Ihlala isikhathi eside, ingangeni manzi futhi ingagugi, izinto ezintsha ze-silica graphite

Incazelo emfushane:

I-Ningbo VET Energy Technology Co., Ltd. iyibhizinisi lobuchwepheshe obuphezulu elisungulwe eShayina. Singumkhiqizi ochwepheshe kanye nomhlinzeki wemikhiqizo ye-Graphite silicide.

Amathegi Omkhiqizo

I-graphite ene-siliconized iyinto ehlanganisiwe lapho i-silicon carbide inamathele khona ebusweni be-substrate ye-graphite. Inezici zobulukhuni obuphezulu, amandla aphezulu okusebenza kanye nokumelana nokuguguleka kwe-silicon carbide, kanye nezakhiwo zokuzigcoba kanye nokumelana nokushaqeka kokushisa kwe-graphite. Iyinto efanelekile yokungqubuzana kanye nezinto zokuvala zomshini, ezifanele ukuvalwa ngomshini kwamaphampu amanzi ahlukahlukene, amaphampu kawoyela, amaphampu amakhemikhali, kanye nama-bearings amaphampu amakhulu ahlukahlukene anesivinini esikhulu kanye nomthwalo omkhulu. Ngaphezu kwalokho, i-graphite ene-siliconized inokumelana okuhle kwe-oxidation, ukumelana nokushaqeka kokushisa, i-porosity ephansi, kanye nokuqhuba okuthile kukagesi, futhi ingasetshenziswa njengezinto ezifana neziqhumane zokuncibilikisa insimbi kanye namapayipi okudonsa.

Ukwakheka kwe-siliconizedI-graphite iyafana, ubuso buhambisana nengaphakathi, futhi isilinganiso sokwakheka kwe-silicon carbide ne-graphite singalungiseka. Uma okuqukethwe kwe-silicon carbide kuphakeme, kulapho ubukhulu bezinto zokwakha bukhula khona, kulapho amandla okucindezela aphezulu, futhi ukumelana kuyanda.
