ashless dispersant Surfactants

Dispersants are also surfactants. Species are anionic, cationic, nonionic, amphoteric and polymer. Anion is used most. The dispersant is suitable for powder or powder which is extremely susceptible to tidal agglomeration. It can effectively release loose and anti-caking effect without affecting the performance of the body. Can be widely used in various types of food and powder dispersants, feed, ammonium chloride and other chemical dispersants, paint dispersants, ceramic dispersants, phosphorus-free builders, kaolin dispersants, cement additives, paper dispersants, recycled water Disperse scale inhibitors and so on. The product has a good anti-deposition effect.

          The effect of the dispersant is to reduce the time and energy required to complete the dispersion process using a wetting and dispersing agent, to stabilize the dispersed pigment dispersion, to modify the surface properties of the pigment particles, and to adjust the movement of the pigment particles. The specific use of dispersants is reflected in the following aspects:

1. For all kinds of food and powder, dispersant has a good anti-crystallization effect, can maintain the quality of food and medicine in a very long time does not change, is a very good safe anti-agent.

2. This product is chemical fertilizer (especially ammonium chloride, ammonium bicarbonate) anti-caking agent, can make these easy to absorb moisture caking material to maintain a loose effect, to extend product quality and use of the cycle.

3. As a pigment dispersant, you can achieve this product and the interaction of pigment particles to achieve the dispersion of paint to ensure the uniformity of paint.

4. As a builder In the synthetic detergent, this product has the role of dispersion of dirt particles and calcium soap dirt, chelating the performance of multi-valent particles, and dirt particles have a strong adsorption force. To improve the decontamination of particle detergent, 5 times more than commonly used sodium tripolyphosphate, the dispersion of calcium soap capacity, 6 times greater than sodium tripolyphosphate. Has a good anti-deposition effect, acid resistance was significantly greater than sodium tripolyphosphate.

5. Cooling circulating water scale inhibitor can effectively prevent calcium carbonate, calcium carbonate scale, the dispersant can chelate calcium ions, so that the saturation concentration of calcium increased several times, calcium ion concentration is high, there can be scale precipitation , In the scale of particles on the surface, hinder the accumulation of large particles and the formation of precipitation, even if the formation of scale layer is also very loose, easy to wash away the water, so as to achieve anti-scaling, the purpose of scale. Dispersant is a surfactant that has both lipophilic and hydrophilic properties at the same time in the molecule. It is possible to uniformly disperse the solid particles of inorganic and organic pigments which are difficult to dissolve in the liquid, and also to prevent the settling and agglomeration of the solid particles and to form the medicament required to stabilize the suspension. Dispersants are generally divided into two major categories of inorganic dispersants and organic dispersants. The effect of the dispersant is to reduce the time and energy required to complete the dispersion process using a wetting and dispersing agent, to stabilize the dispersed pigment dispersion, to modify the surface properties of the pigment particles, and to adjust the movement of the pigment particles.

       Organic polymers have the disadvantage of poor heat resistance and dimensional stability. If the inorganic material or the inorganic filler is incorporated into the composite material, it can be overcome, but the performance of the material and the performance of the finished product Adverse effects. While the dispersant can improve these adverse effects. The dispersant has the best effect on the modification of calcium carbonate, barium sulfate and titanium dioxide, and has no effect on graphite.
