I-1,2-Propyleneglycol Diacetate Propylene Glycol Diacetate PGDA CAS 623-84-7
I-Propylene Glycol Diacetate (PGDA, CAS 623-84-7), ebizwa nangokuthi i-1,2-Propanediol diacetate, iyi-solvent ye-diester ebilayo kakhulu engenambala futhi enobungani nemvelo enephunga elincane le-ester. Ubumsulwa ≥99.0%. Inezinga lokuhwamuka elimaphakathi kanye ne-solvency enhle kakhulu yama-resin e-acrylic, i-PU, i-alkyd kanye ne-nitrocellulose. Njengendawo enhle yokufaka esikhundleni se-cyclohexanone, i-isophorone, i-PMA kanye ne-DBE, isetshenziswa kabanzi ekumbozweni kwezimoto, ekumbozweni kwe-coil, kuma-inki emaski e-solder e-PCB, kuma-adhesive asekelwe emanzini, ekuhlanzweni kwe-elekthronikhi ngokunemba kanye ne-foundry njenge-organic ester hardener. Ithunyelwa njengempahla ejwayelekile. Isikhathi seshelufu: Izinyanga eziyi-12 ngaphansi kwesitoreji esivaliwe esipholile.

1. Imboni yokupenda: Upende wezimoto, upende wokhuni, upende wokubhaka wezimboni, izinyibilikisi ezomisa kancane kancane ezishisa kakhulu, ezithuthukisa ukuhleleka nokucwebezela.
2. Uyinki: Uyinki webhodi lesekethe le-PCB, uyinki we-intaglio / flexographic.
3. Ukuhlanza ngokunemba kwe-elekthronikhi: I-1,2-Propyleneglycol diacetate esetshenziswa njenge-ejenti yokuhlanza izingxenye ze-elekthronikhi, enensalela encane.
4. Ezinye: I-Propylene glycol diacetate (PGDA) ingcina esekwe emanzini, i-resin synthesis solvent; i-ejenti yokwelapha ingilazi yamanzi yokukhipha; isithwali sephunga, i-cosmetic solvent, i-pharmaceutical cosolvent.
• Ukupakisha Okujwayelekile: Isigubhu esingu-220kg; 25 kg/isigubhu
• I-MOQ: kufanele iqinisekiswe ngokwebanga nendawo oya kuyo
• Isikhathi Sokuhola: kuzoqinisekiswa ngobuningi be-oda kanye nesheduli yokukhiqiza
• Ukuthunyelwa: izinketho zolwandle / zomoya / ze-express ziyatholakala
1. Indawo yokugcina: Gcina endaweni yokugcina evaliwe, epholile, eyomile futhi enomoya omuhle; izinga lokushisa elinconywayo lokugcina lingu-≤ 30℃, futhi ukukhanya kwelanga okuqondile kufanele kugwenywe.
2. Indawo yokugcina izinto: Gcina kude namalangabi avulekile kanye nemithombo yokushisa eshisa kakhulu; ungagcini ndawonye nama-oxidants aqinile, ama-asidi aqinile kanye nama-alkali aqinile ukuvimbela ukusabela.
3. Izidingo zokupakisha: Gcina emiphongolweni yokuqala evaliwe ukuze uvimbele ukuhwamuka kanye nokungena komswakama; qinisa izivalo zemiphongolo ukuze ugweme ukuvuza.
4. Izidingo zokubeka izinqwaba: Beka imiphongolo yensimbi engu-220kg / imiphongolo yepulasitiki emaphalethini, ubeke izinqwaba ngokuqinile ukuze uvimbele ukugoba; qinisekisa ukuthi phansi kwendlu yokugcina impahla kuvikelwe kahle ngamanzi.
5. Isikhathi sokuphila eshalofini: Uma ingavulwanga futhi ingonakali, isikhathi sokugcina ngaphansi kwezimo zokugcina ezingenhla siyizinyanga eziyi-12. Sebenzisa umkhiqizo ngokushesha ngangokunokwenzeka ngemva kokuvula ukuze unciphise ukuhwamuka nokumuncwa kwamanzi.
