Iyini i-Phosphate coatings

Imikhiqizo ye-phosphate zisetshenziselwa ukukhulisa ukumelana nokugqwala nokwenza ngcono upende wempuphu ukunamathela, futhi asetshenziswa ezingxenyeni zensimbi ukumelana nokugqwala, ukuthambisa, noma njengesisekelo sokumbozwa okulandelayo noma ukupenda. Isebenza njengengxube yokuguqula lapho kufakwa khona isixazululo se-phosphoric acid nosawoti we-phosphate ngokufafaza noma ukucwiliswa futhi kusabela ngamakhemikhali. nengaphezulu lengxenye elimbozwayo ukuze lenze ungqimba lwe-phosphates engancibiliki, icrystalline.Izingubo zokuguqula i-phosphate zingasetshenziswa naku-aluminium, zinc, cadmium, isiliva kanye nethini.
Izinhlobo eziyinhloko zezingubo ze-phosphate ziyi-manganese, insimbi kanye ne-zinc.I-Manganese phosphates isetshenziselwa kokubili ukumelana nokugqwala kanye nokugcoba futhi isetshenziswa kuphela ngokucwiliswa. Ama-iron phosphates ngokuvamile asetshenziswa njengesisekelo sokumbozwa okwengeziwe noma ukudweba futhi asetshenziswa ngokucwiliswa noma ngokufafaza. Ama-zinc phosphates asetshenziselwa ukuvikela ukugqwala (P&O), isendlalelo sesisekelo se-lubricant, nanjengesisekelo sikapende/sokumboza futhi angasetshenziswa ngokucwiliswa noma ngokufafaza.
I-phosphate coating iyisendlalelo soguquko kokuyisikhombisaral inhlonipho. Ayiminyene kakhulu kunezinsimbi eziningi kodwa iminyene kakhulu kunezingubo zokugqoka. Inezici zokunweba ezishisayo eziphakathi nendawo phakathi kwaleyo yensimbi nokunameka. Umphumela uba ukuthi izingqimba ze-phosphate zingakwazi ukushelela izinguquko ezingazelelwe ekwandiseni okushisayo obekungaba khona phakathi kwensimbi nopende. I-phosphate coatings i-porous futhi ingakwazi ukumunca ukugqoka. Lapho ukwelapha, upende uyaqina, uvale kuma-pores we-phosphate. Ukunamathela kuthuthukiswa kakhulu.

STAGE PHOSPHATE SPRAY PROCESS

1. Ukuhlanza okuhlanganisiwe kanye ne-phosphating. Imizuzu engu-1.0 ukuya ku-1.5 ku-100 degrees F kuya ku-150 degrees F.
2. Hlanza ngamanzi 1/2 iminithi
3. I-Chromic acid hashaza noma ihlanza amanzi enziwe nge-deionized. 1/2 iminithi.
