Scientific Investigation Into the Manufacture of Paint

Scientific Investigation Into The Manufacture Of paint

Introduction: PPG Industries is a leader in its markets; is a streamlined, efficient manufacturer; and operates on the leading edge of new technologies and solutions. In this assignment I will be comparing the process of paint with the industry and in the laboratory.

Process of paint

In the industry
Making paint involves mixing the pigment with resin, solvents, and other additives to form a paste. This is normally done as the first step.

In industrial used paint it usually then routed into a sand mill. Next it is placed in to a large cylinder where it grind the pigment particles, this process makes it smaller so and dispersing them through the mixture.

Paste – In this process the pigment manufactures sends the bags of the fine grain pigments to paint plants. Next the pigment is premixed with resin. Finally one or more solvent and additives is added to form a paste.

Dispersing the pigment – the paints is routed into a sand mill, the particles of sand or silica to grind the pigment particles. The sand mill makes them smaller. Dispersing them through the mixture. Finally the mixture is filtered so that the sand particles are removed.

Thining the paste – It this process the produced is thinned to produced the final product. The paste is transferred to the large kettles, which is agitated with the proper amount of solvent.

Canning the paint - In This process the final paint product is pumped into the caning room. Where a machine places the lids onto the filled cans, and other presses the lids to seal them. Next the bailometer is then cut and shaped the handles; this is before they are hooked into the holes in the cans.

In the laboratory
Separate the coloured solids from the water filtration
Set up Buchner funnel
Filter paper and Buchner flask
Connect the Buchner flask to the water pump and turn on the water supply.
Pour liquid into the Buchner funnel.
