Paints Industry: Raw materials & unit operations & Equipment & Manufacturing & Quality tests

Increasing student skills in the field work, and linking

theory with application, become the motivation to students to

join to factories and companies for achieving this target. One of

chemical process industries is the paints industry. Paints is a

main part of coatings, paints composed of five components

which are; resin (binder), solvent, filler, pigments, and

additives.

From the point of view of chemical engineering; paints

manufacturing, requires number of unit operation which are

mixing, milling, and filtration. These of operations done using

several industrial units which are; mixers, mills, and screen

filters.

Paints manufacturing done by adding binders, solvents,

and thickeners to provide a gel phase which its existence is a

mark for starting of adding fillers and pigment, through and

after manufacturing processes a samples send to laboratory to

done some tests, by which the manufacturer be sure from his

products quality, the main tests are density, viscosity, and

hiding power test, there several tests can be done also such as

wash-ability and impact test .
