With technological
advancements comes the discovery of new materials that will make the
manufacturing process easier and better on both the producer and consumer of
such products. Usually discovered after an extensive body of research into
viable alternatives, this is the form through which fluoroplastics came to be
in the market today.
As of the time of this
writing, these materials have been processed by hundreds of companies in China
only. This not only tells of its importance but the need to understand what
they are – and how they can be effectively processed for the best results too.
What are Fluoroplastics?
They are polymeric
substances which are formed by the replacement of some or all of the hydrogen
atoms they carry by those of fluorine. Depending on the process of manufacture
– which also determines how the chemical reaction will go – there can be
diverse kinds of fluoroplastics at the end of the production.
Of these, we have
- -
Polytetrafluoroethylene (PTFE)
- -
Perfluoro (FEP)
- -
Polyperfluoroalkoxy (PFA)
- -
Ethylene-trifluoroethylene
copolymer, and more.
They are also used in
different ways for the fabrication of different units. Thus, the need at hand
will determine which of these fluoroplastics will be made.
Manufacturing PTFE Rods
Of all the
fluoroplastics, PTFE happens to be one of the most important in the bunch. This
is not only because of the desirable properties of the materials but for the
fact that it takes special care and expertise to work this substance.
l The
desirable properties of PTFE rod are as
follows:
l The
applicable temperature range is extensive. It can keep soft for long-term use
in the temperature from - 200 ℃ to 260 ℃.
l High
chemical resistance. It is basically resistant to all chemicals except for some
fluorides and alkaline metal solutions.
l Excellent
flame retardancy. It is defined as flame retardant material in the air.
l Excellent
insulation characteristics (regardless of frequency and temperature).
l Low
water absorption. Having the smallest surface tension in a solid material, it
does not adhere to any substance.
It's because of these
excellent performances that it can be used in many fields, such as chemical
industry, machinery, electronic and electrical equipment, medical materials,
etc., mainly for long products and mechanical parts.
When manufacturing PTFE
rods for various purposes, such as:
- -
Chemical valves in fluid
handling industries
- -
Gasket material for high heat/
chemical applications
- -
Household items, e.g., frying
pans, etc.
It is vital that extra
care is taken to get the right product and desired features too.
Choosing the Right Equipment
When going for a PTFE
rod forming machine, care has to be taken to ensure it meets specific
standards.
The process has to be
conditioned in such a way that the material is formed in the mold, but doesn't
overlap with one another. This means that it has to be continually flowing
while still allowing for enough retention to take the shape of the mold.
At the same time, this
piece of equipment must be able to keep the PTFE at the desired temperature
during different stages of manufacturing lest the substance wastes or forms
wrongly.
These are all features
that come with the PTFE hydraulic press
machine from Dekuma which offers all of:
- - High repetitive progress
- - Active floating feature
- - Continuous pressure maintained in the same body
In addition, the
operation of a hydraulic press machine
for the PTFE rod of Dekuma is simple, and the pressure, stroke, and closing
height can be adjusted according to the requirements of the pressing process.
That way, the raw materials
are well taken care of, mixed optimally for the suitable chemical reactions to
occur, and the desired product is formed.
