Filimi yo Guhindura Amabara ya TPU ni filime y'ibanze ya TPU ifite amabara menshi kandi atandukanye yo guhindura imodoka yose cyangwa imiterere yayo ikoresheje gupfuka no gupakira. Filimi yo Guhindura Amabara ya TPU ya BOKE ishobora gukumira neza gucika, kurwanya umuhondo, no gusana imikoba. Filimi yo Guhindura Amabara ya TPU ubu ni yo filime nziza ku isoko kandi ifite akazi kamwe na Filimi yo Kurinda Irangi yo gutanga urumuri rw'ibara; hari ubunini bungana, ubushobozi bwo gukumira gucika no gushwanyuka burarushaho kunozwa, imiterere ya filime iruta kure cyane Filime yo Guhindura Amabara ya PVC, hafi kugera ku gipimo cy'amashishwa y'umuhondo, Filimi yo Guhindura Amabara ya TPU ya BOKE ishobora kurinda irangi ry'imodoka n'ihinduka ry'ibara icyarimwe.
Nk'uburyo buzwi bwo guhindura ibara ry'imodoka, iterambere rya firime ihindura ibara ryamaze igihe kirekire, kandi firime ihindura ibara ya PVC iracyari ku isoko rusange. Uko igihe kigenda cyongerwa, ihuhwa n'umuyaga kandi yumishijwe n'izuba, firime ubwayo izagenda igabanya ubuziranenge bwayo buhoro buhoro, hamwe no gushwanyagurika, gushwanyagurika, imirongo y'umuhondo, n'ibindi bibazo. Kugaragara kwa firime ihindura ibara ya TPU bishobora gukemura neza ibibazo bya firime ihindura ibara ya PVC. Iyi niyo mpamvu ba nyir'imodoka bahitamo firime ihindura ibara ya TPU.
Filimi yo guhindura amabara ya TPU ishobora guhindura ibara ry'imodoka n'irangi cyangwa ikimenyetso uko ubyifuza nta kwangiza irangi ry'umwimerere. Ugereranyije n'irangi ryuzuye ry'imodoka, Filimi yo guhindura amabara ya TPU yoroshye kuyishyiraho kandi irinda ubusugire bw'imodoka neza; guhuza amabara birigenga cyane, kandi nta kibazo cy'itandukaniro ry'amabara hagati y'ibice bitandukanye by'ibara rimwe. Filimi yo guhindura amabara ya TPU ya BOKE ishobora gushyirwa ku modoka yose. Yoroshye, irakomeye, irabagirana, irinda ingese, irinda kwangirika, irinda irangi, nta kole isigaye ifite, yoroshye kuyibungabunga, irinda ibidukikije, kandi ifite amabara menshi.
PVC: Mu by'ukuri ni resin
PVC ni impuzandengo ya polyvinyl chloride. Ni polymer ikorwa na polymerization ya vinyl chloride monomer (VCM) hamwe n'ibikoresho nka peroxides na azo compounds, cyangwa munsi y'urumuri n'ubushyuhe, hakurikijwe uburyo polymerization ya free radical. Vinyl chloride homopolymer na vinyl chloride copolymer byose hamwe byitwa vinyl chloride resin.
PVC y'umwimerere ifite ubushobozi bwo kwirinda ubushyuhe, gutuza no gushyuha; Ariko nyuma yo kongeramo formula ijyanye nayo, PVC izagaragaza imikorere itandukanye y'ibicuruzwa. Mu gukoresha filime zihindura amabara, PVC ifite amabara atandukanye cyane, amabara yuzuye, n'ibiciro biri hasi. Imbogamizi zayo zirimo koroha gushonga, gushishwa, gucikagurika, nibindi.
PFT: irinda kwangirika, irinda ubushyuhe bwinshi, kandi ihora ihagaze neza
PET (Polyethylene terephthalate) cyangwa izwi cyane nka polyester resin, nubwo byombi ari resin, PET ifite ibyiza bimwe na bimwe bidakunze kugaragara:
Ifite imiterere myiza ya mekanike, ifite imbaraga zo gukubita inshuro 3-5 z'izindi firime, kandi irwanya guhindagurika neza. Irwanya amavuta, ibinure, aside igabanya ubushyuhe, alkali, n'ibindi byinshi byangiza. Ishobora gukoreshwa igihe kirekire mu bushyuhe bwa 55-60 ℃, ishobora kwihanganira ubushyuhe bwinshi bwa 65 ℃ mu gihe gito, kandi ishobora kwihanganira ubushyuhe buke bwa -70 ℃, kandi nta ngaruka igira ku miterere yayo ya mekanike mu bushyuhe buri hejuru n'ubuke.
