Paint Ingredient Before producing anything, we need to know about the use of ingredients. Some of the ingredients used in paints are: Say no to plagiarism.

There are two main categories of raw and extender pigments. The main pigments provide whiteness and color and are the main source of hiding power. Titanium dioxide (TiO2) is a predominant white pigment, providing exceptional whiteness by diffusing light; provides whiteness and coverage in matte and gloss paints. Extenders are used to ensure correct particle spacing to avoid crowding and loss of coverage and provide a greater tendency for paints to chalk. In contrast, color pigments (organic or inorganic) provide color through the selective absorption of light. Color pigments are composed in liquid dispersions called dyes. In factories, color pigments are used as a dry powder and in the form of a liquid colorant to produce pre-packaged color paints. Commonly used extenders are clay, silica, silicate, calcium carbonate, talc and zinc oxide. Binder Provides adhesion, integrity and toughness to dried paints by binding the pigment together. The properties of the binding effect such as flow leveling and gloss development. Oil-based binders generally refer to both oil and alkyd coatings, and some coatings, especially exterior primers, are made with the combination of oil and alkyds to achieve the proper flexibility. The most commonly used binder is cold-pressed flaxseed oil, however it can be made with walnut oil, poppy seed oil, safflower oil, or other less popular oils. Support The liquid part of the paint (also known as Support) provides the desired texture and consistency. it is possible to apply the pigment and binder to the surface to be painted. For most oil-based and alkyd paints, the liquid component is thinner, and water is primarily used in latex paint. When we apply paint to any surface, the liquid part (generally thinner) evaporates and what remains on the wall is pigment and binder. Together they are called the solid part of the paint (pigment + binder = solid). While coating is a combination of liquid and solid.PAINT PRODUCTION Paint production includes the following stepsPreparationMixingSmallingColoringFiltrationPackagingPREPARATIONPaints are prepared with pigments and fillers, binders (oil or resins), solvents, plasticizers, dryers and other raw materials. In industries, paints are produced using water ring vacuum pumps to suck the raw material into a chemical reactor which can reduce manual labor. MIXING Now the raw material is put into a high speed dispersion kettle which mixes all the raw materials and forms a mixture and a semi-finished paint is obtained. GRINDING Now the semi-finished paint is put into the horizontal milling machine to grind the granule (semi-finished paint residue ) into smaller particles, for better stirring.COLORING Now, after the grinding process, put the semi-finished paint into the color mixing tank, add some pigment or other additives to create more color for the paint. If the paint needs to be thinned, it can be finished in this tank.FILTERINGAfter all this mixing process,..
