Kambani yedu inosimbisa kuti "hunhu hwechigadzirwa ndiwo hwaro hwekupona kwekambani; mufaro wemutengi ndiwo uchava mugumo wekambani; kuvandudzwa kunogara kuripo ndiko kutsvaga vashandi nekusingaperi" pamwe nechinangwa chekuti "mukurumbira wekutanga, mutengi kutanga" weFekitori inopa zvakananga China Electro Graphite Block, Vashandi vedu vachishandisa matekinoroji epamusoro vanopa mhinduro dzakanaka kwazvo dzinofarirwa uye dzinofarirwa nevatengi vedu pasi rese.
Kambani yedu inosimbisa kuti "hunhu hwechigadzirwa ndiwo musimboti wekurarama kwekambani; mufaro wemutengi ndiwo uchava mugumo wekambani; kuvandudzwa kunogara kuripo ndiko kutsvaga vashandi nekusingaperi" pamwe nechinangwa chekuti "mukurumbira kutanga, mutengi kutanga"Chivharo cheKabhoni, China Graphite Block, Vashandi vedu vari kutevedzera pfungwa ye "Kubudirira kwakavakirwa pakuvimbika uye kudyidzana", uye pfungwa ye "Hutano hwepamusoro-soro neBasa Rakanaka". Zvichienderana nezvinodiwa nemutengi wese, tinopa masevhisi akagadzirirwa vatengi kuti vabudirire pazvinangwa zvavo. Tinokugamuchirai vatengi vanobva kumusha nekune dzimwe nyika kuti vafone uye vabvunze!
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.
