One, introductive ABS is a kind of plastic abbreviation, full name is propylene eyeball (one butadiene of A) (one styrene of B) (S) 3 yuan of copolymer, have hardness of avirulent insipidity, surface stability of tall, dimension, heat-resisting, be able to bear or endure chemistry is corroded, shape to wait with machining easily, reason is versed in in machinery the respect such as container of appliance of sports of industry of course of study, electron, light industry, culture and education, toy, musical instrument, food, furniture all has wide application.
ABS plating on plastics, it is to point to the surface in ABS plastic matrix, through specific treatment the method obtains metallic layer. After plating on plastics, maintained already plastic make a weight the characteristic with the light, strong performance that fight corrode, gift again the wearability of its metal and adornment sex. The purify in new technology activation measure, operate simply already, managing manufacturing cost.
2, experimental method
1, matrix plating pre-treatment: One bath of ビ ? one by one thick change - one bath - one ammonia dip - one bath one by one dip is acerbity - one sensitize - one bath
2, plating chemical plating undertakes below agitate in park plating fluid
3, the plating after chemical plating after cleaning, electrified person chamfer undertakes eletroplating
4, plating aftertreatment: Carry Qiu spring Xi a bit?
3, result and discuss
1, each flow mechanism studies plating pre-treatment the purpose of plating pre-treatment is to adopt regular chemical method, the process of a metallic particle that has catalytic active is fashioned in plastic surface.
(1) goes oily recipe: N12 alkyl of; of AOH60g/L;Na3PO430;Na2C0315 Log/L of benzene sulfur acerbity natrium.
ABS plastic surface has a lot of grease contaminant, go the bilge that oily purpose is eliminate matrix surface, make make in chemistry thick in turning juice can faster ground, even ground is infiltrated by water place, ensure thereby thick change even, raise film adhesion. In the meantime, go oily solution can keep clear of not only the bilge of plastic surface, and the constituent structure that still can change plastic face a little, for thick change offer good exterior structure. If go oily ungodliness, thick change a layer inhomogenous, film adhesion is abhorrent, serious when bring about film local fall off; goes when oil solution temperature passes to make an appearance high changeful form, temperature is too low affect rate. The experiment is used alkalescent the fluid that remove oil, temperature is 65-7000, time is 20 bells. Go after oil, especially some blind aperture are deeper make, the likelihood remains lye, easy with thick change fluid happening soda acid to counteract, reduce thick the use result that turns juice and time, because this requires classics sick at heart,dip, bath hind undertakes issueing a working procedure again.
