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

Poly (propylene glycol) ndi polima yokhala ndi mawonekedwe amadzimadzi opanda mtundu kapena achikasu owala. Imasungunuka m'madzi (kulemera kochepa kwa mamolekyulu) ndi zosungunulira zachilengedwe monga aliphatic ketones ndi alcohols, koma siisungunuka mu ether ndi ma aliphatic hydrocarbons ambiri. Imapezeka mwa kusungunuka kwa propylene oxide ndi propylene glycol pansi pa kupanikizika kwakukulu kapena pamaso pa chothandizira cha acidic.

Kugwiritsa ntchito

1. Mndandanda wa PPG umasungunuka mu zinthu zosungunulira zachilengedwe monga toluene, ethanol, trichloroethylene, ndi zina zotero. PPG200, 400, ndi 600 zimasungunuka m'madzi ndipo zimakhala ndi mafuta odzola, osungunulira, odetsa dzina, komanso oletsa kusinthasintha kwa kutentha. PPG-200 ingagwiritsidwe ntchito ngati chosungunulira utoto.

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

3. Poly (propylene glycol) imagwiritsidwa ntchito ngati choletsa thovu mu zokutira ndi mafuta a hydraulic, choletsa thovu mu rabara yopangidwa ndi latex, choziziritsira ndi choziziritsira cha madzi otumizira kutentha, komanso chowonjezera kukhuthala kwa viscosity.

4. Poly (propylene glycol) imagwiritsidwa ntchito ngati chothandizira pa esterification, etherification, ndi polycondensation reactions.

5. Poly (propylene glycol) imagwiritsidwa ntchito ngati chotulutsira madzi, chosungunula, chowonjezera cha mafuta opangidwa, chowonjezera cha madzi odulira osungunuka m'madzi, mafuta ozungulira, mafuta a hydraulic, mafuta otentha kwambiri, ndi mafuta amkati ndi akunja a rabara.

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

7. PPG-3000~8000 imagwiritsidwa ntchito makamaka ngati gawo la polyether yosakanikirana kuti ipange mapulasitiki a thovu la polyurethane;

8. PPG-3000~8000 ingagwiritsidwe ntchito mwachindunji kapena pambuyo pa esterification kuti ipange mapulasitiki ndi mafuta odzola;
