Kāo. He rerekē ngā hiahia hangahanga e tutuki ai te mahi sintering me te rewa, ā, he mea tautoko hoki.

kaua e taea te whakawhiti.

He mea nui te whakarewa mō:

*Ngā wāhanga hanganga nui
*Ngā huihuinga whakarewa
*Ngā tono e hiahia ana kia nui te ngāwari

He pai te mahi sintering mō:

*Ngā wāhanga tino tika
*Ngā wāhanga mahi pūwero
Ngā hua paerewa nui-rahi

Ko te whiriwhiri i waenga i ēnei ka whakawhirinaki ki te āhuahanga, ngā whakaritenga mahi, me ngā whāinga utu.

Q7: Ko tēhea tukanga e pai ake ai te tika o ngā āhuatanga?

Ko tēhea tukanga e pai ake ana te tika o ngā āhuatanga: te whakahinuhinu, te whakarewa rānei?

Ko te tikanga, he pai ake te whakahaere i ngā āhuatanga mō ngā wāhanga iti me ngā wāhanga uaua nā te mea:

*Ngā pokepokea tika

*He iti te rerekētanga i te wā e whakamahana ana

*Te hanga tata-āhua-kupenga

Ka pāngia te rewa me te whakarewa e te mimiti me te hē i te wā e totoka ana,

he maha ngā wā e hiahiatia ana he mīhini tāpiri hei whakatutuki i ngā manawanui pātata.

Nā tēnei ka tino pai te mahi sintering mō ngā pūoko, ngā wāhanga hauora, me ngā wāhanga moroiti-mīhini.

P8: He aha te rerekētanga o ngā hanganga moroiti i waenga i ngā konganuku kua whakatōngia me ngā konganuku kua rewa?

He aha te rerekētanga o ngā hanganga moroiti i waenga i ngā konganuku kua whakatōngia me ngā konganuku kua rewa?

Ko ngā konganuku kua whakakorikoria he mea hanga mai i ngā matūriki paura kua herea me ngā rohe i waenga i ngā matūriki kua whakahaeretia.

me te porosity kōwhiringa. Ka taea te hanga i tō rātou hanganga iti hei whakatutuki i te rere motuhake,

te tātari, ngā āhuatanga ā-pūkaha rānei.

Ka totoka ngā konganuku rewa mai i te āhua wai, ā, he maha ngā wā ka hanga he witi nui ake me ngā hanganga pumau.

Ahakoa ka taea e tēnei te whakarato i te kaha papatipu tino pai, kāore i a ia te ngāwari hanganga moroiti e rite ana ki te mahi whakarewa paura.

Mā tēnei rerekētanga taketake ka whakamārama he ahate whakarewa paura me te whakarewa tuku ihoka arahi ki

ngā āhuatanga rerekē o te mahi rauemi me ngā āheinga tono.

Whakamutunga

Te mārama ki te rerekētanga i waenga ite whakakorikori me te rewakoinei te taahiraa tuatahi ki te whiriwhiri

te tukanga hanga tino whai hua mō ō wāhanga whakarewa.

Hei āwhina i a koe ki te whakatau tika kia tere ake, kia māia hoki, ka tono atu mātou kia tūhuratia e koe

ngā rauemi e whai ake nei:

Te rapu ritengangā wāhanga maitai kore waikura kua whakapōturitiapērā i ngā tātari, ngā kaiwhakarere,

ngā wāhanga tino tika rānei?

Ka taea e tā mātou tīma hangarau te āwhina i a koe ki te whiriwhiri i te rauemi tika, te rahi o ngā pore, me te hanga.
