Raws li kev txheeb cais, Tuam Tshoj tus acrylic acid ntau lawm yuav ntau tshaj 2 lab tons hauv 2021, thiab acrylic acid ntau lawm yuav ntau tshaj 40 lab tons. Kev lag luam acrylate saw siv acrylic esters los tsim acrylic esters, thiab tom qab ntawd acrylic esters yog tsim los ntawm cov cawv muaj feem xyuam. Cov khoom sawv cev ntawm acrylates yog: butyl acrylate, isooctyl acrylate, methyl acrylate, ethyl acrylate thiab acrylic acid siab absorbency resin. Ntawm lawv, qhov ntau lawm ntawm butyl acrylate yog loj, nrog domestic zus tau tej cov butyl acrylate ntau tshaj 1.7 lab tons nyob rau hauv 2021. Qhov thib ob yog SAP, ntau lawm ntau tshaj 1.4 lab tons hauv 2021. Qhov thib peb yog isooctyl acrylate, nrog ib tug ntau lawm. ntawm ntau tshaj 340,000 tons hauv 2021. kev tsim cov methyl acrylate thiab ethyl acrylate yuav yog 78,000 tons thiab 56,000 tons nyob rau hauv 2021.

Rau cov ntawv thov hauv kev lag luam saw, acrylic acid feem ntau tsim cov acrylic esters, thiab butyl acrylate tuaj yeem tsim ua cov nplaum. Methyl acrylate yog siv rau hauv kev lag luam txheej, nplaum, textile emulsions, thiab lwm yam. Ethyl acrylate yog siv los ua acrylate roj hmab thiab nplaum kev lag luam, uas muaj qee qhov sib tshooj nrog kev siv methyl acrylate. Isooctyl acrylate yog siv los ua lub siab-rhiab nplaum nplaum monomer, txheej nplaum, thiab lwm yam. SAP feem ntau yog siv los ua cov khoom nqus dej ntau, xws li cov pawm.

Raws li cov khoom muaj feem xyuam hauv kev lag luam acrylate saw hauv ob xyoos dhau los, tag nrho cov nyiaj tau los sib piv (muag nyiaj tau los / muag tus nqi) sib piv, cov txiaj ntsig hauv qab no tuaj yeem tau txais.

1. nyob rau hauv kev lag luam acrylate saw nyob rau hauv Tuam Tshoj, cov nyiaj tau los ntawm cov khoom siv raw khoom kawg yog siab tshaj, nrog naphtha thiab propylene muaj cov txiaj ntsig zoo heev. 2021 naphtha cov nyiaj paj tau paj yog nyob ib ncig ntawm 56%, propylene cov paj tau paj yog nyob ib ncig ntawm 38%, thiab acrylic cov paj tau paj yog nyob ib ncig ntawm 41%.

2. Ntawm cov khoom acrylate, cov nyiaj tau los ntawm methyl acrylate yog qhov siab tshaj plaws. Cov nyiaj tau los ntawm methyl acrylate nce txog 52% hauv 2021, tom qab ntawd ethyl acrylate nrog cov txiaj ntsig ntawm kwv yees li 30%. Cov nyiaj tau los ntawm butyl acrylate tsuas yog kwv yees li 9%, isooctyl acrylate poob, thiab cov txiaj ntsig ntawm SAP yog nyob ib ncig ntawm 11%.

3. Ntawm cov neeg tsim khoom acrylate, ntau dua 93% tau nruab nrog cov nroj tsuag acrylic acid, thaum qee qhov muaj cov nroj tsuag acrylic acid, feem ntau yog cov concentrated hauv cov lag luam loj. Los ntawm cov txiaj ntsig tam sim no ntawm kev lag luam acrylate saw tuaj yeem pom, cov neeg tsim khoom acrylate nruab nrog acrylic acid tuaj yeem ua kom cov txiaj ntsig siab tshaj plaws ntawm acrylate kev lag luam saw, thaum cov neeg tsim khoom acrylate tsis muaj acrylic acid nruab nrog acrylic acid yog tsawg yig.

4, ntawm cov neeg tsim khoom acrylate, cov nyiaj tau los ntawm cov loj butyl acrylate tau tuav ib qho kev ruaj khov nyob rau hauv ob xyoos dhau los, nrog cov nyiaj tau los ntawm 9% -10%. Txawm li cas los xij, vim kev lag luam hloov pauv, cov nyiaj tau los ntawm cov neeg tsim khoom tshwj xeeb acrylic ester fluctuate heev. Qhov no qhia tau hais tias kev lag luam cov nyiaj tau los ntawm cov khoom loj yog qhov ruaj khov, thaum cov khoom me me muaj kev cuam tshuam ntau dua rau kev cuam tshuam ntawm cov peev txheej txawv teb chaws thiab kev lag luam khoom lag luam-kev xav tau tsis txaus.

5, los ntawm kev lag luam acrylate saw tuaj yeem pom, cov tuam txhab tsim cov acrylate kev lag luam saw, loj-scale ntau lawm kev taw qhia rau butyl acrylate, thaum tshwj xeeb acrylate thiab SAP yog tsim nyob rau hauv lub txhawb hom ntawm butyl acrylate, uas yuav txhim khu kev tiv thaiv ntawm lub lag luam. , tab sis kuj yog ib qho tsim nyog ntau lawm hom.

Rau yav tom ntej, methyl acrylate, ethyl acrylate thiab isooctyl acrylate muaj lawv tus kheej cov ntaub ntawv downstream nyob rau hauv cov kev lag luam acrylate saw, thiab downstream noj qhia tau hais tias kev loj hlob zoo. Los ntawm cov khoom lag luam thiab qib kev thov, methyl acrylate thiab ethyl acrylate muaj teeb meem ntau dhau thiab qhov kev pom yav tom ntej yog qhov nruab nrab. Tam sim no, butyl acrylate, isooctyl acrylate thiab SAP tseem muaj qee qhov chaw rau kev txhim kho thiab tseem yog cov khoom lag luam uas muaj txiaj ntsig zoo hauv cov khoom acrylate yav tom ntej.

Rau qhov kawg ntawm acrylic acid, propylene thiab naphtha, uas cov ntaub ntawv raw cov ntaub ntawv yog maj mam nce, cov profitability ntawm naphtha thiab propylene yuav tsum siab tshaj li ntawm acrylic acid. Yog li ntawd, yog tias cov tuam txhab tsim cov acrylate kev lag luam saw, lawv yuav tsum tau them sai sai rau kev koom ua ke ntawm kev lag luam saw thiab cia siab rau txoj kev loj hlob zoo ntawm kev lag luam saw, yuav muaj kev ua lag luam.
