Filime ya TPU Base ni iki?

Filimi ya TPU ni firime ikozwe mu duce twa TPU binyuze mu buryo bwihariye nko gukaraba, gukata, gusohora firime, no gusiga. Kubera ko firime ya TPU ifite imiterere yo kunyuramo amazi menshi, kunyuramo umwuka, kunyuramo ubukonje, kunyuramo ubushyuhe, kunyuramo kwangirika, kujyanamo umwuka mwinshi, imbaraga nyinshi zo gukurura, no gushyigikira umutwaro mwinshi, ikoreshwa ryayo ni rinini cyane, kandi firime ya TPU iboneka mu bice byose by'ubuzima bwa buri munsi. Urugero, firime za TPU zikoreshwa mu bikoresho byo gupfunyika, amahema ya pulasitiki, uruhago rw'amazi, imyenda ivanze n'imizigo, nibindi. Muri iki gihe, firime za TPU zikoreshwa cyane cyane mu firime zo kurinda irangi mu rwego rw'imodoka.

Mu buryo bw'imiterere, firime yo kurinda irangi ya TPU igizwe ahanini n'ipamba rikora neza, firime y'ibanze ya TPU n'urwego rwo gufatana. Muri byo, firime y'ibanze ya TPU ni yo gice cy'ingenzi cya PPF, kandi ubwiza bwayo ni ingenzi cyane, kandi ibisabwa mu mikorere yayo biri hejuru cyane.

Ese uzi uburyo TPU ikorwamo?

Gukuraho ubushuhe no kumisha: icyuma gikuraho ubushuhe mu buryo bwa molekile, kirengeje amasaha 4, ubushuhe burenze 0.01%

Ubushyuhe bw'imikorere: reba ibyo abakora ibikoresho fatizo basabwa gukora, hakurikijwe ubukana bwabyo, imiterere ya MFI

Kuyungurura: gukurikiza inzira yo gukoresha, kugira ngo hirindwe ko hari utudomo tw'umukara tw'ibintu bidafite aho bihuriye n'amazi

Pompe ishonga: gutuza ingano y'isohoka ry'amazi, kugenzura umuyoboro ufunze ukoresheje icyuma gisohora amazi

Screw: Hitamo imiterere y'icyuma gikata TPU.

Umutwe w'icyuma: shushanya umuyoboro w'amazi ukurikije imiterere y'ibikoresho bya TPU bya aliphatic.

Intambwe yose ni ingenzi cyane ku musaruro wa PPF.

Iyi shusho isobanura muri make inzira yose yo gutunganya polyurethane ya thermoplastic ya aliphatic kuva kuri masterbatch ya granular kugeza kuri filime. Ikubiyemo kuvanga formula y'ibikoresho hamwe na sisitemu yo gukuraho ubushuhe no kumisha, ishyushya, igakata kandi igashyira pulasitiki mu duce duto tw'ibimera bikashonga (bishonga). Nyuma yo kuyungurura no gupima, icyuma cyikora gikoreshwa mu gushushanya, gukonjesha, guhuza PET, no gupima ubunini.

Muri rusange, hakoreshwa ubunini bwa X-ray, kandi hakoreshwa uburyo bw'ibanga bwo kugenzura bufite igisubizo kibi kiva ku mutwe w'icyuma gifata amashusho. Amaherezo, hakorwa uburyo bwo guca impande. Nyuma yo gusuzuma inenge, abagenzuzi b'ubuziranenge bagenzura filime mu mpande zitandukanye kugira ngo barebe niba imiterere yayo yujuje ibisabwa. Amaherezo, imizingo irazingirwa hanyuma igahabwa abakiriya, kandi hagati aho habaho inzira yo gukura.

Ikoranabuhanga ryo gutunganya

TPU masterbatch: TPU masterbatch nyuma y'ubushyuhe bwinshi

imashini ikora ibikoresho byo guterera;

Filime ya TPU;

Gufata imashini ikora: TPU ishyirwa ku mashini ikora thermosetting/light-setting hanyuma igashyirwa ku rundi ruhande rwa acrylic kole/light-curing glue;

Gusiga amavuta: Gusiga amavuta asohora PET hakoreshejwe TPU ifatanye;

Gupfuka (urwego rukora): gupfuka nano-hydrophobic kuri TPU nyuma yo gupfuka;

Kumisha: gukamisha kole iri ku ifiriti hakoreshejwe uburyo bwo kumisha bujyanye n'imashini ikoresha irangi; ubu buryo buzatanga umwuka muto w'imyanda ikomoka ku bimera;

Gukata: Dukurikije ibisabwa mu gutumiza, icyuma gikatamo ibice kizakatamo ingano zitandukanye n'imashini ikatamo ibice; ubu buryo buzatanga impande n'imfuruka;

Kuzunguruka: agapira ko guhindura ibara nyuma yo gukata karahambirwa mu bicuruzwa;

Gupfunyika ibicuruzwa byarangiye: gupfunyika ibicuruzwa mu bubiko.
