During plastic part plating process, roughening is very important procedure,good effects of roughening will directly affect the adhesive power,glossy and integrity of plating.during roughening, through oxidization by CrO3, dissolved butadiene build 1~2μm anchor bed on plastic part surface. Butadiene’s oxidization give carboxyl and other polar group to surface of plastic parts, all these work will do good to the adsorption of colloid palladium and plating adhesiveness.
Before roughening, Level extent on surface of plastic part will directly affect the etching effect of roughening liquid. Under the same polishing work, high glossy no-welding line Moulding can make the surface of plastic part more smooth, after roughening, the etching effect is more even, plastic part.
