1. I-Chemical Make-up kunye ne-Colloidal Framework
1.1 I-Molecular Architecture yeZinc Stearate
(Ultrafine zinc stearate emulsion)
I-Zinc stearate yisepha yesinyithi eyenziwe yimpendulo ye-stearic acid– i-chain-long-saturated fatty acid (C ₁₇ H ₃₅ COOH)– kunye ne-zinc ions, ebangela ikhompawundi Zn(C ₁₇ H ₃₅ COO)₂.
Isakhiwo sayo se-molecular ibandakanya i-ion ye-zinc ephakathi eququzelelwe 2 imixokelelwane ye-alkyl ye-hydrophobic, ukuphuhlisa ubuntu be-amphiphilic eyenza umsebenzi we-interfacial kuzo zombini iinkqubo zolwelo kunye ne-polymer.
Kuhlobo oluninzi, I-zinc stearate ikhona njengomgubo we-waxy kunye nokuncitshiswa kokunyibilika emanzini kunye nezinyibilikisi ezininzi zendalo, ukukhawulela ukusetyenziswa kwayo okuthe ngqo kwizisombululo ezilinganayo.
Nangona kunjalo, xa isenziwa kanye kwi-emulsion ye-ultrafine, i-bit dimension yehlisiwe ukuya kwi-submicron okanye uluhlu lwe-nanometer (ngokuqhelekileyo 50– 500 nm), ukonyusa kakhulu umgangatho kunye nokusebenza kokusasazwa.
Lo mbuso we-nano-dispersed uphucula ubuntununtunu, ukuba bhetyebhetye, kunye nonxibelelwano neematriki ezingqongileyo, ukuvula ukusebenza okuphezulu kwizicelo zorhwebo.
1.2 Indlela yokuqinisa i-Emulsification kunye noZinziso
Umsebenzi wokulungiselela wesisombululo se-ultrafine zinc stearate ubandakanya i-homogenization ephezulu yokucheba, microfluidization, okanye i-ultrasonication ye-zinc stearate etyhidiweyo emanzini, incediswa zizinto ezenziweyo ezifana ne-nonionic okanye i-anionic emulsifiers.
Ii-surfactants zibhengeza kumphezulu wamathontsi okanye amasuntswana asasazekileyo, ukwehlisa uxinezeleko phakathi kobuso kunye nokunqanda ukuhlangana nge-electrostatic repulsion okanye isithintelo esiqinileyo.
Izinzisi eziqhelekileyo ziquka i-polyoxyethylene sorbitan esters (Ukuqokelelwa phakathi), sodium dodecyl sulfate (SDS), okanye utywala obunxilisayo, ekhethiweyo ngokusekelwe ekusebenzisaneni nesixokelelwano ekujoliswe kuso.
Iindlela zokuguqula inqanaba zingasetyenziselwa ukufikelela kwi-oyile emanzini (O/W) izisombululo ezineqhekeza elincinci lokujikeleza kunye nokuzinza kwe-colloidal ixesha elide.
I-emulsions edalwe ngokufanelekileyo iyaqhubeka nokuzinza kwiinyanga ngaphandle kwe-sedimentation okanye ukuhlukana kwesiteji, ukwenza ukusebenza kakuhle okuthe rhoqo ngexesha lendawo yokugcina kunye nokusetyenziswa.
Ulwelo oluphumela elubala kulwelo olunobisi lunokuba buthathaka lula, imitha, kwaye ibandakanywe kwiinkqubo ezisekelwe emanzini, ukubuyisela i-solvent-borne okanye izithako zomgubo.
