing mica pulp pieces on coarse cotton cloth of a paper maker, and extruding the mica pulp pieces in a main presser and a secondary presser by a uniform linear pressure, thus obtaining basically-shaped mica paper; and (6) finally drying the mica paper in drying cylinders at a high temperature, and allowing the mica paper to pass through an upper drying cylinder and a lower drying cylinder, thus obtaining various pieces of mica paper of different thicknesses. The method disclosed by the invention solves the technical problems that the mica paper has low compression strength, low tensile strength, unstable glue penetration time, unstable air permeability and the like, and has the advantages of high compression strength, high tensile strength, stable glue penetration time and stable air permeability.

Description

technical field [0001] The invention relates to the field of mica material processing, in particular to a method for manufacturing mica paper. Background technique [0002] The traditional production method of mica paper is that the mica material is screened and cleaned, and then directly made by hydraulic pulping. The mica paper produced by this method has low compressive strength, low tensile strength, gluing penetration time and air permeability are unstable, so it cannot be used to produce high-strength mica boards, mica tapes, special-shaped parts, electric heating films, etc. product. Contents of the invention [0003] The purpose of the present invention is to solve the above existing technical problems and provide a mica paper production method with high compressive strength, good tensile strength, stable gluing penetration time and air permeability. [0004] 1. a kind of manufacture method of low temperature calcined mica paper, described production method compr...
