Chinangwa chedu chinofanira kunge chiri chekusimbisa nekuvandudza mhando yepamusoro uye sevhisi yezvinhu zviripo, panguva imwe chete tichigadzira zvigadzirwa zvitsva nemhinduro kuti zvizadzise zvinodiwa nevatengi vedu pamutengo wakanakisisa paChina High Temperature Resisdant Graphite Crucible/Boat Supply, Yeukai kuuya kuzotaura nesu kuti tigadzirise. Uye tinotenda kuti tichagovana ruzivo rwekutengeserana rwunobatsira zvikuru nevatengesi vedu vese.
Chinangwa chedu chinofanira kunge chiri chekusimbisa nekuvandudza mhando yepamusoro uye sevhisi yezvinhu zviripo, ukuwo tichigadzira zvigadzirwa zvitsva nemhinduro kuti zvizadzise zvinodiwa nevatengi vedu.Chitofu cheChina Graphite Foundry, Kiti yeGraphite CrucibleKuti vatengi vave nechivimbo matiri uye vawane sevhisi yakasununguka, tinotungamira kambani yedu nekutendeseka, kutendeseka uye mhando yepamusoro. Tinotenda zvakasimba kuti tinofara kubatsira vatengi kuti vafambise bhizinesi ravo zvinobudirira, uye kuti mazano edu ehunyanzvi nebasa zvinogona kutungamira kusarudzo yakakodzera vatengi.
Zvinhu zvinosanganisa kabhoni/kabhoni(zvino zvichinzi "C / C kana CFC”) imhando yezvinhu zvakasanganiswa zvakagadzirwa nekabhoni uye zvinosimbiswa nekabhoni fiber nezvigadzirwa zvayo (kabhoni fiber preform). Ine simba rekabhoni uye simba rayo guru. Ine hunhu hwakanaka hwemakanika, inodzivirira kupisa, inodzivirira ngura, inodzivirira kukweshana uye hunhu hwekupisa uye magetsi.
CVD-SiCKuputira kune hunhu hwechimiro chakafanana, zvinhu zvidiki, kuramba kupisa kwakanyanya, kuramba oxidation, kuchena kwakanyanya, kuramba acid & alkali uye reagent yeorganic, ine hunhu hwakagadzikana hwemuviri nemakemikari.
Kana tichienzanisa nezvinhu zvegrafiti zvine hutsanana hwakanyanya, girafiti inotanga kuoxidation pa400C, izvo zvinozokonzera kurasikirwa kwehupfu nekuda kweoxidation, zvichikonzera kusvibiswa kwezvakatipoteredza kumidziyo yekunze nemakamuri evacuum, uye kuwedzera kusvibiswa kwenzvimbo ine hutsanana hwakanyanya.
Zvisinei, SiC coating inogona kuchengetedza kugadzikana kwemuviri uye kwemakemikari pa1600 degrees, Inoshandiswa zvakanyanya muindasitiri yemazuva ano, kunyanya muindasitiri yesemiconductor.
Kambani yedu inopa masevhisi ekugadzira SiC coating nenzira yeCVD pamusoro pegraphite, ceramics nezvimwe zvinhu, kuitira kuti magasi akakosha ane kabhoni nesilicon aite pakupisa kwakanyanya kuti awane mamorekuru eSiC akachena, mamorekuru akaiswa pamusoro pezvinhu zvakaputirwa, zvichigadzira SIC protective layer. Iyo SIC yakagadzirwa yakabatana zvakasimba nebase yegraphite, ichipa base yegraphite hunhu hwakakosha, nokudaro zvichiita kuti pamusoro pegraphite pave nekubatana, pasina Porosity, kudzivirira kupisa kwakanyanya, kudzivirira ngura uye kudzivirira oxidation.
Zvinhu zvikuru:
1. Kudzivirira kupisa kwakanyanya kwe oxidation:
Kusakwanisa kuoxidation kuchiri kwakanaka zvikuru kana tembiricha yakakwira kusvika 1600 C.
2. Kuchena kwakanyanya: kunogadzirwa nekuiswa kwemhepo ine makemikari pasi pemamiriro ekupisa kwakanyanya.
3. Kuramba kukurwa kwevhu: kuomarara kwakanyanya, pamusoro pakaoma, zvidimbu zvitete.
4. Kuramba ngura: acid, alkali, munyu uye organic reagents.
