Ko te waituhi hinu te tikanga o te waituhi hei whakawaiwai i te tae i roto i te hinu, pērā i te hinu kohuke, te hinu huawhenua, me ētahi atu. Ka piri te waituhi ki te rauemi mā te mimiti hinu me te mimiti i runga i te rauemi tā; ka whakamahia e te waituhi wai te wai hei rauemi marara, ā, ka noho te waituhi ki runga i te rauemi tā. Ka piri te tae ki te rauemi mā te mimiti wai me te mimiti.
E wehewehea ana ngā waituhi i roto i te umanga whakaahua i runga i ō rātou whakamahinga. Ka taea te wehewehe kia rua ngā momo: Ko tētahi, ko ngā waituhi wai, e whakamahi ana i ngā wairewa wai me ngā wairewa wai hei wāhanga matua hei whakarewa i te turanga tae. Ko tētahi atu ko te waituhi hinu, e whakamahi ana i ngā wairewa kore-wai hei wāhanga matua hei whakarewa i te turanga tae. E ai ki te wairewatanga o ngā wairewa, ka taea hoki te wehewehe kia toru ngā momo. Tuatahi, ko ngā waituhi tae, e ahu mai ana i ngā tae, e whakamahia ana e te nuinga o ngā mīhini whakaahua o roto i ēnei rā; tuarua, ko ngā waituhi pigment, e ahu mai ana i ngā waituhi pigment, e whakamahia ana i roto i ngā pūreretā waituhi o waho. Tuatoru, ko te waituhi eco-solvent, kei waenganui, e whakamahia ana i runga i ngā mīhini whakaahua o waho. Me aro nui ki ēnei momo waituhi e toru kāore e taea te whakaranu. Ka taea anake e ngā mīhini wai te whakamahi i ngā waituhi wai, ā, ka taea anake e ngā mīhini hinu te whakamahi i ngā waituhi wairewa ngoikore me ngā waituhi wairewa. Nā te mea he rerekē ngā kātere, ngā paipa, me ngā pūwero waituhi o ngā mīhini wai me ngā mīhini hinu ina tāutahia te mīhini, kāore e taea te whakamahi noa i te waituhi.
E rima ngā āhuatanga matua e pā ana ki te kounga o te waituhi: te waituhi whakamarara, te kawe hiko, te uara PH, te kukū o te mata, me te matotoru.
1)Kaiwhakamarara: He matū hohe mata, ko tana mahi he whakapai ake i ngā āhuatanga ā-tinana o te mata waituhi, me te whakarei ake i te piripono me te ngāwari o te waituhi me te hautai. Nō reira, ko te waituhi e rongoatia ana, e arahina ana hoki mā roto i te hautai, he mea whakamarara te nuinga.
2)Te Ahumahi: Ka whakamahia tēnei uara hei whakaata i te taumata o te tote. Mō ngā waituhi kounga pai ake, kaua te tote e neke ake i te 0.5% hei karo i te hanganga o ngā tioata i roto i te pūwero. Ko te waituhi hinu te mea e whakatau ana ko tēhea pūwero hei whakamahi i runga i te rahi o te tae. Ko ngā pūreretā waituhi nui 15pl, 35pl, me ētahi atu e whakatau ana i te tika o te pūreretā waituhi i runga i te rahi o te matūriki. He mea tino nui tēnei.
3)Uara PH: e pā ana ki te uara pH o te wai. Ka nui ake te waikawa o te wairewa, ka iti iho te uara PH. I tetahi atu taha, ka nui ake te kawakore o te wairewa, ka teitei ake te uara PH. Hei ārai i te waituhi kei waikura te pūwero, me noho te uara PH i waenga i te 7-12.
4)Te kukū o te mata: Ka pā ki te kaha o te waituhi ki te hanga pata. He iti te matotoru o te waituhi kounga pai, ā, he nui te kukū o te mata.
5)Mātotoru: Ko te ātete o te wai ki te rere. Mēnā he nui rawa te mātotoru o te waituhi, ka aukati i te rere o te waituhi i te wā e tā ana; ki te iti rawa te mātotoru, ka rere te pane waituhi i te wā e tā ana. Ka taea te penapena i te waituhi mō te 3-6 marama i te pāmahana rūma noa. Mēnā he roa rawa, he ua rānei, ka pā ki te whakamahinga, ki te puru rānei. Me hiri te wāhi penapena waituhi kia kore ai e whiti tika te rā. Kaua te pāmahana e tino tiketike, e tino iti rānei.
