I-Propylene glycol methyl ether acetate iwuhlobo lwe-solvent ethuthukisiwe. I-molecule yayo iqukethe kokubili i-ether bond neqembu le-carbonyl, futhi iqembu le-carbonyl lakha isakhiwo se-ester futhi liqukethe iqembu le-alkyl. Ku-molecule efanayo, kukhona kokubili izingxenye ezingezona ze-polar nezingxenye ze-polar, futhi amaqembu asebenzayo alezi zingxenye ezimbili awagcini nje ukukhawulela futhi axoshe omunye nomunye, kodwa futhi adlale indima yawo yemvelo. Ngakho-ke, ine-solubility ethile yazo zombili izinto ezingezona ezomhlaba kanye ne-polar. I-Propylene glycol methyl ether acetate yahlanganiswa nge-esterification ye-propylene glycol methyl ether kanye ne-glacial acetic acid kusetshenziswa i-sulfuric acid egxilile njenge-catalyst. Kuyi-solvent yezimboni ezithuthukisiwe ezinobuthi obuphansi kakhulu, inekhono eliqinile lokuncibilikisa izinto ezipholile nezingezona i-polar, ezifanele ukumbozwa kwezinga eliphezulu, izincibilikisi zikayinki zama-polymer ahlukahlukene, okuhlanganisa i-aminomethyl ester, i-vinyl, i-polyester, i-cellulose acetate, i-alkyd resin, i-acrylic resin, i-epoxy resin ne-nitrocellulose. Phakathi kwazo. I-Propylene glycol methyl ether propionate iyi-solvent engcono kakhulu kupende noyinki, ifanele i-polyester engagcwele, i-polyurethane resin, i-acrylic resin, i-epoxy resin njalonjalo.

Ngokusho kwe-"2023-2027 China Propanediol methyl ether acetate (PMA) Project Investment Feasibility Study Report" ekhishwe yiXinsijie Industry Research Center, kulesi sigaba, ubuchwepheshe bokukhiqiza baseChina be-propanediol methyl ether acetate buye bathuthuka kancane kancane, ukusebenza kwayo okuphelele kuye kwathuthuka kancane kancane, insimu yayo yokusetshenziswa iye yanda kancane kancane, futhi kancane kancane iye yathuthuka yaba enye ipuleti le-corolla. izimakethe. Isidingo semakethe sikhula kancane kancane. Ngaphansi kwalesi sizinda, isikali semakethe se-propylene glycol methyl ether acetate e-China sibonisa ukuthambekela okukhulayo unyaka nonyaka. Kusukela ngo-2015 kuya ku-2022, usayizi wemakethe we-propylene glycol methyl ether acetate e-China unyuke usuka ku-2.261 billion wamayuan waya kuma-yuan ayizigidi eziyizinkulungwane ezingu-3.397, ngenani lokukhula elihlanganisiwe lonyaka elingu-5.99%. Phakathi kwabo, imakethe yamakhemikhali ye-Tianyin ibalwa ingxenye enkulu, ifinyelela ku-25.7%; I-Hualun Chemical ilandelwe, ibala u-13.8% wemakethe; Endaweni yesithathu kukhona iJida Chemical, enesabelo semakethe esingu-10.4%. Ngokuthuthuka okuqhubekayo komkhakha waseChina we-propylene glycol methyl ether acetate, isakhiwo samandla siyathuthukiswa kancane kancane, amandla okukhiqiza ahlehla kancane kancane aqedwe, futhi ukugxilwa kwayo kwemakethe kulindeleke ukuthi kukhule ngokuzayo.

Ngo-Okthoba 19, ikhotheshini ye-propylene glycol methyl ether acetate yasekhaya yayingu-9800 yuan/ton. Imininingwane ye-propylene glycol methyl ether acetate: 200 kg/umgqomo 99.9% okuqukethwe okujwayelekile kukazwelonke. Ukunikezwa kuvumeleke usuku olungu-1. Umhlinzeki wengcaphuno: Xiamen Xiangde Supreme Chemical Products Co., LTD.

Njengamanje, ngokuthuthukiswa kwezimboni zokumboza, uyinki, ukuphrinta nokudaya, izindwangu nezinye izimboni eShayina, isidingo semakethe somkhakha waseChina we-propylene glycol methyl ether acetate siyakhula, nezinga lokukhiqizwa kwasekhaya kwe-industrial propylene glycol methyl ether acetate liya ngokuya likhuphuka. Kodwa-ke, ubuchwepheshe bokukhiqiza bebanga le-elekthronikhi kanye nebanga le-semiconductor ye-propylene glycol methyl ether acetate bunzima kakhulu. Njengamanje, amabhizinisi endawo ase-China e-propylene glycol methyl ether acetate anendawo enkulu yokushintshanisa imakethe yokungenisa kwamanye amazwe kulo mkhakha. I-Electronic grade propylene glycol methyl ether kanye ne-propylene glycol methyl ether acetate ingasetshenziswa njenge-diluent, i-ejenti yokuhlanza noma uketshezi olukhumulayo ukuze kukhiqizwe izingxenye ze-elekthronikhi ezihlanganisa ama-semiconductors, ama-photoresist substrates, amapuleti agqoke ithusi, imibukiso yekristalu ewuketshezi neminye imikhakha. I-China isanda kwethula uhlelo oluningi “lweshumi nane” okukhulunywa ngalo ukukhuthaza ukuthuthukiswa kwe-semiconductor kanye nezinye imboni yezinto zokwakha zobuchwepheshe obuphezulu, imboni yaseChina ye-propylene glycol methyl ether acetate noma izokwazi ukuthatha umoya wasempumalanga wenqubomgomo, ikhuphule ukuthuthukiswa nokunwetshwa kwe-electronic grade propylene glycol methyl ether acetate, ne-propylene glycol glycol grade ye-acetate yasekhaya yanda imboni ye-methyl ether acetate izodala indawo enkulu yenzuzo yemboni, enenani elikhulu lokutshala imali.
