Iindidi ze-Reaction Bonded Silicone Carbide (RBSiC/SiSiC)

Iintlobo zokusabelaiBonded Silicone Carbide (RBSiC/SiSiC)

Okwangoku, kukho inani elikhulu labenzi bokubonelela ngeemveliso zeReaction Bonded SIC kumashishini ahlukeneyo. I-Shandong Zhongpeng Special Ceramics Co., Ltd kufuneka ibe ngomnye wababoneleli abagqwesileyo abaneemveliso ezahlukeneyo ze-Reaction Bonded SIC, ezifana neNozzle kunye nabanye kumandla oMbane, iiseramikhi, i-kiln, intsimbi kunye nentsimbi, umgodi, amalahle, i-alumina, i-petroleum, ikhemikhali. , ukuchithwa kwesulphurization emanzi, ukwenziwa koomatshini, kunye namanye amashishini akhethekileyo ehlabathini.

I-Reaction Bonded SIC inokohlulwa ibei-silicon carbide edibeneyo yokusabelakwayei-silicon carbide eyenziwe ukuphendula, ngokutsho nokuba isiqalo esingenanto siqulethe amasuntswana e-silicon carbide.

I-silicon carbide edibeneyo yokusabela

I-silicon carbide ye-reaction-bond ibhekisa kwinkqubo yokwenza i-silicon carbide composite. Kukwimeko apho ukuqala okungenanto kuqulethe i-silicon carbide powder. Kwinkqubo yokusabela, ikhabhoni kunye nesilicon zisabela ukwenza isigaba esitsha se-silicon carbide kwaye idibanise ne-silicon carbide. Inkqubo yokulungiselela imi ngolu hlobo lulandelayo, oluyindlela eqhelekileyo esetyenziswayo:

Ukuxuba i-silicon carbide powder, i-carbon powder kunye ne-organic binder;

Ukwenza umxube owomileyo kwaye ubotshiwe;

Okokugqibela, ukufumana i-silicon carbide edibeneyo yokuphendula ngokungena kwe-silicon.

I-action-bonded silicon carbide eveliswa yile ndlela ngokubanzi iqulethe i-coarse silicon carbide crystal grains kunye nomxholo ophezulu we-silicon yamahhala. Nangona kunjalo, le ndlela inenkqubo elula kunye neendleko eziphantsi. Ngoku,

I-action-formed silicon carbide

Isiqalo esingenanto se-action-formed silicon carbide iqulethe kuphela i-carbide. Isiqalo esingenanto se-porous carbon siphendulwa nge-silicon okanye i-silicon alloy ukulungiselela imathiriyeli ye-silicon carbide composite. Le nkqubo yaqalwa nguHucke. Indlela yeHucke nayo ineentsilelo zayo. Inkqubo yayo yokulungiselela inzima ngakumbi. Iindleko zale ndlela ziphezulu. Ngexesha elifanayo, inani elikhulu legesi liguquka ngexesha lokuqhekeka kwe-thermal. Oku kuya kukhokelela ekuqhekekeni okulula kweTshayina. Ke ngoko, le ndlela inzima kakhulu ukuvelisa iimveliso ezinobungakanani obukhulu.

Ukongeza, i-petroleum coke isetyenziswa njengento ekrwada ukulungisa zonke ii-carbon slabs, kwaye emva koko i-silicon carbide yenziwa. Nangona kunjalo, iipropati zezinto ezilungiselelwe ziphantsi. Amandla ayo ngokuqhelekileyo angaphantsi kwe-400mpa. Ukufana kwe-silicon carbide efunyenweyo ayilungile. Ngenxa yexabiso eliphantsi lepetroleum coke, ixabiso lale ndlela liphantsi ngokwentelekiso.

Summary

Xa kuthelekiswa nezinye iindlela zamalungiselelo e-silicon carbide ceramics, indlela yokusabela ebotshiweyo ineengenelo zayo ezizodwa. Okwangoku, uphando kule ndawo lugxile kakhulu kwisifundo senkqubo ye-sintering kunye nokubonakaliswa kwesakhiwo kunye neempawu zeemveliso. Nangona kunjalo, uphando malunga nokwakhiwa okungenanto lumbalwa. Nangona kukho izifundo ezininzi kwindlela yokusabela phakathi kwazo, kukho izifundo ezimbalwa malunga ne-permeability kinetics, indlela yokusabela kunye nokwakhiwa kwesigaba semathiriyeli yenkqubo yokuxuba. Kukho izifundo ezimbalwa malunga nokulungiswa kwezinto ezineempawu ezilawulekayo kunye nezakhiwo ngokudibanisa ukungena kwe-silicon kunye nezinye izinto. Le miba kusafuneka ifundwe.
