Dispersant is a commonly used auxiliary agent in toner, which helps to wet the pigment, reduce the particle size of the pigment, and increase the affinity between the resin and the pigment, thereby improving the compatibility between the pigment and the carrier resin, and improving the dispersion...
The production process requirements of color masterbatch are very strict, and the wet process is generally used. The color masterbatch is ground and phase-inverted by water, and a series of tests should be carried out while the pigment is being ground, such as the determination of the fineness, d...
When light acts on plastic products, part of the light is reflected from the surface of the product to produce luster, and the other part of the light is refracted and transmitted into the interior of the plastic. When encountering pigment particles, reflection, refraction and transmission occur ...

If these additives are added to the raw materials of the product, they need to be added to the resin raw materials in the same proportion in the color matching proofing, so as to avoid color difference in the s...
In the process of plasticizing plastic raw materials, one or more of the following situations often occur, such as the rheology of polymers and changes in physical and chemical properties, which are usually characterized by the following properties:
1. Fluidity: The fluidity of thermoplastics can...
The pigments used in the color masterbatch must pay attention to the matching relationship between the pigments, plastic raw materials and additives. The selection points are as follows:
(1) Pigments cannot react with resins and various additives, and have strong solvent resistance, low migration...
Color masterbatch (also known as color masterbatch) is an aggregate obtained by uniformly loading super-constant pigments or dyes into resins. It is composed of three components: pigments (or dyes), carriers and auxiliary agents. concentrate, so its tinting strength is higher than the pigment its...
The raw material of plastic is synthetic resin, which is extracted and synthesized from petroleum, natural gas or coal cracking. Oil, natural gas, etc. are decomposed into low-molecular organic compounds (such as ethylene, propylene, styrene, ethylene, vinyl alcohol, etc.), and the low-molecular ...
Disposable lunch boxes are one of the disposable tableware and have a wide range of usability. There are various types of disposable lunch boxes. In this issue, we mainly know the following:
