Silicon carbide (SiC) heat exchanger hi chemical, energy, leh environment humhalh kawngah te hman a ni nasa hle a, a chhan chu high-temperature resistance tha tak, corrosion resistance, leh thermal conductivity sang tak a nih vang a ni. Mahse, an performance hi material thlan danah a innghat nasa hle a, material combination dik tak chuan equipment service life leh operating efficiency direct-in a nghawng a ni.
Pakhatnaah chuan core heat exchanger components siamna atana hmanraw duh ber chu silicon carbide ceramic a ni. High-purity silicon carbide (eg, 98% aia sang) hian bawlhhlawh a nei tlem hle a, hei hian thermal shock resistance leh chemical stability nasa takin a ti tha a, hei hian acid chak tak leh base ang chi corrosive media awmna environment atan a tha hle.
