Huānga Whakamahana Whakamahana Graphite Paninga SiC Teitei Maamaa Ritenga

Te Huānga Whakamahana Graphite Paninga SiC Teitei Teitei Ritenga Whakaahua Matua

Whakaahuatanga Poto:

Ko te whakamahana karāpiti he momo rauemi whakamahana hiko e whakaputa ana i te wera mā te whakamahana i te rauemi karāpiti mā te hiko, he mea hanga i te karāpiti me te uku. Ka taea e tōna hanganga ngaru te whakamarara i te wera, ā, he whānuitia te whakamahinga i roto i ngā ahumahi, ngā hanganga, ngā ahuwhenua me ngā mahi o ia rā. Nā te pai o te kawe wera me te pumau o te pāmahana, he whānuitia te whakamahinga o te huānga whakamahana karāpiti i roto i ngā ahumahi.

Ngā Tohu Hua

Ngā āhuatanga matua o te whakamahana graphite:

1. te ōritetanga o te hanganga whakamahana.

2. he pai te kawe hiko me te kawenga hiko teitei.

3. ātete ki te waikura.

4. te kore e taea te waikura.

5. te parakore matū teitei.

6. kaha ā-mīhini teitei.

Ko te painga he penapena pūngao, he nui te utu, ā, he iti te tiaki. Ka taea e mātou te whakaputa i te oko karāpeti ārai-waikura me te roa o te ora, te pokepoke karāpeti me ngā wāhanga katoa o te whakamahana karāpeti.
