Nitrile butadiene rubber (NBR) na polyvinyl chloride (PVC) ni ibikoresho bibiri bikoreshwa cyane mu nganda zitunganya ubushyuhe, cyane cyane mu bikoresho by'amashanyarazi n'ubushyuhe. Imiterere yabyo yihariye ituma biberanye n'ibidukikije bitandukanye, ariko imikorere y'ibi bikoresho bitunganya ubushyuhe ishobora gutandukana cyane bitewe n'uburyo bikorwa. Gusobanukirwa ingaruka z'uburyo butandukanye bwo gukora ku mikorere y'ubushyuhe bw'ibikoresho bya NBR/PVC ni ingenzi ku bakora ndetse n'ababikoresha.
Imiterere y’ubushyuhe bw’ibikoresho bya NBR/PVC ahanini iterwa n’uburyo bitwara ubushyuhe, imbaraga za dielectric, no kwihanganira ibintu bidukikije nk’ubushuhe n’ihindagurika ry’ubushyuhe. Iyi miterere igirwaho ingaruka n’uburyo ibikoresho bikoreshwa, inyongeramusaruro, n’uburyo bwihariye bukoreshwa mu gukora.
Imwe mu nzira z'ingenzi zo gukora igira ingaruka ku mikorere y'ubushyuhe ni uburyo bwo guhuza. Muri iki cyiciro, polymer z'ibanze (nitrile rubber na polyvinyl chloride) zivanze n'inyongera zitandukanye, harimo plasticizers, stabilizers, na fillers. Guhitamo inyongeramusaruro n'ubwinshi bwazo bihindura cyane imiterere y'ubushyuhe n'amashanyarazi by'umusaruro wa nyuma. Urugero, kongeramo plasticizers zimwe na zimwe bishobora kunoza ubworoherane no kugabanya imikorere y'ubushyuhe, mu gihe fillers zimwe na zimwe zishobora kunoza imbaraga za mekanike n'ubudahangarwa bw'ubushyuhe.
Indi nzira y'ingenzi yo gukora ni uburyo bwo gusohora cyangwa gushushanya bukoreshwa mu gushushanya ibikoresho bikingira ubushyuhe. Gusohora birimo gukanda uruvange rw'ibikoresho mu gikoresho kugira ngo bikore ishusho ihoraho, mu gihe gushushanya bisaba gusuka ibikoresho mu mwobo wakozwe mbere. Buri buryo butanga itandukaniro mu bucucike, uburinganire, n'imiterere rusange y'ibikoresho bikingira ubushyuhe. Urugero, ibikoresho bikingira ubushyuhe bya NBR/PVC bishobora kugira imiterere ingana neza kandi bikagira imiterere mike ugereranije n'ibicuruzwa bibumba, bityo bikanoza imikorere yabyo yo gukingira ubushyuhe.
Uburyo bwo gukaraba bugira uruhare runini mu miterere y’ubushyuhe bw’ibikoresho bya nitrile rubber/polyvinyl chloride (NBR/PVC). Gukaraba, bizwi kandi nka vulcanization, bivuga inzira yo guhuza iminyururu ya polymer binyuze mu gukoresha ubushyuhe n’umuvuduko, bigatuma ibikoresho bikomera kandi biramba. Igihe n’ubushyuhe by’uburyo bwo gukaraba bigira ingaruka ku miterere ya nyuma y’ibikoresho byo gukaraba. Gukaraba kudahagije bituma ibintu bikomeza gukaraba, bityo bikagabanya ubushobozi bwo guhangana n’ubushyuhe n’imbaraga za dielectric. Kubindi bisobanuro, gukaraba cyane bituma ibikoresho bicika intege kandi bigacika, bityo bigatuma ubushobozi bwabyo bwo gukaraba bugabanuka.
Byongeye kandi, igipimo cyo gukonja nyuma yo gukora bigira ingaruka ku buziranenge n'imiterere y'ibikoresho bya NBR/PVC. Gukonja vuba bishobora gutuma imiterere idahinduka, bishobora kongera ubworoherane ariko bigagabanya ubushyuhe. Ku rundi ruhande, igipimo cyo gukonja buhoro gishobora gutuma kristali ihinduka, bishobora kongera ubushobozi bwo kwirinda ubushyuhe ariko bigatuma ubworoherane bugabanuka.
Muri make, imiterere y’ubushyuhe bw’ibikoresho bya NBR/PVC igirwaho ingaruka zikomeye n’uburyo butandukanye bwo gukora. Kuva ku guhuza no gushushanya kugeza ku gukonjesha no gushyushya, buri ntambwe mu gikorwa cyo gukora ihindura imiterere y’ubushyuhe n’amashanyarazi by’umusaruro wa nyuma. Abakora bagomba gusuzuma neza ibi bintu kugira ngo bongere imikorere y’ubushyuhe bw’ibikoresho bya NBR/PVC ku bikorwa byihariye. Bitewe n’ubwiyongere bw’ubukene bw’ibikoresho bishyuhe by’ubushyuhe bikomeje kwiyongera, ubushakashatsi bukomeje no guteza imbere ikoranabuhanga mu gukora ni ingenzi mu kunoza imikorere y’ibisubizo bya NBR/PVC mu bidukikije bitandukanye.
