Embodiment 1

[0005] Embodiment 1 Place the article to be processed in a sealed container. After putting it away, close the container, connect the container with a vacuum system, forcefully discharge the gas in the container to an absolute pressure of 350mmHg, and stop the decompression. Keep it like this for 2 hours. Nitrogen was then added to bring the vessel to atmospheric pressure. Repeat the operation 5 times. Sampling, according to the experimental method of GB18580-2001 standard climate chamber method detection, formaldehyde content 0.01mg / m 3 . Benzene and toluene were not detected.

Embodiment 2

[0006] Embodiment 2 Place the article to be processed in a sealed container. After putting it away, close the container, connect the container to a vacuum system, forcefully discharge the gas in the container to an absolute pressure of 5 mmHg, and stop the decompression. Stay in this state for 0.5 hours. Carbon dioxide gas is then added to bring the container to normal pressure. Repeat the operation 2 times. Sampling, according to the test method in the GB18580-2001 standard, the climate chamber method, the formaldehyde content is 0.04mg / m 3 . Benzene and toluene were not detected.

Embodiment 3

[0007] Embodiment 3 Place the article to be processed in a sealed container. After putting it away, close the container, connect the container to a vacuum system, and forcefully discharge the gas in the container to an absolute pressure of 20mmHg. Stop the decompression. Stay like this for 1 hour. Air is then added to bring the container to normal pressure. Repeat the operation 3 times. Sampling, according to the experimental method of GB18580-2001 standard climate chamber method detection, formaldehyde content 0.03mg / m 3 . Benzene and toluene were not detected.

Abstract

A method for removing the volatile pollutant from decorative board and its products includes such steps as putting the decorative board or its products in a pressure container, sealing, vacuumizing for 0.5-2 hr, filling N2 or CO2 or air, and repeating said steps 2-5 times.

Description

(1) Technical field [0001] The invention relates to a method for treating pollutants volatilized from interior decoration boards and products thereof. (2) Background technology [0002] A large number of woodworking boards and their products are used for interior decoration and decoration. After the project is completed, a large amount of harmful chemicals such as formaldehyde, benzene, and toluene accumulated in these materials will be released slowly, causing indoor environmental pollution. Seriously endanger people's health. Therefore, the state promulgated relevant standards: GB18580-2001 to control this kind of pollution legislation. The current treatment methods are: ① When preparing adhesives for boards and products, improve the formula and process to reduce the amount of harmful chemicals such as formaldehyde, benzene, and toluene. ② Use a sealing strip to seal the part that will release to reduce the release. ③ After the decoration is completed, the indoor enviro...
