Abstract

In order to solve the problem of that the bad production maintenance of the antiseptic property of current gas piping is of high cost, the present invention provides a kind of antiseptic finish methods of gas piping, include the following steps：Derusting；After processing of rust removing smearing asphalt primer is carried out in 1 hour；Pipeline is heated, gas piping temperature controls 190 DEG C~210 DEG C after heating, then spraying corrosion resistant coating；Finishing coat is smeared, finishing coat uses polyurethane anti-corrosion paint.The antiseptic finish method of gas piping of the present invention is used and is first primed, clinkering type ring oxygen powder bed is further added by, finally smears the mode of finishing coat, main function is being capable of anti-corrosion, extraneous more complicated soil environment and climatic environment are resisted, the ability with extremely strong weatherability and resistant to mechanical damage.

Description

A kind of pipeline impregnation
Technical field
The present invention relates to pipeline processing technical field more particularly to a kind of antirust manufacture fields of pipeline.
Background technology
In the prior art, common pipeline corrosion protection uses galvanized pipe, and coating steel pipe quality is hard, rigidity is big, toughness is high, It is firm reliable, it is widely used；For coating steel pipe compared with existing various plastic conduits, major defect shows that inner wall of the pipe passes through Long-term flow is impregnated, and can generate corrosion, and inner wall of the pipe gradually becomes loose, uneven, increase water resistance, and more seriously Inner wall corrosion causes water to contain iron rust；Then there are many engineering plastics pipes, plastic conduit has dead weight compared with conventional steel Gently, it is corrosion-resistant, service life is long, small flow resistance, it is energy saving the advantages that, it is but the pressure resistance of plastic conduit, impact resistance energy, resistance to It is all more far short of what is expected than conventional steel that high/low temperature changes performance repeatedly, therefore, how to accomplish not only can pressure resistance but also can antirust be this field skill Art personnel's problem encountered.
Invention content
In order to solve current pipeline not only can pressure resistance but also can antirust demand, the present invention provides a kind of pipeline impregnation, Its purpose is to provide a kind of corrosion-resistant, non-corrosive, tube wall are smooth, and it is upright and outspoken be unlikely to deform, be heat-resisting, pressure-resistant pipeline.
A kind of pipeline impregnation of the present invention, includes the following steps：
S1：Derusting, pipeline is immersed in pickle and is derusted；
S2：Cleaning, and it is dry, and cleaning solution uses a concentration of 15~20% saponification liquor；
S3：Leaching modeling carries out pipeline to be heated to 100 DEG C~150 DEG C, carries out rotational moulding processing, the rotational moulding material changes for polyolefin Property material；
S4：Heat preservation, the pipeline after being moulded to leaching are carried out in 80 DEG C~120 DEG C range inside holding 5min~10min；
S5：Leaching modeling pipeline after heat preservation is naturally cooled to room temperature, then detects whether qualification by cooling detection.
Further, the pickle volume proportion be hydrochloric acid 40%, phosphoric acid 30%, triethanolamine 7%, sulfuric acid 11%, Lauryl sodium sulfate 8%, remaining adds to 100% with distilled water.
Further, saponification temperature control is at 100 DEG C~120 DEG C in second step, 3~5min of time.
Further, the polyolefine modified material Ingredients Weight proportioning includes：15 parts of polypropylene, 12 parts of polyethylene, carbon Sour 17 parts of calcium, 3 parts of organo-silicon compound.
The present invention forms plastic anti-corrosion layer using the method for leaching modeling in pipeline surfaces externally and internally, has high mechanical strength, pressure-bearing Ability is strong, and electrical apparatus insulation ability is outstanding, and appearance surface hardness is high and smooth, and friction coefficient is small, and water absorption rate is low, use temperature range is big The characteristic for waiting composite metal plastic pipes intrinsic.
Specific embodiment
A kind of pipeline impregnation of the present invention is used as basic pipeline in actual use, using ordinary carbon steel pipe, in this reality It is as follows to apply specific processing method in example：
S1：Derusting, pipeline is immersed in pickle and is derusted；In the present embodiment, pickle volume proportion is hydrochloric acid 40%, phosphoric acid 30%, triethanolamine 7%, sulfuric acid 11%, lauryl sodium sulfate 8%, remaining is added to distilled water 100%；The addition of restrainer neither influences dispelling, and can guarantee product matrix quilt as few as possible for metal surface rust staining Acid solution corrodes.
S2：Cleaning, and it is dry；Pipeline after derusting is put into a concentration of 15~20% saponification liquor and is carried out at saponification Reason, saponification temperature are controlled at 100 DEG C~120 DEG C, 3~5min of time, clean the residual liquid after pickling, while prevent pipeline from giving birth to Rust.
S3：Leaching modeling carries out pipeline to be heated to 100 DEG C~150 DEG C, carries out rotational moulding processing, in order to improve antiseptic property, rolling Moulding material is polyolefine modified material, to improve the adhesive force of coating and base material, polyolefine modified material ingredient in the present embodiment Weight proportion includes：15 parts of polypropylene, 12 parts of polyethylene, 17 parts of calcium carbonate, 3 parts of organo-silicon compound.
S4：Heat preservation, in order to which to leaching modeling layer curing, the pipeline after being moulded to leaching is carried out in 80 DEG C~120 DEG C range inside holdings 5min~10min.
S5：Leaching modeling pipeline after heat preservation is naturally cooled to room temperature, qualification is then detected whether, in this reality by cooling detection It applies and predominantly detects whether leaching modeling pipe surface soaks modeling uniformly and whether leaching modeling thickness is uniform in example.
The present invention forms plastic anti-corrosion layer using the method for leaching modeling in pipeline surfaces externally and internally, has high mechanical strength, pressure-bearing Ability is strong, and electrical apparatus insulation ability is outstanding, and appearance surface hardness is high and smooth, and friction coefficient is small, and water absorption rate is low, use temperature range is big The characteristic for waiting composite metal plastic pipes intrinsic；And, suitable for hot water pipeline, made using polyolefine modified material coating in the present invention With the plastic coated composite steel pipe of the coating, the larger temperature difference alternately variation occasion is adapted to.
Although giving detailed description and explanation to the specific embodiment of the present invention above, it should be noted that We can be according to the present invention conception various equivalent changes and modification are carried out to the above embodiment, generated function is made It, should all be within protection scope of the present invention during with the spirit still covered without departing from specification.
