Wakora iki niba ubuziranenge bw'ibikoresho bigenzura ifuro rya PVC ari bubi?

Mu gihe cyo gusohora ifuro ry'ibikoresho, umwuka uboze n'umushongi w'ifuro urema udupfumu mu gushonga. Hariho icyerekezo cy'udupfumu duto twaguka tujya mu dupfumu tunini muri utwo dupfumu. Ingano n'ingano y'udupfumu ntibifitanye isano gusa n'ingano y'umushongi w'ifuro wongewemo, ahubwo binafitanye isano n'imbaraga z'umushongi wa polymer. Iyo ubukana ari buke cyane, umwuka ushobora gusohoka byoroshye iyo ugeze ku buso bw'umushongi, maze udupfumu duto tugahurira hamwe tugakora udupfumu tunini. Iminyururu miremire ya molekile y'ibikoresho bigenzura ifuro irahambirwa kandi igafatana n'iminyururu ya molekile ya PVC, igakora imiterere runaka y'urusobe. Ku ruhande rumwe, bituma ibikoresho bitera plasticization, kandi ku rundi ruhande, byongera imbaraga za PVC, kugira ngo urukuta rw'uturemangingo twa foam rushobore kwihanganira igitutu cya gaze iri mu turemangingo twa foam mu gihe cyo gusohora ifuro, kugira ngo idacika kubera imbaraga zidahagije. Ibikoresho bigenzura ifuro bishobora gutuma imyenge y'ibicuruzwa iba mito kandi myinshi, hamwe n'imiterere y'imyenge isa kandi ikwiye, bigabanya cyane ubucucike bw'umubiri wa foam. Ubwiza buke cyangwa ingano idahagije y'ibikoresho bigenzura ifuro bishobora gutuma ifuro rigabanuka, bigatera utupfumu duturika cyangwa tw'imigozi.

Uburemere bwa molekile n'uburemere bw'ibikoresho bigenzura ifuro bikorwa n'inganda zitandukanye biratandukanye cyane. Iyo ibikoresho bikwirakwiza ifuro byacitse cyangwa bigateranya uduce duto, n'ubundi buryo budakora neza, gusimbuza ibikoresho bigenzura ifuro cyangwa kongera ingano ikwiye akenshi bishobora kugira ingaruka zikomeye. Ariko, kongeramo cyangwa gusimbuza ibikoresho bigenzura ifuro bifite uburemere bwinshi bwa molekile bishobora kongera ubucucike bw'ibicuruzwa bitewe n'uburemere bukabije, ibyo bikabuza ko uduce duto duto twangirika. Kandi bitewe n'uburemere bwinshi bw'ibice bishonga, uburemere buragabanuka, bigatuma ifuro risohoka nabi, bigira ingaruka ku buso bw'isahani, ndetse no ku gihe gito cyo kuyikora, bigatuma ifuro rinanirwa, cyane cyane iyo hakozwe amasahani afite ubunini buri munsi ya mm 10.
