Cov tshuaj formula: C6H12O3
Propylene glycol methyl ether acetate yog ib hom tshuaj hnyav heev. Nws cov molecule muaj ob qho tib si ether daim ntawv cog lus thiab carbonyl pawg, thiab pawg carbonyl tsim cov qauv ntawm ester thiab muaj cov alkyl pawg. Nyob rau hauv tib lub molecule, muaj ob qho tib si tsis-polar qhov chaw thiab polar qhov chaw, thiab cov pab pawg neeg ua hauj lwm ntawm ob qhov chaw no tsis tsuas yog txwv thiab tawm tsam ib leeg, tab sis kuj ua si lawv lub luag hauj lwm hauv paus ntsiab lus. Yog li ntawd, nws muaj qee yam solubility rau ob qho tib si tsis-polar thiab polar tshuaj. Propylene glycol methyl ether acetate tau tsim los ntawm esterification ntawm propylene glycol methyl ether thiab glacial acetic acid siv concentrated sulfuric acid ua catalyst. Nws yog ib qho zoo heev uas tsis muaj tshuaj lom neeg hnyav heev, muaj peev xwm ua kom yaj cov polar thiab tsis-polar, haum rau cov qib high-qib coatings, number case solvents ntawm ntau yam polymers, xws li aminomethyl ester, vinyl, polyester, cellulose acetate, alkyd resin. , acrylic resin, epoxy resin thiab nitrocelluloses. Ntawm lawv. Propylene glycol methyl ether propionate yog cov kuab tshuaj zoo tshaj plaws hauv cov xim thiab number case, haum rau unsaturated polyester, polyurethane resin, acrylic resin, epoxy resin thiab lwm yam.
Raws li "2023-2027 Tuam Tshoj Propanediol methyl ether acetate (PMA) Project Investment Feasibility Study Report" tso tawm los ntawm Xinsijie Industry Research Center, nyob rau theem no, Tuam Tshoj tus propanediol methyl ether acetate ntau lawm tshuab tau maj mam txhim kho, nws cov kev ua tau zoo tau maj mam txhim kho, nws daim ntawv thov teb tau maj mam nthuav dav, thiab nws tau maj mam tsim mus rau hauv semiconductor, photoresist substrate, tooj liab clad phaj thiab lwm yam lag luam. Kev lag luam xav tau nce zuj zus. Raws li keeb kwm yav dhau los no, kev ua lag luam nplai ntawm propylene glycol methyl ether acetate hauv Suav teb qhia tau tias muaj kev sib tw ntau xyoo. Los ntawm 2015 txog 2022, kev lag luam loj ntawm propylene glycol methyl ether acetate hauv Suav teb tau nce los ntawm 2.261 billion yuan mus rau 3.397 billion yuan, nrog kev loj hlob txhua xyoo ntawm 5.99%. Ntawm lawv, Tianyin tshuaj ua lag luam suav txog qhov loj tshaj plaws, nce mus txog 25.7%; Hualun Chemical ua raws, suav txog 13.8% ntawm kev ua lag luam; Hauv qhov chaw thib peb yog Jida Chemical, nrog rau kev lag luam feem ntawm 10.4%. Nrog rau kev txhim kho tas mus li ntawm Tuam Tshoj txoj kev lag luam propylene glycol methyl ether acetate kev lag luam, lub peev xwm tsim tau maj mam hloov kho, rov qab muaj peev xwm tsim tau maj mam tshem tawm, thiab nws cov kev lag luam concentration xav tias yuav nce ntxiv rau yav tom ntej.
Thaum Lub Kaum Hli 19, cov lus hais ntawm domestic propylene glycol methyl ether acetate yog 9800 yuan / ton. Specifications ntawm propylene glycol methyl ether acetate: 200 kg / chim 99.9% cov ntsiab lus teb chaws tus qauv. Qhov kev thov no siv tau rau 1 hnub. Tus neeg zov me nyuam: Xiamen Xiangde Supreme Chemical Products Co., LTD.
Tam sim no, nrog rau txoj kev loj hlob ntawm txheej, number case, luam ntawv thiab dyeing, textile thiab lwm yam lag luam nyob rau hauv Tuam Tshoj, kev lag luam kev lag luam ntawm Tuam Tshoj tus propylene glycol methyl ether acetate kev lag luam yog loj hlob, thiab domestic ntau lawm tus nqi ntawm industrial propylene glycol methyl ether acetate tau txais. siab dua thiab siab dua. Txawm li cas los xij, kev tsim cov thev naus laus zis ntawm qib hluav taws xob thiab txawm tias qib semiconductor propylene glycol methyl ether acetate yog qhov nyuaj. Tam sim no, Tuam Tshoj cov chaw lag luam hauv zos ntawm propylene glycol methyl ether acetate muaj qhov chaw hloov khoom lag luam loj dua hauv daim teb no. Electronic qib propylene glycol methyl ether thiab propylene glycol methyl ether acetate tuaj yeem siv ua diluent, tu tus neeg saib xyuas lossis stripping kua rau cov khoom siv hluav taws xob xws li semiconductors, photoresist substrates, tooj liab clad daim hlau, kua siv lead ua kua thiab lwm yam. Tuam Tshoj tsis ntev los no tau tshaj tawm ib tug xov tooj ntawm " kaum plaub tsib" txoj kev npaj tau hais los txhawb txoj kev loj hlob ntawm semiconductor thiab lwm yam khoom siv high-tech kev lag luam, Tuam Tshoj txoj kev lag luam propylene glycol methyl ether acetate los yog yuav muaj peev xwm coj cov cua sab hnub tuaj ntawm txoj cai, nce qib. txoj kev loj hlob thiab nthuav dav ntawm qib hluav taws xob propylene glycol methyl ether acetate, nrog rau yav tom ntej kev hloov pauv hloov pauv hauv tsev, Tuam Tshoj cov khoom siv hluav taws xob qib propylene glycol methyl ether acetate kev lag luam yuav tsim ntau qhov chaw tau txais txiaj ntsig rau kev lag luam, nrog rau kev nqis peev zoo.
