Manufacturing nagraphite isostatic
1. Koke
Coke wani sashi ne da ake samarwa a matatun mai ta hanyar dumama kwal mai ƙarfi (600-1200°C). Ana aiwatar da tsarin ne a cikin tanda na coke na musamman da aka kera ta amfani da iskar gas mai ƙonewa da ƙarancin iskar oxygen. Yana da ƙimar calorific mafi girma fiye da kwal ɗin burbushin al'ada.
2. Rushewa
Bayan an duba albarkatun kasa, sai a niƙa shi zuwa wani ƙayyadaddun ƙwayar ƙwayar cuta. Na'urori na musamman don niƙa kayan suna canja wurin foda mai kyau mai kyau da aka samu cikin jaka na musamman kuma a rarraba su bisa ga girman barbashi.
Fita
Wannan samfur ne na coking na kwal mai ƙarfi, watau gasa a 1000-1200 ° C ba tare da iska ba. Pitch ruwa ne mai yawa baƙar fata.
3. Kneading
Bayan an gama aikin niƙan coke, sai a haɗe shi da farar. Dukan kayan da aka yi amfani da su ana haɗe su a zafin jiki mai zafi ta yadda kwal ɗin zai iya narke kuma a haɗa su da ɓangarorin coke.
4. Na biyu taki
Bayan tsarin hadawa, an samar da ƙananan ƙwallo na carbon, waɗanda dole ne a sake ƙasa zuwa ɓangarorin masu kyau.
5. Isostatic latsawa
Da zarar an shirya barbashi masu kyau na girman da ake buƙata, matakin dannawa ya biyo baya. Ana sanya foda da aka samu a cikin manyan ƙira, wanda girmansa ya dace da girman toshe na ƙarshe. The carbon foda a cikin mold an fallasa zuwa babban matsa lamba (fiye da 150 MPa), wanda ya shafi wannan karfi da matsa lamba ga barbashi, shirya su symmetrically kuma ta haka ko'ina rarraba. Wannan hanya tana ba da damar samun sigogi iri ɗaya na graphite a ko'ina cikin ƙirar.
6. Carbonization
Mataki na gaba kuma mafi tsayi (watanni 2-3) yana yin burodi a cikin tanderu. Ana sanya kayan da aka matsa a cikin wani babban tanderu, inda zafin jiki ya kai 1000 ° C. Don guje wa kowane lahani ko fashe, ana sarrafa yawan zafin jiki a cikin tanderu. Bayan an gama yin burodi, toshe ya kai ga taurin da ake buƙata.
7. Ciwon ciki
A wannan mataki, toshe na iya zama ciki da farar ƙasa kuma a sake ƙone shi don rage girmansa. Yawanci ana aiwatar da ciki tare da farar da ke da ƙananan danko fiye da farar da ake amfani da shi azaman ɗaure. Ana buƙatar ƙananan danko don cike giɓi daidai.
8. Zane-zane
A wannan mataki, an ba da umarnin matrix na carbon atom kuma tsarin canji daga carbon zuwa graphite ana kiransa graphitization. Graphitization shine dumama tubalan da aka samar zuwa zafin jiki na kusan 3000°C. Bayan graphitization, da yawa, lantarki conductivity, thermal conductivity da kuma lalata juriya suna da muhimmanci sosai inganta, da kuma aiki yadda ya dace.
9. Graphite Material
Bayan graphitization, duk kaddarorin na graphite dole ne a duba - ciki har da girman hatsi, yawa, lankwasawa da matsawa ƙarfi.
10. Gudanarwa
Da zarar an gama shirya kayan kuma an bincika, ana iya kera shi bisa ga takaddun abokin ciniki.
11. Tsarkakewa
Idan ana amfani da graphite isostatic a cikin semiconductor, silicon crystal guda ɗaya da masana'antar makamashin atomic, ana buƙatar tsafta mai ƙarfi, don haka dole ne a cire duk ƙazanta ta hanyoyin sinadarai. Tsarin al'ada don cire ƙazantattun graphite shine sanya samfurin da aka zana a cikin iskar halogen kuma a zafi shi zuwa kusan 2000 ° C.
12. Maganin saman
Dangane da aikace-aikacen graphite, samansa na iya zama ƙasa kuma yana da ƙasa mai santsi.
13. Shipping
Bayan aiki na ƙarshe, an tattara cikakkun bayanan graphite kuma an aika zuwa abokin ciniki.
Don ƙarin bayani kan samuwa masu girma dabam, isostatic graphite maki da farashin, da fatan za a ji kyauta don tuntuɓar mu. Injiniyoyin mu za su yi farin cikin ba ku shawara akan kayan da suka dace kuma su amsa duk tambayoyinku.
