LFY-666 Thermal conductivity and compression and heat resistance tester for protective clothing
The main purpose
It is used to test the thermal conductivity and compression heat resistance of woven fabrics, knitted fabrics, cotton wool, sheets and composite materials with thermal insulation properties.
Instrument characteristics
1. It has a constant temperature heating system that can stably control the temperature to room temperature to (400±0.5) ℃;
2. The copper calorimeter with high precision and timeliness temperature measurement meets the test accuracy requirements;
3. With copper calorimeter in place automatic judgment system
4. The dedicated data collection and automatic control system can display the temperature rise curve on the back of the sample, the pain curve of human tissue and the second-level burn curve in real time.
Technical parameter
1. Heating plane: the size is at least 200mm×200mm, and the heating temperature range is room temperature～(400±0.5)℃;
2. Thermal conductive plate: size 140mm×140mm×6.4mm, built-in temperature sensor;
3. Copper calorimeter: a copper sheet with a mass of 18.0g and an exposed area of 12.57cm2, with a total of 4 J-type thermocouples riveted in 120° on the top and riveted in the center;
4. Sample size: (100±2)mm×(150±2)mm;
5. Exposure temperature: test temperature (280±0.5)℃; calibration temperature (200±0.5)℃;
6. Contact pressure: 3kPa;
7. Exposure time accuracy: ±0.1s;
8. Power supply: 220V, 50Hz.
