Izithasiselo Zokubulala Izinambuzane ziyizinto ezisizayo ezingeziwe ngesikhathi sokucubungula noma ukusetshenziswa kwezakhi zokubulala izinambuzane ukuthuthukisa izakhiwo zazo ze-physicochemical, ezaziwa nangokuthi izithasiselo zokubulala izinambuzane. Ngenkathi izithasiselo ngokwazo ngokuvamile zinomsebenzi omncane noma zingenawo nhlobo umsebenzi webhayoloji, zingathonya kakhulu ukusebenza kahle kokulawulwa kwezinambuzane. Ngokusetshenziswa kabanzi kanye nokuthuthukiswa kwezithasiselo zokubulala izinambuzane, ukuhlukahluka kwazo kuqhubekile nokukhula, okwenza ukukhethwa kwesithasiselo esifanele kube yinselele yesibili enkulu kubalimi ngemuva kokukhetha isithasiselo sokubulala izinambuzane uqobo.
1.Izithako Ezisiza Ekusabalaleni Kwezithako Ezisebenzayo
· Abagcwalisi kanye nabathwali
Lezi yizinto eziqinile zamaminerali, ezisekelwe ezitshalweni, noma ezenziwe ngezinto ezingeziwe ngesikhathi sokucubungula amafomula ezibulala izinambuzane eziqinile ukulungisa ukuhlushwa komkhiqizo wokugcina noma ukuthuthukisa isimo sawo somzimba. Izithako zokugcwalisa zisetshenziselwa ukuncibilikisa isithako esisebenzayo nokuthuthukisa ukusabalala kwawo, kuyilapho izithwali nazo zisebenza ekumunceni noma ekuthwaleni izingxenye ezisebenzayo. Izibonelo ezivamile zifaka ubumba, umhlaba we-diatomaceous, i-kaolin, kanye nobumba lobumba.
Ama-filler ngokuvamile ayizinto ezingaphili ngendlela engathathi hlangothi njengobumba, ubumba lwezitsha, i-kaolin, umhlaba we-diatomaceous, i-pyrophyllite, kanye ne-talcum powder. Imisebenzi yawo eyinhloko ukuncibilikisa isithako esisebenzayo nokusimunca. Asetshenziswa kakhulu ekukhiqizeni impushana, impushana ezimanzi, ama-granule, kanye nama-granule angahlakazeka ngamanzi. Inhlanganisela ethandwayo njengamanje yezibulala-zinambuzane nomanyolo (noma “umanyolo odakiwe”) basebenzisa umanyolo njengabathwali bezibulala-zinambuzane, behlanganisa lokhu okubili ukuze kufezwe ukusetshenziswa okuhlangene.
Abathwali hhayi nje kuphela ukuncibilikisa isithako esisebenzayo kodwa futhi kusiza ukusimunca, kudlala indima ebalulekile ekuqineni kokwakheka.
·Izinyibilikisi
Izinto eziphilayo ezisetshenziselwa ukuncibilikisa nokunciphisa izithako ezisebenzayo zezibulala-zinambuzane, okwenza kube lula ukucubungula nokusetshenziswa kwazo. Izinyibilikisi ezivamile zifaka i-xylene, i-toluene, i-benzene, i-methanol, kanye ne-petroleum ether. Zisetshenziswa kakhulu ekwakhiweni kwezinto ezixubile ezingaxubeki (EC). Izidingo ezibalulekile zifaka phakathi amandla aqinile okuncibilikisa, ubuthi obuphansi, iphuzu eliphezulu lokukhanya, ukungashi, izindleko eziphansi, kanye nokutholakala kabanzi.
·Ama-Emulsifier
Ama-surfactant azinzisa ukusabalala koketshezi olulodwa olungaxubeki (isb. uwoyela) luye kolunye (isb., amanzi) njengamaconsi amancane, akha i-emulsion engacacile noma engacacile. Lawa abizwa ngokuthi ama-emulsifier. Izibonelo ezivamile zifaka phakathi ama-ester noma ama-ether asekelwe ku-polyoxyethylene (isb., uwoyela we-castor polyoxyethylene ether, i-alkylphenol polyethylene ether), uwoyela obomvu waseTurkey, kanye ne-sodium dilaurate diglyceride. Asetshenziswa kabanzi kuma-concentrates angaxubeki, ama-formulations e-water-emulsion, kanye nama-microemulsion.
·Izisabalalisi
Ama-surfactant asetshenziswa ekwakhiweni kwezibulala-zinambuzane ukuvimbela ukuhlangana kwezinhlayiya eziqinile ezinhlelweni zokuhlakazeka koketshezi oluqinile, okuqinisekisa ukumiswa kwazo okufanayo isikhathi eside koketshezi. Izibonelo zifaka phakathi i-sodium lignosulfonate kanye ne-NNO. Asetshenziswa kakhulu ekukhiqizweni kwama-powder angemanzi, ama-granule ahlakazeka ngamanzi, kanye nama-suspension amanzi.
