Heating and drying of chemical products

1、 Characteristics of Microwave:

1. Linearity: Similar to visible light, it propagates in a straight line.

2. Reflectivity: When encountering a conductor such as a metal object, it reflects light waves like a mirror, and the metal does not absorb microwaves.

3. Absorption: It is easily absorbed by polar molecules (such as water) and converted into thermal energy.

4. Penetration: Microwaves are not absorbed by non-polar molecules (insulators such as ceramics, polypropylene, etc.), do not generate heat, but can penetrate these objects.

2、 Application of Microwave Drying Machine for Chemical Raw Materials in the Chemical Industry:

1. The study of microwaves in the chemical industry is an emerging interdisciplinary field. The application of microwave in chemical products can not only greatly save energy, but also complete several processes of some products in one microwave equipment. Many organic compounds cannot directly and significantly absorb microwaves, but can use a strong microwave absorbing "sensitizer" to transfer microwave energy to these substances and induce chemical reactions. Microwaves exert an inducing effect through catalysts or their carriers, that is, the consumed microwave energy is used to induce catalytic reactions, which is called microwave induced catalytic reactions. In a microwave muffle oven, samples can be melted and ashed, and materials 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 period of time (reaching a high temperature of 1000 ℃ within 2 minutes); Compared with ordinary muffle furnaces, microwave muffle furnaces have faster melting and ashing heating, and consume less energy. They can also avoid thermal radiation when placing and removing samples.

2. The main application objects of microwave drying machines for chemical raw materials 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, calcium chloride, activated carbon, zirconium oxychloride, zirconium oxide, zirconium hydroxide, aluminum hydroxide, aluminum oxide, aluminum oxide, zirconium trioxide, zirconium carbonate, zirconium sulfate, ammonium zirconium carbonate, zirconium silicate, potassium zirconium carbonate, oil-based ink drying agent, water-based ink cross-linking water resistance agent, expandable graphite, various resins, various ceramic zirconia, nano iron oxide, positive temperature coefficient (PTC) thermosensitive materials, ceramic components and honeycomb PTC components, and other chemical materials.
