Ni iyihe mirimo y'ibinyabutabire mu kwisiga?

Surfactantsni ibintu bifite imiterere yihariye cyane ya chimique kandi bikoreshwa cyane mu nganda z'ubwiza. Bikora nk'ibintu by'inyongera mu miterere y'ubwiza—nubwo bikoreshwa mu rugero ruto, bigira uruhare runini. Imiti ikoreshwa mu kwisiga iboneka mu bicuruzwa byinshi, harimo isukura mu maso, amavuta yo kwisiga, amavuta yo kwisiga ku ruhu, shampoo, conditioner, n'umuti wo koza amenyo. Imirimo yayo mu kwisiga iratandukanye, cyane cyane harimo gukurura, gusukura, gufuro, gushonga, gukora bagiteri, ingaruka zo kurwanya static, no gukwirakwiza. Hasi, turasobanura inshingano zayo enye z'ingenzi:

(1) Gutunganya ibinyabutabire

Emulsification ni iki? Nkuko tubizi, amavuta n'amavuta dukoresha mu kwita ku ruhu akubiyemo ibintu birimo amavuta n'amazi menshi—ni uruvange rw'amavuta n'amazi. Nyamara, kuki tudashobora kubona ibitonyanga by'amavuta cyangwa amazi atemba n'amaso yacu? Ibi biterwa nuko bikora sisitemu ikwirakwira cyane: ibice by'amavuta bisakara kimwe nk'ibitonyanga bito mu mazi, cyangwa amazi agakara kimwe nk'ibitonyanga bito mu mavuta. Iya mbere yitwa emulsion y'amavuta mu mazi (O/W), mu gihe iya nyuma ari emulsion y'amazi mu mavuta (W/O). Amavuta yo kwisiga nk'aya azwi nka emulsion-based cosmetics, ubwoko bukunze kugaragara cyane.

Mu bihe bisanzwe, amavuta n'amazi ntibishobora kuvanga. Iyo birangiye kuvanga, biratandukana, ntibibashe gukora ikwirakwira rihamye kandi ringana. Ariko, mu mavuta n'amavuta (ibicuruzwa bishingiye kuri emulsion), ibice by'amavuta n'amazi bishobora gukora ikwirakwira rivanze neza kandi ringana bitewe no kongeramo imiti ikoreshwa mu gupima. Imiterere yihariye y'imiti ikoreshwa mu gupima ituma ibi bintu bidahinduka bivanga neza, bigatuma habaho uburyo bwo gupima buhamye—ni ukuvuga emulsion. Uyu murimo w'imiti ikoreshwa mu gupima witwa emulsification, kandi imiti ikoreshwa mu gupima ...

(2) Gusukura no Gutanga Ifuro

Hari imiti isukura neza kandi itera ifuro. Isabune izwi cyane, ni ubwoko bwa miti isukura neza. Isabune yo koga n'isabune zo mu bwoko bwa bar zikoresha ibice byazo by'isabune (surfactants) kugira ngo zikore isuku no gusohora ifuro. Hari imiti isukura mu maso ikoresha ibice by'isabune mu gusukura. Ariko, isabune ifite imbaraga zo gusukura cyane, zishobora gukuraho amavuta karemano ku ruhu kandi zishobora gutera ububabare gato, bigatuma idakoreshwa ku ruhu rwumye cyangwa rworoshye.

Byongeye kandi, gel zo kwiyuhagira, shampoo, oza intoki, n'amenyo y'amenyo byose bikoresha surfactants kugira ngo bisukure kandi bikureho ifuro.

(3) Gushonga kw'amazi

Imiti ikoreshwa mu gushonga ishobora kongera ubushobozi bwo gushonga mu bintu bidashonga cyangwa bidashonga neza mu mazi, bigatuma ishonga burundu igakora umuti ubonerana. Uyu murimo witwa gushonga, kandi imiti ikoreshwa mu gushonga mu gushonga mu mazi izwi nka imiti ikoreshwa mu gushonga mu gushonga.

Urugero, niba dushaka kongeramo igice cy’amavuta gitanga ubushyuhe bwinshi kuri toner isobanutse, amavuta ntazashonga mu mazi ahubwo azatemba nk'utudomo duto hejuru. Dukoresheje imbaraga za surfactants zitanga ubushyuhe, dushobora gushyiramo amavuta muri toner, bigatuma igaragara neza kandi igaragara. Ariko, ni ngombwa kumenya ko ingano y'amavuta ashobora gushonga binyuze mu gushonga ari mike - ingano nini iragoye gushonga neza mu mazi. Kubwibyo, uko amavuta yiyongera, ingano ya surfactant nayo igomba kwiyongera kugira ngo ivange amavuta n'amazi. Niyo mpamvu amwe mu ma toner asa n'aho adasobanutse cyangwa asa n'umweru: arimo igice kinini cy'amavuta atanga ubushyuhe, ayo surfactants zitanga amazi hamwe n'amazi.
