Paints Industry: Raw materials & unit operations & Equipment & Manufacturing & Quality tests
AbdAl-Rhman MAgdy Abdullah YoussefIncreasing 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 .
