  • 1. Guided By: Presented By: Prof. Gargi Mam Pratik Choudhary Yogesh Agrawal
  • 2. • Paint is one major segment of the surface coatings, which also includes varnishes, enamels, printing inks and polishes. • The paint industry produces a huge variety of products that protect, preserve, and also beautify the objects to which they are applied. • Typical products include architectural coatings (e.g. house paints), industrial coatings (e.g. automotive finishes, wood furniture and fixture finishes), and special purpose coatings (e.g. traffic paints, roof coatings). Introduction
  • 3. Solvents (Liquids) Pigments Additives Resins (Binder)
  • 4. • Titanium Dioxide (TiO2) • Provides excellent hiding power and whiteness. • Available as a solid (powder) or liquid (slurry). • Zinc Oxide • Controls mildew • Resists ultra-violet light • Resists yellowing • Titanium dioxide is the world's primary pigment for providing whiteness, brightness and opacity. Prime Pigments
  • 5. • Binds or glues ingredients (pigments and additives) of paint together. • Resin provides adhesion to the substrate. • Resin provides durability & resistance properties: • U-V resistance • Moisture resistance • Chemical resistance • Stain resistance • Fade resistance • Chalk resistance • Block resistance Resins
  • 6. • Fillers are a special type of pigment that serve to thicken the film, support its structure and simply increase the volume of the paint. • Fillers are usually comprised of cheap and inert materials, such as talc, lime, clay, etc.
  • 7. • The main purpose of the solvent is to adjust the viscosity of the paint. • Water is the main vehicle for water-based paints. • Solvent-based paints can have various combinations of solvents as the vehicle, including aliphatic, alcohols, etc. • These include organic solvents such as petroleum distillate, esters, glycol ethers, and the like.
  • 8. • Additives are mixed in very small amounts and yet give a very significant effect on the product. • Additives are used because:  Modify surface tension.  Improve flow properties.  Improve the finished appearance.  Improve pigment stability.  Control foaming.  Control skinning.
  • 9. 1. Raw material: Resin, pigment and additive agents are generally major components of paint. 2. Mixing: Resin, pigment and solvent are mixed to produce an even mill base. 3. Milling: Mill base produced at the pre-mixing process is sent to the disperser to finely disperse the pigment particles.
  • 10. 4. Blending: Resin, additive agents and so on are added to the mill base, the dispersion of which is completed. Also, the color phase is adjusted with color materials. 5. Filtering: Blended and toned paint is filtrated. 6. Packing: Filtrated paint is packed into a container.

  • 12.  GUI (Graphical User Interface) of paint manufacturing process has been created using Labview.  With the help of Labview whole plant can be virtually visualized.  Process can be controlled and monitored i.e level monitoring, valve indications, pump indications, etc.  Front panel & block diagram are easy to handle.
  • 13. It is concluded that with the help of labview and its various tool box different units of paint manufacturing process has been designed. With an additional monitoring and controlling the level of various tanks & controlling of mixer, valve & pump indications.
