PPG-Poly(propylene glycol)
Wehewehena
Hiki ke hoʻoheheʻe ʻia ka moʻo PPG i nā mea hoʻoheheʻe organik e like me toluene, ethanol, a me trichloroethylene. Loaʻa iā ia kahi ākea o nā noi i ka ʻoihana, lāʻau lapaʻau, nā kemika o kēlā me kēia lā a me nā ʻoihana ʻē aʻe.

Hana a me nā noi
1. Hiki ke hoʻoheheʻe ʻia ʻo PPG200, 400, a me 600 i ka wai a he mau waiwai e like me ka lubrication, solubilization, defoaming, a me nā hopena antistatic. Hiki ke hoʻohana ʻia ʻo PPG-200 ma ke ʻano he dispersant no nā pigments.
2. I nā mea hoʻonani, hoʻohana ʻia ʻo PPG400 ma ke ʻano he emollient, softener, a me ka lubricant.
3. Hoʻohana ʻia ma ke ʻano he mea hoʻohemo i nā pena a me nā aila hydraulic, ma ke ʻano he mea hoʻohemo i ka hana ʻana o ka rubber synthetic a me ka latex, ma ke ʻano he antifreeze a me ka coolant no nā wai hoʻoili wela, a ma ke ʻano he mea hoʻololi viscosity.
4. Hoʻohana ʻia ma ke ʻano he waena i ka esterification, etherification, a me nā hopena polycondensation.
5. Hoʻohana ʻia ma ke ʻano he mea hoʻokuʻu, mea hoʻoheheʻe, a me ka mea hoʻohui no nā aila synthetic. Hoʻohana ʻia hoʻi ia ma ke ʻano he mea hoʻohui no nā wai ʻokiʻoki wai-hoʻoheheʻe ʻia, nā aila wili, a me nā aila hydraulic, ma ke ʻano he lubricant wela kiʻekiʻe, a ma ke ʻano he lubricant kūloko a me waho no ka rubber.
Loaʻa iā 6.PPG-2000~8000 nā waiwai lubricating maikaʻi loa, antifoaming, pale wela, a me ke kūpaʻa i ka hau.
Hoʻohana nui ʻia ʻo 7.PPG-3000 ~ 8000 ma ke ʻano he ʻāpana o nā polyols polyether no ka hana ʻana i nā plastics huʻa polyurethane.
Hiki ke hoʻohana pololei ʻia a i ʻole esterified ʻia ʻo 8.PPG-3000 ~ 8000 no ka hana ʻana o nā plasticizers a me nā lubricants.
