MECHANICAL
WORKING
It
is advised that protective plastic foil stays as long
as possible on the sheet during
the working and thus reducing the possibility of injuries
on the surface of the acrylic
glass. As mentoined earlier good results can be achieved
by mechanical working of
the Aglas plates. Hacksaws and circular saws can be
used for sawing. If we use
hacksaw with light metal blade and approximately 5
teeth on centimeter appropriate
speed would be 1500m/min.Circular saws demand circumferencial
speed of at least
3000m/min. During sawing plates must be firmly fixed
to avoid vibrations. The blade
must be cooled by air and water, if we are to obtain
nice and smooth cut. Thin plates
can be broken off along the cut that was previously
done by appropriate knife.
Milling: Various milling machines with milling-saws
of metal with 10000 to 20000
revolutions a minute. For drilling various drills can
be used. Twist blades with the
angle of the tip at 90 degrees can be very efficient
at 15000 revolutions a minute. Polishing: Good results
are achieved by the use of lacquers or polishing means
recommended by Akripol. Edges are polished well by
acetylene burner.
MODELLING
After
heated to 140 – 170 C Aglas becomes soft and can be
modelled and shaped.
Heating can take place in furnaces with the circulation
of hot air or IR heater.
When modelling all usual methods can be used: free
blowing, vacuuming, pressing, etc.
Aglas can be well modelled on a manual press the same
as on an automatic
vacuumforming machine. First heating usually shrinks
Aglas for approximately 2 %.
GLUING
For quality gluing of Aglas with itself
or with PVC, ABD, PC or wood two-component
acrylic glue Novopop is recommended. This glue is produced
by Akripol solely for this
purpose. Junction is transparent. Chemical structure
of hardened glue is quite similar to
Aglas. Firm and nice junction is conditioned by clean
and dry surface of the parts that
are to be glued. Gluing with cyanoacrylic glues, bands
and glues based on caoutchuk.
CARE
Although Aglas has excellent surface
firmness, it is susceptible to scratching. Aglas is
because of this cleaned only with water and liquid
detergents.When cleaning we can
wipe the product with rag saturated with liquid antistatic
to prevent accumulation of dust.
Alcohol can be used for cleaning. Acetone, nitro diluters
or chlorine carbohydrate must
not be used. Minor surface damage (scratches, cigarette
burns) are whetted off and
polished. For the repairs of bigger damage on bathroom
elements made od Aglas
Akripol produces two-component acrylic reparative bitumen
in standard sanitary shades.
