Silicon Carbide Brick siam chhuahna bulpui ber
Silicon carbide brick siamna atana "signature formula" hian cake siam ang chiah hian chiang taka siam a mamawh a ni:
- Silicon carbide chi hrang hrang: 60%–90% vel a awm a; thianghlimna level hian thermal conductivity leh corrosion resistance a hril.
- Binder system: Leilung, silica sol emaw, resin emaw thlan theih; molding chakna leh sintering activity a tichiang.
- Trace additives: Silicon metal powder hian oxidation resistance a tichak a, rare-earth oxides erawh chuan high{1}}temperature stability a ti tha thung.
Processing-a "Magic Moments" awmte chu
Raw material-in temperature sang tak a tawn hian thilmak a thleng thin:
- Molding stage: 200–300 MPa-a compression hmanga siam; density deviation chu 0.5% hnuaiah a awm reng tur a ni.
- Drying phase: 80 degree-ah darkar 48 chhung zawi zawiin a vawt a; moisture content chu 0.3% hnuai lam control tur a ni.
- Sintering key: Nitrogen boruak hnuaia darkar 18 chhung 1450 degree-a kah chuan silicon carbide grain boundary te chu a fusion tha hle.
Formula hman dan chi hrang hrang
Silicon carbide brick hmanna hrang hranga hman tur chu tailored suit ang mai a ni:
- Metallurgical bricks: >85% silicon carbide a awm a, silicon metal coating a awm bawk; slag erosion laka invenna chak tak a pe.
- Ceramic kiln furniture: Porous structure leh low thermal expansion formula inzawmkhawm; thermal cycling chak tak (thermal shock) a tuar thei.
- Chemical linings: Harsatna tihpun nan boron carbide dah belh a ni a; acid leh alkali laka service life chu a let thum in a ti rei.
