The paper tube cutting machine is used to cut the long paper tube or paper core into small pieces, which will be used for the core of paper rope roll of paper rope making machine or paper roll of paper slitting machines. It is a very good machines used together with Paper Rope making machines and paper sltting machines or with other usages.

Various wood-based panels, etc., have different characteristics for the quality of the coating due to the form and processing of the constituent units.
Finishing can be carried out directly on the surface of the wood-based panel or after other forms of surface finishing.
Finished wood-based panels include transparent and opaque finishes as well as direct printing.
Plywood, veneer veneer, etc., due to the beautiful texture of the wood, it is usually used for transparent finishing, particleboard and medium density fiberboard, more opaque finishes, different substrates, and slightly different finishing processes.
Generally through the following process:
Surface clean → putty filling → drying → sanding → coloring → drying → shower coating, spraying, roller coating, brushing → drying → paint film modification.
All kinds of wood-based panels must be sanded in the later stage of production, but some dust, dust, abrasions or debris will remain on the surface of the artificial board during storage or transportation. If it is not cleaned, it will affect the later finishing and Exterior. Therefore, these dusts and the like can be removed by brushing, blowing, rubbing, and the like.
Putty filling: Although the substrate artificial board is sanded, there are still some holes or uneven areas on the surface, or the structure of the wood itself. For example, the diameter of the pipe of some kind of plywood is relatively large, although the texture is good, but the surface is rough. Therefore, the putty is filled and the oily putty is generally used. After the putty is applied, in order to obtain a smooth surface, it must be dried and sanded.
Coloring: Also known as primer coating, the wood-based panel substrate has a certain uniform or preferred color tone. It is mainly coated with a coloring agent of various dyes and coated on the surface of the artificial board.
Surface finishing: After the coloring is dried, the surface coating of the artificial board is carried out. Since it is carried out on a large plane, it is generally completed by three mechanical processing methods of shower coating, spray coating and roll coating.
Dry film: wood-based board coating, generally can be dried at room temperature, but the drying time is long. Therefore, the company uses forced drying method in mass production to give the film a certain thermal energy light energy, so that the drying speed of the coating film is accelerated.
Paint film grinding: After the surface coating is dried, in order to make the paint film smoother, it can be further polished and polished to obtain a high surface finish.
Wood-based panel surface finishing process
The surface of the wood-based panel can be decorated to make the surface of the wood-based panel beautiful, smooth, and strong. The surface of the artificial board is separated from the external environment by a paint film to protect the artificial board.
