Isostatic graphite, inozivikanwawo sekuti isostatically yakaumbwa graphite, inoreva nzira iyo musanganiswa wemidziyo inotsikirirwa kuita rectangular kana denderedzwa blocks muhurongwa hunodaidzwa kuti cold isostatic pressing (CIP). Cold isostatic kudzvanya inzira yekugadzirisa zvinhu umo shanduko mukudzvinyirirwa kweyakavharirwa, incompressible fluid inotapurirwa zvisingaite kune imwe neimwe chikamu chemvura, kusanganisira pamusoro pemudziyo wayo.
Kuenzaniswa nemamwe matekiniki akadai seextrusion uye vibration kuumba, CIP tekinoroji inoburitsa yakanyanya isotropic synthetic graphite.Isostatic graphitezvakare kazhinji ine diki diki saizi yechero yakagadzirwa graphite (inoda kusvika 20 microns).
Kugadzira maitiro e isostatic graphite
Isostatic kudzvanya inzira yakawanda-nhanho inobvumira kuwana yakanyanyisa yunifomu mabhuroko ane anogara emuviri ma paramita muchikamu chese uye poindi.
Yakajairika zvimiro zve isostatic graphite:
• Kunyanya kupisa uye kusagadzikana kwemakemikari
• Excellent thermal shock resistance
• High magetsi conductivity
• High thermal conductivity
• Inowedzera simba nekuwedzera tembiricha
• Easy kugadzirisa
• Inogona kugadzirwa mukuchena kwakanyanya (<5 ppm)
Kugadzirwa kweisostatic graphite
1. Coke
Coke chikamu chinogadzirwa mumafuta ekunatsa nekudziya marasha akaomarara (600-1200 ° C). Maitiro acho anoitwa mumaovheni ecoke akanyatsogadzirwa achishandisa gasi rinopisa uye kushomeka kweokisijeni. Iine hukoshi hwepamusoro hwe calorific pane hwemazuva ose fossil marasha.
2. Kupwanya
Mushure mekutarisa iyo mbishi, inopwanyika kune imwe particle size. Michina yakakosha yekukuya zvinhu inotamisa hupfu hwakatsetseka hwemarasha hwakawanikwa mumabhegi akakosha uye woaisa zvichienderana nekukura kwechikamu.
Pitch
Izvi zvinobva pakubikwa kwemarasha akaomarara, kureva kugocha pa1000-1200°C pasina mhepo. Pitch imvura yakasviba yakasviba.
3. Kukanya
Mushure mekunge nzira yekukuya coke yapera, inosanganiswa nenamo. Zvose zviri zviviri zvakasanganiswa zvinosanganiswa pakupisa kwepamusoro kuitira kuti marasha anyunguduke uye asanganise nezvikamu zvecoke.
4. Second pulverization
Mushure mekusanganisa, mabhora madiki ekabhoni anoumbwa, ayo anofanirwa kugadzika zvakare kune akanyanya kunaka particles.
5. Isostatic pressing
Kana zvimedu zvakanaka zvehukuru hunodiwa zvagadzirwa, nhanho yekutsikirira inotevera. Iyo yakawanikwa poda inoiswa muhombe huru, zviyero zvaro zvinoenderana nehukuru hwekupedzisira block. Iyo kabhoni poda mu mold inoratidzwa kune yakakwira kudzvanywa (kupfuura 150 MPa), iyo inoshandisa simba rimwechete uye kumanikidza kune zvimedu, kuronga iwo symmetrically uye nokudaro kugoverwa zvakaenzana. Iyi nzira inobvumira kuwana yakafanana graphite parameters mu mold.
6. Carbonization
Nhanho inotevera uye yakareba (2-3 mwedzi) iri kubheka muchoto. Iyo isostatically yakadzvanywa zvinhu inoiswa muchoto chikuru, umo tembiricha inosvika 1000 ° C. Kuti udzivise chero kukanganisa kana kuputika, kutonhora muchoto kunogara kuchidzorwa. Mushure mekubika kwapera, chivharo chinosvika pakuoma kunodiwa.
7. Pitch Impregnation
Panguva ino, chivharo chinogona kuiswa nepitch uye kupiswa zvakare kuderedza porosity yayo. Kuisa pamuviri kunowanzoitwa nenamo ine viscosity yakaderera pane yenamo inoshandiswa sebhainda. Iyo yakaderera viscosity inodiwa kuzadza mapeji zvakanyatsojeka.
8. Graphitization
Panguva ino, matrix ecarbon atomu akarairwa uye shanduko kubva kucarbon kuenda kugraphite inonzi graphitization. Graphitization ndiko kudziyisa kwebhuroko rakagadzirwa kusvika pakupisa kunosvika 3000°C. Mushure me graphitization, kuwanda, magetsi conductivity, kupisa conductivity uye corrosion resistance inovandudzwa zvakanyanya, uye kugadzirisa kushanda kunovandudzwa zvakare.
9. Graphite Material
Mushure me graphitization, zvese zvivakwa zve graphite zvinofanirwa kutariswa - kusanganisira saizi yezviyo, density, kukotama uye kumanikidza simba.
10. Kugadzirisa
Kana zvinhu zvacho zvanyatsogadzirirwa uye kutariswa, zvinogona kugadzirwa zvinoenderana nemagwaro evatengi.
11. Kucheneswa
Kana isostatic graphite inoshandiswa mu semiconductor, single crystal silicon uye maatomu emagetsi emagetsi, kuchena kwepamusoro kunodiwa, saka tsvina yose inofanira kubviswa nemakemikari nzira. Maitiro ekubvisa tsvina yegraphite kuisa chigadzirwa chine graphiti muhalogen gasi uye kupisa kusvika 2000 ° C.
12. Kurapa kwepamusoro
Zvichienderana nekushandiswa kwe graphite, nzvimbo yaro inogona kuva pasi uye ine nzvimbo yakatsetseka.
13. Kutumira
Mushure mekugadzirisa kwekupedzisira, iyo yakapedzwa graphite data inoiswa uye inotumirwa kune mutengi.
Kuti uwane rumwe ruzivo nezve saizi iripo, isostatic graphite mamakisi uye mitengo, ndapota inzwa wakasununguka kutibata nesu. Mainjiniya edu achafara kukupa zano pazvinhu zvakakodzera uye kupindura mibvunzo yako yese.
