Uphuhliso lweshishini loxinzelelo lwe-atmospheric sintered silicon carbide

Njengohlobo olutsha lwezinto ezingezona zentsimbi, uxinzelelo lwe-atmospheric sintered silicone carbide iimveliso zeceramic zisetyenziswe ngokubanzi kwi-kiln, i-desulfurization kunye nokukhuselwa kwendalo, ishishini lemichiza, intsimbi, i-aerospace kunye nezinye iindawo. Nangona kunjalo, ukusetyenziswa koxinzelelo lwe-atmospheric sintered silicon carbide ceramic iimveliso zisekwinqanaba eliqhelekileyo, kwaye kukho inani elikhulu lemimandla yesicelo engakhange ibe nophuhliso olukhulu, kwaye ubungakanani bentengiso bukhulu. Njengomvelisi we-atmospheric pressure sintered silicone carbide ceramics, kufuneka siqhubeke nokomeleza uphuhliso lwemarike, ngokufanelekileyo siphucule umthamo wemveliso, kwaye sibe kwindawo ephezulu kwintsimi yesicelo se-silicon carbide ceramics.

Umgangatho ophezulu weshishini ubukhulu becala kuxinzelelo lwe-atmospheric sintered silicon carbide smelting kunye nokuveliswa komgubo ocolekileyo. Inxalenye esezantsi yoshishino ibandakanya uluhlu olubanzi, kubandakanywa phantse onke amashishini afuna ubushushu obuphezulu, ukunxiba kunye nezixhobo ezixhathisa ukubola.

(1) Ushishino oluphezulu

I-silicon carbide powder kunye ne-metal silicon powder zezona zinto zifunwayo lishishini. Imveliso yesilicon carbide yaseTshayina yaqala ngeminyaka yoo-1970. Emva kweminyaka engaphezu kwama-40 yophuhliso, ishishini liye lahamba indlela ende. Itekhnoloji yokunyibilikisa, izixhobo zokuvelisa kunye nezalathi zokusetyenziswa kwamandla zifikelele kumgangatho olungileyo. Phantse i-90% ye-silicon carbide yehlabathi iveliswa e-China. Kwiminyaka yakutshanje, ixabiso le-silicon carbide powder alitshintshanga kakhulu; I-Metal silicon powder iveliswa ikakhulu eYunnan, eGuizhou, eSichuan nakweminye imimandla ekumzantsi-ntshona. Xa amanzi kunye nombane zininzi ehlotyeni, ixabiso le-silicon powder lincinci, ngelixa ebusika, ixabiso liphezulu kwaye liyaguquguquka, kodwa lizinzile ngokubanzi. Utshintsho lwamaxabiso ezinto eziluhlaza kushishino oluphezulu lunempembelelo ethile kwimigaqo-nkqubo yexabiso lemveliso kunye namanqanaba eendleko zamashishini kushishino.

(2) ishishini elisezantsi

Umzantsi weshishini lishishini le-silicon carbide ceramic application yemveliso. Iimveliso ze-silicon carbide ceramic azifani nje kuphela, kodwa kunye nokusebenza okugqwesileyo. Isetyenziswa ngokubanzi kulwakhiwo, iiseramikhi zococeko, iiseramikhi zemihla ngemihla, izixhobo zemagneti, iiglasi-zeramics, iziko zoshishino, iimoto, iimpompo, iibhoyila, izikhululo zamandla, ukukhuselwa kwendalo, ukwenza iphepha, i-petroleum, isinyithi, imboni yeekhemikhali, oomatshini, i-aerospace kunye nezinye iinkalo. Ngokusebenza okuphezulu kweemveliso ze-silicon carbide ceramic kuye kwaqatshelwa ngamashishini amaninzi nangaphezulu, uluhlu lwezicelo zeemveliso ze-silicon carbide ceramic ziya kuba zibanzi nangakumbi. Uphuhliso olusempilweni, oluzinzileyo nolukhawulezayo loshishino olusezantsi luya kubonelela ngesithuba semarike esibanzi kushishino nokukhuthaza uphuhliso olucwangcisiweyo loshishino luphela.

Ngokusetyenziswa okubanzi koxinzelelo lwe-atmospheric sintered silicon carbide ceramic products, imfuno yentengiso nayo iyanda, itsalelela inxalenye enkulu yemali kwicandelo le-silicon carbide ceramic production. Kwelinye icala, isikali somzi mveliso we-silicon carbide siyaqhubeka nokukhula, kwaye imveliso yengingqi yokuqala isasazeka kancinci kuzo zonke iindawo zelizwe. Ngexesha elifutshane leminyaka elishumi, ishishini le-silicon carbide liphuhliswe ngokukhawuleza. Kwelinye icala, ngelixa isikali soshishino siqhubeka sisanda, sikwajongene nemeko yokhuphiswano olubi. Ngenxa yomgangatho ophantsi wokungena kwishishini, inani lamashishini emveliso likhulu, ubukhulu bamashishini buhlukile, kwaye umgangatho wemveliso awulingani.

Amanye amashishini amakhulu agxile ekuphuculeni iteknoloji kunye nophando lwemveliso entsha kunye nophuhliso; Isikali siyaqhubeka sisanda, kwaye ukubonakala kunye nempembelelo yenkampani iyanda imihla ngemihla. Ngelo xesha, abavelisi abancinci abancinci banokuthembela kuphela kwisicwangciso sexabiso eliphantsi lokubamba imiyalelo, ekhokelela kukhuphiswano olubi kwishishini. Ukhuphiswano kwishishini lubukhali, kwaye ishishini liya kubonisa umkhwa wepolarization.
