DESIGN OF PAINT FACTORY MAKURDI
INTRODUCTION
1.1 BACKGROUND TO THE STUDY
Paint A factory or plant is a type of industrial site that typically consists of buildings and machinery, or more commonly, a complex of several buildings where workers process raw materials into paint. Factories arose as a result of the introduction of machinery during the industrial revolution, when the capital and space requirements for cottage industry and workshops became too great. Paint is a type of surface coating. It is a relatively opaque solid coating applied as a thin layer, with films typically formed through polymerization of polyunsaturated oil. Surface coatings are further subdivided into varnishes (clear coating), enamels (pigmented varnishes), lacquers (film formed solely by evaporation), printing inks, and polishes. Paints are generally low in thermal conductivity, electrically inert, and washable and cleanable. The various raw materials used in Pigments, vehicles, alkyd resins, surfactants, solvents (thinners), and coloring agents are all used in the production of paints. Paints are divided into two categories: resin-based paints (gloss finishes) and latex-based paints (Emulsion paints). The only difference between the two is the type of vehicle used and the cost. Resin-based paints, which dry to a lustrous or shinny finish, are used for exterior and interior surfaces. Emulsion (Latex) paint is an emulsion of two phases, one of which is water and the other is any other phase. Emulsion is traditionally defined as a suspension of one phase in another. Latex paints contain synthetic resin latex as the primary film-forming constituent, with or without other film-forming constituents added in an oil-water emulsion system. The continuous phase is made up of an Styrene – butadeux (SBR) copolymer, which was the original quality film former in emulsion paint, is a dispersed hydrophobic colloid in water that contains two different types of particles in suspension. As a film former, polyvinyl acetate (PVA), acrylic, and PVA acrylics copolymers have largely replaced SBR. Resins and latex are derived from these and used to create objects with a wide range of colors and textures found in household wares, building materials, electrical and electronic appliances, automobile and aeronautics, clothing, building structures, and so on. In short, it is difficult to imagine modern society without painting (colours). Paints are used as a finishing material for other materials. They are used to shield metals, wood, and plastered surfaces from the effects of weather, heat, moisture, and gases, among other things, thereby improving their appearance. Paints are used. Oil, water, cement, and bituminom paints are separated. There are also special paints used for specific purposes, such as heat resistance, fire resistance, chlorinated rubber paint, and so on.
