Imikoreshereze nyamukuru yibikoresho bishya bya polyurethane

Muri iki gihe, ibikoresho byo kubika polyurethane bizwi na buri wese nk'ibikoresho byo kubika, cyane cyane bikoreshwa mu kubika inkuta, kubika imiyoboro ahantu h'ingenzi, nk'imiyoboro ya peteroli, imiyoboro ya gaze hamwe n'inkuta z'inzu.

Umuyoboro wibyuma bya polyurethane urwanya ikoreshwa ryicyuma nkigice cyo gukingira hanze, hamwe nimbaraga nyinshi.Ntibyoroshye kwangiza kandi birashobora kwihanganira ibiranga umutwaro munini wo hejuru, kugirango ugere ku buzima burebure, umuyoboro w'ikoti w'icyuma ugomba kuba urwanya ruswa.

Igishushanyo mbonera cyo gushyigikira imiterere irumvikana, guterana amagambo ni bito, imbaraga zifatika zagabanutse, ihame ryisesengura ryibikoresho biroroshye, imiyoboro ihamye, umutekano wateye imbere cyane.

Polyurethane insulasiyo yicyuma umuyoboro wa vacuum ikuraho burundu kubaho kwikirere cyumuyaga wo gutwara ubushyuhe no gukwirakwiza ubushyuhe, bikagabanya cyane gutakaza ubushyuhe.Ugereranije nuburyo bwimiterere yikirere, muburinganire bumwe bushobora kugabanya ubushyuhe bwurukuta rwo hanze 8-13° c.

Igikoresho cya vacuum gikemura burundu ikibazo cyurukuta rwimbere rwicyuma cyo hanze gishobora kwangirika byoroshye numwuka ushushe kandi utose, ibyo bikaba bitezimbere cyane mubuzima bwimikorere yumuyoboro ushyinguwe.Ubuzima bwibicuruzwa bwongerewe imyaka 30.

Umuyoboro wa polyurethaneikoreshwa mu miyoboro itandukanye yo mu nzu no hanze, imiyoboro yo gushyushya hagati, imiyoboro yo hagati ikonjesha ikirere, imiti, imiti n’indi miyoboro y’inganda, umushinga wo kubungabunga imbeho.Incamake umuyoboro wa polyurethane wifata kuva havuka ibikoresho bya sintetike ya polyurethane mumyaka mirongo itatu, byabaye nkibikoresho byiza byogukoresha amashyuza niterambere ryihuse, kubishyira mubikorwa biragutse cyane, byinshi kubera ubwubatsi bworoshye, bubika ingufu zo kurwanya ruswa kandi ikoreshwa mumubare munini wo gushyushya, gukonjesha, amavuta, amavuta nubundi bwoko bwimiyoboro.Ikoreshwa cyane mumiyoboro itandukanye yo gushyushya, gukonjesha, amavuta no kohereza amavuta, nibindi.

Inyungu zubukungu zo gukoresha ibikoresho bishya bya polyurethane

Umuyoboroni ikintu cy'ingenzi kigira ingaruka ku kubungabunga ingufu, iterambere no gushyira mu bikorwa imiyoboro ikingira abantu bigenda byitabwaho n'ibihugu byo ku isi.nyuma y’imyaka ya za 70, ibihugu by’amahanga muri rusange biha agaciro umusaruro n’ikoreshwa ry’imiyoboro ikingira, kandi biharanira kugabanya cyane umubare w’ingufu zikoreshwa, bityo bikagabanya umwanda w’ibidukikije ndetse n’ingaruka za parike.Inganda zo gukumira ibicuruzwa mu mahanga zifite amateka maremare, kandi ibikoresho bishya byo gukumira nabyo biragaragara.Mu myaka ya 1980 ishize, iterambere ry’imiyoboro y’Ubushinwa riratinda cyane, uruganda rukora insulasiyo rushobora kubyara gusa umubare muto w’imiyoboro yashyinguwe mu kuzimu, ariko inganda z’ubushinwa nyuma y’imyaka 30 zashyizweho, cyane cyane nyuma y’imyaka hafi 10 y’iterambere ryihuse, benshi ibicuruzwa biva mubusa kugira, kuva kumurongo umwe kugeza gutandukana, ubuziranenge kuva hasi kugeza hejuru, Porogaramu iragenda iba myinshi.Ibikoresho bya polyurethane kuri ubu ni ibikoresho bikoreshwa cyane mu gukumira mu ruhando mpuzamahanga.Rigid polyurethane ifite ibintu byinshi byiza kandi ikoreshwa cyane muburayi no muri Amerika mubijyanye no kubika ubushyuhe.Hafi ya 49% by'ibikoresho byo gukumira mu Burayi no muri Amerika ndetse no mu bindi bihugu byateye imbere ni ibikoresho bya polyurethane, mu gihe mu Bushinwa iki gipimo kiracyari munsi ya 20%.Kubwibyo, haracyari ibyumba byinshi byo guteza imbere umuyoboro w’ibikoresho bya polyurethane mu Bushinwa.

Noneho, natangije imikoreshereze yingenzi yibikoresho bishya bya polyurethane, byateye imbere cyane mumikorere ya insulasiyo ya insulasiyo, kandi binagabanya cyane gutakaza ubushyuhe bwumuyoboro wogukingira, kandi binoza imikorere yuburusiya.Ifite kandi ibyiza byubwubatsi bworoshye, igiciro gito nibindi byiza byinshi, bihinduka umuyoboro mwinshi ibintu ukunda cyane.Nizera ko nyuma y’ibikoresho bishya bya polyurethane bizakomeza gukoreshwa mu bice bishya, ibikoresho bishya bya polyurethane nabyo bizavumburwa.
