Pesticide Adjuvants yog cov khoom pab ntxiv thaum lub sijhawm ua haujlwm lossis siv cov tshuaj tua kab los txhim kho lawv cov khoom siv physicochemical, tseem hu ua tshuaj tua kab. Txawm hais tias adjuvants lawv tus kheej feem ntau tsis tshua muaj kev lom zem, lawv tuaj yeem cuam tshuam rau kev ua tau zoo ntawm kev tswj kab tsuag. Nrog rau kev siv dav thiab kev loj hlob ntawm cov tshuaj tua kab mob, lawv cov ntau yam tau nthuav dav ntxiv, ua rau kev xaiv cov tshuaj tua kab yog qhov nyuaj thib ob rau cov neeg ua liaj ua teb tom qab xaiv cov tshuaj tua kab nws tus kheej.
1.Adjuvants uas pab nyob rau hauv Active Ingredient Dispersioncov
· Fillers thiab Carrierscov
Cov no yog cov ntxhia pob zeb tsis muaj zog, cov nroj tsuag-raws li, lossis cov khoom siv hluavtaws ntxiv thaum lub sijhawm ua cov khoom siv tshuaj tua kab los kho cov khoom kawg ntawm qhov concentration lossis txhim kho nws lub cev lub cev. Fillers yog siv los dilute cov khoom xyaw nquag thiab txhim kho nws cov kev tawg, thaum cov nqa khoom kuj ua haujlwm rau adsorb lossis nqa cov khoom siv tau zoo. Cov piv txwv muaj xws li av nplaum, diatomaceous ntiaj teb, kaolin, thiab av nplaum av nplaum.
Fillers feem ntau yog cov khoom nruab nrab tsis muaj zog xws li av nplaum, cov av nplaum nplaum, kaolin, diatomaceous ntiaj teb, pyrophyllite, thiab talcum hmoov. Lawv lub luag haujlwm tseem ceeb yog dilute cov khoom xyaw nquag thiab adsorb nws. Lawv tsuas yog siv rau hauv kev tsim cov hmoov, cov hmoov ntub dej, granules, thiab dej-dispersible granules. Tam sim no nrov tshuaj tua kab-fertilizer ua ke (los yog "cov tshuaj chiv") siv cov chiv ua cov khoom siv tshuaj tua kab, sib koom ua ke ob qho tib si kom ua tiav daim ntawv thov sib koom ua ke.
covCov neeg nqa khoom Tsis tsuas yog dilute lub active ingredient tab sis kuj pab adsorb nws, ua si lub luag hauj lwm tseem ceeb nyob rau hauv formulation stability.
·Cov kuab tshuajcov
Organic tshuaj siv los yaj thiab dilute cov khoom xyaw nquag ntawm cov tshuaj tua kab, ua kom yooj yim rau lawv ua thiab siv. Cov kuab tshuaj muaj xws li xylene, toluene, benzene, methanol, thiab roj av ether. Lawv feem ntau yog siv rau hauv kev tsim cov emulsifiable concentrates (EC). Cov kev xav tau tseem ceeb suav nrog lub zog muaj zog tawg, tsis muaj tshuaj lom, lub teeb nyem siab, tsis muaj nplaim taws, tsis tshua muaj nqi, thiab muaj dav dav.
·Emulsifierscov
Surfactants stabilize lub dispersion ntawm ib tug immiscible kua (piv txwv li, roj) mus rau lwm yam (xws li, dej) raws li me me droplets, tsim ib tug opaque los yog semi-opaque emulsion. Cov no yog hu ua emulsifiers. Cov piv txwv xws li polyoxyethylene-based esters lossis ethers (piv txwv li, castor roj polyoxyethylene ether, alkylphenol polyethylene ether), Turkey liab roj, thiab sodium dilaurate diglyceride. Lawv tau siv dav hauv emulsifiable concentrates, dej-emulsion formulations, thiab microemulsions.
·Dispersantscov
Surfactants siv nyob rau hauv cov tshuaj tua kab formulations los tiv thaiv cov aggregation ntawm cov khoom hais nyob rau hauv cov khoom-kua dispersion systems, kom ntseeg tau tias lawv mus sij hawm ntev uniform suspension nyob rau hauv cov kua. Piv txwv suav nrog sodium lignosulfonate thiab NNO. Lawv feem ntau yog siv rau hauv kev tsim cov hmoov ntub dej, dej-dispersible granules, thiab dej ncua kev kawm ntawv.
