Polyurethane yog cov khoom siv hluav taws xob uas muaj zog, hu ua "Fifth Plastic", thiab tau siv dav hauv ntau lub teb chaws kev lag luam vim nws qhov kev ua tau zoo heev.Tam sim no, Tuam Tshoj yog tus tsim khoom loj tshaj plaws ntawm polyurethane hauv ntiaj teb, suav txog li 45% ntawm lub ntiaj teb polyurethane ntau lawm.Muaj ntau yam khoom siv polyurethane, thiab polyurethane elastomer yog ib qho ntawm lawv.Polyurethane elastomer yog cov khoom siv elastomer uas muaj ntau pawg carbamate ntawm cov saw hlau polymer, thiab nws yog cov khoom siv polymer uas tuaj yeem rov zoo tom qab lub zog sab nraud siv rau nws raug tshem tawm.
Polyurethane elastomers tuaj yeem muab faib ua cov thermoplastic polyurethane elastomers (TPU), cam khwb cia polyurethane elastomers (CPU) thiab sib xyaw polyurethane elastomers (MPU) raws li cov txheej txheem sib txawv, ntawm cov TPU yog qhov loj tshaj plaws.TPU kev lag luam yog ib ceg ntawm polyurethane kev lag luam, nyob rau hauv lub downstream ntawm tag nrho cov chemical kev lag luam saw, ze rau qhov kawg cov neeg siv khoom lag luam.
01 Kev faib tawm ntawm polyurethane elastomers
TPU yog polyurethane elastomer khoom.Cov khoom siv raw xws li polyols, MDI, BDO, adipic acid, thiab ethylene glycol xav tau rau nws cov khoom yog tag nrho cov roj av derivatives los yog cov khoom lag luam, thiab yog cov khoom lag luam qis ntawm petrochemicals.TPU yog ib ceg ntawm cov khoom siv thermoplastic elastomer.Nws yog cov khoom siv polymerized los ntawm peb cov khoom siv raw: diisocyanate, macromolecular polyol, thiab saw extender (tsis tshua muaj molecular diol).
Piv nrog rau cov khoom siv yas thiab roj hmab, TPU muaj ntau yam hardness, zoo heev mechanical zog, zoo heev / tsis kub tsis kam, zoo ua hauj lwm, zoo ib puag ncig kev ua tau zoo, muaj zog plasticity, muaj zog designability, thiab zoo heev transparency.Nws tsis tsuas yog muaj lub siab elasticity ntawm cov ntaub ntawv roj hmab, tab sis kuj muaj lub zog siab ntawm engineering plastics.
02 TPU khoom yam ntxwv
TPU yog thawj zaug ua tiav los ntawm Bayer hauv xyoo 1958, thiab cov tuam txhab tshuaj lom neeg loj hauv Tebchaws Europe thiab Tebchaws Meskas tau tsim ua tiav thiab muab tso rau hauv ntau lawm.Nyob rau xyoo 1970, Nyiv tau tshaj tawm German TPU cov cuab yeej tsim khoom thiab qhia TPU cov cuab yeej tsim khoom rau Taiwan.Tuam Tshoj Mainland tau nthuav tawm TPU ntau lawm tshuab txij li xyoo 1980s, tab sis tsis tau ua tiav kev tshawb fawb thiab kev tsim kho thiab thev naus laus zis.Tom qab xyoo 1990, nrog rau kev lag luam nce ntxiv rau TPU cov ntaub ntawv, tom qab European, Asmeskas thiab Taiwan cov tuam txhab nyiaj txiag nkag mus rau hauv av loj, qee qhov chaw lag luam loj pib tsim thiab muag TPU.
03 Kev txhim kho keeb kwm ntawm kev lag luam thoob ntiaj teb thiab Suav TPU
Ua tsaug rau nws cov khoom lag luam zoo, kev lag luam xav tau TPU hauv ntau lub teb chaws kev lag luam xws li cov khoom siv niaj hnub, kev tsim khoom, kev kho mob, kev tiv thaiv hauv teb chaws thiab kev lag luam tub rog tau nce ntau.Nyob rau hauv xyoo tas los no, kuv lub teb chaws tus tshiab TPU tsim muaj peev xwm tau tso tawm ib tug tom qab lwm, thiab TPU kev khiav hauj lwm tus nqi tau nce tsis tu ncua nyob rau hauv 2018 thiab 2019. Los ntawm 2014 mus rau 2019, lub compound txhua xyoo kev loj hlob tus nqi ntawm domestic TPU ntau lawm yog siab li 15.46%. .Hauv 2019, qhov ntsuas ntawm kuv lub teb chaws TPU kev lag luam txuas ntxiv nthuav dav, nrog rau cov khoom tsim tawm ntawm 512,900 tons.kuv lub teb chaws tau maj mam dhau los ntawm Tebchaws Europe thiab Tebchaws Meskas los ua lub ntiaj teb cov neeg tsim khoom loj tshaj plaws thiab cov neeg siv khoom ntawm TPU, thiab qhov nruab nrab txhua xyoo noj tau khaws cia kev loj hlob sai ntawm li 10%.
