Tuam Tshoj Surfactant Chaw tsim tshuaj paus, tsum, Hoobkas

Yam khoom ntawm Surfactant, peb yog cov chaw tsim khoom tshwj xeeb los ntawm Tuam Tshoj, peb yog cov chaw muag khoom / lub Hoobkas ntawm , , thiab Amphoteric Surfactants, lag luam wholesale cov khoom zoo ntawm surfactants R & D thiab kev tsim khoom, peb muaj cov kev pabcuam zoo tshaj plaws tom qab muag thiab kev txhawb nqa. tos ntsoov rau koj txoj kev koom tes!

Surfactant, tseem hu ua surfactant, yog ib qho kev sib xyaw ua ke uas tuaj yeem txo qhov nro ntawm lub ntsej muag lossis kev sib tshuam ntawm ob lub kua, kua-gas, lossis kua-kua. Cov qauv molecular ntawm surfactants yog amphiphilic: ib kawg yog ib pawg hydrophilic thiab lwm kawg yog ib pawg hydrophobic; pawg hydrophilic feem ntau yog ib pawg polar, xws li carboxylic acid, sulfonic acid, sulfuric acid, amino lossis amine pawg thiab nws cov ntsev, hydroxyl pawg, amide pawg, ether bonds, thiab lwm yam kuj tuaj yeem siv los ua pawg polar hydrophilic; thaum cov pab pawg hydrophobic feem ntau tsis yog-polar hydrocarbon chains, xws li hydrocarbon chains nrog ntau dua 8 carbon atoms. Surfactants muab faib ua ionic surfactants (xws li cationic surfactants, anionic surfactants, amphoteric surfactants), nonionic surfactants, compound surfactants, lwm yam surfactants, thiab lwm yam.

Surfactant molecules muaj qhov tshwj xeeb amphiphilicity: ib kawg yog pawg hydrophilic polar, abbreviated li hydrophilic pawg, los yog oleophobic lossis oleophobic pawg, xws li - OH- COOH, - SO3H, - NH2. lawv qee zaum hu ua hydrophilic hau. Lwm qhov kawg yog ib pawg tsis-polar uas yog lipophilic, abbreviated li lipophilic pawg, tseem hu ua hydrophobic pawg lossis hydrophobic pawg, xws li R - (alkyl), Ar - (aryl). Vim qhov luv luv ntawm cov pab pawg ua haujlwm no, qee zaum lawv raug hu ua hydrophobic tails. Ob hom molecular pawg nrog cov qauv sib txawv kiag li thiab cov khoom muaj nyob rau ntawm ob qhov kawg ntawm tib lub molecule thiab txuas nrog cov khoom siv tshuaj lom neeg, tsim cov qauv asymmetric thiab polar, yog li muab qhov tshwj xeeb molecule no nrog ob qho tib si hydrophilic thiab oleophilic zog, tab sis tsis yog tag nrho. Cov yam ntxwv ntawm hydrophilic lossis oleophilic. Cov qauv tshwj xeeb ntawm surfactants feem ntau hu ua "amphiphilic qauv", thiab surfactant molecules yog li feem ntau hu ua "amphiphilic molecules".
