Abstract
The invention provides a method for manufacturing a pressure color-change pipe, and is characterized in that a pipe body of the pipe is subjected to cold extrusion with a plant powder and a binder which are evenly stirred, is put into an extruder, and then is subjected to extrusion molding by a 5-20 T hydraulic machine; after the pipe body of the pipe is molded, a metal protective layer, a novel hydraulic layer and an external protective layer are successively sleeved on the outer surfaces of the corresponding layers in a welding mode respectively. The manufacturing method is sample, and color changes of a novel liquid crystal layer can reflect the pressure of a fluid in the pipe, and thus a protective effect is played on the pipe body of the pipe, and the pipe life is improved.
Description
Technical field
The present invention relates to plastic conduit application, especially relate to a kind of preparation method of changing color under pressure tubing.
Background technology
At present, existing tubing great majority are rigidity tubing, easily cause breaking of tubing, thus pollute the fluid in tubing, cause huge economic loss, affect the life of people when the pressure increase of tubing inner fluid.
Summary of the invention
The object of this invention is to provide a kind of preparation method simple, can do tubing fluid pressure in time and detect, thus tubing body is shielded, the changing color under pressure tubing in raising tubing life-span.
Technical scheme of the present invention is: a kind of preparation method of changing color under pressure tubing; it is characterized in that: tubing body puts into extruder after the cold extrusion of plant powder and adhesive uniform stirring; and it is extruded with 5-20T hydraulic press; after described tubing pipe forming, successively the mode that coat of metal, novel hydraulic layer and external protection weld can be enclosed within successively the outer surface of each layer.
The advantage that the present invention has and good effect are: preparation method of the present invention is simple, and the color change of New crystal layer can reflect the pressure of tubing inner fluid, thus shields to tubing body, improves the tubing life-span.
Detailed description of the invention
The invention provides a kind of preparation method of changing color under pressure tubing.A kind of preparation method of changing color under pressure tubing.Tubing body puts into extruder after the cold extrusion of plant powder and adhesive uniform stirring; and it is extruded with 5-20T hydraulic press; after described tubing pipe forming, successively the mode that coat of metal, novel hydraulic layer and external protection weld can be enclosed within successively the outer surface of each layer.
Preparation method of the present invention is simple, and the color change of New crystal layer can reflect the pressure of tubing inner fluid, thus shields to tubing body, improves the tubing life-span.
Above embodiment is to invention has been detailed description, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
Claims (2)
