Cov Tshuaj Tua Kab Mob yog cov tshuaj ntxiv thaum lub sijhawm ua lossis siv cov tshuaj tua kab los txhim kho lawv cov khoom siv physicochemical, tseem hu ua cov tshuaj tua kab adjuncts. Txawm hais tias adjuvants lawv tus kheej feem ntau muaj me ntsis lossis tsis muaj kev ua haujlwm ntawm lub cev, lawv tuaj yeem cuam tshuam rau qhov ua tau zoo ntawm kev tswj kab tsuag. Nrog rau kev siv dav dav thiab kev txhim kho ntawm cov tshuaj tua kab adjuvants, lawv ntau yam tau txuas ntxiv nthuav dav, ua rau kev xaiv cov adjuvant zoo yog qhov teeb meem thib ob loj tshaj plaws rau cov neeg ua liaj ua teb tom qab xaiv cov tshuaj tua kab nws tus kheej.
1.Cov tshuaj adjuvants uas pab txhawb kev sib kis ntawm cov khoom xyaw nquag
Cov Khoom Sau thiab Cov Neeg Nqa Khoom
Cov no yog cov khoom siv tsis muaj zog, cov nroj tsuag, lossis cov khoom siv hluavtaws ntxiv thaum lub sijhawm ua cov tshuaj tua kab kom kho qhov concentration ntawm cov khoom kawg lossis txhim kho nws lub cev. Cov khoom sau yog siv los ua kom cov khoom xyaw nquag thiab txhim kho nws cov kev sib kis, thaum cov neeg nqa khoom kuj ua haujlwm los nqus lossis nqa cov khoom siv zoo. Piv txwv li suav nrog av nplaum, av diatomaceous, kaolin, thiab av nplaum av nplaum.
Cov khoom sau feem ntau yog cov khoom tsis muaj zog xws li av nplaum, av nplaum av nplaum, kaolin, av diatomaceous, pyrophyllite, thiab hmoov talcum. Lawv lub luag haujlwm tseem ceeb yog kom dilute cov khoom xyaw nquag thiab nqus nws. Lawv feem ntau yog siv rau hauv kev tsim cov hmoov, cov hmoov ntub dej, cov hmoov, thiab cov hmoov uas yaj tau hauv dej. Cov tshuaj tua kab thiab chiv sib xyaw ua ke tam sim no nrov heev. (lossis "cov chiv tshuaj") siv cov chiv ua cov tshuaj tua kab, sib koom ua ke ob qho tib si kom ua tiav kev siv ua ke.
Cov Neeg Nqa Khoom tsis yog tsuas yog dilute cov khoom xyaw nquag tab sis kuj pab nqus nws, ua lub luag haujlwm tseem ceeb hauv kev ruaj khov ntawm cov mis.
·Cov kuab tshuaj
Cov tshuaj organic siv los yaj thiab ua kom cov khoom xyaw nquag ntawm cov tshuaj tua kab, ua rau lawv yooj yim rau kev ua thiab siv. Cov kuab tshuaj feem ntau suav nrog xylene, toluene, benzene, methanol, thiab petroleum ether. Lawv feem ntau yog siv rau hauv kev tsim cov emulsifiable concentrates (EC). Cov kev cai tseem ceeb suav nrog lub zog yaj muaj zog, tsis muaj tshuaj lom, qhov kub siab, tsis kub hnyiab, tus nqi qis, thiab muaj ntau.
·Cov khoom ua kom cov emulsifiers
Cov tshuaj surfactants uas ua kom cov kua dej uas tsis sib xyaw (piv txwv li, roj) ruaj khov rau hauv lwm cov kua (piv txwv li, dej) ua cov tee me me, tsim cov emulsion uas tsis pom tseeb lossis tsis pom tseeb. Cov no hu ua emulsifiers. Cov piv txwv feem ntau suav nrog polyoxyethylene-based esters lossis ethers (piv txwv li, castor oil polyoxyethylene ether, alkylphenol polyethylene ether), Turkey red oil, thiab sodium dilaurate diglyceride. Lawv siv dav hauv cov emulsifiable concentrates, water-emulsion formulations, thiab microemulsions.
·Cov tshuaj dispersants
Cov tshuaj surfactants siv rau hauv cov tshuaj tua kab kom tiv thaiv kev sib sau ua ke ntawm cov khoom khov hauv cov txheej txheem dispersion ntawm cov khoom khov thiab kua, kom ntseeg tau tias lawv cov dej nyob hauv cov kua tau ntev. Piv txwv li suav nrog sodium lignosulfonate thiab NNO. Lawv feem ntau yog siv rau hauv kev tsim cov hmoov ntub dej, cov hmoov uas yaj tau hauv dej, thiab cov dej uas yaj tau hauv dej.
