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 kev ua haujlwm siab elastomer khoom, uas yog dav siv nyob rau hauv ntau yam teb. 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 haujlwm thiab kev siv ntawm ob hom.
Polyester TPU muaj zog thiab hnav tsis kam, tensile zog, khoov zog thiab hnyav kuj zoo heev. Tsis tas li ntawd, nws muaj qhov kub thiab txias ua haujlwm zoo thiab tsim nyog rau kev siv hauv qhov kub thiab txias. Txawm li cas los xij, hydrolysis tsis kam ntawm polyester TPU yog qhov tsis zoo, thiab nws yooj yim rau invaded los ntawm dej molecules thiab tawg.
Piv txwv li,Polyether TPUyog paub txog nws lub zog siab, hydrolysis tsis kam thiab siab resilience. Nws qhov kev ua haujlwm kub qis kuj zoo heev, haum rau siv nyob rau hauv qhov chaw txias. Txawm li cas los xij, lub zog tev thiab tawg lub zog ntawm polyether TPU yog qhov tsis muaj zog, thiab tensile, hnav thiab kua muag tsis kam ntawm polyether TPU kuj qis dua li ntawm polyester TPU.
Thib ob, polycaprolactone TPU
Polycaprolactone (PCL) yog cov khoom siv tshwj xeeb polymer, thaum TPU luv luv rau thermoplastic polyurethane. Txawm hais tias lawv yog ob qho 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 los ua ib qho tseem ceeb ntawm cov khoom muag kom hnov mob nrog isocyanate los tsim TPU elastomers nrog cov khoom zoo heev.
Thib peb, kev sib raug zoo ntawm polycaprolactone thiabTPU masterbatch
Masterbatch plays lub luag haujlwm tseem ceeb hauv kev tsim TPU. Masterbatch yog high-concentration prepolymer, feem ntau yog tsim los ntawm ntau yam khoom xws li polymer, plasticizer, stabilizer, thiab lwm yam. Nyob rau hauv cov txheej txheem ntau lawm ntawm TPU, masterbatch tuaj yeem hnov mob nrog saw extender, crosslinking agent, thiab lwm yam, los tsim cov khoom TPU nrog cov khoom tshwj xeeb.
Raws li cov khoom siv polymer ua haujlwm siab, polycaprolactone feem ntau yog siv los ua ib qho tseem ceeb ntawm TPU masterbatch. Los ntawm prepolymerization ntawm polycaprolactone nrog rau lwm cov khoom, TPU cov khoom uas muaj cov khoom siv zoo heev, hydrolysis tsis kam thiab kub tsis kam tuaj yeem npaj tau. Cov khoom lag luam no muaj ntau yam kev thov kev cia siab nyob rau hauv thaj chaw ntawm cov khaub ncaws tsis pom, khoom siv kho mob, khau kis las thiab lwm yam.
Plaub, cov yam ntxwv thiab kev siv ntawm polycaprolactone TPU
Polycaprolactone TPU coj mus rau hauv tus account qhov zoo ntawm polyester thiab polyether TPU, thiab muaj cov khoom zoo dua. Nws tsis tsuas yog muaj zog txhua yam thiab hnav tsis kam, tab sis kuj qhia tau zoo hydrolysis tsis kam thiab kub tsis kam. Qhov no ua rau polycaprolactone TPU muaj lub neej ntev kev pab cuam thiab ruaj khov nyob rau hauv complex thiab hloov tau.
Hauv thaj chaw ntawm cov khaub ncaws tsis pom, polycaprolactone TPU tau dhau los ua cov khoom nyiam vim nws cov khoom zoo heev. Nws tuaj yeem tiv taus qhov yaig ntawm lwm yam xws li cov kua qaub los nag, plua plav, noog poob, thiab xyuas kom muaj kev ua tau zoo thiab lub neej ntawm lub tsheb khaub ncaws. Tsis tas li ntawd, nyob rau hauv 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 tau.
Hauv luv luv, muaj qhov sib txawv tseem ceeb ntawm TPU polyester thiab polyether hauv kev ua haujlwm thiab kev siv, thaum polycaprolactone, uas yog ib qho tseem ceeb ntawm TPU, muab TPU cov khoom zoo tshaj plaws. 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 tsim nyog TPU kom tau raws li qhov xav tau ntawm ntau qhov chaw.
