Embodiment 1
[0073] Embodiment 1: the preparation method of jaw plate, comprises the steps:
[0074] 1. First prepare a vanadium plate 1, wherein the purity of vanadium should be controlled at 99.7%. The vanadium plate 1 should be surface treated first, and the steps are as follows:
[0075] The first step is pickling, choose 300ml / L hydrochloric acid, and then rinse with running water;
[0076] In the second step of pickling, choose 300ml / L hydrofluoric acid, and then rinse with running water;
[0077] The third step is surface grinding, using 800 mesh Al 2 o 3 Sandpaper and finally ultrasonic cleaning with alcohol. The thickness of the vanadium plate 1 is controlled at 0.2 mm.
[0078]2. According to the size of the jaw plate 2, the jaw plate mold 3 is made of polystyrene foam. According to the working force of the jaw plate 2, the main wear part is the working surface of the jaw plate 2 in contact with the material. According to this, the vanadium The plate 1 is fixed on the surfa...

[0087] Embodiment 2: the preparation method of jaw plate, comprises the steps:
[0088] 1. First prepare a vanadium plate 1, wherein the purity of vanadium should be controlled at 99.8%. The vanadium plate 1 should be surface treated first, and the steps are as follows:
[0089] The first step is pickling, 60ml / L phosphoric acid, and then rinse with running water;
[0090] The second step is pickling, 200ml / L sulfuric acid, and then rinse with running water;
[0091] The third step is surface grinding, using 1000 mesh Al 2 o 3 Sandpaper and finally ultrasonic cleaning with alcohol. The thickness of the vanadium plate 1 is controlled at 1mm.
[0092] 2. According to the size of the jaw plate 2, the jaw plate mold 3 is made of polystyrene foam. According to the working force of the jaw plate 2, the main wear part is the working surface of the jaw plate 2 in contact with the material. According to this, the vanadium The plate 1 is fixed on the surface of the jaw plate mold ...
Embodiment 3
[0101] Embodiment 3: the preparation method of jaw plate, comprises the steps:
[0102] 1. First prepare a vanadium plate 1, wherein the purity of vanadium should be controlled at 99.8%. The vanadium plate 1 should be surface treated first, and the steps are as follows:
[0103] The first step is pickling, 120ml / L hydrogen peroxide, and then rinse with running water;
[0104] The second step is pickling, 240ml / L hydrogen peroxide, and then rinse with running water;
[0105] The third step is surface grinding, using 1000 mesh Al 2 o 3 Sandpaper and finally ultrasonic cleaning with alcohol. The thickness of the vanadium plate 1 is controlled at 0.35mm.
[0106] 2. According to the size of the jaw plate 2, the jaw plate mold is made of polystyrene foam. According to the working force of the jaw plate 2, the main wear part is the working surface of the jaw plate 2 in contact with the material. According to this, the vanadium plate 1 is fixed on the surface of the jaw plate m...
