Second, GDW-100 high and low temperature test chamber box structure:
Equipment shell: It is made of high-quality A3 steel plate CNC machine tool, the surface of the shell is sprayed, and it is bright and beautiful. The material is SUS304 high-quality stainless steel plate insulation material: high-density glass fiber cotton, the thickness of insulation is 80mm, so the indoor temperature is not It will be conducted to the outside of the device to ensure a stable temperature observation window in the laboratory: a transparent window is placed at a reasonable position to observe changes in the indoor sample. The observation window adopts multi-layer hollow tempered glass and inner glued sheet type conductive film, which has the advantages of transparency, heat insulation, and difficulty in generating steam frosting. The long-axis fan motor and the high-low temperature resistant stainless steel multi-wing impeller are mandatory. Convection vertical diffusion cycle, uniform temperature and humidity in the laboratory and maintain stable lead holes (left side of the machine) can be used for external test power line or signal line (diameter 50mm)
The control part of the equipment is designed on the right side of the equipment, distributed with temperature controller, control switch, etc., easy to operate, simple and easy to maintain.
Third, GDW-100 high and low temperature test chamber control system:
Temperature control instrument adopts (Japan RKC) imported digital display high precision integrated controller Accuracy: 0.1 °C (display range)
Temperature sensor: PT100 platinum resistance temperature measuring body control mode: heat balance temperature control mode temperature control adopts P·I·D+S·S·R system co-channel coordinated control with automatic calculation function, which can immediately correct temperature change conditions and make temperature control More accurate and stable data and test conditions, the controller has a locking function to avoid human touch and change the test results.
Fourth, GDW-100 high and low temperature box refrigeration system:
Compressor: fully enclosed France Taikang;
Refrigeration mode: double-machine cascade refrigeration;
Condensation mode: forced air cooling;
Refrigerant: R404A, R23 (environmentally friendly);
The whole system pipeline is tested for ventilation and pressure 48H leak test;
The heating and cooling system is completely independent;
Inner spiral refrigerant copper tube;
Dry filter, refrigerant flow window, repair valve, oil separator, solenoid valve, and liquid storage tank are all imported original parts.
Five, GDW-100 high and low temperature test chamber use conditions:
Ambient temperature: 5 ° C ~ +28 ° C (average temperature within 24 hours ≤ 28 ° C)
Ambient humidity: ≤85% RH
Power requirements: AC380 (±10%) V / 50HZ three-phase five-wire system

Calcium carbonate is a kind of inorganic compounds, chemical formula optimization for CaCO ₃, commonly known as grey stone, limestone, limestone, marble, etc. Calcium carbonate is neutral, basically insoluble in water, soluble in hydrochloric acid. It is one of the common substances on the earth. It exists in aragonite, calcite, chalk, limestone, marble, travertine and other rocks. It is also the main component of animal bones or shells. Calcium carbonate is also an important building material and is widely used in industry.
