Izinzuzo kanye nokubi kwe-Trivalent Chromium Plating

Okokuqala, yini i-Trivalent?

Kuyi-aukuhlobisa kwe-chrome plating, enganikeza ukumelana nokuklwebha nokugqwala ezinketho zemibala ehlukahlukene.I-Chrome encaneibhekwa njengendlela eco-friendly esikhundleni se-chromium ene-hexavalent.

Okulandelayo, Ake sibhekisise le nqubo ukuze siqonde izinzuzo zayo kanye nezinkinga zayo.

Izinzuzo:

Izinzuzo ze-izinqubo ezintathu ze-chromiumphezu kwenqubo ye-chromium ene-hexavalent kukhona ukukhathazeka okumbalwa kwezemvelo ngenxa yobuthi obuphansi be-chromium e-trivalent, ukukhiqiza okuphezulu, nezindleko zokusebenza eziphansi.

Enqubweni ye-chromium engunxantathu, i-chromium ene-hexavalent iwukungcola kokugeza okucwebezelayo.Ngakho-ke, ukugeza akuqukethe inani elincomekayo le-chromium ene-hexavalent.Ingqikithi ye-chromium ye-chromium yezixazululo ze-chromium eyi-trivalent cishe iyingxenye eyodwa kwesihlanu yezixazululo ze-chromium ezine-hexavalent.

Njengomphumela wekhemikhali ye-trivalent chromium electrolyte, ukuxubana akwenzeki phakathi nokucwenga njengoba kwenzeka phakathi ne-hexavalent chromium plating.Ukusetshenziswa kwe-trivalent chromium nakho kunciphisa izinkinga nezindleko zokulahlwa kwemfucuza.

Ububi:

Ububi benqubo ye-chromium engunxantathu ukuthi le nqubo izwela kakhulu ekungcolisweni kunenqubo ye-chromium ene-hexavalent, futhi inqubo ye-chromium e-trivalent ayikwazi ukuhlanganisa uhla olugcwele logqinsi lwepuleti inqubo ye-chromium ene-hexavalent engakwazi ukuyenza.Ngenxa yokuthi izwela ukungcola, inqubo ye-chromium engunxantathu idinga ukuhlanzwa okuphelele nokulawula ilabhorethri okuqinile kunenqubo ye-chromium ene-hexavalent.Amabhavu e-chromium e-trivalent angaba ubukhulu bepuleti obusukela ku-0.13 ukuya ku-25 µm.Ayikwazi ukusetshenziselwa izinhlelo zokusebenza eziningi eziqinile ze-chromium.

Amabhavu ama-trivalent e-chromium electroplating athuthukiswe ngokuyinhloko ukuze athathele indawo yokuhlobisa i-chromium yokucwenga ene-hexavalent.Ukwakhiwa kokugeza okuncanyana kufakazele ukuthi kunzima ngoba i-chromium eyi-trivalent inyibilika emanzini ukuze yakhe ama-ion azinzile angakhululi kalula i-chromium.Njengamanje, kunezinhlobo ezimbili zezinqubo ze-chromium e-trivalent emakethe: iseli elilodwa kanye neseli eliphindwe kabili.Umehluko omkhulu ezinqubweni ezimbili ukuthi isisombululo senqubo yamaseli amabili siqukethe ama-chloride amancane-kuya-kungabibikho, kuyilapho isisombululo senqubo yeseli elilodwa siqukethe ukugcwala okuphezulu kwama-chloride.

Ngaphezu kwalokho, inqubo ye-double cell isebenzisa ama-anode okuhola afakwa emabhokisini e-anode aqukethe isisombululo se-sulfuric acid ehlanjululwe futhi afakwe ulwelwesi olukwazi ukungena, kuyilapho inqubo yeseli elilodwa isebenzisa i-carbon noma i-graphite anode ebekwe lapho kuthintana khona ngqo isisombululo se-plating.Imininingwane ngalezi zinqubo ayitholakali ngenxa yokuthi amabhavu e-chromium ayi-trivalent asemakethe angobunikazi.

Nazi izinzuzo ezinkulu ze-Trivalent chrome:

· Ayinangane nemvelo-intuthu enobuthi embalwa kune-hexavalent plating

· Imfucuza encane

· Izindleko eziphansi zokuhlanza amanzi angcolile

· Imithethonqubo embalwa yokuhlola nezindleko ezihambisanayo

Izithiyo zimi kanje:

· Izindleko eziphakeme kancane zamakhemikhali nokugcinwa kwazo kuqhathaniswa nokucwenga okuyi-hexavalent.

· Ubunzima ekukhetheni i-anode

· Ukwakheka kwesixazululo esiyinkimbinkimbi

· Ubunzima enamathela ukushuba ukwanda
