Its production process heating the metal member with metal coating to 250-320 deg.c, and spraying plastic to the surface of the metal coating in the speed of 0.5-1 m/min. The present invention has the advantages of simple structure, less production steps and low production cost, and the double layer anticorrosive plastic-steel member may be used widely in pipeline and tanks for water draining, chemical industry, oil and gas conveying, etc.
Description
Technical field
The present invention relates to a kind of anticorrosive plastic-steel metal member and manufacture method thereof, be specifically related to a kind of double layer anticorrosive plastic-steel metal member and manufacture method thereof.
Background technology
In order to prolong the service life of perishable hardware, need commute corroding metal component surface to carry out preservative treatment.In order to reach antiseptic effect preferably, the metal tube in the commute corroding metal member mainly adopts plating layer of metal coating on the surface of metal tube at present, and coating adhesive and plastic layer are bonding on the surface of the coat of metal then.The anticorrosive plastic-steel metal tube that adopts said method to make, in use exist the plastic layer and the coat of metal bonding insecure, plastic layer comes off easily, thereby reduce the antiseptic property of metal tube, simultaneously owing to increased both adhesive layers, so not only increased manufacturing procedure, also increased production cost, adopting bonding method that plastic layer and the coat of metal are linked together has also increased technology difficulty.On the present steel pipes with straight that also only is applied in the perishable hardware of this structure, its range of application is narrower in addition.
Summary of the invention
The objective of the invention is for solving the pipe fitting in the existing perishable hardware owing to adopt bonding method that the coat of metal and plastic layer are linked together, thus exist plastic layer bonding insecure, easily come off, reduced the antiseptic property of metal tube; Because this structure only is applied on the steel pipes with straight, thereby there is the narrow problem of range of application and a kind of double layer anticorrosive plastic-steel metal member and the manufacture method thereof that provide again.It comprises the hardware with coat of metal 1; The surface of the described coat of metal 1 has sprayed plastic layer 3; Described hardware is carbon steel member and/or iron member; Manufacture method of the present invention is: be coated with the coat of metal 1 on the surface of corrosion-prone hardware; When described hardware with coat of metal 1 is heated to 250～320 ℃ plastic-blasting is carried out on the surface of the coat of metal 1 and handle, plastic-blasting speed is 0.5～1m/min; Described hardware is metal pipe material 2-1 or sheet metal 2-2.
The present invention has following beneficial effect: one, the present invention is that metal coating surface on hardware sprays plastic layer, the plastic layer and the coat of metal are combined securely, adopt this connected mode, can guarantee that the plastic layer and the coat of metal forever combine, guarantee that plastic layer does not come off, thereby improved the antiseptic property of perishable hardware greatly.Two, the present invention is owing to adopt the method for plastic-blasting that plastic layer is securely fixed on the surface of the coat of metal, and it is simple in structure, and processing ease has also reduced manufacturing procedure, has reduced production cost.Three, this manufacture method is not only applicable on the corrosion-prone metal tube, also applicable on the corrosion-prone sheet metal, the non-corrosive metal (NCM) member of being made by this manufacture method promptly can be used on the pipelines such as plumbing, chemical industry, oil gas conveying, can be used on again on the various basins of processing and manufacturing.
