Li-surfactants ke sehlopha sa lik'hemik'hale tse sebelisoang haholo bophelong ba letsatsi le letsatsi le tlhahiso ea indasteri.

Li na le litšobotsi tsa ho fokotsa tsitsipano ea metsi holim'a metsi le ho ntlafatsa bokhoni ba ho sebelisana pakeng tsa mokelikeli le tiileng kapa khase.

TMAO, Trimethylamine oxide, dihydrate, CAS NO.: 62637-93-8, ke ntho e sebetsang ka holim'a metsi le li-surfactants, li ka sebelisoa ho hlatsoa lisebelisoa.

Li-oxidants tse fokolang tsa TMAO

Trimethylamine oxide, e le oxidant e fokolang, e sebelisoa ho lik'hemik'hale tsa lik'hemik'hale bakeng sa motsoako oa aldehydes, oxidation ea organic boranes, le ho lokolloa ha li-ligands ho tloha metsoako ea tšepe ea carbonyl.

•  Sebopeho sa li-surfactants

Li-surfactants li arotsoe likarolo tse peli: lihlopha tsa hydrophilic le lihlopha tsa hydrophobic.Sehlopha sa hydrophilic ke sehlopha sa polar se entsoeng ka liathomo tse kang oksijene, naetrojene kapa sebabole tse nang le hydrophilic.Lihlopha tsa Hydrophobic ke likarolo tsa hydrophobic, hangata li entsoe ka lihlopha tse seng tsa polar joalo ka lihlopha tse telele tsa alkyl kapa tse nkhang hamonate.Sebopeho sena se lumella li-surfactants ho sebelisana le metsi le lintho tsa hydrophobic tse kang oli.

•  Mokhoa oa ts'ebetso oa li-surfactants

Li-surfactants li etsa lera la molek'hule holim'a metsi, le tsejoang e le adsorption layer.Ho thehoa ha lesela la adsorption ho bakoa ke ho thehoa ha likamano tsa hydrogen pakeng tsa lihlopha tsa hydrophilic tsa limolek'hule tsa surfactant le limolek'hule tsa metsi, ha lihlopha tsa hydrophobic li sebelisana le limolek'hule tsa moea kapa tsa oli.Lera lena la adsorption le ka fokotsa tsitsipano ea metsi ka holim'a metsi, la etsa hore ho be bonolo hore mokelikeli o kolobise bokaholimo bo tiileng.

Li-surfactants le tsona li ka theha meaho ea micelle.Ha bongata ba surfactant bo feta mahloriso a bohlokoa a micelle, limolek'hule tsa surfactant li tla ipokella ka botsona ho etsa li-micelles.Li-micelles ke libopeho tse nyenyane tse chitja tse entsoeng ke lihlopha tsa hydrophilic tse shebaneng le karolo ea metsi le lihlopha tsa hydrophobic tse shebileng ka hare.Li-micelles li ka kenyelletsa lintho tsa hydrophobic tse kang oli le ho li qhalakanya karolong ea metsi, kahoo li finyella liphello tsa emulsifying, qhalakanya le ho qhibiliha.

• Libaka tsa ts'ebeliso ea li-surfactants

1. Moemeli oa ho hloekisa: Li-surfactants ke karolo e ka sehloohong ea lisebelisoa tsa ho hloekisa, tse ka fokotsang tsitsipano ea metsi holim'a metsi, e leng ho nolofalletsang metsi ho koloba le ho kenella, ka hona ho ntlafatsa phello ea ho hloekisa.Ka mohlala, lisebelisoa tsa ho hloekisa tse kang sesepa sa ho hlatsoa liaparo le sesepa sa ho hlatsoa lijana kaofela li na le li-surfactants.

2. Lihlahisoa tsa tlhokomelo ea botho: Li-surfactants li ka etsa lihlahisoa tsa tlhokomelo ea botho tse kang shampoo le gel ea ho hlatsoa li hlahisa foam e ngata, e fanang ka liphello tse ntle tsa ho hloekisa le ho hloekisa.

3. Litlolo: Litlolo li phetha karolo ea bohlokoa ho etseng litlolo, ho hasanya le ho tsitsisa litlolo.Ka mohlala, li-emulsifiers le dispersants ka lotion, sefahleho sa tranelate le litlolo ke li-surfactants.

4. Chefo e bolaeang likokoanyana le lisebelisoa tsa temo: Lisebelisoa li ka ntlafatsa ho koloba le ho kenella ha chefo e bolaeang likokoanyana, ho ntlafatsa matla a tsona a ho kenella le ho kenella, le ho ntlafatsa katleho ea chefo e bolaeang likokoanyana.

5. Indasteri ea peterole le ea lik'hemik'hale: Li-surfactants li phetha karolo ea bohlokoa lits'ebetsong tse kang ho ntšoa ha oli, ente ea metsi sebakeng sa oli, le karohano ea metsi a oli.Ho feta moo, li-surfactants li sebelisoa haholo ho lubricant, rust inhibitors, emulsifiers le mafapha a mang.

Kakaretso:

Li-surfactants ke mofuta oa lintho tsa lik'hemik'hale tse nang le bokhoni ba ho fokotsa tsitsipano ea metsi holim'a metsi le ho ntlafatsa tšebelisano lipakeng tsa mokelikeli le tse tiileng kapa tsa khase.Sebopeho sa eona se entsoe ka lihlopha tsa hydrophilic le hydrophobic, tse ka etsang likarolo tsa adsorption le mehaho ea micelle.Li-surfactants li sebelisoa haholo ho hloekisa, lihlahisoa tsa tlhokomelo ea motho, litlolo, chefo e bolaeang likokoanyana le li-additives tsa temo, liindasteri tsa petroleum le lik'hemik'hale, le masimo a mang.Ka ho utloisisa melao-motheo ea lik'hemik'hale tsa li-surfactants, re ka utloisisa hamolemo litšebeliso tsa tsona le mekhoa ea ts'ebetso likarolong tse fapaneng.
