PPG-Poly (propylene glycol)
Kufotokozera
Mndandanda wa PPG umasungunuka mu zinthu zosungunulira zachilengedwe monga toluene, ethanol, ndi trichloroethylene. Uli ndi ntchito zosiyanasiyana m'mafakitale, mankhwala, mankhwala a tsiku ndi tsiku ndi madera ena.

Magwiridwe antchito ndi Mapulogalamu
1.PPG200, 400, ndi 600 zimasungunuka m'madzi ndipo zimakhala ndi mphamvu monga mafuta, kusungunuka, kuchotsa poizoni, komanso mphamvu zotsutsana ndi static. PPG-200 ingagwiritsidwe ntchito ngati chosungunula utoto.
2. Mu zodzoladzola, PPG400 imagwiritsidwa ntchito ngati mafuta odzola, ofewetsa, komanso mafuta odzola.
3. Amagwiritsidwa ntchito ngati chotsukira makwinya mu utoto ndi mafuta a hydraulic, ngati chotsukira makwinya pokonza mphira wopangidwa ndi latex, ngati choletsa kuzizira komanso choziziritsa kutentha, komanso ngati chosinthira kukhuthala.
4. Amagwiritsidwa ntchito ngati chothandizira pa esterification, etherification, ndi polycondensation reactions.
5. Amagwiritsidwa ntchito ngati chotulutsira, chosungunula, komanso chowonjezera pa mafuta opangidwa. Amagwiritsidwanso ntchito ngati chowonjezera pa madzi odulira osungunuka m'madzi, mafuta ozungulira, ndi mafuta a hydraulic, ngati mafuta otentha kwambiri, komanso ngati mafuta amkati ndi akunja a rabara.
6.PPG-2000~8000 ili ndi mafuta abwino kwambiri, oletsa thovu, osatentha, komanso osazizira.
7.PPG-3000~8000 imagwiritsidwa ntchito makamaka ngati gawo la polyether polyols popanga mapulasitiki a thovu la polyurethane.
8.PPG-3000~8000 ingagwiritsidwe ntchito mwachindunji kapena kupangidwa kuti ipange mapulasitiki ndi mafuta odzola.
Phukusi ndi Kusungirako
Phukusi:Migolo ya 200L/1000L
Kusungira: Iyenera kuyikidwa pamalo ouma, opumira mpweya, ngati yasungidwa bwino, nthawi yosungiramo zinthu ndi zaka ziwiri.
