Silicon carbide microchannel reactor preparation intermediate product and preparation method
According to the preparation intermediate product of the silicon carbide micro-channel reactor and the preparation method, the whole silicon carbide micro-channel reactor is prepared through one-time forming, fragmentation preparation and bonding processing are not needed, the processing technology is simple, the cost is extremely low, the rate of finished products is high, and the problem of liquid leakage between inner channels caused by uncertainty of bonding processing can be prevented; the micro-channel mold or the heat exchange channel mold is made of tin, lead, tin-containing alloy or lead-containing alloy, machining or casting forming is facilitated, the micro-channel mold or the heat exchange channel mold is embedded in silicon carbide green body powder and can bear high pressure, and a high-precision micro-channel or heat exchange channel can be conveniently formed in a green body; after tin, lead, tin-containing alloy or lead-containing alloy are melted, the tin, lead, tin-containing alloy or lead-containing alloy has good fluidity, cannot permeate into the silicon carbide green body, and can be easily discharged from the liquid inlet/outlet.
本发明提出了一种碳化硅微通道反应器制备中间品及制备方法，一次成型制备出整个碳化硅微通道反应器，无需分片制备再键合加工，加工工艺简单、成本极低、成品率高，且能防止因键合加工的不确定性导致的内通道间漏液问题；采用锡、铅、包含锡的合金或者包含铅的合金制作微通道模具或换热通道模具，便于加工或者浇铸成型，且预埋在碳化硅生胚粉体中可以承受高压，便于在生胚内形成高精度微通道或换热通道；锡、铅、包含锡的合金或者包含铅的合金在熔化后，有很好的流动性且不会渗透到碳化硅生胚内部，非常容易从进出液口排出。
