Abstract
An anticorrosion pipe is made up of anticorrosion material through such technological steps as fixing anticorrosion material onto mould, inserting them into cleaned metal pipe, pressurizing while holding temp constant, depressurizing and demoulding. It is solidified at 70-80 deg.C and 6-8 MPa for 4-8 hrs. Its advantages are high adhesion between metal pipe and internal layer, low cost, and high refractory and mechanical performance. Its anticorrosion material may be thermosetting one.
Description
The present invention relates to a kind of manufacturing process of corrosionproof pipes, especially a kind of manufacturing process that adds glass fibre and thermosetting plastics corrosionproof pipes at inner wall of metal tube.
At present, most of corrosionproof pipes all is at inner wall of metal tube cover one deck thermoplastic pipes, and forms a kind of anticorrosion multiple tube.This method is a kind of machinery cover daraf(reciprocal of farad), require the smooth interior surfaces degree height of metal tube, otherwise cover draws difficulty, can only be the thermoplastic pipes with good plasticity with the method material therefor, and can not use thermosetting plastics, because the stressed easy fragmentation of thermosetting plastics.But the thermoplastic heat-resisting quantity is poor, and when temperature raise, mechanical performance descended very fast, and medium is fragile to its erosion damage aggravation, and between metal tube and the thermoplastic suspension area is arranged, also cracky.
Purpose of the present invention overcomes the deficiency of above-mentioned prior art and provides a kind of heat-resisting quantity good at what, and mechanical performance is strong, and metal tube is outer to combine firmly good seal, long service life, the manufacturing process of cheap corrosionproof pipes with anticorrosion internal layer.
Purpose of the present invention can reach by following measure, a kind of manufacturing process of corrosionproof pipes, and its feature is fixed on the mold at the what anti-corrosion material, penetrate then in the metal tube that has cleaned, moulding pressure is the 6-8 MPa, and keeping temperature is 70 ℃-80 ℃, solidified 4-8 hour, mould is removed in release.
Purpose of the present invention can also reach by following measure, and anti-corrosion material is thermosetting plastics and glass fibre, and thermosetting plastics is meant epoxy resin.
Compared with the prior art the present invention has following good effect: 1. this is simple for process, can directly make ginseng have the epoxy resin of glass fibre to be added in the inwall of metal tube, overcome the drawback that mechanical cover pulling method can only use the thermoplastic of heat resistance difference, make the metal tube skin combine firmly good seal with anticorrosion internal layer; 2. the corrosionproof pipes internal layer owing to this explained hereafter is thermosetting plastics and glass fibre, thereby this corrosionproof pipes corrosion resistance is strong, and mechanical performance is strong, and resistance to elevated temperatures is strong, and inner surface is smooth, long service life and cheap.
Description of drawings: figure is a kind of manufacturing process flow diagram of corrosionproof pipes
Describe the present invention in detail below in conjunction with accompanying drawing
Mold is that the rectangle pipe is with some iron rings outward by the rectangle pipe with some apertures, is connected with spring between iron ring and the rectangle pipe, and iron ring is with rubber tube outward, and rubber tube is surrounded by plastic sheeting outward and forms.Behind the glass fibre epoxy resin dipping, uniform winding penetrates together by the husky metal tube that cleans inwall of iron, fixedly mold on the mold plastic foil, sealed metal tube, water filling is pressurized to the 6-8 MPa then, and water overflows in mold rectangular pipe aperture, together is pressed onto plastic sheeting in the rubber tube and anti-corrosion material on the inner wall of metal tube, keeping temperature is 70 ℃-80 ℃, solidified 4-8 hour, rubber tube resets after the release, extracts mold out and promptly gets qualified products.
Claims (3)
1, a kind of manufacturing process of corrosionproof pipes, its feature is fixed on anti-corrosion material on the mold at what, penetrates then in the metal tube that has cleaned, is forced into the 6-8 MPa, keeps temperature at 70 ℃-80 ℃, and 4-8 hour hardening time, mould is removed in release.
2, according to the manufacturing process of the described a kind of corrosionproof pipes of claim 1, its feature is thermosetting plastics and glass fibre at the what anti-corrosion material.
3, according to the manufacturing process of the described a kind of corrosionproof pipes of claim 2, its feature is meant epoxy resin at the what thermosetting plastics.
