I-China I-surfactant Umkhiqizi, Umhlinzeki, Imboni

Izigaba zomkhiqizo we- I-Surfactant , singabakhiqizi abakhethekile abavela e-China, singabahlinzeki/ifekthri ye-Surfactant. , , kanye nama-Amphoteric Surfactants, imikhiqizo yekhwalithi ephezulu yama-surfactants e-R & D nokukhiqiza, sinesevisi ephelele ngemva kokuthengisa nokusekelwa kobuchwepheshe. Bheka phambili ukubambisana kwakho!

I-Surfactant, eyaziwa nangokuthi i-surfactant, iyinhlanganisela enganciphisa kakhulu ukungezwani kwendawo noma ukungezwani phakathi koketshezi olubili, i-liquid-gas, noma i-liquid-solid. Isakhiwo se-molecular of surfactants siyi-amphiphilic: isiphetho esisodwa siyiqembu le-hydrophilic kanti elinye liyiqembu le-hydrophobic; iqembu le-hydrophilic ngokuvamile liyiqembu le-polar, njenge-carboxylic acid, i-sulfonic acid, i-sulfuric acid, i-amino noma i-amine iqembu kanye nosawoti walo , amaqembu e-hydroxyl, amaqembu e-amide, izibopho ze-ether, njll. kuyilapho amaqembu e-hydrophobic ngokuvamile engamaketanga e-hydrocarbon angewona e-polar, njengamaketanga e-hydrocarbon anama-athomu e-carbon angaphezu kuka-8. Ama-surfactants ahlukaniswe ngama-ionic surfactants (okubandakanya ama-cationic surfactants, ama-anionic surfactants, ama-amphoteric surfactants), ama-nonionic surfactants, ama-surfactants ayinhlanganisela, amanye ama-surfactants, njll.

Ama-molecule e-surfactant ane-amphiphilicity eyingqayizivele: umkhawulo owodwa yiqembu le-hydrophilic polar, elifushanisiwe njengeqembu le-hydrophilic, elaziwa nangokuthi iqembu le-oleophobic noma i-oleophobic, njengokuthi - OH- COOH, -SO3H, -NH2. Ngenxa yobude obufushane bala maqembu asebenzayo, ngezinye izikhathi zibizwa ngokuthi amakhanda e-hydrophilic. Esinye isiphetho yiqembu elingelona i-polar eliyi-lipophilic, elifushanisiwe njengeqembu le-lipophilic, elaziwa nangokuthi iqembu le-hydrophobic noma iqembu le-hydrophobic, njenge-R - (alkyl), Ar - (aryl). Ngenxa yobude obufushane bala maqembu asebenzayo, ngezinye izikhathi abizwa ngokuthi imisila ye-hydrophobic. Izinhlobo ezimbili zamaqembu amangqamuzana anezakhiwo nezakhiwo ezihluke ngokuphelele zitholakala emikhawulweni emibili ye-molecule efanayo futhi exhunywe ngamabhondi amakhemikhali, akha isakhiwo se-asymmetric ne-polar, ngaleyo ndlela enikeza le molecule ekhethekile kokubili izakhiwo ze-hydrophilic ne-oleophilic, kodwa hhayi jikelele. izici ze-hydrophilic noma i-oleophilic. Isakhiwo esiyingqayizivele sama-surfactants sivame ukubizwa ngokuthi "isakhiwo se-amphiphilic", futhi ama-molecule e-surfactant ngakho-ke avame ukubizwa ngokuthi "ama-amphiphilic molecules".
