Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wood processing and surface treatment technology, and relates to floor surface treatment, and in particular to a teak wood flooring xenon lamp irradiation color-changing device and its usage method. Background Technology
[0002] Traditional solid wood flooring production relies on sun-drying to achieve color change, which has drawbacks such as a long processing time (usually over 30 days), weather-dependent limitations (work cannot be done on rainy days), uneven lighting leading to color differences, and direct sunlight causing flooring deformation and cracking. CN214778621U discloses a surface brightening irradiation device for SPC flooring production. A rotary motor drives a first rod to rotate, which in turn drives a conveyor belt, moving the SPC flooring along the belt to a suitable position. Then, a lead screw motor drives a second rod to move a moving plate, which in turn moves a fixed rod along a groove, adjusting the irradiation machine to a suitable height. This enhances the effectiveness of the surface brightening irradiation device for SPC flooring production and avoids the harmful effects of ultraviolet radiation on human health. CN221017150U discloses a surface brightening irradiation device for SPC flooring production. This device uses a progressive screw to drive the lifting plate up and down, while simultaneously rotating plastic toothed columns inside the toothed opening. This allows for adjustment of the UV lamp's position and angle. Two top plates slide relative to or opposite to each other on the periphery of a telescopic rod, enabling installation according to the width of the conveyor equipment. While the above-mentioned prior art improves upon the height or width adjustment of surface brightening irradiation devices for SPC flooring production, it is not suitable for the processing requirements of traditional solid wood flooring that requires natural air drying.
[0003] In traditional teak flooring production, sun-drying is mainly used in small quantities to achieve the surface color change effect. However, this method is unusable on cloudy or rainy days, and direct sunlight can cause the flooring to shrink and warp. CN101670603A describes a method of color-changing teak flooring by irradiating it with ultraviolet light of wavelengths 280-400 nanometers after surface soaking. However, this requires high light intensity, multiple cycles, and a complex process. CN102642225A discloses a method for treating teak color change. First, a special color-changing solution is used to wipe the teak surface to remove pigment deposits within the wood, eliminate black streaks and spots, and lighten the original color. After the teak surface is slightly dry, a photoinitiator is applied and left to stand for 20-40 minutes to improve the teak surface's light absorption capacity. Finally, the surface is placed under an irradiance of 250-765 W / m². 2Xenon lamp irradiation treatment with a wavelength of 300–800 nm and a standard blackboard temperature of 35–100℃ for 1–5 hours achieves a pale and uniform yellowish-white color. This technical approach, which involves chemical modification followed by xenon lamp irradiation, can easily cause uncontrollable changes to the color-developing structure that was originally damaged by reduction / oxidation, thus affecting the color adjustment effect. Summary of the Invention
[0004] In view of the problems of long natural drying cycle, poor uniformity, and easy deformation of flooring in the existing technology, the purpose of this utility model is to provide a xenon lamp irradiation color-changing device for teak flooring that is not affected by weather and can be continuously produced industrially. It significantly shortens the color-changing cycle, improves the uniformity of color changing, and effectively prevents the flooring from deforming and cracking during the color-changing process.
