Problems solved by technology

[0002] At present, there are many home decorations that exceed environmental protection standards. One of the reasons is the use of a large number of composite panels in interior decoration. Although the quality of panel products is getting higher and higher, there is still the release of toxic gases, such as panels, floors, and furniture. All three have the volatilization of formaldehyde, and superimpose to cause the pollution of indoor environment

Embodiment 1

[0023] Purchase four pieces of high-quality joinery boards from the same batch of wood-based boards from the same manufacturer, saw them into two equal halves, and then take samples to test the formaldehyde emission of these eight wood-based board samples. The test results show that the formaldehyde emission of the eight sample plates is basically the same at 1.2mg / L. One of the two samples from the same plate is randomly distributed in a ventilated place, and the other sample is processed by the method of the present invention. The processing method and process are as follows:

[0024] (1) Place the plate 17 of the sample in the airtight processing box 1 and code it layer by layer.

[0025] (2) Start the leveling pressure device 2, and lock the pressure when reaching the elastic critical value.

[0026] (3) Start the heating device 3, and the heated turbid gas overflows from the opened release valve 18, and is discharged through the pipeline purification device; after being...

Embodiment 2

[0042] The steps of this embodiment are the same as in Embodiment 1. The processing parameters were the same except that the temperature was changed to be locked at 60 °C.

[0043] After 72 hours, the sample processed by the method of the present invention and another sample processed by natural emission were used for comparative detection of formaldehyde emission, and the values ​​were 0.5 mg / L and 1.1 mg / L respectively.

Embodiment 3

[0045] The steps of this embodiment are the same as in Embodiment 1. The processing parameters were the same except that the vacuum processing time was doubled.

[0046] After 72 hours, the sample processed by the method of the present invention and another sample processed by natural emission were tested for formaldehyde emission, and the values ​​were 0.5 mg / L and 1.2 mg / L respectively.

Abstract

The invention discloses an anti-change environmental-friendly repurification treatment method for plates and an anti-change environmental-friendly repurification treatment apparatus and relates to the purification treatment of plates, furniture and the like in the technical field of decoration construction. The invention adopts the technical scheme for solving the problem that heating purification, humidification deliquescence purification, vacuum cupping purification, ozone purification, high pressure purification and sound wave purification of plates are achieved through a pressure device, a heating device, a vacuum air pump, a humidifying device, an ozone purification device, a high pressure air pump and a sound wave device, and the decoration pollution is controlled at the earliest stage.

Description

Technical field [0001] The invention relates to an anti-degeneration and environmental protection repurification treatment method and device for boards, floors, furniture, etc. used in home decoration, and is especially suitable for anti-degeneration and environmental protection repurification treatment of composite boards. Background technique [0002] At present, there are many home decorations that exceed environmental protection standards. One of the reasons is the use of a large number of composite panels in interior decoration. Although the quality of panel products is getting higher and higher, there is still the release of toxic gases, such as panels, floors, and furniture. All three have the volatilization of formaldehyde, and superposition causes the pollution of indoor environment. Individual consumers have to adopt day and night ventilation or install air purifiers, some use carbon adsorption, some use formaldehyde capture agents, and some use photocatalyst metho...
