Manufacturing method of instrument warm box

Abstract

Disclosed is a manufacturing method of an instrument warm box. Hot press molding is carried out on a sheet, and a main body of a box body and a main body of a box door are manufactured; the main body of the box body and the main body of the box door are put into corresponding foamed moulds respectively, and aluminum foil film layers are attached to the outer surfaces of core moulds of the foamed moulds; a foaming machine is used for manufacturing the box body with a warm layer and the box door with a warm layer through a polyurethane foaming technology, and then, the box body and the box door are assembled into a finished product; and the sheet is formed by sequentially arranging a C layer, a D layer and a C layer, wherein the C layers are short glass fiber reinforced unsaturated polyester resin composite material layers, and the D layer is a copper wire mesh layer with the wire diameter ranging from 0.3mm to 0.7mm.

Description

technical field [0001] The invention provides a method for manufacturing an instrument insulation box, which belongs to the field of instrument box manufacturing. Background technique [0002] The instrument insulation box is an important equipment to ensure that the on-site instrument can accurately display various data. The instrument box in the past technology is mainly made of stainless steel plate, carbon steel plate, and hand-laid glass fiber reinforced plastic; the engineering cost of the instrument box made of stainless steel plate bending and welding is very high. It is expensive, and the cost of heat preservation body processing, on-site construction and installation will also increase in the later stage, and the cost performance is low; the instrument box made of carbon steel plate has poor anti-corrosion performance, and local corrosion will cause a sharp drop in protection effect, and it is not resistant to acid and alkali corrosion. The scope of application in ...

[0002] The instrument insulation box is an important equipment to ensure that the on-site instrument can accurately display various data. The instrument box in the past technology is mainly made of stainless steel plate, carbon steel plate, and hand-laid glass fiber reinforced plastic; the instrument box made of stainless steel plate bending and welding is very expensive. It is expensive, and the cost of heat preservation body processing, on-site construction and installation will also increase in the later stage, and the cost performance is low; the instrument box made of carbon steel plate has poor anti-corrosion performance, and local corrosion will cause a sharp drop in protection effect, and it is not resistant to acid and alkali corrosion. The scope of application in the chemical industry is narrow; hand-laid FRP has good anti-corrosion properties to resist the harsh working environment on site, but hand-laid FRP products have low manufacturing efficiency, high manpower demand, unstable product quality, low mechanical strength, and poor thermal insulation performance , weak anti-aging performance, and prone to peeling damage after long-term use;
