Fitly it is wrapped on straight tube mould, after winding 1 layer of ring, 1 helical layer, 1 layer of ring, after winding is finished, pipeline is heated to
60 DEG C solidify 20 minutes；C) external protection coating process：One layer of preferable polyurethane resin of water-tight corrosion-proof is brushed outside pipeline.
Preferably, the specific steps that one layer of preferable polyurethane resin of water-tight corrosion-proof is brushed outside pipeline are also wrapped
Include, add abrasive powder in resin and aluminium powder is used as filler.
Preferably, the mass ratio of the abrasive powder and the aluminium powder is 3:4.
Preferably, product quality is also included after methods described to detect.
Preferably, the specific steps of the product quality detection include, Appearance Visual, see that whether smooth its pipe internal surface is flat
It is whole, without cracking influential on performance, layering, pin hole and bubble；Tube end should be concordant, arris impulse- free robustness, outer surface without
Open defect.
Beneficial effects of the present invention：
A kind of glass reinforced plastic pipe end production process that the present invention is provided, with higher intensity, rigidity, for agricultural resource
Develop, increase farmers' income with positive effect.
Embodiment
Technical solution of the present invention is described in detail below.
(1) preparatory process
A, equipment debugging.Conscientiously check whether equipment operation and working position normal first, be important to it is careful check resin-
Whether curing agent bi-component pump has clogging, between match whether reach design requirement；Ensure system lining, winding, repair, take off
The stable and operating accuracy of the equipment such as mould；
B, cleaning mould.It is required that die surface will accomplish that surface is put down without recessed, dust, debris and other attachments, mould is cheated
It is sliding, problematic timely repairing, maintenance；
(2) system lining process
A, lining resin are prepared.The resin formula body made by quality testing department according to working environment at that time, temperature conditionss
System carries out lining resin and dissolved, and dosage will rationally be grasped according to manufacture progress.When field condition changes, quality testing department
Should adjust formula in time with manufacturing sector, and by new formula prepare need to resin；
B, reinforcing material prepare.By design requirement by make liner need to reinforcing material be transported to specified location, it is and right
The first processing of cutting of the reinforcing materials of some wide formats is to designing width；
C, inner liner make.Inner liner making is carried out by the laying step of design requirement, should be applied during each individual layer laying
Plus rational tension force, each other appropriate overlap joint, and rolled repeatedly with combined pressure roller and drive bubble out of to ensure complete wet.
And require that each layers of reinforcement reaches the resin content requirement of design；
D, preliminary self-inspection.It has been coated with by design requirement after each layer, it is desirable to which operator carries out preliminary quality testing：Liner
Whether design thickness is reached, it is local whether to have poor glue, kiss-coating phenomenon, if to have hickie, bubble, if having, if occurring above-mentioned
Situation should be reported without delay and take treatment measures；
E, into liner far infrared deeply-curing process.
(3) far infrared deeply-curing
The GRP pipe that our factory is manufactured must all carry out far infrared deeply-curing processing, it is therefore an objective to：It can improve
The curing degree of inner liner, improves the anti-rotten heat resistance of pipeline；
(4) procedure quality is examined
Reaffirm liner bubble-free, stomata before winding, free from admixture, surfacing, resin content rationally, no hickie and
The phenomenon such as local solidification is bad.It must conscientiously check whether liner is qualified, it is underproof to forbid upper machine to wind.
(5) winding working procedure
Designed parameter is inputted into microcomputer, after after liner solidification, carried out by microcomputer control with alkali-free Non-twisting glass fibre
Reciprocating winding is until winding layer thickness.By the external protection of the resin content of specific thickness external application 100%.The resin of winding layer contains
Amount generally 35% or so, its thickness depends on the synthesis of the strength and stiffness of pipe design.
(6) it is infrared ray cured
Pipeline enters the curing conservation stage.With suitable rotating speed mould should be kept to roll in the curing process, make its uniform
Solidification.It should be noted that monitoring pipe temperature, Reasonable adjustment solidification scheme in solidification process.
(7) repair, be stripped：
When the hardness Barcol of pipeline is more than 30, pipe end is repaired.Then with hydraulic ingot stripper by pipeline and
Mould is separated, and is marked on request in its pipeline center section.
Embodiment 1：
A) frp lining layer preparation section：
