Hei whakapai ake i te pakeketanga o te mata me te ātete ki te kakahu oNgā ngongo tapawhā 16Mn, ko te maimoatanga mata, pēnei i te mura mata, te tinei mata auau-teitei, te maimoatanga wera matū, me ētahi atu, me mahi mō ngā ngongo tapawhā. I te nuinga o te wā, ko te nuinga o ngā mata auau-teitei me te auau-waenga ka tineihia, ā, ko te pāmahana whakamahana he 850-950 nekehanga. Nā te ngoikore o te kawe wera, kaua e tere rawa te tere whakamahana. Ki te kore, ka puta ngā kapiti rewa me ngā kapiti tinei. Ko te tinei auau-teitei me whakamahi te pearlite hei whakamatao i te nuinga o te matrix kua whakaritea. Ko te rehu wai, te waipiro polyvinyl rānei hei whakamatao. Ko te pāmahana whakamahana he 200-400 ℃, ā, ko te pakeke he 40-50hrc, ka taea te whakarite i te pakeke me te ātete kakahu o tengongo tapawhāmata.
Me mārama ngā kōrero matua e whai ake nei i te wā e tinei anaNgongo tapawhā 16Mn:
(1)Kaua te paipa roa e whakamahana poutū i roto i te oumu kaukau tote, i te oumu puna rānei, kia kore ai e rerekē te āhua o te paipa i puta mai i tōna taumaha kupenga.
(2)Ina whakamahanahia ngā paipa me ngā wāhanga rerekē i roto i te oumu kotahi, me whakanoho ngā paipa iti ki te pito o waho o te oumu, ā, me tatau motuhake ngā paipa nui me ngā paipa iti.
(3)Me rite te nui o te utu ki te taumata mana o te oumu. Mēnā he nui te nui o te whāngai, ka māmā te pēhanga me te piki o te pāmahana, ā, me roa ake te wā whakamahana.
(4)Ko te pāmahana tinei o ngā ngongo tapawhā tapawhā kua tineihia ki te wai, ki te tote rānei hei rohe o raro, ā, ko te pāmahana tinei o te hinu, te tote rewa rānei kua tineihia hei rohe o runga.
(5)I te wā e tinei ana i te reo rua, me whakahaere te wā noho i roto i te reo tinei tuatahi e ai ki ngā tikanga e toru o runga ake nei. Me poto te wā neke mai i te reo tinei tuatahi ki te reo tinei tuarua, ko te mea pai ko te 0.5-2 hēkona.
(6)Ko ngā paipa e āraia ana te mata o te waikura, o te tango waro rānei, me whakamahana i roto i te oumu kaukau tote kua whakaritea, i roto rānei i te oumu hau tiaki. Mēnā kāore e tutuki i ngā whakaritenga, ka taea te whakamahana i roto i te oumu ātete hau, engari me mahi ngā mahi tiaki.
(7)I muri i te rumakina poutū o te ngongo tapawhā 16Mn ki roto i te wai tinei, kāore e nekeneke, e neke ake ana, e heke iho ana, ā, ka mutu te whakaoho o te wai tinei.
(8)Mena kāore e ranea te kaha whakamatao o ngā wāhanga e hiahia ana ki te pakeketanga teitei, ka taea te rumaki i te wāhanga katoa ki roto i te reo tinei i te wā kotahi, ā, ka taea te whakamatao i ngā wāhanga mā te rehu wai hei whakapai ake i te tere whakamatao.
(9)Me whakanoho ki tētahi wāhi whakamahana whai hua. Mā te nui o te utu, te tikanga utu me te āhua whakarārangi e whakarite kia ōrite te pāmahana whakamahana, ā, kia kore ai e puta he rerekētanga me ētahi atu hapa.
(10)I te wā e whakamahanahia ana i roto i te oumu tote, kaua e tata rawa ki te hikohiko kia kore ai e wera rawa. Me neke atu i te 30mm te tawhiti. Ko te tawhiti mai i te pakitara o te oumu me te hohonutanga o te rumaki i raro i te taumata wai me ōrite ki te 30mm.
(11)Ka taea te whakamahana tika i te maitai hanganga me te maitai waro i roto i te oumu me te pāmahana tinei 20-30 ℃ teitei ake i te pāmahana tinei. Me whakamahana anō te maitai waro-nui me te maitai koranu-nui ki te 600 ℃, kātahi ka whakanuia ki te pāmahana tinei.
(12)Ka taea te whakanui ake i te pāmahana tinei mō ngā paipa he paparanga whakapakeke hohonu, ā, ka taea te whiriwhiri i te pāmahana tinei iti mō ngā paipa he paparanga whakapakeke papaku.
(13)Me kore he hinu, he hopi, he paru rānei i te mata o te ngongo tapawhā 16Mn. Ko te tikanga, kaua te pāmahana o te wai e neke ake i te 40 ℃.
