Ngā Piriponi

He pūtango whakapiri, e mōhiotia ana hoki hei pūtango Dowty rānei, he pūtango whakapiri, he mīhini whakapuaki i whakamahia hei hanga i tētahi pūtanga whakapiri tū whakaaro me te kore haere i waenganui i ngā rua mata. Ko tētahi wāhanga matua ko te pūtango mete ki te pūtanga whakapiri, me te āhua rubber rānei ki roto.

Ka mahi te pūtango whakapiri ki te whakawhana i ngā pūkenga whakapiri o te pūtango mete me te momo rubber. Ko te pūtango mete te whakarite i te whakatika wharewhare me te whakamahere kia tuwhera, nō reira ko te momo rubber te whakarite i ngā pūkenga whakapiri, ka huri, ka tirohia ki ngā mata e takoto ana ki a ia.

E ai ki tētahi whakamārama whānui, ko ēnei ngā wāhanga me ngā mahi a te pūtango whakapiri:

Pūtango Mete: Ko te pūtango mete kei te whai i te mete ahuwhenua, ko te ahuwhenua e tae ana ki te mata whakaaetanga rānei, me te whakarite wharewhare ki te pūtanga.

Waea Rū: Ko te waea rū, e whai ana i te Nitrile Butadiene Rubber (NBR) rānei ko ētahi atu elastomer, ka whakapiri ki te ārai roa o te perehi mete. Ka hanga te waea rū i te āheinga ki te tahuhu rānei e tūhono ana ki te pūnaha.

Āheinga: Ki te whakamātau te āheinga kia iti i waenganui i ngā tahuhu e rua, ka hāpaku te waea rū, ka whakarereke, ka hanga i te āheinga nui. Ka tirotiro te waea rū i ngā māmā rānei me ngā huanga kē o ngā tahuhu, ka tohua te korenga o ngā wai rānei me ngā hau.

Āheinga Whakatōpu: Ko te perehi mete ka awhina ki te whakawehenga o te pūtake hāpai ki runga i te waea rū, e whai ana ki te āheinga nui whakatika. Ka awhina anō ia ki te whakahē ki te whakaputu, e tūtaki ana te āheinga, ahakoa i ngā āhuatanga nui o te pūmau.

Kei raro i te maha o ngā tūtohu kei te whakamahi ngā pūtango whakapiri, ā, hei tūtohu i ngā rārangi wai, ngā tuaropaki, ngā whatu motokā, me ngā whakawehenga mahi. Ko te pai me te tumanako i te mahi o te whakapiri, ko te whiu ki te hopu, ko te hiahia hoki ki te whakaora i ngā hē o te mata, e mahi ana hei tika mō ngā tūtohu e hiahiatia ana he pai me te kore haere.
