The test apparatus for the flame retardant test method of building materials is used for the determination of the flame retardant performance of building materials, mainly including two parts: burning shaft furnace and testing equipment.1. Construction material burning shaft furnaceThe building material burning shaft furnace is mainly composed of burning chamber, burner, test piece support, air steady flow layer and flue and other parts. Its overall dimensions are 1020mmX1020mmX3930mm.
1. Burning chamber The burning chamber is composed of a furnace wall and a furnace door, and its inner space size is 800mmX800mmX2000mm. The furnace wall is an insulating interlayer structure, and its structural form. The furnace door is divided into upper and lower doors, which are respectively connected to the furnace body by hinges, and its structure is similar to that of the furnace wall. The two doors are closed with the furnace body by means of hand wheels and fixed screws. There are observation windows on the upper furnace door and the rear wall of the burning chamber. 2. BurnerThe burner is placed horizontally in the center of the burning chamber, 1000mm from the bottom of the furnace. 3. Specimen supportThe specimen support is a rectangular parallelepiped frame with a height of 1000mm, and the four sides of the frame are provided with screw rods for adjusting the installation distance of the specimen, and the frame is made of angle steel.
