Recycled Material

The aim of this research paper is to study the effect of particle size of recycled polymeric material to mechanical tensile properties. During grinding particles are formed which have a different size, shape and surface, from larger pieces to dust particles. During processing these particles melt at different rates depending on their size. For example they can cause material degradation or lack of melt homogeneity. Several recycled mixtures were prepared that had differed particle size after crushing. The recycled material is always the same as is the original material. The studied material was a Polycarbonate. Testing was performed using a tensile test. When comparing a virgin polycarbonate with recycled mixtures, the particle size of the recycled material affects some of the material parameters quite substantially, but it had no effect on some other properties.

Recycled Material

The aim of this research paper is to study the effect of particle size of recycled material on the micro harness. Valuation of recycled material effect takes place in several mixtures of materials. These mixtures differ in particle size, which are made during grinding of plastic waste, from large particles similar to the original material to dust particles. The recycled material is always the same as is the original material. Tested material is styrene acrylonitrile SAN. Testing is performed at ambient temperature of 23°C. After the first recycling there is a change of hardness; which decrease mostly in mixture with the smallest particles.

Reinforcing Filler

This research paper studies the influence of preparation method of recycled polymer material with glass fibers on the tensile properties of the final product. The recycled material was made from polypropylene, which originally contained 30 % of glass fibers. It was divided into fractions using size of the crushed particles. These fractions ranged from large particles, similar to the original material, to small dust particles. Measurements were performed at various temperatures. It was found that the mixture of dust particles showed a large decrease in measured properties. It is mainly due to shortening of the large glass fibers, so that it no longer fulfills its function as reinforcing filler. Conversely, mixture with larger particles did not show a significant decrease in properties compared to the original material.

This work aims to investigate the effect of recycled material and effect of particle size on the mechanical properties of the recycled material. Tested material is polyamide 6. Every manufacture of any plastic parts produces certain amount of waste, such as defective injects or cold runner system from injection molding technology. When size of this material is reduced, particles of different sizes are made. From large particles similar to the original granulate material, to dust particles. This size variation can cause problems during subsequent processing. These particles of different size have distinct melting rate. To determine behavior of recycled material at room temperature. Impact toughness and hardness tests are performed.

The aim of this research is to show influence of particle size of recycled polymeric material to mechanical tensile properties. During grinding, the particles with various sizes are formed, from larger pieces to dust particles. This size variation can cause problems during subsequent processing. These particles of different sizes have distinct melting rate. That can cause an inhomogeneity of a melt and diverse structure of a solidified polymer. Several recycled mixtures with varied particle size after crushing were prepared. Tested polymer was polyamide 6 and the tests were performed at ambient temperature.

Recycled Material

Every manufacture of any plastic parts produces some waste, such as defective injects or cold runner system from injection molding technology. This waste can be directly used several times. But when size of this material is reduced, particles of different sizes are made. From large particles similar to the original granulate material, to dust particles. This size variation can cause problems during subsequent processing. These particles of different size have distinct melting rate. That can cause an inhomogeneity of a melt and diverse structure of solidified polymer. This research paper studies the influence of the particle size of recycled polymeric material on the micro harness properties of semi-crystalline polyamide 6 at room temperature.

Recycled Material

The aim of this paper is to investigate the behavior of the recycled polymer containing the filler. The recycled polymer under investigation is polypropylene with a glass fiber filler. During grinding of plastic waste particles are formed which have a different size, shape and surface, from larger pieces to dust particles. Several recycled mixtures were made, all from original material. Samples with different particle size of recycled material were subsequently tested by mechanical testing. Included tests were Charpy impact test and Shore hardness test. Testing was conducted at different temperatures; ambient 23 °C and increased temperatures 60 ° and 100 °C. The results show a very large effect on Charpy properties and a lesser influence on the hardness of these mixtures. Mixture of smallest dust particles indicates larges change of measured properties.
