ʻO ka propylene glycol methyl ether acetate kahi ʻano solvent holomua. Loaʻa i kona molekala ka pilina ether a me ka hui carbonyl, a ʻo ka hui carbonyl ke ʻano o ka ester a loaʻa ka hui alkyl. Ma ka molekala hoʻokahi, aia nā ʻāpana non-polar a me nā ʻāpana polar, a ʻo nā hui hana o kēia mau ʻāpana ʻelua ʻaʻole wale e kaupalena a hoʻokuke kekahi i kekahi, akā e pāʻani pū i kā lākou kuleana kūlohelohe. No laila, he solubility kekahi no nā mea non-polar a me polar. Ua synthesized ʻia ka propylene glycol methyl ether acetate e ka esterification o ka propylene glycol methyl ether a me ka glacial acetic acid me ka hoʻohana ʻana i ka sulfuric acid i hoʻopaʻa ʻia ma ke ʻano he catalyst. He solvent ʻoihana holomua haʻahaʻa-ʻawaʻawa maikaʻi loa ia, loaʻa iā ia ka hiki ke hoʻoheheʻe i nā mea polar a me nā mea non-polar, kūpono no nā uhi kiʻekiʻe, nā solvents inika o nā polymers like ʻole, me ka aminomethyl ester, vinyl, polyester, cellulose acetate, alkyd resin, acrylic resin, epoxy resin a me nitrocelluloses. I waena o lākou. ʻO ka propylene glycol methyl ether propionate ka mea hoʻoheheʻe maikaʻi loa i ka pena a me ka ʻīnika, kūpono no ka polyester unsaturated, polyurethane resin, acrylic resin, epoxy resin a pēlā aku.

Wahi a ka "2023-2027 China Propanediol methyl ether acetate (PMA) Project Investment Feasibility Study Report" i hoʻokuʻu ʻia e Xinsijie Industry Research Center, i kēia manawa, ua hoʻomaikaʻi mālie ʻia ka ʻenehana hana propanediol methyl ether acetate o Kina, ua hoʻomaikaʻi mālie ʻia kāna hana piha, ua hoʻonui mālie ʻia kāna kahua noi, a ua ulu mālie i semiconductor, photoresist substrate, keleawe clad plate a me nā mākeke ʻē aʻe. Ke ulu mālie nei ke koi mākeke. Ma lalo o kēia ʻike, hōʻike ka nui o ka mākeke o propylene glycol methyl ether acetate ma Kina i kahi ʻano e piʻi nei i kēlā me kēia makahiki. Mai 2015 a 2022, ua piʻi ka nui o ka mākeke o propylene glycol methyl ether acetate ma Kina mai 2.261 biliona yuan a i 3.397 biliona yuan, me ka ulu makahiki hui o 5.99%. I waena o lākou, ʻo ka mākeke kemika Tianyin ka hapa nui loa, e hōʻea ana i ka 25.7%; Ua ukali ʻia ʻo Hualun Chemical, e helu ana no 13.8% o ka mākeke; Ma ke kolu o kahi ʻo Jida Chemical, me ka māhele mākeke o 10.4%. Me ka hoʻomohala mau ʻana o ka ʻoihana propylene glycol methyl ether acetate o Kina, ua hoʻomaikaʻi mālie ʻia ke ʻano o ka mana, ua hoʻopau mālie ʻia ka mana hana hope, a ke manaʻo ʻia nei e hoʻonui hou ʻia kona ʻano mākeke i ka wā e hiki mai ana.

Ma ʻOkakopa 19, ʻo ke kumukūʻai o ka propylene glycol methyl ether acetate kūloko he 9800 yuan/ton. ʻO nā kikoʻī o ka propylene glycol methyl ether acetate: 200 kg/barela 99.9% ka nui o ke kūlana aupuni. Loaʻa ka hāʻawi no 1 lā. Mea hoʻolako ʻōlelo: Xiamen Xiangde Supreme Chemical Products Co., LTD.

I kēia manawa, me ka hoʻomohala ʻana o ka uhi ʻana, ka ʻīnika, ka paʻi ʻana a me ka hoʻoluʻu ʻana, ka lole a me nā ʻoihana ʻē aʻe ma Kina, ke ulu nei ke koi mākeke o ka ʻoihana propylene glycol methyl ether acetate o Kina, a ke piʻi nei ka nui o ka hana kūloko o ka propylene glycol methyl ether acetate ʻoihana. Eia nō naʻe, he paʻakikī ka ʻenehana hana o ka papa uila a me ka papa semiconductor propylene glycol methyl ether acetate. I kēia manawa, ʻoi aku ka nui o ka mākeke hoʻololi o nā ʻoihana kūloko o Kina o ka propylene glycol methyl ether acetate ma kēia kahua. Hiki ke hoʻohana ʻia ka propylene glycol methyl ether a me ka propylene glycol methyl ether acetate ma ke ʻano he mea hoʻoheheʻe, mea hoʻomaʻemaʻe a i ʻole ka wai hoʻohemo no ka hana ʻana i nā ʻāpana uila e like me nā semiconductors, nā substrates photoresist, nā papa keleawe-clad, nā hōʻike kristal wai a me nā kahua ʻē aʻe. Ua hoʻolauna koke aku nei ʻo Kina i kekahi mau hoʻolālā "ʻumikumamāhā ʻelima" i ʻōlelo ʻia e paipai i ka hoʻomohala ʻana o ka semiconductor a me nā ʻoihana mea ʻenehana kiʻekiʻe ʻē aʻe, ʻo ka ʻoihana propylene glycol methyl ether acetate o Kina a i ʻole e hiki ke lawe i ka makani hikina o ke kulekele, e hoʻonui i ka hoʻomohala ʻana a me ka hoʻonui ʻana o ka propylene glycol methyl ether acetate papa uila, me ka hoʻonui ʻia ʻana o ke ʻano hoʻololi lawe mai kūloko i ka wā e hiki mai ana, e hoʻokumu ka ʻoihana propylene glycol methyl ether acetate papa uila o Kina i kahi nui o ka loaʻa kālā no ka ʻoihana, me ka waiwai hoʻopukapuka kālā nui.
