Graphite Carbon Cruciblematurusi anowanzo shandiswa mukunyungudutsa simbi, marabhoritari kunyorera, uye mamwe epamusoro-tembiricha ekurapa maitiro. Ivo vane yakanakisa yepamusoro-tembiricha kugadzikana uye yekupisa conductivity, zvichiita kuti ive yakakurumbira mune izvi zvinoshandiswa. Ichi chinyorwa chichaongorora maitiro ekugadziraCarbon Graphite Crucible,kubva pakusarudzwa kwezvinhu zvakasvibirira kusvika pakugadzirwa kwechigadzirwa chekupedzisira.
Danho 1: Sarudza yakakodzera graphite zvinhu
Nhanho yekutanga mukugadzira girafu crucible ndeyekusarudza yakakodzera graphite zvinhu. Graphite crucibles anowanzo kugadzirwa echisikigo kana artificial graphite. Heano zvimwe zvinhu zvekufunga nezvazvo pakusarudza graphite zvinhu:
1. Kuchena:
Kuchena kwegraphite kwakakosha pakuita kweiyo crucible. Yakakwirira kuchena graphite crucibles inogona kushanda yakadzikama pane yakakwirira tembiricha uye haisi nyore kukanganiswa nemakemikari kuita. Naizvozvo, kugadzira emhando yepamusoro magirafu crucibles kazhinji kunoda kushandiswa kwezvakanyanya kuchena magirafu zvinhu.
2. Mamiriro:
Chimiro cheGraphite Lined Crucible zvakare chinhu chakakosha. Fine grained graphite inowanzo shandiswa kugadzira mukati mecrucibles, ukuwo coarser grained graphite inoshandiswa kugadzira goko rekunze. Ichi chimiro chinogona kupa chinodiwa kupisa kupisa uye kupisa conductivity ye crucible.
3. Thermal conductivity:
Graphite yakanakisa yekupisa yekupisa zvinhu, ndicho chimwe chezvikonzero nei graphite crucibles ichishandiswa zvakanyanya mukupisa-kupisa kwekushandisa. Kusarudza magirafu zvinhu zvine high thermal conductivity zvinogona kuvandudza kupisa uye kutonhora kwemazinga ecrucible.
4. Corrosion resistance:
Zvichienderana nemaitiro echinhu chiri kugadziriswa, dzimwe nguva zvinodikanwa kusarudza graphite zvinhu zvine corrosion resistance. Semuenzaniso, macrucibles anobata acidic kana alkaline zvinhu zvinowanzoda graphite ine corrosion resistance.
Danho 2: Gadzirira zvinyorwa zve graphite zvepakutanga
Kana chinhu chakakodzera chegirafu chasarudzwa, danho rinotevera nderokugadzirira girafu yepakutanga kuita chimiro chechidimbu. Iyi nzira inowanzobatanidza matanho anotevera:
1. Kupwanya:
Iyo yepakutanga graphite zvinhu kazhinji yakakura uye inoda kudzvanywa kuita zvidimbu zvidiki kuti zvizogadziriswa. Izvi zvinogona kuwanikwa kuburikidza nemichina yekupwanya kana nzira dzemakemikari.
2. Kusanganisa nekusunga:
Graphite particles kazhinji inoda kusanganiswa neanosunga maajenti kuti aumbe chimiro chepakutanga checrucible. Mabhainda anogona kuve maresin, zvinonamira, kana zvimwe zvinhu zvinoshandiswa kubatanidza magirafu zvimedu kuchengetedza chimiro chakasimba mumatanho anotevera.
3. Kudzvinyirira:
Iyo yakasanganiswa graphite uye binder kazhinji inoda kudzvanywa muchimiro checrucible pasi pekushisa kwakanyanya uye kumanikidzwa. Iyi nhanho inowanzopedzwa uchishandisa yakakosha crucible mold uye press.
4. Kuomesa:
Iyo yakatsikirirwa crucible inowanzoda kuomeswa kuti ibvise unyoro uye zvimwe zvinonyungudutsa kubva kune inosunga. Iyi nhanho inogona kuitwa pane tembiricha yakapfava kudzivirira deformation kana kuputika kwecrucible.
Nhanho 3: Sintering uye kugadzirisa
Kana iyo yekutanga crucible yagadzirwa, sintering uye nzira dzekurapa dzinofanirwa kuitwa kuti ive nechokwadi chekuti crucible ine kuita kunodiwa. Iyi nzira inowanzobatanidza matanho anotevera:
1. Sintering:
Iyo yepakutanga Crucible inowanzoda kunyungudutswa pakupisa kwakanyanya kuita kuti magirafu zvimedu zvibatane zvakanyanya uye kuvandudza densi uye simba reiyo crucible. Iyi nhanho inowanzoitwa pasi pe nitrogen kana inert atmosphere kudzivirira oxidation.
2. Kurapwa kwepamusoro:
Iyo yemukati uye yekunze nzvimbo dzecrucibles kazhinji inoda kurapwa kwakakosha kuti vavandudze mashandiro avo. Mamiriro emukati angada kupfekedzwa kana kupfekedzwa kuti kuwedzere kusaita ngura kana kunatsiridza kupisa. Nzvimbo yekunze ingada kukwenenzverwa kana kukwenenzverwa kuti uwane nzvimbo yakatsetseka.
3. Kuongorora uye kutonga kwehutano:
Kuongorora kwakasimba uye kutonga kwemhando kunofanirwa kuitwa panguva yekugadzira kuti ive nechokwadi chekuti crucible inosangana nezvinodiwa. Izvi zvinosanganisira kutarisa saizi, density, thermal conductivity, uye corrosion resistance yecrucible.
Nhanho 4: Yekupedzisira kugadzirisa uye yapera zvigadzirwa
Chekupedzisira, iyo crucible yakagadzirirwa kuburikidza nematanho ari pamusoro inogona kuiswa pasi pekupedzisira kugadziriswa kuti uwane chigadzirwa chakapedzwa. Izvi zvinosanganisira kucheka mipendero ye crucible, kuve nechokwadi chezviyero zvakaringana, uye kuita chekupedzisira chemhando yemhando. Kana iyo crucible ichipfuura kudzora kwemhando, inogona kuiswa uye kugoverwa kune vatengi.
Muchidimbu, kugadzira graphite crucibles inzira yakaoma inoda hunyanzvi hwekugadzira uye hunyanzvi hwemhando yepamusoro. Nekusarudza zvinhu zvakakodzera, kugadzirira mbishi, sintering uye kugadzirisa, uye kushandisa yakasimba yemhando yekudzora, yakakwirira-inoshanda graphite crucibles inogona kugadzirwa kune akasiyana emhando yekupisa. Kugadzirwa kwemagraphite crucibles chikamu chakakosha chemunda weinjiniya yegraphite, ichipa chishandiso chakakosha kune akasiyana maindasitiri nesainzi mashandisirwo.
