Thermoplastique polyurethane (TPU) nicyiciro cyihariye cya plastiki cyakozwe mugihe habaye reaction ya polyaddition hagati ya diisocyanate na diol imwe cyangwa nyinshi. Yatunganijwe bwa mbere mu 1937, iyi polymer itandukanye iroroshye kandi irashobora gutunganywa iyo ishyushye, igoye iyo ikonje kandi irashobora gusubirwamo inshuro nyinshi idatakaje ubunyangamugayo. Ikoreshwa haba nka plastiki yubuhanga yoroheje cyangwa nkigisimbuza reberi ikomeye, TPU izwi cyane mubintu byinshi birimo: kuramba cyane nimbaraga zikomeye; ubuhanga bwayo; kandi ku buryo butandukanye, ubushobozi bwayo bwo kurwanya amavuta, amavuta, ibishishwa, imiti na abrasion. Ibiranga bituma TPU ikundwa cyane mumasoko hamwe nibisabwa. Ihinduka ryoroshye, irashobora gukururwa cyangwa guterwa inshinge kubikoresho bisanzwe bikoreshwa mu gukora ibikoresho bya termoplastique kugirango habeho ibice bikomeye mubisanzwe byinkweto zinkweto, insinga ninsinga, hose na tube, firime nimpapuro cyangwa nibindi bicuruzwa byinganda. Irashobora kandi kwongerwaho kugirango ikore ibishushanyo mbonera bya pulasitike cyangwa bitunganyirizwa hakoreshejwe ibishishwa kama kugirango bikore imyenda yanduye, imyenda ikingira cyangwa ibifata neza.
Igitambara kitarimo amazi ya TPU ni iki?
Imyenda idafite amazi ya TPU ni bi - layer membrane ni TPU itunganya ibintu byinshi biranga.
Shyiramo imbaraga nyinshi zo kurira, zidafite amazi, hamwe no kwanduza amazi make. Yateguwe kubikorwa byo kumurika imyenda. Azwiho guhuzagurika, asohora ubuziranenge bwo hejuru, bwizewe cyane bwa termoplastique polyurethane (TPU) hamwe na firime ya copolyester idafite amazi ahumeka munganda. TPU ihindagurika kandi iramba - ishingiye kuri firime nurupapuro bikoreshwa muguhuza imyenda, kutirinda amazi, hamwe nibisabwa byumuyaga cyangwa amazi. Filime nziza cyane na hydrophilique ya TPU hamwe nimpapuro birakwiriye rwose kumurika imyenda. Abashushanya barashobora gukora ikiguzi - uburyo bwiza bwoguhumeka neza buhumeka imyenda muri firime imwe - kugeza - kumurika imyenda. Ibikoresho bitanga guhumeka neza kubakoresha neza. Filime ikingira imyenda hamwe nimpapuro byongeramo gucumita, gukuramo, no kurwanya imiti kumyenda bahujwe.
