Embodiment 1

[0035] According to an embodiment of the present invention, a kind of manufacturing process of flat steel paper is proposed, comprising the following steps:

[0036] Step 1: Carry out gelling treatment on the base paper for steel paper, specifically:

[0037] Under different climate and temperature conditions, zinc chloride solutions with different specific gravity of zinc chloride are used, and corresponding temperature requirements are set to impregnate and heat the base paper for steel paper to obtain base paper slurry;

[0038] When the temperature of the mixed solution of zinc chloride solution and base paper reaches the set requirements, according to the thickness design requirements of the flat steel paper, set the number of winding turns of the base paper slurry on the gelling machine, that is, when the thickness of the flat steel paper is designed When the requirements are high, the number of winding turns is relatively large; here, the corresponding relationship betw...

Abstract

The invention discloses a process for manufacturing flat vulcanized fibre. The process comprises the following steps of: performing gelling treatment on base paper by using solution of zinc chloride according to the preset temperature condition; cramming a plurality of gelled raw vulcanized fibre flat plates into grids to perform ageing treatment; performing desalination on the aged raw vulcanized fibre by using the solution of zinc chloride with degressive relative concentration; and cleaning, drying and shaping the desalted raw vulcanized fibre flat plates sequentially. The manufacturing process can overcome the defects of non-uniform shrinkage, easy deformation, easy cracking, low safety and the like in the prior art so as to realize the advantages of uniform shrinkage, no deformation, no cracking and high safety.

Description

technical field [0001] The invention relates to papermaking technology, in particular to a manufacturing process of flat steel paper. Background technique [0002] Steel paper is a kind of processed paper with high hardness, also known as indurated paper. Steel paper paper is hard, with excellent elasticity, wear resistance, corrosion resistance, heat resistance, mechanical strength, insulation performance and mechanical processing forming performance, and is very easy to apply to various mechanical processing, such as cutting, drilling , sticking, punching and grinding, etc. [0003] Steel paper is mostly used as heat insulation gaskets, insulating materials and other parts in the fields of electrical appliances, textiles, transportation, aviation and machinery. Its products include flat plates, rolls and tubes, etc. The advantages of lightness and beautiful appearance; for example, the specific gravity of aluminum is 2.7, while that of steel paper is 1.25±0.10, and the s...
