A quality inspection method for home furnishing board materials according to claim 1, characterized in that: The colorimetric instrument described in step six can complete the image analysis of the sample plate, and use image processing technology and software analysis to complete the detection of color distribution and differences on the surface of the plate.

7. A quality inspection method for home furnishing board materials according to claim 1, characterized in that: The bending resistance test described in step seven adopts one of the four-point bending method or the three-point bending method, and its specific operation is as follows: place the plate between the fulcrums, apply a vertical load on the fulcrum side, and the bending resistance test of the plate can be completed.

8. The quality inspection method for home furnishing board material according to claim 1, characterized in that: The hardness test described in step seven mainly adopts the Barcol hardness test method combined with the scratch resistance test, and the specific operation is as follows: apply pressure to the surface of the sample plate, and test the indentation diameter to calculate the hardness value; then use a standardized tester to simulate the scratching situation that the sample plate may encounter during use, and complete the record.

9. A quality inspection method for home furnishing board materials according to claim 1, characterized in that: The specific detection steps of the combustion device detection in step eight are as follows: Step 1: During the test, the rotating shaft (402) is engaged with the shaft hole (301) so that the door body (4) can be opened; Step 2: clamp the upper and lower ends of the sample plate between the receiving grooves (601), and insert the fixing screw into the screw hole (604) to complete the fixing of the sample plate, and then close the door (4); Step 3: Control the movement of the ignition element (7) through the external control end, and after igniting both sides of the sample plate, through the glass window (401), the upper and lower ends of the sample plate are relatively fixed during the combustion process, and the flame spreading speed and the combustion degree of the sample plate can be observed through the burning speed of the middle part; Step 4: The hot gas smoke generated during the combustion process is discharged through the smoke outlet (5), and the harmful gas components in the hot gas smoke are detected by the harmful gas detector (501). The heat released when the sample plate is burned can be detected by detecting the temperature of the hot gas smoke, so as to evaluate the combustion speed and heat release rate of the sample plate in the fire; The toxic gases produced during the combustion process are analyzed to determine their types, components and concentrations.
