Ukumanzisa kwenzeka xa into eqinileyo idibana nolwelo. Indawo yokuqala yokuhlangana kwegesi eqinileyo kunye negesi engamanzi iyanyamalala, kwaye kwenziwa indawo entsha yokuhlangana kwegesi eqinileyo kunye nolwelo. Umzekelo, iifayibha zelaphu zizinto ezinemingxuma enommandla omkhulu womphezulu. Xa isisombululo sisasazeka kwiifayibha, singena kwizikhewu phakathi kweefayibha size sisuse umoya, siguqule indawo yokuqala yokuhlangana kwegesi yomoya ibe yindawo yokuhlangana kwefiber yolwelo.—Le yinkqubo eqhelekileyo yokumanzisa. Okwangoku, isisombululo singena ngaphakathi kwimicu, inkqubo eyaziwa ngokuba kukungena. Izinto ezibangela ukumanzisa nokungena zibizwa ngokuba zii-wetting agents kunye nee-penetration agents ngokwahlukeneyo.
Ukuhlanganiswa kwe-emulsification
Iioyile zinoxinzelelo olukhulu kumphezulu emanzini. Xa ioyile yongezwa emanzini kwaye umxube uxutywe ngamandla, ioyile iyaqhekeka ibe ngamathontsi amancinci ukuze yenze i-emulsion, kodwa umxube uya kwahlulwa ube ngamaleya kwakhona xa ukuxuba kuyeka. Ukuba i-surfactant yongezwa kwaye umxube uxutywe, la maleya awayi kwahlulwa lula ixesha elide emva kokuba ukuxuba kuyekile, oku kukuxuba. Inxalenye ye-hydrophobic yeemolekyuli zeoyile ijikelezwe ngamaqela e-surfactants athanda amanzi, nto leyo edala amandla anomtsalane. Oku kunciphisa amandla afunekayo ukusasaza ioyile emanzini kwaye kufezekisa i-emulsification esebenzayo yeeoyile.
Ngenxa yempembelelo yokuxubha kwezinto ezisetyenziswa kwi-surfactants, amasuntswana eoyile kunye nothuli asuswe kwiindawo eziqinileyo anokuxubha ngokuzinzileyo aze asasazwe kwizisombululo zamanzi, nto leyo ethintela ukuba angaphindi afakwe kwiindawo ezicociweyo aze abangele ukungcola.
Ukusasazeka kubhekisa kwinkqubo apho izinto eziqinileyo ezinganyibilikiyo zisasazwa kwisisombululo njengeesuntswana ezincinci ukuze zenze i-suspension. Izinto ezibangela ukusasazeka kwezinto eziqinileyo nezigcina i-suspensions ezizinzileyo zibizwa ngokuba yi-dispersants. Ngokwenyani, kunzima ukwahlula i-emulsification kwi-dispersion xa ii-oyile eziqinileyo zi-emulsified kwaye zisasazwa kwizisombululo. Ekubeni i-emulsifiers kunye ne-dispersants zihlala ziluhlobo olufanayo lwento, zibizwa ngokuba yi-emulsifier-dispersants kwizicelo ezisebenzayo.
Ukunyibilika kuthetha ukuba izinto ezinyibilikayo zinokunyusa ukunyibilika kwezinto ezinyibilikayo okanye ezinganyibilikiyo emanzini. Umzekelo, ukunyibilika kwebenzene emanzini yi-0.09% ngokomthamo. Emva kokongeza izinto ezinyibilikayo ezifana ne-sodium oleate, ukunyibilika kwebenzene kunokunyuka kuye kwi-10%.
Ukunyibilika kunxulumene kakhulu nee-micelles ezenziwe zii-surfactants emanzini. I-micelle yi-aggregate eyenziweyo xa imixokelelwane ye-hydrocarbon yee-molecules ze-surfactant isondela kwenye kwisisombululo samanzi ngenxa yokusebenzisana kwe-hydrophobic. Ingaphakathi le-micelle ngokuyintloko yi-hydrocarbons ezingamanzi, ngoko ke i-non-polar organic solutes ezinganyibilikiyo emanzini, njenge-benzene kunye ne-mineral oil, zinokunyibilika ngokulula ngaphakathi kwi-micelles. Ukunyibilika kukunyibilika kwezinto ze-lipophilic yi-micelles, ipropati ekhethekileyo yee-surfactants. Isebenza kuphela xa uxinzelelo lwe-surfactant kwisisombululo ludlula uxinzelelo lwe-micelle olubalulekileyo (CMC), oko kukuthi xa inani elikhulu lee-micelles ezinkulu zikhona. Ukongeza, ii-micelles ezinkulu zibonelela ngamandla amakhulu okunyibilika.
Ukunyibilika kwahlukile kwi-emulsification. I-emulsification ivelisa inkqubo ye-multiphase engaqhubekiyo nengazinzanga apho isigaba esinye solwelo sisasazeka emanzini okanye kwesinye isigaba solwelo. Ngokwahlukileyo koko, ukunyibilika kubangela inkqubo yesigaba esinye esilinganayo, esizinzileyo apho isisombululo sokunyibilika kunye nesixhobo esinyibilikayo zikhona kwisigaba esinye. Uhlobo olunye lwe-surfactant lunokuba neempawu zokunyibilikisa kunye nezo zokunyibilikisa, kodwa ukunyibilika kwenzeka kuphela xa uxinzelelo lwayo lungaphezulu koxinzelelo olubalulekileyo lwe-micelle.
Ukuthambisa kunye nokuSmoothing
Xa iimolekyuli ze-surfactant zilungelelana kwicala elithe ngqo kumphezulu welaphu, zinciphisa i-coefficient ye-static friction yamalaphu. Ii-surfactants ezingezizo ii-ionic ezifana ne-linear alkyl polyoxyethylene polyols kunye ne-linear alkyl fatty acid polyoxyethylene ethers, kunye nee-cationic surfactants ezahlukeneyo, zinokunciphisa i-static friction coefficient yamalaphu kwaye ngaloo ndlela zisebenze njenge-fabric softeners. Nangona kunjalo, ii-surfactants ezine-branched alkyl okanye amaqela e-aromatic ziyasilela ukwenza ulungelelwano olucwangcisiweyo lwecala kumphezulu welaphu kwaye ngenxa yoko azifanelekanga ukusetyenziswa njenge-softeners.
