Calcium silicate formation using of Nano-silica and wood flour calcareous-treated and investigating of properties of the wood plastic composite obtained from it
This study with aim of evaluation the Nano-silica and wood flour calcareous-treated and evaluation of properties of the wood plastic Nano composite obtained from it performed. For this purpose beginning, wood flour was treated by calcium hydroxide and then with weight ratio of 60 to 40 by Polypropyl...

This study with aim of evaluation the Nano-silica and wood flour calcareous-treated and evaluation of properties of the wood plastic Nano composite obtained from it performed. For this purpose beginning, wood flour was treated by calcium hydroxide and then with weight ratio of 60 to 40 by Polypropylene with 4 per hundred compound (phc) MAPP compatibilizer in extruder machine were mixed. Beside, Nano silica with weight ratio of 0, 1, 3 and 5 phc was used. Wood plastic Nano composites were fabricated by injection molding technique. Fourier transform infrared spectroscopy was used from wood flour changes after chemical treatment and for morphological study of Nano composites from scanning electron microscopy and X-ray diffraction were used.
