1. Tseem muaj qee qhov sib txawv ntawm cov khoom siv ua PVC hauv tsev thiab cov khoom txawv teb chaws, thiab tus nqi qis tsis muaj qhov zoo dua hauv kev sib tw ua lag luam.
Txawm hais tias cov khoom lag luam hauv tsev muaj qee qhov zoo ntawm thaj chaw thiab tus nqi hauv kev sib tw ua lag luam, peb muaj qee qhov sib txawv hauv kev ua tau zoo ntawm cov khoom, ntau yam, kev ruaj khov, thiab lwm yam piv rau cov khoom txawv teb chaws. Qhov no cuam tshuam nrog qhov rov qab ntawm peb cov mis khoom, kev siv tshuab ua, kev ua tiav, thiab kev siv tshuab tom qab kho. Qee lub tuam txhab lag luam hauv tsev paub txog cov teeb meem no thiab tau tsim kev sib raug zoo nrog cov koom haum tshawb fawb, cov koom haum tshawb fawb thiab kev txhim kho, thiab ua kev tshawb fawb txog cov khoom siv yas ntxiv.
2. Cov chaw tsim khoom me me muaj ntau haiv neeg thiab tsis muaj lub tuam txhab ua lag luam uas muaj txoj haujlwm tiav, ua rau muaj kev sib tw tsis sib haum xeeb hauv kev ua lag luam.
Tam sim no, muaj li ntawm 30 lub tuam txhab tsim khoom ACR hauv tebchaws, tab sis tsuas yog 4 ntawm lawv muaj kev tsim khoom loj (nrog rau lub peev xwm teeb tsa txhua xyoo ntawm ntau dua 5000 tons). Cov khoom lag luam ntawm cov lag luam loj no tau tsim kom muaj lub koob npe zoo hauv kev lag luam hauv tebchaws thiab thoob ntiaj teb, tsis hais txog ntau yam khoom thiab zoo. Tab sis ob xyoos dhau los, nrog kev vam meej ntawm kev lag luam ua PVC, qee lub Hoobkas me me ACR nrog lub peev xwm tsim khoom tsawg dua 1000 tons tau maj mam mus rau kev ua lag luam. Vim lawv cov khoom siv yooj yim thiab kev ruaj khov khoom tsis zoo, cov lag luam no tsuas yog muaj sia nyob los ntawm kev siv cov khoom pov tseg pheej yig, ua rau muaj kev sib tw nqi hnyav hauv kev ua lag luam hauv tebchaws. Qee cov khoom tsis zoo thiab qis tus qauv tam sim ntawd tau nyab lub khw, coj cov teebmeem tsis zoo rau cov lag luam ua tiav thiab tseem coj cov teebmeem tsis zoo rau kev txhim kho kev lag luam. Nws raug pom zoo tias Lub Koom Haum Ua Khoom Siv Yas ua tus thawj coj hauv kev tsim kom muaj ACR Additive Industry Association, koom ua ke cov qauv kev lag luam, tswj kev txhim kho kev lag luam, tshem tawm cov khoom cuav thiab cov khoom tsis zoo, thiab txo kev sib tw tsis sib haum xeeb. Tib lub sijhawm, cov lag luam loj yuav tsum nce lawv cov kev siv zog tsim khoom, kho lawv cov qauv khoom, thiab tswj kev txhim kho sib xws nrog cov khoom txawv teb chaws zoo sib xws.
3. Qhov nce ntawm tus nqi roj av tau ua rau tus nqi khoom siv raw nce ntxiv thiab cov nyiaj tau los ntawm cov tuam txhab txo qis.
Vim yog tus nqi roj av thoob ntiaj teb nce ntxiv tas li, txhua yam khoom siv tseem ceeb rau kev tsim ACR, methyl methacrylate thiab acrylic ester, tau nce siab heev. Txawm li cas los xij, cov neeg siv khoom hauv qab tau poob qis hauv kev nce nqi khoom, ua rau cov txiaj ntsig ntawm ACR cov lag luam poob qis. Qhov no ua rau muaj kev poob rau tag nrho kev lag luam hauv xyoo 2003 thiab 2004. Tam sim no, vim yog tus nqi khoom siv raw ruaj khov, kev lag luam tau qhia txog kev ua tau zoo.
4. Tsis muaj cov txuj ci tshaj lij, kev tshawb fawb txog kev lag luam tsis tau txhim kho tob
Vim tias ACR additive yog ib yam khoom siv polymer uas tsuas yog tsim nyob rau hauv Suav teb thaum xyoo 1990s, nws cov chaw tshawb fawb thiab kev txhim kho thiab cov kws tshawb fawb muaj tsawg dua piv rau lwm yam khoom siv xws li plasticizers thiab flame retardants hauv Suav teb. Txawm tias muaj cov tsev kawm ntawv tshawb fawb tsim nws, qhov tsis muaj kev sib koom ua ke zoo ntawm cov kws tshawb fawb thiab kev lag luam yas ua rau tsis muaj peev xwm tshawb fawb txog cov khoom. Tam sim no, kev txhim kho ACR hauv Suav teb tsuas yog vam khom cov tsev kawm ntawv tshawb fawb uas muaj ob peb lub tuam txhab los npaj thiab txhim kho. Txawm hais tias muaj qee qhov kev ua tiav tau ua tiav, muaj qhov sib txawv loj ntawm cov neeg sib tw hauv tsev thiab txawv teb chaws hauv kev nyiaj txiag tshawb fawb, cov khoom siv tshawb fawb thiab kev txhim kho, thiab kev tshawb fawb thiab kev txhim kho zoo. Yog tias qhov xwm txheej no tsis tau txhim kho zoo, nws yuav tsis paub meej tias cov khoom siv ua haujlwm puas tuaj yeem sawv ruaj khov hauv kev lag luam hauv tsev yav tom ntej.
