Silicon carbide ceramic heat exchange module and manufacturing method thereof
The invention discloses a silicon carbide ceramic heat exchange module and a manufacturing method thereof. The silicon carbide ceramic heat exchange module is prepared by following steps: adding silicon carbide powder, nano carbon black, and boron carbide powder into a solution, premixing to obtain water base colloid with a total solid phase volume percentage of 30-50%; painting the water base colloid on the external wall of rod like expandable polymethyl methacrylate resin with a diameter of 10 to 20 mm, wherein the thickness of the colloid layer is 8-10 mm; arranging wrapped resins in one row to form a square plate with a single layer thickness of 26 to 40 mm; drying the surface of the square plate, rotating the single layer square plate in 90 degrees, stacking the square plates to forma cube, and finally sintering the cube at a temperature of 1500 to 2500 DEG C to obtain SiC ceramic with a density of 98% or greater. The provided module is suitable for a new air exchanger and can prolong the service life of the equipment.
本发明公开了一种碳化硅陶瓷热交换模块及其制造方法，所述碳化硅陶瓷交换模块是按照下述工艺制成：将碳化硅粉体、纳米炭黑和碳化硼粉体放置于溶液中预混合组合成总固相体积分数为30‑50％的水基胶体，再将水基胶体包裹在直径为10‑20mm的棒状可发性聚甲基丙烯酸甲脂树脂外壁，包裹厚度为8‑10mm，将包裹好的材料罗列摆放为一整排，使之成为单层厚度为26‑40mm的正方形平板，其表面干燥后，再将单层平板旋转90度后叠加摆放，形成正立方体，最后在1500‑2500℃固相烧结出致密度高于98％的SiC陶瓷，本发明的有益效果是，对于人们在一些特殊环境下使用新风交换器尤为的适合，且能够延长设备的使用寿命。
