Umgca we-Phosphating pretreatment weendawo zetsimbi okanye iindawo ezidibeneyo

I-COATING YETHU inikezela ngemigca yezixhobo ze-phosphating zamva nje zeendawo zetsimbi okanye ii-weldments ezisetyenziswa kwizicelo ezahlukeneyo.

Ingaba ufuna ukuhlaziya imigca emidala, okanye ufuna ukuthenga entsha, nokuba udibane nazo naziphi na iingxaki zobugcisa, vele uqhagamshelane nathi, siya kukubonelela ngesisombululo esisodwa.

Iintlobo zeMizila yePhosphate

● I-iron phosphate

I-iron phosphate yeyona nto ixhaphakileyo yonyango lokwalekwa komgubo ngenxa yokuba inokusetyenziswa phantse ngayo nayiphi na imathiriyeli kwaye ineemveliso zebi-enobuhlobo nokusingqongileyo okanye udaka. Le nkqubo isetyenziswa ngokuqhelekileyo kwizinto zetsimbi.

● I-Zinc Phosphate

I-Zinc phosphate yi-non-metallic, i-crystalline i-coating ebambelele kakhulu kwizinto eziphathekayo. Kubalulekile ukuqaphela, i-zinc phosphate iphuma kwisisombululo ngokwayo, kungekhona ukusuka kwindawo efana ne-iron phosphate coating. Iikristale ze-zinc phosphate ziqala ukubumbeka kwindawo ye-anodic kumphezulu wenxalenye kwaye ziyeke ukubunjwa xa inxalenye yendawo yomhlaba isetyenzisiwe, okt. babetha enye ikristale. Ngokungafaniyo ne-iron phosphate, i-zinc phosphate ayikwazi ukucoca kunye nokugqoka ngexesha elifanayo: ngoko ke, isiteji sesine-ukuhlamba, ukuhlanjululwa, i-zinc phosphate, ukuhlanjululwa kukuseta okuqhelekileyo. Ngelixa i-zinc phosphating ibonelela ngeempawu zokunamathela eziphuculweyo, ukugquma ngcono kwiindawo eziqinileyo kunye nokuchasana nokugqwala okungcono, inkqubo ineendleko eziphezulu zokusebenza, isebenzisa isinyithi esinzima, kwaye inokuvelisa i-sludge eninzi, akukho nanye ehambelana nokusingqongileyo ngenjongo yokulahla. I-zinc phosphate isetyenziswa ngokuqhelekileyo kwizinto zentsimbi.

● Iphosphate yeChromium

I-Chromium phosphate isetyenziswa kakhulu kumalungu asekelwe kwialluminiyam. Ngelixa le nkqubo isebenzayo, njenge-zinc phosphate, isebenzisa iintsimbi ezinzima ezifuna ukufunyanwa ukuze zilahlwe ngokusingqongileyo.

●Ulawulo lweNkqubo yePhosphate

Ukulawula inkqubo ye-phosphating ibalulekile ekufezekiseni iingubo ezihambelanayo ezikhokelela ekugqibeleni kwinkqubo yokugcoba ezinzileyo. Olona lawulo lwenkqubo lubaluleke kakhulu ekuguqulweni kwefosfati zezi:

Ixesha - ixesha elide lokuqhagamshelana ixesha elide lokusabela kweekhemikhali, inkqubo kufuneka ibe yinde ngokwaneleyo ukuvumela i-chemistry ukuba yenze i-coating efanayo.

Ubushushu - iikhemistri zidla ngokuba ndlongondlongo kumaqondo obushushu aphezulu

Ukugxininiswa kunye ne-pH - ngakumbi i-asidi ekugxininiseni ikhawuleza inkqubo yokugquma kwaye inokubangela ubunzima obupheleleyo bokugquma.
