Uruhu rwubukorikori rukoreshwa imbere yimodoka harimo cyane cyane PVC (ployvinyl chloride) uruhu rwubukorikori, PU (poly urethane) uruhu rwubukorikori, suede nkuruhu rwubukorikori nubundi bwoko.Nubundi buryo bwuruhu kandi bikoreshwa cyane mubice byimbere nkintebe, imbaho zumuryango hamwe nudupfundikizo twumupira.
1. Kubumba PVC
Ibikoresho by'ibanze by'uruhu rwa PVC ni PVC, naho hepfo ihujwe n'imyenda iboshye cyangwa imyenda iboshye.PVC ifite ibyiza byo gukora byoroshye, ubuziranenge bwibicuruzwa hamwe nigiciro gito ugereranije, ariko uburyo bwo guhumeka ikirere hamwe nubushuhe bwabyo ntabwo ari byiza nkuruhu.Uburyo bwibanze bwo gushiraho nuburyo bukurikira:
Kuvanga: PVC, flame retardant, stabilisateur hamwe nibara bivangwa na pompe vacuum.
Ating Igipfundikizo: hitamo impapuro zisohoka ukurikije imiterere yatoranijwe nigishushanyo mbonera, cyangwa wongere utezimbere impapuro zisohora ukurikije imiterere;Gupfundikanya imvange mu ntambwe ibanza ku mpapuro zisohora, gukama no gutwikira inshuro nyinshi kugirango ugere ku mubyimba ukwiye kandi uburinganire;Hanyuma, umwenda wateguwe uhujwe na PVC isize, hanyuma nyuma yo kongera gukama, impapuro zisohora hamwe nigitambara bizunguruka.
Umurongo wo gukora uruhu rwa PVC rwerekanwe mubishushanyo.
Kubumba
Ibikoresho fatizo byingenzi byuruhu rwa Pu ni polyurethane, ifite ibiranga ubwuzure, kwihangana neza, uburyo bwo guhumeka ikirere hamwe nubushuhe bwamazi, kandi byegereye imiterere yimpu karemano.Urupapuro rwo hejuru Pu artificiel ruhenze ndetse ruhenze kuruta uruhu nyarwo.Uburyo bwo gukora uruhu rusanzwe rwa Pu rusa nubwa PVC.
Ubundi bwoko bwuruhu rwibihimbano bikoreshwa cyane muri iki gihe ni superfine fibre PU, bita superfine fibre PU mugihe gito.Bitandukanye nigitambara cyiboheye cya Pu isanzwe, umusingi wa super fibre PU nigitambara kidoda gikozwe muri fibre yo mu nyanja.Fibre yo mu kirwa ni ubwoko bwa fibre igizwe.Mugice cyacyo cya fibre, imbaraga zinyanyagiye muri substrate nkibirwa, nuko yitwa.Nyuma yimyenda ya super fibre yiboheye muburyo, ikozwe muburyo bwa super fibre base binyuze mu kwibiza hamwe nibindi bikorwa, bifite imiterere irenze PU isanzwe.Uburyo bwo gukora imyenda shingiro yerekeza kumurongo:
PVC umurongo wo gukora uruhu
EUbuboshyi: hitamo fibre ikwiranye na fibre ikwiye, uyikorere ukoresheje inshinge, izunguruka nubundi buryo budoda, hanyuma ubishire muburyo bwumubiri.
MpGutera akabariro: umwenda fatizo uboshye watewe muri resin, gutera inda, gukomera, gukaraba, kandi inzira yavuzwe haruguru irasubirwamo, hanyuma igatunganywa ikazunguruka kugirango ikore umwenda fatizo wa fibre.
Super fibre PU iboneka nyuma ya Pu itwikiriwe hejuru yigitambara cya super fibre.Igikorwa cyo gutwikira hejuru kirasa nubusanzwe Pu na PVC.
