The structure and material composition of the salt spray test box
The structure and material composition of the salt spray test box Salt fog refers to the dispersion system composed of tiny droplets containing salt in the atmosphere, which is one of the three types of artificial environment protection series. Many enterprise products need to simulate the destructive effect of ocean surrounding climate on products. Salt fog test is to simulate the generation of this phenomenon. Salt spray test box what is salt spray test box Salt spray test box Salt spray test is divided into neutral salt spray test and acid salt spray test. The difference lies in th...

How to control humidity in constant temperature and humidity test box
Constant temperature and humidity box refers to the specified temperature and humidity of the product. For the high temperature and low temperature resistance of the product, as well as the ability to resist humidity, the constant temperature and humidity test box is capable of lowering temperature and humidity at the same time. The temperature of the test chamber every small make up emphasis is especially important, temperature for test, as a component factors lead to test result, in the constant temperature and humidity test chamber, the product into the box will be in accordance with the...

What should be paid attention to in standby state of high and low temperature test box
Pull out the switch power connector of the high and low temperature test box, save and put it well. Remove the test products from the box and clean the dirt in the working room. Use instructions, certificates and other materials to prevent moisture. The sealing strip of the high-low temperature test box is cleaned with cloth, coated with talcum powder for maintenance or padded with plastic paper at the contact place between the door seal strip and the shell, to prevent long-term closure and cause the problem of door frame adhesion. Rapid temperature change test chamber Switch the b...

Different principles of tensile testing machine
Testing principle of tensile testing machine Tensile testing machine stretching speed mainly for stretching, break elongation, the influence of the yield strength. The influence of the tensile testing machine speed varies with the material, so do the tensile test should be carried out strictly in accordance with relevant provisions of the standard test method for speed test, otherwise it will affect the accuracy of the test results. Tensile strength: tensile strength increases with the increase of test speed, but tends to be stable after reaching a certain stage. The faster the test spee...
