Isahani idashobora kwihanganira urutoki ni isahani ihuriweho yabonetse nyuma yo kuvura urutoki hejuru yisahani.Ubuso bw'icyuma cyirinda urutoki icyuma kiroroshye kandi kiringaniye, kandi kwihanganira ni bito.Ikoreshwa ryambere rya tekinoroji yo kurwanya urutoki ni igifuniko kirimo chromium ya hexavalent.Mu gihugu ndetse no hanze yarwo, urupapuro rushyizwemo imbaraga muri rusange, hanyuma igifuniko kama (firime irwanya urutoki) kigashyirwa kuri firime ya passivation kugirango ikore isahani irwanya urutoki.
Urupapuro rwihanganira urutoki ni urupapuro rwometseho rwabonetse hakoreshejwe uburyo bwo kuvura urutoki hejuru yurupapuro.Icyapa cyihanganira urutoki nicyuma cyambere cyatsinze icyemezo cyo kurengera ibidukikije.Yiswe "kwihanganira urutoki" kubera ko ubuso bukoraho n'intoki zisukuye udasize igikumwe.Ubuso bwicyuma cyirinda urutoki icyuma kiroroshye, kiringaniye, kandi kwihanganira bito.Ubushakashatsi n’umusaruro w’ibyapa birwanya urutoki byatangiriye mu Buyapani kandi byinjira mu bucuruzi mu ntangiriro ya za 1980.
Kurwanya urutoki byateguwe mbere kugirango byuzuze ibisabwa nabakoresha mubikoresho byo murugo.Mubikorwa byo gutunganya ibikoresho byo murugo, ibice byinshi bikoraho inshuro nyinshi nabakozi bitewe nibikenewe, kandi ibyuya byu icyuya mumaboko yabakozi bitera umwanda hejuru yibice, bigira ingaruka kumiterere.Kubwibyo, ikibaho kirwanya urutoki cyarakozweho ubushakashatsi kandi gitezwa imbere.
Usibye inzira zidasanzwe, tekinoroji yo kurwanya urutoki yakoresheje imiti irimo chromium ya hexavalent muminsi yambere.Hamwe n’amabwiriza agenga ibidukikije arushijeho gukomera, tekinoroji ya chromium ya hexavalent yasimbuwe buhoro buhoro n’ikoranabuhanga rya chromium ridasanzwe hamwe n’ikoranabuhanga ridafite chromium.Ikoranabuhanga ridafite Chromium ntirifite gusa kurwanya ruswa ya tekinoroji irimo chromium, ariko kandi ifite byinshi bihindura ikoranabuhanga ririmo chromium ridafite.Byakoreshejwe cyane mubikoresho byo murugo, ibikoresho bya elegitoroniki nisoko ryubwubatsi.
Dongjie Wire Mesh irashobora kuguha akayunguruzo k'ibikoresho byanyuma bikozwe mu bikoresho byerekana isahani, kandi birashobora no kuguha imipira yanyuma yibikoresho bitandukanye.Inama zawe ziremewe.
Niba ubikeneye, kanda buto hepfo.
