Manufacturing Of Paint

Ingredients of paint

We must be aware of the ingredients used in any product before we manufacture it. Paints contain:

Colors made from dyes or other substances that are used for painting or other art forms

Binders or Vehicles

Carrier

COLORS

Pigments, which are finely ground powders, are used in paints for color and to hide. Primers and extenders are the primary pigment categories. Prime pigments give color, whiteness and concealing capability. Titanium Dioxide (TiO2) a white pigment with a high concentration, provides whiteness as it scatters the light. It is also used to hide in glossy and flat paints. Extenders help to keep paints from chalking by ensuring proper particle spacing. Color pigments (organic or inorganic), on the other hand, provide color through selective absorption. Color pigments, also known as colorants, are liquid dispersions of pigments. Color pigments can be used in factories as dry powder or liquid colorant to create pre-packaged color paint. Clay, silica and silicate are commonly used extenders.

The pigments are bound together, which gives the paints adhesion and strength. Binders can have a positive impact on properties such as gloss and flow development. Oil-based binder refers to both alkyd and oil coatings. Certain coatings such as primers and exterior coatings are made by combining both oils and alkyds to achieve the desired flexibility. Binders made of cold pressed oils are the most popular. Other oils can be used, such as poppy seed, walnut, safflower, and safflower.

Carrier

The liquid paint component (also known as Carrier) provides desired consistency, and allows the application of pigments and binders to the surface that is being painted. Latex paint is mostly made up of water and paint thinner. The liquid component (generally the thinner) evaporates when we paint a surface. What remains on the wall are the pigment and binder. They are referred to as the solid part of the paint. (Pigment + Binder = Solid). The coating is both liquid and a solid.

The steps involved in manufacturing paint are:

Getting ready

Blending

Shredding

Adding color

Sorting through

Loading up items for transportation

GETTING READY

Paints can be prepared from pigments and fillers as well as binders (oil, resins), plasticizers or driers. In Industries paints can be manufactured using vacuum pumps with water rings to draw the raw material through a chemical reaction, which reduces manual labor.

BLENDING

It is then put in a high-speed mixing kettle that will mix the raw ingredients and create a mixture.

GRIND

Original: SLAMMING

Paraphrased: BANGING

The horizontal sandmiller is used to reduce the size of the granules (residues from the semi-finished painting) for better mixing.

HUEING

The semi-finished paint can be added to the color mixing tank after the grinding. You can add pigment or additives in order to get a different color. The tank is used to dilution the paint.

SCREENING

Filtering the paint after mixing, grinding and coloring is necessary to remove any impurities.

Putting items in containers for transport

The machine will automatically pack the paint in boxes, barrels etc. after it has been filtered.
