AWS A5.6 ECu
Whakaahuatanga: He hiko parahi parakore te T107, he parahi parakore te pūtake, ā, kua hipokina ki te momo rere konutai hauwai-iti. He DCEP (hiko au tika te pai). He pai ngā āhuatanga miihini, he pai te ātete ki te waikura ki te hau me te wai moana, kāore e pai mō te whakarewa i te parahi kei roto te hāora me te parahi hikohiko.
Te Whakamahinga: Ka whakamahia whānuitia mō te whakarewa i ngā wāhanga parahi pērā i ngā pae parahi kawe hiko, ngā whakawhiti wera parahi, me ngā paipa wai moana mō ngā kaipuke. Ka taea hoki te whakamahi mō te whakarewa mata o ngā wāhanga maitai waro e ātete ana ki te waikura wai.
Te hanganga matū o te konganuku whakarewa (%):
| Cu | Si | Mn | P | Pb | Fe+Al+Ni+Zn |
| ＞95.0 | ≤0.5 | ≤3.0 | ≤0.30 | ≤0.02 | ≤0.50 |
Ngā āhuatanga hangarau o te konganuku whakarewa:
| tūemi whakamātautau | Te kaha o te kume Mpa | Te whakaroa % |
| Kua whakamanahia | ≥170 | ≥20 |
Iahiko e taunakitia ana:
| Te whānui o te tokotoko （mm） | 3.2 | 4.0 | 5.0 |
| WhakarewaInāianei （A） | 120 ~ 140 | 150 ~ 170 | 180 ~ 200 |
Pānui:
1. Me tunu te hikohiko ki te pāmahana tata ki te 200°C mō te 1 hāora i mua i te whakarewanga, ā, me tango atu te makuku, te hinu, ngā waikura me ētahi atu poke i runga i te mata o te whakarewanga.
2. Nā te kawe wera o te parahi, ā, ko te pāmahana whakamahana o te rakau e whakarewahia ana he tino teitei, neke atu i te 500 °C. Me rite te kaha o te ia whakarewa ki te pāmahana whakamahana o te konganuku turanga; Whakamātauria te whakarewa pewa poto poutū. Ka taea te whakamahi mō te nekehanga raina tauutuutu hei whakapai ake i te hanganga whakarewa.
3. Mō ngā whakarewanga roa ake, ngana ki te whakamahi i te tikanga whakarewa whakamuri, ā, me tere te tere o te whakarewanga.
I te wā e whakarewahia ana ngā paparanga maha, me tango katoa te paru i waenga i ngā paparanga; i muri i te whakarewa, me patu te whakarewa ki te hama pane papatahi hei whakamama i te ahotea,
Whakapai ake i te kounga o te whakarewa.
