Serudzi rutsva rwezvinhu zvisiri zvesimbi, mhepo yemuchadenga sintered silicon carbide ceramic zvigadzirwa zvakashandiswa zvakanyanya muchoto, desulfurization uye kuchengetedzwa kwezvakatipoteredza, indasitiri yemakemikari, simbi, aerospace uye mamwe minda. Nekudaro, kushandiswa kwemuchadenga kudzvanywa sintered silicon carbide ceramic zvigadzirwa zvichiri muchikamu chakajairwa, uye kune huwandu hukuru hweminda yekushandisa iyo isati yave yakakura-kukura, uye saizi yemusika yakakura. Semugadziri weatmospheric pressure sintered silicon carbide ceramics, tinofanira kuenderera mberi nekusimbisa kukura kwemusika, zvine musoro kuvandudza kugona kwekugadzira, uye kuva pachinzvimbo chepamusoro mundima itsva yekushandisa yesilicon carbide ceramics.
Kumusoro kweindastiri kunonyanya kumanikidzwa kwemhepo sintered silicon carbide kunyungudutsa uye kugadzirwa kwehupfu hwakatsetseka. Chikamu chepasi cheindastiri chinovhara huwandu hwakasiyana, kusanganisira angangoita ese maindasitiri anoda kupisa kwakanyanya, kupfeka uye corrosion inodzivirira zvinhu.
(1) Indasitiri yepamusoro
Silicon carbide poda uye simbi silicon poda ndiyo huru mbishi zvinhu zvinodiwa neindasitiri. Kugadzirwa kwesilicon carbide kweChina kwakatanga muma1970. Mushure memakore anopfuura makumi mana ebudiriro, indasitiri yasvika kure. Smelting tekinoroji, zvigadzirwa zvekugadzira uye zviratidzo zvekushandisa simba zvasvika padanho rakanaka. Inosvika makumi mapfumbamwe muzana epasi rose silicon carbide inogadzirwa muChina. Mumakore achangopfuura, mutengo wesilicon carbide powder hauna kuchinja zvakanyanya; Metal silicon poda inogadzirwa zvakanyanya muYunnan, Guizhou, Sichuan nedzimwe nzvimbo dzekumaodzanyemba kwakadziva kumadokero. Kana mvura nemagetsi zvawanda muzhizha, mutengo wesimbi silicon poda wakachipa, nepo munguva yechando, mutengo wacho unokwira zvishoma uye unoshanduka, asi kazhinji wakagadzikana. Iko kuchinjwa kwemitengo yezvinhu zvakabikwa muindasitiri yekumusoro kune imwe mhedzisiro pamitemo yemitengo yechigadzirwa uye nhanho dzemitengo yemabhizinesi muindasitiri.
(2) indasitiri yepasi
Iyo yakadzika yeindastiri ndiyo silicon carbide ceramic chigadzirwa application indasitiri. Silicon carbide ceramic zvigadzirwa kwete chete zvakasiyana, asiwo kuita kwakanakisa. Inoshandiswa zvakanyanya mukuvaka, sanitary ceramics, zuva nezuva ceramics, magineti zvinhu, girazi-ceramics, mavira indasitiri, mota, pombi, boilers, zviteshi zvemagetsi, kuchengetedza kwezvakatipoteredza, kugadzira mapepa, peturu, simbi, indasitiri yemakemikari, muchina, aerospace uye mamwe minda. Nekuita kwepamusoro kwesilicon carbide ceramic zvigadzirwa zvave kuzivikanwa neakawanda maindasitiri, mashandisirwo emhando yesilicon carbide ceramic zvigadzirwa zvichawedzera uye zvakafara. Hutano, hwakasimba uye nekukasira kusimudzira kweindasitiri yepasi kunopa nzvimbo yakakura yemusika yeindasitiri uye kukurudzira kurongeka kweindasitiri yese.
Nekushandiswa kwakakura kwemuchadenga kudzvanywa sintered silicon carbide ceramic zvigadzirwa, kudiwa kwemusika kuri kuwedzera zvakare, kukwezva chikamu chikuru cheguta mumunda wesilicon carbide ceramic kugadzira. Kune rimwe divi, chiyero cheiyo silicon carbide indasitiri inoramba ichikura, uye yekutanga dunhu kugadzirwa inoparadzirwa zvishoma nezvishoma kunzvimbo dzese dzenyika. Munguva pfupi yemakore gumi, iyo silicon carbide indasitiri yakagadzira nekukurumidza. Nekune rumwe rutivi, nepo ukuru hweindasitiri ichiramba ichiwedzera, iri kutarisanawo nechiitiko chemakwikwi akashata. Nekuda kweiyo yakaderera yekupinda chikumbaridzo cheindasitiri, nhamba yemabhizinesi ekugadzira yakakura, saizi yemabhizinesi akasiyana, uye mhando yechigadzirwa haina kuenzana.
Mamwe mabhizinesi makuru anotarisa pakuvandudza tekinoroji uye mutsva wechigadzirwa kutsvaga nekusimudzira; Chikero chinoramba chichiwedzera, uye kuoneka uye pesvedzero yekambani iri kuwedzera zuva nezuva. Panguva imwecheteyo, vagadziri vadiki vanowedzera vanogona kungovimba nemutengo wakaderera wekutora maodha, zvichitungamira kumakwikwi akashata muindasitiri. Makwikwi ari muindasitiri anotyisa, uye indasitiri icharatidzawo maitiro epolarization.
