Kana zvasvika pakushandisa electroplating, tinofanira kutanga tanzwisisa kuti chii chaizvo. Muchidimbu, electroplating inzira yekushandisa musimboti we electrolysis kuisa chidimbu chakatetepa chesimbi kana alloys pamusoro pesimbi.
Izvi hazvisi zvekuda chitarisiko, asi chinonyanya kukosha ndechekuti zvinogona kudzivirira oxidation nengura, ukuwo zvichivandudza kuramba kwekupfekwa kwepamusoro, kufambisa mvura, uye kuramba ngura. Ehe, chitarisiko chinogonawo kuvandudzwa.
Kune mhando dzakawanda dze electroplating, dzinosanganisira copper plating, gold plating, silver plating, chrome plating, nickel plating, uye zinc plating. Muindasitiri yekugadzira, zinc plating, nickel plating, uye chrome plating zvinonyanya kushandiswa. Ndeupi musiyano uripo pakati pezvinhu zvitatu izvi? Ngatitarisei chimwe nechimwe.
Zinc plating
Kuputira zinc inzira yekuputira zinc pamusoro pesimbi kana zvimwe zvinhu, kunyanya kudzivirira ngura uye kushongedza.
Hunhu hwayo hwakaderera, inodzivirira ngura zvakanaka, uye ine ruvara rwesirivha chena.
Inoshandiswa zvakanyanya pazvinhu zvinodzivirira mitengo uye zvinodzivirira ngura zvakaita se screws, circuit breakers, uye zvigadzirwa zvemaindasitiri.
Kuputira nickel
Kuisa nickel plating inzira yekuisa rukoko rwenickel pamusoro pechinhu kuburikidza ne electrolysis kana nzira dzemakemikari.
Hunhu hwayo ndehwekuti ine chitarisiko chakanaka, inogona kushandiswa pakushongedza, hunyanzvi hwayo hwakaoma zvishoma, mutengo wayo wakakwirawo, uye ruvara rwayo rwakachena sesirivha uye ruvara rweyero.
Uchazviona pamitsetse yemarambi, mari, nezvimwe zvinhu zvekushandisa zvinochengetedza simba.
Kuputira Chrome
Kuisa chrome pamusoro pechinhu ichi inzira yekuisa chromium pamusoro. Chrome pachayo isimbi chena yakajeka ine ruvara rwebhuruu.
Kuputira Chrome kwakakamurwa kuita mhando mbiri: imwe inoshongedza, ine chitarisiko chakajeka, inodzivirira kupera, uye inodzivirira ngura yakaipisisa zvishoma pane zinc plating asi iri nani pane oxidation yenguva dzose; Imwe inoshanda, nechinangwa chekuwedzera kuomarara uye kuramba kupera kwezvikamu.
Kushongedza kunopenya pamidziyo yemumba nezvinhu zvemagetsi, pamwe chete nezvishandiso nemapombi, zvinowanzoshandisa chrome plating.
Musiyano mukuru pakati pevatatu ava
Kuisa chrome paganda kunonyanya kushandiswa kuwedzera kuomarara, runako, uye kudzivirira ngura. Hunhu hwemakemikari e chromium layer hwakagadzikana uye hahusangani mu alkali, nitric acid, uye akawanda ma organic acids, asi anonzwa hydrochloric acid uye hot sulfuric acid. Haichinje ruvara, ine kugona kudzoreredza kwenguva refu, uye yakasimba kupfuura sirivha ne nickel. Maitiro acho anowanzo kuve e electroplating.
Kuisa nickel plating kunotarisa pakudzivirira kupfeka, kudzivirira ngura, uye kudzivirira ngura, uye chifukidziro chacho chinowanzova chitete. Kune mhando mbiri dzemaitiro: electroplating uye chemistry.
Saka kana bhajeti iri shoma, kusarudza zinc plating ndiyo sarudzo chaiyo; Kana uchitsvaga mashandiro akanaka uye chitarisiko chakanaka, unofanirwa kufunga nezve nickel plating kana chrome plating. Saizvozvowo, hanging plating inowanzo kudhura kupfuura rolling plating kana tichitarisa maitiro.
