Polyurethane, cov khoom lag luam tawm tshiab tshaj tawm ntawm polymer polymer, yog lub npe hu ua" thib tsib loj tshaj plaws yas", thiab tau siv dav hauv ntau qhov chaw ntawm kev lag luam hauv lub teb chaws vim nws cov txiaj ntsig zoo. Tam sim no, Tuam Tshoj yog lub ntiaj teb' s tus neeg tsim khoom lag luam loj tshaj plaws ntawm polyurethane, suav txog li 45% ntawm kev lag luam polyurethane thoob ntiaj teb. Muaj ntau ntau cov khoom lag luam polyurethane, thiab polyurethane elastomer yog ib qho ntawm lawv. Polyurethane elastomer yog cov txheej txheem ntawm cov khoom siv elastomer uas muaj ntau cov urethane pawg ntawm cov polymer loj cov saw. Nws yog ib hom ntawm cov khoom siv polymer uas tuaj yeem rov qab tau zoo tom qab lub zog sab nraud thov rau nws yog tshem tawm.
Cov tshuaj tiv thaiv polyurethane elastomers tuaj yeem muab faib ua cov thermoplastic polyurethane elastomers (TPU), castable polyurethane elastomers (CPU) thiab sib xyaw polyurethane elastomers (MPU) raws li cov txheej txheem sib txawv. Ntawm lawv, TPU muaj qhov ntsuas loj tshaj plaws. TPU kev lag luam yog nyob rau hauv qis ntawm tag nrho cov chemical kev lag luam saw, ze rau qhov kawg cov neeg siv khoom lag luam.
1. Kev faib tawm ntawm polyurethane elastomers
TPU yog cov khoom lag luam polyurethane elastomer. Cov ntaub ntawv nyoos xws li polyol, MDI, BDO, adipic acid, ethylene glycol, thiab lwm yam uas xav tau rau nws cov ntau lawm yog txhua yam roj av lossis cov khoom lag luam, uas yog cov khoom lag luam qis ntawm kev lag luam petrochemical. TPU yog ib ceg ntawm thermoplastic elastomer cov khoom. Nws yog cov khoom siv polymer polymerized los ntawm peb cov ntaub ntawv yooj yim: diisocyanate, macromolecular polyol, thiab cov saw extender (qis molecular diol).
Piv nrog rau cov ntaub ntawv yas thiab cov khoom siv roj hmab, TPU muaj cov khoom siv los ntawm cov tawv tawv, cov khoom siv lub tshuab tsis tshua muaj zog, zoo heev / qis kub tsis kam, kev ua haujlwm zoo, kev ua tau zoo ntawm ib puag ncig, yas muaj zog, kev tsim muaj zog, thiab zoo heev pob tshab. Nws muaj ob lub siab elasticity ntawm cov khoom siv roj hmab thiab lub siab muaj zog ntawm engineering plastics.
2. TPU cov yam ntxwv khoom siv
TPU tau tsim ua tiav los ntawm Bayer ntawm lub teb chaws Yelemees xyoo 1958, thiab cov tuam txhab ua tshuaj lom neeg loj hauv Tebchaws Europe thiab Tebchaws Asmeskas tau ua tiav zoo thiab muab tso rau hauv kev tsim khoom. Xyoo 1970, Nyij Pooj qhia kev tsim cov cuab yeej tsim khoom siv TPU thiab kev tsim khoom siv TPU ntau lawm rau Taiwan. Suav Teb Tebchaws tau nthuav tawm rau TPU kev tsim cuab yeej technology txij xyoo 1980s, tab sis tsis tau ua tiav qhov kev sib tawg hauv R& D thiab thev naus laus zis. Tom qab xyoo 1990, raws li qhov kev thov ua lag luam rau TPU cov ntaub ntawv nce, tom qab European, Asmeskas, thiab Taiwan-nyiaj lag luam nkag mus rau hauv thaj av loj, qee cov lag luam loj tau pib tsim thiab muag TPU.
