Abstract
A process for preparing the reinforced MC nylon pipeline used as anticorrosion pipeline includes such steps as heating caprolactam in a smelting furnace, vacuum treating, adding additive, homogenizing, reaction, and centrifugal casting. The material has stable physical properties, acid and alkali resistance and corrosion resistance, and is suitable for industries such as petroleum, chemical engineering, mines and the like and all environments with corrosive gas and liquid.
Description
The present invention relates to the manufacture method that anti-corrosion pipeline strengthens the MC nylon pipeline.
Along with industrial development, the pipeline of department's production runs such as chemical industry, oil, mine because corrosion causes a large amount of losses of metallic conduit, and influences manufacturing schedule.Thereby, develop a kind of corrosion resistant pipeline and seem very important.At present application number is that 91101934.0 " cladding technique of corrosion-resisting clad pipe " and application number are the patent application of 92100118.5 " manufacture method of steel-plastics composite pipe ", is at the lining inner surface of tubes with plastics bushing pipe, has solved the corrosive pipeline problem to a certain extent.But its weak point is also arranged, the one, this pipeline appearance is still exposed between the environment of the gas of corrosion, liquid, can not thoroughly solve by the erosion problem.The 2nd since steel to mould the coefficient of expansion inconsistent, although adopt raising machine that the steel pipe inwall is rolled out pit and burr one by one, put plastic liner again, still have the leakage of pipeline chemical medium.The 3rd, manufacturing process is more numerous and diverse.
The objective of the invention is to provide the ideal conduit of a kind of new and one-time formed conveying corrosivity gas, liquid to strengthen the manufacture method of MC nylon pipeline in order to overcome above-mentioned weak point.Make it to replace metal tube, composite metal plastic pipe fully, improve the pipeline operational reliability.
Description of the present invention is as follows, MC nylon be caprolactam under base catalyst and caproyl amine co-catalyst existence condition, ring-opening polymerisation forms.Strengthening the MC nylon pipeline, to adopt caprolactam be raw material heating and carry out application of vacuum, add additive reaction under homogenising is handled again in molten device, pours into then in the mould of preheating and carry out the spun casting polymerization forming.Its prescription: with the caprolactam is raw material, glass fiber powder 12 ‰, di-iron trioxide 10 ‰, molybdenum trisulfide 5 ‰, coupling agent 0.5 ‰, NaOH 3 ‰, toluene di-isocyanate(TDI) 10 ‰.------------mould gives heat, and------moulding---is incubated---demoulding---goods heat treatment---machine tooling---finished product to the technological process of production: caprolactam-hot melt in spun casting in the homogenising processing to add additive in application of vacuum.
Embodiment, strengthening the MC nylon pipeline is to be primary raw material with the caprolactam, in molten device, be heated to 160-165 ℃ and carry out application of vacuum, add additive (12 ‰ glass fiber powders after 40 minutes, 10 ‰ di-iron trioxides, 5 ‰ molybdenum bisuphide, 0.5 ‰ coupling agent, 3 ‰ NaOH, 10 ‰ toluene di-isocyanate(TDI)s) carry out the homogenising reaction treatment after, pour in the centrifugal casting machine the material in the molten device in the mould of preheating centrifugal casting moulding, be incubated the demoulding after 20 minutes, again with the heat treatment 24 hours in being added with 100 ℃ hot water of liquid medicine of pipeline dip, make its physical property further stable, process at flange end with lathe then, make it smooth smooth, boring circular hole on the flange as required, connect so that install, promptly become and strengthen the MC nylon pipeline.This method is applicable to the straight tube of different bores, various bend pipe and threeway, four-way, reducer pipe.
The present invention is because the employing caprolactam is a raw material, add other additive, at scientific and rational technological process of production compacted under, make its physical property very stable, not only have acid and alkali-resistance, corrosion resistance characteristic, but also have the heavily fortified point of metallic conduit and toughness that metallic conduit can not be compared and in light weight, wear-resistant, solved in corrosion-prone problems of industry production other pipeline in service such as oil, chemical industry, mines.
Claims (3)
1, a kind of anti-corrosion pipeline strengthens the manufacture method of MC nylon pipeline, it is characterized in that: strengthening MC nylon pipeline employing caprolactam is that raw material heats and carry out application of vacuum in molten device, add additive reaction under homogenising is handled again, pour into then and carry out the spun casting polymerization forming in the preheated mold.
2, the manufacture method of enhancing MC nylon pipeline according to claim 1, it is characterized in that prescription is a raw material with the caprolactam, glass fiber powder 12 ‰, di-iron trioxide 10 ‰, molybdenum bisuphide 5 ‰, coupling agent 0.5 ‰, NaOH 3 ‰, toluene di-isocyanate(TDI) 10 ‰.
3, the manufacture method of enhancing MC nylon pipeline according to claim 1 is characterized in that the technological process of production is: caprolactam, and---------------mould gives heat, and------moulding---is incubated---demoulding---goods heat treatment---machine tooling---finished product to hot melt in spun casting in the homogenising processing to add additive in application of vacuum.
