Nyob rau hauv xyoo tas los no, tau tsav los ntawm kev loj hlob sai ntawm txoj kev loj thauj neeg caij tsheb thiab tsheb thauj neeg pej xeem hauv nroog, kev tsim tsheb npav tau hloov zuj zus dhau los tsuas yog ua qhov tseem ceeb ntawm kev tsav tsheb kev nyab xeeb thiab kev caij nkoj mus rau qhov tseem ceeb dua rau kev nplij siab, kav ntev, thiab eco- kev phooj ywg ntawm cov khoom sab hauv. Nyob nruab nrab ntawm cov qauv no, TPU/ABS cov khoom sib xyaw- txawv ntawm lawv cov txiaj ntsig kev ua tau zoo- tau maj mam hloov cov khoom siv xws li yas thiab hlau los ua qhov kev xaiv zoo tshaj plaws rau cov tsheb npav sab hauv. Kev siv dav hauv cov khoom tseem ceeb xws li dashboards, qhov rooj vaj huam sib luag, rooj zaum backrests, chaw cia khoom, thiab armrests, cov kev sib xyaw no tau pom lawv daim ntawv thov sib faib nce xyoo dhau los, tawm los ua ib qho tseem ceeb ntawm kev tsav tsheb thauj mus los.
Qhov nce ntawm TPU / ABS cov khoom sib xyaw yog tsim los ntawm lawv lub peev xwm los ua kom muaj kev sib koom ua ke ntawm qhov muaj zog ntawm ob cov khoom siv. ABS nws tus kheej muaj qhov zoo heev rigidity, seem stability, thiab processability, tso cai rau qhov yooj yim fabrication ntawm complex sab hauv duab ntawm tus nqi qis; yog li ntawd, nws tau ntev ua tus qauv xaiv ntawm cov khoom siv sab hauv ib txwm muaj. Txawm li cas los xij, nws raug kev txom nyem los ntawm cov kev txwv tsis pub muaj, suav nrog brittleness ntawm qhov kub thiab txias, qhov tsis zoo ntawm qhov tsis zoo, thiab tsis muaj zog txaus, uas tuaj yeem ua rau muaj teeb meem xws li tawg thiab khawb thaum siv ntev. TPU, conversely, boasts tshwj xeeb toughness, elasticity, khawb kuj, thiab tsawg-kub resilience; nws tswj kev ua haujlwm ruaj khov txawm tias nyob rau hauv qhov chaw txias heev- nqes mus rau -40℃-tsis ua nkig lossis tawg, thaum tseem muaj kev tiv thaiv zoo rau cov roj, tshuaj, thiab kev laus. Los ntawm kev sib xyaw thiab hloov kho ob cov ntaub ntawv no, lawv cov kev tsis txaus ntseeg tau raug txo kom zoo. Cov khoom sib xyaw ua ke khaws cov rigidity thiab yooj yim ntawm kev ua cov yam ntxwv ntawm ABS thaum tib lub sij hawm sib koom ua ke ntawm qhov toughness thiab durability ntawm TPU; Qhov tseem ceeb, nws qhov kev cuam tshuam lub zog tau txhim kho los ntawm ntau dua 30% piv rau ABS ntshiab, yog li txuas ntxiv kev pabcuam lub neej ntawm cov khoom siv sab hauv.
