Iintlobo zeReaction Bonded Silicone Carbide (RBSiC/SiSiC)

Iintlobo zeNkathazoI-Bonded Silicone Carbide (RBSiC/SiSiC)

Okwangoku, kukho inani elikhulu labavelisi ababonelela ngeemveliso zeReaction Bonded SIC kumashishini ahlukeneyo. I-Shandong Zhongpeng Special Ceramics Co., Ltd kufuneka ibe ngomnye wabathengisi ababalaseleyo ngeemveliso ezahlukeneyo zeReaction Bonded SIC, ezifana neNozzle kunye nezinye kwi-Electric power, i-ceramics, i-oven, i-iron kunye ne-steel, i-mine, amalahle, i-alumina, i-petroleum, i-chemical, i-wet desulphurization, imveliso yoomatshini, kunye nezinye iimboni ezikhethekileyo kwihlabathi liphela.

I-Reaction Bonded SIC inokwahlulwahlulwa ibei-silicon carbide ebotshelelwe kwi-reaction-bondkwayei-silicon carbide eyenziwe ngokuphendula, ngokwendlela engenanto yokuqala equlethe ngayo amasuntswana e-silicon carbide.

I-silicon carbide ebotshelelwe kwi-reaction-bond

I-reaction-bonded silicon carbide ibhekisa kwinkqubo yokwenza i-silicon carbide composite. Kwimeko apho i-starting blank ine-silicon carbide powder. Kwinkqubo yokusabela, i-carbon kunye ne-silicon zisabela ukwenza isigaba esitsha se-silicon carbide kwaye zidityaniswe ne-silicon carbide yokuqala. Inkqubo yokulungiselela yile ilandelayo, eyindlela esetyenziswa rhoqo:

Ukuxuba umgubo we-silicon carbide, umgubo we-carbon kunye ne-organic binder;

Ukwenza umxube wome uze uphume kwiibhondi;

Ekugqibeleni, ukufumana i-silicon carbide ebotshelelwe yi-reaction-bonded ngokusebenzisa ukungena kwe-silicon.

I-silicon carbide ebotshelelwe yi-reaction-bonded eyenziwe yile ndlela idla ngokuba neenkozo zekristale ze-silicon carbide eziqinileyo kunye nomxholo ophezulu we-silicon ekhululekileyo. Nangona kunjalo, le ndlela inenkqubo elula kwaye ixabisa kancinci. Okwangoku,

I-silicon carbide eyenziwe yi-reaction

Isithuba sokuqala se-silicon carbide eyenziwe yi-reaction-designed sine-carbide kuphela. Isithuba sokuqala se-carbon eneembobo siphendulwa nge-silicon okanye i-silicon alloy ukulungiselela izinto ezidityanisiweyo ze-silicon carbide. Le nkqubo yaqalwa yiHucke. Indlela yeHucke nayo ineengxaki zayo. Inkqubo yayo yokulungiselela iyinkimbinkimbi ngakumbi. Ixabiso lale ndlela liphezulu. Kwangaxeshanye, inani elikhulu legesi liyavela ngexesha lokuqhekeka kobushushu. Oku kuya kukhokelela ekuqhekekeni okulula kweTshayina. Ke ngoko, le ndlela kunzima ngakumbi ukuvelisa iimveliso ezinkulu.

Ukongeza, i-petroleum coke isetyenziswa njengezinto zokwenza izinto ukulungisa zonke ii-carbon slabs, emva koko kwenziwa i-silicon carbide. Nangona kunjalo, iimpawu zezinto ezilungisiweyo ziphantsi kakhulu. Amandla ayo ngokubanzi angaphantsi kwe-400mpa. Ukufana kwe-silicon carbide efunyenweyo akulunganga. Ngenxa yexabiso eliphantsi le-petroleum coke, ixabiso lale ndlela liphantsi kakhulu.

Xa kuthelekiswa nezinye iindlela zokulungiselela ii-silicon carbide ceramics, indlela yokubopha i-reaction ineenzuzo zayo ezikhethekileyo. Okwangoku, uphando kule ndawo lugxile kakhulu kuphononongo lwenkqubo yokusinta kunye nokuchazwa kwesakhiwo kunye neepropati zeemveliso. Nangona kunjalo, uphando malunga nokwakheka kwezinto ezingenanto luncinci kakhulu. Nangona kukho izifundo ezininzi malunga nendlela yokusabela phakathi kwazo, zimbalwa izifundo malunga ne-permeability kinetics, indlela yokusabela kunye nokwakheka kwesigaba sezinto zenkqubo yokudibanisa. Zimbalwa izifundo malunga nokulungiswa kwezinto ezineempawu ezilawulekayo kunye nezakhiwo ngokudityaniswa kokungena kwe-silicon kunye nezinye izinto. Ezi nkalo zisafuna ukufundwa.
