Iipropati kunye nokusetyenziswa okuphambili kwe-reaction-sintered silicon carbide

Iipropati ze-silicon carbide ezisintered reaction kunye nokusetyenziswa okuphambili? I-Silicon carbide ikwabizwa ngokuba yi-carborundum okanye isanti engatshiyo, yi-inorganic compound, eyahlulwe yaba yi-silicon carbide eluhlaza kunye ne-black silicon carbide ezimbini. Ngaba uyazi iipropati kunye nokusetyenziswa okuphambili kwe-silicon carbide? Namhlanje, siza kwazisa iipropati kunye nokusetyenziswa okuphambili kwe-silicon carbide.

I-reactive sintering silicon carbide kukusetyenziswa kwesanti ye-quartz, i-calcined petroleum coke (okanye i-coaking yamalahle), i-wood slag (ukuveliswa kwe-green silicon carbide kufuneka kongezwe ityuwa yokutya) kunye nezinye izinto ezikrwada, ngokusebenzisa umbane ofudumezayo oshushu oqhubekayo.

Iimpawu ze-silicon carbide e-reaction-sintered:

1. Ukuqhuba ubushushu kunye ne-coefficient yokwandisa ubushushu ye-silicon carbide. Njengohlobo lwezinto ezichasayo, izitena ezenziwe nge-carbon zinokuxhathisa kakhulu ukutshayiswa. Oku kubonakala kakhulu kwi-coefficient yayo enamandla yokufudumala (i-coefficient yokudlulisa ubushushu) kunye ne-coefficient ephantsi yokwandisa ubushushu.

2, ukuhanjiswa kwe-silicon carbide. I-Silicon carbide yinto ye-semiconductor, ukuhanjiswa kwayo kuyahluka ngohlobo kunye nobungakanani bokungcola okufakwe kwi-crystallization, kwaye ukumelana kuphakathi kwe-10-2-1012Ω·cm. Phakathi kwazo, i-aluminium, i-nitrogen kunye ne-boron zinempembelelo enkulu ekuhanjisweni kwe-silicon carbide, kwaye ukuhanjiswa kwe-silicon carbide ene-aluminium engaphezulu kukhula kakhulu.

3. Ukuxhathisa kwe-silicon carbide. Ukuxhathisa kwe-silicon carbide kuyatshintsha ngokutshintsha kobushushu, kodwa ngaphakathi koluhlu oluthile lobushushu kunye neempawu zobushushu ze-metal resistor ziyaguqulwa. Ubudlelwane phakathi kokuxhathisa kunye nobushushu be-silicon carbide buyinkimbinkimbi ngakumbi. Ukuxhathisa kwe-reaction-sintered silicon carbide kuyanda ngobushushu obunyukayo ukuya kwixabiso elithile, kwaye ukuxhathisa kwehla xa ubushushu bunyuka kwakhona.

Ukusetyenziswa kwe-silicon carbide:

1, izixhobo ezingagugiyo – ezisetyenziswa kakhulu ekwenzeni ivili lesanti, iphepha lokusila, ilitye elijiyileyo, ivili lokusila, intlama yokusila kunye neemveliso ze-photovoltaic kwiiseli ze-photovoltaic, iiseli ze-photovoltaic kunye nezixhobo zokusila, ukusila kunye nokupolisha umphezulu.

2, izinto ezichaseneyo eziphezulu – zingasetyenziswa njenge-deoxidizer yoshishino lwesinyithi kunye nezixhobo ezimelana nokugqwala, ukwenza izinto ezilungiselelwe i-oven yobushushu obuphezulu, iindawo ezizinzileyo, njl.

3, iiseramikhi ezisebenzayo – azinakunciphisa kuphela umthamo we-oven, kodwa zikwaphucula umgangatho weemveliso ze-oven zoshishino, zinciphise ixesha lokujikeleza, zizinto ezifanelekileyo ezingathanga ngqo zokusila i-ceramic glaze, iiseramikhi ezingapheliyo ezingezo-oxide ezinobushushu obuphezulu, ezibonisa i-porcelain ecinyiweyo.

4, iintsimbi ezinqabileyo – amashishini esinyithi nentsimbi, intsimi yokugxila kushishino lwe-metallurgical, anesicelo esithile.

5, enye – isetyenziselwa ukwenza i-far-infrared radiation coating okanye i-silicon carbide plate yomomisi we-far-infrared radiation.

I-silicon carbide ngenxa yeempawu zayo ezigudileyo ze-organic chemical, i-coefficient ephezulu yokudlulisa ubushushu, i-coefficient encinci yokwandisa umgca, i-coefficient elungileyo yokuguguleka, ukongeza kwizinto ezixhathisa ukuguguleka, kukho ezinye iindlela eziphambili zokusetyenziswa, ezinje: ngenkqubo entsha yokwenza i-silicon carbide powder glue kwi-centrifugal impeller okanye kwi-cylinder body cavity, inokuphucula i-criterion yokuguguleka kwaye yonyuse ubomi benkonzo ka-1 ukuya ku-2; Isetyenziselwa ukwenza izinto ezichasene nomgangatho ophezulu, i-coefficient ephezulu yokushisa, i-small size, i-light weight kunye ne-high strength, i-environment and saving effect icacile. I-silicon carbide ekumgangatho ophantsi (equlethe malunga ne-85% SiC) yi-arhente elungileyo ye-deoxidizing, enokusetyenziselwa ukukhawulezisa isantya sokwenza isinyithi, kwaye iluncedo ekulawuleni ukwakheka kunye nokuphucula umgangatho wentsimbi. Ukongeza, i-silicon carbide ikwasetyenziselwa ukwenza izinto ezininzi zokufudumeza zombane i-silicon molybdenum rod.
