specific Embodiment approach

[0024] A method for producing formaldehyde-removing flooring, the steps are as follows:

[0025] A. Raw materials are put into the warehouse; before raw materials are put into the warehouse, first check whether the wear-resistant paper, pattern paper, substrate, and balance paper are qualified, and deal with unqualified ones, and put the qualified ones into the warehouse.

[0026] B. Pressing and pasting; the specific steps of pressing and pasting are as follows:

[0027] a. Install the upper and lower steel plates, and then adjust the temperature of the upper and lower steel plates. The temperature of the upper steel plate is 180-190 degrees, and the temperature of the lower steel plate is 200-210 degrees.

[0028] b. Spray Chinese herbal medicine to remove formaldehyde liquid:

[0029] First, two workers use spray guns to spray 300 ml of liquid medicine evenly on the density board of 2465x1263x12 mm.

[0030] Then roll up the balance paper and put it on the conveying table...
