Cov tshuaj surfactantsua haujlwm ua cov neeg sawv cev ntub, dispersing, emulsifying thiab solubilizing hauvkev ua cov tshuaj tua kabthiab tau dhau los ua cov khoom tseem ceeb ntawm cov tshuaj tua kab. Lawv kuj feem ntau hu ua cov neeg sawv cev pabcuam, emulsifiers, dispersants thiab adjuvants, uas tuaj yeem yog cov sib xyaw ua ke ntawm ntau yam surfactants. Tam sim no, cov tshuaj tua kab tab tom hloov pauv mus rau cov khoom siv dej, granular, ntau yam kev ua haujlwm, tso qeeb, txuag zog thiab kho kom zoo. Muaj ntau yam tshiab ua haujlwm tau zoo, muaj kev nyab xeeb, tsim nyog tus nqi thiab sib haum xeeb rau ib puag ncig suav nrog microemulsions, aqueous emulsions, suspoemulsions, water-dispersible granules, qhuav flowables thiab qeeb-tso formulations tab tom tshwm sim thiab yuav tswj hwm kev tsim cov tshuaj tua kab hauv xyoo pua 21st. Qhov kev thov rau surfactants coj los ntawm cov tshuaj tua kab tshiab no yuav tsav tsheb tshawb fawb, kev txhim kho thiab kev tsim cov surfactants tshwj xeeb rau cov tshuaj tua kab. Cov qauv kev txhim kho ntawm surfactants hauv agrochemicals hauv ob peb xyoos tom ntej yog raws li nram no:
(1) Raws li cov yam ntxwv nquag ntawm cov tshuaj tua kab,cov tshuaj suspension concentratestsis tsom mus rau cov khoom xyaw nquag siab thiab hloov mus rau cov ntsiab lus nruab nrab hloov chaw, thaum cov khoom tiav lawm yuav tsum tau nruab nrog cov khoom ntub dej zoo heev, kis tau thiab synergistic, ua rau muaj kev cai nruj dua rau surfactants.
(2) Raws li lub hauv paus ntawm kev ua kom ruaj khov rau lub sijhawm ntev, emulsion hauvcov qauv dejlub hom phiaj yog kom txo qhov nro ntawm cov kua tshuaj tsuag thiab muab cov khoom nrog kev nthuav dav thiab khaws cov dej noo. Cov tshuaj tua kab uas muaj glyphosate tab tom tsim los ua cov khoom muaj cov ntsiab lus siab dua, uas tsav tsheb kev txhim kho ntxiv ntawm cov hom ntsev tsim thiab cov neeg sawv cev ntub thiab nkag mus.
(3) Kev loj hlob thiab kev nrov ntawmkev ncua rojcov tshuaj concentrates tau loj hlob sai, tab sis feem ntau cov khoom uas twb muaj lawm tsis zoo tsis ruaj khov hauv kev ruaj khov ntawm kev ncua thiab kev tawg ntawm tus kheej, uas yuav tsum tau kho sai li sai tau.
(4) Kev txhim kho ntawmkev tsim cov kua dej tawmtab tom nce ntxiv nrov, thiab cov khoom xyaw tshiab ua ke xav tau cov surfactants nrog cov qauv zoo dua rau lawv cov yam ntxwv.
(5) Kev nce qib ntawm R&Dcov tshuaj tua kab mobthiab cov qauv sib xws suav nrog WP, SC thiab WG tab tom nrawm dua. Cov qauv ib txwm ua los ntawm cov khoom siv fermentation uas muaj protein thiab qab zib tsis tuaj yeem phim cov khoom lag luam uas twb muaj lawm ntawm agrochemical surfactants, ua rau qhov xav tau kev tsim cov surfactant tshiab sai dua.
(6) Cov tshuaj tua kab ib txwm muaj nrog cov pob txha benzene rings tab tom raug tshem tawm sai sai, thiab cov tshuaj tua kab tshiab uas muag feem ntau yog cov tshuaj heterocyclic. Tam sim no, qhov feem pua ntawm cov tshuaj tua kab uas tsis yaj sai sai poob qis thaum cov uas yaj sai sai nce siab; cov qauv siv cov hydrocarbons uas muaj ntxhiab tsw qab me me ua cov kuab tshuaj tab tom txo qis nrog rau kev hloov pauv ntawm cov qauv hauv cov kuab tshuaj; cov tshuaj emulsifiable concentrates uas muaj cov ntsiab lus siab thiab cov tshuaj emulsifiable concentrates uas tsis muaj kuab tshuaj tab tom raug tsim kho hnyav. Tag nrho cov kev hloov pauv no ua rau muaj kev cov nyom rau cov txheej txheem agrochemical surfactant ib txwm muaj los ntawm cov tshuaj tua kab benzene-ring-based thiab cov kuab tshuaj hydrocarbon uas muaj ntxhiab tsw qab, hu rau kev tsim kho tshiab hauv kev ua liaj ua teb surfactants.
