Few people understand or know anything about colloidal
chemistry. Colloidal Chemistry was evolved by David Graham, a British chemist, 50 years
ago, but only recently has it been realized even by scientists what an enormous influence
it is destined to have in medicine, agriculture, and industry. Colloidals are known as the
twilight zone of matter. These mineral elements are the smallest particles that matter can
be divided while still maintaining its individual characteristics. Colloids range in size
from 0.01 millionth's of an inch to 10 millionth's of an inch 0.01 microns to 10 microns).
The smaller colloids cannot be seen with the most powerful microscopes. Because of their
small size, they have an enormous surface area, which gives them special properties. One
teaspoon of colloids can have a total surface area of over 127 acres, and is composed of
billions of tiny electrically charged minerals. Colloidal and suspended PTFE particles are the core and provide the extraordinary performance of
Fluids are used as a "carrier" to present
the PTFE particles to the surface which bears the weight and friction or the
surface that will be exposed to hostile chemical or physical conditions. Fluids used for
lubrication have traditionally been natural, mineral petroleum derivatives; some commonly
found in motor oils and light machine oils to industrial bearing greases to lighter
"Vaselines". Recent introductions of "synthetic" lubricants have
become popular; one of the first being "Mobil 1" motor oil. A most favorable biodegrable water-rinsable multi-use solvent-degreaser is soybean oil methyl ester. POLYTETRAFLUOROETHYLENE (PTFE) has a relatively heavy molecular
weight and have an affinity or attraction for each other. Accordingly, the process of
introducing PTFE particles into fluids usually results with agglomeration of the
PTFE powder into a syrup-like, gluttonous, unusable mass. |
