Munzvimbo dzakawanda dzinoshandiswa mumaindasitiri dzinopisa zvakanyanya, zvitofu zvinobatika zvine basa guru semidziyo inokosha yekubata nekudziya zvinhu.Zvigadziko zvesimbi zvesimbi zvesilicon carbide, nekushanda kwavo kwakanaka, zvishoma nezvishoma vari kuva sarudzo inodiwa mumaindasitiri akasiyana-siyana.
1. Chii chinonzi silicon carbide ceramic crucible
Chinopisirwa chesimbi chesilicon carbide ceramic crucible chigadziko chakaita sendiro chakadzika chakagadzirwa zvakanyanya nesilicon carbide ceramic material. Silicon carbide isanganiswa ine ma bond akasimba e covalent, uye makemikari ayo akasiyana anoisa ma crucibles ane hunhu hwakawanda hwakanaka. Zvichienzaniswa nemidziyo yegirazi yakajairika, ma crucibles esilicon carbide ceramic anogona kutsungirira tembiricha yakakwira uye zvishandiso zvakanaka zvekupisa kupisa zvakanyanya.
2, Mabhenefiti eSilicon Carbide Ceramic Crucibles
1. Kudzivirira kupisa kwakanyanya: Zvigadziko zvesimbi zvesilicon carbide zvinogona kutsungirira kupisa kusvika pa1350 ℃. Simba rezvinhu zvesimbi zvakajairika richadzikira zvakanyanya pa1200 ℃, nepo simba rekukotama resilicon carbide richiri kuramba riri pa1350 ℃. Hunhu uhwu hunoita kuti ishande zvakanaka mukunyunguduka, kupisa uye mamwe maitiro, zvichipa nzvimbo yakagadzikana yekupisa kwepamusoro yezvinhu uye kuve nechokwadi chekufambira mberi kwakanaka kwemaitiro acho.
2. Kudzivirira kuoxidation kwakanaka: Zvigadziko zvesimbi zvesilicon carbide zvinogona kuchengetedza kudzivirira kuoxidation kwakanaka munzvimbo dzinopisa zvakanyanya. Nekuwedzera kwehuwandu hwesilicon carbide, kudzivirira kuoxidation kwechinhu chinopisirwa kunowedzera kuvandudzwa. Izvi zvinoreva kuti hachioxidized nyore nyore uye hachina kukuvara panguva yekushandiswa kwenguva refu pakupisa kwakanyanya, zvichiwedzera hupenyu hwacho hwebasa, zvichideredza kuwanda kwekutsiva chinhu chinopisirwa, uye zvinoderedza mari yekugadzira.
3. Kugadzikana kwakanaka kwemakemikari: Zvigadzirwa zvesilicon carbide zvinodzivirira zvakanyanya kupwanywa nezvinoparadza. Mumaindasitiri anosanganisira zvinhu zvakasiyana-siyana zvemakemikari zvakaita sesimbi uye makemikari, hazvipindi nemakemikari azvinosangana nawo, nokudaro zvichiita kuti zvinhu zvakanyungudutswa kana kuti zvinopindirana zvive zvakachena, zvichidzivirira kusvibiswa, uye kuvandudza kunaka kwechigadzirwa.
4. Kuomarara kwakanyanya uye kuramba kupfeka: Silicon carbide ine kuomarara kwakanyanya, izvo zvinoita kuti crucible inogadzirwa ive yakasimba uye inogona kuramba kupfeka kana tembiricha yakakwira. Painoshandiswa kwenguva refu, inogona kuchengetedza chimiro chayo uye haipfeki kana kukanganisika zviri nyore, zvichiwedzera kuve nechokwadi chekuti inoshanda uye inogara kwenguva refu.
3, minda yekushandiswa kwesilicon carbide ceramic crucibles
1. Indasitiri yesimbi: Ingave iri kunatswa kwesimbi dzesimbi dzakadai sesimbi, kana kunyunguduka kwesimbi dzisina simbi uye alloys dzadzo dzakadai semhangura, aruminiyamu, zinc, nezvimwewo, silicon carbide ceramic crucibles ine basa rakakosha. Inogona kutsungirira kuputsika kwesimbi inopisa zvakanyanya, ichivimbisa kufambira mberi kwakanaka kwekunyunguduka kwesimbi, ukuwo ichivimbisa kuchena kwesimbi uye kuvandudza mhando yezvigadzirwa zvesimbi.
2. Indasitiri yemakemikari: inoshandiswa pakuita makemikari anodziya zvakanyanya uye kugadzirisa ngura. Nekuda kwekugadzikana kwayo kwakanaka kwemakemikari uye kuramba kwayo kupisa kwakanyanya, inogona kushanda zvakanaka pasinei nezvinhu zvakasiyana-siyana zvemakemikari nenzvimbo dzinodziya zvakanyanya, ichivimbisa kufambira mberi kwakanaka kwemakemikari uku ichidzivirira crucible pachayo kuti isaora kana kukuvara.
3. Kirau yemumaindasitiri: inoshandiswa semudziyo wekupisa wekupisa zvinhu zvakasiyana-siyana zvemumaindasitiri, zvakaita sezvidhinha zvisingatsvi. Nekushandisa mafambiro ayo akanaka ekupisa uye kudzivirira kupisa kwakanyanya, inogona kukurumidza uye zvakaenzana kutamisa kupisa, kuve nechokwadi chekuti zvinhu zvinopisa zvakanaka, uye kuvandudza mashandiro esimba.
Zvigadziko zvesimbi zvesilicon carbide, zvine zvakanakira zvakawanda zvakaita sekudzivirira kupisa kwakanyanya, kudzivirira oxidation, kudzivirira kupera, uye kugadzikana kwemakemikari, zvakaratidza kukosha kukuru muindasitiri dzakawanda uye zviri mumidziyo yakakodzera mumunda weindasitiri unopisa kupisa zvakanyanya. Nekufambira mberi kuri kuramba kuchiita tekinoroji uye kuvandudzwa, tinotenda kuti zvigadziko zvesimbi zvesilicon carbide zvichashandiswa muminda yakawanda uye zvichapa rutsigiro rwakasimba mukusimudzira maindasitiri akasiyana-siyana.
