Mukushandiswa kwemishonga yezvipembenene, kushandiswa kwakananga kwechinhu chinoshanda hakuwanzo. Mazhinji magadzirirwo anosanganisira kusanganisa mishonga yezvipembenene neadjuvants uye zvinonyungudutsa kuti zviwedzere kushanda uye kuderedza mitengo. Masurfactants akakosha adjuvants anowedzera kuita kwemishonga yezvipembenene uku achidzikisa mari, kunyanya kuburikidza ne emulsification, kupupa furo / kuburitsa furo, kupararira, uye kunyorova mhedzisiro. Kushandiswa kwavo kwakapararira mukugadzira mishonga yezvipembenene kwakanyatso kunyorwa.
Masurfactants anovandudza kusawirirana kwechiso pakati pezvikamu mu emulsions, kugadzira uniform uye yakagadzikana yekuparadzira masisitimu. Chimiro chavo cheamphiphilic - kubatanidza hydrophilic uye lipophilic mapoka - inogonesa adsorption panzvimbo yemafuta-mvura. Izvi zvinoderedza kusawirirana kwechiso uye kuderedza simba rinodiwa pakuumbwa kwemulsion, nekudaro kunowedzera kugadzikana.
Kuparadzira mushonga wezvipembenene unoshanda mumvura sezvo madiki-scale particles achipa kushanda kwepamusoro zvichienzaniswa nemamwe maumbirwo. Emulsifiers inokanganisa zvakananga kugadzikana kwepesticide emulsions, iyo inozotarisa kushanda kwayo.
Kugadzikana kunosiyana nekukura kwedonhwe:
● Zvimedu <0.05 μm: Yakanyungudutswa mumvura, yakagadzikana zvikuru.
● Zvikamu 0.05-1 μm: Zvizhinji zvakanyungudutswa, zvakagadzikana.
● Zvimedu 1–10 μm: Kunyura kana kunaya nekufamba kwenguva.
● Zvimedu > 10 μm: Zvinooneka zvakaturikwa, hazvina kugadzikana zvakanyanya.
Sezvo zvimiro zvemishonga yezvipembenene zvinoshanduka, ane muchetura organophosphates ari kutsiviwa neimwe yakachengeteka, inoshanda zvakanyanya, uye yakaderera-chepfu dzimwe nzira. Heterocyclic compounds-zvakadai sepyridine, pyrimidine, pyrazole, thiazole, uye triazole derivatives-kazhinji inovapo sezvimedu zvine kunyungudika kwakaderera mumagetsi emazuva ose. Izvi zvinodikanwa novel, yepamusoro-soro, yakaderera-chepfu emulsifiers pakuumbwa kwavo.
China, mutungamiri wepasi rose mukugadzirwa kwemishonga yezvipembenene uye kushandiswa, yakashuma 2.083 mamiriyoni ematani ekugadzirwa kwepesticide-giredhi muna 2018. Kuwedzera kuziva kwezvakatipoteredza kwakakonzera kudiwa kwekugadzirwa kwepamusoro-soro. Nekuda kweizvozvo, kutsvagisa nekushandiswa kweeco-hushamwari, yepamusoro-soro mishonga yezvipembenene yakawana mukurumbira. Masevhisi emhando yepamusoro, sezvinhu zvakakosha, anoita basa rakakosha mukusimudzira matekinoroji emishonga yezvipembenene.
