Iiseramikhi ze-alumina, iiseramics ze-silicon carbide kunye neeseramics ze-zirconia

I-alumina ceramic ilula kwizinto eziphathekayo, ikhulile kwitekhnoloji yokuvelisa, iphantsi kweendleko, igqwesileyo ngobulukhuni kunye nokumelana nokunxiba. Isetyenziswa kakhulu kwimibhobho ye-ceramic ekwazi ukumelana nokunxiba, iivalvu ezingagungqiyo njengezinto zombane, kwaye zinokudityaniswa ngezikhonkwane okanye zincanyathiselwe kudonga lwangaphakathi lwezixhobo zokwahlula ezifana ne-industrial vertical mill, i-powder concentrator kunye ne-cyclone, enokubonelela nge-10. amaxesha banxibe ukumelana umphezulu izixhobo. Kwizinto eziphathekayo zokunxiba, isabelo semarike sezinto ze-alumina sinokufikelela malunga ne-60% ~ 70%.

Olona phawu lubalulekileyo lwemathiriyeli ye-ceramic ye-SiC kukuxhathisa ukothuka kwe-thermal. Ngaphantsi kweemeko eziphezulu zokushisa, izinto eziphathekayo zinezixhobo ezizinzileyo zomatshini kwaye zingasetyenziswa ngokuzinzileyo kwi-1800 ℃ ixesha elide. Uphawu lwesibini kukuba izinto ze-silicon carbide zingasetyenziselwa ukwenza iimveliso ezinkulu kunye ne-deformation encinci. Isetyenziswa ikakhulu kwi-preheater ejingayo kwishishini lesamente, i-nozzle ye-ceramic enganyangekiyo kubushushu obuphezulu, umbhobho owela amalahle kunye nombhobho ogqithisa wobushushu obuphezulu weshishini lamandla obushushu. Ngokomzekelo, i-nozzles of burners kwizityalo zamandla ashushu zenziwe nge-silicon carbide, kwaye iimveliso zineempawu zokumelana nokushisa okuphezulu kunye nokuxhatshazwa kokugqoka. Iindlela zokuntywila ze-silicon carbide ceramics ziquka i-reaction sintering kunye ne-pressure sintering. Ixabiso le-reaction sintering liphantsi, iimveliso zirhabaxa ngokwentelekiso, kwaye ingxinano yeemveliso zevacuum sintering ezingenaxinzelelo ziphezulu. Ubunzima beemveliso bufana neemveliso ze-alumina, kodwa ixabiso layo liphezulu kakhulu.

Ukugoba ukugoba kwezinto ze-ceramic zirconia kungcono kunezinto ezinqabileyo. Ixabiso lemarike yangoku ye-zirconia powder iyabiza kakhulu, esetyenziswa kakhulu kwiindawo eziphezulu, ezifana nezixhobo zamazinyo, ithambo lokufakelwa, izixhobo zonyango, njl.
