　　2.2.2 Specially designed dual protection safety furnace door, multi-layer composite integrated high-strength anti radiation leakage furnace door, explosion-proof, shock wave resistant, microwave leakage prevention and other safety performance;

2.3 Temperature and pressure control system

*2.3.1 Adopting high-precision PTone000Contact temperature sensor, detection frequency: 150-200 data/second;Rate of warming:Reach the target temperature at a constant speed within the set time. Temperature sensor range: 0-300 ℃; Temperature measurement accuracy: ± 0.1 ℃; Temperature control accuracy ± 1 ℃;

*2.3.2 High precision contact pressure sensors are used to measure the actual pressure of the reactants, rather than calculated values such as water line pressure measurement, and to avoid the influence of errors caused by piezoelectric crystal pressure measurement methods and internal tank shape changes;Pressure sensor range: 0-10MPa; Pressure control range: 0~tenMPa； Measurement accuracy ≤ ± 0.01Mpa; The precision of pressure control is ≤± 0.05Mpa.

two point four Multi flux digestion rotor:

*2.4.1 The pressure resistant jacket is made of fully imported high-strength aerospace composite material PEEK, which is die cast as a whole and can withstand high temperature and high pressure; Operating Temperature≥2five0℃Work pressure≥fiveMpa；

*2.4.2 The tank rack adopts a petal shaped frame structure, which is injection molded from composite materials and has strong pressure bearing capacity; Equipped with 10 digestion rotors for easy loading and unloading; The digestion process does not require any consumables;

　　2.4.3 The inner tank is made of molded modified polytetrafluoroethylene material, which has good density and good safety performance without micropores; Good mechanical properties and creep resistance, the sample can be directly weighed on a balance without the need for transfer steps;

　　2.4.4 Explosion proof design: Vertical directional blasting design of the tank body to avoid lateral impact;

two point fiveCooling system:

　　2.5.1 Cooling method: Forced rapid air cooling inside the furnace chamber, using corrosion-resistant, high air volume centrifugal fans with an exhaust volume of ≥ 4M3/min. After the reaction is complete, the microwave stops emitting, and the turntable and fan continue to work. After the temperature inside the tank cools to 40 ℃, the instrument automatically beeps to remind;

2.6 Software Control System

*2.6.1Equipped with AndroidoperationsystemfiveInch color LCD capacitive touch screen, quad core 1.2GHz processor,oneGB of running memory,eightG memory, USB interface, real-time display of temperature, time, microwave power, pressure values and curve graphs in the reaction system. The instrument can be set up in 20 reaction stages step by step, and there is no limit to storing reaction data sets;

*2.6.2Randomly equipped with upper computer software for replaying experimental data, it can be connected to the PC upper computer in real time through a local area network (WiFi), remotely viewing real-time experimental parameters such as temperature, pressure, microwave power, etc., for easy analysis of experimental results. The software will also alarm for abnormal situations and remotely shut down the instrument. equipped withDevice, inofflineRemote stop of response in emergency situations;
