He aha ka Poly(propylene glycol) CAS 25322-69-4?

ʻO ka poly(propylene glycol) he polymer me kahi wai wai melemele ʻole. Hiki ke hoʻoheheʻe ʻia i loko o ka wai (ke kaumaha molekala haʻahaʻa) a me nā mea hoʻoheheʻe kūlohelohe e like me nā aliphatic ketones a me nā waiʻona, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i ka ether a me ka hapa nui o nā aliphatic hydrocarbons. Loaʻa iā ia ma ka condensation o propylene oxide a propylene glycol ma lalo o ke kaomi kiʻekiʻe a i ʻole ma ke alo o kahi catalyst acidic.

1. Hiki ke hoʻoheheʻe ʻia nā moʻo PPG i loko o nā mea hoʻoheheʻe kūlohelohe e like me toluene, ethanol, trichloroethylene, etc. ʻO PPG200, 400, a me 600 he mea hiki ke hoʻoheheʻe ʻia i ka wai a loaʻa ka lubricating, soliloquizing, defaming, a me nā waiwai antistatic. Hiki ke hoʻohana ʻia ka PPG-200 ma ke ʻano he dispersant no nā puaʻa.

2. Ma nā mea hoʻonani, hoʻohana ʻia ʻo PPG400 e like me ka emollient, softener, a me ka lubricant.

3. Hoʻohana ʻia ʻo Poly(propylene glycol) ma ke ʻano he anti-foaming agent i nā uhi a me nā aila hydraulic, kahi antifoaming agent i ka synthetic rubber a me ka hana latex, kahi refrigerant a me ka mea hoʻomaha no nā wai hoʻoili wela, a me ka hoʻomaikaʻi viscosity.

4. Hoʻohana ʻia ka Poly(propylene glycol) ma ke ʻano he waena no ka esterification, etherification, a me ka polycondensation reactions.

5. Hoʻohanaʻia ka Poly(propylene glycol) ma keʻano he mea hoʻokuʻu, he mea hoʻoheheʻe, he mea hoʻohui no nāʻaila synthetic, he mea hoʻohui no nā waiʻokiʻoki wai, nāʻaila wili, nāʻaila hydraulic, nā lubricants kiʻekiʻe, a me nā lubricants i loko a me waho no ka'ōpala.

6. PPG-2000 ~ 8000 he lubrication maikaʻi loa, anti-foaming, wela a me ka hau a me nā waiwai'ē aʻe;

7. Hoʻohana nui ʻia ʻo PPG-3000 ~ 8000 ma ke ʻano he ʻāpana o ka polyether i hui pū ʻia e hana i nā plastic foam polyurethane;

8. PPG-3000 ~ 8000 hiki ke hoʻohana pololei a ma hope o ka esterification e hana i nā plasticizers a me nā lubricants;
