lNgā Āhuatanga o te Hua:
1) Kua hangaia tēnei pūnaha nakunaku me te oumu nakunaku whakawera piko hei tinana matua, me te kohikohinga hau putanga me te whakakorenga hau putanga. Ka tutuki i a ia te otinga o te tukanga tukatuka tauira mā te pāwhiri kotahi mai i te ① nakunaku tauira → ② kohikohinga hau putanga → ③ maimoatanga whakakorenga hau putanga → ④ mutu te whakamahana ina oti te nakunaku → ⑤ wehea te ngongo nakunaku mai i te tinana whakamahana ka whakamatao mō te tatari. Ka tutuki i a ia te aunoatanga o te tukanga nakunaku tauira, ka whakapai ake i te taiao mahi, ka whakaiti i te kawenga mahi a ngā kaiwhakahaere.
2) Te kimi i te whata ngongo kei te wāhi tika: Ki te kore te whata ngongo e whakanohoia tika, ka whakaoho te pūnaha, ā, kāore e mahi, ka ārai i te kino o ngā taputapu nā te kore o ngā tauira e whakahaerehia ana, te hē rānei o te whakatakotoranga o ngā ngongo.
3) Te paepae ārai-parahanga me te pūnaha whakaoho: Ka taea e te paepae ārai-parahanga te ārai i te wai waikawa mai i te putanga kohikohi hau putanga mai i te whakapoke i te tēpu whakahaere, i ētahi atu taiao rānei. Ki te kore te paepae e tangohia, ā, ki te whakahaeretia te pūnaha, ka whakaoho, ka mutu te mahi.
4) Ko te oumu nakunaku he taputapu nakunaku me te hurihanga tauira i whakawhanakehia i runga i te kaupapa nakunaku mākū matarohia. E whakamahia ana i roto i te ahuwhenua, te ngahere, te tiaki taiao, te matawhenua, te hinu, te matū, te kai me ētahi atu tari, tae atu ki ngā whare wānanga me ngā whare rangahau mō te maimoatanga nakunaku o ngā tipu, purapura, whāngai kararehe, oneone, konganuku me ētahi atu tauira i mua i te tātari matū. Koinei te hua tino pai mō ngā tātari hauota Kjeldahl.
5) He pai te ōritetanga o te waeine whakamahana karāhe S, he iti hoki te ārai pāmahana, ā, kua hoahoatia kia eke ki te 550℃ te pāmahana.
6) He tere te whakamahana o te waeine whakamahana konumohe L, he roa te ora mahi, ā, he whānui te whakamahinga. Ko te pāmahana i hangaia he 450℃.
7) He mata pa tae 5.6-inihi te rahi o te mata o te pūnaha whakahaere pāmahana, ā, he māmā noa iho te whakahaere.
8) Ka whakamahia e te tāuru hōtaka tātai he tikanga tāuru tere e hangai ana ki te ripanga, he mea arorau, he tere, ā, he iti ake te tūponotanga o ngā hapa.
9) Ka taea te tīpako me te whakatakoto noa i ngā wāhanga 0-40 o ngā hōtaka.
10) Ka taea te whiriwhiri noa i ngā momo whakamahana kotahi-ira me te whakamahana pihi rua.
11) Mā te whakahāngai-ā-ringa P, I, D mohio ka whakarite kia teitei, kia pono, kia pumau hoki te tika o te whakahaere pāmahana.
12) Mā te pūhiko wehe me te mahi whakaara anō ārai-whakaweto ka ārai i ngā tūponotanga kino.
13) He rite rawa ki ngā kōwae tiaki pāmahana-rahi, pēhanga-rahi me te iahiko-rahi.
lPūrere kohikohi hau para
1. He mea hanga te taupoki hiri ki te polytetrafluoroethylene, he ātete ki te wera me te ātete ki ngā waikawa kaha me ngā kawakore.
2. He hanganga kōniko tōna me te uhi papatahi, ā, e 35 karamu te taumaha o ia uhi hiri.
3. Ko te tikanga hiri e whakamahi ana i te hiri taiao taumaha, he pono, he watea hoki
4. Ka toro hohonu te paipa kohikohi ki roto i te paipa hei kohi i te hau waikawa, kia tino pono ai
5. He mea whakarewa te anga ki ngā pereti maitai kore waikura 316, ā, he pai te mahi ārai-waikura.
lPūrere whakakore
1. He taputapu whakakore waikawa me te kawakore tēnei hua, he papu hau pēhanga kino kua hangaia ki roto. He nui te rere o te papu hau, he roa te ora mahi, ā, he ngāwari te whakahaere.
2. Ko te mimiti e toru-wāhanga o te otinga alkali, te wai māori me te hau e whakarite ana i te pono o te hau kua tukuna
3. He māmā, he haumaru, he pono hoki te whakamahi i te taputapu
