Ngā matū horoihe matū he hanganga matū ahurei, ā, e whakamahia whānuitia ana i roto i te umanga whakapaipai. He kai āwhina ēnei i roto i ngā hanganga whakapaipai—ahakoa he iti noa te rahinga e whakamahia ana, he mahi nui tā rātou. Kei roto i te nuinga o ngā hua ngā surfactants, tae atu ki ngā horoi kanohi, ngā hinu whakamakuku, ngā kirimi kiri, ngā shampoos, ngā conditioners, me te paraihe niho. He rerekē ā rātou mahi i roto i ngā whakapaipai, ko te nuinga ko te emulsification, te horoi, te pahuka, te whakarewa, te mahi antibacterial, ngā pānga antistatic, me te marara. Kei raro nei, ka whakamāramahia e mātou ā rātou mahi matua e whā:
(1) Te Whakapūtanga
He aha te emulsification? E mōhio ana tātou, ko ngā kirīmi me ngā hinu e whakamahia ana e tātou i roto i te tiaki kiri he mea hanga ki ngā wāhanga hinuhinu me te nui o te wai—he ranunga hinu me te wai. Heoi, he aha e kore ai e kitea e tātou ngā pata hinu, te wai rānei e turuturu ana ki te kanohi tahanga? Nā te mea he pūnaha marara ōrite tonu: ka tohatohahia ngā wāhanga hinuhinu hei pata ririki i roto i te wai, ka tohatohahia rānei te wai hei pata ririki i roto i te hinu. Ko te mea tuatahi ka kiia he emulsion hinu-i-roto-i-te-wai (O/W), ko te mea tuarua he emulsion wai-i-roto-i-te-hinu (W/O). Ko ngā whakapaipai o tēnei momo e mōhiotia ana ko ngā whakapaipai e hangai ana ki te emulsion, te momo tino noa.
I raro i ngā āhuatanga noa, kāore e taea te whakaranu i te hinu me te wai. Kia mutu te whakaoho, ka wehea kia rite ki ngā paparanga, ā, kāore e taea te hanga i tētahi marara pumau, ōrite. Heoi, i roto i ngā kirīmi me ngā hinu whakahinuhinu (ngā hua e ahu mai ana i te emulsion), ka taea e ngā wāhanga hinuhinu me te wai te hanga i tētahi marara ōrite, pai te whakaranu nā te tāpiri o ngā surfactants. Mā te hanganga ahurei o ngā surfactants ka taea e ēnei matū kore e taea te whakaranu kia ōrite, ka hanga he pūnaha marara pumau - arā, he emulsion. Ko tēnei mahi a ngā surfactants e kiia ana ko te emulsification, ā, ko ngā surfactants e mahi ana i tēnei mahi e kiia ana ko ngā emulsifiers. Nō reira, kei roto i ngā kirīmi me ngā hinu whakahinuhinu e whakamahia ana e tātou i ia rā ngā surfactants.
(2) Te Horoi me te Whakahuka
He tino pai ngā āhuatanga horoi me te pahuka o ētahi matū horoi kiri. Ko te hopi, he tauira rongonui, he momo matū horoi kiri e whakamahia whānuitia ana. Ka whakawhirinaki ngā hopi kaukau me ngā hopi pae ki ō rātou wāhanga hopi (ngā matū horoi kiri) hei whakatutuki i ngā pānga horoi me te pahuka. Ka whakamahia hoki e ētahi horoi kanohi ngā wāhanga hopi hei horoi. Heoi, he kaha te mana horoi o te hopi, ka taea te tango i ngā hinu tūturu o te kiri, ā, ka paku whakapataritari pea, ka kore ai e pai mō te kiri maroke, kiri tairongo rānei.
Hei tāpiri, ko ngā hinu kaukau, ngā hopi horoi makawe, ngā horoi ringa, me ngā paraihe niho, katoa ēnei e whakawhirinaki ana ki ngā matū horoi mō ā rātou mahi horoi me te whakaputa huka.
(3) Te whakarewatanga
Ka taea e ngā matū whakakoi te whakanui ake i te wairewatanga o ngā matū kāore e wairewa, kāore rānei e wairewa pai ki te wai, kia memeha rawa ai, kia hanga ai he otinga mārama. Ka kiia tēnei mahi ko te whakakoi, ā, ko ngā matū whakakoi e mahi ana i tēnei mahi ka mōhiotia ko ngā kaiwhakakoi.
Hei tauira, ki te hiahia tātou ki te tāpiri i tētahi wāhanga hinuhinu tino makuku ki tētahi toner mārama, kāore te hinu e rewa ki te wai engari ka mānu hei pata ririki ki runga i te mata. Mā te whakamahi i te pānga whakarewa o ngā surfactants, ka taea e tātou te whakauru i te hinu ki roto i te toner, ka puta he āhua mārama, he āhua mārama. Heoi, he mea nui kia mōhio ko te nui o te hinu ka taea te whakarewa mā te whakarewa he iti noa iho—he uaua ki te rewa katoa ngā rahinga nui ki te wai. Nō reira, i te piki haere o te ihirangi hinu, me piki ake hoki te nui o te surfactant kia emulsified te hinu me te wai. Koia te take he āhua mātotoru, he mā miraka rānei ētahi toner: he nui ake te ōwehenga o ngā hinu makuku kei roto, ka emulsified ngā surfactants ki te wai.
