Mefuta ea BoitšoaroBonded Silicone Carbide (RBSiC/SiSiC)
Hajoale, ho na le palo e kholo ea baetsi ba lihlahisoa ho fana ka lihlahisoa tsa Reaction Bonded SIC ho liindasteri tse fapaneng. Shandong Zhongpeng Special Ceramics Co., Ltd e lokela ho ba e mong oa barekisi ba molemo ka ho fetisisa ba nang le lihlahisoa tse fapaneng tsa Reaction Bonded SIC, tse kang Nozzle le tse ling tse matla a Motlakase, ceramics, kiln, tšepe le tšepe, morafo, mashala, alumina, petroleum, lik'hemik'hale. , desulphurization e metsi, tlhahiso ea mechine, le liindasteri tse ling tse khethehileng lefatšeng.
Reaction Bonded SIC e ka aroloa kakarabelo-bond silicon carbidelesilicon carbide e entsoeng ka karabelo, ho latela hore na sekheo se qalang se na le likaroloana tsa silicon carbide.
silicon carbide e kopantsoeng le reaction
Reaction-bonded silicon carbide e bua ka mokhoa oa ho theha motsoako oa silicon carbide. Ke boemong boo sekheo se qalang se nang le phofo ea silicon carbide. Ts'ebetsong ea karabelo, khabone le silicon li etsa karolo e ncha ea silicon carbide ebe li kopana le silicon carbide ea mantlha. Mokhoa oa ho lokisa o tjena, e leng mokhoa o sebelisoang hangata:
Ho kopanya silicon carbide phofo, carbon powder le organic binder;
Ho etsa motsoako o omileng le o omisitsoeng;
Qetellong, ho fumana silicon carbide e kopantsoeng le karabelo ka ho kenella ha silicon.
silicon carbide e hlahisoang ke mokhoa ona hangata e na le lijo-thollo tse mahoashe tsa silicon carbide crystal le litaba tse phahameng tsa silicon ea mahala. Leha ho le joalo, mokhoa ona o na le mokhoa o bonolo le litšenyehelo tse tlaase. Hajoale,
Silicon carbide e entsoeng ka ketso
Sekheo se qalang sa silicon carbide se entsoeng ka karabelo se na le carbide feela. Sekheo se qalang sa carbon porous se sebetsa ka silicon kapa alloy ea silicon ho lokisa thepa ea silicon carbide composite. Ts'ebetso ena e qapiloe pele ke Hucke. Mokhoa oa Hucke o boetse o na le mathata. Mokhoa oa eona oa ho lokisetsa o rarahane haholoanyane. Litsenyehelo tsa mokhoa ona li phahame. Ka nako e ts'oanang, khase e ngata e fetoha nakong ea ho phatloha ha mocheso. Sena se tla etsa hore ho be bonolo ho phatloha ha china. Ka hona, mokhoa ona o thata haholo ho hlahisa lihlahisoa tse kholo.
Ho phaella moo, coke ea petroleum e sebelisoa e le lisebelisoa tse tala ho lokisa li-slabs tsohle tsa carbon, ebe ho thehoa silicon carbide. Leha ho le joalo, thepa ea thepa e lokiselitsoeng e batla e le tlaase. Matla a eona hangata a tlase ho 400mpa. Ho tšoana ha silicon carbide e fumanoeng ha ho ntle. Ka lebaka la theko e tlaase ea petroleum coke, theko ea mokhoa ona e batla e le tlaase.
Summary
Ha ho bapisoa le mekhoa e meng ea ho lokisa ea silicon carbide ceramics, reaction bonded method e na le melemo ea eona e ikhethang. Hajoale, lipatlisiso sebakeng sena li shebane haholo le boithuto ba ts'ebetso ea sintering le sebopeho sa sebopeho le thepa ea lihlahisoa. Leha ho le joalo, liphuputso tse mabapi le ho etsa lintho tse se nang letho li batla li fokola. Leha ho na le lithuto tse ngata mabapi le mochini oa karabelo lipakeng tsa tsona, ho na le lithuto tse fokolang mabapi le kinetics ea permeability, mochini oa karabelo le sebopeho sa karolo ea lisebelisoa tsa tšebetso ea alloying. Ho na le lithuto tse 'maloa mabapi le ho lokisoa ha thepa e nang le thepa le meaho e laolehang ka ho kopanya ha silicon le lisebelisoa tse ling. Lintlha tsena li ntse li hloka ho ithutoa.
