Saina Surfactant Gaosi, Fa'atau, Falegaosimea

Vaega o oloa o le Surfactant , oi matou o kamupani gaosi oloa mai Saina, oi matou o kamupani / fale gaosimea o , , ma Amphoteric Surfactants, oloa faʻatau oloa maualuga maualuga o surfactants R & D ma gaosiga, o loʻo ia i matou le auaunaga sili ona lelei pe a uma ona faʻatau ma lagolago faʻapitoa. Fa'atalitali i la outou galulue fa'atasi!

Surfactant, e taʻua foʻi o le surfactant, o se mea faʻapipiʻi e mafai ona faʻaitiitia ai le faʻalavelave i luga poʻo le va o le va o vai e lua, vai-kesi, poʻo vai-malosi. O le fausaga mole mole o surfactants e amphiphilic: o le tasi pito o se vaega hydrophilic ma le isi pito o se vaega hydrophobic; o le vaega hydrophilic e masani lava o se vaega polar, e pei o le carboxylic acid, sulfonic acid, sulfuric acid, amino po o amine vaega ma ona masima , vaega hydroxyl, vaega amide, eter sootaga, ma isi e mafai foi ona faaaoga e avea polar vaega hydrophilic; ae o vaega hydrophobic e masani ona le polar filifili hydrocarbon, pei o filifili hydrocarbon e sili atu nai lo 8 carbon atoms. Surfactants ua vaevaeina i luga ole ionic surfactants (e aofia ai cationic surfactants, anionic surfactants, amphoteric surfactants), nonionic surfactants, compound surfactants, isi surfactants, ma isi.

Surfactant molelaʻau maua amphiphilicity tulaga ese: tasi pito o se hydrophilic polar vaega, faapuupuuina o le hydrophilic vaega, e lauiloa foi ole oleophobic po ole oleophobic vaega, e pei o le - OH-COOH、-SO3H、-NH2。 Ona o le umi puupuu o nei vaega galue, e ta'ua i nisi taimi o ulu hydrophilic. O le isi pito o se vaega e le o polar lea e lipophilic, fa'apu'upu'u o le lipophilic vaega, e ta'ua foi o le hydrophobic group po'o le hydrophobic group, e pei o le R - (alkyl), Ar - (aryl). Ona o le puupuu o le umi o nei vaega galue, e taʻua i nisi taimi o siʻusiʻu hydrophobic. E lua ituaiga o vaega mole mole o loʻo faʻafeagai atoatoa fausaga ma meatotino o loʻo tu i pito e lua o le mole tutusa ma fesoʻotaʻi i fusi faʻamaʻi, e fausia ai se fausaga asymmetric ma polar, ma faʻapenaina ai lenei mole faʻapitoa i mea uma e lua hydrophilic ma oleophilic, ae le o le aotelega. uiga hydrophilic po'o oleophilic. O le fausaga tulaga ese o surfactants e masani ona taʻua o le "amphiphilic structure", ma o molelaʻau surfactant e masani ona taʻua o "amphiphilic molecules".
