Ama-Pesticide Adjuvants yizinto ezisizayo ezingezwe ngesikhathi sokucutshungulwa noma kusetshenziswa ukwakheka kwezibulala-zinambuzane ukuze kuthuthukiswe izakhiwo zazo ze-physicochemical, ezaziwa nangokuthi izithasiselo zezibulala-zinambuzane. Nakuba ama-adjuvant ngokwawo ngokuvamile engenawo umsebenzi webhayoloji, angaba nomthelela omkhulu ekusebenzeni kokulawula izinambuzane. Ngokusetshenziswa kabanzi kanye nokuthuthukiswa kwezithasiselo zezibulala-zinambuzane, ukuhlukahluka kwazo kuye kwaqhubeka kwanda, okwenza ukukhethwa kwe-adjuvant efanele kube inselele yesibili enkulu kubalimi ngemva kokukhetha isibulala-zinambuzane ngokwaso.
1.Ama-Adjuvants Asiza Ekuhlakazweni Kwezithako Ezisebenzayo.
·Izigcwalisi nezithwali.
Lawa amaminerali aqinile angasebenzi, asekelwe esitshalweni, noma izinto zokwenziwa ezengezwe ngesikhathi sokucutshungulwa kokwakheka kwesibulala-zinambuzane esiqinile ukuze kulungiswe ukugcwala komkhiqizo wokugcina noma ukuthuthukisa isimo sawo somzimba. Izigcwalisi zisetshenziselwa ukuhlambulula isithako esisebenzayo futhi kuthuthukiswe ukuhlakazwa kwayo, kuyilapho abathwali bephinde basebenze ukukhangisa noma ukuthwala izinto ezisebenzayo. Izibonelo ezijwayelekile zifaka ubumba, umhlaba we-diatomaceous, i-kaolin, nobumba lobumba.
Izigcwalisi ngokuvamile ziyizinto ezingathathi hlangothi ezifana nobumba, ubumba lobumba, i-kaolin, umhlaba we-diatomaceous, i-pyrophyllite, nempushana ye-talcum. Imisebenzi yabo eyinhloko ukuhlambulula isithako esisebenzayo nokusikhangisa. Asetshenziswa kakhulu ekukhiqizeni izimpushana, izimpushana ezimanzi, ama-granules, nama-granules ahlakazeka emanzini. Izinhlanganisela zomanyolo nezibulala-zinambuzane ezidumile njengamanje (noma “umanyolo owenziwe ngemithi”) sebenzisa umanyolo njengabathwali bezibulala-zinambuzane, ukuhlanganisa kokubili ukuze kuzuzwe ukusetshenziswa okuhlangene.
.Abathwali akugcini nje ngokuncibilikisa isithako esisebenzayo kodwa futhi sisize ukusikhangisa, okudlala indima ebalulekile ekuzinzeni kokwakheka.
·Izincibilikisi.
Izinto eziphilayo ezisetshenziselwa ukuncibilikisa kanye nokunciphisa izithako ezisebenzayo zezibulala-zinambuzane, kube lula ukucubungula nokusetshenziswa kwazo. Izincibilikisi ezivamile zifaka i-xylene, i-toluene, i-benzene, i-methanol, ne-petroleum ether. Asetshenziswa ngokuyinhloko ekwakhiweni kwe-emulsifiable concentrates (EC). Izidingo ezibalulekile zifaka amandla aqinile okuncibilika, ubuthi obuphansi, iphoyinti eliphezulu, ukungashi, izindleko eziphansi, nokutholakala okubanzi.
·Ama-Emulsifiers.
Ama-surfactants azinza ukusakazeka koketshezi olulodwa olungabonakali (isb., uwoyela) luye kolunye (isb., amanzi) njengamaconsi amancane, akha i-emulsion e-opaque noma i-semi-opaque. Lezi zibizwa ngokuthi ama-emulsifiers. Izibonelo ezijwayelekile zifaka ama-ester asuselwa ku-polyoxyethylene noma ama-ether (isb, uwoyela we-castor polyoxyethylene ether, i-alkylphenol polyethylene ether), uwoyela obomvu waseTurkey, kanye ne-sodium dilaurate diglyceride. Zisetshenziswa kakhulu ekugxilweni oku-emulsifiable, ukwakhiwa kwamanzi-emulsion, kanye nama-microemulsions.
·Abahlakaza.
Ama-surfactants asetshenziswa ekwenziweni kwezibulala-zinambuzane ukuvimbela ukuhlanganiswa kwezinhlayiya eziqinile ezinhlelweni zokuhlakazwa koketshezi oluqinile, okuqinisekisa ukumiswa kwazo okufanayo kwesikhathi eside oketshezini. Izibonelo zifaka i-sodium lignosulfonate ne-NNO. Asetshenziswa ngokuyinhloko ekukhiqizeni izimpushana ezimanzi, ama-granules ahlakazeka ngamanzi, kanye nokumiswa kwamanzi.
