Iiceramics zeAlumina, iiceramics zeSilicon Carbide kunye neeceramics zeZirconia

I-Alumina ceramic ilula kakhulu kwizinto, ivuthiwe kubuchwepheshe bokuvelisa, ixabiso layo liphantsi, ibalasele kakhulu kubunzima bayo kunye nokumelana nokuguguleka. Isetyenziswa kakhulu kwiipayipi ze-ceramic ezingagugulekiyo, iivalvu ezingagugulekiyo njengezinto zokubopha, kwaye inokudityaniswa ngee-studs okanye incamathiselwe eludongeni lwangaphakathi lwezixhobo zokwahlula ezifana ne-industrial vertical mill, i-powder concentrator kunye ne-cyclone, enokubonelela ngokuxhathisa ukuguguleka okuphindwe kalishumi kumphezulu wezixhobo. Kwizinto ezingagugulekiyo, isabelo semarike sezinto ze-alumina sinokufikelela malunga ne-60% ukuya kwi-70%.

Eyona nto ibalulekileyo kwizixhobo ze-ceramic ze-SiC kukumelana kakuhle nokutsha kobushushu. Phantsi kweemeko zobushushu obuphezulu, ezi zinto zineempawu ezizinzileyo zoomatshini kwaye zingasetyenziswa ngokuzinzileyo kwi-1800 ℃ ixesha elide. Uphawu lwesibini kukuba izinto ze-silicon carbide zingasetyenziselwa ukwenza iimveliso ezinkulu ezine-deformation encinci. Zisetyenziswa kakhulu kwishishini lesamente elixhonywayo ngaphambi kweheater, i-nozzle ye-ceramic engagugiyo kubushushu obuphezulu, ipayipi yokuwa kwamalahle kunye nepayipi yokuhambisa ubushushu obuphezulu kwishishini lamandla obushushu. Umzekelo, ii-nozzles zezitshisi kwizityalo zamandla obushushu zenziwe nge-silicon carbide, kwaye iimveliso zineempawu zokuxhathisa kubushushu obuphezulu kunye nokuxhathisa ukuguguleka. Iindlela zokutshiza ze-silicon carbide ceramics ziquka ukutshiza kwe-reaction kunye nokutshiza kwe-pressureless. Ixabiso lokutshiza kwe-reaction liphantsi, iimveliso zirhabaxa, kwaye uxinano lweemveliso zokutshiza ze-vacuum ezingenaxinzelelo luphezulu. Ubulukhuni beemveliso bufana nobo beemveliso ze-alumina, kodwa ixabiso lazo liphezulu kakhulu.

Ukumelana nokugoba kwezinto zeseramikhi ze-zirconia kungcono kunoko kwezinto ezibuthathaka. Ixabiso langoku lemarike le-zirconia powder libiza kakhulu, elisetyenziswa kakhulu kwiindawo eziphezulu, ezifana nezixhobo zamazinyo, amathambo okwenziwa, izixhobo zonyango, njl.
