Using Recycled Rubber Particles as Filler of Polymers

Abstract

One of a way of a material utilization of a rubber waste originated at a recyclation of tyres is its inclusion into polymeric materials. The paper describes chosen mechanical properties of an epoxy adhesive and polyurethane filled with the waste rubber. The waste rubber was gained as one of outputs of a recycling line of a firm Gumoeko, Ltd. The filler presence influences resultant mechanical properties and decreases a price of gained materials. Defining of mechanical properties enables to specify possible application areas.

Dynamics of a Moulding Cooling at Injection of Plastics

“…Amplitude, phase and transition characteristic of the action quantity and the control of the regulation circuit at use of the proportional regulator constructed on basis of the transfer ( 9) respectively (11) show that the circuit is stable a periodic. From the amplitude, phase and transition characteristic of the regulation circuit defect constructed on the basis of the transfer (10) it is seen that the defect in the regulation circuit is relatively fast lowered.…”

“…From the mentioned conclusions it is seen that the moulding cooling in the mould at injection of plastics with the proportional regulator introduces the regulation with relatively favourable regulation properties [9][10][11].…”

Differential Scanning Calorimetry as a Tool for Quality Testing of Plastics

“…DSC method is for evaluation quality of plastics, optimization of technological processes or for development of new composite systems used together with the other physical methods like is IR spectroscopy, thermogravimetry, rheological or mechanical tests of materials and so on [5][6][7]. Such connection of these physical and analytical methods makes possible to carry out complete analysis of material quality and to consider technological suitability of their processing [8][9][10].…”

Caracterización Del Material Compuesto De Resina Poliester Con Partículas De Caucho Reciclado Y Su Aplicabilidad en Carrocerias.

“…Además, a medida que aumenta el contenido de caucho reduce notablemente las resistencias del compuesto, y mientras el tamaño de la partícula sea menor, menor será su resistencia y módulo de elasticidad. (Valášek, Müller, & Ružbarský, 2014), en su estudio corroboraron la hipótesis de obras de otros autores, la presencia de partículas inorgánicas tiene un impacto negativo con respecto a las propiedades mecánicas del material, sin embargo, en las pruebas realizadas evidenciaron que mientras aumenta la concentración de partículas de caucho reciclado lleva a disminuir proporcionalmente valores de dureza, resistencia a la tracción y cizalladura, pero pese a los resultados obtenidos establecen que es necesario preferir el uso de materiales de desecho debido a que es un tipo de reciclaje rentable y respetuoso con el medio ambiente adecuado para aplicaciones donde no se requiere valores altos de resistencia.…”
