TPU yog dab tsi? -Kev nkag siab tob txog cov thermoplastic polyurethane elastomers
Thermoplastic Polyurethane Elastomer (TPU) yog cov khoom siv polymer nrog cov elasticity siab, ua haujlwm tsis zoo, roj thiab roj, thiab tiv thaiv kev laus. Vim nws qhov kev ua tau zoo tshaj plaws, TPU tau siv dav hauv ntau yam kev lag luam, los ntawm cov ntaub ntawv khau, tiv thaiv cov khoom siv hluav taws xob rau cov khoom siv hauv kev lag luam, TPU muaj ntau yam kev siv.
Cov qauv tsim thiab kev faib tawm ntawm TPU
TPU yog linear block copolymer, muaj ob ntu: qhov nyuaj thiab qhov muag. Cov ntu nyuaj feem ntau yog tsim los ntawm diisocyanate thiab cov saw txuas ntxiv, thaum cov ntu mos yog tsim los ntawm polyether lossis polyester diol. Los ntawm kev kho qhov sib piv ntawm cov ntu tawv thiab muag muag, TPU cov ntaub ntawv nrog qhov sib txawv hardness thiab kev ua tau zoo tuaj yeem tau txais. Yog li ntawd, TPU tuaj yeem muab faib ua peb pawg: polyester TPU, polyether TPU thiab polycarbonate TPU.

Polyester TPU: Nrog cov roj ua haujlwm zoo thiab tshuaj lom neeg, nws feem ntau yog siv los tsim cov kav dej, cov ntsaws ruaj ruaj thiab cov khoom siv tsheb.
Polyether-type TPU: Vim tias nws zoo dua hydrolysis tsis kam thiab kev ua haujlwm kub qis, nws feem ntau siv rau hauv cov khoom siv khau, cov khoom siv kho mob thiab cov xov hlau thiab cables.
Polycarbonate TPU: sib txuas qhov zoo ntawm polyester thiab polyether TPU, nws muaj kev cuam tshuam zoo dua thiab pob tshab, thiab haum rau cov khoom pob tshab nrog cov kev xav tau siab.

TPU cov yam ntxwv thiab daim ntawv thov zoo
TPU sawv tawm los ntawm ntau lwm cov ntaub ntawv nrog nws cov khoom tshwj xeeb. Cov khoom no suav nrog kev ua haujlwm siab, kev ua haujlwm zoo heev, zoo elasticity thiab siab transparency.TPU kuj muaj kev ua haujlwm zoo rau cov roj, cov kuab tshuaj thiab qhov kub thiab txias. Cov txiaj ntsig no ua rau TPU yog cov khoom siv zoo tshaj plaws rau cov khoom lag luam uas xav tau ob qho tib si yooj thiab lub zog.

Abrasion tsis kam thiab elasticity: TPU siab abrasion tsis kam thiab zoo elasticity ua rau nws cov khoom xaiv rau cov khoom xws li khau khau, log tsheb thiab conveyor siv.
Tshuaj lom neeg thiab roj tsis kam: Hauv kev lag luam chemical thiab mechanical industries, TPU yog dav siv nyob rau hauv cov khoom xws li hoses, seals thiab gaskets vim nws cov roj thiab hnyav tsis kam.
Siab pob tshab: Pob tshab TPU yog dav siv hauv kev tiv thaiv cov khoom siv hluav taws xob thiab cov khoom siv kho mob vim nws cov khoom siv kho qhov muag zoo heev.

Cov txheej txheem tsim khoom thiab kev cuam tshuam ib puag ncig ntawm TPU
Cov txheej txheem ntau lawm ntawm TPU feem ntau suav nrog extrusion, txhaj tshuaj molding thiab tshuab moulding txoj kev, uas txiav txim siab daim ntawv thiab kev ua tau zoo ntawm cov khoom kawg. Los ntawm cov txheej txheem extrusion, TPU tuaj yeem ua rau hauv cov yeeb yaj kiab, daim hlau thiab cov raj; los ntawm cov txheej txheem txhaj tshuaj molding, TPU tuaj yeem ua rau hauv cov duab nyuaj ntawm qhov chaw; los ntawm cov txheej txheem tshuab molding, nws tuaj yeem ua rau ntau yam khoom hollow.
Los ntawm ib puag ncig kev pom, TPU yog cov khoom siv thermoplastic rov ua dua tshiab, tsis zoo li cov thermoset elastomers, TPU tseem tuaj yeem yaj thiab rov ua dua tom qab cua sov. Cov yam ntxwv no muab TPU kom zoo dua hauv kev txo cov khib nyiab thiab txo qis carbon emissions. Thaum lub sij hawm tsim khoom thiab siv, yuav tsum tau them nyiaj mloog mus rau nws tej peev xwm ib puag ncig, xws li volatile organic compound (VOC) emissions uas tej zaum yuav generated thaum lub sij hawm ua.
TPU kev lag luam outlook thiab kev loj hlob sib
Nrog rau kev thov loj hlob rau kev ua haujlwm siab, cov ntaub ntawv zoo ib puag ncig, kev ua lag luam pom zoo rau TPU yog qhov dav heev. Tshwj xeeb tshaj yog nyob rau hauv kev lag luam khau, khoom siv hluav taws xob, kev lag luam tsheb thiab cov khoom siv kho mob, daim ntawv thov TPU yuav nthuav dav ntxiv. Nyob rau hauv lub neej yav tom ntej, nrog rau kev txhim kho thiab kev siv ntawm bio-based TPU thiab degradable TPU, ib puag ncig kev ua tau zoo ntawm TPU yuav tsum tau txhim kho ntxiv.
Hauv cov ntsiab lus, TPU yog cov khoom siv polymer nrog ob qho tib si elasticity thiab lub zog, thiab nws cov kev ua haujlwm zoo heev, tshuaj lom neeg thiab kev ua haujlwm ua rau nws hloov tsis tau hauv ntau qhov kev lag luam. Los ntawm kev nkag siab "dab tsi yog TPU ua los ntawm", peb tuaj yeem nkag siab zoo dua lub peev xwm thiab kev taw qhia ntawm cov khoom no hauv kev txhim kho yav tom ntej.
