Lub Yim Hli 31, Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam tau tshaj tawm" Kev tshaj tawm txog Kev Tshawb Fawb Kev Tiv Thaiv Kev Raug Tshuaj los ntawm Kev Nkag Khoom ntawm Monoalkyl Ether Cov Neeg Ua Ncaj Qha Ethylene Glycol thiab Propylene Glycol Keeb kwm hauv Tebchaws Meskas."
Qee cov ntsiab lus muaj raws li hauv qab no:
1. Kev tshawb nrhiav thiab lub sijhawm tshawb nrhiav
Txij li hnub ntawm daim ntawv tshaj tawm no, Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam tau pib ua kev tshawb fawb txog kev tiv thaiv kev khib nyiab ntawm kev ntshuam ntawm ethylene glycol thiab propylene glycol monoalkyl ethers keeb kwm hauv Tebchaws Meskas. Lub sijhawm khib nyiab uas tau txiav txim siab hauv qhov kev tshawb nrhiav no yog txij lub Ib Hlis 1, 2019 txog 2019. Lub Kaum Ob Hlis 31, lub sijhawm tshawb nrhiav txog kev puas tsuaj rau kev lag luam yog txij Lub Ib Hlis 1, 2016 txog Lub Kaum Ob Hlis 31, 2019.
2. Cov khoom lag luam nyob hauv kev tshawb nrhiav thiab qhov sib txawv ntawm kev tshawb nrhiav
Kev ntsuas ntawm kev tshawb nrhiav: txawv teb monoalkyl ethers ntawm ethylene glycol thiab propylene glycol keeb kwm nyob hauv Tebchaws Meskas.
Lub npe ntawm cov khoom lag luam hauv kev tshawb xyuas: ntsig txog monoalkyl ethers ntawm ethylene glycol thiab propylene glycol.
Cov Khoom Qhia: Cov ntsig txog monoalkyl ethers ntawm ethylene glycol thiab propylene glycol yog cov xim tsis muaj kob thiab pob tshab nrog lub ntsej muag tsis hnov tsw ether. Lawv tuaj yeem tso tsis tau nrog dej, haus dej cawv, ketones, ethers, esters, muaj ntxhiab hydrocarbons, aliphatic hydrocarbons, thiab lwm yam, thiab tuaj yeem yaj ntau hom polymer. Yam ntsig txog ethylene glycol monoalkyl ethers hais txog cawv ethers synthesized los ntawm ethylene oxide thiab cawv, nrog pawg ethoxy (cov qauv tshuaj molecular C2H4O) nyob rau hauv cov molecular saw, tseem hu ua glycol ethers lossis E-series Cawv cawv ether, tab sis tsis muaj ethylene glycol lossis diethylene glycol monobutyl ether. Yam ntsig txog propylene glycol monoalkyl ethers hais txog cawv ethers synthesized los ntawm propylene oxide thiab cawv nrog cov pab pawg propoxy (qauv cov qauv molecular C3H6O) hauv cov saw hlau. Lawv tseem hu ua propylene glycol ethers lossis P-series cawv ethers. Muaj cov tshuaj propylene glycol methyl ether.
Kev siv loj: Cov ntsig txog monoalkyl ethers ntawm ethylene glycol thiab propylene glycol feem ntau yog siv los ua cov kuab tshuaj, khoom tawg thiab kua, nrog rau roj ua rau cov tshuaj lom neeg thiab cov tshuaj rho tawm. Lawv tseem yog cov tseem ceeb organic ua raw cov ntaub ntawv. Lawv tau dav siv hauv photoresists thiab tsho tiv no. Cov paib tooj liab, cov khoom siv hluav taws xob, cov tshuaj tua hluav taws xob, cov roj av roj tiv thaiv kab mob, cov khoom siv txheej, luam ntawv inks, luam ntawv luam ntawv thiab zas xim, tshuaj thiab tshuaj tua kab, tshuaj txhua hnub thiab lwm cov teb.
Cov khoom no tau teev nyob rau hauv" Ntshuam thiab Ntsuas Nqi ntawm Cov Neeg' s koom pheej ntawm Tuam Tshoj": 29094400 thiab 29094990. Cov khoom lag luam uas tsis yog monoalkyl ethers ntawm ethylene glycol thiab propylene glycol nyob rau hauv tus nqi suav 29094990 tsis yog nyob rau hauv qhov ntsuas ntawm kev tshawb nrhiav no.
Raws li cov ntawv sau tawm tsam, cov neeg tsim khoom lag luam thiab cov xa tawm koom nrog hauv cov ntawv thov feem ntau suav nrog Dow Chemical Company, Eastman Chemical Company thiab Lyondell Basel.
3. Thov rau kev tshawb nrhiav kev ntshuam ntawm cov khoom
Thaum 2016 thiab 2019, cov naj npawb ntawm cov khoom lag luam tau thov rau kev tshawb nrhiav nce ntxiv. Nyob rau xyoo 2016, qhov ntawv ntim khoom yog 18,000 tons. Hauv 2017, nws ntau ntxiv rau 24,000 tons. Txij li thaum ntawd, nws tau tshaj 30,000 tons hauv 2018 thiab 2019. Qhov kev nce zuj zus nyob rau lub sijhawm plaub xyoos tau nce mus txog 68.59%.
