Copper graphite

Tsanangudzo Pfupi:

Copper graphite chinhu chinoumbwa chine mhangura hupfu uye graphite, iyo inonyanya kushandiswa sechinhu chekugadzira conductive uye thermal conductive zvikamu. Izvi zvinotevera kutsanangurwa kwechigadzirwa chemhangura graphite, kusanganisira maitiro ayo, kushandiswa, kugadzira maitiro, zvinodiwa zvemhando, nezvimwe.

Hunhu

1. Good conductivity: copper graphite ine conductivity yakaisvonaka, uye resistivity yayo inenge 30% yemhangura yakachena, inogona kushandiswa sechinhu chinogadzirisa.

2. Good thermal conductivity: copper graphite ine yakanakisa thermal conductivity, uye yayo thermal conductivity inenge 3 nguva yemhangura, iyo inogona kushandiswa sechinhu chinopisa chekugadzirisa.

3. Pfeka kuramba uye kusagadzikana kwekuora: mhangura graphite ine yakanakisa kupfeka kusagadzikana uye kushora kusagadzikana, uye inogona kushandiswa kugadzira mechanical zvikamu zvine tembiricha yakakwira, kudzvanywa kwakanyanya uye kumhanya kwakanyanya.

4. Zvakanaka machinability: mhangura graphite inogona kushandiswa nyore nyore uye kuunganidzwa, uye inogona kushandiswa kugadzira zvikamu zvemhando dzakasiyana-siyana.

Chinangwa

Iko kushandiswa kukuru kwecopper graphite kunosanganisira:

1. Kugadzira zvikamu zvinofambisa zvakadai semagetsi, mabhurashi, magetsi ekubatanidza, nezvimwewo

2. Gadzira kupisa conduction zvikamu senge kupisa conduction mudziyo uye radiator

3. Kugadzirwa kwezvisimbiso zvemakanika, mabheji uye zvimwe zvikamu zvisingapfekere

4. Kugadzira zvigadzirwa zvemhando yepamusoro senge zvigadzirwa zvemagetsi, semiconductor zvishandiso, maseru ezuva.

Manufacturing process

Iyo nzira yekugadzira yemhangura graphite iri nyore, kazhinji inosanganisira anotevera matanho:

1. Kugadzirira zvinhu: poda yemhangura uye graphite powder ichasanganiswa mune imwe chikamu, uye imwe chiyero chemafuta uye binder ichawedzerwa.

2. Kugadzirira kwemuviri wekuumba: dzvanya zvinhu zvakasanganiswa mumutumbi wekuumba wakakodzera kugadziriswa.

3. Kuomesa uye kugadzirisa: omesa kuumba, uye wozogadzirisa, zvakadai sekutendeuka, kugaya, kuchera, nezvimwe.

4. Sintering: sintering zvikamu zvakagadziriswa kuti zvigadzire yakasimba mhangura graphite zvinhu.

Hunhu hunodiwa

Izvo zvinodiwa zvemhando yecopper graphite zvinosanganisira zvinotevera zvinhu:

1. Mhedzisiro yemagetsi uye thermal conductivity ichasangana nezvinodiwa.

2. Hunhu hwekutaridzika huchave hwakasimba pasina kuputika kuri pachena, kubatanidzwa uye mabhubhu.

3. Kururama kwedimensional kuchasangana nezvinodiwa zvekugadzira mifananidzo.

4. Kusagadzikana kwekupfeka uye kusagadzikana kwekuora kuchasangana nezvinodiwa zvekushandisa.
