Kunze kwechoto che1000 ℃, musystem yekudzivirira zvakatipoteredza yeindasitiri, uye mukati mezvishandiso zvemagetsi zvine hungwaru, pane chinhu chinogara chichitsungirira tembiricha yakanyanyisa - chiripo.zviumbwa zvesimbi zvesilicon carbideinozivikanwa se "goridhe dema remaindasitiri". Sechinhu chakakosha mumunda wemazuva ano weindasitiri, hunhu hwekupisa hunoratidzwa nesilicon carbide ceramics huri kutsanangura patsva kunzwisisa kwevanhu kwezvinhu zvinopisa zvakanyanya.
1, 'Nzira inokurumidza' yekufambisa kupisa
Zvigadzirwa zvesimbi zvesilicon carbide zvine simba rekupisa rakafanana nesimbi, zvine simba rekupisa rakakwira kakawanda kupfuura zvinhu zvesimbi zvakajairika. Simba iri rekupisa rakasiyana rinokonzerwa nemaatomu esilicon carbon akanyatsorongwa muchimiro chayo chekristaro, ayo anoumba nzira dzinoshanda dzekupisa. Kana kupisa kuchiendeswa mukati mechinhu chacho, zvinoita semotokari iri kutyaira mumugwagwa usina kuvharwa, iyo inogona kuparadzira kupisa nekukurumidza uye zvakaenzana, ichidzivirira njodzi dzekuchengetedza dzinokonzerwa nekupisa kwakanyanya munzvimbo iyoyo.
2, Kugara kwenguva refu munzvimbo dzine tembiricha yakakwira
Pakupisa kwakanyanya kwe1350 ℃, zvinhu zvakawanda zvesimbi zvakatonyorova uye zvakakanganisika, nepo silicon carbide ceramics ichiri kugona kuchengetedza chimiro chayo. Kudzivirira kupisa kwakanyanya uku kunobva mukusunga kwakasimba kwe covalent mukati mechinhu, sekuvaka nhare diki isingaparare. Chinonyanya kushamisa ndechekuti munzvimbo dzine kupisa kwakanyanya, dense silica protective layer inoumbwa pamusoro payo, ichigadzira "nhoo yekudzivirira" yechisikigo.
3, 'Mambo weKutsungirira' weHondo yeKutsungirira paTembiricha Yakakwirira
Mumujaho wemarathon wekupisa kwakanyanya, zvinhu zvakawanda zvinosangana nekudzikira kwekushanda nekuda kwekupisa kwenguva refu, nepo reaction sintered silicon carbide ceramics ichiratidza kugara kwenguva refu kunoshamisa. Chakavanzika chiri mukugadzirwa kwemuganhu wezviyo zvakasiyana - dhizaini yetiweki ine mativi matatu yakagadzirwa kuburikidza netekinoroji ye reaction sintering, yakafanana nekubatanidza mamiriyoni e "micro" anchor points kuchinhu chacho. Kunyangwe mushure memaawa zviuru zvekubika pakupisa kwakanyanya, inogona kuramba ichichengetedza kugadzikana kwechimiro che microstructure. Hunhu uhwu hunoita kuti ive sarudzo yakanakisa yekutsiva zvinhu zvesimbi zvechinyakare mumamiriro ezvinhu akadai se continuous casting rollers muindasitiri yesimbi uye zvikamu zvinotakura mutoro zvakanyanya mumidziyo yemakemikari. Inotsanangura zvinorehwa ne "high temperature does not fade" ne "hard strength".
Kana mudziyo wako uchida kuyera miganhu yekupisa, simbi dzesilicon carbide dzinogona kuva 'dzinodzora kupisa' dzinovimbwa nadzo. Semunhu anoshanda muindasitiri iyi, anonyanya kugadzira tekinoroji yekupisa kupisa,Shandong Zhongpenginoshandisa matekinoroji akasiyana-siyana ane patent kuti iwedzere simba remakanika uye mashandiro ekugadzirisa zvinhu uku ichichengetedza hunhu hwakanaka hwekupisa. Kubudirira uku kwetekinoroji hakungoderedzi mari yekugadzira chete, asiwo kunoratidza mikana yakakura yekushandiswa kwesilicon carbide ceramics muminda yeindasitiri iri kubuda.
