Carry weapon becomes tomorrow's peacetime instrument plastic will play a larger
role in peace as they do in war containing hundreds of plastic
another plastics were floating down the welcome other
others depending on plastics to get in there safely as parachute is made of nylon
plastic.
As for plastics in peace comfort serving
our needs
when we take to the open road we find them again in our car plastic plastic
plastic plastic.
That
when you look for them or under it. Perhaps they are in the sea.
Extracted from the air as nitrogen was a Muscle Shoals not part of the T.V.
Does the sun produce them as it does chlorophyll in plant of nature
or an invention of man. They are man made.
Why bother making them at all unless they improve on nature's handiwork the old
adage has it that necessity is the mother of invention this truer than in the feet.
Plastics.
Understanding of how this modern industry originated let us turn back the pages of
history to a natural product development
tasks. At
that time to make
but it was costly the slaughter of whole herds of elephants of the state
made it necessary to find an available substitute of the grand old packet
or by treating letters with nitric acid just as this chemist is doing
that for the resulting mixture
of shape
and pressure because
it was made up.
Called a new substance
made substitute for one of the earliest plastics made its way into the manufacture
of
frames for glass. But it had one serious defect.
It could burn it was
another Roosevelt was down on the White House
and flammable plastic was invented by Dr Leo Bickel in which he gave the name make
a life
is actually the same process but I'm different materials.
Dr Baker but together to come down to carbon hydrogen
and oxygen preserving fluid called formaldehyde.
Commonly called.
The product of this putting together sent us this is then heated the waste products
are driven off and the result is a resin which can be molded by heat
and pressure to any shape after it becomes a powdered resin.
Fillers are added which all of the properties of the basic compound.
Addition of asbestos may make it heat resistant just as insulating
electric iron handles fire helmet trade.
For example is a plastic material readily
perhaps the chemist desires an impact resistant resin to be used in industry where
derails are required something new that plastics.
Began to take a small part in the plastics are no longer a substitute
has better the dictionary not a plastic as any substance which
is capable of being molded modern plastics is actually more complicated
as the substances containing combine such
as petroleum
or another source material of plastics coal which was if you recall once vegetable
matter.
Made up of carbon hydrogen oxygen
but together with another molecule containing the same elements
or an arrangement and the reaction results in a new molecule which looks like the.
Yes. Now this summer.
Is like a game
but put them together
and you have an isolated disconnected
monomers a lot to help polymer it as justice is done to
a new entity a team. So our individual monomers by banding together.
With the cast acting as coach job isn't quite
that ish to undergo training.
Does the chemists want a flexible plastic five
dollars now plastic is ready to be processed it may be treated in many ways
it may be mold
it may be laminated.
Such a
great.
Production of three
hundred percent
can be made
out of China.
Not MY those now engaged in industry but by you. You yourself there are lies.
You want you want me Newmark your prosperity this world of the
molecule belongs to us it is yours to explore your new.
