Chengetedzo yekushandiswa kwesilicon carbide tsvimbo ye kuyedza magetsi emagetsi

1. Paunenge uchishandisa choto chemagetsi, kutonhora kwechoto hakufaniri kudarika chiyero chekushisa kwenguva yakareba kuti udzivise kukanganisa kwechinhu chinopisa. Zvinorambidzwa kudira zvakasiyana-siyana zvinopisa zvinwiwa uye simbi yakanyungudutswa muchoto.

2. Iyo silicon carbide tsvimbo yakaoma uye ine brittle, saka chenjerera paunenge uchitakura nekudzikisa.

3. Iyo silicon carbide tsvimbo dzinofanira kuchengetwa munzvimbo yakaoma kudzivirira kuparara kwealuminium-plated kuguma nekuda kwekunyorova.

4. Yakanyungudutswa KOH, NaOH, Na2CO3 uye K2CO3 inoodza SiC pakupisa kwekupisa. Silicon carbide tsvimbo ichave yakasvibiswa inosangana nealkali, alkaline pasi simbi, sulfates, borides, nezvimwewo, saka haifanirwe kubatwa nesilicon carbide tsvimbo.

5. Wiring yesilicon carbide rod inofanira kunge yakanyatsobatana nechena yealuminium musoro pamucheto unotonhora wetsvimbo kudzivirira kupenya.

6. The silicon carbide rod inopindirana neCl2 pa600 ° C uye inopindirana nemhute yemvura pa1300-1400 ° C. Iyo silicon carbide tsvimbo haina oxidized pazasi 1000 ° C, uye yakanyanya oxidized pa1350 ° C, pa1350-1500 ° C. Firimu inodzivirira yeSiO2 inoumbwa pakati uye inonamatira kumusoro kwesilicon carbide rod kudzivirira SiC kuti irege kuramba ichiwedzera oxidize.

7. Iko kupikisa kukosha kwesilicon carbide rod kunowedzera sezvo nguva yekushandiswa kwesilicon carbide rod inowedzera, uye maitiro anotevera:

SiC + 2O2=SiO2 + CO2

SiC + 4H2O = SiO2 + 4H2 + CO2

Iyo yakakwirira yemukati yeSiO2, iyo yakakura kukosha kwekupokana kwesilicon carbide tsvimbo. Nokudaro, iyo yekare uye itsva silicon molybdenum tsvimbo haigoni kusanganiswa, kana zvisina kudaro kukosha kwekupikisa kuchave kusina kuenzana, izvo zvisingafadzi zvikuru kumunda wekushisa uye hupenyu hwebasa resilicon carbide rods.
