Muri iki gihe inganda zubaka ibikoresho, polyurethane nyinshi irashobora kugaragara ku isoko.Polyurethane ni ibintu byinshi cyane, ariko abantu benshi ntibumva icyo polyurethane aricyo cyangwa icyo ikora.Mu gusubiza iki kibazo, umwanditsi yakusanyije amakuru akurikira kugirango aguhe siyanse ikunzwe.“

Polyurethane ni iki?

Izina ryuzuye rya polyurethane ni polyurethane, nijambo rusange kubintu bya macromolecular birimo gusubiramo urethane mumatsinda nyamukuru.Polyurethane ni itsinda rya urethane mugihugu cyanjye, kandi irashobora kandi kuba irimo ether ester urea biuret urea itsinda rya mbere ryitsinda rya polyurethane.Ikorwa na polyaddition ya organic diisocyanate cyangwa polyisocyanate na dihydroxyl cyangwa polyhydroxyl.Ibikoresho bya polyurethane bifite uburyo bwinshi bwo gukoresha, birashobora gusimbuza reberi, plastike, nylon, nibindi, bikoreshwa mubibuga byindege, amahoteri, ibikoresho byubwubatsi, inganda zimodoka, ibirombe byamakara, uruganda rwa sima, amazu yo murwego rwohejuru, villa, ubusitani, amabuye yamabara ubuhanzi, parike n'ibindi

Uruhare rwa polyurethane:

Polyurethane irashobora gukoreshwa mugukora plastike, reberi, fibre, ifuro rikomeye kandi ryoroshye, ifata hamwe nudusanduku, nibindi. Irashobora gukoreshwa mubice bitandukanye byubuzima bwabantu kandi ifite uburyo bwinshi bwo kuyikoresha.

1. Ifuro ya Polyurethane: igabanijwemo ifuro ya polyurethane ikaze, igice cya polyurethane igice cya kabiri na polyurethane yoroheje.Rigid polyurethane ifuro ikoreshwa cyane cyane mukubaka ibikoresho byo kubika amashyuza, ibikoresho byo kubika amashyuza (kubika ubushyuhe bwumuriro wibikoresho, nibindi), ibikenerwa bya buri munsi (ibitanda, sofa, nibindi padi, firigo, ibyuma bifata ibyuma bikonjesha, nibindi, ibice byabigenewe, hamwe na surfboard , nibindi bikoresho byingenzi.), nuburyo bwo gutwara (ibikoresho nkibisenge nigisenge cyimodoka, indege, nibinyabiziga bya gari ya moshi).

2. Polyurethane elastomer: Polyurethane elastomer ifite ibyiza byo gukomera kwinshi, imbaraga zamarira, kurwanya ingaruka, kurwanya abrasion, kurwanya ikirere, kurwanya hydrolysis, kurwanya amavuta nibindi.Ahanini ikoreshwa mubikoresho byo gutwikira (nko kurinda ama shitingi, gukaraba, amapine, kuzunguruka, ibikoresho, imiyoboro, nibindi), insulator, inkweto, nipine ikomeye.

3. Ibikoresho bitarimo amazi ya polyurethane: Ibikoresho bitarimo amazi ya polyurethane biroroshye cyane gukoresha.Irashobora kuvangwa no gutwikirwa kurubuga kandi igakira hamwe nubushyuhe busanzwe nubushuhe, hamwe nigice kitarimo amazi kitagira kashe, reberi ya reberi nibikorwa byiza birashobora kuboneka.Kandi byoroshye gusana nyuma yo kwangirika.Mubisanzwe bikoreshwa nkibikoresho bya pave, ibikoresho byumurongo wumurima, inzira nyabagendwa, ibikoresho byubutaka bwa parike, idirishya ryubushyuhe bwumuriro, nibindi.

4. Igipfundikizo cya polyurethane: Igipfundikizo cya polyurethane gifatanye cyane, kandi firime yo gutwikira ifite imbaraga zo kurwanya kwambara, kurwanya amazi no kurwanya imiti.Ahanini ikoreshwa mubikoresho byo mu nzu, ibikoresho byo kubaka hamwe na wino yo gucapa inganda.

5. Ibikoresho bifata polyurethane: Imikorere yibicuruzwa byakize irashobora guhinduka muguhindura igipimo cya isocyanate na polyol, kugirango gishobore kugera ku gufatira cyane kuri substrate, kurwanya amazi meza, kurwanya amavuta no kurwanya imiti.Ibikoresho bya polyurethane bikoreshwa cyane mubipakira, kubaka, ibiti, imodoka, gukora inkweto nizindi nganda.

6. Ibikoresho byubuvuzi: Polyurethane ifite biocompatibilité nziza, bityo ikoreshwa buhoro buhoro nkibikoresho byubuvuzi.Irashobora gukoreshwa mugukora pacemakers yumutima yumutima, imiyoboro yamaraso yubukorikori, amagufwa yubukorikori, esofagus artificiel, impyiko zimpimbano, membrane dialyse artificiel, nibindi.

Ibyavuzwe haruguru namakuru amwe n'amwe yerekeye ibintu bya polyurethane n'uruhare rwa polyurethane umwanditsi yagukoreye.Polyurethane iragenda igenda ikomera ku isoko ryibikoresho byubaka kubera guhangana kwayo nibindi biranga.Abakoresha barashobora kugura bakurikije ibyifuzo byabo byo guteza imbere urugo.

Itangazo: Ingingo yavuzwe kuri https://mp.weixin.qq.com/s/c2Jtpr5fwfXHXJTUvOpxCg (ihuza umugereka).Gusa kubijyanye no gutumanaho no kwiga, ntugakore izindi ntego zubucuruzi, ntabwo uhagarariye ibitekerezo nibitekerezo byikigo, niba ukeneye gusubiramo, nyamuneka hamagara umwanditsi wambere, niba hari ihohoterwa, nyamuneka twandikire ako kanya kugirango dusibe gutunganya.
