Ku rwego rw'inganda rw'imashini zikoresha imikandara ibiri ikomeza, imikandara y'icyuma itagira iherezo ihora ihanganye n'ibibazo bitatu by'umuvuduko mwinshi, gukururana cyane, no gukoresha neza cyane. Uburyo bwo gushyira chrome mu cyuma bukora nk' "intwaro y'imikorere" yakozwe ku buryo bwihariye kuri iki gice cy'ingenzi, hakoreshejwe uburyo bugezweho bwo guhindura ubuso kugira ngo hakemurwe ingorane nyinshi ziterwa n'imimerere igoye yo gukora - ikaba umurinzi utagaragara w'imikorere ihamye y'ibikoresho.
Indangagaciro enye z'ingenzi: kuva ku kuramba kugeza ku guhuza ibikorwa
Ubudahangarwa bw'imyambarire n'igihe kirekire cyo kubaho — Byubakiwe kwihanganira ibisabwa bikomeye:
Urukuta rukomeye rwa chrome rukora umurongo w’ubwirinzi ukomeye hamwe n’ubukana bwarwo bukabije. Iyo igitutu gikomeje kugera kuri megapascals nyinshi kandi kigenda cyihuta cyane, kirwanya kwangirika guterwa no gukururana hagati y’umukandara w’icyuma, ibumba, n’ibikoresho. Kigabanya gushwanyagurika kw’ubuso no kwangirika kw’umunaniro, kikongera cyane uruziga rwo gusimbuza umukandara kandi kigakomeza kuramba mu gihe cy’ibikorwa bikomeye.
Kurinda ingese — Kwirinda ibibangamira ibidukikije:
Iyo ishyizwe mu mwuka, urwego rwa chrome rukora firime nini ya Cr₂O₃ irinda gusohoka, ikora nk'ikoti ririnda umukandara w'icyuma. Iyi firime nto cyane itandukanya neza ubuso bw'umukandara n'amazi, ogisijeni, ibisigazwa by'amavuta, icyuma gikonjesha, n'ibindi bintu byangiza. Irinda ingese no kwangirika k'umukandara w'icyuma, kandi ikiruta byose, yirinda gushwanyagurika kw'uduce twa oxide dushobora kwanduza ibikoresho byatunganyijwe - bifasha kubungabunga ibidukikije bisukuye n'ubwiza bw'ibicuruzwa buri gihe.
Kugabanya Ingufu — Kongera Inzira y'Ibikorwa:
Umukandara w'icyuma upfutse chrome ufite ubuso bworoshye nk'indorerwamo bufite ubushobozi buke bwo gufatana. Iyo ukoresheje ibintu bivanze bya resin nka karubone n'ibindi bikoresho byihariye, bigabanya cyane ubushobozi bwo gufatana no gukuraho. Ibi ni ingirakamaro cyane ku mikorere ihoraho, bikarinda kwangirika kw'ibice biva mu gusohora nabi - bigatuma umusaruro ugenda neza kandi neza.
Gukomera k'ubushyuhe — Byakozwe mu bikorwa bikoresha ubushyuhe bwinshi:
Mu gihe cyo gukoresha ingufu zihoraho, ubushyuhe bwinshi bushobora guteza ibibazo mu mikorere. Uru ruhago rutwikiriwe na chrome rugumana imiterere ihamye y’umubiri n’iya shimi ku bushyuhe buri munsi ya 400 °C, bigatuma rushobora guhangana n’ihindagurika ry’ubushyuhe riterwa no gushyuha cyangwa ubushyuhe bwo hanze. Ibi birinda kwangirika k’imikorere bitewe no kwaguka k’ubushyuhe cyangwa ogisijeni, bigatuma habaho imikorere yizewe mu gihe cy’ubushyuhe bukabije.
Uru rukuta rusa n'aho rworoshye rukozwe muri chrome, rufite imiterere yihariye y'umubiri n'iya shimi, rwabaye "ivugurura ry'ibanze" ry'imashini zikomeza gukoresha imikandara ibiri zihura n'imimerere igoye yo gukora. Ntirwongera gusa ubushobozi bw'ibikoresho no gukora neza, ahubwo runatuma ibice biramba - bigabanya cyane ikiguzi cy'imikorere y'igihe kirekire. Mu by'ukuri, ni urugero rwiza rw'ikoranabuhanga ryo gutunganya ubuso mu nganda rikoreshwa mu nganda zigezweho.
Ni ngombwa kuvuga ko MINGKE yashoboye gukora imikandara y'icyuma ikozwe muri chrome, kandi nubwo yashishikarije cyane guhanga udushya mu ikoranabuhanga, yahoraga yibuka inshingano zayo mu mibereho myiza y'ikigo kandi yiyemeje gutanga umusanzu mwiza mu kuvugurura no guteza imbere inganda zikora ibikoresho byo mu rwego rwo hejuru.
