The Dispersing agent NNO mechanism of dispersant is a lot of people have a little understanding of it. In the production and operation of such a long time, there are indeed many people who consult about this matter. Today, it is sunny and sunny, and there is nothing wrong.
● Adsorption on the surface of solid particles, so that the surface of condensed solid particles is easy to wet.
● Polymer Dispersing agent NNO forms an adsorption layer on the surface of solid particles, increasing the charge on the surface of solid particles and increasing the reaction force between particles forming three-dimensional obstacles.
● Make the solid particle surface to form a double molecular layer structure, the polar end of the external dispersant and water have a strong affinity, increase the degree of solid particles wet by water. Solid particles away from electrostatic repulsion.
● Make the system uniform, increase suspension performance, no precipitation, so that the whole system has the same physical and chemical properties.
Water-soluble polymer as a dispersant can have many uses, what is his mechanism of action, this is a lot of people are more interested in, today we will follow the Dispersing agent NNO manufacturers together to study this topic!
The mechanism of action of water-soluble polymer as dispersant is:
(1) Their addition increases the viscosity of the slurry, equivalent to a thin layer of lubrication film attached to the surface of the fiber, play the role of water-soluble lubricant, so that the fiber sliding without entanglement;
(2) The increase of slurry viscosity greatly affects the freedom of fiber movement in water, so that the fibers do not contact each other, reduce the flocculation between fibers, and improve the formation and interweaving ability of fibers;
(3) The viscous force of the viscous medium on the fibers makes many fibers relax and become blunt before contacting each other when they stop stirring, thus forming fiber networks in the suspension which reduces the internal stress;
(4) The increase of the viscosity of suspension also increases the suspension of fiber in the medium and prolonging the settling time of fiber.
