Mu isi y’ubwubatsi n’ubwubatsi ihora ihinduka, gushaka ibikoresho bikomeye kandi biramba ni ingenzi. Mu dushya twagaragaye mu myaka ya vuba aha, imiyoboro ya polyurethane yibanzweho cyane kubera ubushobozi bwayo bwo kunoza kuramba kw’imiyoboro y’imiterere y’ibice bidafite aho bibohera. Iyi nkuru irasuzuma uburyo guhuza imiyoboro ya polyurethane bishobora guhindura ibi bice by’imiterere, bigatuma bikomera kandi bikagira akamaro mu buryo butandukanye.
Imiyoboro y’imyubakire ifite ibice by’ubururu ikoreshwa cyane mu bwubatsi, ibikorwa remezo n’inganda bitewe n’imiterere yayo y’umuyoboro n’ubugari bw’inkuta bumwe. Yagenewe gukwirakwiza imizigo neza kandi ni myiza mu gushyigikira inyubako nk’ibiraro, inyubako n’aho zishyirwa. Ariko, kimwe mu bibazo iyi miyoboro ihura na byo ni uko ishobora kwangirika, kwangirika no kwangirika, cyane cyane mu bidukikije bikomeye. Aha niho imiyoboro ya polyurethane yinjira.
Polyurethane ni polymer ifite ubushobozi bwinshi izwiho imiterere myiza ya mekanike, harimo gukomera cyane, koroherana, no kurwanya imiti n'ibintu bifitanye isano n'ibidukikije. Iyo polyurethane ikoreshejwe nk'urukuta rw'imiyoboro y'imiterere y'ibice bidafite aho bibohera, ikora uruzitiro rurinda umuyoboro rwongera cyane kuramba kwawo. Uru rukuta ntirurinda gusa ingese ziterwa n'ubushuhe n'imiti, ahubwo runagabanya kwangirika kw'ibintu bitera ubushyuhe, bigatuma umuyoboro umara igihe kirekire.
Imwe mu nyungu zikomeye zoumuyoboro upfundikiwe na polyurethaneni ubushobozi bwayo bwo kwihanganira imimerere igoye cyane. Mu nganda nko mu bucukuzi bw'amabuye y'agaciro, peteroli na gaze, no gucunga amazi mabi, imiyoboro ikunze guhura n'ibintu byangiza n'ibikoresho byo kwangiza. Udupira twa polyurethane dukora nk'uruzitiro, tukirinda icyuma kiri munsi yacyo kwangirika no kwemeza ko imiterere y'umuyoboro iguma uko yakabaye. Uku kuramba bivuze ko ikiguzi cyo kubungabunga kigabanuka kandi igihe gito cyo kudakora, bigatuma umuyoboro wa polyurethane uba igisubizo gihendutse ku bucuruzi.
Byongeye kandi, imiterere yoroheje ya polyurethane ituma imiyoboro y’imiterere y’igice cy’ubuso byoroha kuyifata no kuyishyiraho. Ibikoresho gakondo bishobora kuba binini kandi bigoye kuyikoresha, bigatuma ikiguzi cy’abakozi cyiyongera kandi bigatanga gahunda ndende y’imishinga. Mu buryo bunyuranye, imiyoboro y’ubuso ya polyurethane yoroshye kuyitwara no kuyishyiraho, bigatuma inzira yo kubaka irushaho kuba nziza kandi inoza imikorere y’umushinga muri rusange.
Ikindi kintu cyiza ku miyoboro ya polyurethane ni uburyo ikoreshwa mu buryo butandukanye. Ishobora guhindurwa hakurikijwe ibisabwa byihariye, harimo ubugari butandukanye bw'imiyoboro, ubwoko butandukanye bwa polyurethane, n'ingano y'imiyoboro ikozwe mu buryo bwihariye. Uku kwihuza n'uburyo ikoreshwa mu buryo butandukanye, kuva ku bwubatsi bw'amazu kugeza ku mishinga minini y'inganda.
Uretse inyungu zifatika, imiyoboro ikozwe muri polyurethane inagira uruhare mu iterambere rirambye. Mu kongera igihe cyo gukora imiyoboro y’inyubako no kugabanya gukenera gusimburwa kenshi, ubu bushya bufasha kugabanya ikoreshwa ry’imyanda n’umutungo. Byongeye kandi, inzira zo gukora zikoresha ingufu nke zijyanye na polyurethane zifasha kugabanya imiterere ya karuboni, ibi bikaba bihuye n’uburyo bwo gushyira imbaraga mu nyubako zirambye.
Muri make, guhuza imiyoboro ya polyurethane mu miyoboro y’imiterere y’ubuso bw’ubutaka bigaragaza iterambere rikomeye mu ikoranabuhanga ry’ibikoresho. Mu gukomeza kugaragara no kurinda ingese no kwangirika, imiyoboro ya polyurethane irimo guhindura imiterere y’ubwubatsi n’ubwubatsi. Mu gihe inganda zikomeje gushaka ibisubizo binoza imikorere mu gihe zigabanya ikiguzi, gukoresha imiyoboro ya polyurethane bishobora kwiyongera, bigategura inzira y’ibikorwa remezo bihamye kandi binoze.
