ʻO ka propylene glycol methyl ether acetate kahi ʻano mea hoʻoheheʻe holomua. Aia i loko o kāna mole ka pilina eter a me ka pūʻulu kalapona, a ʻo ka pūʻulu carbonyl ka hana o ka ester a loaʻa ka pūʻulu alkyl. I loko o ka mole hoʻokahi, aia nā ʻāpana non-polar a me nā ʻāpana polar, a ʻo nā pūʻulu hana o kēia mau ʻāpana ʻelua ʻaʻole wale i kaohi a hoʻopaʻapaʻa kekahi i kekahi, akā ke pāʻani pū nei i kā lākou kuleana. No laila, loaʻa iā ia kahi solubility no nā mea non-polar a me polar. Ua hana ʻia ka propylene glycol methyl ether acetate e ka esterification o ka propylene glycol methyl ether a me ka ʻakika acetic glacial me ka hoʻohana ʻana i ka waikawa sulfuric concentrated ma ke ʻano he catalyst. He mea hoʻoheheʻe haʻahaʻa haʻahaʻa haʻahaʻa maikaʻi loa ia, he ikaika ikaika e hoʻopau i nā mea polar a me nā mea ʻole polar, kūpono no nā uhi kiʻekiʻe, ink solvents o nā polymers like ʻole, me ka aminomethyl ester, vinyl, polyester, cellulose acetate, alkyd resin, acrylic resin, epoxy resin a me nitrocelluloses. Iwaena o lakou. ʻO ka propylene glycol methyl ether propionate ka mea hoʻoheheʻe maikaʻi loa i ka pena a me ka inika, 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 maikaʻi ʻia ka ʻenehana hana propanediol methyl ether acetate o Kina, ua hoʻomaikaʻi maikaʻi kāna hana holoʻokoʻa, ua hoʻonui nui ʻia kāna kahua noi, a ua hoʻonui lohi ʻia kona kahua kiʻi. pāpaʻa keleawe a me nā mākeke ʻē aʻe. Ke ulu mālie nei ka makemake o ka mākeke. Ma lalo o kēia kāʻei kua, hōʻike ka mākeke mākeke o propylene glycol methyl ether acetate ma Kina i ka piʻi ʻana i kēlā me kēia makahiki. Mai 2015 a 2022, ua hoʻonui ʻia 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 nui o ka ulu ʻana o ka makahiki he 5.99%. Ma waena o lākou, ʻo Tianyin kemika mākeke i helu ʻia no ka hapa nui loa, hiki i ka 25.7%; Ua ukali ʻo Hualun Chemical, ʻo ia ka 13.8% o ka mākeke; Ma ke kolu o ka wahi ʻo Jida Chemical, me ka māhele mākeke o 10.4%. Me ka hoʻomau mau ʻana o ka ʻoihana propylene glycol methyl ether acetate o Kina, ua hoʻonui ʻia ke ʻano o ka hiki, ua hoʻopau ʻia ka mana hana hope, a ke manaʻo ʻia nei e hoʻonui hou ʻia ka mākeke i ka wā e hiki mai ana.

Ma ʻOkakopa 19, ʻo ka ʻōlelo ʻana o ka propylene glycol methyl ether acetate home he 9800 yuan / ton. Nā kikoʻī o propylene glycol methyl ether acetate: 200 kg/barela 99.9% maʻiʻo maʻamau maʻamau. Pono ka hāʻawi no 1 lā. Mea hāʻawi ʻōlelo: Xiamen Xiangde Supreme Chemical Products Co., LTD.

I kēia manawa, me ka hoʻomohala ʻana o ka uhi ʻana, ka inika, ka paʻi ʻana a me ke kala, textile a me nā ʻoihana ʻē aʻe ma Kina, ke ulu nei ka noi mākeke o ka ʻoihana propylene glycol methyl ether acetate o Kina, a ke piʻi aʻe nei ka nui o ka hana ʻana o ka propylene glycol methyl ether acetate. Eia nō naʻe, paʻakikī ka ʻenehana hana o ka papa uila a me ka semiconductor grade propylene glycol methyl ether acetate. I kēia manawa, loaʻa i nā ʻoihana kūloko o Kina o propylene glycol methyl ether acetate kahi wahi kūʻai nui o ka mākeke lawe mai i kēia kahua. Hiki ke hoʻohana ʻia ka propylene glycol methyl ether a me ka propylene glycol methyl ether acetate e like me ka diluent, ka mea hoʻomaʻemaʻe a i ʻole ka wehe ʻana i ka wai no ka hana ʻana i nā mea uila me nā semiconductors, nā substrate photoresist, nā papa keleawe-aahu, nā hōʻike aniani wai a me nā māla ʻē aʻe. Ua hoʻolauna hou ʻo Kina i kekahi mau papahana "ʻumikūmāhā ʻelima" i ʻōlelo ʻia e paipai i ka hoʻomohala ʻana i ka semiconductor a me nā ʻoihana ʻenehana kiʻekiʻe, ʻo ka propylene glycol methyl ether acetate ʻoihana Kina a i ʻole e hiki ke lawe i ka makani hikina o ke kulekele, e piʻi aʻe i ka hoʻomohala ʻana a me ka hoʻonui ʻana o ka propylene glycol methyl ether acetate, me ka hoʻonui ʻana i ka ʻoihana hoʻololi i ka hale e hiki mai ana. ka nui o ka loaʻa kālā no ka ʻoihana, me ka waiwai waiwai nui.
