I-Propylene glycol methyl ether acetate iwuhlobo lwe-solvent ethuthukisiwe. I-molecule yayo iqukethe kokubili ibhondi ye-ether 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 i-polar 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 kanye ne-nitrocelluloses. 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.

Ngokombiko othi “2023-2027 China Propanediol methyl ether acetate (PMA) Project Investment Feasibility Study Report” ekhishwe yiXinsijie Industry Research Center, kulesi sigaba, ubuchwepheshe bokukhiqiza baseChina i-propanediol methyl ether acetate buye bathuthuka kancane kancane, ukusebenza kwayo okuphelele kuye kwathuthuka kancane kancane, insimu yayo yesicelo iye yanda kancane kancane, futhi kancane kancane ithuthuke yaba yi-semiconductor, i-photoresist substrate, ipuleti le-copper clad nezinye 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/umphongolo 99.9% okuqukethwe okusezingeni likazwelonke. Ukunikezwa kuvumeleke usuku olungu-1. Umhlinzeki wengcaphuno: Xiamen Xiangde Supreme Chemical Products Co., LTD.

Njengamanje, ngokuthuthukiswa kwezimboni zokumboza, uyinki, ukuphrinta nokudaya, izindwangu nezinye izimboni e-China, isidingo semakethe somkhakha waseChina we-propylene glycol methyl ether acetate siyakhula, nezinga lokukhiqizwa kwasekhaya kwezimboni ze-propylene glycol methyl ether acetate liyakhula. phezulu nangaphezulu. 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 nanhlanu” kuthiwa ukukhuthaza ukuthuthukiswa kwe-semiconductor kanye neminye imboni yezinto zobuchwepheshe obuphezulu, imboni yaseChina i-propylene glycol methyl ether acetate noma izokwazi ukuthatha umoya wasempumalanga wenqubomgomo, inyuse izinga. ukuthuthukiswa nokunwetshwa kwebanga le-elekthronikhi i-propylene glycol methyl ether acetate, ngomkhuba wesikhathi esizayo wokushintsha kwamanye amazwe ukhuphukile, imboni ye-electronic grade propylene glycol methyl ether acetate yaseChina izodala isikhala esiningi senzuzo yemboni, enenani elikhulu lokutshala izimali.
