Mumakore achangopfuura, kudiwa kwezvinhu zvisingakuvadzi nharaunda uye zvinoshanda zvakanaka kwave kuri kuwedzera mumaindasitiri akasiyana-siyana. Chimwe chezvinhu zvitsva zvakadaro chakabata pfungwa dzevaongorori nemainjiniya iceramics yemuchi. Izvi zvinhu zvine chimiro chakasiyana chemuchi, zvichipa mabhenefiti akawanda uye hunyanzvi mukushandiswa kwazvo. Chinyorwa chinotevera chinopa ongororo yakadzama yeceramics yemuchi, ichikurukura mhando dzayo, hunhu hwayo, kuumbwa kwemakemikari, maitiro ekugadzirira, uye mashandisirwo akawanda mumaindasitiri akadai semotokari, makemikari, simba remagetsi, nezvimwewo. Nekunzwisisa kugona kweceramics yemuchi, tinogona kushandisa zvirinani mabhenefiti ayo uye kugadzira nzira yeramangwana rakagadzikana uye rinoshanda muzvikamu zvakasiyana.
1、Chii chinonzi huchi Cerambs
Zvigadzirwa zvehoneycomb chigadzirwa chitsva checeramic chine chimiro chakafanana nechimiro chehuchi. Pakutanga chaishandiswa mukuchenesa utsi hwemotokari diki, uye ikozvino chinoshandiswa zvakanyanya mumaindasitiri akadai semakemikari, simba remagetsi, simbi, peturu, zvemagetsi, uye michina, nekushandiswa kwakakura uye mikana yakanaka. Zvigadzirwa zvehoneycomb zvinogona kugadzirwa nezvinhu zvakasiyana-siyana, kunyanya zvinosanganisira cordierite, mullite, alumina titanate, activated carbon, silicon carbide, activated alumina, zirconia, silicon nitride, uye composite matrices.
2、Mhando dzeCeramics dzeUchi
Zviumbwa zveuchi zvinogona kukamurwa kuita zvikamu zvina zvikuru zvichienderana nemashandisirwo azvo: nzvimbo dzinochengeterwa kupisa, zvinhu zvekurongedza, zvinhu zvinotakura zvinhu zvinokonzeresa kupisa, uye zvinhu zvekusefa.
Matumbu ekuchengetedza kupisa eceramic ehuchi ane simba rekupisa rinodarika 1000 kJ/kg, nekupisa kwakanyanya kushanda kuri 1700℃. Anogona kuchengetedza mafuta anopfuura 40% mumaovheni akadai semaovheni ekupisa, maovheni ekubikira, maovheni ehomogenizing, uye maovheni anotsemuka, anowedzera kugadzirwa neinopfuura 15%, uye anoderedza tembiricha yeutsi hunobuda kusvika pasi pe150℃.
Zvinhu zvekurongedza zveceramic zvehuchi zvine nzvimbo yakakura uye simba riri nani pane zvimwe zvinhu zvekurongedza zvakaita sehuni, zvichiita kuti gasi ripararire zvakaenzana, kusapindirana kwemubhedha, kushanda kuri nani, uye hupenyu hwebasa hurefu. Zvinoshandiswa sezvinhu zvekurongedza muindasitiri yepetrochemical, pharmaceutical, uye fine chemicals uye zvakabudirira zvikuru.
Zviumbwa zvemaseramiki zveuchi zvinobatsira zvikuru kana zvichishandiswa sezvinhu zvinosimudzira kushanduka kwezvinhu. Zvichishandisa zvinhu zvemaseramiki zveuchi sezvinhu zvinotakura zvinhu uye zvichishandisa zvinhu zvakasiyana zvekufukidza, zvinogadzirwa nesimbi dzinokosha, simbi dzisingawanzoonekwi, uye simbi dzinoshanduka, zvichiita kuti pave nekushanda kwakasimba kwekugadzira zvinhu, kugadzikana kwekupisa kwakanyanya, kugara kwenguva refu, uye simba rakawanda.
3、Hunhu hweMaseramiki eUchi
Simba guru, kuramba kupisa kwakanyanya, kuramba ngura, uye kuramba kupfeka zvinoita kuti zviumbwa zvemuzinga zvikodzere nzvimbo dzakasiyana siyana dzekuchengetedza nharaunda. Zvimwe zvinhu zvinosanganisira:
Nzvimbo yakakwirira
Kureba kwakanyanya uye dhayamita yepore yakafanana
Kuderera kwekumanikidzwa kwakaderera
Kuwanda kwekuwedzera kwekupisa kwakaderera
Kupisa kwakanyanya uye kuramba kurira
Kuramba kwakanyanya kukanganiswa nengura yemakemikari (anti-acid ≥99.8%)
Simba guru rekumanikidza
4、Kuumbwa kweMakemikoro eUchi
Zvigadziko zveuchi zveceramic zvinowanzogadzirwa nekaolin, talc, upfu hwearuminiyamu, uye ivhu. Mazuva ano, nekuwedzera zeolite nezvimwe zvinhu zvinoramba, zvimwe zvinhu zvinogona kuwanikwa zvezvinhu izvi.
