Propylene glycol methyl ether acetate ndi mtundu wa zosungunulira zapamwamba. Molekyu yake ili ndi ether bond ndi carbonyl group, ndipo gulu la carbonyl limapanga kapangidwe ka ester ndipo lili ndi alkyl group. Mu molekyulu yomweyo, muli zigawo zosakhala polar ndi zigawo za polar, ndipo magulu ogwira ntchito a zigawo ziwirizi samangoletsana ndi kuthamangitsana, komanso amachita ntchito zawo. Chifukwa chake, ili ndi kusungunuka kwina kwa zinthu zosakhala polar ndi polar. Propylene glycol methyl ether acetate idapangidwa mwa kuyeretsa propylene glycol methyl ether ndi glacial acetic acid pogwiritsa ntchito concentrated sulfuric acid ngati catalyst. Ndi zosungunulira zabwino kwambiri zotsika poizoni zamakampani, zili ndi mphamvu yayikulu yosungunulira zinthu zosakhala polar ndi zosakhala polar, zoyenera zokutira zapamwamba, zosungunulira inki za ma polima osiyanasiyana, kuphatikiza aminomethyl ester, vinyl, polyester, cellulose acetate, alkyd resin, acrylic resin, epoxy resin ndi nitrocelluloses. Pakati pawo. Propylene glycol methyl ether propionate ndiye chosungunulira chabwino kwambiri mu utoto ndi inki, choyenera polyester yosakhuta, polyurethane resin, acrylic resin, epoxy resin ndi zina zotero.

Malinga ndi "2023-2027 China Propanediol methyl ether acetate (PMA) Project Feasibility Study Report" yotulutsidwa ndi Xinsijie Industry Research Center, pakadali pano, ukadaulo wopanga propanediol methyl ether acetate ku China wakula pang'onopang'ono, magwiridwe ake onse akwera pang'onopang'ono, malo ake ogwiritsira ntchito akukula pang'onopang'ono, ndipo pang'onopang'ono wakula kukhala semiconductor, photoresist substrate, copper clad plate ndi misika ina. Kufunika kwa msika kukukula pang'onopang'ono. Pansi pa izi, kukula kwa msika wa propylene glycol methyl ether acetate ku China kukuwonetsa kukula chaka ndi chaka. Kuyambira 2015 mpaka 2022, kukula kwa msika wa propylene glycol methyl ether acetate ku China kudakwera kuchoka pa 2.261 biliyoni yuan kufika pa 3.397 biliyoni yuan, ndi kuchuluka kwa pachaka kwa 5.99%. Pakati pawo, msika wa mankhwala wa Tianyin udachita gawo lalikulu kwambiri, kufika pa 25.7%; Hualun Chemical idatsatira, yomwe idapanga 13.8% ya msika; Pa malo achitatu pali Jida Chemical, yomwe ili ndi gawo la msika la 10.4%. Chifukwa cha kupita patsogolo kosalekeza kwa makampani opanga propylene glycol methyl ether acetate ku China, kapangidwe ka mphamvu kakukwera pang'onopang'ono, mphamvu yopangira zinthu ikuchepa pang'onopang'ono, ndipo kuchuluka kwa zinthu zomwe zili pamsika kukuyembekezeka kuwonjezeka mtsogolo.

Pa Okutobala 19, mtengo wa propylene glycol methyl ether acetate wapakhomo unali 9800 yuan/tani. Mafotokozedwe a propylene glycol methyl ether acetate: 200 kg/mgolo 99.9% mulingo wadziko lonse. Choperekachi ndi chovomerezeka kwa tsiku limodzi. Wopereka mtengo: Xiamen Xiangde Supreme Chemical Products Co., LTD.

Pakadali pano, chifukwa cha chitukuko cha zokutira, inki, kusindikiza ndi kupaka utoto, nsalu ndi mafakitale ena ku China, kufunikira kwa msika wa propylene glycol methyl ether acetate ku China kukukulirakulira, ndipo kuchuluka kwa kupanga kwa mafakitale a propylene glycol methyl ether acetate m'nyumba kukukwera kwambiri. Komabe, ukadaulo wopanga wa propylene glycol methyl ether acetate yamagetsi komanso ngakhale ya semiconductor grade ndi wovuta kwambiri. Pakadali pano, mabizinesi aku China akumaloko a propylene glycol methyl ether acetate ali ndi malo akuluakulu osinthira msika m'munda uno. Propylene glycol methyl ether yamagetsi yamagetsi ndi propylene glycol methyl ether acetate ingagwiritsidwe ntchito ngati chosungunula, chotsukira kapena chochotsa madzi popanga zida zamagetsi kuphatikiza ma semiconductor, ma substrates a photoresist, mbale zophimbidwa ndi mkuwa, ziwonetsero zamakristalo amadzimadzi ndi madera ena. Posachedwapa China yakhazikitsa mapulani angapo a "khumi ndi anayi ndi asanu" omwe akutchulidwa kuti alimbikitse chitukuko cha mafakitale a semiconductor ndi mafakitale ena apamwamba aukadaulo, makampani aku China a propylene glycol methyl ether acetate kapena adzatha kutenga mphepo yakum'mawa ya mfundoyi, kupititsa patsogolo chitukuko ndi kukulitsa kwa propylene glycol methyl ether acetate yamagetsi, ndi tsogolo la kusintha kwa zinthu zakunja kwa dziko lapansi likuwonjezeka, makampani aku China a propylene glycol methyl ether acetate yamagetsi adzapanga malo ambiri opindulitsa kwa makampaniwa, ndi phindu lalikulu la ndalama.
