I te pikinga ake o te hiahia mō te kounga o te hau o roto me te whakangawari i te pūngao,ngā whakawhiti wera uku honikoma- he rauemi ahumahi tuku iho e wera ana i te pāmahana teitei - kei te uru atu ki ngā pūnaha hau hou. Ko tōna hanganga motuhake, te mahi pumau, me te whakamahinga anō ka whakatau i ngā uauatanga matua o ngā pūnaha tuku iho, pērā i te utu whakakapinga tātari teitei me te poto o te ora ratonga, ka tutuki ai te maimoatanga hau o roto he pai me te ohanga.
He rauemi whānui te whakamahinga o te mīhini whakawhiti wera uku honikoma i roto i te ao ahumahi, ā, he mahi nui tāna i roto i te pūnaha hau hou. Nā te hanganga ahurei o te tinana rokiroki wera uku honikoma, ka nui ngā painga o te uruhanga hau me te pai o te whakawhiti wera. Kei raro nei, ka matapakihia e mātou te whai wāhi a ngā tinana rokiroki wera uku honikoma ki te whakahaere i ngā pūnaha hau hou.
1. Ngā āhuatanga hanganga me te uruhanga hau
Ko te hanganga o te pūwhakaora rokiroki wera uku honikoma he maha ngā pūwero hexagonal, he tapawhā rānei e tata ana te whakarite, e whakarato ana i te ara "huarahi" rite ki te ara mō ngā ngota hau. Mā tēnei hanganga ka taea e ngā ngota hau te tomo ki ngā pūwero me te kore he arai, ka tīmata i tētahi 'haerenga tere-nui' whai hua. Kāore i rite ki ētahi atu rauemi he uaua, he uaua hoki ngā hanganga moroiti, he tika, he tonu hoki ngā pūwero o ngā pūwhakaora rokiroki wera uku honikoma, e whakaiti nui ana i ngā tukinga me ngā arai o ngā ngota hau i a rātou e neke ana.
2. Te whakawhiti wera i roto i te pūnaha hau hou
I roto i te pūnaha hau hou, ko te rokiroki wera uku honikoma te mea nui e whakamahia ana mō ngā tukanga whakawhiti wera. Ina haere te hau paowa pāmahana teitei mā roto i te kaiwhakahou uku honikoma, ka whakawhitia te wera ki te tinana rokiroki wera tonu. Muri iho, ina hiahiatia te whakamahana i te hau hou, ka tukuna te wera e rongoatia ana i roto i te kaiwhakahou rokiroki wera ka whakawhitia ki te hau matao e rere ana i te taha ke atu i ngā pūwero. I roto i tēnei tukanga, mā te tere o te urunga o te hau ka taea te whakawhiti wera pai, ka whakapai ake i te whakamahinga pūngao, ā, ka taea e te pūnaha hau hou te mahi me te iti o te whakamahinga pūngao.
- Ko te hanganga taketake he tinana uku porotaka o te honikoma, e whakamahi ana i ngā rauemi hou me ngā ōwehenga pūtaiao me ngā āhuatanga ahurei. Ko te hangarau whakakoi whakaputanga ka hangaia mā te tahu pāmahana tino teitei.
- 1. Mā te paninga ārai-pokepoke me te ātete-makuku ka ārai i te pāmahana nui o roto me te kohikohinga o te pokepoke. 2. Ka hangarua i ngā ngota wai mai i te hau, ka mau tonu te pāmahana haumākū. 3. He ngāwari ki te horoi, kāore he parahanga tuarua, ā, he roa te ora mahi.
- 1. Ka taea te tango i te pūngao mai i te hau whakaputa hei whakarato i te hau mō te whakamahana, te whakamatao rānei. 2. Ko te pai o te penapena me te tuku wera he 97%, ā, he rawaka te whakawhiti.
- 1. He tino kaha te mimiti, te rokiroki, me te tuku wera, ā, hei matua whakawhiti wera katoa, he mahi whakaora pūngao tōna. 2. Ka eke te tere whakaora wera ki te 97%.
He whānuitia te whakamahinga i roto i ngā tari, i ngā kura me ngā whare tūmatanui, ā, he pai mō te hauhautanga o te wāhi nui. Mēnā ka tika te whirihoranga o ngā pūnaha, ka taea te horoi i te hau i roto i te radius 2.5km, e whakaatu ana i te kaha ki te whakapai ake i te hau ā-rohe.
I roto i te ahumahi, ka whakauruhia ēnei ki roto i ngā pūnaha hau hou o te wheketere he nui te VOC, ka tātari i ngā matūriki me te pirau i ngā hau kino mā roto i ngā tauhohenga whakaterenga, e whakamahia ana i roto i ngā tipu matū me ngā tipu hiko mō te whakahaere rua i te hauhautanga-parahanga.
