Qhov zoo ntawm TPU cov ntaub ntawv yog dab tsi?
TPU txheej txheej txheej txheej thiab cov khoom lag luam yog qhov txuas ntxiv ntawm cov txheej txheem txheej txheem ib zaug.
TPU hu ua Thermoplastic Polyurethane Elastomer, thiab TPU yog nws cov lus Askiv luv. Muab faib ua ob hom: hom polyester thiab hom polyether. Vim yog hom sib txawv, kev ua haujlwm kuj txawv. Cov khoom tseem ceeb ntawm TPU polyester: roj tsis kam, hnav tsis kam, lub zog ua haujlwm zoo, qaug zog tiv taus, tiv taus xeb, zoo elasticity, thiab lwm yam; cov khoom tseem ceeb ntawm polyether TPU: hydrolysis tsis kam, tshuaj tua kab mob, tsis kub hloov pauv, kov tau zoo, Ua tau zoo, thiab lwm yam; nws cov yam ntxwv sib xws yog: zam, zoo ib puag ncig, thiab tuaj yeem hloov PVC (polyvinyl chloride), vim tias PVC decomposes tom qab raug faus rau hauv av rau 3 txog 5 xyoos, thiab nws yuav tsim cov tshuaj chlorine thaum nws decomposed, uas yog tshuaj lom, ua rau hnyav ib puag ncig muaj kuab paug; TPU yuav decomposed tom qab raug faus rau hauv av li 1 xyoos. Tom qab decomposition, nws yuav dhau los ua dej=hydrogen thiab oxygen. Yog li ntawd, qhov zoo tshaj ntawm TPU thiab kev tiv thaiv ib puag ncig kev txiav txim siab nws siv dav.
