He aha ngā tikanga whakaputa mō te pahuka parahi?

pahuka parahihe rauemi maha-mahi hou. Me pēhea te hanga? Inaa, pērā i te nuinga o ngā konganuku PahukaKo te pahuka parahi te mea matua e whakamahi ana i te parahi hei rauemi turanga. I te wā e hangaia ana, he maha ngā pūwero e hono tahi ana, e kore rānei e hono tahi ana, e tohatoha ōrite ana puta noa i te papa parahi.

Ehara i te mea ko ngā painga anake o te pahuka parahi he rite ki ngā konganuku pahuka, engari he rite anō hoki ki ngā āhuatanga o te parahi. Hei tauira, he pai rawa te kawe hiko me te ngāwari o te tango. Ki te whakatauritea ki pahuka nikara, he iti ake ngā utu whakaputa me te whānui ake o te pūmanawa tono mō te pahuka parahi. Heoi, nā te mea kua riro mai ngā āhuatanga o te parahi, he iti te ātete o te pahuka parahi me te parahi ki te waikura. Kei raro nei, ka whakamāramahia e mātou ngā tukanga whakaputa me ngā tikanga mō te pahuka parahi:

1. Paura Tikanga Whakarewa
Ko tēnei tikanga he tāpiri tonu i ngā kaipupuku huka ki te paura parahi. Kia oti te whakapūkara, ka memeha haere ngā kaipupuku huka, ka waiho ngā pūwero hei hanga i te parahi pupuhi.

2. Tikanga Whakatakotoranga Hikohiko
Ko te parahi pahuka i hangaia mā tēnei tukanga he āhua ōrite, ā, he tata ki te 95% te pore, nō reira he pai mō te hanga konganuku pahuka.

3. Te tukanga whakamakuku-whakaiti
Ki te whakaritea ki ngā tikanga e rua o mua, he tino uaua tēnei huarahi. Tuatahi, ka whakaranua te paura parahi hikohiko, ngā paura konutai hauota, me ngā momo tāpiringa. Kātahi ka pēhia te ranunga kia rite ki te konganuku matomato. Ka whakakāhia tēnei konganuku matomato ki roto i te hau argon, ā, ka whakarewahia te hua ki roto i te kaukau wai wera e rere ana. I muri i te whakarewanga, ka horoia te rauemi ki te kaukau ultrasonic me te horoi acetone. Whai muri i te horoinga, ka whakamarokehia kia puta ai te hanganga tuwhera. Heoi, ko te ōwehenga porosity o tēnei tikanga he 50-81% noa iho, me te rahi o te pore toharite mai i te 0.2 ki te 4 mm.

I tēnei wā, ko te nuinga pahuka parahi Ko te nuinga o te wā, ko ngā tikanga e toru o runga ake nei te whakamahinga matua o te mahi whakaputa. Ko te mahi whakarewa paura me te whakatakotoranga hikohiko ngā tikanga e whakamahia whānuitia ana i roto i te tukanga hanga. Ahakoa he maha ngā painga me te whaihua o ngā konganuku pahuka, me ngā tirohanga whānui me ngā mara tono, ko te whakaiti i ngā utu hanga me te whakapai ake i ngā tukanga hanga kua noho hei wero pūtaiao e hiahia ana kia whakatauhia.
