Ngaba uyawazi umahluko phakathi kwe-blackening kunye ne-phosphating emnyama yezikhonkwane ezomileyo?

I-Phosphating yinkqubo yokwenza ifilimu yokuguqula imichiza ye-phosphate ngokusebenzisa iikhemikhali kunye neempendulo ze-electrochemical, kunye nefilimu yokuguqula i-phosphate ebizwa ngokuba yifilimu ye-phosphating. Injongo ephambili ye-phosphating kukukhusela isiseko sesinyithi kunye nokukhusela isinyithi ukuba singabikho kumlinganiselo othile; Isetyenziselwa i-priming ngaphambi kokupeyinta ukuphucula ukunamathela kunye nokuchasana kwe-corrosion yefilimu yepeyinti; Isetyenziselwa ukunciphisa i-oyile yokuthambisa ifilimu ngexesha lenkqubo yokusebenza kwesinyithi.

I-Phosphating yindlela eqhelekileyo esetyenziswayo yonyango lwangaphambili. Ngokomgaqo, kufuneka ibe yeyonyango lwe-membrane yokuguqulwa kweekhemikhali. Ngethuba nje isetyenziswe kwi-phosphating yemigangatho yentsimbi, isinyithi esingenawo i-ferrous njenge-aluminium kunye ne-zinc nayo ingasetyenziswa kwi-phosphating. Inkqubo yokuntywilisela i-workpiece (intsimbi, i-aluminiyam, okanye i-zinc) kwisisombululo se-phosphating (ezinye izisombululo ezisekelwe kwi-acidic phosphate) kunye nokubeka ifilimu yokuguqula i-crystalline phosphate enganyibilikiyo kumphezulu ibizwa ngokuba yi-phosphating.

I-Blackening yindlela eqhelekileyo yonyango lobushushu besinyithi. Umgaqo kukudala ifilimu ye-oxide kwi-metal surface ukuze uhlukanise umoya kwaye ufezekise injongo yokuthintela ukugqwala. Xa iimfuno zokubonakala zingekho phezulu, unyango olumnyama lunokusetyenziswa. Umphezulu weendawo zentsimbi ujika ube mnyama, ezinye zazo zibizwa ngokuba luhlaza okwesibhakabhaka. Unyango lwe-Bluing lunyango lomphezulu lwekhemikhali. Umsebenzi wayo oyintloko kukwenza ifilimu ye-oxide exineneyo phezu kwendawo yokusebenza, ukuthintela ukubola kunye nokugqwala, kunye nokuphucula ukunyanzeliswa kokugqoka kwe-workpiece. Kuphela unyango olungaphezulu aluyi kuchaphazela isakhiwo sangaphakathi. Ayilonyango lobushushu, luhluke kakhulu ekucimeni.

Iibholiti zamandla aphezulu zisebenzisa i-phosphating, enokuthi ithintele imiba ye-hydrogen embrittlement. Ke ngoko, iibholithi ezingaphezulu kwebanga le-10.9 kwindawo yoshishino zihlala zisebenzisa unyango lomphezulu we-phosphating. Ukwenza i-Blackening+oiling yingubo ethandwayo yeziqhoboshi zemizi-mveliso kuba yeyona inexabiso eliphantsi kwaye ibonakala ilungile phambi kokuba kusetyenziswe amafutha. Ngenxa yokuba mnyama, phantse akukho mandla okuthintela umhlwa, ngoko iya kugqwala ngokukhawuleza ngaphandle kweoli.

Ukufumana ulwazi oluthe kratya malunga nezikhonkwane ze-drywall, nceda uqhagamshelane nathi.