Zvinhu zvekuvaka (MOC):
Cordierite
Kuumbwa kwemakemikari eCordierite:
Alumina: 35.2±1.5%
Silika: 50.9±1.5%
Magnesia: 13.9±1.5%
5、Maitiro Ekugadzirira Uchi hweCeramics
Zviumbwa zvehuchi zvinogona kugadzirwa nezvinhu zvakasiyana-siyana. Zvinhu zvikuru zvinosanganisira cordierite, mullite, aluminium titanate, activated carbon, silicon carbide, activated alumina, zirconia, silicon nitride, uye composite substrates dze cordierite-mullite ne cordierite-aluminum titanate.
Mushure mekuumba hupfu hwekabhoni kana granules dzakagadziriswa kuita chimiro checeramic yemuchi, kugona kwekuchenesa uye kurapa mvura yakasviba kunovandudzwa zvakanyanya, kunyanya muindasitiri yemishonga yekubvisa tsvina, kushaya mvura mumuviri, uye kubvisa ruvara rwemishonga inorwisa mabhakitiriya, mahormone, mavhitamini, majekiseni e nucleic acid, uye mamwe majekiseni akasiyana-siyana nemishonga. Sezvo zviumbwa zve ceramic zvemuchi zvichigadzirwa kuburikidza ne extrusion, zvimwe zvinowedzerwa zvakasiyana-siyana zvinofanirwa kuwedzerwa kune zvinhu zvikuru kuti muviri wevhu uwedzere kupfava uye kuyerera. Izvi zvinowedzerwa zvinosanganisira zvinonyanya kusunga, plasticizers, deflocculants, lubricants, uye wetting agents. Uyezve, kunewo zvinhu zvinochengetedza mvura, zvinhu zvinochera, zvinhu zvinodzivirira static, zvinhu zvinodzivirira colloidal, uye zvinhu zvinogadzirisa. Parizvino, starch, carboxymethyl cellulose, uye polyvinyl alcohol zvinoshandiswa zvakanyanya sezvinobatanidza, tung oil uye stearic acid sezvizoro, uye glycerin sepurasitiki.
6、Mashandisirwo eUchi Cerambs
Zvitakuri zveCatalyst
Kana zvichishandiswa senzira dzekutakura zvinhu, zvigadziko zvemuchi (honeycomb ceramics) zvinonyanya kushandiswa mukuchenesa utsi hwemotokari, kubvisa hwema hwegasi rinobuda muboiler (NOx), kubvisa hwema hwema hunobuda muindasitiri, uye kubvisa magasi ane chepfu uye anokuvadza. Zvigadziko zvemuchi (honeycomb ceramic catalyst catalysts) zvinoshandiswa mukuchenesa utsi hwemotokari zvinonyanya kushandiswa sezvigadziko zvemuchi (cordierite honeycomb ceramics) zvakaputirwa neγ-Al2O3.
Fenicha yeKirni inopikisa
Midziyo yemidziyo yeceramic yemuchini yemuchini yakabviswa ine huremu hwakareruka ne60%-75% pane midziyo yemidziyo yemuchini yechinyakare, zvichibvumira kutamiswa kwekupisa nekukurumidza uye kupiswa nekukurumidza. Kushandisa ceramic yemuchini sechitsigiro chekupfura maferrite kana zvimwe zvigadzirwa zvemagetsi kunobatsira kuvandudza mashandiro ezvigadzirwa.
Mafirita ekufambisa madziro
Zviumbwa zvemuzinga zvine madziro matete, zvine maburi zvinogona kushandiswa kusefa nekuchenesa zvidimbu zvekabhoni mumagasi eutsi hweinjini yedhiziri (pamhepo inosvika 500℃).
7、Mukupedzisa, zvigadziko zvemuzinga zvinhu zvinoshanduka-shanduka uye zvitsva zvine chimiro chemuzinga chakasiyana chinopa mabhenefiti akasiyana-siyana. Zvinoshandiswa mumaindasitiri akasiyana-siyana, anosanganisira mota, makemikari, simba remagetsi, simbi, peturu, zvemagetsi, uye michina. Hunhu hwazvo hwakanaka, hwakadai sekusimba kwakanyanya, kuramba kupisa kwakanyanya, kuramba ngura, uye kuramba kupfeka, zvinoita kuti zvikodzere kushandiswa kwakasiyana-siyana, kusanganisira nzvimbo dzekuchengetera kupisa, zvinhu zvekurongedza, zvinhu zvinotakura zvinhu, uye zvinhu zvekusefa. Nekufambira mberi kuri kuramba kuchiita sainzi yezvinhu uye kudiwa kuri kukura kwezvinhu zvine hushamwari uye zvinoshanda zvakatipoteredza, zvigadziko zvemuzinga zvingangoita basa rakakosha mumaindasitiri akasiyana-siyana, zvichivimbisa ramangwana rakajeka mukuvandudzwa kwazvo uye mashandisirwo azvo.
