Thaum nkag mus rau lub Kaum Ob Hlis, kev lag luam acrylic acid thiab ester hauv tebchaws tau txuas ntxiv mus rau sab saud tom qab kev hloov kho luv luv. Ntawm lawv, tus nqi butyl acrylate thiab isooctyl acrylate tau nce siab heev, feem ntau yog vim cov khoom siv raw butanol nce siab dua li qhov xav tau, cov tuam txhab tsim butyl acrylate thiab isooctyl acrylate tau nce tus nqi, kev ua lag luam tau nce siab heev, kev xa khoom pheej yig hauv kev ua lag luam tau zoo dua, thiab kev muab khoom tau nce siab. Txij li hnub Wednesday, tus nqi ua lag luam butyl acrylate sab hnub tuaj ntawm Tuam Tshoj yog 9400-9500 yuan / ton, kev xa khoom tau nce 500 yuan / ton txij li thaum kawg ntawm lub hlis tas los. Tus nqi ntawm isoctyl acrylate yog 13300-13500 yuan / ton, txog li 1000 yuan / ton txij li thaum kawg ntawm lub hlis tas los.

Los ntawm qhov kev xav ntawm lwm cov khoom lag luam hauv kev lag luam, tus nqi ntawm acrylic acid tsis tshua muaj, vim tias, ntawm ib sab tes, kev ua lag luam propylene raw khoom nrog rau kev txo qis ntawm kev ntxhov siab ntawm kev muab khoom, superimposed qhov cuam tshuam ntawm kev poob qis ntawm cov roj nyoos, tus nqi ua lag luam tau poob qis tsis ntev los no. Tsis tas li ntawd, acrylic downstream dej reducer, kua txiv thiab lwm yam kev lag luam kev thov kev ua tau zoo tsis muaj zog, tsim ntawm kev rub ntawm kev ua lag luam. Tam sim no, tus nqi ntawm kev ua lag luam acrylic acid hauv sab qaum teb yog qhov ruaj khov, thiab cov kev muab ntawm qee lub tuam txhab tseem ceeb hauv kev ua lag luam Sab Hnub Tuaj thiab Sab Qab Teb Tuam Tshoj tau nce me ntsis, tab sis kev lag luam kev lag luam tseem qeeb rau kev ua raws.

Tsis tas li ntawd xwb, qhov sib txawv ntawm kev ua lag luam ntawm methyl acrylate thiab ethyl acrylate kuj ruaj khov, vim tias tag nrho cov ntim ntawm kev ua lag luam tsis loj, thiab qhov kev thov qis qis ntawm lub caij nyoog tsis tshua muaj, qhov kev hloov pauv ntawm kev ua lag luam tsis tshua muaj, tab sis los ntawm kev cuam tshuam ntawm butyl acrylate thiab lwm yam khoom, cov nqi ua lag luam tsis ntev los no kuj muaj zog.

Los ntawm qhov kev xav ntawm cov nyiaj tau los ntawm kev lag luam tam sim no, acrylic acid thiab butyl acrylate tseem poob qis, txawm hais tias tus nqi butyl acrylate nce siab lub lim tiam no, tab sis vim muaj kev nce ntxiv ntawm cov khoom siv raw, kev poob ntawm butyl acrylate tau nce ntxiv txij li thaum kawg ntawm lub hli tas los, kev xav txog tus nqi ntawm lub Hoobkas tseem nyob ntawd. Yog li ntawd, txawm hais tias tus nqi lag luam qeeb, tab sis kev muab khoom lag luam tsis ntau, thiab muaj kev txhawb nqa ntawm cov yam ntxwv nqi, kev lag luam butyl acrylate luv luv lossis tseem ua haujlwm zoo.

Zuag qhia tag nrho, kev nce qib ntawm kev lag luam acrylic thiab ester tam sim no feem ntau cuam tshuam los ntawm kev nce ntxiv ntawm cov khoom siv raw, thiab qhov kev thov tsis tu ncua ntawm lub caij tsis tseem ceeb rau kev txhawb nqa kev lag luam, nrog rau qhov kawg ntawm theem downstream ntawm kev rov ua dua tshiab, cov neeg koom nrog kev lag luam tseem txhawj xeeb txog kev lag luam yav tom ntej. Nws xav tias kev lag luam acrylic acid thiab ester yuav txuas ntxiv ua raws li kev hloov pauv ntawm cov khoom siv raw yav tom ntej.
