Umuyoboro wa keramike wa Silicon Carbide udashobora kwambarwa
Ibara rya karubide ya silikoni: Ubukomere bwa Moh ni 9.0 ~ 9.2, bufite ubudahangarwa bwiza bwo kwangirika no kwangirika, burwanya kwangirika no kurwanya oxidation. Bufite imbaraga zikubye inshuro 4 kugeza kuri 5 kurusha nitride bonded silicon carbide. Igihe cyo gukora ni inshuro 7 kugeza ku 10 ugereranyije n'ibikoresho bya alumina. MOR ya RBSiC ikubye inshuro 5 kugeza kuri 7 ugereranyije na SNBSC, ishobora gukoreshwa mu miterere igoye cyane.
Ubudahangarwa bwa silicon carbide, ikorwa muri silicon carbide na karuboni ku bushyuhe bwinshi, ikoreshwa mu bwoko bwa silicon carbide. Ibice bya silicon carbide birwanya kwangirika bikoreshwa cyane mu gucukura, gusya amabuye, gusuzuma no gutwara ibintu byangiritse cyane, amazi yangiza cyane, kandi bikwiranye cyane n'ibikoresho bya mekanike bifite imiterere myiza kandi ifunga, nka pompe y'umuvuduko mwinshi, pompe ya magnetic nibindi. Ni ubwoko bushya bw'ibikoresho birwanya kwangirika. Silicon carbide irwanya kwangirika ifite imiterere yo gukomera cyane, kudahangarwa cyane, kudahangarwa cyane, kudahangarwa cyane, kudahangarwa cyane, kudahangarwa cyane, kudahangarwa cyane, kudahangarwa cyane n'ubushyuhe bwinshi, kudahangarwa cyane n'aside na alkali corruption nibindi, kandi ubuzima nyakuri bwa polyurethane buruta inshuro zirenga 6. Ikwiriye cyane cyane mu gukora mu byiciro, mu gushyira hamwe no kubura amazi mu bikoresho bikomeye byoroshye kandi bifite ibara ry'umukara, yakoreshejwe neza mu birombe byinshi. Isosiyete yacu ni uruganda rw'abahanga mu gutanga ibikoresho bya ceramic birwanya kwangirika bya silicon carbide, ubukomere bwa kabiri nyuma ya diyama, ifite ubushobozi bwo kwangirika cyane, kandi imara igihe kirekire. Umuyoboro n'inkokora birwanya kwangirika byakozwe mu mwenda urwanya kwangirika wa silicon carbide, uburebure bwawo bwa ceramic ni 6-35mm, imiterere ni iyo gushyiraho. Umuyoboro wa ceramic urimo gucukurwa mu muyoboro w'icyuma ujyanye nawo, hamwe na kole hagati. Imiyoboro ya ceramic irwanya kwambara ifite imiterere ikurikira ugereranije n'imiyoboro y'amabuye yakoreshejwe mbere, imiyoboro y'icyuma idapfa kwambara n'imiyoboro ya ceramic ivanze.
Karubide ya silikoni iboheshejwe na reaction (RBSC) ifite ubushobozi bwo kudashira neza, ifite ubushobozi bwo kuvura ubushyuhe bwinshi, isuri nziza no kudashira, iyi miterere ishobora gukoreshwa mu bintu bitandukanye nko mu miyoboro y'amazi, inkokora ya keramike, imiyoboro ikoresha spray, imiyoboro ikoresha amashanyarazi n'ibice bya hydrocyclone.
Imitako ya ZPC iraramba cyane kurusha imitako ya tile n'iya icyuma. Ibumba rya ZPC silicon carbide rirwanya ubushyuhe n'ubukonje, bigatuma igihe cyo kuyikoresha kigabanuka kandi kikagabanuka.
Ceramic ya silicion carbide ifatanye n'ibice (RBSIC) ni ibikoresho byiza cyane birwanya kwangirika, kandi bikwiriye cyane cyane mu gukora uduce duto cyane, uduce duto, gushyira mu byiciro, gucumba, amazi n'ibindi bikorwa. Bitewe n'imiterere yavuzwe haruguru,Umuyoboro wa karubide ya silikoni ya RBSiC / SiSiCishobora kurinda neza igice kwangirika no gushyuha cyane kugira ngo yongere igihe cyo gukora ibikoresho.

Imiterere y'imikorere y'umuyoboro wa keramik udapfa kwangirika wa silikoni
Ibiranga karubide ya silikoni bisanzwe birimo:
- Ubucucike buke
- Ingufu nyinshi
- Ingufu nziza ku bushyuhe buri hejuru (Ifite ingaruka ku buryo bworoshye)
- Ubudahangarwa bw'umwuka (Ifite ingaruka ku buryo bwo gukora ogisijeni)
- Ubudahangarwa bwiza cyane bw'ubushyuhe
- Ubukomere bwinshi n'ubudahangarwa bwo kwangirika

Inganda z'ibyuma n'amashanyarazi: Impamvu izi nganda zombi zihujwe ahanini ni uko inganda zombi zifite
Shandong Zhongpeng Special Ceramics Co., Ltd ni imwe mu mashami manini ya silicon carbide ceramic mu Bushinwa. SiC technical ceramic: Ubukana bwa Moh ni 9 (Ubukana bwa Moh bushya ni 13), bufite ubudahangarwa bwiza bwo kwangirika no kwangirika, ubukana bwiza bwo kwangirika no kurwanya oxidation. Igihe cy'akazi k'ibicuruzwa bya SiC ni inshuro 4 kugeza kuri 5 ugereranyije n'ibikoresho bya alumina 92%. MOR ya RBSiC ikubye inshuro 5 kugeza kuri 7 ugereranyije na SNBSC, ishobora gukoreshwa mu miterere igoye cyane. Uburyo bwo gutanga ibiciro ni bwihuse, gutanga ibintu ni uko byasezeranijwe kandi ubwiza ni ubwa mbere. Buri gihe dukomeza guhangana n'intego zacu kandi tugasubiza imitima yacu kuri sosiyete.
