Embodiment 1
[0033] The process of pressing and pasting melamine-impregnated paper on the surface of the inorganic board in this embodiment comprises the following steps:
[0034] (1) Smooth the inorganic board through 180-mesh sanding, clean the surface dust, and control the moisture content of the inorganic board to 5%;
[0035] (2) cutting the polymer film into a size consistent with the specifications of the inorganic board, then superimposing the inorganic board and the polymer film, with the smooth side of the polymer film facing upwards, to obtain the assembly A;
[0036] (3) The polymer film and the melamine-impregnated paper are superimposed, and the smooth side of the polymer film faces downward to obtain the assembly B;
[0037] (4) Superimpose the blank group B on the blank group A to form a pre-pressed plate, put the pre-pressed plate in the hot press for heating and pressing, the temperature is 150°C, the pressure is 12Mpa, heating and pressing The pressing time is 40 second...
Embodiment 2
[0039] The process of pressing and pasting melamine-impregnated paper on the surface of the inorganic board in this embodiment comprises the following steps:
[0040] (1) Smooth the inorganic board through 180-mesh sanding, clean the surface dust, and control the moisture content of the inorganic board to 5%;
[0041] (2) Cutting the polymer film into a size consistent with the specifications of the inorganic plate, superimposing the inorganic plate and the polymer film, with the bright side of the polymer film facing up, to obtain the assembly A;
[0042] (3) The polymer film and the melamine-impregnated paper are superimposed, the smooth side of the polymer film faces downward, and the blank B is assembled;
[0043] (4) Superimpose the blank assembly B on the blank assembly A to form a pre-pressed plate, put the pre-pressed plate in the hot press for heating and pressing, the temperature is 160°C, the pressure is 14Mpa, heating and pressing The pressing time is 30 seconds. ...
Embodiment 3
[0045] The process of pressing and pasting melamine-impregnated paper on the surface of the inorganic board in this embodiment comprises the following steps:
[0046] (1) Smooth the inorganic board through 180-mesh sanding, clean the surface dust, and control the moisture content of the inorganic board to 5%;
[0047] (2) cutting the polymer film into a size consistent with the specifications of the inorganic board, then superimposing the inorganic board and the polymer film, with the smooth side of the polymer film facing upwards, to obtain the assembly A;
[0048] (3) The polymer film and the melamine-impregnated paper are superimposed, and the smooth side of the polymer film faces downward to obtain the assembly B;
[0049] (4) Superimpose the blank group B on the blank group A to form a pre-pressed plate, put the pre-pressed plate in the hot press for heating and pressing, the temperature is 150°C, the pressure is 12Mpa, heating and pressing The pressing time is 25 second...
