Kina Mea hoʻokuʻu Mea Hana, Mea Hoʻolako, Hale Hana

ʻO nā ʻāpana huahana o Surfactant, mākou nā mea hana kūikawā mai Kina, nā mea hoʻolako / hale hana o , , a me Amphoteric Surfactants, nā huahana kiʻekiʻe kiʻekiʻe o nā surfactants R & D a me ka hana ʻana, loaʻa iā mākou ka lawelawe ma hope o ke kūʻai aku a me ke kākoʻo ʻenehana. E kakali i kāu hui!

ʻO Surfactant, ʻike ʻia hoʻi ʻo surfactant, he mea hoʻohui e hiki ke hōʻemi nui i ka haʻalulu o ka ʻili a i ʻole ka hoʻopaʻapaʻa interfacial ma waena o ʻelua wai, wai-gas, a i ʻole wai-paʻa. He amphiphilic ka molecular structure o surfactants: he hui hydrophilic kekahi hopena a he hui hydrophobic kekahi; ʻO ka hui hydrophilic he hui polar pinepine, e like me ka carboxylic acid, sulfonic acid, sulfuric acid, amino a amine pūʻulu a me kāna mau paʻakai , nā hui hydroxyl, nā hui amide, nā paʻa ether, a me nā mea ʻē aʻe hiki ke hoʻohana ʻia e like me nā pūʻulu hydrophilic polar; ʻoiai nā pūʻulu hydrophobic he mau kaulahao hydrocarbon non-polar, e like me nā kaulahao hydrocarbon me ka ʻoi aku o 8 mau kalapona kalapona. Hoʻokaʻawale ʻia nā surfactants i loko o nā surfactants ionic (me nā cationic surfactants, anionic surfactants, amphoteric surfactants), nonionic surfactants, compound surfactants, nā surfactants ʻē aʻe, etc.

Loaʻa i nā molekala surfactant ka amphiphilicity kūʻokoʻa: ʻo kekahi hopena he pūʻulu polar hydrophilic, i hoʻopau ʻia he pūʻulu hydrophilic, ʻike ʻia hoʻi he hui oleophobic a oleophobic paha, e like me - OH- COOH、-SO3H、-NH2。 Ma muli o ka pōkole o kēia mau pūʻulu hana, Ua kapa ʻia lākou i kekahi manawa he poʻo hydrophilic. ʻO ka hopena ʻē aʻe he pūʻulu polar ʻole he lipophilic, i hoʻopau ʻia he pūʻulu lipophilic, ʻike ʻia hoʻi he hui hydrophobic a i ʻole hui hydrophobic, e like me R - (alkyl), Ar - (aryl). Ma muli o ka pōkole o kēia mau pūʻulu hana, ua kapa ʻia lākou i kekahi manawa he huelo hydrophobic. Aia nā ʻano ʻelua o nā pūʻulu molekula me nā ʻano like ʻole a me nā waiwai ma nā ʻaoʻao ʻelua o ka mole hoʻokahi a hoʻopili ʻia e nā paʻa kemika, e hana ana i kahi ʻano asymmetric a me ka polar, no laila e hāʻawi ana i kēia mole kūikawā me nā waiwai hydrophilic a me ka oleophilic, akā ʻaʻole ka holoʻokoʻa. hydrophilic a oleophilic ano. ʻO ke ʻano kūʻokoʻa o nā surfactants i kapa ʻia ʻo "amphiphilic structure", a no laila ua kapa pinepine ʻia nā molekala surfactant he "amphiphilic molecules".
