Uma kuqhathaniswa nokupholisha ngemishini kanye nokupholisha nge-electrochemical, ukupholishwa ngamakhemikhali kwethusi akudingi ugesi namathuluzi okulenga.Ngakho-ke, ingakwazi ukupholisha okuqoshiweishidi lethusienesimo esiyinkimbinkimbi, futhi ukusebenza kahle kokukhiqiza kuphezulu.Ubuso obukhanyayo butholakala ngokupholisha kwamakhemikhali, futhi umphumela wokuhlobisa kanye nezindawo ezingaphezulu zethusi ne-alloy yethusi ziyathuthukiswa.Ipholishi yethusi ingasusa ngokushesha nangempumelelo i-oxide, i-burr, ibala endaweni yethusi, ukuze kuqinisekiswe indawo yokupholisha ebushelelezi, futhi inomphumela othile wokulwa ne-oxidation.
Indlela yokupholisha yeshidi lethusi: ukusetshenziswa kwesisombululo sesitoko se-ejenti, ayikwazi ukuletha amanzi oketshezini lokupholisha.Awekho amafutha ngaphezulu ngaphambi kokupholisha.Gcoba zonke izingxenye zethusi oketshezini olucwebezelayo, cwilisa cishe imizuzu emi-2 kuya kwemizuzu emi-4 ngemuva kokususwa, hlambulula ngokushesha ngamanzi.Ungatshali i-workpiece eningi ngesikhathi esisodwa, kufanele kube nebanga elithile phakathi kwe-workpiece kanye ne-workpiece, ungadluli phakathi kwe-workpiece, futhi ukupholisha kufanele kube lula ngezikhathi ezithile ukuze uphendule i-workpiece, inhloso yokupholisha okufanayo.Uma isetshenziselwa isikhathi esithile, uma kutholakala ukuthi ukukhanya kwe-polish yamakhemikhali kunciphisa, kuyadingeka ukwengeza izithasiselo ezisebenza isikhathi eside, amagremu angu-10 ~ 15 amagremu wezithako ezisebenza isikhathi eside ngekhilogremu ye-polish, gxuma ngokulinganayo ngaphambi kokusetshenziswa.Ngemuva kokuthi ishidi lethusi lihlanjululwe futhi limiswe umoya, umsebenzi olandelayo wenqubo ungenziwa, njengokudlula nokushisela.
Ukuqoshwa kwamakhemikhali eshidi lethusi akugcini nje ngokuba nomphumela omuhle kakhulu wokunciphisa, ngesikhathi esifushane kungenza umkhiqizo uthathe ukubukeka okusha, ngemva kokupholisha umkhiqizo akulula ukugqwala kwe-oxidation nezinye izici, kodwa sidinga ukunaka lapho sisebenzisa, umshini wokupholisha wamakhemikhali une-asidi, ugqwala esikhumbeni, uphatha ngobumnene, futhi ugqoke amagilavu enjoloba.Ukulahlwa kwemfucuza kufanele kuhambe kancane ukuze kugwenywe ukuchaphazeka kubantu.Uma uthinta isikhumba, hlambulula ngokushesha ngamanzi.Sebenzisa isixazululo sesitoko, futhi ugweme ukuletha amanzi ekhambi lokupholisha ngesikhathi sokusetshenziswa.Ngaphambi nangemva kokusetshenziswa kufanele kuvalwe, ungachazi elangeni, gcina endaweni epholile enomoya.
