Ukwelashwa okungaphezulu kwenqubo yokwelashwa yokuthuthukisa ukusebenza komhlaba kwezakhi. Izindlela zokwelashwa komhlaba zezinto ezahlukahlukene zihlukile. Kodwa-ke, inhloso yazo zonke izindlela ukufezekisa ukumelana nokugqwala komkhiqizo, ukuthuthukisa ukumelana kokugqoka komkhiqizo, noma ukuhlobisa.
Ngesikhathi sokucutshungulwa, ukuthutha, ukugcinwa, njll, ingaphezulu lesisebenzi sokusebenza lithintwa ukusabela okuhlukahlukene kwamakhemikhali, okuvame ukukhiqiza ukungcola okunjenge-oxidation, ukugcwala, nokugqwala ebusweni. Uma umsebenzi wokusebenza ngokungcola usetshenziswa ngqo kwizesekeli zemishini, kuzothinta ngqo ukusebenza kwemishini futhi kusheshiswe ukulahleka kwempilo yensizakalo yemishini. Ngakho-ke, i-workpiepe idinga ukuba ngaphezulu kwephethwe noma ibe nongqimba oluhle lokuzivikela ukuze ugweme imiphumela yokusebenzisa umphumela womshini futhi unwebe impilo yayo yenkonzo. Omunye umuzwa obanzi wekwelashwa komhlaba, kubandakanya izindlela zomzimba nezamakhemikhali ezinjenge-ELEI-Ctroplating, Coang, Chlorination Chlorination, njll; Okwesibili ukuqonda umqondo omncane, okungukuthi, i-sandbsting, ukuqhuma kwaqhuma, njll.
Amabhola ensimbi, angasetshenziswa njengezindima ezimbili zokucubungula nokuba pkuvuswe. Amabhola ensimbi asetshenziselwa ikakhulukazi amabhola ensimbi angenasici nasekuthwaleni amabhola ensimbi emkhakheni wesimboni wanamuhla wezimboni. Ingomane amabhola ensimbi engagqwali Izinto ngokwazo zinokumelana okuthile kokugqwala, ikakhulukazi ibhola lezinsimbi ezingama-304 nensimbi engenasici Kodwa-ke, ubuthakathaka bayo ukuthi ubulukhuni buphansi kakhulu. Uma indawo yokusebenza inezidingo ezithile zobulukhuni nokumelana nokugqwala, izinto ezimbili ze-chrome-plated ze 304 Ibhola yensimbi engagqwali/ Insimbi engenasici 316l ingathuthukisa ubunzima bendawo yebhola lensimbi ngezinga elithile. Ubulukhuni beibisanqenqethaamabhola ensimbi is siqine kakhulu kunaleyo yensimbi engenacala, kepha aswela ukumelana nokugqwala. Ngakho-ke, uma kungekho ukugqokwa okuphezulu kakhulu endaweni yokusebenza, ungacabanga ngokufaka i-nickel yensimbi ebusweni bebhola lensimbi noma ibhola lensimbi yekhabhoni. Idlala indima ekuvinjelweni kokugqwala ngaphansi kwezimo ezithile.
