Kev Taw Qhia
Hauv cov yeeb yaj kiab tiv thaiv tsheb, cov ntawv lo ntawm cov khoom siv feem ntau zoo ib yam txawm tias thaum cov logic ntawm daim ntawv thov txawv. TPU thiab PCU ob leeg tau tham txog tias yog cov txheej txheem polymer ua haujlwm siab, tab sis tus nqi ntawm txhua yam khoom siv nyob ntawm qhov kev siv zaum kawg. TPU, tshwj xeeb tshaj yog aliphatic TPU, tau muab tso rau qhov chaw dav rau kev tiv thaiv nto vim nws ua ke kev ywj pheej, UV tsis kam, kev tiv thaiv kev sib txhuam, thiab xim ruaj khov. Lubrizol piav qhia txog aliphatic TPU chemistries ua xim ruaj khov thiab tsim nyog rau kev tiv thaiv nto, nrog rau kev sib txhuam thiab khawb tsis kam.
PCU, hauv cov lus lag luam tam sim no, feem ntau siv los piav qhia txog tsev neeg zaj duab xis polyurethane uas ua los ntawm polycarbonate es tsis yog pawg tiv thaiv sib cais kiag li. Kev tshawb fawb txog polycarbonate mos mos uas ua los ntawm polyurethane qhia tau hais tias cov kab ke no tuaj yeem xa cov khoom siv kho tshuab muaj zog thiab hydrolytic stability, uas piav qhia vim li cas polycarbonate chemistry thiaj li nyiam siv rau hauv cov ntawv thov polymer uas xav tau. Lo lus nug hauv zaj duab xis tsheb tsis yog seb PCU puas tuaj yeem ua haujlwm tau, tab sis seb nws puas yog qhov zoo tshaj plaws rau qhov xav tau ntawm qhov muag, qhov chaw, thiab kev ruaj khov ntawm kev siv tsheb tiag tiag.
TPU thiab PCU Txhais Li Cas hauv Cov Khoom Siv Architecture
TPU yog ib tsev neeg thermoplastic polyurethane uas muaj cov khoom sib cais. Nws cov khoom nyob ntawm seb cov khoom mos thiab cov khoom tawv sib txawv li cas, uas txhais tau tias TPU tuaj yeem hloov kho kom haum rau ntau yam kev sib npaug ntawm kev ywj pheej, kev pom tseeb, kev rov qab los, thiab kev ruaj khov. Cov kev tshuaj xyuas kev kawm piav qhia txog TPU ua ib chav kawm khoom siv uas muaj kev ua haujlwm zoo thiab muaj kev sib npaug ntawm kev ywj pheej thiab kev tawv, thaum Lubrizol qhia txog ntau yam kev xaiv tawv thiab kev tiv thaiv qhov chaw.
PCU, thaum siv rau hauvcov xim pleev xim rau tshebkev ua lag luam, feem ntau yog khi rau polycarbonate-raws li polyurethane chemistry. Polycarbonate mos segment-based PU tau tshaj tawm tias qhia txog kev ua tau zoo heev thiab hydrolytic stability, thiab polycarbonate macrodiols tau cuam tshuam nrog kev txhim kho theem miscibility thiab tensile tus cwj pwm hauv segmented polyurethane systems. Qhov ntawd txhais tau tias PCU tuaj yeem ntseeg tau. Qhov teeb meem tseem ceeb yog tias kev ntseeg tau ib leeg tsis ua rau nws yog lub platform zaj duab xis zoo tshaj plaws rau kev tiv thaiv sab nraud tsheb.
Vim li cas TPU feem ntau haum rau Automotive Film zoo dua
Cov yeeb yaj kiab tsheb raug txiav txim los ntawm ntau tshaj li cov tshuaj polymer. Nws yuav tsum nyob twj ywm, tiv taus khawb, tiv taus UV, thiab tseem ruaj khov tom qab kev teeb tsa. Lubrizol tso aliphatic TPU ua ib qho kev xaiv zoo rau kev tiv thaiv qhov chaw vim nws muaj kev tiv thaiv UV, kev puas tsuaj thiab khawb mus sij hawm ntev, thiab kev ruaj khov xim hauv cov ntawv thov kom pom tseeb lossis xim sib dua. Cov no yog cov yam ntxwv tseem ceeb hauv cov yeeb yaj kiab tiv thaiv xim, cov yeeb yaj kiab tiv thaiv lub qhov rais, thiab lwm yam khoom siv hauv tsheb.
TPU kuj muaj keeb kwm siv dav dua hauv cov yeeb yaj kiab tiv thaiv, yog li kev ua lag luam muaj kev paub ntau dua txog kev tsim cov qauv, kev sib raug zoo ntawm cov txheej, thiab kev khaws cia ntev. Hauv kev xyaum, qhov ntawd txhais tau tias cov yeeb yaj kiab raws li TPU feem ntau yooj yim dua rau kev tso thaum qhov meej, kev ruaj khov, thiab qhov zoo ntawm qhov chaw txhua yam tseem ceeb tib lub sijhawm. Rau kev siv tsheb, qhov no yog qhov zoo dua vim tias cov khoom tsis yog tsuas yog daim ntawv polymer xwb; nws yog ib txheej txheej uas yuav tsum zoo nkauj thiab ua haujlwm tas li ntawm cov chaw tsheb tiag tiag.
