Nkuko bisanzwe, impuzu zifite imirimo ibiri yibanze: gushushanya no kurinda bifite akamaro kanini mubukungu. Ipitingi ikora irashobora gukoreshwa kugirango ihindure imiterere yubuso bwa substrate, nko gufatira, guhindagurika, kurwanya ruswa, cyangwa kwihanganira kwambara. Mu nganda zibyuma, gusiga irangi cyangwa ifu yifu cyane cyane birinda umuyoboro wicyuma gusudira kwangirika, ndetse no gukomeza kugaragara neza.
Irangi na lacquers ni ubwoko bubiri bwingenzi bwibintu bikoreshwa mugukoresha. Mubuhanga, irangi nibikoresho bikoreshwa cyane mukurinda ibyuma murusyo. Sisitemu yo gusiga ibyuma byubatswe byateye imbere mumyaka myinshi kugirango yubahirize amategeko y’ibidukikije mu nganda kandi hasubijwe ibyifuzo by’ikiraro n’inyubako kugirango imikorere irusheho kugenda neza. Buri gipfukisho 'layer' muri sisitemu iyo ari yo yose yo kurinda gifite umurimo wihariye, kandi ubwoko butandukanye bukoreshwa muburyo bwihariye bwa primer bukurikirwa no hagati / kubaka amakoti mu iduka, hanyuma amaherezo cyangwa ikoti ryo hejuru haba mu iduka cyangwa kurubuga . Ifu yifu nayo ikoreshwa cyane mubyuma bikonje bikonje hamwe nifu yumye yumye kugeza mugice cyicyuma kugirango irinde hejuru. Mubisanzwe usiga irangi ritose igipfundikizo gihagarikwa mumashanyarazi atembera mu kirere hasigara igifuniko kirinda ubuso. Igice cyometseho ifu gisukurwa hanyuma ifu yifu ikarishye amashanyarazi hanyuma igaterwa kubintu bigomba gutwikirwa. Ikintu noneho gishyirwa mu ziko aho ifu yuzuye ifu ishonga kugirango ikore firime ikomeza.
Hatabayeho gutwikira, ibyuma cyangwa ibyuma biroroshye kubyara ingese - inzira izwi nka ruswa. Kugirango wirinde ibi, abakora imiyoboro yicyuma bateranya imiyoboro yicyuma bayitwikiriye hamwe na zinc. Bashobora kwibiza imiyoboro mu cyombo cy'icyuma gishongeshejwe cyangwa bagakoresha uburyo bwa electroplating. Mbere yo kohereza imiyoboro, abayikora bakunze gutwikira amavuta ya galvanis hamwe namavuta kugirango bagabanye reaction ya zinc nikirere. Iyo aya mavuta asize, reaction ya zinc hamwe na ogisijeni itanga firime nziza yera ihindura ibara ryicyuma kiva kumururu kikaba cyiza cyane cyera-cyera. Iyo bishyushye bishyushye umuyoboro wibyuma ikeneye gutumizwa mu mahanga, ubu bwoko bwumuyoboro busanzwe bufite firime passivator irinda ibyuma kwangirika mubidukikije byamazi yumunyu mugihe icyuma kinyura mumyanyanja cyangwa inyanja kumato yimizigo.
Muri iki gihe, hari intambwe imaze guterwa mu bikorwa byo gukoresha ikoranabuhanga ryo gutwikira kugira ngo ririnde ruswa ku nyubako zo hanze, ibigega by'imbere mu mavuta y’ibikomoka kuri peteroli, ubwato bw’ubwato, imiyoboro y'amazi, n'ibindi. Hashyizweho uburyo bushya bwo gusana no kurinda beto n'ibyuma. inyubako mumazi yinyanja ninyanja, nkubuhanga bwa polymer enapsulation tekinike yo gusana no kurinda ibyubatswe muri zone ya flash. Ibisabwa birebire byubaka cyangwa ubukanishi kubisabwa runaka birashobora kwizezwa binyuze mukurinda ruswa, binyuze mubitambaro cyangwa guhuza kurinda catodiki no gutwikira.