Hais txog cov kev cai tseem ceeb ntawm lub tsheb npav sab hauv-npe muaj kev nyab xeeb thiab kev nplij siab-TPU/ABS cov khoom sib xyaw ua kom pom kev ua tau zoo tshwj xeeb. Ntawm ib sab tes, cov khoom yog tus yam ntxwv los ntawm nws tsis yog - lom, eco- tus phooj ywg xwm thiab tsawg VOC (Volatile Organic Compound) emissions. Tsis pub dawb los ntawm cov khoom siv phom sij xws li plasticizers thiab phthalates, nws ua raws li lub teb chaws ib puag ncig cov qauv rau tsheb sab hauv. Los ntawm kev txo qis kev tso pa tawm ntawm cov pa phem hauv lub tsev, nws tiv thaiv kev noj qab haus huv thiab kev noj qab haus huv - yog cov neeg caij tsheb thiab cov neeg tsav tsheb -ib qho tshwj xeeb ntawm cov tsheb npav hauv nroog thiab cov tsheb thauj mus los ntev -, uas nquag ua haujlwm nyob rau hauv ib puag ncig rau lub sijhawm ntev. Ntawm qhov tod tes, nws qhov chaw tuaj yeem ua tiav kom muaj qhov muag me me, muag muag - kov kev ntxhib los mos uas zoo rau qhov kov; piv rau cov yas tawv tawv, qhov no ua rau muaj txiaj ntsig zoo rau cov neeg caij tsheb. Tsis tas li ntawd, cov khoom muaj suab nrov zoo heev-txo thiab tiv thaiv- cov khoom plam, txo qis kev sib txhuam- ua kom nrov nrov ntawm cov khoom siv sab hauv thaum caij tsheb thauj mus los thiab txo cov kev pheej hmoo ntawm cov neeg caij tsheb zawv zawg ntawm txoj kev tsis zoo, yog li ntxiv kev txhawb nqa tag nrho kev nplij siab.
Los ntawm qhov kev xav ntawm kev siv tswv yim kev lag luam thiab kev tswj hwm tus nqi, TPU / ABS cov khoom kuj muaj qhov zoo tsis tuaj yeem hloov tau. Tau tshaj ntau yam kev ua haujlwm tseem ceeb- xws li lub tshuab nqus tsev thermoforming, txhaj tshuaj molding, thiab extrusion- lawv khav theeb siab molding efficiency thiab siab yield tus nqi. Qhov no muaj peev xwm ua tau raws li qhov xav tau ntawm kev tsim khoom loj ntawm cov khoom siv hauv tsheb npav sab hauv, txo cov nqi ua haujlwm rau cov tuam txhab. Ntxiv mus, cov khoom siv qhov ceev tsuas yog 1.1-1.2 g / cm³, qis dua li cov hlau tsoos thiab qee cov yas tawv. Qhov no ua tau zoo txo qhov hnyav tag nrho ntawm lub tsheb npav lub cev, ua kom yooj yim rau lub tsheb sib zog pib pib- uas, dhau los, txo qis roj noj thiab tso pa tawm- yog li ua kom zoo nrog kev txhim kho ntawm cov tsheb npav tshiab. Piv rau cov ntaub ntawv ntshiab TPU, TPU / ABS cov khoom sib xyaw muab tus nqi txo ntawm 20% -30%; los ntawm kev ntsuas kev lag luam muaj txiaj ntsig zoo nrog cov txiaj ntsig siv tau thaum tswj kev ua haujlwm ncaj ncees, lawv tau txais txiaj ntsig zoo ntawm ntau lub tuam txhab tsheb npav.
Raws li kev lag luam tsheb npav tau hloov pauv mus rau qhov siab dua - kawg, eco- tus phooj ywg, thiab cov kev daws teeb meem ntse, cov kev xav tau rau cov khoom siv sab hauv tau teeb tsa kom nruj dua. Kev siv nws cov txiaj ntsig zoo- suav nrog kev sib xyaw ua ke ntawm kev nruj thiab yoog raws, durability, kev nyab xeeb, eco-kev phooj ywg, thiab tus nqi-kev ua tau zoo-TPU/ABS cov khoom sib xyaw zoo kawg nkaus ua kom tau raws li qhov xav tau ntawm lub tsheb npav sab hauv, thiab nws qhov kev nthuav dav ntxiv. Saib tom ntej, raws li kev hloov kho thev naus laus zis tau dhau los ua qhov tsis tu ncua, TPU / ABS cov khoom sib xyaw yuav tsum ua tiav kev ua tiav ntxiv hauv kev ua tau zoo, txhaj lub zog tshiab rau hauv siab - kev txhim kho zoo ntawm kev lag luam tsheb npav sab hauv.
