Introduction: The working principle of the microwave ashing furnace is to use microwave as the heating source to heat up, and the sample processing process of carbonizing and ashing the material can be completed under high temperature conditions. The combination of the "high energy" of the microwave and the high concentration of oxygen in the gas stream makes the ashing time of the sample change from the traditional "hour" to "minute", which greatly improves the working efficiency. At the same time, the sample can continuously complete the microwave carbonization and ashing in one process, and improve the cumbersome operation brought by the traditional carbonization and ashing steps. Application field: Suitable for ashing, sulfonation and melting of various organic and inorganic substances. , drying, wax burning, fusion, heat treatment and burning residue, loss on ignition, chemical analysis, gravimetric analysis, etc.; widely used in traditional Chinese medicine, health products, biological samples, graphite, coal, coking products, chemical raw materials Other non-metallic substances such as coke ash (fast ash and slow ash), volatile matter measurement. Features: 1. Fast: The ashing time is converted from "hours" to "minutes"; 2. Accuracy: Adopt advanced microwave power and temperature automatic adjustment control technology to achieve non-pulsating microwave continuous heating, so that the heating process is stable; microwave energy is on, without thermal inertia, easy to control temperature; 3. Microwave and auxiliary heat two-in-one: microwave heating and auxiliary heating work together, and the ashing is more complete and more uniform; 4. Airflow: unique down-pressure airflow design, single-channel atmosphere control pipeline, which can pass oxygen, nitrogen, inert protective gas, etc. 5. Safety: multiple interlocking structure of door body, open door and power off, protect operators, microwave leakage protection conforms to national standard 6.Special furnace structure can be customized according to experimental requirements Technical Parameters: 1. Power supply: 220V ± 10%, 50Hz; 2. Microwave system Power: 0 ~ 1600W continuously adjustable, automatic frequency conversion microwave output Frequency: 2450±50MHz 3. Temperature system Temperature measurement method: thermocouple temperature measurement is 0-1200 ° C Working temperature: 100～1200°C Limit temperature: 1200 °C Temperature measurement accuracy: ±1 °C 4. Inner cavity material: the inner cavity material is made of special high temperature ceramic fiber Control mode: using touch screen display, PLC intelligent control system, convenient setting and real-time curve display temperature, time, power parameters; automatic, manual, constant temperature mode; 50 kinds of process parameters can be stored, with USB interface can export historical data, Easy to analyze data; and can achieve program gradient heating or rapid temperature rise 5.
