Ib qho khoom zoozaj duab xis tiv thaiv xim (PPF)vam khom Thermoplastic Polyurethane (TPU) ua nws cov khoom siv tseem ceeb, uas txiav txim siab qhov ua tau ntev ntawm zaj duab xis, kev zoo nkauj, thiab kev ua haujlwm. Tam sim no, TPU feem ntau yog muab faib ua aliphatic thiab aromatic hom, nrog lawv qhov sib txawv tseem ceeb yog "kev tiv thaiv daj." Lub rooj hauv qab no qhia meej txog qhov sib txawv tseem ceeb ntawm ob hom TPU:
| Yam ntxwv | Aliphatic TPU | TPU uas muaj ntxhiab tsw qab |
|---|---|---|
| Cov Qauv Tshuaj | Tsis muaj benzene rings (piv txwv li, raws li HDI), ruaj khov. | Muaj cov qauv benzene ring (piv txwv li, raws li MDI). |
| Cov yam ntxwv tseem ceeb | Kev tiv thaiv daj zoo heev: Kev tiv thaiv ntev rau cov duab UV, nrog rau lub sijhawm lav feem ntau tshaj 10 xyoo. Cov qauv nruj: Cov khoom ntim khoom loj, muab kev tiv thaiv khawb thiab kev sib txhuam zoo dua, nrog rau kev cuam tshuam thiab lub zog tensile siab. | Yooj yim rau kev daj: Cov nplhaib Benzene tuaj yeem oxidize nyob rau hauv UV raug, tej zaum yuav ua rau pom kev daj hauv 3-5 xyoos. Kev ywj pheej zoo, tab sis feem ntau qis dua hauv lub zog thiab kev tiv thaiv khawb piv rau cov hom aliphatic. |
| Txoj Haujlwm Lag Luam | Cov khoom siv tseem ceeb rau PPF qib siab, ua rau tus nqi siab dua. | Cov khoom siv yooj yim rau PPF nruab nrab mus rau qis, pheej yig dua. |
Lwm Cov Kev Faib Tawm TPU thiab PPF Cov Khoom Sib xyaw
Dhau li ntawm cov pawg saum toj no, TPU kuj tseem tuaj yeem faib ua pawg raws li nws cov ntu mos mos ua polyester-based thiab polyether-based hom. Polyester-based TPU muaj lub zog zoo dua, tiv taus kev sib txhuam, thiab tiv taus roj; Polyether-based TPU muab kev tiv thaiv hydrolysis zoo dua thiab kev hloov pauv kub qis. Cov ntaub ntawv PPF niaj hnub no feem ntau siv cov qauv zoo tshaj plaws los sib npaug cov khoom no. PPF tiav yog cov qauv ntau txheej. Dhau li ntawm TPU txheej hauv paus, nws suav nrog:
- Txheej Nplaum: Xyuas kom muaj kev sib txuas zoo thiab tshem tawm cov khoom seem yam tsis ua rau cov xim qub puas tsuaj. Nws xav tau lub zog sib txuas siab thiab tiv taus UV. Cov khoom lag luam zoo kuj tsom mus rau kev tiv thaiv kev hloov pauv ntawm cov yas kom tiv thaiv kev ua tsis tiav ntawm cov nplaum.
- Txheej Sab Saum Toj Uas Muaj Functional: Txheej sab nraud tshaj plaws, txiav txim siab qhov kev paub ntawm tus neeg siv. Cov haujlwm tseem ceeb suav nrog kev kho nws tus kheej (siv cov hydrogen bonds hauv txheej uas kho cov khawb me me nrog cua sov), cov yam ntxwv hydrophobic thiab oleophobic (ua kom yooj yim ntxuav), thiab muab cov teebmeem pom xws li cov xim ci ntsa iab lossis cov xim matte.
Yuav Xaiv Li Cas thiab Cov Qauv Lag Luam
Thaum xaiv PPF, ntxiv rau kev lees paub kev siv aliphatic TPU, koj tuaj yeem xav txog:
- Tshawb xyuas Daim Ntawv Pov Thawj Raug Cai: Cov khoom lag luam TPU aliphatic txhim khu kev qha feem ntau tuaj nrog daim ntawv pov thawj raug cai ntawm 10 xyoo lossis ntau dua, lav qhia meej txog kev ua haujlwm tiv thaiv kev daj.
- Tsom ntsoov rau Kev Siv Tshuab Sab Saum Toj: Lub tsho sab saud muaj feem cuam tshuam ncaj qha rau hydrophobicity, kev kho tus kheej zoo, thiab lub neej ntev. Nug txog cov haujlwm tshwj xeeb ntawm lub tsho.
- Ceev Faj Txog Cov Ntxaib Uas Muaj Tus Nqi Qis: Ceev faj txog cov lus hais txog "aliphatic TPU" ntawm tus nqi qis tshaj plaws, vim tias lawv yuav tsis raug.
Hais txog cov qauv, nrog rau kev thov ntawm cov neeg siv khoom kom zoo thiab ruaj khov, kev ua tau zoo aliphatic TPU, uas sawv cev los ntawm cov ntaub ntawv zoo liLINGHUA TPU series, tab tom dhau los ua qhov kev xaiv tseem ceeb hauv kev ua lag luam.
