6. Using the Film Maker Accessory
The Atlas™ High Temperature Film Maker Accessory comprises of a
top (
4
) and lower (
5
) heated platen pressing assembly that each
contain a respective top (
13
) and lower (
14
) polished pressing surface.
A thin film of 29mm diameter and up to 0.5mm thickness can be
formed between these polished pressing surfaces by heating and
pressing of a polymeric or plastic type sample, but
a specific
preparation
of the sample is required.
The thickness of the film to be produced is controlled by a specific
sized spacer ring (
18
) used within and between the top (
13
) and lower
(
14
) polished pressing surfaces. The film thickness is also determined
from any procedural method that is adopted. Factors that influence a
method are the amount of sample introduced for pressing, the
temperature and the load applied whilst pressing.
The Aluminium Foil Discs
The 40mm diameter aluminium foil discs (
21
) supplied are an
important part of the film preparation procedure and are used to
“sandwich” a polymeric or plastic type sample between them, before
melting and pressing of the sample in the Film Maker Accessory of
parts. The spacer rings (
18
) have been specifically designed to
accommodate two aluminium foil disc (
21
) thicknesses. One foil disc
(
21
) will be in contact with the top polished pressing surface (
13
) and
the other in contact with the lower polished surface (
14
) to produce
films corresponding to a
nominal
thickness for the spacer ring size
selected.
The foil discs (
21
) can be used as supplied in the Film Maker
Accessory for any sample pressings, but they can also be formed into
the parts that constitute a “sample cup”. The use of an aluminium foil
sample cup can help to retain more easily any polymeric or plastic
samples that are in a bead or pellet form that can roll about and would
be difficult to contain centrally within the Film Maker Accessory of parts
for a correct pressing.
