Treatment method for removing formaldehydes in board

Abstract

The invention provides a treatment method for removing formaldehydes in a board, and the treatment method solves the technical problems such as too simple steps, needed manual operation and low treatment speed of an existing treatment process. The treatment method for removing formaldehydes in the board comprises the following steps of: a, preparing a formaldehyde remover which consists of the following components in parts by weight: 50-60 parts of a plant extracting solution, 6-10 parts of sodium bicarbonate, 1-4 parts of nano titanium dioxide, 6-9 parts of hydrogen peroxide, 2-6 parts of a nano antibacterial agent, 1-3 parts of a penetrating agent, 1-2 parts of a preservative, 2-4 parts of a surfactant and 30-40 parts of water; b, spraying the formaldehyde remover to the surface of the board by spraying equipment with spraying thickness of 0.8-1.2mm, standing for 4-6 hours, and irradiating for 1-3 hours through ultraviolet ray lamp; and c, drying the board in the step b by air-curing equipment for 20-40 minutes at an air-curing temperature of 40-60 DEG C. The treatment method has the advantage of high treatment efficiency.

Description

technical field [0001] The invention relates to a treatment method for removing formaldehyde in plates. Background technique [0002] With the continuous improvement of people's living standards, as well as the continuous strengthening of health awareness and environmental protection awareness, people are increasingly concerned about their indoor environment. People mostly use various new materials such as wood-based panels for interior decoration. However, while beautifying the living room, wood-based panel products such as plywood, particle board, density board, and fine-work board become the main source of indoor formaldehyde. Formaldehyde has an irritating effect on human skin and mucous membranes, and can easily cause edema, inflammation, and ulceration in the throat, eyes, and nasal cavity. Long-term exposure may even lead to serious lesions such as nasopharyngeal cancer. In addition, formaldehyde is more harmful to infants and pregnant women. Seriously, it can cause ...

Problems solved by technology

[0004] Although the treatment process disclosed in this patent can reduce the formaldehyde content inside the board, the steps of the treatment process are too simple, manual operation is required, and the processing speed is slow. Therefore, it is very important to design a treatment method for removing formaldehyde in the board. necessary
