Kodi ma surfactants amagwiritsidwa ntchito bwanji mu mankhwala ophera tizilombo?

Mu mankhwala ophera tizilombo, kugwiritsa ntchito mwachindunji mankhwala ophera tizilombo n’kosowa kwambiri. Mankhwala ambiri amaphatikizapo kusakaniza mankhwala ophera tizilombo ndi mankhwala owonjezera ndi zosungunulira kuti awonjezere mphamvu ndi kuchepetsa ndalama. Mankhwala ophera tizilombo ndi othandiza kwambiri omwe amawonjezera mphamvu ya mankhwala ophera tizilombo pamene amachepetsa ndalama zomwe zimagwiritsidwa ntchito, makamaka kudzera mu emulsification, thovu/defoaming, dispersion, ndi wetting effects. Kugwiritsa ntchito kwawo kofala m’mankhwala ophera tizilombo kwalembedwa bwino. 

Ma surfactants amathandiza kuti pakhale kusagwirizana pakati pa zigawo mu emulsions, zomwe zimapangitsa kuti pakhale uniform ndi machitidwe okhazikika ogawanikirana. Kapangidwe kawo ka amphiphilic—kuphatikiza magulu okonda madzi ndi okonda lipophilic—kumathandizira kuyamwa kwa madzi pamalo olumikizirana ndi mafuta. Izi zimachepetsa kupsinjika kwa interfacial ndikuchepetsa mphamvu yofunikira popanga emulsion, motero kumawonjezera kukhazikika.

Kumwaza zosakaniza zogwira ntchito za mankhwala ophera tizilombo m'madzi pamene tinthu tating'onoting'ono timapereka ntchito yabwino kwambiri poyerekeza ndi mitundu ina. Ma emulsifiers amakhudza mwachindunji kukhazikika kwa ma emulsions a mankhwala ophera tizilombo, zomwe zimatsimikiza momwe amagwirira ntchito.

Kukhazikika kumasiyana malinga ndi kukula kwa madontho:

● Tinthu tosakwana 0.05 μm: Tosungunuka m'madzi, tokhazikika kwambiri.

● Tinthu tating'onoting'ono 0.05–1 μm: Tomwe timasungunuka kwambiri, tokhazikika bwino.

● Tinthu tating'onoting'ono 1–10 μm: Kugwa pang'ono kwa nthaka kapena mvula pakapita nthawi.

● Tinthu >10 μm: Tinthu tomwe timaoneka tokha, tosakhazikika kwambiri.

Pamene mapangidwe a mankhwala ophera tizilombo akusintha, ma organophosphates oopsa kwambiri akusinthidwa ndi njira zina zotetezeka, zogwira mtima, komanso zopanda poizoni. Ma chemicals a Heterocyclic—monga pyridine, pyrimidine, pyrazole, thiazole, ndi triazole derivatives—nthawi zambiri amakhala olimba omwe amasungunuka pang'ono m'zosungunulira wamba. Izi zimafuna ma emulsifiers atsopano, ogwira ntchito bwino, komanso opanda poizoni wambiri kuti apange.

China, yomwe ndi mtsogoleri padziko lonse lapansi pakupanga ndi kugwiritsa ntchito mankhwala ophera tizilombo, inanena kuti mankhwala ophera tizilombo okwana matani 2.083 miliyoni apezeka mu 2018. Kudziwa bwino zachilengedwe kwapangitsa kuti pakhale kufunika kwa mankhwala abwino kwambiri. Chifukwa chake, kafukufuku ndi kugwiritsa ntchito mankhwala ophera tizilombo omwe ndi abwino komanso othandiza kwambiri pa chilengedwe atchuka kwambiri. Mankhwala ophera tizilombo abwino kwambiri, monga zigawo zofunika kwambiri, amachita gawo lofunikira kwambiri pakupititsa patsogolo ukadaulo wokhazikika wa mankhwala ophera tizilombo.
