Silicon and oxygen generate SiO2After be attached to the product surface time be 5-10min, plate AF liquid medicine, time 5-15min.
Further, once sprayed in the step (3) primer priming paint with a thickness of 35-45 microns, for fill up close
The gap thickness that gold and plastic cement combine.
Further, in the step (5) it is secondary spraying primer priming paint with a thickness of 35-45 micron, for fill up conjunction
The gap thickness that gold and plastic cement combine.
Further, the priming paint of step (7) spraying is acrylate, with a thickness of 15-25 microns, for increasing
Adhesive force.
Further, the colored paint of step (8) spraying is that acrylate adds pigment, with a thickness of 5-15 microns, is used
In abundant product colour.
Further, the finishing coat of the step (9) spraying is polyurethane resin, and with a thickness of 20-30 microns, the finishing coat is
Protective layer, for increasing wear-resisting and scratch resistant performance.
The present invention has the advantages that
1. by the interior injection moulding plastic material of alloy come solve alloy because part processing technology is restricted so that mobile phone shell not
The problem of full alloy can be used；
2. being sprayed by alloy surface, and progress PVD is oxidizable unsightly to solve alloy on the basis of spraying
Defect, enhance the corner volume wear-resisting property of shell and realize beautiful and durable combination；
