Propylene glycol methyl ether acetate yog ib hom tshuaj yaj uas zoo heev. Nws lub molecule muaj ob qho tib si ether bond thiab carbonyl pawg, thiab carbonyl pawg tsim cov qauv ntawm ester thiab muaj alkyl pawg. Hauv tib lub molecule, muaj ob qho tib si tsis yog polar thiab polar, thiab cov pab pawg ua haujlwm ntawm ob qho no tsis tsuas yog txwv thiab thawb ib leeg xwb, tab sis kuj ua lawv lub luag haujlwm tseem ceeb. Yog li ntawd, nws muaj qee qhov solubility rau ob qho tib si tsis yog polar thiab polar tshuaj. Propylene glycol methyl ether acetate tau synthesized los ntawm esterification ntawm propylene glycol methyl ether thiab glacial acetic acid siv concentrated sulfuric acid ua catalyst. Nws yog ib qho tshuaj yaj zoo heev uas tsis muaj tshuaj lom, muaj peev xwm yaj cov tshuaj polar thiab tsis yog polar, tsim nyog rau cov txheej txheem siab, cov tshuaj kua ntawm ntau yam polymers, suav nrog 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 pleev xim thiab kua mem, tsim rau cov polyester tsis muaj roj, 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" uas tau tso tawm los ntawm Xinsijie Industry Research Center, nyob rau theem no, Tuam Tshoj txoj kev tsim khoom propanediol methyl ether acetate tau maj mam zoo dua, nws cov kev ua tau zoo tau maj mam zoo dua, nws daim ntawv thov tau maj mam nthuav dav, thiab nws tau maj mam tsim mus rau hauv semiconductor, photoresist substrate, tooj liab clad phaj thiab lwm yam kev lag luam. Kev thov ua lag luam tab tom loj hlob maj mam. Hauv qab keeb kwm yav dhau los no, qhov loj ntawm kev ua lag luam ntawm propylene glycol methyl ether acetate hauv Suav teb qhia txog kev nce ntxiv txhua xyoo. Txij xyoo 2015 txog 2022, qhov loj ntawm kev ua lag luam ntawm propylene glycol methyl ether acetate hauv Suav teb tau nce los ntawm 2.261 billion yuan mus rau 3.397 billion yuan, nrog rau kev loj hlob txhua xyoo ntawm 5.99%. Ntawm lawv, Tianyin tshuaj lag luam suav nrog qhov feem pua ​​​​​​ntau tshaj plaws, ncav cuag 25.7%; Hualun Chemical ua raws, suav txog 13.8% ntawm kev ua lag luam; Nyob rau hauv qhov chaw thib peb yog Jida Chemical, nrog rau feem ntawm kev ua lag luam ntawm 10.4%. Nrog rau kev txhim kho tas mus li ntawm Tuam Tshoj txoj kev lag luam propylene glycol methyl ether acetate, cov qauv peev xwm maj mam txhim kho, lub peev xwm tsim khoom rov qab maj mam raug tshem tawm, thiab nws cov kev lag luam concentration yuav tsum nce ntxiv yav tom ntej.

Thaum Lub Kaum Hli 19, tus nqi ntawm cov tshuaj propylene glycol methyl ether acetate hauv tebchaws yog 9800 yuan / ton. Cov lus qhia ntawm propylene glycol methyl ether acetate: 200 kg / thoob 99.9% cov ntsiab lus tus qauv hauv tebchaws. Qhov kev thov no siv tau rau 1 hnub. Tus neeg muab kev thov: Xiamen Xiangde Supreme Chemical Products Co., LTD.

Tam sim no, nrog rau kev txhim kho ntawm kev txheej, kua mem, luam ntawv thiab zas xim, textile thiab lwm yam lag luam hauv Suav teb, qhov kev thov ua lag luam ntawm Tuam Tshoj txoj kev lag luam propylene glycol methyl ether acetate tab tom loj hlob, thiab tus nqi tsim khoom hauv tsev ntawm kev lag luam propylene glycol methyl ether acetate tau nce siab dua thiab siab dua. Txawm li cas los xij, cov thev naus laus zis tsim khoom ntawm qib hluav taws xob thiab txawm tias qib semiconductor propylene glycol methyl ether acetate kuj nyuaj heev. Tam sim no, Tuam Tshoj cov tuam txhab hauv zos ntawm propylene glycol methyl ether acetate muaj qhov chaw hloov pauv loj dua hauv daim teb no. Qib hluav taws xob propylene glycol methyl ether thiab propylene glycol methyl ether acetate tuaj yeem siv ua diluent, tus neeg sawv cev ntxuav lossis kua stripping rau kev tsim cov khoom siv hluav taws xob suav nrog semiconductors, photoresist substrates, tooj liab-clad phaj, kua siv lead ua kua thiab lwm yam teb. Tuam Tshoj nyuam qhuav qhia txog ntau txoj kev npaj "kaum plaub tsib" uas tau hais los txhawb kev txhim kho ntawm semiconductor thiab lwm yam khoom siv thev naus laus zis siab, Tuam Tshoj txoj kev lag luam propylene glycol methyl ether acetate lossis yuav muaj peev xwm coj txoj cai sab hnub tuaj, nce qib kev txhim kho thiab kev nthuav dav ntawm cov khoom siv hluav taws xob propylene glycol methyl ether acetate, nrog rau yav tom ntej kev hloov pauv hauv tsev nce ntxiv, Tuam Tshoj txoj kev lag luam hluav taws xob propylene glycol methyl ether acetate yuav tsim ntau qhov chaw muaj txiaj ntsig rau kev lag luam, nrog rau tus nqi peev txheej zoo.
