01: Ibikoresho nibikoresho biranga

Uruhu rwa PU rukoreshwa mu gusimbuza uruhu rwa PVC, kandi igiciro cyarwo kirenze uruhu rwa PVC.Kubijyanye nimiterere yimiti, yegereye umwenda wimpu.Ntabwo ikeneye plasitike kugirango igere kubintu byoroshye, ntabwo rero bizakomera kandi byoroshye.Muri icyo gihe, ifite ibyiza byamabara akungahaye nuburyo butandukanye, kandi igiciro ubusanzwe gihendutse kuruta imyenda yimpu, bityo kikaba cyakirwa nabaguzi.

Ibindi ni uruhu rwa PU.Mubisanzwe, uruhande rwinyuma rwuruhu rwa PU nigice cya kabiri cyuruhu mbisi, rushyizweho urwego rwa PU resin, bityo nanone rwitwa uruhu rwinka rwa firime.Igiciro cyacyo kirahendutse kandi igipimo cyacyo ni kinini.Hamwe nimihindagurikire yikoranabuhanga, ikorwa kandi muburyo butandukanye bwibyiciro bitandukanye, nkimpu zibisi zitumizwa mu mahanga.Kubera ikoranabuhanga ryihariye, ubuziranenge buhamye, ubwoko bushya nibindi biranga, ni uruhu rwohejuru rwohejuru, kandi igiciro cyarwo hamwe n amanota ntabwo biri munsi yimpu yambere.Uruhu rwa PU nimpu nyazo bifite umwihariko wabyo.Kugaragara kwuruhu rwa PU nibyiza kandi byoroshye kubyitaho.Igiciro ni gito, ariko ntabwo irwanya kwambara kandi byoroshye kumeneka;Uruhu nyarwo ruhenze, rutoroshye kubyitaho, ariko biramba.
