Embodiment approach 1

[0013] This embodiment is a preferred embodiment. The hot pressing process of the bamboo container bottom plate, the hot pressing process is to place the slab in the hot pressing plate of the hot press, the hot pressing machine heats up the hot pressing plate and the hot pressing plate exerts pressure on the slab; The pressing plate is cooled, the temperature drops to 80°C, the pressure is released, the slab is taken out from the hot press, and the bottom plate of the bamboo container is obtained through trimming. Furthermore, the above-mentioned slab is placed in the hot-press plate when the temperature of the above-mentioned hot-press plate is 80°C. The container plate slab enters the plate when the temperature of the hot pressing plate is 60-82°C, and exits the plate when the temperature of the hot pressing plate is 60-82°C. Compared with the existing hot pressing process, the heat The hot platen of the press does not need to be lowered to normal temperature, but the plate...

Embodiment approach 2

[0018] The hot pressing process of the bamboo container bottom plate, the hot pressing process is to place the slab in the hot pressing plate of the hot press, the hot pressing machine heats up the hot pressing plate and the hot pressing plate exerts pressure on the slab; The pressing plate is cooled, the temperature drops to 70°C, the pressure is released, the slab is taken out from the hot press, and the bottom plate of the bamboo container is obtained through trimming. Furthermore, the above-mentioned slab is placed in the hot-pressing plate when the temperature of the above-mentioned hot-pressing plate is 70°C.

[0019] refer to figure 1 , figure 2 , a bamboo container bottom plate, comprising a main board body 1, the main board body is made by the above-mentioned hot pressing process; the upper surface of the main board body 1 is provided with a bamboo skin layer 11.

[0020] More specifically, the above-mentioned main board body 1 includes a curtain mat structure laye...

Embodiment approach 3

[0022] The hot pressing process of the bamboo container bottom plate, the hot pressing process is to place the slab in the hot pressing plate of the hot press, the hot pressing machine heats up the hot pressing plate and the hot pressing plate exerts pressure on the slab; The pressing plate is cooled, the temperature drops to 61° C., the pressure is released, the slab is taken out from the hot press, and the bottom plate of the bamboo container is obtained through trimming. Furthermore, the above-mentioned slab is placed in the hot-press plate when the temperature of the above-mentioned hot-press plate is 61°C.

Abstract

The invention discloses a bamboo container bottom board and a hot-pressing technology thereof. The hot-pressing technology comprises the following steps of: placing a board blank in a hot pressboard of a hot press, heating the hot pressboard by the hot press, and applying pressure on a board blank by the hot pressboard; and cooling the hot pressboard to the temperature of 60-82 DEG C by the hot press, releasing pressure, taking the board blank out from the hot press and trimming, so the bamboo container bottom board is obtained. By the technology, the technical biases against the prior art are overcome, the board blank is fed and taken out when the temperature of the hot pressboard is 60-82 DEG C; compared with the traditional hot-pressing technology, the hot pressboard of the hot press does not need to be cooled to the normal temperature when the board blank is taken out, and the board blank can be taken out at high temperature; when the board blank is fed again, the hot press can heat the hot pressboard through taking a higher temperature as a starting point, so the energy consumption of the hot press is effectively reduced, and the hot-pressing time to the board blank by the hot press is also effectively reduced; and furthermore, the production efficiency is effectively improved, and the production cost is also effectively lowered.

Description

technical field [0001] The invention relates to a container board and its hot-pressing process, in particular to a bamboo container bottom board and its hot-pressing process. Background technique [0002] In order to increase the flatness of the surface of the container bottom plate, a layer of material is usually added on the surface. The existing container bottom plate is usually provided with a paper layer on the surface of the board body. The preparation process of the container bottom plate includes a hot-pressing process. In the prior art, the completed slab is usually sent to the hot-pressing machine at 40-60°C. After the hot-pressing is completed, wait until the temperature of the slab drops to 40-60°C. When the pressure is released, the slab is taken out from the hot press to obtain the product. When the hot press is working, the temperature can reach up to 130-160°C. In this way, the hot pressing of the slab requires a large difference in temperature rise and fall...
