High-voltage pulse electric field treatment device for accelerating releasing of formaldehyde in artificial wood board

Abstract

The invention discloses a high-voltage pulse electric field treatment device for accelerating releasing of formaldehyde in a nartificial wood board. The high-voltage pulse electric field treatment device comprises a strong pulse electric field treatment chamber. A high-voltage electrode used for generating a strong pulse electric field and a low-voltage electrode are arranged in the strong pulse electric field treatment chamber. A high-voltage pulse power source is used for supplying electricity to the high-voltage electrode, which generates the strong pulse electric field, in the strong pulse electric field treatment chamber. The output voltage of the high-voltage pulse power source is adjustable so that the strong pulse electric field with the adjustable electric field intensity ranging from 10 kV / cm to 100 kV / cm is formed between the high-voltage electrode and the low-voltage electrode. The to-be-treated board is placed between the high-voltage electrode and the low-voltage electrode. According to the high-voltage pulse electric field treatment device for accelerating releasing of the formaldehyde in the artificial wood board, releasing of the free formaldehyde in the artificial wood board can be accelerated within relatively-short time, accelerated decomposing and releasing of unstable groups in an adhesive are promoted, and therefore the content and the releasing amount of the formaldehyde of the board are reduced, and the environment-friendliness grade and additional value of the board are improved.

Description

technical field [0001] The invention relates to a high-voltage pulse electric field treatment device for artificial wood panels, in particular to a treatment device that utilizes a strong pulse electric field to accelerate the release of free formaldehyde in artificial wood panels, and belongs to the field of formaldehyde reduction for artificial wood panels. Background technique [0002] In the past 30 years, with the continuous improvement of my country's economic level, my country's interior decoration has become a trend. From large shopping malls to small street shops, from bungalows to exquisite apartments, various decorations are being carried out, and from large to large , Medium-sized cities are spreading to small towns and wealthy rural areas. In interior decoration, artificial wood panels based on plywood, particle board, density board, fiberboard, blockboard, sliced ​​board, and reinforced composite floor have been widely used, such as interior modeling, furniture ...

AI Technical Summary

Problems solved by technology

One is to adjust the formula to improve the adhesive, but the cost of formaldehyde-free glue is relatively high, and it cannot replace the market position of urea-formaldehyde resin glue; Manufacturing cost, and requires precise control, it is difficult to apply on a large scale; the third is to use post-processing methods, such as the use of vacuum negative pressure method to accelerate the release of formaldehyde, ammonia suction method to reduce the formaldehyde content in the plate, but the vacuum negative pressure method requires vacuum The equipment is not suitable for large-scale industrial applications, and the ammonia gas in the ammonia suction aldehyde method is likely to cause secondary pollution
