High-end polypropylene hais txog cov khoom siv polypropylene ntxiv rau cov khoom siv dav dav (kos duab, qis yaj copolymerization, homopolymer txhaj tshuaj molding, fiber ntau, thiab lwm yam), suav nrog tab sis tsis txwv rau cov ntaub ntawv pob tshab, CPP, cov ntaub ntawv raj, peb cov khoom siab.
Nyob rau hauv xyoo tas los no, high-end polypropylene tau dhau los ua ib qho kev sib ntaus sib tua, high-end PP muaj peev xwm tsim tau ntxiv, foaming polypropylene, metallocene polypropylene, peb high polypropylene, ultra-low tshauv polypropylene thiab lwm yam tshiab ntau yam ntawm kev ua lag luam sib koom yog tsawg, tab sis qhov chaw thov yog dav, lub neej yav tom ntej kev lag luam kev loj hlob muaj peev xwm loj;Los ntawm 2021, cov zis ntawm high-end polypropylene mus txog 7,963,400 tons, ntshuam ntim yog 2,399,100 tons, thiab cov ntshuam dependence mus txog 23.57%.Qee cov khoom lag luam tab tom ntsib cov xwm txheej txawv teb chaws monopoly thiab tab tom dhau los ntawm cov txheej txheem pib los ntawm kos.Lub sijhawm ntawm 2021-2025 yog lub sijhawm loj hlob ntawm high-end polypropylene, thiab kev loj hlob yuav qeeb hauv 2025-2030.
Thaum lub sijhawm xyoo 2022-2030, 35.63 lab tons / xyoo ntawm kev teeb tsa polypropylene tau npaj yuav muab tso rau hauv kev lag luam hauv Suav teb, tab sis high-end polypropylene tsuas yog kwv yees li 30% ntawm cov peev txheej tshiab polypropylene, yog li nws yog kwv yees li 10.7 lab. tons.Ntxiv rau ib feem ntawm PDH cov txheej txheem kev lag luam, vim tias nws cov khoom siv ethylene tsis tuaj yeem tsim cov polymers nkaus xwb, nws yuav tsis raug cais rau hauv cov qib high-end polypropylene hauv lub sijhawm luv luv, thiab ib feem ntawm cov thee refining tshuaj thiab lwm yam khoom siv, vim tias cov txheej txheem tshiab ntawm cov cuab yeej tsis ruaj khov, thev naus laus zis tsis paub tab thiab lwm yam laj thawj ua rau kev ua kom zoo dua qub thiab cov thee tshuaj lom neeg kev lag luam ruaj khov, yog li cov ntaub ntawv dav dav xws li hlau kos duab qis melting copolymerization ntaus lub lag luam, nws tsis raug cais raws li high-end polypropylene. rau lub sijhawm;Yav tom ntej, Sinopec thiab CNPC yuav nthuav dav ntau lub peev xwm vim lawv cov keeb kwm nplua nuj thiab cov txheej txheem ruaj khov.Lawv qhov kev teeb tsa tsom mus rau qhov kev xav tau ntawm kev lag luam high-end.Nyob rau hauv lub neej yav tom ntej, kev sib tw rau high-end polypropylene yuav txuas ntxiv mus ncig ntawm ob lub roj.
Nyob rau hauv cov nqe lus ntawm kev thov, high-end polypropylene yog tam sim no nyob rau hauv qhov loj tshaj plaws thov rau kev hloov tsheb.Txoj kev loj hlob sai ntawm automotive lub teeb yuag lub tswv yim thiab lub zog tshiab tsheb tau muab qhov tseem ceeb dua rau kev hloov kho tsheb ua lag luam.Lub ntsiab lus xav tau kev loj hlob yog nruab nrab-siab fusion copolymerization.Qhov thib ob yog nyias phab ntsa txhaj molding.Takeout ntim tau muab tso rau hauv kev coj noj coj ua.Kev lag luam nqa tawm tau tsim tshwj xeeb sai raws li kev pabcuam kev noj qab haus huv rau pej xeem.Qhov kev loj hlob deb tshaj qhov kev loj hlob tag nrho ntawm polypropylene thov.Kev lag luam pob tshab yog siv dav thiab muaj kev cia siab dav.Nws yog tsuas yog siv rau hauv cov hnab ntim tshuaj kho mob, cov khoom siv kho mob, cov thawv ntim khoom, cov khoom siv me nyuam mos, thiab lwm yam. Ntawm lawv, cov pob tshab kho mob suav txog li 40% ntawm tag nrho cov pob tshab, ua raws li cov thawv ntim khoom.Vim muaj qhov tshwm sim ntawm kev laus hauv Suav teb thiab qhov xwm txheej ntawm ib txwm muaj kev sib kis, pob tshab hlau yuav tsum tau txhim kho, thiab tam sim no kev lag luam pob tshab hauv tsev yog nyob ntawm kev xa khoom, yog li tseem muaj qhov chaw loj rau kev txhim kho kev lag luam hauv tsev yav tom ntej.Thaum kawg, cov khoom siv high-end xws li binary thiab ternary copolymerization CPP zaj duab xis thiab cov yeeb nkab dej kub tau txwv hauv kev lag luam vim lawv lub peev xwm ua lag luam me thiab kev ua haujlwm tsawg.Cov khoom siv hauv tsev tsuas tuaj yeem suav txog li 50% ntawm kev ua lag luam, thiab tseem muaj qhov chaw loj rau kev ua si hauv kev lag luam hauv tsev.Txhawm rau ua kom tiav, kev loj hlob yav tom ntej ntawm high-end polypropylene muaj peev xwm nthuav dav yog tsawg dua li tag nrho kev lag luam siab ntawm polypropylene, thiab kev lag luam xav tau tseem muaj qhov chaw loj rau kev txhim kho, yav tom ntej layout ntawm high-end polypropylene kev tshawb fawb thiab kev tsim khoom yog yuav tsum tau.
