I-Propylene glycol methyl ether acetate uhlobo lwesinyibilikisi esithuthukisiwe. I-molecule yayo iqukethe isibopho se-ether kanye neqembu le-carbonyl, kanti iqembu le-carbonyl lakha isakhiwo se-ester futhi liqukethe iqembu le-alkyl. Ku-molecule efanayo, kunezingxenye ezingezona i-polar kanye nezingxenye ze-polar, futhi amaqembu asebenzayo alezi zingxenye ezimbili awagcini nje ngokuvimbelana nokuxoshana, kodwa futhi adlala indima yawo engokwemvelo. Ngakho-ke, inokuncibilika okuthile kwezinto ezingezona i-polar kanye ne-polar. I-Propylene glycol methyl ether acetate yakhiwe ngokwenziwa kwe-ester kwe-propylene glycol methyl ether kanye ne-glacial acetic acid kusetshenziswa i-concentrated sulfuric acid njenge-catalyst. Iyi-solvent yezimboni ethuthukisiwe esezingeni eliphezulu, inekhono elinamandla lokuncibilikisa izinto ezingezona i-polar kanye ne-non-polar, ezifanele ukumbozwa kwezinga eliphezulu, izinyibilikisi ze-inki zama-polymer ahlukahlukene, kufaka phakathi 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 iyisisombululo esihle kakhulu sopende noyinki, esifanele i-polyester engagcwali, i-polyurethane resin, i-acrylic resin, i-epoxy resin njalo njalo.

Ngokusho kwe-“2023-2027 China Propanediol methyl ether acetate (PMA) Project Feasibility Study Report” ekhishwe yi-Xisijie Industry Research Center, kulesi sigaba, ubuchwepheshe bokukhiqiza i-propanediol methyl ether acetate yaseShayina buye bathuthuka kancane kancane, ukusebenza kwayo okuphelele kuye kwathuthuka kancane kancane, insimu yayo yokusetshenziswa iye yanda kancane kancane, futhi iye yathuthuka kancane kancane yaba yi-semiconductor, i-photoresist substrate, i-copper clad plate kanye nezinye izimakethe. Isidingo semakethe siyakhula kancane kancane. Ngaphansi kwalesi sizinda, isilinganiso semakethe se-propylene glycol methyl ether acetate eShayina sibonisa ukuthambekela okwandayo unyaka nonyaka. Kusukela ngo-2015 kuya ku-2022, usayizi wemakethe we-propylene glycol methyl ether acetate eShayina ukhuphuke kusuka ku-2.261 billion yuan kuya ku-3.397 billion yuan, ngesilinganiso sokukhula sonyaka esihlanganisiwe esingu-5.99%. Phakathi kwabo, imakethe yamakhemikhali ye-Tianyin yaba nengxenye enkulu kunazo zonke, yafinyelela ku-25.7%; kwalandela i-Hualun Chemical, ebalelwa ku-13.8% wemakethe; Endaweni yesithathu kukhona iJida Chemical, enesabelo semakethe esingu-10.4%. Njengoba imboni ye-propylene glycol methyl ether acetate yaseShayina iqhubeka nokuthuthuka, isakhiwo samandla siyathuthukiswa kancane kancane, amandla okukhiqiza abuyela emuva ancishiswa kancane kancane, futhi ukuhlushwa kwayo emakethe kulindeleke ukuthi kukhule kakhulu esikhathini esizayo.

Ngomhlaka-19 Okthoba, ikhotheshini ye-propylene glycol methyl ether acetate yasekhaya yayingu-9800 yuan/ton. Imininingwane ye-propylene glycol methyl ether acetate: 200 kg/barrel 99.9% okuqukethwe okujwayelekile kuzwelonke. Lesi sipho sisebenza usuku olu-1. Umhlinzeki wekhotheshini: Xiamen Xiangde Supreme Chemical Products Co., LTD.

Njengamanje, ngokuthuthukiswa kokumboza, uyinki, ukuphrinta nokudaya, izindwangu kanye nezinye izimboni eShayina, isidingo semakethe semboni ye-propylene glycol methyl ether acetate yaseShayina siyakhula, futhi izinga lokukhiqizwa kwasekhaya kwe-propylene glycol methyl ether acetate yezimboni liya ngokuya likhuphuka. Kodwa-ke, ubuchwepheshe bokukhiqiza be-propylene glycol methyl ether acetate ye-elekthronikhi kanye neye-semiconductor grade bunzima kakhulu. Njengamanje, amabhizinisi endawo aseShayina e-propylene glycol methyl ether acetate anendawo enkulu yokufaka esikhundleni emakethe yokungenisa kuleli nsimu. I-propylene glycol methyl ether ye-elekthronikhi kanye ne-propylene glycol methyl ether acetate ye-elekthronikhi ingasetshenziswa njenge-diluent, i-ejenti yokuhlanza noma i-stripping liquid yokukhiqiza izingxenye ze-elekthronikhi ezifaka phakathi ama-semiconductor, ama-substrate e-photoresist, amapuleti e-copper-clad, ama-liquid crystal displays kanye neminye imikhakha. Muva nje iShayina yethule uhlelo oluningi “oluyishumi nane nanhlanu” okukhulunywa ngalo ukukhuthaza ukuthuthukiswa kwemboni yezinto ze-semiconductor kanye nezinye izinto zobuchwepheshe obuphezulu, imboni yaseShayina ye-propylene glycol methyl ether acetate noma izokwazi ukuthatha umoya wasempumalanga wenqubomgomo, ithuthukise ukuthuthukiswa nokwandiswa kwe-electronic grade propylene glycol methyl ether acetate, njengoba umkhuba wesikhathi esizayo wokufaka esikhundleni sokungenisa ngaphakathi ukhuphuka, imboni yaseShayina ye-electronic grade propylene glycol methyl ether acetate izodala isikhala esikhulu senzuzo embonini, ngenani elikhulu lokutshalwa kwezimali.
