He rauemi mata tino parakore, kua whakarerekētia hoki te whakamātotoru ahumahi. Ka taea e ia te whakapai ake i te ātete wera, te ātete kakahu, te tiaki wera, te ārai koroheketanga me ētahi atu mahi matū o te hua, ā, he tino pai te kaha whakamātotoru me te kaha whakatārewatanga. Hei tāpiri, he pai hoki te marara o te kiko, ā, he whānuitia ngā whakamahinga.
Ko te whakamātotoru ahumahi te nuinga o te wā e whakamahia ana hei pupuri wai, hei whakamātotoru, hei whakaū me te mea hou i roto i ngā paninga hoahoanga, i te putty hoahoanga, i te papa sima pahuka, i te moata whakamahana wera o waho me te raupapa o ngā paninga ārai-pakaru me te ārai-wai. Ka whakakanapahia te paninga, ka ātaahua, ka whakapai ake i te pānga hanga me te whakapakari i te kaha o te piri. Ka whakaitihia te nui o te paura rapa, te sima, te konupūmā raima, te paura gypsum me ētahi atu here kore-waro, ka whakaitihia hoki ngā utu whakaputa.
Te whakamahinga e taunakitia ana mō ngā whakamātotoru ahumahi:
I mua i te whakamahinga o te whakamātotoru ahumahi, whakaritea he ipu, tāpirihia he wai e tika ana ki roto, kātahi ka tāpirihia he whakamātotoru e tika ana (0.2%-1.0% o te ranunga katoa), ā, me whakaoho tonu mō te rima meneti. I tēnei wā, ki te hiahiatia he uara pH, ka taea e koe te tāpiri i te wai toenga me te whanariki ka whakaoho mō ētahi atu rima meneti kia eke ki tētahi matotoru. Ina whakamahi ana i ngā whakamātotoru, ko te mea tuatahi hei aro atu ko te wā. He rerekē te horopeta i te raumati me te hotoke, ā, ko te rerekētanga i waenga i ngā wā e rua he hauwhā. I taua wā anō, tāpirihia he wai tote ka mutu te whakaoho, kia teitei ake ai te mārama.
Ngā whakatūpato mō te whakamahi i te whakamātotoru ahumahi:
Tuatahi, me mōhio kei roto i ngā whakamātotoru ahumahi ngā matū polymer hydrophilic, nō reira i te tukanga whakamahinga, me whiriwhiri te whakamātotoru e tika ana te mahi kia rite ki ngā whakaritenga whakamahinga. I taua wā anō, he rite te pānga o te whakamātotoru ahumahi pai ake ki te tiēre, nō reira he pānga taurite. Kātahi ka aro tātou ki te whanaungatanga tata i waenga i te kukū me te ōritetanga o te whakamātotoru ahumahi. Ina iti te ōritetanga, he iti noa te matotoru, nō reira me whakahaere te horopeta i te wā e whakaranu ana.
Hei whakamutunga, ki te whakanohoia te whakamātotoru ahumahi ki roto i te wai, ka tino ngoikore te mahi whakarewa, ā, ka roa te wā kia tino hanumi. I ētahi wā ka puta he āhuatanga kāore i te ōrite. Hei karo i ēnei āhuatanga kino, me whakarite tuatahi ngā ipu kua whakahuatia i runga ake nei, whakaranua, ka tāpirihia kia kotahi te wā, kātahi ka whakaohokia kia kotahi te wā.