04 Daim Ntawv Qhia TPU Ntau Lawm hauv Tuam Tshoj los ntawm 2014 txog 2019
Kev cuam tshuam los ntawm Xiangshui xwm txheej hauv 2019, tsoomfwv tau nrawm kho cov chaw ua si tshuaj lom neeg.Nyob rau tib lub sijhawm, tus nqi hloov pauv ntawm cov khoom siv raw isocyanate nce tus nqi tsim khoom ntawm qee lub tsev me me.Txawm li cas los xij, cov tuam txhab tsim, suav nrog Huafon, BASF, thiab Meirui, txuas ntxiv nthuav lawv cov kab thiab nce ntau lawm, thiab ua kom lawv txoj haujlwm ntawm kev ua lag luam.Kev lag luam concentration tseem nce ntxiv.Ntawm cov khoom siv TPU hauv tsev, Huafon Group thiab Yantai Wanhua tuav cov haujlwm saum toj kawg nkaus hauv kev tsim khoom.
05 Kev faib tawm ntawm Tuam Tshoj tus TPU ntau lawm qauv hauv 2019
Txawm hais tias kuv lub teb chaws lub teb chaws TPU ntau lawm scale yog siab, nws tsis muaj qhov zoo nyob rau hauv subdivided teb.Tshwj xeeb tshaj yog nyob rau hauv nruab nrab-rau-siab-kawg lag luam, multinational tuam txhab uas muag xws li BASF thiab Huntsman muaj zoo heev technology zoo.Los ntawm kev tswj cov qauv zoo, lawv tau txhim kho cov khoom ua tau zoo thiab kev ua tau zoo thaum txo cov nqi tsim khoom, tuav ib feem tseem ceeb ntawm kev lag luam hauv nruab nrab-rau-siab thiab high-end kev lag luam.Tam sim no, feem ntau ntawm cov tuam txhab TPU hauv kuv lub teb chaws tsis muaj qhov zoo ntawm cov thev naus laus zis thev naus laus zis, ib qho khoom tsim qauv, thiab kev nce qib qeeb hauv cov khoom tshiab, ua rau tag nrho cov kev lag luam tsis muaj zog, thiab nws nyuaj rau kev ua lag luam cov txiaj ntsig zoo.
Kev txhim kho kev coj ua, nplai, kev sib tw qauv, kev loj hlob tus nqi, thiab qib nyiaj tau los ntawm TPU kev lag luam ncaj qha nyob ntawm kev xav tau ntawm kev lag luam downstream industries.
Cov ntaub ntawv qhia tau hais tias raws li ib txwm siv roj hmab thiab cov ntaub ntawv yas yog maj mam hloov los ntawm ib puag ncig cov ntaub ntawv, kev noj ntawm TPU yuav loj hlob ntxiv, thiab nws yuav siv dav hauv ntau lub teb chaws kev lag luam.TPU feem ntau yog siv rau hauv cov kav dej, cov yeeb yaj kiab, cov khoom siv hluav taws xob, cov khoom siv khau, qhov chaw pib, hloov kho encapsulation, kev sib kis, cov nplaum nplaum, cov xov hlau thiab cables thiab lwm yam.Ntawm lawv, cov ntaub ntawv khau yog cov neeg siv khoom lag luam tseem ceeb rau TPU, suav txog 40% ntawm TPU noj.
06 Tuam Tshoj TPU downstream daim ntawv thov qauv
kuv lub teb chaws yog lub ntiaj teb loj tshaj plaws tsim thiab exporter ntawm nkawm khau, thiab nws cov zis tso nyiaj rau ntau tshaj 50% ntawm lub ntiaj teb no tag nrho.Kev tsim kho thev naus laus zis ntawm cov khoom siv ib leeg yog qhov tseem ceeb ntawm kev tsim kho tshiab hauv kev lag luam khau.Piv nrog rau cov khoom siv ib txwm siv, TPU muaj qhov pom tseeb zoo hauv kev ua haujlwm, thiab nws cov kev siv tau nce zuj zus ib hnub.Ntawm lawv, ETPU muaj qhov zoo tshaj plaws hauv kev ua haujlwm siab thiab kev poob siab.Qhov ib leeg ua los ntawm nws tuaj yeem nqus tau qhov cuam tshuam ntawm hauv av thiab ntsej muag ntawm ko taw, muab cov nyhuv cushioning zoo.
Ntawm qhov tod tes, TPU kev lag luam muaj cov yam ntxwv ntawm kev faib ua feem ntawm cov khoom siv raw, cov khoom lag luam hloov tshiab ceev, ntau yam tshwj xeeb thiab cov qauv, thiab pom tseeb qhov sib txawv ntawm cov neeg siv khoom xav tau.Yog li ntawd, cov nyiaj tau los ntawm kev lag luam yog cuam tshuam los ntawm ntau yam xws li kev hloov pauv ntawm cov khoom siv raw, kev tsim khoom tshiab, thiab qib kev pabcuam rau cov neeg siv khoom.Nrog rau kev qhia ua tiav ntawm cov cai hauv tsev thiab kev ntsuas tsom rau cov neeg nyob hauv kev noj qab haus huv kev ua kis las, thiab kev txhim kho cov neeg nyob hauv kev noj thiab kev siv nyiaj ntawm cov khoom kis las, kev loj hlob ntawm cov neeg siv khoom xav tau cov khau ncaws pob high-tech yuav pab txhim kho qhov chaw thov ntawm TPU. kev lag luam.Ntawm qhov tod tes, nyob rau hauv lub lag luam high-end Rau ntau yam xws li calendered TPU, kho mob TPU, thiab high-temperature-resistant TPU, lub teb chaws tsuas yog cia siab rau imports.Nrog rau lub sij hawm ntev technology tsub zuj zuj thiab R & D peev ntawm domestic TPU tuam txhab uas muag, nws yuav tsum tau tawg los ntawm monopoly ntawm txawv teb chaws tuam txhab uas muag thiab nthuav lub domestic lwm qhov chaw.
