Propylene glycol methyl ether acetate waa nooc ka mid ah dareeraha horumarsan. Molekule-keedu wuxuu ka kooban yahay isku-xidhka ether iyo kooxda carbonyl, kooxda carbonyl-na waxay samaysaa qaab-dhismeedka ester-ka waxayna ka kooban tahay kooxda alkyl. Isla molekule-ka, waxaa jira qaybo aan polar ahayn iyo qaybo polar ah, kooxaha shaqeynaya ee labadan qayboodna ma aha oo kaliya inay is xaddidaan oo ay iska celiyaan, laakiin sidoo kale waxay ciyaaraan doorarkooda dabiiciga ah. Sidaa darteed, waxay leedahay milmi gaar ah oo loogu talagalay walxaha aan polar ahayn iyo kuwa polar labadaba. Propylene glycol methyl ether acetate waxaa lagu sameeyay esterification propylene glycol methyl ether iyo glacial acetic acid iyadoo la adeegsanayo aashitada sulfuric ee xoogga leh sida kataliyaha. Waa dareere warshadeed oo aad u wanaagsan oo sun yar, wuxuu leeyahay awood xooggan oo uu ku milmo walxaha polar iyo kuwa aan polar ahayn, oo ku habboon dahaarka heerka sare ah, dareere khad ah oo polymers kala duwan ah, oo ay ku jiraan aminomethyl ester, vinyl, polyester, cellulose acetate, alkyd resin, acrylic resin, epoxy resin iyo nitrocelluloses. Kuwaas waxaa ka mid ah. Propylene glycol methyl ether propionate waa dareeraha ugu fiican ee rinjiga iyo khadku ku jiro, oo ku habboon polyester aan dheregsanayn, resin polyurethane, resin acrylic, resin epoxy iyo wixii la mid ah.

Sida laga soo xigtay "Warbixinta Daraasadda Mashruuca Maalgashiga ee methyl ether acetate (PMA) ee Shiinaha 2023-2027" oo ay soo saartay Xarunta Cilmi-baarista Warshadaha Xinsijie, marxaladdan, tignoolajiyada wax soo saarka ee propanediol methyl ether acetate ee Shiinaha ayaa si tartiib tartiib ah u soo hagaagtay, waxqabadkeeda dhammaystiran ayaa si tartiib tartiib ah u soo hagaagay, goobta codsigeeda ayaa si tartiib tartiib ah u ballaaratay, waxayna si tartiib tartiib ah u kortay semiconductor, substrate photoresist, saxanka naxaasta ah iyo suuqyo kale. Baahida suuqu si tartiib tartiib ah ayay u koraysaa. Iyada oo hoos timaada asalkan, cabbirka suuqa ee propylene glycol methyl ether acetate ee Shiinaha ayaa muujinaya isbeddel sii kordhaya sannadba sannadka ka dambeeya. Laga bilaabo 2015 ilaa 2022, cabbirka suuqa ee propylene glycol methyl ether acetate ee Shiinaha ayaa ka kordhay 2.261 bilyan yuan ilaa 3.397 bilyan yuan, iyadoo heerka kobaca sanadlaha ah ee isku-dhafka ah uu yahay 5.99%. Kuwaas ka mid ah, suuqa kiimikada Tianyin ayaa ahaa saamiga ugu badan, isagoo gaaray 25.7%; Kiimikada Hualun ayaa ku xigta, oo ka dhigan 13.8% suuqa; Kaalinta saddexaad waxaa ku jirta Jida Chemical, oo leh saami suuqeed dhan 10.4%. Iyadoo si joogto ah loo horumarinayo warshadaha propylene glycol methyl ether acetate ee Shiinaha, qaab-dhismeedka awoodda ayaa si tartiib tartiib ah loo hagaajiyaa, awoodda wax soo saarka ee dib u dhaca ayaa si tartiib tartiib ah loo baabi'iyaa, waxaana la filayaa in diiradda suuqa ay sii kordho mustaqbalka.

Oktoobar 19, qiimaha propylene glycol methyl ether acetate ee gudaha wuxuu ahaa 9800 yuan/tan. Tilmaamaha propylene glycol methyl ether acetate: 200 kg/foosto 99.9% heerka qaran ee ku jira. Dalabku wuxuu shaqeynayaa 1 maalin. Bixiyaha qiimaha: Xiamen Xiangde Supreme Chemical Products Co., LTD.

Waqtigan xaadirka ah, iyadoo la horumarinayo dahaarka, khad, daabacaadda iyo rinjiyeynta, dharka iyo warshadaha kale ee Shiinaha, baahida suuqa ee warshadaha propylene glycol methyl ether acetate ee Shiinaha ayaa sii kordheysa, heerka wax soo saarka gudaha ee propylene glycol methyl ether acetate warshadaha ayaa sii kordhaya. Si kastaba ha ahaatee, tiknoolajiyada wax soo saarka ee heerka elektaroonigga ah iyo xitaa heerka semiconductor propylene glycol methyl ether acetate waa mid aad u adag. Waqtigan xaadirka ah, shirkadaha maxalliga ah ee Shiinaha ee propylene glycol methyl ether acetate waxay leeyihiin boos weyn oo suuqa soo dejinta ah oo ku yaal goobtan. Propylene glycol methyl ether heerka elektaroonigga ah iyo propylene glycol methyl ether acetate waxaa loo isticmaali karaa sidii wakiil nadiifin, nadiifin ama dareere xoqid ah si loo soo saaro qaybaha elektaroonigga ah oo ay ku jiraan semiconductors, substrates photoresist, saxanadaha naxaasta lagu dahaadhay, bandhigyada kiristaalka dareeraha ah iyo beeraha kale. Shiinaha ayaa dhawaan soo bandhigay tiro ka mid ah qorshayaasha "shan iyo toban" si loogu dhiirrigeliyo horumarinta warshadaha semiconductor-ka iyo warshadaha kale ee qalabka tiknoolajiyada sare, warshadaha propylene glycol methyl ether acetate ee Shiinaha ama waxay awoodi doonaan inay qaataan dabaysha bari ee siyaasadda, kor u qaadaan horumarinta iyo ballaarinta propylene glycol methyl ether acetate ee heerka elektaroonigga ah, iyadoo isbeddelka beddelka soo dejinta gudaha ee mustaqbalka uu kordhay, warshadaha propylene glycol methyl ether acetate ee heerka elektaroonigga ah ee Shiinaha ayaa abuuri doona meel faa'iido badan u leh warshadaha, iyadoo qiimo maalgashi oo weyn leh.
