Mumakore achangopfuura, indasitiri ye graphite mold yakagadzirwa nekusvetuka uye miganhu, uye makanda akagadzirirwa ari nyore kuumba, emhando yepamusoro, uye hapana chakasara mukukanda pachako. Kuti usangane nehunhu huri pamusoro, mold ine chikero graphite inoda kusarudza kodzero yekugadzirisa, nhasi Furuite graphite xiaobian ichakuudza nezve hunhu hwe mold ine scale graphite:
Hunhu hweflake graphite yekuumbwa (FIG. 1)
Kutanga, iyo yekupisa conduction coefficient ye mold flake graphite yakakwirira. Iko kutonhora kunokurumidza uye kukanda kunogona kukurumidza kubviswa uchishandisa graphite molds.
Vaviri, neimwe mechanical simba. Kana tembiricha yekukanda yakakwira, mold inofanirwa kuchengetedza chimiro chemukati, kuitira kuti kukanda kugone kuumbwa zvakanaka.
Tatu, kupisa kwekuwedzera kweiyo coefficient idiki, kupisa kwekudzivirira kukanganisa kuita kwakasimba. Iyo mold chimiro uye saizi shanduko idiki kana ichidziya uye yakatonhodzwa, saka zviri nyore kuchengetedza iyo chaiyo yekukanda.
Chechina, ita zvakanaka machining performance.
shanu, graphite oxide zvakananga kupinda gasi volatilization, workpiece haigoni kusiya chero zvakasara.
