Problems solved by technology

[0002] At present, the method and equipment for producing wide-width (TT) plates are mainly extrusion and pressing methods, and screw extruder forming and auxiliary pressing machine are used for forming, but the disadvantage of screw extruder forming is that it produces wide width Boards are very difficult, such as the production of wood-plastic boards. At present, the widest production in China is generally 300mm, and the widest in the world can only be produced to 600mm; and in the production of wide boards, fibers and plastics, rubber, concrete (concrete), etc. The ratio of ingredients must be kept in a considerable proportion, for example, the fiber is below 70%, otherwise the fluidity of the mixture is too poor. Furthermore, due to the limited extrusion volume, large volume, plate thickness, and plate width are not suitable for large-scale industrialization. Producing wide format (TT) panels poses problems
The disadvantage of the pressing method is that it is not applicable to the production of thick, single-hole, double-hole, and porous wide (TT) plates in terms of process conditions, product shape, and dimensional deformation.

Embodiment 2-3

[0045] The production steps and molding equipment of Examples 2-3 are the same as those of Example 1, except that the fibers are poplar or rice husk powder, respectively.

Embodiment 4

[0046] Embodiment 4 is the production of rubber-plastic elastomer hollow board

[0047] Mix the fine rubber powder 80 mesh with ethylene-vinyl acetate, dioctyl phthalate, and sulfur in a high-speed mixer with a spacer according to the weight of Table 2, the modification temperature is 170 ° C, the time is 7 minutes, and the mixer speed is 3000 rev / min for modification. Then add the high-density polyethylene into the oil mixer according to the weight of Table 2 and plasticize it to a molten state, then add the modified rubber powder, the mixing temperature is 170 ° C, and the time is 7 minutes, so that the added materials are completely compatible. After cooling, the rubber-plastic elastomer is pulverized as a raw material for rubber-plastic sheet molding. Then in the wide-width sheet forming equipment, the heating oil temperature is 170°C, the pressure is 30Mpa, and the finished product speed is m / 9 minutes to form a 1000mm rubber-plastic elastomer hollow sheet, and then the ...

Embodiment 5

[0048] Embodiment 5 is fiber hollow board

[0049] The components and weights of the materials listed in Table 3 are fully mixed in the mixer, and the fiber hollow board is formed according to the process parameters listed in Table 3 in the wide-width sheet forming equipment, and the finished fiber hollow board is obtained after finishing and testing.

Description

Technical field: [0001] The invention relates to the field of non-metal wide-width sheet manufacturing, in particular to a method for industrially producing a wide-width (TT) sheet and its forming equipment. Background technique: [0002] At present, the methods and equipment for producing wide-width (TT) sheets are mainly produced by extrusion and pressing methods, using screw extruder molding and auxiliary press molding, but the disadvantage of screw extruder molding is the production of wide-width (TT) sheets. Plates are difficult, such as the production of wood-plastic panels. Currently, the widest production in China is up to 300mm, and the widest in the world can only be produced up to 600mm; and in the production of wide plates, fibers and plastics, rubber, concrete (concrete), etc. The ratio of ingredients must be kept in a considerable proportion, for example, the fiber is below 70%, otherwise the fluidity of the mixture will be too poor. Furthermore, due to the lim...
