Low/high Temperature Test Chamber for high-low temperature resistance test of lignin fiber

Lignocellulosic fiber is a kind of polymer compound, which may undergo physical and chemical changes under different environmental conditions, thereby affecting its performance and stability. In practical applications, lignin fibers may need to withstand extreme environments such as high temperature and low temperature. For example, processing processes such as hot pressing and thermal curing are required when preparing composite materials. Therefore, in order to ensure that lignin fiber can maintain its performance and stability in different environments, it is necessary to conduct high-low temperature resistance tests to evaluate its mechanical properties and chemical stability at different temperatures, so as to ensure its practical application. reliability and stability.

The high-low Temperature Test Chamber can be used for high-low temperature environmental testing of lignin fiber to verify its stability and performance under extreme temperature conditions. The following is the application and test procedures of the high-low Temperature Test Chamber in the high-low temperature resistance test of lignin fiber.

application

The application of the high-low Temperature Test Chamber in the high-low temperature resistance test of lignin fiber includes:

• High temperature test: place lignin fiber in a high temperature environment to simulate high temperature climate conditions and test the thermal stability and heat resistance of lignin fiber.

• Low temperature test: put the lignin fiber in a low temperature environment to simulate cold climate conditions, and test the cold resistance and softness of the lignin fiber.

• Temperature cycle test: place the lignin fiber in a high-low temperature cycle environment to simulate the temperature change and test the deformation and damage of the lignin fiber.

experiment procedure

The test steps of the high-low Temperature Test Chamber in the high-low temperature resistance test of lignin fiber are as follows:

1. Preparation: Put the lignin fiber to be tested into the high-low Temperature Test Chamber. Before placing, it is necessary to ensure that the lignin fiber has been expelled from residual heat or moisture, and anti-static measures should be taken.

2. Set test conditions: Set test conditions for high temperature, low temperature or temperature cycle according to actual needs. These conditions include temperature range, rate of temperature change, soak time, etc.

3. Start the test: Start the high-low Temperature Test Chamber according to the set conditions and start the test. During the test, the high-low Temperature Test Chamber will automatically control the temperature and perform high-low temperature cycles within the set temperature range.

4. Monitoring: During testing, lignocellulosic fibers need to be monitored to ensure their performance in high-low temperature environments. The monitoring parameters include the morphology, mechanical properties, and molecular structure of lignin fibers.

5. End the test: When the test is completed, close the high-low Temperature Test Chamber and take out the test equipment. Data analysis and evaluation is then carried out.

In summary, the high-low Temperature Test Chamber is a very effective testing device that can be used to verify the durability and performance of lignocellulosic and other materials under extreme temperature conditions.
