Luluphi ukuhlelwa kunye nemathiriyeli yezihluzi ze-ceramic foam?

Izinto ezisisiseko ze-ceramic foam filter zii-silicon carbide, i-zirconium oxide kunye ne-alumina
Isihluzi se-ceramic ye-foam sinefuthe elihle lokuhluza kubhedu okanye kumanzi esinyithi, samkela isakhiwo esine-dimensional-dimensional, ukususa ngokufanelekileyo imixube ene-oxidized kunye neminye imixube engeyiyo isinyithi, i-blocking capture kunye ne-adsorption. Ingaba intsimbi engwevu, intsimbi ye-ductile okanye i-shaft, i-cylinder okanye iindawo ezinkulu eziyinkimbinkimbi, iindawo ezichanekileyo zokuphosa ezihluziweyo, umgangatho wemveliso uya kuba yimiphumo eyanelisayo.
Izihluzi ze-Ceramic foamzikwafanelekile ubhedu, ubhedu, ubhedu kunye nezinye i-alloys zobhedu, ukunciphisa i-turbulence yolwelo lobhedu kunye nokulungiswa kunye nokucoca intsimbi etyhidiweyo. Okuxabiseke kakhulu kukwandiswa okubalulekileyo kobomi benkonzo yobhedu olufunwa kakhulu okanye kubume oburhabaxa obufana nee turbines zeenqanawa zaselwandle, iinxalenye zekhemikhali, njl. njl. Ukwaneziphumo ezihle zokusahlelwa kobhedu ezineemfuno zokugulisa umphezulu. Izihluzi ze-ceramic zogwebu nazo zidlala indima ebalulekileyo ekwenzeni ubhedu lwemveli, ukwenziwa kobhedu lwe-elektroniki kunye neenkqubo eziqhubekayo zokusatywa nokuqengqeleka. Ngenxa yobuninzi bobhedu kunye neealloys, ezibandakanya i-alloys ye-zinc, eyenza ukothuka okukhulu kwe-thermal ngexesha lenkqubo yokuphosa, ukusetyenziswa kwe-silicon carbide foam edibeneyo yokucoca i-ceramic ixhomekeke kwimigaqo engqongqo kubukhulu.
Izinto eziphathekayo
Izinto ezisisiseko kwizihluzi ze-ceramic yi-oxidized clean Zr02.izihluzi ze-zirconiaUbushushu obunganyangekiyo bubushushu obungaphezulu kwe-1760°C, amandla aphezulu kunye nefuthe elihle lobushushu obuphezulu.
Iinxalenye zentsimbi ephosiweyo zisetyenziswa ngokubanzi apho kufuneka amandla aphezulu kunye nobude. Ke ngoko, iinxalenye zentsimbi ephosiweyo zinovakalelo kakhulu kukungcola-okubangelwa ukujikeleza okufutshane, kwaye iimpawu ezibalaseleyo zezihluzo ze-ceramic ezinogwebu zinokususa ngempumelelo ukungcola okukhokelela kumgangatho omfutshane wemveliso. Ukungcola ngokuyininzi kuqulethwe ngamaqhekeza angeyiyo-metallic, i-slag kunye ne-refractory debris, ephucula umgangatho ophezulu kunye neempawu zomatshini zokuphosa kunye nokunciphisa izinga le-scrap.
Isihluzi se-Ceramic foam sinokwenza intsimbi yolwelo igcwalise umngxuma ngokulinganayo ngakumbi, kwaye isinyithi esinyibilikisiweyo sinotyekelo oluphezulu lwesiphithiphithi kwinkqubo yokugalelwa. Isakhiwo sepore esinemigangatho emithathu yeisihluzo se-ceramic foamukuhamba kwesiphithiphithi ekugqibeleni kuguqulelwe kwi-laminar ezinzileyo kakhulu. Ukuhamba kwe-laminar bhetele kuzalisa i-cavity, ngaloo ndlela kuncitshiswe impembelelo ye-corrosion yesisombululo setsimbi kwi-casting cavity kunye nokunciphisa kakhulu izinga lenkunkuma.
