Description
Technical field
The present invention relates to a kind of external layer butt fusion type plastic stainless-steel composite-tubes material, also relate to a kind of manufacture method of this composite pipe.
Background technique
At present, common civil buildings common employing PE or PP-R pipe carry out potable water conveying, only have high-grade hotel and Gongjian's project just can use not only health but also the sanitation-grade stainless steel pipeline of safety.If ordinarily resident can be allowed also to use not only health but also the stainless steel pipeline of safety, reduce the installation cost of product again, market does not still solve feasible product and technique.
Due to the particularity of stainless steel connection request, the complex process generally adopted, holistic cost is caused to increase, its mounting process cost is higher than the cost of tubing own, in existing life staying idle at home, generally adopt 304 stainless steel pipeline, if directly outside exposed, also by chlorion in being lived to the erosion on its surface, time one length causes pipe perforation to leak, and haves much room for improvement.
Further, this external layer butt fusion type plastic stainless-steel composite-tubes material does not commercially occur, also needs the manufacture method researching and developing this composite pipe a kind of.
Summary of the invention
The object of the invention is, in order to provide a kind of external layer butt fusion type plastic stainless-steel composite-tubes material, effectively to prevent percolating water, avoiding the secondary pollution reducing potable water in pipeline.
For achieving the above object, technological scheme of the present invention is:
External layer butt fusion type plastic stainless-steel composite-tubes material, is characterized in that: comprise pipe in sanitation-grade stainless steel, the outside of pipe is provided with plastic tube in stainless steel, in described plastic tube and described stainless steel, be provided with heat-fusing glue layer between pipe.
Further, described plastic tube is PE pipe or PP-R pipe.
Beneficial effect of the present invention: the present invention adopts the Stainless Steel Tube of sanitation-grade, plastic tube is connected by heat-fusing glue layer in the outside of stainless-steel pipe, and plastic tube adopts PE pipe or PP-R pipe, like this in pressure rating, usage requirement, apparent size meets relevant criterion requirement completely, can directly to manage with common PE or PP-R pipe carries out installation and is connected, reduce mounting process and the difficulty of whole composite pipe, also just installation cost is reduced, also improve the reliability of the percolating water of Stainless Steel Tube simultaneously, isolate the contact of plastic pipe inner wall 95% surface and potable water simultaneously, reduce the secondary pollution of potable water.
Object two of the present invention, is the manufacture method providing this external layer butt fusion type plastic stainless-steel composite-tubes material a kind of, reduces after-cost.
A manufacture method for external layer butt fusion type plastic stainless-steel composite-tubes material, is characterized in that:
Comprise the following steps:
The first step, by special tractor conveying sanitation-grade Stainless Steel Tube, carry out preheating through heating cabinet, the temperature of described heating cabinet is at 300-500 DEG C.
Second step, by the first mould, to sanitation-grade stainless steel pipe surface coating thermosol, described first die temperature is at 220-250 DEG C;
3rd step, by the second mould, to the sanitation-grade Stainless Steel Tube outer surface coating plastic skin again of coating thermosol, described second die temperature is at 220-250 DEG C;
4th step, through air-cooled sleeve surface precooling;
5th step, then enter immersion type cooler bin;
6th step, finally carries out second time traction, cuts finished product.
As from the foregoing, present invention process is do not have in prior art, and manufacturing efficiency is high, and cost is low, and technological design is reasonable.
Further, described first mould comprises inner formation for the mould of sanitation-grade Stainless Steel Tube by passage, and connects thermosol extruder by flow-path tube, described thermosol extruder technological temperature 200-300 DEG C of skill temperature 200-250 DEG C.
Further, described second mould comprises inner formation for the mould of sanitation-grade Stainless Steel Tube by passage, and by flow-path tube connecting plastic extruder.
Further, described air-cooled sleeve pipe is connected with blower fan.The present invention by blower fan at a high speed air-supply to cooling collar, reach the effect that the blowing precooling of plastic tube surface is stable, the front globule of avoiding soaking sticks in plastic tube surface and produces small rut.
The special tractor related in the present invention, heating cabinet, the first mould, the second mould, thermosol extruder, plastic extruder and air-cooled sleeve pipe and blower fan, be all prior art, that commercially can buy arrives, and is not repeating at this.
First the present invention will pull whole sanitation-grade Stainless Steel Tube by special tractor, heat being in inner sanitation-grade Stainless Steel Tube by heating cabinet, sanitation-grade Stainless Steel Tube is made to enter coating thermosol in the first mould, the now prior extruding and hot melting glue of thermosol extruder, flow into the first mould inside by flow-path tube, make sanitation-grade stainless steel pipe surface carry out even coating hot-melt adhesive.When by the sanitation-grade Stainless Steel Tube of even coating hot-melt adhesive, enter the second mould inside, plastic extruder extrusion plastic, be coated on the outer wall of the sanitation-grade Stainless Steel Tube of even coating hot-melt adhesive by the second mould, both realizations bond together, now temperature is high, be unfavorable for depositing immediately, so through air-cooled sleeve surface precooling, then enter immersion type cooler bin, realize cooling rapidly, can deposit immediately or carry.
In order to explain technological scheme of the present invention further, below by specific embodiment, the present invention will be described in detail.
