Ka lebaka la ts'ebetso e ntle ea sebopeho sa organicoli ea silicone, e sebelisoa ka ho pharaletseng ho qeta ho nolofatsa masela.Mefuta ea eona e ka sehloohong ke: moloko oa pele oa oli ea silicone ea hydroxyl le oli ea silicone ea hydrogen, moloko oa bobeli oa oli ea amino silicone, ho isa molokong oa boraro oli e mengata ea silicone block.Ha tlhoko ea batho ea ho sebetsana le eona e ntlafetse, oli ea silicone ea organic e bile le ntlafatso ea mashome a lilemo.
1.Hydroxyl silicone oli
Sebopeho se seholo sa oli ea silicone ea hydroxyl ke polymer e nang le mela e nang le lihlopha tsa hydroxyl lipheletsong tse peli le silica silicon e le ketane e kholo.Mokhoa o tloaelehileng oa ho kopanya ke o entsoeng ka hydrolyzing polycondensation ea dimethyl dichlorosilane.Ka lebaka la matla a eona a tlaase, polarity e fokolang le adsorption e fokolang holim'a substrate, tšebeliso e tloaelehileng ea oli ea silicone ea hydroxyl e hloka boima bo phahameng ba limolek'hule ho ba le phello e ntle ea kopo.Ka hona, ka kakaretso oli ea silicone ea hydroxyl e sebelisoa e le ho qetelanolofatsake polima e nang le boima bo phahameng ba molek'hule.Ho na le tšitiso ea hore joalo ka oli ea silicone, ka lebaka la matla a tlase a holim'a metsi le phepelo ea metsi e futsanehileng haholo, karolo e phahameng ea li-emulsifiers le mochini oa ho kuta le o qhalakantsoeng o nang le phallo e phahameng e hlokahalang ho e etsa emulsify le ho e hasanya ka har'a li-microemulsions tse betere.Empa ho sa tsotellehe sena, botsitso ba eona ba botsofali bo ntse bo fokola.Ho ntse ho tla ba le ts'ebetso ea emulsion stratification kamora nako e telele e behiloe.
2.Oli ea silicone ea hydrogen
Sebopeho se ka sehloohong sa oli ea silicone ea hydrogen ke polysiloxane e nang le silicon-hydrogen bond e arolelitsoeng ka ho lekana ka lehlakoreng la ketane ea oksijene ea silicon.Mekhoa e tloaelehileng ea ho kopanya e kenyelletsa hydrolytic polycondensation ea methyl hydrodichlorosilane le polymerization e bulang mehele ea 'mele ea mehele ea hydrosiloxane.Hobane botsitso ba bond ea silicon-hydrogen bo futsanehile, ho bonolo ho dehydrogenate 'me ka hona ho bonolo ho bokelloa ka lihlopha tsa polar ka thepa ea masela.Kahoo e na le thepa e ntle ea adsorptive.E na le ts'ebetso e ntle ea ts'ebeliso ho likhoele tsa cellulose le likhoele tsa protheine, ha e na le phello e mpe ho likhoele tsa lik'hemik'hale.E ts'oanang le oli ea silicone ea hydroxyl, ts'ebetso ea eona ea emulsifying ha e ntle mme botsitso ba eona ha bo bobe.Haeba lihlahisoa tsa haedrojene li phahame haholo nakong ea kopo, ho bonolo ho lebisa ho hore lihlahisoa tsa hydrogen tse mebala-bala li phahame haholo, tse kotsi ho tikoloho ea mocheso o phahameng ha o beha.
3.Oli ea silicone ea amino
Sebopeho se seholo saoli ea amino silicone isa polysiloxane e nang le sehlopha sa amino ka mahlakoreng ka mor'a polymerization ka ho eketsa amino silane coupling agent.Bonolo le dispersibility ea metsi ea polysiloxane li ntlafala haholo ka lebaka la ho ba le papatso e ntle le bokhoni bo tlamang ba sehlopha sa amino ho lesela le polarity e ntle.Haholo-holo masela a masela a cellulose, e na le phello e ntle haholo ea ts'ebeliso.Ka ho fetola boleng ba ammonia, mofuta oa amino silane coupling agent le boima ba molek'hule oa oli ea amino silicone e ka fetoloa.Seo se ka lokisa litlamorao tse ngata tsa kopo.Leha ho le joalo, hobane ketane ea eona e ka sehloohong e ntse e le sebopeho sa siloxane, kahoo e hloka moemeli oa emulsifying ho fihlela phello e ntle ea emulsifying.Ka nako e ts'oanang, hobane ts'ebetso ea amino ea oli ea silicone ea amino e phahame mme hape e ka lehlakoreng la lesapo.Kahoo ho thata ho e tlosa lesela ka mor'a ho adsorption.Seo se tla ba thata ho se tlosa ts'ebetsong ea ho daea le ho qeta ha ho hlokahala ho fetola 'mala, ho felisa wrinkles kapa matheba a silicone.Hape ho hanyetsa metsi a thata kapa metsi a alkali ea emulsion ea eona ka bobeli ba fokola.
4.Thibela oli ea silicone
Sebopeho se ka sehloohong sa oli ea block silicone ke hore ka har'a ketane e kholo ea polysiloxane e kenngoa, e entsoe le ho etsoa polymerized ka likarolo tse ling tsa ketane ea hydrophilic polyether.Ka mokhoa oa ho thibela, ho theha le ho polymerizing ka karolo ea ketane ea amino, e ntlafatsang ts'ebetso ea hydrophilic le thepa ea emulsifying ea siloxane.Ka ho fetola karo-karolelano, mefuta le boima ba limolek'hule tsa likarolo tse tharo tsa ketane, ho ka lokisetsa lihlahisoa tse ngata.Bakeng sa phepelo ea eona e ntle ea hydrophilic, e loketse haholo bakeng sa ho nolofatsa ho phethela likhoele tsa lik'hemik'hale, ka ts'ebetso e ntle ea ho fetola mmala le ho tlosa.Hobane sehlopha sa amino ke sa ammonia, tertiary ammonia esita le quaternary ammonia, ha ho bonolo ho ba mosehla.Hape ke sesebelisoa se bonolo se tsebahalang liphuputsong tsa phetoho matsatsing ana.
