Description
Technical field
The present invention relates to a kind of vacuum plating process, is specifically a kind of process for performing vacuum plating on glass.
Background technology
Vacuum plating is to adopt under vacuum condition, by modes such as distillation or sputters, deposits the film coating method of various metals and nonmetal film at glass surface.By such mode, can obtain very thin overlay coating, speed is fast, and sticking power is good, and little to the pollution of environment.
The technical process of General Proper dummy plating is as follows: product surface cleans, goes that static, spray base, priming paint are dry, vacuum plating, topcoating, finish paint are dry, packing.
Because parison surface is smooth not or meeting residual air bubble often, Direct Electroplating can cause rough, glossiness is low, metal sense is poor, and there will be bubble, the undesirable conditions such as bubble. after spraying one deck priming paint, can form a smooth even curface, and the generation of having stopped the bubble bubble of glass existence itself, is represented the effect of electroplating.Spray paint is in order to protect metal-plated rete.
Vacuum plating product coating embrittlement in the past or firm not, often easily comes off, and this is because common technical process exists following defect:
(1) parison surface cleaning is general only soaks 3-5 minute with clear water, and dust and oil stain are removed thorough not, cause the sticking power of coating and glass surface strong not;
(2) when priming paint or finish paint spray, compressed air stream contains impurity, causes coating disturbed by the extraneous factors such as impurity, affects the sticking power of coating and glass surface;
(3) primer coating softness is inadequate, causes the sticking power in primary coat such as aluminium lamination, chromium layer oxide compound in the coating of vacuum plating to weaken, and then the firmness that is coated with of influence surface;
(4) when priming paint and finish paint spray, temperature and streamline linear speed are not done to definite setting, cause paint adhesion unstable;
(5) parameter when priming paint and finish paint are dry arranges unreasonable, causes coating not dry, do not have firm attachment on glass completely, or dries excessively, causes coating embrittlement.
