Application of low/high Temperature Test Chamber in high-low temperature resistance test of plasticizers

Plasticizer is an additive widely used in plastic products, which can improve the flexibility and toughness of plastic, and improve its processing performance and molding performance. The high-low temperature resistance test is to verify the durability and stability of the plasticizer at extreme temperatures. In a high temperature environment, the plasticizer may decompose or volatilize, causing the plastic product to harden or become brittle, while in a low temperature environment, the plasticizer may lose its effect, making the plastic product easy to break or crack. Through the high-low temperature resistance test, the durability and stability of plasticizers under different temperature environments can be evaluated, and high-quality plasticizers can be provided for the production of plastic products to ensure the performance and reliability of products in various extreme environments.

The high-low Temperature Test Chamber can be used in the high-low temperature resistance test of plasticizers to test the physical properties and chemical stability of plasticizers in high-low temperature environments. The following are the test steps of the high-low Temperature Test Chamber in the high-low temperature resistance test of plasticizers:

1. Preparation: Check whether the Test Chamber and temperature controller are working normally, and set the temperature range and heating and cooling rate of the Test Chamber according to the test requirements. Prepare the plasticizer to be tested, and pay attention to its model and technical parameters.

2. Sample installation: Install the plasticizer sample to be tested on the sample holder in the Test Chamber, and pay attention to its position and direction, so as to ensure the accuracy of the test results.

3. Test operation: Turn on the Test Chamber and temperature controller, and set the temperature range and heating and cooling rate of the Test Chamber. Raise the temperature of the Test Chamber to the set temperature range, keep it for a period of time, and then cool down to the set temperature. During the test, record the temperature change inside the Test Chamber, and record the physical properties and chemical stability of the plasticizer.

4. Evaluation of test results: After the test, the plasticizer is inspected and tested, including the test and evaluation of its physical properties and chemical stability. Through the evaluation of the test results, the tolerance and stability of the plasticizer in high-low temperature environments can be judged.

Beichao reminds you: before the test, the plasticizer should be checked and tested to ensure that it is normal. During the test, the temperature range and heating and cooling rate inside the Test Chamber should be strictly controlled to ensure the accuracy and reliability of the test. At the same time, the Test Chamber should be cleaned and maintained after the test to prolong its service life.
