Zopangira madzi oundanaamagwira ntchito ngati zinthu zonyowetsa, zobalalitsa, zosakaniza ndi zosungunulira mukukonza mankhwala ophera tizilombondipo akhala zigawo zofunika kwambiri pakupanga mankhwala ophera tizilombo. Amatchulidwanso kuti othandizira, ma emulsifier, ma dispersants ndi ma adjuvants, omwe amatha kukhala osakaniza amitundu yosiyanasiyana ya ma surfactants. Pakadali pano, mapangidwe a mankhwala ophera tizilombo akusintha kukhala zinthu zochokera m'madzi, zopyapyala, zogwira ntchito zambiri, zotulutsa pang'onopang'ono, zopulumutsa ntchito komanso zoyengedwa bwino. Mitundu yatsopano yambiri yogwira ntchito bwino, yotetezeka, yotsika mtengo komanso yogwirizana ndi chilengedwe kuphatikizapo ma microemulsions, ma emulsions amadzi, ma suspoemulsions, ma granules omwazika m'madzi, ma flowables ouma ndi ma slow-release formulations akubwera ndipo adzalamulira chitukuko cha mankhwala ophera tizilombo m'zaka za m'ma 2000. Kufunika kwa ma surfactants omwe abwera ndi mankhwala atsopano ophera tizilombo kudzayendetsa kafukufuku, chitukuko ndi kupanga ma surfactants apadera a mankhwala ophera tizilombo. Kukula kwa ma surfactants mu agrochemicals m'zaka zingapo zikubwerazi ndi motere:
(1) Kutengera ndi makhalidwe ogwira ntchito a mankhwala ophera tizilombo,zosakaniza zoyimitsidwaSizimayang'ananso zinthu zomwe zili ndi zinthu zambiri zogwira ntchito ndipo zimasintha kukhala zapakati, pomwe zinthu zomalizidwa ziyenera kukhala ndi zinthu zabwino kwambiri zonyowetsa, kufalitsa komanso kugwirizana, zomwe zimapangitsa kuti pakhale zofunikira kwambiri pa zinthu zosungunulira.
(2) Pansi pa mfundo yotsimikizira kukhazikika kwa nthawi yayitali, emulsion mkatimapangidwe amadziCholinga chake ndi kuchepetsa kwambiri kupsinjika kwa pamwamba pa madzi opopera ndikupatsa zinthuzo ntchito zofalitsa ndi kusunga chinyezi. Mayankho a mankhwala ophera tizilombo amadzimadzi omwe amaimiridwa ndi glyphosate akupangidwa kukhala zinthu zokhala ndi zinthu zambiri, zomwe zimapangitsa kuti mitundu yopanga mchere ipitirire komanso zinthu zonyowetsa komanso zolowa m'malo mwake zisinthe.
(3) Kupititsa patsogolo ndi kutchuka kwakuyimitsidwa kochokera ku mafutaZinthu zokhuthala zakula mofulumira, komabe zinthu zambiri zomwe zilipo zikuvutika ndi khalidwe losakhazikika pankhani ya kukhazikika kwa kuyimitsidwa ndi kufalikira kwa zinthu, zomwe ziyenera kuthetsedwa mwachangu momwe zingathere.
(4) Kukula kwama suspoemulsionsKutchuka kukuchulukirachulukira, ndipo kuphatikiza zinthu zatsopano zogwira ntchito kumafuna ma surfactants okhala ndi kapangidwe kogwirizana bwino ndi mawonekedwe awo.
(5) Liwiro la kafukufuku ndi chitukuko chamankhwala ophera tizilombo toyambitsa matendandipo mankhwala ofanana nawo kuphatikizapo WP, SC ndi WG akuchulukirachulukira. Mankhwala opangidwa kuchokera ku mapuloteni ndi shuga omwe ali ndi fermentation sangafanane ndi zomwe zilipo kale za agrochemical surfactants, zomwe zikufulumizitsa kufunikira kwa kupanga mankhwala atsopano a surfactant.
(6) Mankhwala ophera tizilombo akale okhala ndi mafupa a benzene ring akuchotsedwa mwachangu, ndipo mankhwala ophera tizilombo atsopano omwe amagulitsidwa kwambiri ndi mankhwala a heterocyclic. Pakadali pano, chiwerengero cha mankhwala ophera tizilombo otsika-kusungunuka chikuchepa pomwe cha omwe ali ndi mfundo yayikulu-kusungunuka chikukwera; mapangidwe ogwiritsa ntchito ma hydrocarbons opepuka ngati zosungunulira akuchepa kuchuluka pamodzi ndi kusintha kwa kapangidwe kake m'zinthu zosungunulira; zinthu zambiri zosungunuka zomwe zimakhala ndi zinthu zambiri komanso zinthu zopanda zosungunulira zomwe sizimasungunuka zikukula kwambiri. Kusintha konseku kumabweretsa mavuto ku machitidwe achikhalidwe a agrochemical surfactant ochokera ku mankhwala ophera tizilombo ochokera ku benzene-ring ndi zosungunulira za hydrocarbon zopepuka, zomwe zimafuna kuti pakhale luso lamakono mu zinthu zosungunulira zaulimi.
