Propylene glycol methyl ether acetate ni ubwoko bw'umusemburo uteye imbere. Molekile yayo irimo umugozi wa ether n'itsinda rya karuboni, kandi itsinda rya karuboni rigize imiterere ya ester kandi rikagira itsinda rya alkyl. Muri molekile imwe, harimo ibice bitari polar n'ibice biri polar, kandi amatsinda y'imikorere y'ibi bice bibiri ntabwo abuzanya gusa kandi agakururana, ahubwo anagira uruhare rwayo. Kubwibyo, ifite ubushobozi bwo gushonga ku bintu bitari polar n'ibitari polar. Propylene glycol methyl ether acetate yakozwe binyuze mu gupima propylene glycol methyl ether na aside glacial acetic hakoreshejwe aside sulfuric nyinshi nk'umusemburo. Ni umusemburo mwiza cyane uteye imbere mu nganda, ufite ubushobozi bukomeye bwo gushonga ibintu biri polar n'ibitari polar, bikwiriye gupfukwa ku rwego rwo hejuru, imyuka ya wino ya polymer zitandukanye, harimo aminomethyl ester, vinyl, polyester, cellulose acetate, alkyd resin, acrylic resin, epoxy resin na nitrocelluloses. Muri byo harimo. Propylene glycol methyl ether propionate ni yo solvent nziza cyane mu irangi no mu irangi, ikwiriye polyester idafite amazi, polyurethane resin, acrylic resin, epoxy resin n'ibindi.

Nk’uko bigaragara muri “Raporo y’Inyigo y’Ishoramari ry’Umushinga wa Propanediol methyl ether acetate (PMA) wo mu Bushinwa” yashyizwe ahagaragara n’Ikigo cy’Ubushakashatsi ku Nganda cya Xinsijie, muri iki cyiciro, ikoranabuhanga ryo gukora propanediol methyl ether acetate mu Bushinwa ryagiye ritera imbere buhoro buhoro, imikorere yaryo yose yarushijeho kwiyongera buhoro buhoro, aho rikoreshwa ryagiye ritera imbere buhoro buhoro, kandi ryagiye ritera imbere buhoro buhoro rihinduka semiconductor, photoresist substrate, copper clad plate n’andi masoko. Ubukene bw’isoko burimo kwiyongera buhoro buhoro. Muri iyi ngingo, urwego rw’isoko rwa propylene glycol methyl ether acetate mu Bushinwa rugaragaza ko rugenda rwiyongera umwaka ku mwaka. Kuva mu 2015 kugeza mu 2022, ingano y’isoko rya propylene glycol methyl ether acetate mu Bushinwa yiyongereye kuva kuri miliyari 2.261 z’amayuan igera kuri miliyari 3.397 z’amayuan, aho igipimo cy’iterambere ry’umwaka kingana na 5.99%. Muri bo, isoko rya Tianyin ry’ibinyabutabire ryagize uruhare runini, rigera kuri 25.7%; Hualun Chemical yakurikiyeho, ingana na 13.8% by’isoko; Ku mwanya wa gatatu hari Jida Chemical, ifite isoko rya 10.4%. Bitewe n’iterambere rikomeje ry’inganda za propylene glycol methyl ether acetate zo mu Bushinwa, imiterere y’ubushobozi iragenda ivugururwa buhoro buhoro, ubushobozi bwo gukora bugenda bugabanuka buhoro buhoro, kandi biteganijwe ko isoko ryayo rizakomeza kwiyongera mu gihe kizaza.

Ku ya 19 Ukwakira, ibiciro bya propylene glycol methyl ether acetate yo mu gihugu byari 9800 yuan/toni. Ibipimo bya propylene glycol methyl ether acetate: 200 kg/umunwa 99.9% by'ibipimo ngenderwaho by'igihugu. Iki giciro kiramara umunsi umwe. Umutanga ibiciro: Xiamen Xiangde Supreme Chemical Products Co., LTD.

Muri iki gihe, bitewe n’iterambere ry’inganda zikora irangi, wino, icapiro n’irangi, imyenda n’izindi nganda mu Bushinwa, isoko ry’inganda zikora irangi rya propylene glycol methyl ether acetate mu Bushinwa ririmo kwiyongera, kandi igipimo cy’umusaruro w’inganda zikora irangi rya propylene glycol methyl ether acetate mu gihugu kirimo kwiyongera. Ariko, ikoranabuhanga ryo gukora irangi rya elegitoroniki ndetse n’irya semiconductor grade propylene glycol methyl ether acetate riragoye cyane. Muri iki gihe, ibigo byo mu Bushinwa bikorera muri propylene glycol methyl ether acetate bifite umwanya munini wo gusimbuza isoko ry’ibicuruzwa bitumiza mu mahanga muri uru rwego. Propylene glycol methyl ether na propylene glycol methyl ether acetate bishobora gukoreshwa nk’umuti wo gushonga, gusukura cyangwa gusohora amazi mu gukora ibikoresho by’ikoranabuhanga birimo semiconductors, photoresist substrates, ibyuma bipfutse umuringa, liquid crystal displays n’ibindi. Ubushinwa buherutse gutangiza gahunda nyinshi za "cumi nane na gatanu" zivugwaho guteza imbere inganda za semiconductor n'izindi zikora ibikoresho by'ikoranabuhanga rigezweho, inganda za propylene glycol methyl ether acetate zo mu Bushinwa cyangwa zizashobora gufata umuyaga w'iburasirazuba wa politiki, kongera iterambere no kwagura propylene glycol methyl ether acetate, hamwe n'icyerekezo cyo gusimbuza ibicuruzwa biva mu gihugu imbere mu gihe kizaza, inganda za propylene glycol methyl ether acetate zo mu Bushinwa zizatanga umwanya munini w'inyungu ku nganda, zifite agaciro gakomeye mu ishoramari.
