[0002] Fire retardant coating is a coating that is applied to the surface of a material to improve the material's fire resistance, slow down the spread of flames, or prevent combustion within a certain period of time. This type of coating is called fire retardant coating, or flame retardant coating. After the fire retardant coating is produced, its fire resistance level needs to be tested. The main operating procedure of the rating is to burn the decorative refractory board movement with flames in different temperature zones. If there is no damage within a specific period of time, it meets the rating standards.

Two symmetrical upper cover connecting plates 2 are arranged at the top of the square test shell 1. Contact switch strips 6 are fixedly installed on the front of the two upper cover connecting plates 2. Two timers 5 corresponding to the upper cover connecting plates 2 are arranged on the top side of the square test shell 1. The contact switches of the two timers 5 are respectively squeezed and connected with the corresponding contact switch strips 6. Gas flamethrowers 15 are installed inside the left test area and the right test area; the two gas flamethrowers 15 are connected to the gas pipeline arranged at the bottom of the square test shell 1, and the gas pipeline is connected to an external gas source.

[0021] The above structural design: the servo drive motor 13 can change the channel opening of the flow adjustment seat 12 after being powered on, so as to facilitate the adjustment of the air volume, so that the left test area and the right test area can burn more completely, avoiding insufficient oxygen inside the square test shell 1 causing incomplete combustion and reducing the test effect.

[0022] In the above embodiment, in order to better observe the test conditions of the left test area and the right test area and facilitate better recording, circular tempered glasses 7 are provided on both sides of the front of the square test housing 1, and the two circular tempered glasses 7 correspond to the left test area and the right test area respectively.

[0023] like Figure 3 As shown, in the above embodiment, in order to better limit the fire retardant coating (the fire retardant coating is solidified first during the test), heat-resistant connecting strips 17 are provided at the bottom ends of the two upper cover connecting plates 2.
