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

He polymer ka Poly(propylene glycol) me ke ʻano wai melemele ʻole a māmā. Hiki ke hoʻoheheʻe ʻia i loko o ka wai (haʻahaʻa ke kaumaha molekala) a me nā mea hoʻoheheʻe organik e like me nā ketones aliphatic a me nā alcohols, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o ka ether a me ka hapa nui o nā hydrocarbons aliphatic. Loaʻa ia ma o ka condensation o ka propylene oxide a me ka propylene glycol ma lalo o ke kaomi kiʻekiʻe a i ʻole ke alo o kahi mea hoʻoulu acidic.

1. Hiki ke hoʻoheheʻe ʻia nā moʻo PPG i nā mea hoʻoheheʻe organik e like me toluene, ethanol, trichloroethylene, a pēlā aku. Hiki ke hoʻoheheʻe ʻia ʻo PPG200, 400, a me 600 i ka wai a he mau waiwai lubricating, soliloquizing, defaming, a me 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 ʻo Poly(propylene glycol) ma ke ʻano he mea anti-foaming agent i nā uhi a me nā aila hydraulic, he mea antifoaming agent i ka hana ʻana i ka rubber synthetic a me ka latex, he refrigerant a me ka coolant no nā wai hoʻoili wela, a he mea hoʻomaikaʻi viscosity.

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

5. Hoʻohana ʻia ʻo Poly(propylene glycol) ma ke ʻano he mea hoʻokuʻu, he mea hoʻoheheʻe, he mea hoʻohui no nā aila synthetic, he mea hoʻohui no nā wai ʻokiʻoki wai-hoʻoheheʻe ʻia, nā aila wili, nā aila hydraulic, nā lubricants wela kiʻekiʻe, a me nā lubricants kūloko a me waho no ka rubber.

6. Loaʻa iā PPG-2000 ~ 8000 ka lubrication maikaʻi loa, anti-foaming, pale wela a me ka hau a me nā waiwai ʻē 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 plastics huʻa polyurethane;

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