Abstract
The invention discloses an internal plastic spraying composite galvanized pipe and a production method thereof. The internal plastic spraying composite galvanized pipe is characterized by being composed of a pipe body (1) of the internal plastic spraying composite galvanized pipe, an outer layer galvanized pipe (2) of the internal plastic spraying composite galvanized pipe and an internal plastic spraying layer (3) of the internal plastic spraying composite galvanized pipe. The production method of the internal plastic spraying composite galvanized pipe is characterized in that the spiral motion speed of a high-pressure plastic spray gun is accurately set according to the specification of the inner diameter of the galvanized pipe and the specific character of waste water conveying, and the high-pressure plastic spray gun uniformly sprays hot melting plastic particles to the inner wall of the galvanized pipe in the ring direction while advancing in a spiral mode along the axis of the galvanized pipe. The galvanized pipe has the advantages that the anti-corrosion effect is remarkable, the pressure-bearing and pressure-resisting capacity of a pipeline is improved, and the service life of the pipeline is greatly prolonged.
Description
Technical field
The present invention relates to multiple tube production and processing technical field, be specifically related to a kind of internal plastic spraying Composite Coatings zinc pipe and production method thereof.
Background technique
At present, China's industrial wastewater part is processed in plant area voluntarily, also has quite a few directly to enter city planting ductwork, accept the pipeline overwhelming majority of these waste water conveyings and still continue to use traditional cast iron tube, not only anti-pressure ability is low, and antiseptic property is very poor, and working life is extremely low.Not only, from fact having strengthened entreprise cost, also low environmental wastewater is constituted a threat to.
Summary of the invention
Problem to be solved by this invention is to provide a kind of internal plastic spraying Composite Coatings zinc pipe and production method thereof.It is characterized in that in axial direction spraying equably one deck plastics at galvanized pipe inwall, both played significant anticorrosion ability, increase the pressure-bearing anti-pressure ability of pipeline, and will reach its working life about 50 years, than long 3 times more than of traditional cast iron tube.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: after first galvanized pipe inner wall washing being dried, be fixed on worktable, by high-pressure plastic spray gun along galvanized pipe axis, the formula of spinning is advanced on one side, evenly spray hot melting plastic particle to galvanized pipe inwall hoop on one side, not only fill coarse impurity such as covering galvanized pipe inwall welding bead projection and cadmia, be adsorbed on the plastic layer of galvanized pipe inwall, significantly improved the corrosion resistance on galvanized pipe inwall contact waste water surface.
As a further improvement on the present invention: a kind of internal plastic spraying Composite Coatings zinc pipe and production method thereof, described galvanized pipe, is characterized by Q235 ERW and form through galvanizing.
As a further improvement on the present invention: in described galvanized pipe, spray plastics, it is characterized in that hot melting spraying common PVC plastic pellet, coating thickness according to the general setup control of galvanized pipe specification size between 1.5～2.5 mm.

Embodiment
Contrast accompanying drawing below, by the description to optimum embodiment, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, described a kind of internal plastic spraying Composite Coatings zinc pipe and production method thereof, is characterized in that described internal plastic spraying Composite Coatings zinc pipe forms by spraying plastic layer 3 in internal plastic spraying Composite Coatings zinc pipe body 1, the outer galvanized pipe 2 of internal plastic spraying Composite Coatings zinc pipe, internal plastic spraying Composite Coatings zinc pipe.
As shown in Figure 2, described a kind of internal plastic spraying Composite Coatings zinc pipe and production method thereof, it is characterized in that described internal plastic spraying Composite Coatings zinc pipe production method, by the outer galvanized pipe 1 of internal plastic spraying Composite Coatings zinc pipe, internal plastic spraying Composite Coatings zinc pipe inwall just at hot melting spraying plastic pellet 2, the outer galvanized pipe fixing device 3 of internal plastic spraying Composite Coatings zinc pipe, form along the outer galvanized pipe of the internal plastic spraying Composite Coatings zinc pipe hot melting plastic spray gun 4 moving of axially spinning.
After first outer galvanized pipe 2 inner wall washings being dried, be fixed on worktable 3, according to galvanized pipe internal diameter specification and transport wastewater feature, the concrete high-pressure plastic spray gun 4 spiral motion speed of accurately setting, by high-pressure plastic spray gun 4 along galvanized pipe axis, the formula of spinning is advanced on one side, evenly spray hot melting plastic particle to galvanized pipe inwall hoop on one side, not only fill coarse impurity such as covering galvanized pipe inwall welding bead projection and cadmia, be adsorbed on the plastic layer of galvanized pipe inwall, significantly improved the corrosion resistance on galvanized pipe inwall contact waste water surface.
Complete Deng a galvanized pipe inner-wall spraying, it is unloaded from worktable 3, through port processing, air-dry, check and mark after warehouse-in.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present invention and technological scheme carry out; or without improving, design of the present invention and technological scheme are directly applied to other occasion, all within protection scope of the present invention.
