Disperse are essentially water-insoluble dyes, which are affine to non-hydrophilic fibers such as cellulose acetate. They have different names such as acetate dyeing materials, acetate dispersed dyes, dispersion dyes and dispersion dyes, the most common of which are currently Disperse.
The nature of Disperse?
Disperse are short-chain polymers that can bind to fillers and pigments on one side and polymers, resins, and so on on the other. This feature causes the powders to spread evenly inside the container. Disperse in acidic and alkaline environments retain their properties and are compatible with any water. They also brighten the color of the shed and have no effect on the transparency of the shed.
The dispersion stage is the most troublesome stage in the process of making paint, in terms of time and energy. This is due to the difference in surface tension of the liquid phase (resins and solvents) and the phase (pigments and fillers). The granulation process is actually the mixing and solidification of solids in a liquid. During this process, the agglomerates (particles the size of pigments and fillers in normal sales packages are not the size of the original, but are in the form of agglomerates) become particle dispersions that can even reach the original size. The particles become smaller.
In fact, in the process of dispersing, molecules with only one polar group adhere to the pigment surface and expand to the resin with their non-polar chains. If the molecules have more polar groups, they are arranged in such a way that the free polar groups form a hydrogen bond and thus form a physical structure with the pigments. Therefore, the effect of the dispersant is investigated by two factors: the absorption of its polar group to the pigment surface and the behavior of its non-polar chain around the particle.
At first glance, the performance of dispersants may seem simple, but they have important implications for viscosity, granulation, storage time, and other important materials. For example, the solubility of the dye and its dyeing speed may be altered by the application of dispersants.
Most dispersants are anionic, but some surfactants used, especially those that increase the solubility of the dye and their uniformity, are non-ionic. They can be used to disperse the colors of the player, bent and dispersed in the dyeing bath or to disperse all kinds of pigments in the printing paste. They can also be used in high filler systems such as primers and putties for industrial and marine coatings.
Disperse storage conditions?
This material can be stored in normal environmental conditions for a maximum of one year and its color and properties do not change. Optimal conditions for keeping this product are between 10 and 35 degrees Celsius, and it is recommended to prevent it from being below zero degrees Celsius and direct sunlight.
