Mhando dzeRectionBonded Silicone Carbide (RBSiC/SiSiC)
Parizvino, kune huwandu hukuru hwevagadziri kuti vape Reaction Bonded SIC zvigadzirwa kune akasiyana maindasitiri. Shandong Zhongpeng Special Ceramics Co., Ltd inofanirwa kunge iri mumwe wevanonyanya kutengesa neakasiyana Reaction Bonded SIC zvigadzirwa, zvakaita seNozzle nezvimwe zviri mumagetsi eMagetsi, ceramics, kiln, iron nesimbi, mugodhi, marasha, alumina, peturu, kemikari. , wet desulphurization, kugadzira michina, uye mamwe maindasitiri akakosha munyika.
Iyo Reaction Bonded SIC inogona kukamurwa kuitareaction-bonded silicon carbideuyereaction-yakagadzirwa silicon carbide, zvichienderana nekuti iyo yekutanga isina chinhu ine silicon carbide particles.
Reaction-bonded silicon carbide
Reaction-bonded silicon carbide inoreva maitiro ekugadzira silicon carbide composite. Iri mumamiriro ezvinhu kuti iyo yekutanga isina chinhu ine silicon carbide poda. Mukuita maitiro, kabhoni nesilicon zvinobata kuumba nyowani silicon carbide chikamu uye kusanganisa neyekutanga silicon carbide. Nzira yekugadzirira ndeyotevera, inova nzira inowanzoshandiswa:
Kusanganisa silicon carbide poda, kabhoni poda uye organic binder;
Kuumba musanganiswa wakaoma uye wakasungirirwa;
Pakupedzisira, kuwana reaction-yakasungirirwa silicon carbide kuburikidza nesilicon infiltration.
Iyo reaction-yakasungirirwa silicon carbide inogadzirwa neiyi nzira inowanzo ine coarse silicon carbide crystal tsanga uye yakakwira yemahara silicon. Zvisinei, iyi nzira ine nzira iri nyore uye yakaderera mutengo. Parizvino,
Reaction-yakaumbwa silicon carbide
Iyo yekutanga blank ye reaction-yakaumbwa silicon carbide chete ine carbide. Iyo yekutanga blank ye porous kabhoni inobatwa nesilicon kana silicon alloy kugadzirira silicon carbide composite zvinhu. Iyi nzira yakatanga kugadzirwa naHucke. Nzira yeHucke inewo zvipingamupinyi zvayo. Nzira yekugadzirira kwayo yakanyanya kuoma. Mutengo weiyi nzira yakakwirira. Panguva imwecheteyo, huwandu hwakawanda hwegesi hunoshanduka panguva yekupisa kwekushisa. Izvi zvinotungamira kune nyore kupaza kwechina. Nokudaro, nzira iyi inonyanya kuoma kugadzira zvigadzirwa zvakakura.
Uye zvakare, petroleum coke inoshandiswa seyakabikwa kugadzira ese kabhoni slabs, uye ipapo silicon carbide inoumbwa. Zvisinei, zvinhu zvezvinhu zvakagadzirirwa zvakaderera. Simba rayo kazhinji rakaderera pane 400mpa. Kufanana kweiyo yakawanikwa silicon carbide haina kunaka. Nekuda kwemutengo wakaderera wepetroleum coke, mutengo weiyi nzira wakaderera.
Summary
Kuenzaniswa nedzimwe nzira dzekugadzirira dzesilicon carbide ceramics, reaction bonded nzira ine mabhenefiti ayo akasiyana. Parizvino, tsvagiridzo munharaunda ino inonyanya kutarisisa pakudzidza kwekuita sintering uye kuratidzwa kwechimiro uye zvimiro zvezvigadzirwa. Nekudaro, tsvakiridzo yekuumbwa isina chinhu ishoma. Kunyangwe paine zvidzidzo zvakawanda pamusoro pemaitiro ekuita pakati pavo, pane zvishoma zvidzidzo zvepermeability kinetics, maitiro ekuita uye kuumbwa kwechikamu chechinhu cheiyo alloying process. Pane zvishoma zvidzidzo pamusoro pekugadzirira kwezvinhu zvine controllable zvivakwa uye zvimiro nekubatanidzwa kwesilicon infiltration uye zvimwe zvinhu. Zvinhu izvi zvichiri kuda kudzidzwa.
