The paint emulsion has an acrylic resin that acts as an adhesive on the surface. Because each color needs to be glued to stick to the surface. The acrylic resin in the paint sticks to the surface and keeps other materials in place after drying.
A dye contains pigments that give it a color and protect it from UV rays. It has a solvent that either dissolves part of it or improves the flow of the painting, and finally has a variety of additives such as emulsions. It is added. For example, in acrylic paints, acrylic resin (as an oil phase), along with the pigments that are already in it, are kept unstable in water. For this purpose, some special activating agents are used, which are called emulsifiers.
What is an emulsion?
Emulsion is a special type of mixture that consists of a combination of two liquids that are not normally mixed together. Therefore, in one emulsion, one liquid contains the dispersion of another liquid. Therefore, the process of mixing liquids without dissolving them is called emulsion. Common examples of emulsions include egg yolks, butter, and mayonnaise.
Most emulsions are unstable, and if the liquids they make are clear, they look colored because light can be scattered by suspended particles in the mixture. Also, some emulsions increase the viscosity of the environment and cause the globules to become unstable. Examples include acacia and travacant hydrochlorothiazide, glycerin, and carboxymethylcellulose polymer.
Types of Emulsion Categories?
Emulsion droplet sizes range from 10 nanometers to 100 micrometers. Therefore, these materials can be divided into two categories based on the size of their droplets, macromolecules (smaller than 100 nanometers) and micromolecules or nanomolecules (larger than 100 nanometers).
Also, based on the different poles of the dispersed phase and the continuous phase of the emulsions, they can be divided into two categories, direct and reverse. Direct emulsions are emulsions that have water as a continuous phase and oil as a dispersed phase. Unlike direct emulsions, reverse emulsions are emulsions that have oil as a continuous phase and water as a dispersed phase.
What is an emulsifier?
Emulsifier is a substance that stabilizes the emulsion. In fact, it increases the kinetic stability of a mixture. Surfactants or surfactants are one of the types of emulsifiers. Other examples of emulsifiers include lecithin, mustard, soy lecithin, sodium phosphate, diacetyl tartaric acid ester monoglyceride (DATEM), and sodium stearovil lactate.
Emulsions are a type of liquid colloid in a liquid in which tiny droplets of one liquid (for example, oil) are dispersed in another liquid (for water) without mixing with each other. This substance is widely used as a raw material in creams, cosmetic lotions, etc.
