Dispersant action:
1. Wetting effect
It can reduce the interfacial tension between the solid particles and the liquid, making it easier for the liquid to wet the surface of the solid particles, thus promoting the dispersion of the particles in the liquid.
2. Dispersion effect
By adsorption on the particle surface, a protective layer is formed to prevent aggregation and flocculation between particles. At the same time, the dispersant can also produce electrostatic repulsion or steric effect, so that the particles maintain a certain distance, so as to achieve a stable dispersion state.
3, stable effect
The stability of the dispersion system is maintained during storage and use to prevent the reaggregation of particles. The dispersion agent can improve the stability of the dispersion system by adjusting the charge distribution on the particle surface and increasing the repulsive force between particles.
Dispersant is widely used in coating, ink, ceramics, papermaking, pesticide, medicine and other fields, and plays an important role in improving product performance and quality.
OVERVIEW:
Dispersant 5040 high-efficiency dispersant is a polycarboxylate sodium salt type dispersant with good dispersibility and maximum pigment bearing capacity. It has excellent dispersibility to titanium dioxide, calcium carbonate and china clay, and the prepared coating has excellent performance. It is suitable for organic pigments, etc. Highly hydrophobic substances have stronger dispersing power. Application experiments show that Dispersant 5040 has the advantages of less useful amount, high efficiency, low viscosity, low grinding viscosity, wide dosage range, and good storage stability of the dispersion system
Advantages of dispersant 5040:
First, improve the dispersion effect
1. The solid particles can be evenly dispersed in the liquid to avoid agglomeration of particles, thereby improving the stability of the system. For example, in the paint, the dispersant can make the pigment evenly dispersed to ensure the color uniformity and hiding power of the paint.
2. Improve the fineness of the particles, make the particles finer, thereby improving the performance of the product. For example, in ink, fine pigment particles can improve the clarity and gloss of printing.
Second, enhance stability
1. Prevent particles from settling, delaminating or flocculating during storage and use. For example, in ceramic pastes, dispersants can ensure that the paste can maintain good fluidity and stability after a long time of storage.
2. Improve the heat resistance and weather resistance of the dispersion system and extend the service life of the product.
Third, optimize the processing performance
1. Reduce the viscosity of the system and make the processing smoother. For example, in the papermaking process, the dispersant can reduce the viscosity of the pulp and improve the operating efficiency of the paper machine.
2. Reduce the wear of processing equipment and reduce production costs. Because the particles are evenly dispersed, the friction and wear on the equipment are reduced.
Fourth, broaden the scope of application
1. It can make some difficult to disperse materials get good dispersion in a specific system, thus expanding the application range of these materials. Nanomaterials, for example, can be better used in various fields with the help of dispersants.
2. Adapt to different processing technology and conditions to meet the needs of different industries.
Usage and dosage:
Usually, the amount of dispersant is between 0.1% and 5% of the mass of the pigment or filler. In order to determine the best dosage, it can be gradually adjusted through experiments to observe the dispersion effect and system stability to find the most suitable dosage.
Areas where dispersants can be used:
Coating additives, electronic chemicals, leather additives, paper chemicals, plastic additives, rubber auxiliaries, textile auxiliaries, water treatment chemicals Wholesale advanced dispersants for paints, inks, pigments, cosmetics, detergents...Wholesale dispersant, polyurethane dispersant,
water based dispersant, water soluble dispersant,water-based dispersant, dishwasher dispersant, pigment polymer dispersant
How to use:
The amount of latex paint added to the interior wall is generally between 0.4 and 0.8%, and is generally 1.0 to 1.5% of the total amount of makeup filler.
The amount of latex paint added to the exterior wall is generally between 0.4 and 0.6%, and is generally 1.0 to 1.5% of the total amount of makeup filler.
Additives should be added in the early stage of the coating, and wetting agents such as WE405 and PE100 should be added in the formula to increase the dispersion wetting ability of the coating system.
Note:
Storage temperature 5~35ºC, cool and dry place, avoid long-term exposure to sunlight;
Product storage and transportation process to keep positive placement, this product water environmental protection, non-flammable, according to non-dangerous goods shipment;
Under appropriate storage conditions, the shelf life is 12 months, after the shelf life, the company's quality inspection department can be used.
