Abstract

Nowadays, the filtration process is increasingly used in various areas such as water purification, food industries, air dust filtration systems and other separation applications. In this work, HDPE microporous filters were fabricated under different pressures and processing durations using sintering process and then characterized by different techniques. It was expected that the microstructure and mechanical properties of the filters could be controlled by changing the fabrication parameters such as temperature, pressure, processing time and also by changing the properties of resin such as powder shape, particle size and rheological properties. In the first step, using the DSC, MFI, rheological and optical microscopy tests, a most suitable polymer powder was chosen in sintering process. The sintering temperature was fixed in the vicinity of melting temperature of the HDPE powder, based on DSC result. In order to evaluate the mechanical properties and porosity of the samples, the results obtained from the shear punch test, acetone drop permeability, gas permeability, transition optical microscopy and SEM were used, and then the effect of pressure and processing time parameters on the characteristics of the product was studied. Finally, it was concluded that it was possible to make microporous filters with suitable mechanical properties, using sintering process at controlled pressure and temperature conditions. It was observed that, by increasing the time and pressure, on the one hand the mechanical properties of the products increased, and on the other hand, their porosity and the gas permeability of the vents decreased.