3. Ntiaj teb thiab Tuam Tshoj TPU kev tsim kho keeb kwm kev lag luam
Ua tsaug rau nws cov khoom lag luam zoo, TPU' s kev lag luam xav tau hauv ntau yam kev lag luam hauv teb chaws xws li cov khoom lag luam, kev tsim khoom, kev kho mob thiab kev noj qab haus huv, kev tiv thaiv thiab kev lag luam tub rog tau nce siab dua. Xyoo tsis ntev los no, kuv lub teb chaws' s tshiab TPU kev tsim tawm tau tso tawm ib qho dhau ib qho, thiab TPU cov haujlwm kev lag luam tau nce ntxiv nyob rau xyoo 2018 thiab 2019. Lub xyoo tshiab ntawm kev loj hlob ntawm domestic TPU ntau lawm los ntawm 2014 txog 2019 yog siab txog 15.46%. Hauv 2019, qhov ntsuas ntawm kuv lub teb chaws' s TPU kev lag luam txuas ntxiv nthuav dav, muaj qhov tso zis ntau li 512,900 tons. Kuv lub teb chaws tau maj dhau thoob Tebchaws Europe thiab Tebchaws Meskas dhau los ua lub ntiaj teb' tus neeg TPU loj tshaj plaws thiab tus neeg tau txais kev pabcuam, thiab nws qhov nruab nrab kev noj haus txhua xyoo tau ceev txog 10%.
4. Suav Teb' s TPU downstream daim qauv thov
Kuv lub teb chaws yog lub ntiaj teb' s tus neeg tsim khoom ua khau loj tshaj plaws thiab tus xa tawm, thiab nws cov khoom tso tawm tau ntau tshaj 50% ntawm tag nrho ntiaj teb. Thev naus laus zis thev naus laus zis ntawm cov ntaub ntawv tsuas yog qhov tseem ceeb kev hloov kho hauv kev lag luam khau. Piv nrog cov khau ntaub ib txwm muaj, TPU muaj cov txiaj ntsig kev ua kom tau zoo, thiab nws txoj kev noj tshuaj tau nce hnub zuj zus Ntawm lawv, ETPU muaj kev tiv taus zoo thiab ua rau lub zog nqus tau zoo, thiab cov khoom ua tau zoo tuaj yeem nqus tau qhov cuam tshuam ntawm qhov av ntawm ko taw thiab muab cov txiaj ntsig zoo cushioning.
Ntawm tag nrho, TPU kev lag luam muaj cov yam ntxwv ntawm cov feem ntawm cov nqi ntawm cov khoom siv raw, cov khoom hloov tshiab sai, ntau cov kev qhia tshwj xeeb thiab qauv, thiab cov neeg siv xav tau. Yog li, qib nyiaj tau los ntawm kev lag luam muaj kev cuam tshuam los ntawm ntau yam xws li kev hloov pauv ntawm tus nqi raw khoom, cov peev txheej tsim khoom tshiab, thiab qib kev pabcuam ntawm cov neeg siv khoom. Nrog cov kev qhia ua tiav ntawm cov kev cai hauv tsev thiab kev ntsuas rau cov pej xeem cov kev ua si thiab kev noj qab haus huv, thiab kev txhim kho ntawm cov neeg siv cov neeg siv rau cov khoom siv kis las, kev loj hlob ntawm cov neeg siv khoom xav tau rau cov khau kis las ua kis las siab yog qhov muaj txiaj ntsig zoo los ua qhov chaw thov ntawm TPU kev lag luam Cov. Ntawm qhov tod tes, hauv kev lag luam high-kawg xws li calender qib TPU, kho mob TPU, kub siab tiv thaiv TPU thiab lwm yam ntau yam, lub teb chaws feem ntau tso siab rau kev siv ntshuam. Nrog cov thev naus laus zis thev naus laus zis ntau lawm thiab R& D peev ntawm cov tuam txhab TPU hauv tsev, cia siab yuav ua kom cov neeg tawg rog ntawm cov tuam txhab txawv teb chaws thiab nthuav tawm qhov chaw hloov chaw hauv lub teb chaws.
