1,2-Propyleneglycol Diacetate Propylene Glycol Diacetate PGDA CAS 623-84-7
Propylene Glycol Diacetate (PGDA, CAS 623-84-7), yomwe imatchedwanso 1,2-Propanediol diacetate, ndi chosungunulira cha diester chotentha kwambiri chomwe sichimaoneka bwino komanso chofewa, chokhala ndi fungo lochepa la ester. Chiyero ≥99.0%. Chili ndi mphamvu yotsika ya evaporation komanso mphamvu yabwino kwambiri ya acrylic, PU, alkyd ndi nitrocellulose resins. Monga m'malo abwino a cyclohexanone, isophorone, PMA ndi DBE, chimagwiritsidwa ntchito kwambiri mu zophimba zamagalimoto, zophimba ma coil, inki za PCB solder mask, zomatira zochokera m'madzi, kuyeretsa kwamagetsi molondola komanso kupangira maziko ngati chowuma cha ester chachilengedwe. Chimatumizidwa ngati katundu wamba. Nthawi yosungira: miyezi 12 pansi pa malo osungira ozizira.

1. Makampani opanga utoto: Utoto wa magalimoto, utoto wamatabwa, utoto wophikira m'mafakitale, zosungunulira zouma pang'onopang'ono zomwe zimatentha kwambiri, zimapangitsa kuti zinthu zisamayende bwino komanso kuti zisamaume bwino.
2. Inki: Inki ya PCB circuit board, inki ya intaglio / flexographic.
3. Kuyeretsa molondola pamagetsi: 1,2-Propyleneglycol diacetate yomwe imagwiritsidwa ntchito ngati chotsukira cha zida zamagetsi, yokhala ndi zotsalira zochepa.
4. Zina: Propylene glycol diacetate (PGDA) yopangidwa ndi madzi, resin synthesis solvent; water glass agent for casting; fungo lonyamulira, cosmetic solvent, pharmaceutical cosolvent.
• Kulongedza Kwachizolowezi: 220kg ng'oma; 25 kg/ng'oma
• MOQ: iyenera kutsimikiziridwa ndi giredi ndi komwe ikupita
• Nthawi Yotsogolera: kutsimikiziridwa ndi kuchuluka kwa oda ndi ndandanda yopangira
• Kutumiza: njira zotumizira panyanja / ndege / zothamanga zikupezeka
1. Malo osungira: Sungani m'nyumba yosungiramo zinthu yotsekedwa, yozizira, youma komanso yodutsa mpweya wabwino; kutentha koyenera kosungirako ndi ≤ 30℃, ndipo dzuwa liyenera kupewedwa.
2. Kusunga zinthu paokha: Sungani kutali ndi malawi otseguka ndi malo otentha kwambiri; musasunge pamodzi ndi ma oxidant amphamvu, ma acid amphamvu ndi ma alkali amphamvu kuti mupewe kusokonezeka.
3. Zofunikira pakulongedza: Sungani m'migolo yoyambirira yotsekedwa kuti mupewe kupsa ndi kulowa kwa chinyezi; limbitsani zivindikiro za migolo kuti mupewe kutuluka kwa madzi.
4. Zofunikira pakuyika milu: Ikani migolo yachitsulo yolemera makilogalamu 220 / migolo yapulasitiki pa mapaleti, muyike mokhazikika kuti musagwe; onetsetsani kuti pansi pa nyumba yosungiramo zinthu muli malo otetezedwa bwino ndi madzi.
5. Nthawi yosungira zinthu: Ngati sizikutsegulidwa komanso sizikuwonongeka, nthawi yosungira zinthuzo ndi miyezi 12. Gwiritsani ntchito mankhwalawa mwachangu mukatsegula kuti muchepetse kuuma kwa madzi ndi kuyamwa madzi.
