Optimization in polymer processing

>> Monday, 16 June 2008

An introduction to optimization in polymer processing based on extrusion. Described methods are universal and can be applied in other polymer processes. We start from definition than optimization methods, how we acquire input and output date and for the end input and output data in extrusion.

Every task to do we can present as an answer. Optimization would be looking for the best (extremum) in the possible answers with assumed criteria, defined target function (e.g. max. output, min. power consumption).

For small area statistical methods like regression analysis when full area is scanned is applied. For large area artificial intelligence methods have to be applied, e.g. neural networks, genetic algorithms and hybrid methods (connect more than one). Extrusion optimization is complex. There are many optimization criteria, they can be conflicting like max. output and min. power consumption and many input data (geometrical, process parameters).

We have two ways of collecting the output data for optimization. Experiments and simulations. First can not be applied in some situation like changes in screw design. Second does not have this limitation and it can be effective tool for acquiring the data.

The characteristic process for optimization is the constant development which you can see on the picture. Output data from experiment or simulation as optimized can be applied as input data for other research.

This is the introduction. In the near future DOE (design of experiments) will be described as a one of the optimization technique.
From one site we have simulations and experiments one and other cost, experiments we know why, and simulations (e.g. REX, Moldflow, Cadmould 3D-F, etc.) software availability, not cheap. On the other hand, optimization the same software availability (e.g. Statistica). The best would be both simulation and optimization integration. What is more know how. Does it limit anything? Investment which will return. This is the way of doing business. Would you like to know more please let me know in mail or in comment. I will try to add what is needed.


The world’s first polymer banknote

>> Tuesday, 3 June 2008

After plastic cards it is time to polymer banknote.

For hundreds of years, banknotes have been made from rag-based paper. Today, banknote issuers are faced with the challenge of increasingly sophisticated counterfeiting techniques and there are serious doubts that paper remains a viable material for secure banknotes.
CSIRO’s expertise in polymer and synthetic chemistry was used to develop a non-fibrous and non-porous plastic film, which the banknotes are printed on. This substrate gives high tear initiation resistance, good fold characteristics and a longer lifetime than paper.
The substrate and the specially-developed protective overcoat prevent the absorption of moisture, sweat and grime so that the polymer banknotes stay cleaner.
CSIRO has also developed a variety of overt and covert security features for use on polymer banknotes. These security features are produced from a combination of spectroscopic techniques, synthetic chemistry, nanotechnology, surface science microstructure manipulation and polymer chemistry.

Animal waste gets chance to become biodegradable plastic

>> Monday, 2 June 2008

For full story please visit University of Waikato web site. There will be no comment this time.

The new process, developed over two years by University of Waikato chemical engineer Dr Johan Verbeek and Masters student Lisa van den Berg, can turn animal protein waste like blood meal and feathers into a biodegradable plastic using industry-standard plastic extrusion and injection moulding machinery.

A process developed at the University of Waikato will allow animal waste to be turned into useful and biodegradable plastic.

"Proteins are polymers so we know they can be turned into plastics," Dr Verbeek said. "Plant proteins successfully been used to make bioplastics, but animal protein has always ended up gumming up the extruder. The process we've developed gets round that problem. People said it couldn't be done, but we did it!"

It's a source of plastic that doesn't rely on petroleum, so we also see it potentially being blended with conventional plastics to reduce the total petroleum load.

Plastic Fantastic - University of Waikato scientist Dr Johan Verbeek says the bioplastic created from animal protein waste can be used for plastic sheeting.


Plastpol 2008

>> Sunday, 1 June 2008

Just few words about 12th International Fair of Plastics Processing Plastpol which took place in Kielce, Poland 27-30 May, 2008. Sorry but there will be no sum up and statistics and even my own consideration the next time I will be prepared better. There are only two pictures of extrusion machines. The picture below presents machines from polish plastics machine manufacturer ZMCh Metalchem Gliwice one of it with high torque synchronous motor.
PS. Have you visited Plastpol? Please share your impressions.
