Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, and particularly to a testing device for the flame retardant performance of flame retardant materials. Background Technique

[0002] The flame retardant performance detection device is developed according to international and national standards, and is a laboratory device specially used to evaluate the flame retardant performance of various materials. Such devices are mainly used to simulate the combustion characteristics of materials in a fire environment, and then analyze their flame retardant capabilities. The application fields of flame retardant performance detection devices are very wide, covering many industries such as textiles, foam plastics, rubber, fire doors, coal mine supplies, fire retardant coatings, etc., as well as major quality inspection units. Commonly used flame retardant detection equipment includes vertical flame retardant meters, fabric horizontal flame retardant meters, oxygen index meters, etc., and these devices play a crucial role in flame retardant performance testing.

[0003] The vertical burning method is a common and important testing method in flame retardant performance testing, mainly simulating the fire situation in the vertical direction to evaluate the flame propagation, self-ignition and dripping of materials. In flame retardant performance detection, the dripping of the sample during combustion is a phenomenon that needs to be focused on. The dripping phenomenon may not only exacerbate the spread of the fire, but also cause secondary harm to personnel and property. Therefore, in flame retardant performance detection, the evaluation of the dripping of the sample during combustion is of great significance.

[0004] In the prior art, in order to simulate the fire situation vertically upward, the burner is usually arranged below the bracket for fixing the sample. This up-and-down structure setting has the risk that the dripping object falls on the burner, which will damage the burner, affect the service life of the equipment, and the dripping objects generated by combustion are not easy to clean.
