ʻO ka paʻa kalapona ʻo Methyl silicon ka paʻa paʻa loa; ʻO ka heleʻana o ka silicone methyl hāʻawi i kaʻaila silicone i nā waiwai kūikawā; ʻO nā ʻano ʻaila silicone a pau nā derivatives o ka ʻaila methyl silicone; Kapa ʻia ka ʻaila silicone derivative ma hope o nā hui ʻē aʻe ma mua o nā hui methyl.

Hoʻokaʻawale ʻaila silika

ʻO ka ʻaila silicone inert:i ka hoʻohana maʻamau, ʻaʻole i komo i nā hopena kemika, ʻoi aku ka nui o ka hoʻohana ʻana i nā waiwai kino o ka ʻaila silicone, ma mua o nā waiwai kemika. E like me: methyl silicone oil, phenyl silicone oil, polyether silicone oil, long alkyl silicone oil, trifluoropropyl silicone oil, ethyl silicone oil, etc.

ʻO ka aila silicone reactive: loaʻa kahi pūʻulu reactive maopopo, pili pinepine i nā hopena kemika i ka hoʻohana ʻana.
E like me: hydroxysilicone oil, vinyl silicone oil, hydrogen silicone oil, amino silicone oil, sulfhydryl silicone oil. ʻO ka ʻaila silikon kahi ʻano ʻaila ʻaila kūikawā me ka paʻa kalapona silika a me ka paʻa kilika silika. Hāʻawi ka Silicon methyl i ka hana ma luna, hydrophobic, a me ka hoʻokuʻu; Hāʻawi ka hana silika i ke kūpaʻa (inert) a me nā waiwai uila maikaʻi loa.

Hoʻokomo ʻaila silicone maʻamau
ʻaila methylsilicone
Wehewehe:ʻO nā pūʻulu organik a pau i loko o ka hoʻolālā molekala he pūʻulu methyl.
Nā hiʻohiʻona:maikaʻi paʻa wela; dielectric maikaʻi; hydrophobicity; viscosity a me ka hōʻino. ʻO ka mea kālepa nui loa, ka aila silicone (201, DC200, KF 96, TSF451).
Kaʻina hoʻomākaukau:E hoʻomākaukau me ka hoʻohana ʻana i ka pane kaulike.
ʻO ke ʻano o ke ʻano:hoʻohana pinepine ʻia ka viscosity e hōʻike i ka polymerization o ka ʻaila silicone, hoʻohana ʻia ka viscosity e ʻike i nā huahana, ka hoʻomau mau ʻana o ka viscosity methyl silicone oil ma lalo o 50mPa.s.
Mea hoʻomākaukau:50mPa.s Kaʻaila methylsilicone kālepa, hexamethyldisiloxane (poʻo luna), macroporous acid cationic resin.
ʻōnaehana uila.
Mea hoʻomākaukau:he kolamu hopena i hoʻopiha ʻia me ka resin, kahi ʻōnaehana uila ʻāmā.
Kaʻina pōkole:E hoʻohui i ka ʻaila methyl silicone a me ka mea hoʻokaʻawale i ka hoʻohālikelike ʻana ma o ke kolamu hopena, a uila e kiʻi i ka ʻaila silicone paʻa.

loaʻa ka ʻaila hydrogen silicone.
