The application research of microwave equipment in the chemical industry is a new frontier interdisciplinary subject. The application of microwave equipment in chemical products can not only greatly save energy, but also complete several processes of some products in microwave equipment at one time. Many organic compounds cannot directly and visibly absorb microwaves, but they can use certain "sensitizers" that strongly absorb microwaves to transmit microwave energy to these substances to induce chemical reactions. Microwave plays an inductive role through the catalyst or its carrier, that is, the consumed microwave energy is used to induce the occurrence of catalytic reactions, which is called microwave induced catalytic reactions. In a microwave muffle furnace, samples can be melted and ashed, and some tgsin materials (commonly used sic) with high microwave absorption can be placed around the sample container. These materials can absorb 100% of the microwave, thereby raising the temperature in a short time. Compared to ordinary muffle furnaces, microwave muffle furnaces have faster heating rates for melting and ashing, and consume less energy. Using microwave muffles can also avoid thermal radiation when placing and removing samples. The main applications of microwave chemical product drying equipment include: glass fiber, chemical raw materials, starch cobalt oxalate, cellulose (such as hydroxyethyl cellulose, carboxymethyl cellulose, etc.), mannitol, nickel hydroxide, lithium cobalt oxide, graphite, carbon brush, silicon carbide, calcium chloride dihydrate, active carbon, zirconium oxychloride, zirconium oxide, zirconium hydroxide, zirconium carbonate, zirconium orthosulfate, ammonium zirconium carbonate, zirconium silicate, potassium zirconium carbonate, oily ink drying agent Waterborne ink cross-linked water repellent, expandable graphite, various ceramic zirconia, nano iron oxide, positive temperature coefficient (PTC) thermosensitive material ceramic components, honeycomb PTC components, etc.
