● Te tohatoha wera whai hua i roto i ngā mīhini ahumahi
● Ngā rauemi atanga wera i roto i ngā pūnaha rokiroki pūngao me ngā pūnaha pākahiko

Ngā Whakamahinga Pūngao me te Mīhini

● Ngā wāhanga mō ngā pūtau wahie, ngā miihini, me ngā pūnaha whakaputa hau
● Ngā tono whakaiti me te pēhi i te wiri
● Ngā arai ātete-waikura i roto i ngā taputapu tukatuka matū

Ka taea te whakarite i ngā rau karāhe ngāwari kia tutuki ai ngā whakaritenga matotoru, kiato, me te mahi mō ngā tono ahumahi kanorau.

Ngā Painga ki ngā Rauemi Kē

Ki te whakaritea ki ngā rauemi hiri, rauemi wera rānei tuku iho pērā i te PTFE, ngā pepa whakarewa, ngā elastomer rānei, he maha ngā painga o ngā pepa karāhe ngāwari:

● He ātete pāmahana tino pai, tae atu ki te 450–500°C i roto i ngā āhuatanga waikura, ā, he teitei ake anō hoki i roto i ngā āhuarangi kore mahi
● He tino pumau te matū, ātete ki te whānuitanga o ngā momo pāpāho kaha
● Te ngāwari ki te hanga i ngā mata kāore i te ōrite, te whakapai ake i te mahi hiri
● He roa te ora o te ratonga, e whakaiti ana i te auau o te whakakapinga me ngā utu tiaki
● He otinga māmā e kore e whakararu i te kounga o te hanganga

Nā ēnei painga ka waiho ngā pepa karāhe ngāwari hei whiringa pai i roto i ngā taiao ahumahi uaua.

Me pēhea te whiriwhiri i te pepa whakairoiro ngāwari tika

I te wā e whiriwhiri ana i tētahi pepa karāhe ngāwari mō te whakamahinga ahumahi, me whai whakaaro ngā kaihoko pakihi-ki-te-ipurangi ki:
