Qhov sib txawv ntawm TPU polyester thiab polyether, thiab kev sib raug zoo ntawm polycaprolactone thiab TPU

Qhov sib txawv ntawm TPU polyester thiab polyether, thiab kev sib raug zoo ntawmpolycaprolactone TPU

Ua ntej, qhov sib txawv ntawm TPU polyester thiab polyether

Thermoplastic polyurethane (TPU) yog ib hom khoom siv elastomer ua tau zoo, uas siv dav hauv ntau qhov chaw. Raws li cov qauv sib txawv ntawm nws cov ntu mos, TPU tuaj yeem muab faib ua hom polyester thiab hom polyether. Muaj qhov sib txawv tseem ceeb hauv kev ua tau zoo thiab daim ntawv thov ntawm ob hom.

Polyester TPU muaj lub zog siab thiab hnav tsis kam, cov khoom tensile, cov khoom khoov thiab cov kuab tshuaj tiv thaiv zoo heev. Tsis tas li ntawd, nws muaj kev tiv thaiv kub zoo thiab tsim nyog rau kev siv hauv qhov chaw kub siab. Txawm li cas los xij, qhov tsis kam hydrolysis ntawm polyester TPU tsis zoo, thiab nws yooj yim rau cov dej molecules nkag thiab tawg.

Nyob rau hauv kev sib piv,TPU polyetherNws lub zog siab, tsis kam rau hydrolysis thiab resilience siab. Nws qhov kev ua haujlwm kub qis kuj zoo heev, tsim nyog rau kev siv hauv qhov chaw txias. Txawm li cas los xij, lub zog tev tawm thiab lub zog tawg ntawm polyether TPU tsis muaj zog heev, thiab qhov tensile, hnav thiab tsim kua muag ntawm polyether TPU kuj qis dua li ntawm polyester TPU.

Qhov thib ob, polycaprolactone TPU

Polycaprolactone (PCL) yog cov khoom siv polymer tshwj xeeb, thaum TPU luv rau thermoplastic polyurethane. Txawm hais tias lawv ob leeg yog cov khoom siv polymer, polycaprolactone nws tus kheej tsis yog TPU. Txawm li cas los xij, hauv cov txheej txheem tsim khoom ntawm TPU, polycaprolactone tuaj yeem siv ua cov khoom tseem ceeb ntawm cov khoom mos mos los cuam tshuam nrog isocyanate los tsim TPU elastomers nrog cov khoom zoo heev.

Qhov thib peb, kev sib raug zoo ntawm polycaprolactone thiabTPU masterbatch

Masterbatch ua lub luag haujlwm tseem ceeb hauv kev tsim TPU. Masterbatch yog cov prepolymer uas muaj cov concentration siab, feem ntau yog ua los ntawm ntau yam khoom xws li polymer, plasticizer, stabilizer, thiab lwm yam. Hauv cov txheej txheem tsim TPU, masterbatch tuaj yeem ua rau muaj kev cuam tshuam nrog cov saw hlau txuas, tus neeg sawv cev sib txuas, thiab lwm yam, los tsim cov khoom TPU nrog cov yam ntxwv tshwj xeeb.

Ua ib yam khoom siv polymer ua tau zoo, polycaprolactone feem ntau siv ua ib qho tseem ceeb ntawm TPU masterbatch. Los ntawm kev ua ntej ntawm polycaprolactone nrog lwm cov khoom, cov khoom TPU uas muaj cov khoom siv zoo heev, tsis kam hydrolysis thiab tsis kam kub qis tuaj yeem npaj tau. Cov khoom no muaj ntau yam kev cia siab rau kev siv hauv cov khaub ncaws tsis pom, cov khoom siv kho mob, khau kis las thiab lwm yam.

Plaub, cov yam ntxwv thiab daim ntawv thov ntawm polycaprolactone TPU

Polycaprolactone TPU xav txog qhov zoo ntawm polyester thiab polyether TPU, thiab muaj cov khoom zoo dua. Nws tsis tsuas yog muaj lub zog siab thiab hnav tsis kam, tab sis kuj qhia tau tias muaj kev tiv thaiv hydrolysis zoo thiab tsis kub tsawg. Qhov no ua rau polycaprolactone TPU muaj lub neej ntev thiab ruaj khov hauv cov chaw nyuaj thiab hloov pauv.

Hauv kev lag luam ntawm cov khaub ncaws tsis pom, polycaprolactone TPU tau dhau los ua cov khoom siv nyiam vim nws cov khoom zoo heev. Nws tuaj yeem tiv taus kev yaig ntawm cov yam ntxwv sab nraud xws li nag kua qaub, hmoov av, quav noog, thiab xyuas kom meej tias cov khaub ncaws tsheb ua haujlwm tau zoo thiab lub neej ntev. Tsis tas li ntawd, hauv kev lag luam ntawm cov khoom siv kho mob, cov khoom siv kis las, thiab lwm yam, polycaprolactone TPU kuj tau txais kev saib xyuas dav dav rau nws txoj kev nyab xeeb thiab kev ntseeg siab.

Hauv ntej, muaj qhov sib txawv tseem ceeb ntawm TPU polyester thiab polyether hauv kev ua tau zoo thiab daim ntawv thov, thaum polycaprolactone, ua ib qho ntawm cov khoom tseem ceeb ntawm TPU, muab cov khoom TPU zoo heev. Los ntawm kev nkag siab tob txog kev sib raug zoo thiab cov yam ntxwv ntawm cov ntaub ntawv no, peb tuaj yeem xaiv thiab siv cov khoom TPU tsim nyog kom tau raws li qhov xav tau ntawm ntau qhov chaw sib txawv.
