Everyone is familiar with pigments, because the use of pigments, the colors of things in life are not single, but more diversified. Pigments are not only able to color clothing, but also can be applied to any object, as you can see. So why does pigment achieve a good coloring effect? We all know that the general quality of clothes, wash up basically no fading, and in addition to the clothes, coloring items, generally will not fade, so why paint and other dogs remain on the items? For small series of questions do not know whether we have the same question, the answer to these questions are in the performance of pigments, only pigments to achieve the corresponding performance, in order to achieve the above effect. Next please follow small make up together to understand the performance requirements of inorganic pigments.

1. Good dispersion. The relative density of inorganic pigments is relatively high, generally 3.5~5.0. With high density and small specific surface area, inorganic pigments are easy to disperse in plastics. Due to the relatively low coloring power of inorganic pigments, when the concentration of inorganic pigments is large, the colors are very bright.

2. Good covering power. The so-called covering power is the ability of pigment to be applied to the coloring matter to make it opaque. The covering power of pigment varies with the size of the particle. The relative density and particle size of inorganic pigments are large, so most inorganic pigments have good hiding power.

3. Excellent weather resistance and light resistance. Pigment on plastic weather resistance, light resistance, directly affect its use value, generally speaking, inorganic pigments through the action of sunlight and atmosphere will lead to dark, dark, and will not fade. Generally speaking, inorganic pigments are much more resistant to weather and light than organic pigments.

Above is the requirement of the performance of inorganic pigments, do not know what you have to understand inorganic pigments, if you do not know the difference between inorganic pigments and general pigments, you can understand in the search engine above, and then look at the small article understanding will be more convenient. Organic pigments are still widely used in modern times, and factories are more inclined to use inorganic pigments, because on the whole, inorganic pigments have much better performance than general pigments, which is also the reason for the development of inorganic pigments in recent years.
