I roto i ngā whakamahinga patupatu, he onge te whakamahinga tika o te matū hohe. Ko te nuinga o ngā hanganga he whakaranu i ngā patupatu me ngā tāpiringa me ngā whakarewa hei whakanui ake i te whai huatanga me te whakaiti i ngā utu. Ko ngā matū whakaora matū he tāpiringa matua e whakanui ana i te mahi patupatu me te whakaiti i ngā whakapaunga, ko te nuinga mā te whakaemulsification, te pahuka/whakakore pahuka, te horapa, me ngā pānga mākū. Kua tuhia pai te whakamahinga whānui o ēnei i roto i ngā hanganga patupatu.
Ka whakapai ake ngā matū horoi i te taumahatanga ā-kanohi i waenga i ngā wāhanga i roto i ngā emulsion, ka hanga he ōritem me ngā pūnaha marara pumau. Nā tō rātou hanganga amphiphilic—te whakakotahi i ngā rōpū hydrophilic me lipophilic—ka taea te mimiti i ngā atanga hinu-wai. Ka whakaitihia e tēnei te taumahatanga atanga me te whakaiti i te pūngao e hiahiatia ana mō te hanganga emulsion, ā, ka whakarei ake i te pumau.
Mā te horapa o ngā matūriki hohe o ngā patu pepeke ki roto i te wai hei matūriki iti ka puta he mahi pai ake i ērā atu momo hanga. Ka pā tika ngā emulsifier ki te pumau o ngā emulsion patu pepeke, ā, ka whakatau i tōna whai huatanga.
Ka rerekē te pumau i runga i te rahi o te pata:
● Ngā matūriki <0.05 μm: Ka wairewa i roto i te wai, he tino pumau.
● Matūriki 0.05–1 μm: He nui te wairewa, he āhua pumau.
● Ngā matūriki 1–10 μm: Te whakatōtōtanga wāhanga, te ua rānei i roto i te wā.
● Ngā matūriki >10 μm: E kitea ana te iri, he tino kore pumau.
I te whanaketanga o ngā hanganga o ngā patu pepeke, kei te whakakapia ngā organophosphate tino paitini ki ngā momo kē atu haumaru ake, whai hua ake, ā, iti iho te paitini. Ko ngā matū heterocyclic—pērā i te pyridine, pyrimidine, pyrazole, thiazole, me ngā triazole derivatives—he maha ngā wā ka noho hei totoka he iti te wairewa i roto i ngā whakarewa tuku iho. Nā tēnei, me hanga he emulsifier hou, whai hua nui, iti iho te paitini mō tā rātou hanganga.
Ko Haina, he kaiārahi o te ao mō te hanga me te kai i ngā patu pepeke, i ripoata i te 2.083 miriona tana o ngā patu pepeke hangarau i te tau 2018. Nā te pikinga ake o te mōhiotanga ki te taiao kua akiaki i te hiahia mō ngā hanganga kounga teitei. Nō reira, kua piki ake te rongonui o te rangahau me te whakamahinga o ngā patu pepeke mahi-teitei, hoa-taiao. Ko ngā matū horoi kounga teitei, hei wāhanga nui, he mea nui ki te whakatairanga i ngā hangarau patu pepeke pumau.
