TPU muaj lub zog tensile zoo heev, lub zog tensile siab, toughness thiab anti-aging zog, thiab yog ib qho khoom siv tiv thaiv ib puag ncig. Uas yog hais tias, TPU lub tsho tiv nag yog ib hom tsho tiv nag uas pej xeem nyiam niaj hnub no. Kev tiv thaiv txias zoo heev: TPU muaj qhov kub hloov iav qis, tswj tau qhov elasticity zoo, yooj ywm thiab lwm yam khoom siv lub cev ntawm -35 degrees Celsius.
Kev Taw Qhia
TPU yog ib lub npe luv ntawm Thermoplastic Urethane, uas hu ua thermoplastic polyurethane elastomer hauv Suav. TPU yog cov khoom siv polymer ua los ntawm diisocyanate molecules xws li diphenylmethane diisocyanate (MDI) lossis toluene diisocyanate (TDI) thiab polyol loj-molecule thiab polyol qis-molecule (chain extender), uas tau polymerized ua ke hauv kev sib xyaw.
TPU muaj lub zog tensile zoo heev, lub zog tensile siab, toughness thiab kev laus tsis kam, thiab yog cov khoom siv tiv thaiv ib puag ncig. Uas yog hais, TPU lub tsho tiv nag yog ib hom tsho tiv nag uas pej xeem nyiam niaj hnub no.
Vim li cas thiaj xaiv cov khoom siv TPU
TPU lub tsho tiv nag yog ib hom tshiab ntawm kev tiv thaiv ib puag ncig, thiab cov qauv siv hluav taws xob cuam tshuam nrog kev siv tshuab ntawm cov khoom siv los nag. Ua ntej tshaj plaws, cov khoom siv ntawm lub tsho tiv nag yog ua los ntawm cov khoom siv uas lwj tag nrho, kom tsis txhob muaj kuab paug rau ib puag ncig tom qab nws raug pov tseg. Thaum lub tsho tiv nag tsis tuaj yeem siv thiab xav tau pov tseg, nws tuaj yeem faus rau hauv av. Tom qab ib lub sijhawm, cov khoom siv los nag yuav lwj tag nrho, thiab cov noob tuaj yeem tawg thiab loj hlob hauv av los tsim cov nroj tsuag, uas tsis tsuas yog daws qhov teeb meem kev tiv thaiv ib puag ncig ntawm lub tsho tiv nag, tab sis kuj muaj cov txiaj ntsig ntawm kev cog ntoo thiab ntsuab.
