The use of hot and cold impact test cases
Hot and cold impact test box can not only use industry field, military items are available, and also can be a devastating mechanical equipment. Therefore, using the mechanical equipment is also very demanding. Before we use cold and hot shock test chamber, then try to understand what, and what need to be aware of when to use? Here let's go to know: 1, hot and cold impact test chamber before the test, protective coating layer sample cannot be cleared of organic coatings or coating, if I thing to compare big with coating on the fiber laser cutting out of the sample, are not allowed to damage optical fiber laser cutting area near the layered soil, preventing mixed. If it has a regulation, can? A proper use of stability under test standard to cover, such as paint, paraffin or tape, etc. , to maintain the cutting zone. 2 as far as possible, be tested samples before test carefully removed, thoroughly remove may damage the results of other impurity components. Is supposed to make the proper way, according to the characteristics of the specimen material in removal of specimen surface and remove other compounds, the clear specification does not allow use of compounds with a little bit of erosion. 3, before using hot and cold impact test cases need to ultrasonic cleaning machine with clean soft brush fire equipment and melting point in 60 ~ 120 & deg; C in the middle of hydrocarbons clear be tested samples. After clearing, with not using solvent cleaning sample, make it more and more dry. 4, hot and cold impact test chamber after sample clear, should use condom, block holds off, avoid being accidentally touch and air pollution. Destructive inspection can facilitate better use of hot and cold boxes, each side of it we all need to be careful to use, the use of hot and cold impact test chamber in addition more should pay attention to it in terms of key link, so only can ensure the use of mechanical equipment can be more strong. The above explanation is the hot and cold impact test cases of the use of information, hope can help you, if you want to learn more about information about hot and cold impact test chamber, welcome to the online consulting service or call the company service hotline for advice, we will wholeheartedly provide high quality service for you!
