Application of Leneta black and white check chart in Wooden ground floor paints color scheme test

With the development of science and technology, color matching technology has already realized accurate measurement and evaluation by computer, and it is also widely used in textile, clothing, printing, coating, papermaking, photography and other industries.


In the wood industry, according to the paper "Computer Color Matching Test of Wooden Floor Paint" published by several researchers from the School of Materials Science and Engineering of Nanjing Forestry University, Feng Lei, Li Shaocheng, Wang Baojin, Xia Chaoyan, and Zheng Min, the lack of application and unsuccessful. At present, wood paint color matching mainly relies on artificial color matching, and the difference in appearance between the finished product and the model is judged by the naked eye. Through a series of experiments, the author has made an in-depth study on the computer color matching of wood floor paint.

In the production of the color sample of the paint film cardboard, the author selected the American Leneta 2DX black and white covering power cardboard, stirred the prepared sample evenly, and then coated the film on the Leneta 2DX black and white cardboard with a coating stick. The thickness of the paint film is 100um (here the author should be referring to the wet film thickness, editor’s note), after the paint film is dry, compare the color matching effect according to the Colibri color matching software. Finally draw relevant conclusions.

It is worth mentioning that more experimenters often consider higher quality cardboard (such as Leneta cardboard) in order not to affect the preparation effect when choosing cardboard. The paper market is actually small, but the quality and price of domestic cardboard and imported cardboard are vastly different.

Taking Leneta cardboard as an example, it has great advantages over domestic cardboard in terms of surface smoothness and curling performance. Since Leneta cardboard does not add fluorescent whitening agent, it is not affected by the cardboard itself in terms of color comparison and colorimetry. In addition, its ink pattern has good structural integrity, which is also a great factor when testing paint adhesion on its surface. The advantages. And in terms of anti-penetration, since Leneta has good anti-penetration resistance to solvent and water solvent coatings, it will not cause cracks, cracks and pimples. The transparent varnish on the surface of Leneta cardboard is specially designed to make the coated liquid produce a good wetting effect without cracking and shrinkage caused by substrate problems. Compared with domestic products, this advantage is nothing more than that experimenters will fall in love with Leneta.
