"Hunhu hwakanaka hunotanga nekutanga; sevhisi ndiyo inonyanya kukosha; kurongeka ikushandira pamwe" ndiyo pfungwa yedu yebhizinesi iyo inogara ichicherechedzwa uye ichiteverwa nekambani yedu nemutengo wakaderera China High Temperature Resistance Molybdenum Graphite Crucible Metal Melting Pot, Seeing anotenda! Tinogamuchira nemwoyo wese mikana mitsva yekumisikidza kudyidzana kwekambani uye tinotarisirawo kusimbisa kudyidzana nevatengi vese vagara varipo kwenguva refu.
Hunhu hwakanaka hunotanga ne: basa ndiro rinotanga; kurongeka ikushandira pamwe” ndiyo pfungwa yedu yebhizinesi iyo inogara ichicherechedzwa uye ichiteverwa nekambani yedu kuti iite basa rayo.Chinopfuta cheChina Molybdenum, Zvikepe zveKupisa Zviri Kutengeswa, Tinopa vatengi vedu basa rine ruzivo, mhinduro nekukurumidza, kutumira nenguva, mhando yepamusoro uye mutengo wakanakisa. Kugutsikana uye chikwereti chakanaka kune mutengi wese ndizvo zvatinokoshesa. Tinotarisa pane zvese zvinodiwa pakugadzirisa maodha evatengi kusvika vagamuchira zvigadzirwa zvakachengeteka uye zvakanaka zvine sevhisi yakanaka yekufambisa zvinhu uye mutengo usingadhuri. Zvichienderana neizvi, zvinhu zvedu zvinotengeswa zvakanaka munyika dziri muAfrica, Mid-East neSoutheast Asia. Tichitevedzera pfungwa yebhizinesi yekuti "mutengi atange, enderera mberi", tinogamuchira vatengi vanobva kumba nekune dzimwe nyika kuti vashande nesu.
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.
