Coating: Any liquid or fluidized compound or gum compound that may cover the surface of the material with a thin layer after solidification. It is defined as a mixture of insoluble substances suspended in a liquid oily medium, or suspended in an aqueous emulsion, and the liquid medium consists of a group of organic or inorganic substances, and it is exposed to air through polymerization reactions, oxidation or drying of a coherent layer (called the coating, with a surface adhesion strength) Coated.
A Brief History of Paints: From about 2000 BC, the Chinese discovered transparent lacquer using a milky gum (liquid from plant pots) from the lacquer tree as an interconnect, as the paints were known from about 1500 BC when the ancient Egyptians developed the science of coloring as they were They are then composed of animal fats, colored mineral materials, and black carbon. Since about 1000 BC, the Egyptians discovered varnishes from natural resins and beeswax. In the sixteenth century, the paint industry moved from China to Europe and later developed using vegetable oils. Tree resins as bonding materials and remain Plant products most commonly used as raw materials for the industry and with the beginning of the nineteenth-century paints are widely industry has developed rapidly due to the use of a lot of petrochemical compounds and intermediate and final thread as materials of up to 80%, such as cellulose nitrate.
Any paint consists of several basic components:
1- Binders: It is the main liquid that is responsible for carrying all other components of the paint, and the binder determines the type of paint, whether it is water, oily, cellulose or alcoholic, and the value of the paint depends on the value of the bond, and also stops Its quality is on the quality of the material and its ability to solve different components
.2- The basic rules: What is meant is the powder forming powder, which, together with the carrier, is the main consistency of the paint.
3- Colored oxides: which give the paint the required color. These oxides may be one, two or more colors, provided that homogeneity does not occur and chemical reactions affecting the paint are not occurring.
4- Auxiliary additives: They are improvers, stabilizers, and dryers, and they are in fact of paramount importance in the manufacture of paints, and of its types: • Materials to prevent sedimentation. • Materials to prevent crust formation. Dried materials. • materials to increase liquidity and operational (diluents). Glossy materials. • Matte gloss material. • Materials to increase flexibility. • fixing materials for paints. • hardened materials. • Water-resistant materials. • materials to increase heat resistance. • Materials that are resistant to bacteria and parasites. • Material to increase the resistance to corrosion of tin containers.
Paints Production Line:
paints go through several stages of the industry, namely:
1- Grinding stage: In this stage, the pigment powders are ground with a number of liquid materials and then kneaded to form the paint material.
2- Screening stage: The dough made from dye powders and some other materials is screened at this stage.
3- Grading stage: In it, the colors of the paints are adjusted according to need, and more than one color can be produced.
4- The Mitigation and Upgrading Phase: At this stage, the paint material is diluted by adding certain types of solvents to it until it reaches the required density, and this is done after reaching the required color tones with which the paints are then filled.
Paints production line parts:
Oil painting grinding machine.
Kneading mixer for materials with high viscosity.
Laboratory mixer for experiments.
The investor in the paint production line is required:
The investor in this project must study the aspects of the project well, including the market requirements and the different types of paints that are increasingly in demand and work to produce them, as well as study competitors in the field and take advantage of this study to the fullest extent and know the total costs of the project and compare them to the profits that can be achieved to ensure continuity The project in the long run.
