Dip itanki pretreatment umgca wemveliso kwiiprofayili
Isishwankathelo
Isixhobo sonyango lwangaphambili siquka idiphu yetanki yangaphambi kokunyangwa komgca wokuvelisa. Umgca wenziwe iinkqubo ezintlanu ezifana etching acid, passivation, ukuhlanjululwa kwamanzi njalo njalo, workpiece ihanjiswa ngebhaskithi yokuxhoma yombane, kunye nolawulo lwezandla, ngaloo ndlela yenza i-workpiece igqibe imfuno yezobuchwepheshe yenkqubo nganye.
Ibhaskithi iyaphakanyiswa kwaye ithotywe etankini ngoncedo lwezandla ukunqanda ukungqubana phakathi kokushukuma kwebhaskithi kunye nodonga lwetanki.
Umboniso weMveliso
Umgangatho weTanki
Utshintsho lwe-welding ye-tank yomzimba kunye nezixhobo ze-peripheral ziyindalo, ngaphandle kokubaleka, ukuvuza, ukuvuza okanye ukuxubha. Umgca womzimba wetanki kunye nodonga lwangaphakathi lwetanki lubanjelwe kakuhle. Uluhlu olupheleleyo lwezixhobo lunengqiqo, kulula ukusebenza kwaye kulula ukugqithisa umgca. Kwangelo xesha, umzimba wonke wetanki wamkela ubume obuphambili, imbonakalo entle ngakumbi.
Izixhobo zomgca wemveliso yonyango kwangaphambili ukuqinisekisa ukuthembeka kwemveliso, izixhobo ezixhasayo kunye nolawulo lwamacandelo: ukukhethwa kwabavelisi abaziwayo bangaphandle ukuqinisekisa umgangatho weprojekthi.
