Cov tshuaj fiber ntau muaj feem cuam tshuam nrog kev nyiam roj. Ntau tshaj 90% ntawm cov khoom lag luam hauv kev lag luam chemical fiber ntau yog raws li cov khoom siv roj av, thiab cov khoom siv raw rau polyester, nylon, acrylic, polypropylene thiab lwm yam khoom hauv cov saw hlau yog tag nrho los ntawm cov roj av, thiab qhov kev thov roj av nce ntxiv. xyoo dhau xyoo. Yog li ntawd, yog tias tus nqi ntawm cov roj crude poob qis heev, cov nqi ntawm cov khoom xws li naphtha, PX, PTA, thiab lwm yam yuav ua raws li kev nplua, thiab cov nqi ntawm cov khoom polyester downstream yuav raug cuam tshuam los ntawm kev sib kis.
Raws li kev nkag siab zoo, qhov txo qis ntawm cov nqi raw khoom yuav tsum muaj txiaj ntsig zoo rau cov neeg siv khoom qis los yuav. Txawm li cas los xij, cov tuam txhab yeej ntshai yuav, vim tias nws yuav siv sijhawm ntev los ntawm kev yuav khoom ntawm cov khoom siv raw rau cov khoom, thiab cov chaw tsim khoom polyester yuav tsum tau xaj ua ntej, uas muaj cov txheej txheem lag luam piv rau cov khoom lag luam, uas ua rau cov khoom lag luam poob qis. . Nyob rau hauv cov xwm txheej zoo li no, nws nyuaj rau kev lag luam kom tau txais txiaj ntsig. Ntau qhov kev lag luam sab hauv tau nthuav tawm cov kev xav zoo sib xws: thaum cov lag luam yuav cov khoom siv raw, lawv feem ntau yuav nce ntau dua li qis. Thaum cov roj nqi poob qis, tib neeg tau ceev faj txog kev yuav khoom. Hauv qhov xwm txheej no, nws tsis tsuas yog exacerbates tus nqi poob ntawm cov khoom lag luam ntau, tab sis tseem cuam tshuam ncaj qha rau cov khoom lag luam ib txwm muaj.
Cov ntaub ntawv tseem ceeb ntawm lub khw muag khoom:
1. Kev lag luam thoob ntiaj teb cov roj crude yav tom ntej tau poob, tsis muaj zog txhawb rau PTA cov nqi.
2. Lub peev xwm ua haujlwm ntawm PTA yog 82.46%, nyob ze ntawm qhov pib siab ntawm lub xyoo, nrog cov khoom txaus txaus. PTA lub ntsiab yav tom ntej PTA2405 poob ntau dua 2%.
Kev sib sau ntawm PTA cov khoom muag hauv 2023 feem ntau yog vim qhov tseeb tias 2023 yog lub xyoo siab tshaj plaws rau PTA nthuav dav. Txawm hais tias downstream polyester tseem muaj peev xwm nthuav tawm ntau lab tons, nws nyuaj rau kev zom cov khoom nce hauv PTA. Qhov kev loj hlob ntawm PTA cov khoom lag luam hauv zej zog tau nrawm dua nyob rau ib nrab xyoo 2023, feem ntau yog vim kev tsim khoom ntawm 5 lab tons ntawm PTA tshiab muaj peev xwm los ntawm lub Tsib Hlis mus txog Lub Xya Hli. Zuag qhia tag nrho PTA cov khoom lag luam sib raug zoo nyob rau hauv ib nrab ntawm lub xyoo yog nyob rau theem siab hauv tib lub sijhawm ze li peb xyoos.
