ngā whakatūpato mō te whakamahi i te pango whanariki

whanariki pango 240%He matū ngota nui tēnei kei roto he nui ake te whanariki, kei roto i tōna hanganga he hononga disulfide me ngā hononga polysulfide, ā, he tino pūmau. Ina koa, ka taea te whakahāngai i te hononga polysulfide ki te waikura whanariki mā te hāora i te rangi i raro i ētahi āhuatanga pāmahana me te haumākū, ā, ka taunekeneke atu ki ngā ngota wai i te rangi hei whakaputa waikawa whanariki, ka whakaiti i te kaha o te miro, te pakarukaru o te muka, ā, ka pakarukaru ngā muka katoa hei paura ina tino kino. Mō tēnei take, hei whakaiti, hei ārai rānei i te kino o te pakarukaru o te muka i muri i te tae ki te tae pango whakamomona, me mōhio ēnei āhuatanga e whai ake nei:

① Me whakawhāiti te nui o te tae pango kua whakamomonatia, ā, kaua te nui o te tae tae motuhake kua whakamomonatia e neke atu i te 700g/pōkai. Nā te nui o te tae, he nui te tūponotanga o te pakarukaru, ā, ka heke te pakari o te tae, ā, ka uaua ake te horoi.

② I muri i te tae, me horoi katoa kia kore ai e poke te horoinga, ā, he ngāwari te pirau o te tae mānu i runga i te miro hei waikawa whanariki i te wā e rongoa ana, ka pakarukaru ai te muka.

③ I muri i te tae, me whakamahi te urea, te pungarehu houra me te konutai acetate hei rongoā ārai-pakaru.

④ Ka kohuatia te miro ki te wai ma i mua i te tae, ā, he pai ake te ngokingoki o te miro i taehia ki te wai ma i te rai i muri i te tae.

⑤ Me whakamaroke te miro i muri i te tae, nā te mea he ngāwari te whakamahana i te miro mākū i roto i te tukanga puranga, kia iti ai te ihirangi o te kaihoko ārai-pakaru miro, kia iti ai te uara pH, kāore e pai mō te ārai-pakaru. I muri i te whakamaroketanga o te miro, me whakamatao māori, kia taea ai te takai i te pāmahana o te miro i mua i te hekenga ki te pāmahana rūma. Nā te mea kāore i whakamataohia i muri i te whakamaroketanga me te takai tonu, kāore e ngāwari te tohatoha i te wera, ka whakanui ake i te kaha mō te pirau o te tae me te waikawa, ka puta te tūponotanga o te muka kia pakarukaru.

⑥Ko te kōwhiringa o ngā tae pango anti-brittle-whanariki, kua tāpirihia ēnei tae ki te formaldehyde me te waikawa chloroacetic i te wā e hangaia ana, ko te hua o te methyl-chlorine he anti-brittle-black vulcanized, kia noho ai ngā ngota whanariki ngāwari ki te āhua hanganga pumau, ka taea te aukati i te waikura o ngā ngota whanariki ki te whakaputa waikawa me te muka pakarukaru.
