Drying is not in place. Dry wood processing is a complex process. The treatment is good and bad, and it has a great impact on the quality of wood products. Generally high-quality wood products are dried naturally for a long time, and then artificially dehumidified and dried. Different kinds of wood drying processes are not the same. If there are no advanced equipment, large venues and skilled operating techniques, even after drying, the above quality problems will eventually arise.
Wood products are eroded by water. Dried wood products, if incompletely closed, will swell when eroded by water, so wood products should not be exposed to the air for too long before being painted. When laying floors, pay attention to the bottom moisture treatment.
It is a white inorganic pigment with non-toxic, best opacity, best whiteness and brightness, and is considered to be the best white pigment in the world today. Titanium white has strong adhesion, is not easy to change chemically, and is always white. Widely used in coatings, plastics, papermaking, printing inks, chemical fiber, rubber, cosmetics and other industries. It has a high melting point, and is also used to make refractory glass, glaze, enamel, clay, high temperature resistant laboratory utensils, etc.
Anatase titanium dioxide belongs to pigment grade titanium dioxide, which has the characteristics of strong hiding power, high coloring power, and good weather resistance. Mainly used in industrial sectors such as rubber, plastics, papermaking, printing inks, coatings and chemical fibers.
The use of anatase titanium dioxide mainly has the following aspects: Titanium dioxide for papermaking generally uses anatase titanium dioxide without surface treatment, which can play the role of fluorescence and whitening, and increase the whiteness of paper. The titanium dioxide used in the ink industry has rutile type and anatase type. It is an indispensable white pigment in advanced inks. The titanium dioxide used in the textile and chemical fiber industries is mainly used as a matting agent. Since the anatase type is softer than the gold red type, the anatase type is generally used. Titanium dioxide is not only used as a coloring agent in the rubber industry, but also has reinforcing, anti-aging, and filling functions, and is generally based on anatase.
