Raws li kev txheeb cais, Tuam Tshoj cov acrylic acid ntau tshaj 2 lab tons hauv 2021, thiab cov acreblic acid yuav tshaj 40 lab tons. Cov Acrylate kev lag luam saw siv Acrylic Usters los tsim Acrylic Usters yog tsim los ntawm kev haus dej cawv. Cov neeg sawv cev ntawm Acrylates yog: Butl Acrylate, isooctyl acrylate, Methyl acrylate, Ethyl Acrylate thiab Acrylic Acid Siab Resin. Ntawm lawv, qhov ntau lawm cov nplai ntawm Butyl acrylate yog loj, nrog ntau lawm yog ntau tshaj li 1.4 lab tons hauv 2021. Qhov thib peb yog isooctyl acrylate, nrog kev tsim khoom Ntawm ntau dua 340,000 tons hauv 2021. Kev tsim cov methyl acrylate thiab ethyl acrylate yuav 78,000 tons thiab 56,000 tons nyob rau hauv 2021.

Txog kev thov hauv cov saw hlau, acrylic acid feem ntau tsim acrylic esters, thiab butyl acrylate tuaj yeem tsim raws li cov nplaum. Methyl acrylate yog siv nyob rau hauv txheej kev lag luam, cov nplaum, emulslate roj hmab thiab cov nplaum kev lag luam, uas muaj qee qhov sib tshooj ntawm methyl acrylate. Isooctyl acrylate yog siv raws li lub siab-rhiab nplaum monomer, thiab lwm yam kua ntoo yog siv raws li cov ntaub qhwv siab heev, xws li cov pawm.

Raws li cov khoom lag luam ntsig txog cov acrylate kev lag luam saw hauv ob xyoos dhau los, cov nyiaj tau muag / muag / muag khoom) kev sib piv / cov txiaj ntsig hauv qab no tuaj yeem tau txais.

1. Hauv kev lag luam acrylate actural nyob hauv Suav teb, qhov nyiaj tau los ntawm cov khoom muaj txiaj ntsig zoo tshaj plaws yog qhov siab tshaj plaws, nrog rau Naphha thiab Propylene muaj cov txiaj ntsig siab muaj txiaj ntsig. 2021 Naphhat cov nyiaj tau paj tau yog nyob ib ncig ntawm 56%, Propylene Tau txiaj ntsig yog nyob ib ncig ntawm 38%, thiab Acrylic Tau txiaj ntsig yog ib puag ncig 41%.

2. Ntawm cov khoom siv acrylate, cov nyiaj tau paj ntawm methyl acrylate yog qhov siab tshaj plaws. Qhov nyiaj tau paj ntawm Methyl acrylate nce mus txog 52% hauv 2021, ua raws li Ethyl acrylate nrog nyiaj tau los ntawm txog 30%. Qhov nyiaj tau paj ntawm Butyl Acrylate tsuas yog txog 9%, isooctyl acrylate yog nyob rau hauv SAP, thiab cov nyiaj ntawm SAP yog ib puag ncig 11%.

3. Ntawm cov kws tsim khoom acrylate, ntau dua 93% yog nruab nrog cov ntoo acrylic acid cov nroj tsuag, feem ntau ntawm cov uas muaj cov khoom lag luam loj hauv cov lag luam loj. Los ntawm cov peev txheej tam sim no ntawm Acrylate kev lag luam saw, thaum muaj acrylate cov neeg lag luam uas tsis muaj acrylic acid muaj acrylic acid tsis muaj nyiaj tsawg.

4, ntawm cov kws tsim khoom acrylate, cov nyiaj tau paj ntawm cov neeg muaj peev xwm loj heev tau muaj nyob hauv ob xyoos, nrog cov nyiaj tau los ntawm 9% -10%. Txawm li cas los xij, vim yog kev ua lag luam hloov pauv, cov nyiaj tau paj ntawm cov neeg ua haujlwm tshwj xeeb uas muaj kev hloov pauv hloov tau zoo heev. Qhov no qhia tau tias kev ua lag luam tau nyiaj ntawm cov khoom loj yog qhov ruaj khov, thaum cov khoom me me muaj kev cuam tshuam nrog cov peev txheej ntawm cov khoom siv thiab cov khoom lag luam hauv khw.

5, Los ntawm Acrylate Kev Lag Luam saw tuaj yeem pom, kev lag luam tsim cov txheej txheem acrylate, thaum muaj peev xwm txhim kho hauv kev txhawb nqa ntawm Butyyl acrylate, uas tuaj yeem txhim kho kev tiv thaiv kev ua lag luam , tab sis kuj tseem yog ib hom tsim nyog.

Rau yav tom ntej, Methyl acrylate, Ethyl Acrylate thiab Isooctyl Acrylate thiab Isooctyl Acrylate muaj lawv tus kheej cov kev lag luam hauv nroog Los ntawm kev ua lag luam thiab kev thov theem, methyl acrylate thiab ethyl acrylate muaj qhov teeb meem siab oversuply thiab yav tom ntej kev saib xyuas yog qhov nruab nrab. Tam sim no, butyl acrylate, isooctyl acrylate thiab kua ntoo tseem muaj qee cov khoom siv nrog cov khoom lag luam acrylate yav tom ntej.

Rau cov nce toj kawg ntawm acrylic acid, propylene thiab naphtha, uas maj mam nce ntxiv, yuav tau txais txiaj ntsig zoo dua li cov acrylic acid. Yog li ntawd, yog cov tuam txhab tsim cov acrylate kev lag luam saw, lawv yuav tsum them nyiaj ntau rau kev txhim kho ntawm txoj kev sib txuas ntawm kev lag luam saw, yuav muaj kev ua lag luam ua lag luam.