Qhov twg PCU tuaj yeem pab tau, thiab vim li cas nws tseem muaj kev sib pauv pauv
PCU tsis yog tsis muaj qhov zoo. Cov txheej txheem PU ua los ntawm polycarbonate tuaj yeem muab cov khoom siv kho tshuab zoo thiab kev ruaj khov hydrolytic, uas ua rau lawv zoo nkauj hauv cov chaw uas qhov kev tiv thaiv dej noo thiab lub zog polymer yog qhov tseem ceeb. Qee zaum, qhov no tuaj yeem muaj txiaj ntsig zoo rau cov ntawv thov tshwj xeeb lossis cov yeeb yaj kiab tsim uas cov qauv tshuaj lom neeg yog qhov tseem ceeb.
Qhov kev pauv pauv yog tias zaj duab xis tsheb tsis yog tsuas yog ua kom zoo dua nyob ib puag ncig hydrolytic stability. Ib zaj duab xis uas tig mus rau lub tsheb kuj yuav tsum tswj hwm qhov tsis muaj teeb meem ntawm qhov muag, tiv taus kev hnav ntawm qhov chaw, thiab khaws cov duab pom kev huv si hauv qab lub hnub ci thiab kev ntxuav dua. TPU yog sib phim ncaj qha nrog cov kev xav tau ntawd. Los ntawm qhov sib piv, polycaprolactone-based polyurethane systems, uas yog lwm tsev neeg mos mos hauv kev sib tham no, muaj nqis rau kev ywj pheej thiab biodegradability, tab sis cov yam ntxwv ntawd muaj txiaj ntsig zoo dua hauv kev siv biomedical lossis cov khoom siv ruaj khov dua li hauv kev tiv thaiv sab nraud lub tsheb ntev. Qee cov yeeb yaj kiab PCL-based polyurethane kuj tau tshaj tawm tias muaj kev cuam tshuam rau hydrolytic degradation, uas qhia meej tias cov khoom siv lub zog hauv ib qho teb tsis ua rau nws yog qhov kev xaiv zoo tshaj plaws rau lwm qhov.
Kev Sib Piv Raws Li Daim Ntawv Thov
Los ntawm qhov pom ntawm daim ntawv thov, TPU feem ntau yog qhov kev xaiv zoo dua rau cov yeeb yaj kiab tsheb vim nws sib haum zoo dua nrog cov khoom ua tau zoo tiag tiag uas xav tau ntawm cov tsheb. Cov khoom ntawd suav nrog kev ruaj khov UV, kev tiv thaiv khawb, kev pom tseeb ntawm qhov muag, kev ywj pheej thaum lub sijhawm teeb tsa, thiab kev khaws cia ntev. Aliphatic TPU tau tshaj tawm tshwj xeeb rau cov khoom no hauv kev siv tiv thaiv nto, yog vim li cas nws thiaj li raug kho dav dav ua cov khoom siv rau cov yeeb yaj kiab tsheb zoo tshaj plaws.
PCU tseem yuav muaj txiaj ntsig thaum ib qhov project muab qhov tseem ceeb rau qee yam khoom polymer xws li hydrolytic stability lossis kev coj cwj pwm tshwj xeeb. Tab sis rau zaj duab xis sab nraud ntawm lub tsheb, lo lus nug tseem ceeb yog kev ua tau zoo ntawm iav lossis xim, tsis yog lub npe tsev neeg polymer nyoos. Hauv qhov kev nkag siab ntawd, TPU feem ntau yeej vim tias kev lag luam twb tau tsim cov kev daws teeb meem uas laus dua, npaj txhij rau kev siv nyob ib puag ncig nws.
Xaus lus
TPU thiab PCU yog ob qho tib si cov khoom siv tseem ceeb hauv kev siv tshuab, tab sis lawv tsis tau zoo sib xws rau tib yam haujlwm hauv tsheb. PCU tuaj yeem muab cov yam ntxwv kho tshuab thiab hydrolytic muaj zog, tsis tau TPU, tshwj xeeb tshaj yog aliphatic TPU, zoo dua rau qhov xav tau ntawm cov yeeb yaj kiab tiv thaiv tsheb vim nws ua ke qhov tseeb, tiv taus UV, tiv taus khawb, thiab xim ruaj khov ntev. Rau txhua yam car qhov rais tint chaw tsim khoom, qhov kev xaiv muaj zog dua feem ntau yog qhov ua tau zoo tshaj plaws hauv qhov chaw tiag tiag, tsis yog qhov uas zoo li siab dua ntawm daim ntawv qhia tshwj xeeb. Hauv qhov kev sib piv ntawd, TPU tseem yog lub platform khoom siv uas tau lees paub ntau dua rau cov khoom siv zaj duab xis zoo tshaj plaws.
