TPU ikozwe niki? –Mwunvikane byimbitse ya thermoplastique polyurethane elastomers
Thermoplastique Polyurethane Elastomer (TPU) nigikoresho cya polymer gifite ubuhanga bukomeye, kurwanya abrasion, amavuta namavuta, hamwe nuburyo bwo kurwanya gusaza. Bitewe nibikorwa byayo byiza, TPU ikoreshwa cyane mubikorwa bitandukanye, uhereye kubikoresho byinkweto, imanza zirinda ibicuruzwa bya elegitoronike kugeza kubikoresho byinganda, TPU ifite ibyifuzo byinshi.
Imiterere shingiro no gutondekanya TPU
TPU ni umurongo uhagaritse copolymer, igizwe nibice bibiri: igice gikomeye nigice cyoroshye. Igice gikomeye gikunze kuba kigizwe na diisocyanate no kwagura urunigi, mugihe igice cyoroshye kigizwe na polyether cyangwa polyester diol. Muguhindura igipimo cyibice byoroshye kandi byoroshye, ibikoresho bya TPU hamwe nubukomezi butandukanye nibikorwa birashobora kuboneka. Kubwibyo, TPU irashobora kugabanywamo ibyiciro bitatu: polyester TPU, polyether TPU na polyakarubone TPU.

Polyester TPU: Hamwe no kurwanya amavuta meza hamwe no kurwanya imiti, mubisanzwe bikoreshwa mugukora imiyoboro yinganda, kashe hamwe nibice byimodoka.
Ubwoko bwa TPU: Kubera uburyo bwiza bwo kurwanya hydrolysis no gukora ubushyuhe buke, bukoreshwa kenshi mubijyanye nibikoresho byinkweto, ibikoresho byubuvuzi ninsinga ninsinga.
Polyakarubone TPU: ikomatanya ibyiza bya polyester na polyether TPU, ifite ingaruka nziza zo kurwanya no gukorera mu mucyo, kandi irakwiriye kubicuruzwa bibonerana nibisabwa cyane.

Ibiranga TPU nibyiza byo gusaba
TPU igaragara mubindi bikoresho byinshi hamwe nimiterere yihariye. Iyi miterere irimo kurwanya abrasion nyinshi, imbaraga zubukanishi buhebuje, ubworoherane bwiza no gukorera mu mucyo.TPU nayo ifite imbaraga zo kurwanya amavuta, imashanyarazi nubushyuhe buke. Izi nyungu zituma TPU ibikoresho byiza kubicuruzwa bisaba guhinduka nimbaraga.

Kurwanya Abrasion no gukomera: TPU irwanya cyane abrasion hamwe na elastique nziza ituma iba ibikoresho byo guhitamo ibicuruzwa nkibirenge byinkweto, amapine nu mukandara wa convoyeur.
Kurwanya imiti n’amavuta: Mu nganda z’imashini n’ubukanishi, TPU ikoreshwa cyane mu bice nka hose, kashe na gasketi bitewe n’amavuta yayo ndetse no kurwanya ibishishwa.
Gukorera mu mucyo mwinshi: Transparent TPU ikoreshwa cyane murwego rwo kurinda ibicuruzwa bya elegitoroniki nibikoresho byubuvuzi bitewe nuburyo bwiza bwa optique.

Inzira yumusaruro ningaruka kubidukikije bya TPU
Igikorwa cyo kubyaza umusaruro TPU gikubiyemo ahanini gusohora, gutera inshinge hamwe nuburyo bwo guhumeka, bigena imiterere nigikorwa cyibicuruzwa byanyuma. Binyuze mubikorwa byo gukuramo, TPU irashobora gukorwa muma firime, amasahani hamwe nigituba; binyuze muburyo bwo gutera inshinge, TPU irashobora gukorwa muburyo bugoye bwibice; binyuze muburyo bwo guhanagura, birashobora gukorwa mubicuruzwa bitandukanye.
Dufatiye ku bidukikije, TPU ni ibikoresho bisubirwamo bya termoplastique, bitandukanye na elastomers ya thermoset gakondo, TPU irashobora gushonga no gusubirwamo nyuma yo gushyuha. Ibi biranga biha TPU inyungu mukugabanya imyanda no kugabanya ibyuka bihumanya. Mugihe cyo gukora no kuyikoresha, hagomba kwitabwaho ingaruka zishobora guterwa n’ibidukikije, nk’imyuka ihindagurika y’ibinyabuzima (VOC) ishobora kubyara igihe cyo kuyitunganya.
Isoko rya TPU hamwe niterambere ryiterambere
Hamwe nogukenera gukenera ibikoresho byinshi, bitangiza ibidukikije, isoko rya TPU ni ryagutse cyane. Cyane cyane mubijyanye ninkweto, ibicuruzwa bya elegitoronike, inganda zitwara ibinyabiziga nibikoresho byubuvuzi, ikoreshwa rya TPU rizagurwa kurushaho. Mu bihe biri imbere, hamwe n'iterambere no gushyira mu bikorwa bio-ishingiye kuri TPU na TPU yangirika, biteganijwe ko imikorere y’ibidukikije ya TPU izarushaho kunozwa.
Muri make, TPU ni ibikoresho bya polymer hamwe na elastique n'imbaraga, kandi birwanya kurwanya abrasion, kurwanya imiti no kuyitunganya bituma bidasimburwa mubikorwa byinshi. Mugusobanukirwa "TPU ikozwe niki", turashobora gusobanukirwa neza ubushobozi nicyerekezo cyibi bikoresho mumajyambere azaza.
