O le propylene glycol methyl ether acetate o se ituaiga o solvent maualuga. O lona mole e aofia uma ai le eter bond ma le carbonyl group, ma o le carbonyl group e fausia ai le fausaga o le ester ma e aofia ai le vaega alkyl. I totonu o le mole lava e tasi, o loʻo i ai uma vaega e le o polar ma vaega polar, ma o vaega faʻatino o nei vaega e lua e le gata ina faʻatapulaaina ma faʻasalaina e le tasi le isi, ae o loʻo taʻalo foi a latou matafaioi. O le mea lea, o loʻo i ai se solubility faʻapitoa mo mea e le polar ma polar. O le propylene glycol methyl ether acetate na fa'apipi'iina e ala i le esterification o le propylene glycol methyl ether ma le suka acetic acid e fa'aaoga ai le sulfuric acid fa'atosina e fai ma fa'amalosi. O se mea e sili ona lelei le maualalo o le faʻaleagaina o mea gaosi oloa, e iai se malosi malosi e faʻamalo ai mea polar ma mea e le o ni polar, e talafeagai mo faʻapipiʻi maualuga, vaitusi vaitusi o polymers eseese, e aofia ai aminomethyl ester, vinyl, polyester, cellulose acetate, alkyd resin, acrylic resin, epoxy resin ma nitrocelluloses. Faatasi ai ma i latou. O le propylene glycol methyl ether propionate o le solvent sili ona lelei i le vali ma le vaitusi, e talafeagai mo polyester unsaturated, polyurethane resin, acrylic resin, epoxy resin ma isi.
E tusa ai ma le "2023-2027 China Propanediol methyl ether acetate (PMA) Project Investment Feasibility Study Report" na tuʻuina atu e le Xinsijie Industry Research Center, i le taimi nei, ua faasolosolo malie ona faʻaleleia le tekonolosi o le gaosiga o le propanediol methyl ether acetate a Saina, ua faasolosolo malie ona faʻaleleia lona faʻatinoga atoatoa, ua faasolosolo malie ona faʻalauteleina lona faʻaogaina, ma faasolosolo malie ona faʻalauteleina, ipu apamemea ma isi maketi. O loʻo faʻasolosolo malie le manaʻoga o maketi. I lalo o lenei talaaga, o le maketi o le propylene glycol methyl ether acetate i Saina o loʻo faʻaalia ai le faʻatupulaia o le tulaga i lea tausaga ma lea tausaga. Mai le 2015 i le 2022, o le maketi o le propylene glycol methyl ether acetate i Saina na siitia mai le 2.261 piliona yuan i le 3.397 piliona yuan, faatasi ai ma le fua faatatau o le tuputupu ae faaletausaga o le 5.99%. Faatasi ai ma i latou, Tianyin chemical market accounted mo le tele o vaega, e oʻo atu i le 25.7%; Na sosoo ai ma Hualun Chemical, e tusa ma le 13.8% o le maketi; I le tulaga tolu o le Jida Chemical, faʻatasi ai ma le maketi o le 10.4%. Faatasi ai ma le faʻaauauina pea o le atinaʻeina o le propylene glycol methyl ether acetate alamanuia a Saina, o le fausaga o le gafatia e faasolosolo malie ona faʻaleleia, o le gaosiga o le gaosiga i tua e faasolosolo malie lava ona faʻaumatia, ma o lona faʻatauga maketi e faʻamoemoe e faʻateleina i le lumanaʻi.
O Oketopa 19, o le upusii o fale propylene glycol methyl ether acetate o 9800 yuan / tone. Fa'amatalaga o le propylene glycol methyl ether acetate: 200 kilokalama / paelo 99.9% tulaga fa'ale-malo. O le ofo e aoga mo le 1 aso. Tuuina atu o upusii: Xiamen Xiangde Supreme Chemical Products Co., LTD.
I le taimi nei, faʻatasi ai ma le atinaʻeina o le faʻapipiʻiina, vaitusi, lomitusi ma le valiina, ie ma isi pisinisi i Saina, o loʻo faʻatupulaia le manaʻomia o maketi a Saina propylene glycol methyl ether acetate alamanuia, ma o loʻo faʻatupulaia le maualuga o le gaosiga o le gaosiga o fale gaosi oloa propylene glycol methyl ether acetate. Ae ui i lea, o le gaosiga o tekinolosi o le eletise eletise ma e oʻo lava i le semiconductor grade propylene glycol methyl ether acetate e faigata tele. I le taimi nei, o pisinisi faʻapitonuʻu a Saina o le propylene glycol methyl ether acetate o loʻo i ai se avanoa sili atu e sui ai maketi i totonu o lenei fanua. E mafai ona faʻaaogaina le propylene glycol methyl ether acetate ma le propylene glycol methyl ether acetate e pei o le diluent, faʻamama poʻo le tapeina o le vai mo le gaosiga o mea faʻaeletoroni e aofia ai semiconductors, photoresist substrates, ipu apamemea, faʻaaliga tioata vai ma isi fanua. Saina talu ai nei faailoa mai se numera o le "sefulufa lima" fuafuaga o loo taʻua e uunaia ai le atinae o semiconductor ma isi alamanuia mea faatekinolosi, o Saina propylene glycol methyl eter acetate alamanuia po o le a mafai ona ave le matagi sasaʻe o le faiga faavae, laa i luga le atinae ma le faalauteleina o le faaeletonika vasega propylene glycol methyl eter acetate, faatasi ai ma le lumanai oloa faaulufale mai totonu o le eletise methyl acetate alamanuia o le a siitia ai le gaosiga o oloa gaosi oloa gaosi oloa gaosi oloa gaosi oloa gaosi oloa gaosi oloa gaosi oloa gaosi oloa gaosi oloa gaosi oloa gaosi oloa gaosi oloa gaosi oloa a Saina i le lumanai. tele avanoa avanoa mo le alamanuia, ma le tele o tupe teu fa'afaigaluega.
