Mhando dzeKuitaSilicone Carbide Yakabatana (RBSiC/SiSiC)

Parizvino, kune vagadziri vakawanda vanopa zvigadzirwa zveReaction Bonded SIC kumaindasitiri akasiyana. Shandong Zhongpeng Special Ceramics Co., Ltd inofanirwa kuve imwe yevatengesi vakanakisa vane zvigadzirwa zvakasiyana-siyana zveReaction Bonded SIC, zvakaita seNozzle nezvimwe mumagetsi, ceramics, kiln, iron and steel, mine, coal, alumina, peturu, chemical, wet desulphurization, manufacturing machinery, uye mamwe maindasitiri akakosha pasi rose.

Reaction Bonded SIC inogona kukamurwa kuitasilicon carbide yakabatana ne reaction-bondeduyesilicon carbide yakagadzirwa ne reaction, zvichienderana nekuti chigadziko chekutanga chine zvidimbu zvesilicon carbide here.

Kabhidhi yesilicon yakabatana neReaction-bonded

Silicon carbide ine reaction-bonded inoreva maitiro ekuumba silicon carbide composite. Zviri mumamiriro ezvinhu apo starting blank ine silicon carbide powder. Mukuita reaction, kabhoni nesilicon zvinopindura kuti zvigadzire silicon carbide phase itsva uye zvinosanganiswa nesilicon carbide yekutanga. Maitiro ekugadzirira ndeekuti, inova nzira inowanzoshandiswa:

Kusanganisa upfu hwesilicon carbide, upfu hwecarbon uye organic binder;

Kugadzira musanganiswa wacho wakaoma wobva wabviswa mabhondi;

Pakupedzisira, kuwana silicon carbide ine reaction-bonded kuburikidza nekupinda kwesilicon.

Iyo reaction-bonded silicon carbide inogadzirwa nenzira iyi inowanzo kuve ne coarse silicon carbide crystal grains uye huwandu hwakawanda hwe free silicon. Zvisinei, nzira iyi ine maitiro ari nyore uye inodhura zvishoma. Parizvino,

Silicon carbide yakagadzirwa ne reaction

Nzvimbo yekutanga yesilicon carbide yakagadzirwa ne reaction ine carbide chete. Nzvimbo yekutanga yecarbon ine porous inogadziriswa nesilicon kana silicon alloy kugadzira silicon carbide composite material. Maitiro aya akatanga kugadzirwa naHucke. Nzira yeHucke inewo matambudziko ayo. Maitiro ayo ekugadzirira akaomarara. Mutengo wenzira iyi wakakwira. Panguva imwe chete, gasi rakawanda rinoshanduka panguva yekupisa. Izvi zvinoita kuti China iparare zviri nyore. Nokudaro, nzira iyi yakaoma kugadzira zvigadzirwa zvakakura.

Pamusoro pezvo, petroleum coke inoshandiswa sezvinhu zvakabikwa kugadzira ma carbon slabs ese, uye silicon carbide inogadzirwa. Zvisinei, hunhu hwezvinhu zvakagadzirwa hwakaderera. Simba rayo rinowanzova pasi pe400mpa. Kufanana kwesilicon carbide yakawanikwa hakuna kunaka. Nekuda kwemutengo wakaderera wepetroleum coke, mutengo wenzira iyi wakaderera.

Sruzivo

Zvichienzaniswa nedzimwe nzira dzekugadzirira dze silicon carbide ceramics, nzira ye reaction bonded ine zvayakanakira zvakasiyana. Parizvino, tsvakiridzo munharaunda iyi inonyanya kutarisa pakudzidza maitiro e sintering uye hunhu hwechimiro uye hunhu hwezvigadzirwa. Zvisinei, tsvakiridzo ye blank forming ishoma. Kunyangwe paine zvidzidzo zvakawanda pamusoro pe reaction mechanism pakati pavo, pane zvidzidzo zvishoma pamusoro pe permeability kinetics, reaction mechanism uye kuumbwa kwechikamu chezvinhu zve alloying process. Pane zvidzidzo zvishoma pamusoro pekugadzirira zvinhu zvine hunhu hunodzorwa uye maumbirwo nekubatanidzwa kwe silicon infiltration nezvimwe zvinhu. Zvinhu izvi zvichiri kuda kudzidzwa.