The technical data mentioned above may vary according to the actual situation. Please consult our company for specific usage.
After testing, 0.5% to 1.0% of the total weight of the pigment filler is the active ingredient. It is important to determine the appropriate amount of additives in the coating formulation. If the amount of dispersant added is seriously insufficient, it can not be completely dispersed. However, the amount of grinding and pigment dispersion may not be enough to achieve good film gloss, hiding power and stability. However, excessive dispersant will increase the water sensitivity of dry paint film.
Customers can also use other types of thickeners according to the different requirements of production, storage, construction and film formation to achieve the rheological properties of the formula design. Since 5040 can be easily dissolved in water and added in any amount, there is no special requirement for the amount to be added. Paint, ink,

A dispersant or dispersant is a substance, usually a surfactant, added to a suspension of solid or liquid particles in a liquid (such as a colloid or emulsion) to improve the separation of particles and prevent them from settling or caking. [1]
Dispersants are widely used to stabilize a variety of industrial and artisanal products, such as paints, magnetic fluids, and salad dressings. Plasticizers or superplasticizers used to improve the workability of pastes such as concrete and clay are usually dispersants. This concept also overlaps greatly with that of detergents, which are used to bring oily contaminants into water suspensions, and emulsifiers, which are used to form uniform mixtures of immiscible solution bodies such as water and oil. Natural suspensions such as milk and latex contain substances that act as dispersants.

CARS
Automobile engine oil contains both detergent and dispersant. Metal-based cleaners prevent varnish-like deposits from accumulating on cylinder walls. They also neutralize acids. Dispersants keep pollutants in suspension.
Dispersants added to prevent the accumulation of gelatinous residues.
biodispersion
Dispersants are used to prevent the formation of biofilms or biofilms during industrial processes. It can also disperse bacterial mucus and improve the efficiency of fungicides.
Concrete and plaster
Dispersants are used as plasticizers or superplasticizers in concrete formulations to reduce water consumption while maintaining the desired slump (flow) characteristics. The lower water content makes the concrete stronger and more resistant to water penetration
Similarly, in the manufacture of wallboard, dispersants are used as plasticizers in the gypsum slurry to reduce water consumption. The less water you use, the less energy you need to dry the siding
cleanser
Dispersion is the main purpose of using detergents, where the liquid bath is water (detergents are also used as emulsifiers in some applications). Laundry detergent wraps dirt and grime in the debris and then naturally disperses.
Oil drilling
Dispersants in oil drilling help break up solids or liquids into fine particles or droplets into another medium. The term is often incorrectly applied to clay dispersants. Clay dispersants prevent the formation of "fisheye" balls. In order to disperse (emulsify) oil into water (or disperse water into oil), a surfactant selected according to the hydrophilic lipophilic balance (HLB) value can be used. For foam drilling fluids, synthetic detergents and soaps are used with polymers to disperse foam bubbles into the air or gas.
Oil spill
Main article: Oil dispersants
Dispersants can be used to dissipate oil slicks. They can transfer large amounts of specific types of oil from the sea surface into the water column, dispersing it quickly. They cause the slick to break down and form water-soluble micelles, which are quickly diluted. It then effectively diffuses into a larger body of water than the surface where the oil is dispersed. They can also delay the formation of persistent water-in-oil emulsions. However, laboratory experiments have shown that dispersants can increase the amount of toxic hydrocarbons in fish by up to 100 times and can kill the eggs.
Dispersants were used to clean up the Exxon Valdez spill, but were discontinued because wave action was not enough to mix the dispersants with the oil in the water. The dispersant Corexit 9500 was used to clean up the Deepwater Horizon oil spill. The dispersant Corexit 9527 was used to disperse the 1979 Gulf of Mexico oil slick (Ixtoc) over a thousand square miles.
Process industry
In the process industry, dispersants are added to the process liquid to maintain a fine dispersion of the liquid, thus preventing the formation of unnecessary deposits. Dispersants can function in both aqueous and non-aqueous media.
Surface coating
To provide the best performance, pigment particles must act independently of each other in the coating film and therefore must remain well dispersed throughout manufacturing, storage, application and film formation. Unfortunately, colloidal dispersions (such as pigment dispersions in liquid coatings) are inherently unstable, and they must be stabilized to prevent possible flocculation.
