E ai ki ngā momo rerekē o te pēki motuka, ka taea te wehewehe ki te waipēhingongo parai, ngongo parai hau me te ngongo parai korehau. E ai ki tōna rauemi, ka wehea ki te ngongo parai rapa, te ngongo parai nairona me te ngongo parai PTFE
He pai ngā painga o te ngongo parai rapa, arā, he kaha te kume me te ngāwari o te tāutanga, engari ko te ngoikoretanga he ngāwari te tawhito o te mata i muri i te whakamahinga roa.
Mēnā he iti te pāmahana, ka ngoikore te kaha kume o te ngongo parai nairona, ā, ki te pāngia e ngā kaha o waho, ka ngāwari te pakaru.
Engari he ātete pāmahana teitei, he ātete pāmahana iti, he ātete pēhanga teitei, he ātete kakahu, he ātete waikura me ētahi atu āhuatanga o ngā ngongo PTFE, he roa te ora ratonga, kāore e hiahiatia he whakakapinga pinepine. Ka taea e ia te whakakapi i ngā ngoikoretanga o ētahi atu rauemi e rua.
Ko te haumaru, te roa o te ora, me te mahi pai me waiho hei kaupapa matua māu. Kua whakamātauhia te E85, te etanoru rānei, hei wahie whai hua, ā, ka taea te whakarato i te tau octane me te kaha e hiahiatia ana mō ngā tono uaua. Engari ka taea e ngā tāpiringa i roto i ngā wahie hou te whakapakeke me te whakakino i te nuinga o ngā rauemi. Ka taea e tēnei te arahi ki ngā turuturu morearea, ā, ka waiho he haunga kino. Kia pakaru te raina wahie, ka taea e ngā matūriki ngongo ngoikore te poke me te aukati i ngā awa werohanga wahie me te carburetor, ka pā ki te mahi me te whakaputa raruraru.
Ko te otinga pai ko te rauemi polytetrafluoroethylene (PTFE). He rauemi kirihou te PTFE, koia te ngongo wahie angiangi rawa, māmā rawa hoki. Ka whakakotahi i te maitai kore waikura 304 he mea whiri ki roto i te ngongo PTFE maeneene hei whakanui ake i te rere, ā, he tino ngāwari te hanganga o waho. He pai te ngongo PTFE o roto mō te whakamahi me tetahi wahie, ā, ka taea te tu atu i ngā pāmahana tae atu ki te 260 nekehanga Celsius. Kāore te rauemi e pāngia e te pirau o te wahie, nō reira kāore ngā kohu wahie e turuturu ki waho.
Ngā taunakitanga whānui mō ngā pūnaha wahie:
I te tāutanga o tētahiNgongo PTFEi runga i ngā waka, me pupuri ngā ngongo wahie kia matara atu i ngā pūtake wera, i ngā taha koi me ngā wāhanga e neke ana. Me waiho he āputa nui mō te nekehanga o te pūnaha hiko. Tirohia te āputa i waenga i ngā wāhanga whakatārewatanga me te pūnaha tuku. Me whakarite kia tirohia ngā wāhanga whakatārewatanga puta noa i te tukanga kia kore ai e pēhia, e toro rānei ngā ngongo wahie. Mō ngā ngongo wahie e pāngia ana e ngā paru rori me ngā pāmahana teitei, whakamahiaNgā ngongo wahie PTFEhe mea whiri ki te maitai kore waikura, ki te waea mārō rānei. Kia tino piri te ngongo kia kore ai e pakaru. Ka āwhina hoki te jig ki te whakaiti i te wiri o ētahi atu wāhanga. Whakamahia ngā hononga wehewehe tika ina ngongo ana mā roto i ngā panera
Tērā pea ka pai anō hoki ki a koe
