Taw qhia ntawm TPU Film

TPU (Thermoplastic polyurethanes), thermoplastic TPU elastomer, yog ua los ntawm MDI uas muaj NCO functional group thiab POLYOL thiab 1.4BG uas muaj OH functional pawg los ntawm extrusion thiab sib tov. Vim nws zoo elasticity, zoo lub cev muaj zog thiab zoo mechanical zog, nws yog dav siv nyob rau hauv kev txhaj tshuaj, extrusion, calendering thiab dissolution rau hauv cov tshuaj resin thiab lwm yam txheej txheem, thiab yog cov khoom siv yas feem ntau siv los ntawm kev lag luam yas, Nws cov khoom npog cov khoom siv. ntau yam ntawm cov ntawv thov kev lag luam thiab kev tsim nyog rau pej xeem.
Nyob rau hauv xyoo tas los no, vim muaj kev txhim kho txuas ntxiv ntawm cov khoom tshiab, kev noj cov thermoplastic PU elastomers tau nce ntxiv, tsim cov hauv kev tshiab rau kev lag luam yas nrog tus nqi qis thiab tus nqi ntxiv.
TPU (thermoplastic polyurethane) yog nce nrov vim nws cov kev ua tau zoo tshaj thiab kev tiv thaiv ib puag ncig. Qhov twg siv PVC, TPU tuaj yeem hloov pauv rau PVC. Txawm li cas los xij, qhov zoo ntawm TPU yog dhau ntawm PVC. TPU tsis tsuas yog muaj cov yam ntxwv zoo ntawm kev kub ceev, siab nro, toughness thiab aging kuj, tab sis kuj yog ib tug paub tab ib puag ncig tiv thaiv khoom. TPU tau siv dav hauv cov ntaub ntawv khau, npaj-rau-hnav, cov khoom ua si ua pa, dej thiab cov khoom ua si hauv qab dej, cov khoom siv kho mob, cov khoom siv dag zog, cov khoom siv hauv tsheb, kaus mom, hnab, hnab tawv, thiab lwm yam.
TPU zaj duab xis yog tsim los ntawm TPU granular cov ntaub ntawv los ntawm calendering, daim kab xev casting, zaj duab xis tshuab, txheej thiab lwm yam txheej txheem. Nws yog dav siv hauv kev ua kis las khau: kev lag luam kho kom zoo nkauj, lub hnab huab cua, lub cushion, roj hnab, thiab lwm yam ntawm ib leeg thiab sab saud. Tam sim no, muaj ob txoj hauv kev hauv daim ntawv thov TPU zaj duab xis hauv cov khau kis las: ib qho yog cov qauv nrov los ntawm cov poj niam khau khiab, uas yog, pob tshab TPU zaj duab xis yog ncaj qha txiav, lossis tshuaj ntsuam luam tawm thiab xim, lossis daim ntaub nplaum yog raws li cov ntaub ntawv sandwich, thiab lwm yam, uas yog tsim thiab sib koom ua ke ntawm lub siab nrog lub siab zaus, nrog rau kev ua haujlwm zoo thiab zoo nkauj. Qhov thib ob yog siv cov dej tsis zoo thiab cov dej noo permeable TPU zaj duab xis thiab cov ntaub ntawv khau kom ua tiav cov dej tsis zoo thiab cov dej noo permeable.