Gazi n'umwuka w'amazi bifite ubushobozi buke bwo kwinjira no kurwanya gaze, amazi, amavuta n'impumuro mbi. Bifite ubwiza bwinshi, bishobora kubuza imirasire ya ultraviolet, kandi bifite ubwiza buhebuje. Ntibihumanya, nta mpumuro, bifite isuku n'umutekano, bishobora gukoreshwa mu buryo butaziguye mu gupfunyika ibiryo.
Ku bijyanye n'ikoreshwa rya firime yo guhindura amabara, firime yo guhindura amabara ya PET ifite uburyo bworoshye bwo kwerekana, ingaruka nziza zo kwerekana iyo ifatiwe ku modoka, kandi nta shusho gakondo y'igishishwa cy'umuhondo iyo ifatiwe. Filime yo guhindura amabara ya PET ifite umuyoboro w'umwuka w'ibishyimbo, woroshye kubaka kandi ntuyoroshye kuwukuraho. Muri icyo gihe, irwanya gucika intege, irwanya umunaniro, irwanya gukururana, ndetse n'ubudahangarwa bwayo byose ni byiza cyane.
TPU: Imikorere myiza, kubungabunga agaciro kurushaho
TPU (Thermoplastic polyurethanes), izwi kandi nka thermoplastic polyurethane elastomer rubber, ni ibikoresho bya polymer bikozwe n'uburyo ingingo zikora kandi zigahindura imiterere yazo mu buryo bwa polymeri. TPU ifite imiterere myiza yo gukomera cyane, gukomera cyane, gukomera, no kudasaza, bigatuma iba ibikoresho bikuze kandi bitangiza ibidukikije. Ibyiza ni ibi bikurikira: gukomera neza, kudasaza, kudakonja, kudasiga amavuta, kudasaza amazi, kudasaza, kudahinduka kw'ikirere, nibindi. Muri icyo gihe, ifite imirimo myinshi myiza nko kudasaza amazi menshi, kudahumeka kw'amazi menshi, kudahumeka neza, kudahura n'umuyaga, kudakonja, kurwanya bagiteri, kudafata ibihumyo, kubungabunga ubushyuhe, kudahura n'imirasire y'izuba, no kurekura ingufu.
Mu minsi ya mbere, TPU yakozwe mu myenda y'imodoka itagaragara, ari na yo yari filime nziza cyane yo gukoresha mu gushushanya imodoka. TPU ubu yakoreshejwe mu bijyanye na filime zo guhindura amabara. Kubera ko igoye gusiga irangi, irahenze cyane kandi ifite amabara make. Muri rusange, ifite amabara adasanzwe gusa, nk'umutuku, umukara, imvi, ubururu, n'ibindi. Filimi ihindura amabara ya TPU inagira imikorere yose y'amakoti y'imodoka atagaragara, nko gusana no kurinda irangi ry'imodoka rya mbere.
Imikorere, igiciro, n'igereranya ry'ibikoresho bya firime zihindura amabara zikozwe mu bikoresho bya PVC, PET, na TPU ni ibi bikurikira: Igereranya ry'ubuziranenge: TPU>PET>PVC
Ingano y'ibara: PVC>PET>TPU
Ibiciro: TPU>PET>PVC
Imikorere y'ibicuruzwa: TPU>PET>PVC
Ukurikije igihe cyo gukora, mu bihe bimwe n'ibidukikije bimwe, igihe cyo gukora cya PVC ni hafi imyaka 3, PET ni hafi imyaka 5, naho TPU muri rusange ishobora kuba hafi imyaka 10.
Niba ukurikirana umutekano kandi ukaba wizeye kurinda irangi ry'imodoka mu gihe habaye impanuka, ushobora guhitamo firime ihindura ibara ya TPU, cyangwa ugashyiraho urwego rwa firime ihindura ibara ya PVC, hanyuma ugashyiraho urwego rwa PPF.
