Description
Technical field
The present invention relates to a kind of vacuum plating process, specifically is a kind of vacuum plating glasswork.
Background technology
Vacuum plating is to adopt under vacuum condition, deposits the film coating method of various metals and nonmetal film at glass surface by modes such as distillation or sputters.Can obtain extremely thin overlay coating by such mode, speed is fast, and sticking power is good, and little to the pollution of environment.
The technical process of general vacuum plating is as follows: product surface cleans, goes static, spray base, priming paint drying, vacuum plating, topcoating, finish paint drying, packing.
Because the parison surface is often smooth inadequately or meeting residual air bubble, Direct Electroplating can cause rough, glossiness is low, the metal sense is poor, and undesirable conditions such as bubble, bubble can appear. spray after one deck priming paint, can form a smooth even curface, and stopped the generation of the bubble bubble of glass existence itself, made that galvanized effect is represented.Spray paint then is in order to protect the metal coatings.
Vacuum plating product coating embrittlement in the past or firm inadequately often comes off easily, and this is because there is following defective in common technical process:
(1) the parison cleaning surfaces is general only soaked 3-5 minute with clear water, and dust and oil stain are removed thorough inadequately, cause the sticking power of coating and glass surface strong inadequately;
(2) priming paint or finish paint when spraying compressed air stream contains impurity, causes coating disturbed by extraneous factor such as impurity, influences the sticking power of coating and glass surface;
(3) the primer coating softness is not enough, causes that sticking power in primary coat such as aluminium lamination, chromium layer oxide compound weakens in the coating of vacuum plating, and then the firmness that is coated with of influence surface;
Temperature and streamline linear speed are not done definite the setting when (4) priming paint and finish paint spray, cause the paint adhesion instability;
Parameter when (5) priming paint and finish paint are dry is provided with unreasonable, causes coating not dry, do not have firm attachment on glass fully, perhaps dries excessively, causes the coating embrittlement.
