Kugadzira tekinoroji yegraphite-silicon carbide crucible

The raw material kuumbwa of graphite-silicon carbide cruciblesmusanganiswa wakanyatsorongeka wezvinhu zvakasiyana-siyana, chimwe nechimwe chichibatsira kune zvakasiyana-siyana zvechigadzirwa chekupedzisira. Inoumbwa neflake graphite, silicon carbide, elemental silicon poda, boron carbide poda uye ivhu, huremu hwezana hwezvinhu izvi zvakabikwa hunoita basa rakakosha pakuona zvimiro zvecrucible.

Iyo yekugadzira maitiro e graphite-silicon carbide crucibles inoteedzana nhanho dzeunyanzvi dzinovimbisa kunaka uye kuvimbika kwechigadzirwa chekupedzisira. Izvo zvigadzirwa zvinotanga zvakasanganiswa zvakaenzana kuti zvigadzire slurry inokwanisa, iyo inozoiswa muforoma uye nekutsikirirwa kuita chimiro uchishandisa isostatic press. Iyo inoguma isina chinhu inozoomeswa uye yakaputirwa neinodzivirira glaze, iyo inozove oxidized uye yakanyungudutswa mugirazi glaze kuburikidza neyakashama yekupfura maitiro. Chigadzirwa chakapedzwa chinozoongororwa uye choonekwa chagadzirira kushandiswa.

Chii chakasiyana pamusoro peiyi nzira yekugadzira iri nyore uye kuita kwakanakisa kwezvinokonzeresa crucibles. Iyo crucible ine yunifomu mameseji, yakakwira density, yakaderera porosity, inokurumidza thermal conductivity uye yakasimba corrosion resistance. Unhu uhwu hunoita kuti zvive zvakanaka kune zvakasiyana-siyana zvekushandisa, kunyanya mumaindasitiri umo kupisa kwakanyanya uye makemikari ane hutsinye akajairika.

Chimwe chinhu chinocherechedzwa chekugadzirwa kwevhu ndiko kushandiswa kwevhu sechisungirirwa. Sarudzo iyi inoshandisa chinangwa chehuviri sezvo isingangobatsiri kuita kunodiwa kweiyo crucible asi zvakare inoderedza kunetseka kwezvakatipoteredza. Iyi nzira inoshandisa ivhu sebhainda kudzivirira kuora uye kusunungurwa kwezvinhu zvinokuvadza zvakadai se phenolic resin kana tar, izvo zvingangobudisa utsi hunokuvadza neguruva panguva yekupisa uye kusvibisa nharaunda.

Muchidimbu, kuumbwa kwezvinhu zvakasvibirira uye maitiro ekugadzira graphite silicon carbide crucible inoratidza kuwirirana kubatanidzwa kwesainzi uye tekinoroji uye kuziva kwezvakatipoteredza. Zvigadzirwa zvinoguma zvinoratidza huchenjeri hwemaitiro emazuva ano ekugadzira, kupa mhinduro dzakavimbika uye dzakagadzikana kune maindasitiri anoda crucibles yepamusoro.
