propylene glycol methyl ether acetate
CAS: 84540-57-8; 108-65-6
Tātai matū: C6H12O3
Ko te propylene glycol methyl ether acetate he momo whakarewa matatau. Kei roto i tōna ngota te here ether me te rōpū carbonyl, ā, ko te rōpū carbonyl te hanganga o te ester, ā, kei roto te rōpū alkyl. I roto i te ngota kotahi, kei reira ngā wāhanga kore-poro me ngā wāhanga poro, ā, ko ngā rōpū mahi o ēnei wāhanga e rua ehara i te mea ka herea, ka panaia hoki tetahi ki tetahi, engari ka mahi anō hoki i ā rātou mahi ā-roto. Nō reira, he wairewa motuhake mō ngā matū kore-poro me ngā matū poro. I hangaia te propylene glycol methyl ether acetate mā te esterification o te propylene glycol methyl ether me te waikawa acetic glacial mā te whakamahi i te waikawa whanariki kukū hei whakakorikori. He whakarewa ahumahi matatau iti-paitini pai rawa atu, he kaha ki te whakarewa i ngā matū poro me ngā matū kore-poro, he pai mō ngā paninga kounga teitei, ngā whakarewa waituhi o ngā momo polymers, tae atu ki te aminomethyl ester, te vinyl, te polyester, te cellulose acetate, te alkyd resin, te acrylic resin, te epoxy resin me ngā nitrocelluloses. I roto i ēnei. Ko te propylene glycol methyl ether propionate te whakarewa pai rawa atu i roto i te peita me te mangumangu, he mea tika mō te polyester kore mākū, te kapia polyurethane, te kapia kiriaku, te kapia epoxy me ētahi atu.

E ai ki te "2023-2027 China Propanediol methyl ether acetate (PMA) Project Investment Feasibility Study Report" i tukuna e te Xinsijie Industry Research Center, i tēnei wā, kua piki haere te hangarau whakaputa propanediol methyl ether acetate o Haina, kua piki haere te mahi whānui, kua whānui haere te mara tono, ā, kua whanake haere ki roto i ngā mākete semiconductor, te papa photoresist, te pereti parahi me ētahi atu. Kei te piki haere te tono mākete. I raro i tēnei papamuri, kei te whakaatu te tauine mākete o te propylene glycol methyl ether acetate i Haina i tētahi au piki haere i ia tau. Mai i te tau 2015 ki te 2022, kua piki ake te rahi o te mākete o te propylene glycol methyl ether acetate i Haina mai i te 2.261 piriona yuan ki te 3.397 piriona yuan, me te tere tipu ā-tau o te 5.99%. I roto i a rātou, ko te mākete matū Tianyin te ōwehenga nui rawa atu, tae atu ki te 25.7%; i whai mai ko Hualun Chemical, ko te 13.8% o te mākete; Kei te tuatoru o ngā tūranga ko Jida Chemical, me te 10.4% te wāhanga mākete. Nā te whanaketanga tonu o te umanga propylene glycol methyl ether acetate o Haina, ka āta whakapai ake te hanganga kaha, ka āta whakakorea te kaha whakaputa whakamuri, ā, e matapaetia ana ka piki ake te kukū o te mākete a meake nei.

I te 19 o Oketopa, ko te utu whakatau tata mō te propylene glycol methyl ether acetate ā-rohe he 9800 yuan/tana. Ko ngā whakaritenga mō te propylene glycol methyl ether acetate: 200 kg/peera 99.9% te ihirangi paerewa ā-motu. E whai mana ana te tuku mō te 1 rā. Kaiwhakarato whakatau tata: Xiamen Xiangde Supreme Chemical Products Co., LTD.

I tēnei wā, me te whanaketanga o te paninga, te waituhi, te tā me te tae, te kakahu me ētahi atu ahumahi i Haina, kei te piki haere te hiahia mākete mō te ahumahi propylene glycol methyl ether acetate o Haina, ā, kei te piki haere te tere whakaputa ā-rohe o te propylene glycol methyl ether acetate ahumahi. Heoi, he uaua te hangarau whakaputa o te propylene glycol methyl ether acetate taumata hiko, tae atu ki te taumata haurua-ira. I tēnei wā, he nui ake te wāhi hokohoko kawemai o ngā umanga ā-rohe o Haina mō te propylene glycol methyl ether acetate i roto i tēnei mara. Ka taea te whakamahi i te propylene glycol methyl ether me te propylene glycol methyl ether acetate taumata hiko hei wai whakakoi, hei horoi, hei wai tango rānei mō te whakaputa i ngā wāhanga hiko tae atu ki ngā haurua-ira, ngā papa photoresist, ngā pereti parahi-whakakikoruatia, ngā whakaaturanga karaihe wai me ētahi atu mara. Nō nā tata nei, i whakatinanahia e Haina he maha o ngā mahere "tekau mā whā rima" hei whakatenatena i te whanaketanga o te umanga rauemi hangarau-teitei me ētahi atu, ka taea e te umanga propylene glycol methyl ether acetate o Haina te tango i te hau rawhiti o te kaupapa here, te whakanui ake i te whanaketanga me te whakawhānui o te propylene glycol methyl ether acetate hiko. Me te pikinga ake o te ia o ngā whakakapinga kawemai ā-rohe ā muri ake nei, ka hangaia e te umanga propylene glycol methyl ether acetate hiko o Haina he nui te wāhi hua mō te umanga, me te uara haumi nui.
