Whakamahinga
Tāpiri tukatuka rapaKa taea te whakamahi i te hinu whakarewa hei whakangawari me te whakapūmau i te rapa. I te wā e whakaranua ana te rapa, ka taea e ia te uru ki waenga i ngā mekameka ngota rapa, te whakanui ake i te tawhiti i waenga i ngā mekameka ngota rapa, me te whakaiti i te pakeke me te modulus o te rapa. Hei tauira, i te tukatuka rapa maori, mā te tāpiri i te nui o te hinu whakarewa e tika ana ka taea te whakangawari ake i te rapa me te ngāwari ake mō ngā tukanga whakakoi i muri mai pēnei i te extrusion me te calendering. Ka taea hoki e ia te whakapai ake i te piri o te rapa. I te wā e whakarārangihia ana te rapa me ētahi atu tukanga tukatuka, ka taea e te hinu whakarewa te hoatu i te piri tika ki te mata rapa hei whakahaere i te whakarārangi i waenga i ngā wāhanga rapa rerekē. Hei tauira, i te wā e hanga ana i ngā potae motuka, me whakarārangihia ngā wāhanga rerekē o te potae (pēnei i te takahanga, te pakitara taha, te raina o roto, me ētahi atu). Ka taea e te hinu whakarewa te āwhina i ēnei wāhanga kia pai ake te piri tahi. Piripiri rapa e hangai ana ki te whakarewaWhakamahia hei whakarite i te piripiri rapa e hangai ana ki te whakarewa. Ka taea e te hinu whakarewa te whakarewa i ngā wāhanga rapa hei hanga i te piripiri matotoru. Ka taea te whakamahi i tēnei piripiri hei hono i waenga i te rapa me te rapa, me waenga i te rapa me ētahi atu rauemi (pēnei i te konganuku, te kirihou). Hei tauira, i roto i te hanga hū, ka taea e te piripiri rapa he whakarewa te here pūmau i te rapa o te kapu me te rauemi o runga kia pai ai te kounga me te roa o te mahi a ngā hū.
He whakarewa ahumahi nui te hinu whakarewa. I tēnei wā, e 400 ki te 500 ngā momo whakarewa kei te mākete. Ko tana whakamahinga matua he whakatutuki i ngā whāinga motuhake mā roto i ngā tukanga pēnei i te whakarewa me te whakapūkara. He whānui rawa ngā whakamahinga o te hinu whakarewa. Ko te hinu whakarewa peita (e mōhiotia whānuitia ana ko te whakangāwari peita) te mea nui rawa atu, ā, muri iho ko ngā hinu whakarewa mō ngā hinu kai, ngā waituhi tā, te hiako, ngā patu pepeke, ngā patu pepeke, te rapa, ngā whakapaipai, ngā kakara, ngā rongoā, ngā wāhanga hiko, me ētahi atu. Ko te "wai" e whakamahia ana e ngā toa horoi kakahu hei horoi i ngā kākahu papai ko te hinu whakarewa horoi maroke.
Ko te hinu whakarewa tētahi o ngā wāhanga matua e rima o ngā hua hinu. He whānuitia ngā whakamahinga o te hinu whakarewa. Ko te mea e whakamahia whānuitia ana ko te hinu whakarewa paninga (e mōhiotia whānuitia ana ko te hinu whakarewa peita), ā, muri iho ko ngā hinu kai, ngā waituhi tā, te hiako, ngā patu pepeke, ngā patu pepeke, te rapa, ngā mea whakapaipai, ngā kakara, ngā rongoā, ngā wāhanga hiko, me ētahi atu hinu whakarewa. E 400-500 ngā momo whakarewa e hokona ana i te mākete, ā, ko te haurua o ēnei ko te hinu whakarewa (ngā whakarewa hauwaiwaro, ngā matū benzene). He ranunga matatini o ngā hauwaiwaro te hinu whakarewa, ā, he tino mura, he pahū hoki. Nō reira, mai i te hanga, te rokiroki me te kawe ki te whakamahinga, me tino ārai i te putanga mai o ngā ahi.
Te Tākai me te Tukunga
