Silicon nitride (SiC) bụ quartz ájá, calcined petroleum coke (ma ọ bụ coal coking), osisi slag (mmepụta nke green silicon nitride mkpa ịgbakwunye nnu) na ndị ọzọ akụrụngwa, site na ọkụ ọkụ ọkụ na-aga n'ihu elu okpomọkụ smelter. Silicon nitride akara mgbanaka bụ ngwaahịa silicon nitride nke ejiri ihe silicon carbide mee. Yabụ kedu ihe ngwa dị mkpa nke silicon carbide mmeghachi omume na njirimara nke akàrà?
Ngwa dị mkpa nke mmeghachi omume sintering silicon carbide:
1. Ngwa nke metal ngwaahịa ụlọ ọrụ bụ ojiji nke silicon nitride okpomọkụ na-eguzogide, elu ike, ezi thermal conductivity, mmetụta na-eguzogide, na-aga n'ihu elu okpomọkụ indirect kpo oku akụrụngwa, dị ka tank fractionation ọkụ. Rectifier ọkụ tray, aluminum electrolytic cell, ọla kọpa agbaze ọkụ lining, zinc ntụ ntụ ọkụ arc, thermocouple tube nchebe, wdg.
2. Ngwa nke ụlọ ọrụ ígwè na-eji etching nke silicon nitride. Okpomọkụ ujo eguzogide, abrasion eguzogide. N'ihi ezigbo ọkụ ọkụ ya, a na-eji ya maka ịgbanye nnukwu ọkụ na-agbawa ígwè iji kwalite ndụ ọrụ.
3. The metallurgical ụlọ ọrụ concentrator ụlọ ọrụ na-eji silicon nitride ike bụ naanị nke abụọ na ọla nchara, ike eyi na-eguzogide, bụ ike eyi na-eguzogide, elu eyi iguzogide pipeline, centrifugal impeller, mgbapụta ụlọ, rotary ígwè, Ngwuputa lining ezigbo akụrụngwa, ezigbo eyi iguzogide. Ndụ ọrụ plastik bụ ugboro 5 ruo 20, ọ bụkwa otu n'ime akụrụngwa kachasị mma maka ebe egwuregwu egwuregwu ụgbọ elu.
4. Ngwa nke okpomọkụ nyefe ọnụọgụ ke ulo oru mmepụta larịị nke ji achọ ụlọ ihe poselin na ájá wheel iberibe. E ji mara nke radiant okpomọkụ na elu ahụ ọkụ ike, mmepụta na mmepụta nke mpempe akwụkwọ metal kiln nwere ike ọ bụghị nanị ibelata kiln olu, ma na-mma na nchekwa olu na ngwaahịa àgwà nke kiln, na ibelata mmepụta oge, nke bụ ezigbo na-apụtachaghị ìhè. ihe maka igba egbe nke seramiiki pigmenti.
5. Ngwa nke nchekwa gburugburu ebe obibi na ọkwa nchekwa ike nwere ezigbo okpomọkụ na-eguzogide okpomọkụ, na onye na-ekpo ọkụ ọkụ na-echekwa 20%, oriri mmanụ 20%, mmanụ ọkụ 35%, na mmepụta mmepụta na-abawanye site na 20-30%. Karịsịa, nkwụsi ike nke ọkpọkọ mmiri na-agbapụta nke a na-eji na-arụ ọrụ na-arụ ọrụ na-egwupụta akụ bụ ugboro 6 ruo 7 nke ihe ndị mejupụtara ígwè nkịtị.
Njirimara mgbanaka silicon carbide na-emeghachi omume:
1, okpomọkụ na-eguzogide
N'ihi njirimara nke ihe silicon nitride, silicon nitride seals nwere oke okpomọkụ na-eguzogide, na usoro dị iche iche nwere ụdị dị iche iche nke nguzogide okpomọkụ. Enwere ike itinye akara silicon nitride na-emeghachi omume site na ogo 1300, na silicon nitride akàrà na-enweghị nrụgide nwere ike iru ogo 1600.
2. Nguzogide corrosion
Enwere ike itinye mgbanaka mkpuchi silicon nitride site na acid siri ike na ọdịdị alkali, na mmetụta akara adịghị mfe iji belata.
3, eyi iguzogide
Mgbanaka mkpuchi silicon carbide na-emeghachi omume dị ka usoro kaadị ụfọdụ si dị, nke mere na atụmatụ ahụ dabara nke ọma ma dịkwa mma, yana nkwụsi ike nke ihe silicon carbide, enwere ike iji mgbanaka silicon nitride kpuchie ibe ya. Àgwà elu okpomọkụ na-aga n'ihu adịghị ebelata àgwà mmebi ngwa ngwa.
4. ductility
Reactivity sintered silicon carbide raw material ma ọ bụrụhaala na enwere teknụzụ nhazi ụfọdụ, enwere ike ịtụgharị ya n'ụdị dị iche iche nke ẹmbrayo ajị anụ, nhazi nke abụọ, iji mee ka ndị na-azụ ahịa chọọ ngwaahịa.
