Gusohora TPU (Thermoplastic Polyurethane)

1. Gutegura ibikoresho

• TPUGuhitamo ibinure: HitamoUdupira twa TPUhamwe n'ubukana bukwiye (ubukana bw'inkombe, ubusanzwe buri hagati ya 50A na 90D), igipimo cy'umuvuduko w'amazi ashongeshejwe (MFI), n'imiterere y'imikorere (urugero, ubukana bwinshi bwo kwangirika, ubukana, no kudakomera kw'imiti) hakurikijwe ibisabwa ku gicuruzwa cya nyuma.
• Kumisha:TPUIfite hygroscopic, bityo igomba kuba yumye mbere yo kuyisohora kugira ngo ikureho ubushuhe. Ubushuhe bushobora gutera uduheri, inenge zo hejuru, no kugabanuka k'ubushobozi bwa mekanike mu bicuruzwa bisohoka. Kumisha akenshi bikorwa ku bushyuhe buri hagati ya 80 - 100°C mu gihe cy'amasaha 3 - 6.

2. Uburyo bwo Gusohora

• Ibice byo Gusohora Ibintu
  • Umutobe: Umutobe w'umuyoboro ushyushya ahantu henshi kugira ngo ushonge buhoro buhoro uduce twa TPU. Imiterere y'ubushyuhe ishyirwaho neza kugira ngo ishonge neza idashyushye cyane - ibikoreshwa bishobora kwangirika. Urugero, ubushyuhe bw'agace k'ibiryo bushobora kuba hagati ya 160 - 180 °C, agace k'ubushyuhe kakaba hagati ya 180 - 200 °C, n'agace k'ubushyuhe kakaba hagati ya 200 - 220 °C, ariko izi gaciro zishobora gutandukana bitewe n'urwego rwa TPU.
  • Screw: Screw izenguruka mu mugozi, ikajyana, igakanda, kandi igashongaUdupira twa TPU.Imiterere itandukanye ya screw (urugero: single - screw cyangwa twin - screw extruders) ishobora kugira ingaruka ku kuvanga, imikorere myiza yo gushonga, n'umuvuduko w'umusaruro w'inzira yo gusohora. Twin - screw extruders muri rusange zitanga uburyo bwiza bwo kuvanga no gushonga kimwe, cyane cyane ku buryo bugoye.
• Gushonga no Kuvanga: Uko uduce twa TPU tugenda mu mwobo, dushonga buhoro buhoro bitewe n'ubushyuhe buva mu mwobo n'ingufu bivamo no guhindagurika kwa screw. TPU ishongeshejwe iravangwa neza kugira ngo ishonge neza.
• Igishushanyo n'imiterere y'urufaya: Hanyuma TPU ishongeshejwe ishyirwa mu cyuma gishyushye, kigena imiterere y'igice cy'urufaya rwashongeshejwe. Uduce dushobora guhindurwa kugira ngo tubone imiterere itandukanye, nko kuzenguruka imiyoboro, ku ruhande rw'urukiramende ku miterere, cyangwa ku mpapuro n'amafirime. Nyuma yo kunyura mu cyuma gishyushye, TPU ishongeshejwe irakonjeshwa kandi igakomera, akenshi binyuze mu kunyura mu bwogero bw'amazi cyangwa hakoreshejwe uburyo bwo gukonjesha umwuka.

3. Gutunganya nyuma y'ibizamini

• Gupima no Gupima: Kuri bimwe mu bicuruzwa bivanwa mu kirere, ibikorwa byo gupima no gupima ingano birakenewe kugira ngo harebwe neza ingano. Ibi bishobora kuba birimo gukoresha ibikoresho byo gupima, ibigega bipima ingano, cyangwa ibindi bikoresho kugira ngo bigenzure umurambararo w'inyuma, ubunini, cyangwa ibindi bipimo by'ingenzi by'ibicuruzwa.
• Gukata cyangwa Gufunga: Bitewe n'uburyo ikoreshwa, ibicuruzwa bya TPU bivanwamo bicibwa mu burebure bwihariye (ku miyoboro, imiyoboro, nibindi) cyangwa bigashyirwa ku mibumbe (ku mpapuro na firime).
