Tšebeliso ea li-surfactants ke efe liphahlong?

Li-surfactantke sehlopha sa metsoako e nang le dibopeho tse ikgethang tsa dimolek'hule tse ka ikamahanyang le di-interface kapa bokahodimo, e leng se fetolang kgatello ya bokahodimo kapa thepa ya di-interfacial haholo. Indastering ya dikobo, di-surfactants di bapala karolo ya bohlokwa ditirisong tse fapaneng, ho kenyeletswa emulsification, kolobisa, ho hasanya, ho tlosa mafoa, ho leka-lekanya, ditlamorao tsa antistatic, le tse ding, ka hona ho ntlafatsa botsitso, tshebetso ya tshebediso, le boleng ba ho qetela ba dikobo.

1. Emulsification​

Likoahelong tse thehiloeng ho emulsion (tse kang likoahelo tse tsamaisoang ke metsi), li-emulsifier lia hlokahala. Li fokotsa tsitsipano ea interfacial pakeng tsa mekhahlelo ea oli le metsi, e leng se nolofalletsang ho thehoa ha li-emulsion tse tsitsitseng ho tsoa likarolong tse sa kopaneng. Li-emulsifier tse tloaelehileng li kenyelletsa li-surfactants tsa anionic (mohlala, sodium dodecylbenzene sulfonate) le li-surfactants tse seng tsa ionic (mohlala, polyoxyethylene ethers).

2. Ho kolobisa le ho hasanya mmala​

Ho hasana ho lekanang ha mebala ka har'a lipente ho ama ka ho toba ho se bonahale, botsitso le ts'ebetso ea 'mala. Lisebelisoa tsa ho kolobisa le ho qhalakanya li fokotsa tsitsipano ea sefahleho lipakeng tsa mebala le li-binder, li khothalletsa ho kolobisa ho tšoanang le ho hasana ho tsitsitseng ha li ntse li thibela ho kopana le ho lula.

3. Taolo ea ho Silafala ha Letlalo le Foam​

Nakong ea tlhahiso le ts'ebeliso, lipekere li atisa ho hlahisa lipululana, e leng se ka sitisang ponahalo le ts'ebetso ea filimi. Li-defoamer (mohlala, tse thehiloeng ho silicone kapa tse thehiloeng ho oli ea diminerale) li sitisa meaho ea foam, li fokotsa ho thehoa ha lipululana le ho netefatsa bokaholimo ba pekere bo boreleli, bo se nang sekoli.

4. Ntlafatso ea Maemo​

Thepa ea ho leka-lekanya ea lipente e khetholla boreledi le ponahalo ea filimi e omisitsoeng. Lisebelisoa tsa ho leka-lekanya li sebetsa ka mekhoa e 'meli ea mantlha:

• Ho fokotsa tsitsipano ea bokaholimo: Ho netefatsa hore ho ata hantle holim'a li-substrate, ho fokotsa liphoso tse kang lekhapetla la lamunu kapa ho khetla.

• Ho fetola mouoane oa solvent: Ho eketsa nako ea phallo, ho lumella lesela ho lekana hantle pele le fola.

5. Tshebetso e sa fetoheng​

Disebedisweng tsa elektroniki, diphuthelong, le mafapheng a mang, dikobo di ka bokella ditjhaja tse sa fetoheng ka lebaka la kgohlano, e leng se bakang dikotsi tsa polokeho. Di-antistatic agents (mohlala, di-cationic surfactants) di monya mongobo o tikolohong ho etsa lera le tsamaisang metsi hodima bokahodimo ba kobo, e leng se thusang ho qhala ha tjhaja le ho fokotsa dikotsi tsa electrostatic.

6. Tšireletso ea ho bolaea likokoana-hloko le li-fungus​

Libakeng tse mongobo, masela a koaheloang a sekametse ho holeng ha likokoana-hloko, e leng se lebisang ho senyeheng ha filimi. Lisebelisoa tse loantšang likokoana-hloko le tse bolaeang li-fungus (mohlala, metsoako ea ammonium ea quaternary) li thibela ho ata ha likokoana-hloko, li eketsa nako ea ho boloka le ho tšoarella ha litšebeletso tsa masela.

7. Ntlafatso ea Khanya le Ntlafatso ea ho Theleha​

Liaparo tse ling li hloka libaka tse benyang haholo kapa tse boreleli (mohlala, thepa ea ka tlung kapa liaparo tsa indasteri). Lisebelisoa tse ntlafatsang khanya le lintho tse thellang (mohlala, boka ba linotši kapa li-silicone) li ntlafatsa khanya ea filimi le ho fokotsa khohlano ea bokaholimo, li eketsa ho hanyetsa ho tsofala le litšobotsi tsa ho ama.

Li-surfactant li phetha mesebetsi e mengata indastering ea ho koahela, ho tloha ho ntlafatseng ts'ebetso ea ts'ebetso ho isa ho phahamiseng thepa ea ho qetela ea filimi, tsohle li sebelisa bokhoni ba tsona bo ikhethang ba taolo ea li-interfacial. Ka tsoelo-pele ea li-surfactant tse mosa tikolohong le tse sebetsang hantle, li-surfactant tse ncha, tse sebetsang hantle le tse nang le chefo e tlase li tla lula e le sepheo sa bohlokoa lipatlisisong tsa theknoloji ea ho koahela nakong e tlang.
