Artificial tawv yog ib yam khoom yas, uas zoo li tawv thiab hloov tau.Feem ntau raws li ntaub, coated nrog hluavtaws cob thiab ntau yam yas.PVC tawv tawv, PU hluavtaws tawv.
Feem ntau, raws li cov ntaub, cov khoom yog tau los ntawm txheej los yog txheej txheej ntawm resin sib tov rau nws, ces cua sov, plasticizing, dov los yog embossing.Zoo ib yam li ntuj tawv, nws yog mos thiab hnav-resistant.Raws li hom npog, muaj khau, hnab, thiab lwm yam.
Hauv Suav teb, tib neeg siv los siv.Lub kiv puag ncig khoom tsim los ntawm PVC resin yog hu ua PVC tawv tawv (tom qab no hu ua tawv tawv);siv;Lub kiv puag ncig khoom tsim los ntawm PU resin yog hu ua PU tawv tawv (PU tawv luv luv): lub kiv puag ncig tsim los ntawm PU resin thiab cov ntaub tsis-woven yog hu ua PU hluavtaws tawv (synthetic tawv luv).
Nyob rau hauv xyoo tas los no, lub ntiaj teb cov tawv tawv thiab hluavtaws tawv kev lag luam chaw tau maj mam hloov mus rau Tuam Tshoj, uas tau txhawb txoj kev loj hlob sai ntawm Tuam Tshoj cov tawv tawv thiab hluavtaws tawv kev lag luam.Nyob rau hauv ob xyoos tom ntej no, qhov kev thov tshiab ntawm cov tawv tawv thiab hluavtaws tawv kev lag luam feem ntau yog los ntawm kev lag luam hauv tsev, thiab qhov kev thov loj hlob ntawm kev lag luam downstream yuav yog li ntawm 15%.Ntawm cov tawv tawv thiab hluavtaws tawv, khau tawv tawv, rooj tog tawv tawv thiab tsheb sab hauv tawv tawv yuav yog cov chaw tseem ceeb, thiab cov khoom ua si tub rog thiab cov khoom siv tshwj xeeb thiab lwm yam kev tshwm sim.

Los ntawm qhov kev xav ntawm cov ntaub ntawv downstream, khau tawv, ris tsho tawv, rooj tog tawv tawv thiab lub hnab tawv nqaij yuav yog plaub qhov chaw saum toj kawg nkaus ntawm tawv substrate daim ntawv thov nyob rau hauv Suav teb xyoo 2020. Ntawm lawv, khau tawv yog daim ntawv thov teb nrog cov khoom loj tshaj plaws ntawm cov tawv nqaij. puag daim ntaub hauv Suav teb, txog li 509000 tons, suav txog 36.86%;Ua raws li cov khaub ncaws tawv, rooj tog tawv tawv thiab lub hnab tawv tawv, suav txog 17.60%, 17.45% thiab 14.99% raws li.
Txog rau tam sim no, muaj txog 549 lub tuam txhab loj ntawm cov tawv hluavtaws hauv Suav teb.Tag nrho cov peev txheej ntawm tsib lub tuam txhab tsim khoom hauv cov kab ntau lawm suav txog li 6% ntawm tag nrho cov peev txheej.Kev lag luam concentration ntawm hluavtaws tawv tsis siab.Cov lag luam hauv kev lag luam yeej ua raws li kev lag luam hauv paus ntsiab lus, tso siab rau cov cuab yeej technology, hom, nplai, thiab lwm yam kom muaj kev sib tw hauv kev lag luam, thiab kev lag luam muaj kev lag luam siab.
Txoj kev loj hlob ntawm Synthetic Tawv
Nyob rau hauv xyoo tas los no, kev sib tw hauv kev lag luam hauv tsev PU hluavtaws tawv tau nce zuj zus, thiab kev lag luam tab tom ntsib kev hloov pauv thiab hloov pauv vim qhov nce qis hauv kev lag luam hauv tsev, kev xav tau qis qis, thiab kev xav tau nruj ntxiv rau kev nyab xeeb, kev tiv thaiv ib puag ncig thiab kev ua haujlwm. noj qab haus huv.Kev lag luam tau nkag mus rau theem ntawm kev hloov kho qhov tob, nrog pom tseeb polarization thiab ntxiv kev lag luam concentration.Txij li xyoo 2016, kev saib xyuas kev tiv thaiv ib puag ncig thiab kev tshuaj xyuas kev nyab xeeb tau muab tso rau hauv kev xav tau ntau dua rau kev nyab xeeb thiab kev tsim ntsuab ntawm kev lag luam.Kev ua lag luam tau nkag mus rau theem ntawm kev yeej yuav siv tag nrho thiab qhov muaj zog yog ib txwm muaj zog.Raws li qhov tshwm sim, cov khoom siv raw khoom siv (cov lag luam loj hauv tsev thiab txawv teb chaws thiab cov chaw tsim khoom xws li cov ntaub hauv paus) tau maj mam txav mus rau hauv nruab nrab txoj cai monopoly, thiab yuav muab ntau dua tus nqi zog.Qhov xwm txheej ntawm cov khoom siv hluav taws xob sab saud 'tus nqi zog muaj zog ntxiv txwv qhov nyiaj tau los ntawm cov lag luam.PVC tawv xav tau plasticizer DOP thiab stabilizers uas muaj cov hlau hnyav xws li txhuas thiab cadmium, uas yooj yim rau paug ib puag ncig.Nws tau raug teev tseg raws li kev txwv txoj kev loj hlob nyob rau hauv Catalog rau Kev Taw Qhia ntawm Kev Txhim Kho Kev Lag Luam.Txawm li cas los xij, cov kuab tshuaj xws li polyurethane thiab DMF, uas tau siv dav hauv kev tsim cov tawv PU, yuav tsim cov organic tebchaw (VOCs), uas yuav tsum tsis txhob muaj zog.Cov qauv ntawm ntsuab thiab ib puag ncig-phooj ywg txoj kev loj hlob ntawm hluavtaws tawv hauv Suav teb tau pom tseeb heev.
