I ngā āhuatanga pāmahana teitei pērā i te tiaki wera ahumahi me te whakamarumaru wera oumu, ka iti ake te kounga oparaikete muka ukuKa whakatau tika i te haumaru whakahaere o ngā taputapu me ngā utu whakapaunga pūngao. Heoi, he rerekē rawa te kounga o ngā hua kei te mākete. Me pēhea te aromatawai tere me te tika i te kounga o ngā paraikete muka uku? Kia matatau ki ngā āhuatanga matua e toru e whai ake nei kia ngāwari ai te karo i ngā hē i te hoko.
Tuatahi, tirohia te āhua me te matotoru—he "hua pai i te tirohanga tuatahi" ngā paraikete muka uku kounga teitei. He papatahi, he ōrite te mata o te hua pai, kāore he pupuhi, he kapiti, he ira poke rānei, ā, he pai te tohatoha o te muka me te kore e piri. Ina pāngia e te ringa, he ngawari, he ngāwari te ahua, ā, kāore e ngāwari te marere o ngā toenga, te pakaru rānei. I taua wā anō, ka taea e koe te whakataurite i te matotoru mā te pauna noa—mō ngā hua he matotoru ōrite, ko ngā mea he matotoru tika (ko te tikanga 96-128kg/m³, i runga i te horopaki tono) he pakari ake, ā, he pumau ake te mahi whakamahana. Mena he māmā rawa te ahua o te hua, he angiangi rawa, he wetewete rānei ngā muka, tera pea he hua ngoikore me ngā kokonga tapahi, ka ngāwari ki te huri me te hinga i muri i te whakamahinga roa.
Tuarua, whakamātauria te mahi matua, ā, manatokohia te pono mā te whakamahi i ngā "tikanga mahi". Ko te ātete pāmahana teitei te tohu matua. Ka taea e ngā paraikete muka uku kounga teitei te tu atu i ngā pāmahana teitei o te 1000-1400℃ (e rite ana ki te tauira hua). I te hoko, ka taea e koe te tono ki te kaiwhakarato kia homai he tauira, ā, tunua te taha ki te rama mō te wā poto. Mena kāore he mura tuwhera, kāore he kakara kino, ā, kāore he mimiti, he rerekētanga rānei i muri i te whakamatao, he tohu te ātete pāmahana teitei. Engari, ki te mea he paoa, he rewa, he kakara kirihou rānei, he hua kāore i te tohu. Hei tāpiri, ka taea te aromatawai i te mahi whakamahana wera mā te tikanga "whakamātautau pāmahana ringaringa": pā atu ki te paraikete e hipoki ana i te mata o te pūtake wera ki tō ringaringa. Mena he iti te pāmahana o waho, ā, kāore he urunga wera e kitea ana, he tohu pai te pānga whakamahana wera. I taua wā anō, ka maroke ngāwari ngā hua kounga teitei i muri i te mimiti wai, ā, ka noho tonu te mahi i muri i te whakamaroke, ko ngā hua kino ka pāngia e te kino o te hanganga nā te mimiti wai.
Hei whakamutunga, tirohia ngā tiwhikete me ngā waitohu hei karo i ngā tūponotanga me ngā "whakaaetanga ngaio". Ko ngā paraikete muka uku i hangaia e ngā kaihanga noa ka whai tiwhikete kounga e mōhiotia ana i te ao, pērā i te tiwhikete CE me te tiwhikete paerewa ISO. Me whai pūrongo whakamātautau paerewa GB/T hoki ngā hua o te whare. I te hoko, ka taea e koe te tono ki te kaiwhakarato kia whakaatu i ēnei tiwhikete hei karo i te hoko hua "toru-kāore" (kāore he kaihanga, kāore he rā whakaputa, kāore he tiwhikete kounga). I te wa ano, me whakatairanga i ngā waitohu he maha ngā tau o te wheako ahumahi. Ehara i te mea he tukanga whakaputa pakeke noa iho ēnei umanga, engari ka whakarato hoki i ngā tawhā hua mārama (pērā i te hanganga, te awhe ātete pāmahana, te kawe wera) me te ratonga muri-hoko. Mena ka puta he raruraru i te wā e whakamahia ana i muri mai, ka taea te whakatau i te wā tika. Heoi, he maha ngā tawhā koretake o ngā hua mai i ngā awheawhe iti, ā, kāore he taurangi muri-hoko. Ahakoa te ahua iti te utu, he nui ake ngā utu tiaki i muri mai.
Mā te whiriwhiri i ngā paraikete muka uku kounga teitei ka taea te penapena i te neke atu i te 30% o ngā utu whakapaunga pūngao mō te hanga ahumahi, ā, ka roa ake te roa o te ora o ngā taputapu. Kia matatau ki ngā tikanga wehewehe i te kounga mai i te āhua, te manatoko i te mahi, me te whakarite i te pono mā roto i ngā tiwhikete, kia pau ai ia tahua ki ngā "kaupapa matua" me te hanga i tētahi arai haumaru me te whakamahana pakari mō ngā āhuatanga pāmahana teitei.
