Plastic, Glass, Fiber, Foam, Thermal Testing Equipment Insulation Materials Thermal Insulation Efficiency Tester

1, Overview:
Thermal insulation efficiency and thermal conductivity system tester Thermal conductivity tester is based on the principle of unidirectional stable thermal conductivity. When the upper and lower surfaces of the sample are at different stable temperatures, the thermal flux passing through the effective heat transfer area of the sample and the temperature difference and thickness between the two surfaces of the sample are measured to calculate the thermal conductivity. Satisfied the high-precision testing requirements of the material testing research department for the thermal conductivity of materials. Instrument reference standards: GB/T3392-82 "Test method for thermal conductivity of plastics, thermal protection plate method", GB/T3139-2005 (Test method for thermal conductivity of fiber-reinforced plastics) (Test method for thermal conductivity of fiberglass reinforced plastic), GB/T10294 (Determination of steady-state thermal resistance and related characteristics of insulation materials - Thermal protection plate method), etc. Mainly testing plastic, glass, fiber, foam, thermal insulation materials and other materials. Widely used in material analysis and testing in universities, research institutions, quality inspection departments, and production plants.

2, Overall structure of the equipment
The equipment mainly consists of temperature control system, cylinder pressurization system, cooling system and other components.

2.1 Temperature Control System
Mainly composed of heating wires, iron plates, etc., heated by temperature instruments. The maximum heating capacity of the temperature zone can reach 700 degrees Celsius. For long-term use at 600 degrees Celsius, a total of 7 temperature acquisition channels are equipped. The heating temperature channel is a closed-loop control of the temperature zone, and 2 temperature measurement points are arranged on the other hot plate, hot surface, and cold surface.
2.2 Pressurization system
Mainly added by the cylinder, the required pressure value is achieved by fine-tuning the air pressure, and the current status is displayed in real-time in the control system.
2.3 Cooling system (optional, additional purchase of chiller)
Mainly composed of chillers, thermocouples, etc. The chiller cools the heating part of the equipment, and the thermocouple detects the bottom temperature. When the bottom temperature is greater than 40 ℃, the system prompts to "turn on the chiller".
