Kwizicelo zezibulali-zinambuzane, ukusetyenziswa ngokuthe ngqo kwesithako esisebenzayo kunqabile. Uninzi lwezi fomyula lubandakanya ukuxuba izibulali-zinambuzane nezincedisi kunye nezinyibilikisi ukuphucula ukusebenza kakuhle nokunciphisa iindleko. Izithako ezisetyenziswayo zizinto ezincedisayo eziphambili eziphucula ukusebenza kwezibulali-zinambuzane ngelixa zinciphisa iindleko, ngokuyintloko ngokusebenzisa i-emulsification, i-foaming/defoaming, i-dispersion, kunye ne-wetting effects. Ukusetyenziswa kwazo ngokubanzi kwi-formulations zezibulali-zinambuzane kubhaliwe kakuhle.
Ii-surfactants ziphucula uxinzelelo phakathi kwezinto ezikwi-emulsions, nto leyo eyenza i-uniform kunye neenkqubo zokusasazwa ezizinzileyo. Ulwakhiwo lwazo oluhlala emanzini abandayo—oludibanisa amaqela athanda amanzi kunye namaqela athanda amafutha—luvumela ukufunxwa kwamanzi kwi-oyile. Oku kunciphisa uxinzelelo lwe-interfacial kwaye kunciphisa amandla afunekayo ekwakhiweni kwe-emulsion, ngaloo ndlela kuphucula uzinzo.
Ukuchitha izithako ezisebenzayo zezibulali-zinambuzane emanzini njengoko amasuntswana amancinci evelisa ukusebenza okuphezulu xa kuthelekiswa nezinye iindlela. Ii-emulsifiers zichaphazela ngokuthe ngqo ukuzinza kwee-emulsion zezibulali-zinambuzane, nto leyo egqiba ukusebenza kwazo.
Uzinzo luyahluka ngokobungakanani beconsi:
● Iinxalenye <0.05 μm: Zinyibilikisiwe emanzini, zizinzile kakhulu.
● Amasuntswana angama-0.05–1 μm: Anyibilikiswe kakhulu, azinzile.
● Amasuntswana 1–10 μm: Ukuchitheka kwenkunkuma okanye ukuna kwemvula ngokuhamba kwexesha.
● Amasuntswana >10 μm: Axhonywe ngokubonakalayo, angazinzanga kakhulu.
Njengoko izakhiwo zezibulali-zinambuzane zitshintsha, ii-organophosphates ezinetyhefu kakhulu ziyathatyathelwa indawo zezinye iindlela ezikhuselekileyo, ezisebenzayo nezingenatyhefu kangako. Ii-Heterocyclic compounds—ezifana ne-pyridine, i-pyrimidine, i-pyrazole, i-thiazole, kunye ne-triazole derivatives—zihlala zikhona njengeziqinileyo ezinokunyibilika okuncinci kwizinyibilikisi eziqhelekileyo. Oku kufuna ii-emulsifiers ezintsha, ezisebenzayo kakhulu, nezingenatyhefu kangako ukuze zenziwe.
I-China, inkokheli yehlabathi kwimveliso nokusetyenziswa kwezibulali-zinambuzane, ibike iitoni ezizigidi eziyi-2.083 zemveliso yezibulali-zinambuzane ezikumgangatho wobugcisa ngo-2018. Ukwanda kolwazi ngokusingqongileyo kuye kwabangela imfuno yemixube ekumgangatho ophezulu. Ngenxa yoko, uphando kunye nokusetyenziswa kwezibulali-zinambuzane ezinobuhlobo nokusingqongileyo nezisebenza kakuhle kuye kwaduma. Izibulali-zinambuzane ezikumgangatho ophezulu, njengezinto ezibalulekileyo, zidlala indima ebalulekileyo ekuphuculeni ubuchwepheshe bezibulali-zinambuzane obuzinzileyo.
