Ubwoko bwa Karubide ya Silicone Iboheshejwe na Reaction (RBSiC/SiSiC)

Ubwoko bw'IbibazoKarubide ya Silicone Ifatanye (RBSiC/SiSiC)

Kuri ubu, hari inganda nyinshi zitanga ibicuruzwa bya Reaction Bonded SIC ku nganda zitandukanye. Shandong Zhongpeng Special Ceramics Co., Ltd igomba kuba imwe mu nganda nziza zitanga ibicuruzwa bitandukanye bya Reaction Bonded SIC, nka Nozzle n'izindi mu bijyanye n'amashanyarazi, ibumba, itanura, icyuma n'ibyuma, ubucukuzi bw'amabuye y'agaciro, amakara, alumina, peteroli, imiti, desulphurization y'amazi, gukora imashini, n'izindi nganda zidasanzwe ku isi.

Reaction Bonded SIC ishobora kugabanywamo ibicekarubide ya silikoni ifatanye n'ibisubizonakarubide ya silikoni ikozwe mu buryo bw'ingufu, hakurikijwe niba ahantu habanza hari uduce twa silikoni karubide.

Karubide ya silikoni ifatanye n'ibisubizo

Karuboni ya silikoni ifatanye na reaction-bonded yerekeza ku buryo bwo gukora silicon carbide composite. Ni mu gihe ahantu hatangira ubusa harimo ifu ya silikoni carbide. Mu buryo bwo gukora reaction, karuboni na silikoni bikora kugira ngo bikore silicon carbide nshya kandi bihuzwe na silikoni carbide y'umwimerere. Uburyo bwo gutegura ni ubu bukurikira, ari na bwo buryo bukunze gukoreshwa:

Kuvanga ifu ya karuboni ya silikoni, ifu ya karuboni n'icyuma gifunga ibintu kikomoka ku bidukikije;

Gukora uruvange rwumye kandi rukavamo umugozi;

Amaherezo, kubona karubide ya silikoni ifatanye n'ibisubizo binyuze mu kwinjira kwa silikoni.

Karubide ya silikoni ikozwe muri ubu buryo muri rusange igizwe n'ibinyampeke bya silikoni ya silikoni ikoze mu buryo bwa "coarse silicon carbide crystal" hamwe n'ingano nini ya silikoni ikozwe mu buryo bwa "free silicon". Ariko, ubu buryo bufite inzira yoroshye kandi buhendutse. Kuri ubu,

Karubide ya silikoni ikozwe mu buryo bwa reaction

Igice cyo gutangira cya karuboni ya silikoni ikozwe mu buryo bw'ingufu kirimo karuboni gusa. Igice cyo gutangira cya karuboni ifite imyenge gikoreshwa na silikoni cyangwa aloyi ya silikoni kugira ngo hategurwe ibikoresho bya silikoni bya karuboni. Ubu buryo bwabanje kuvumburwa na Hucke. Uburyo bwa Hucke nabwo bufite ingorane zabwo. Uburyo bwo kubutegura buragoye cyane. Igiciro cy'ubu buryo kiri hejuru. Muri icyo gihe, gazi nyinshi irahinduka mu gihe cy'ubushyuhe bukabije. Ibi bizatuma Ubushinwa burushaho gucika. Kubwibyo, ubu buryo buragoye cyane gukora ibicuruzwa binini.

Byongeye kandi, peteroli coke ikoreshwa nk'ibikoresho fatizo mu gutegura slabs zose za karuboni, hanyuma hagakorwa silicon carbide. Ariko, imiterere y'ibikoresho byateguwe ni mike cyane. Ubusanzwe imbaraga zayo ziba ziri munsi ya 400mpa. Ubusanzwe silicon carbide iboneka ntabwo ari nziza. Kubera ko igiciro cya peteroli coke ari gito, igiciro cy'ubu buryo ni gito cyane.

Sincamake

Ugereranyije n'ubundi buryo bwo gutegura silicon carbide ceramics, uburyo bwo guhuza reaction bufite ibyiza byabwo bidasanzwe. Kuri ubu, ubushakashatsi muri uru rwego bwibanda cyane ku kwiga inzira yo gusya no kugena imiterere n'imiterere y'ibicuruzwa. Ariko, ubushakashatsi ku gukora ubusa ni buke cyane. Nubwo hari ubushakashatsi bwinshi ku buryo bwo guhuza reaction hagati yabyo, hari ubushakashatsi buke ku buryo bwo guhuza permeability, uburyo bwo guhuza reaction n'imiterere y'igice cy'ibikoresho byo guhuza alloying. Hari ubushakashatsi buke ku gutegura ibikoresho bifite imiterere n'imiterere bishobora kugenzurwa binyuze mu guhuza silicon infiltration n'ibindi bikoresho. Ibi bice biracyakeneye kwigwa.
