Emulsions Emulsion may be defined as a mixture of two or more immiscible liquids. It is a solvent free binder used in the preparation of paints and coatings. Acrylic emulsions are produced by the process of polymerization, where monomers are dispersed in an aqueous phase to achieve greater uniformity and stability in these acrylic resin plants. Paints and coating based on the emulsion are high on performance and environment friendly.
Functions of Emulsion
- Excellent binding and hardness properties
- Adds elasticity to the paint
- Better sheen and gloss
- Excellent U.V. Resistance
The complete plant set up comes prewired, plumbed and with all product piping in place. Other optional features can be added to either module for additional production capability. Our highly mobile acrylic resin plants are built onto a rigid skid mounted steel frame, rust protected and painted. These modules are pre–run at our facility for final approval prior to shipping.
Acrylic Emulsion Production We can supply acrylic resin plants in various configuration for manufacturing acrylic emulsion with different formulations. The production of acrylic emulsion varies greatly from product to product in these resin manufacturing plants. Highlights of the production process for acrylic emulsions are as follows:
- Raw materials for the emulsion line include monomers, additives, activators, and catalysts in liquid or solid form. For stabilization, some monomers are pre-mixed with inhibitors.
- Catalysts are used for activating the monomers and initiating the desired reactions. Activators activate the catalysts, initiates the reaction, besides overcoming the effects of the inhibitors. Additives used in the mixture include detergents, dispersants, and pH-adjustment ingredients.
- Thereafter, the monomers are pumped from tanker trucks to monomer tanks for storage.
- From the storage tanks, monomers are pumped to holding/premixing tanks, additive, activator, and catalyst holding tanks where mixing occurs.
- The additives, activators, and catalysts can be directly added to the reactors without being mixed with monomers in their respective holding tanks.
- Then, the raw materials are mixed together in one of three temperature- and pressure-regulated reactors where polymers are formed. The desired chemical reactions are initiated by addition of catalysts and are regulated with additives or by pressure and temperature adjustment.
- The resulting acrylic emulsion polymers are pumped to blend tanks. Formalin is added in the blend as a preservative to control bacteria and mold growth and ammonia is added to for pH adjustment. Sodium hydroxide is another pH-adjustment chemical, added in the blend tanks.
- Ingredients such as emulsions, emulsifiers, surfactants, binders and thickeners are added to modify monomer viscosity, to stabilize the polymers and to hold the polymers in suspension.
