Description

Technical Field

[0001] The utility model relates to the field of product R & D, in particular to a flame retardancy testing device with high safety. Background Technique

[0002] Flame retardant glue is an inorganic polymer adhesive formed by high-temperature and high-pressure polymerization of inorganic raw materials such as aluminum phosphate, magnesium silicate, sodium silicate, fire retardant, and inorganic polymer aggregating agent. It is mainly used for various structural bonding and sealing in industrial production. It is a non-flammable bonding and sealing material. Before launching new products, merchants also need to test their performance, find problems and correct them to ensure the performance of the products.

[0003] During the process of testing products, mainly open flames are used to burn the test products to test their performance. However, during the use of open flames, there are often certain dangers. Moreover, for soft products such as flame retardant glue, they also need to be applied on a carrier for testing. When loading, the side coated with the test product needs to face the flame nozzle. After the test is completed, it needs to be turned over to observe the test results, which is rather troublesome. Therefore, the utility model provides a flame retardancy testing device with high safety to solve the problems raised in the above background technique. Content of the Utility Model
