I-Propylene glycol methyl ether acetate luhlobo lwe-solvent ephucukileyo. I-molecule yayo iqulethe zombini i-ether bond kunye neqela le-carbonyl, kwaye iqela le-carbonyl lenza isakhiwo se-ester kwaye liqulathe iqela le-alkyl. Kwimolekyuli enye, kukho iindawo ezingezizo ze-polar kunye neendawo ze-polar, kwaye amaqela asebenzayo ala macandelo mabini awagcini nje ngokuthintela nokugxothana, kodwa adlala indima yawo yendalo. Ke ngoko, inokunyibilika okuthile kwezinto ezingezizo ze-polar kunye ne-polar. I-Propylene glycol methyl ether acetate yenziwe ngokwenziwa kwe-esterification ye-propylene glycol methyl ether kunye ne-glacial acetic acid kusetyenziswa i-concentrated sulfuric acid njenge-catalyst. Yi-solvent yezimboni ephucukileyo ekumgangatho ophantsi, inamandla okunyibilikisa izinto ze-polar kunye ne-non-polar, ezifanelekileyo kwiingubo eziphezulu, i-inki solvents ze-polymers ezahlukeneyo, kubandakanya i-aminomethyl ester, i-vinyl, i-polyester, i-cellulose acetate, i-alkyd resin, i-acrylic resin, i-epoxy resin kunye ne-nitrocelluloses. Phakathi kwazo. I-Propylene glycol methyl ether propionate yeyona nto inyibilikisayo ilungileyo kwipeyinti nakwi-inki, ifanelekile kwi-polyester engagcwaliyo, i-polyurethane resin, i-acrylic resin, i-epoxy resin njl.

Ngokutsho kwe-“2023-2027 China Propanediol methyl ether acetate (PMA) Project Investment Feasibility Study Report” ekhutshwe yiXisijie Industry Research Center, kweli nqanaba, iteknoloji yemveliso yepropanediol methyl ether acetate yaseTshayina iye yaphucuka kancinci kancinci, ukusebenza kwayo okubanzi kuye kwaphucuka kancinci kancinci, intsimi yayo yokusetyenziswa iye yanda kancinci kancinci, kwaye iye yaphuhla kancinci kancinci yaba yi-semiconductor, i-photoresist substrate, i-copper clad plate kunye nezinye iimarike. Imfuno yemarike ikhula kancinci kancinci. Phantsi kwale mvelaphi, isikali semarike yepropylene glycol methyl ether acetate eTshayina sibonisa umkhwa okhulayo unyaka nonyaka. Ukususela ngo-2015 ukuya ku-2022, ubungakanani bemarike yepropylene glycol methyl ether acetate eTshayina bunyuke ukusuka kwi-2.261 yeebhiliyoni zeerandi ukuya kwi-3.397 yeebhiliyoni zeerandi, kunye nezinga lokukhula lonyaka elihlanganisiweyo le-5.99%. Phakathi kwabo, imakethi yeekhemikhali yeTianyin ibe yeyona ininzi, ifikelela kwi-25.7%; kwalandela iHualun Chemical, i-13.8% yemarike; Kwindawo yesithathu kukho iJida Chemical, enesabelo semarike se-10.4%. Ngenxa yophuhliso oluqhubekayo lweshishini le-propylene glycol methyl ether acetate laseTshayina, isakhiwo samandla siyaphuculwa kancinci kancinci, amandla emveliso abuyela umva ayasuswa kancinci kancinci, kwaye uxinzelelo lwayo kwimarike kulindeleke ukuba lunyuke ngakumbi kwixesha elizayo.

Ngomhla we-19 kweyeDwarha, isicatshulwa se-propylene glycol methyl ether acetate yasekhaya yayiyi-9800 yuan/ton. Iinkcukacha ze-propylene glycol methyl ether acetate: 200 kg/barrel 99.9% umxholo osemgangathweni wesizwe. Esi sibonelelo sisebenza usuku olu-1. Umboneleli wesicatshulwa: Xiamen Xiangde Supreme Chemical Products Co., LTD.

Okwangoku, ngophuhliso lwe-coating, i-inki, ukushicilela kunye nokudaya, i-textile kunye nezinye izimboni eTshayina, imfuno yemarike yeshishini laseTshayina le-propylene glycol methyl ether acetate iyanda, kwaye izinga lemveliso yasekhaya ye-industrial propylene glycol methyl ether acetate liya lisanda. Nangona kunjalo, itekhnoloji yemveliso ye-electronic grade kunye ne-semiconductor grade propylene glycol methyl ether acetate inzima kakhulu. Okwangoku, amashishini asekuhlaleni aseTshayina e-propylene glycol methyl ether acetate anendawo enkulu yokutshintsha imarike yokungenisa kweli candelo. I-electronic grade propylene glycol methyl ether kunye ne-propylene glycol methyl ether acetate zingasetyenziswa njenge-diluent, i-cleaning agent okanye i-stripping liquid ukuvelisa izinto ze-elektroniki kubandakanya ii-semiconductors, ii-photoresist substrates, ii-copper-clad plates, ii-liquid crystal displays kunye nezinye iindawo. Kutshanje iTshayina iqalise isicwangciso se-"14 five" esikhankanyiweyo ukukhuthaza uphuhliso lweshishini lezinto ze-semiconductor kunye nezinye izinto zobugcisa obuphezulu, ishishini laseTshayina le-propylene glycol methyl ether acetate okanye liya kukwazi ukuthatha umoya wasempuma womgaqo-nkqubo, linyuse uphuhliso kunye nokwandiswa kwe-electronic grade propylene glycol methyl ether acetate, kunye nomkhwa wokutshintshwa kwe-intanethi yasekhaya ozayo onyukileyo, ishishini laseTshayina le-electronic grade propylene glycol methyl ether acetate liya kudala indawo eninzi yenzuzo kushishino, ngexabiso elikhulu lotyalo-mali.
