Kodi Poly(propylene glycol) CAS 25322-69-4 ndi chiyani?

Poly(propylene glycol) ndi polima yokhala ndi mawonekedwe amadzimadzi opanda mtundu mpaka achikasu. Imasungunuka m'madzi (kulemera kwa maselo otsika) ndi zosungunulira zachilengedwe monga ma ketones aliphatic ndi ma alcohols, koma osasungunuka mu ether ndi ma hydrocarbon ambiri aliphatic. Imapezedwa ndi condensation ya propylene oxide ndi propylene glycol pansi pa kuthamanga kwakukulu kapena pamaso pa chothandizira acidic.

Kugwiritsa ntchito

1. PPG mndandanda ndi sungunuka mu zosungunulira organic monga toluene, Mowa, trichlorethylene, etc. PPG200, 400, ndi 600 ndi sungunuka m'madzi ndi lubricating, soliloquizing, kuipitsa mbiri, ndi katundu antistatic. PPG-200 itha kugwiritsidwa ntchito ngati dispersant kwa inki.

2. Mu zodzoladzola, PPG400 imagwiritsidwa ntchito ngati mafuta, ofewetsa, komanso mafuta.

3. Poly(propylene glycol) imagwiritsidwa ntchito ngati anti-foaming agent mu zokutira ndi mafuta a hydraulic, antifoaming agent mu mphira wopangidwa ndi latex processing, refrigerant ndi ozizira kwa madzi otumizira kutentha, ndi kuwongolera kukhuthala.

4. Poly(propylene glycol) imagwiritsidwa ntchito ngati njira yapakatikati ya esterification, etherification, ndi polycondensation reaction.

5. Poly (propylene glycol) imagwiritsidwa ntchito ngati chotulutsa, chosungunula, chowonjezera cha mafuta opangira, chowonjezera cha madzi osungunuka amadzimadzi, mafuta odzigudubuza, mafuta a hydraulic, mafuta otentha kwambiri, ndi mafuta amkati ndi kunja kwa mphira.

6. PPG-2000 ~ 8000 ili ndi mafuta abwino kwambiri, odana ndi thovu, kutentha ndi kukana chisanu ndi zinthu zina;

7. PPG-3000 ~ 8000 makamaka ntchito ngati chigawo chimodzi cha poliyesitsa ophatikizana kupanga polyurethane thovu mapulasitiki;

8. PPG-3000 ~ 8000 angagwiritsidwe ntchito mwachindunji kapena pambuyo esterification kupanga plasticizers ndi lubricant;
