PPG-Poly(propylene glycol)
wehewehe
Hiki ke hoʻoheheʻe ʻia ka moʻo PPG i nā mea hoʻoheheʻe organik e like me toluene, ethanol, a me trichloroethylene. He nui nā ʻano 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
ʻO 1.PPG200, 400, a me 600 hiki ke hoʻoheheʻe ʻia i ka wai a loaʻa nā waiwai e like me ka lubrication, solubilization, defoaming, a me nā hopena antistatic. Hiki ke hoʻohana ʻia ka PPG-200 ma ke ʻano he dispersant no nā puaʻa.
2.In cosmetics, PPG400 hoʻohana 'ia e like me ka emollient, softener, a me ka lubricant.
3. Hoʻohanaʻia ma keʻano he mea hoʻoheheʻe i ka pena a me kaʻaila hydraulic, ma keʻano he mea hoʻoheheʻe i ka hanaʻana i ka synthetic rubber a me ka latex, ma keʻano he antifreeze a me ka mea hoʻomaha no nā wai hoʻoili wela, a ma keʻano he viscosity modifier.
4. Hoʻohana ʻia ma ke ʻano he waena i ka esterification, etherification, a me ka polycondensation reactions.
5.Hoʻohanaʻia ma keʻano he mea hoʻokuʻu, solubilizer, a me nā mea hoʻohui no nāʻaila synthetic. Hoʻohana ʻia ʻo ia ma ke ʻano he mea hoʻohui no nā wai ʻoki ʻoki i ka wai, nā ʻaila wili, a me nā ʻaila hydraulic, ma ke ʻano he lubricant wela kiʻekiʻe, a ma ke ʻano he lubricant kūloko a me waho no ka rubber.
6.PPG-2000~8000 loaʻa i ka lubricating maikaʻi loa, antifoaming, wela, a me ka hau.
Hoʻohana nui ʻia ʻo 7.PPG-3000 ~ 8000 ma ke ʻano he ʻāpana o ka polyether polyols no ka hana ʻana i nā plastic foam polyurethane.
8.PPG-3000 ~ 8000 hiki ke hoʻohana ponoʻia aiʻole esterified no ka hanaʻana i nā plasticizers a me nā lubricants.
Pūʻolo a me ka waiho ʻana
Pūʻolo:200L/1000L barela
Ka mālama ʻana: Pono e waiho ʻia i kahi maloʻo, wahi e hoʻoheheʻe ʻia, inā mālama maikaʻi ʻia, ʻo 2 mau makahiki ke ola.
