Ndeapi maitiro uye zvinhu zveceramic foam mafirita?

Izvo zvakakosha zveceramic foam sefa ndizvosilicon carbide, zirconium oxide uye alumina
Foam ceramic sefa ine yakanaka kusefa pamvura yemhangura kana simbi, inotora matatu-dimensional chimiro, zvinobudirira kubvisa oxidized musanganiswa uye mamwe asiri-simbi musanganiswa, ichivharira kubatwa uye adsorption. Kunyangwe iri grey iron, ductile iron kana shaft, silinda kana zvikamu zvakakura zvakaoma, zvikamu zvekukanda zvakapepetwa, mhando yechigadzirwa ichave mhedzisiro inogutsa.
Ceramic furo filterszvakare akakodzera mhangura, ndarira, ndarira uye mamwe alloys emhangura, kuderedza mhangura yemvura turbulence uye kugadzirisa uye kuchenesa simbi yakanyungudutswa. Kunyanya kukosha ndeyekuwedzerwa kwakakosha kwehupenyu hwebasa rekukanda mhangura munzvimbo dzinonyanya kudiwa kana dzakaomarara senge turbines dzengarava dzemugungwa, zvikamu zvemakemikari, nezvimwewo. Iyo inewo mhedzisiro yakanaka yekukanda mhangura ine pamusoro pezvinodiwa zvekupenya. Foam ceramic mafirita anoitawo basa rakakosha mukugadzirwa kwemhangura yechinyakare, kugadzirwa kwemhangura yemagetsi uye kuenderera mberi kwekukanda nekukunguruka. Nekuda kwehuwandu hukuru hwemhangura uye alloys, kusanganisira zinc alloys, izvo zvinoburitsa kutyisa kukuru panguva yekukanda, kushandiswa kwesilicon carbide foam yakasanganiswa ceramic mafirita inowanzoiswa pasi pemirairo yakasimba pahukuru.
Material
Iyo yakakosha zvinhu zveceramic mafirita ndeye oxidized yakachena Zr02.zirconia filtersine tembiricha isingadziviriri kupisa yakakwira kupfuura 1760 ° C, kusimba kwepamusoro uye yakanaka-yepamusoro-tembiricha maitiro.
Zvikamu zvesimbi zvakakandwa zvinoshandiswa zvakanyanya uko kusimba kwepamusoro uye kurebesa kunodiwa. Naizvozvo, zvikamu zvesimbi zvakakandwa zvine hanya zvakanyanya nekusachena-induced short-circuiting, uye zvakanakisa hunhu hwefoam ceramic mafirita anogona kunyatsobvisa kusvibiswa kunozotungamira kune chigadzirwa chemhando pfupi-inotenderera. Kusvibiswa kunonyanya kuumbwa ne-non-metallic particles, slag uye refractory marara, iyo inovandudza hutano hwepamusoro uye mechanical properties ye castings uye inoderedza chiyero chezvimedu.
Ceramic foam sefa inogona kuita kuti simbi yemvura izadze gango zvakaenzana, uye simbi yakanyungudutswa ine tsika yakakwira yekuvhiringa mukudurura. Iyo nhatu-dimensional pore chimiro checeramic furo sefamhirizhonga inoyerera inozopedzisira yashandurwa kuita yakanyatsogadzikana laminar kuyerera. Iyo laminar inoyerera zvirinani inozadza mhango, nekudaro ichidzikisa kukanganisa kwekugadzirisa kwesimbi mhinduro pagomba rekukanda uye zvakanyanya kuderedza chiyero chemarara.
