I. Unique Microwave Heating Method:

Microwave Heating Mechanism: Microwaves are a form of electromagnetic waves. Under the influence of a high-frequency electromagnetic field, polar molecules in dielectric materials realign from their random distribution to follow the polarity of the electric field. These polar molecules transition from thermal motion to aligning with the alternating microwave electromagnetic field, generating intense friction and heat. Microwave energy is converted into thermal energy within the medium, leading to a macroscopic temperature rise—this is the fundamental principle of microwave heating. As a non-contact internal heating method, microwave heating causes the material itself to heat uniformly. Electromagnetic energy directly acts on molecular dipoles, converting into heat, and the penetrating nature of microwaves allows simultaneous heating of both internal and external parts of the material without relying on heat conduction. The lack of internal heat dissipation results in a temperature gradient where the interior is hotter than the exterior, creating a pressure differential that drives heat or moisture toward the surface. In contrast, conventional electric furnace heating relies on thermal radiation, convection, and conduction, transferring heat from the outside in. This method suffers from high heat loss, low energy efficiency, slow heating rates, uneven and sluggish heat distribution, and a tendency for coking. Scaling up industrial electric furnaces increases exhaust gas treatment volume, requires extensive kiln infrastructure, operates in rough production environments, and necessitates regular furnace cleaning, shutdowns for maintenance, part replacements, and costly, time-consuming repairs.

II. Role of Microwave Experimental Furnaces in Enterprise and Research Institute Testing:

Microwave heating, being a non-contact internal method, enables the material to heat uniformly from within. Microwave heating technology offers rapid heating speed, selectivity, catalytic properties, non-direct contact between the heat source and material, ease of automation, and energy savings. Thus, the microwave experimental furnace is a standardized, multi-functional high-temperature microwave experimental equipment. It is simple to operate, highly efficient, and greatly facilitates experimental exploration of various materials and scientific process determination. It is primarily suitable for experiments on metal oxides, non-metallic materials, polymer materials, electronic ceramic powders, power battery materials, molecular sieves for petrochemicals, industrial new materials, and other powders and products. It can operate with protective gases, weakly reducing gases, air, oxygen-enriched air, and under slight positive pressure. It features fast calcination speed, high efficiency, and broad application fields.

Microwave experimental furnace equipment is applicable in organic synthetic chemistry, pharmaceutical chemistry, food science, inspection and epidemic prevention, industrial chemistry, molecular biology, analytical chemistry, inorganic chemistry, petrochemicals, materials science, biomedical science, and related fields. The instrument holds significant application value in these areas, using enthalpy and entropy effects to induce or accelerate chemical reactions and physical processes, speeding up reactions hundreds to thousands of times compared to conventional methods, while improving reaction selectivity and yield. This makes many previously difficult or slow reactions achievable and rapidly completable. It is mainly used in universities, research institutes, and enterprise R&D centers for high-temperature sintering with atmosphere, research, and small-batch production of various non-metallic materials.

Advantages of the Microwave Multi-functional Experimental Furnace:

1. High Production Efficiency: Based on the overall microwave heating mechanism, the microwave experimental furnace heats up quickly, 5-20 times faster than traditional electric heating furnaces. Its insulation system has low heat capacity, so it also cools down faster, meeting the demands of rapid and efficient experiments.

2. Superior Product Quality: Uniform microwave heating ensures high product quality.

3. High Energy Utilization: Saves over 50% energy compared to electric heating furnaces.

4. Saves Experimental Time: Most high-temperature calcination tests can be done 2-3 times per day, with low-temperature drying taking 10-30 minutes per cycle. Technicians don’t need to work overtime; experimental data is automatically saved, significantly aiding in feasibility exploration of materials, process direction determination, and process curve adjustment.

III. Distinct Features of Microwave Experimental Furnace Compared to Resistance Furnaces:

Microwave heating offers fast heating speed, selectivity, catalytic properties, non-direct contact between heat source and material, ease of automation, and energy savings. Microwave experimental equipment is energy-efficient (high conversion to thermal energy, saving over 30% compared to traditional heating), environmentally friendly (no emissions, reduces harmful substances), clean (material heats by absorbing microwaves, no contact pollution, improves product quality and yield), and highly efficient (fast heating, high energy utilization). Additionally, ZhongSheng's microwave industrial equipment reaches temperatures up to 1600°C with kiln temperature stability of ±5°C, saving time, being efficient, simple to operate, convenient, and meeting frequent testing needs.

1. Integrated and Portable: The microwave furnace and control system are integrated, mounted on a mobile frame for easy operation, flexibility, and small footprint.

2. Continuously Adjustable Microwave Output Power: Single microwave source adjustable from 0.1 to 1.48 KW, ensuring stable temperature control.

3. High Static Ultimate Vacuum: <50 Pa.

4. Complete Atmosphere Protection: Suitable for protective gases, weakly reducing gases, air, oxygen-enriched gases, etc. Atmosphere enters the furnace chamber through two paths—one directly into the crucible, the other between the chamber and insulation—overcoming the flaw in similar products where protective atmosphere fills the insulation but not the crucible.

5. Wide Low-Temperature Detection Range: Detects from 0°C to 1800°C, addressing the limitation of similar products that cannot detect or control below 450°C.

6. Simple Cooling Water System: Includes a standard circulating water chiller for easy installation, debugging, and use.

7. Excellent Microwave Energy Feed Matching: Uses industrial microwave sources with diffuse reflection in the chamber, ensuring uniform microwave field and no hot spots during high-temperature material processing.

8. Simple Operation and User-Friendly: PLC + touch screen control, built-in USB port for automatic data storage to USB drive. PLC has RS232 or RS485 interfaces for PC communication, multiple temperature control curves, and dual automatic/manual heating functions. Optional single or dual magnetron operation for energy savings.

9. Safe and Reliable: Equipped with industrial water-cooled microwave source system, special microwave shielding seals, microwave leakage far below national standard (<0.2 mW/cm2), with anti-leakage alarm and safety lock. Automatically or manually cuts off microwave source if leakage exceeds limits.
