استعمال المادة السيلانية لتحسين خصائص خشب المخلفات الزراعية البلاستيكي المستخدم في الهياكل الإنشائية

الملخص EN

This study is to take advantage of residues of agricultural fields Rice straw for the production of the plastic wood which was used in many applications because of the lack of good varieties of wood in Iraq environment, prepared composites of wood of polypropylene reinforced with fine Rice straw with size of particle >300µm and fraction of weight 40% and addition improving quality factors were preparal including the particles Silane coupling agents.

It became clear from this study that the treatment of Rice strawthe particles with Silane coupling agent at a ratio ranging between %2 -0.

1have indicated improvement of resistance to Flexural creep which led to bending resistance of the compounds material to Flexural creep strain% and this inturn led to an increase of the value of bending modulus Flexural Creep Modulus.

The increase in the proportion of material containing Silane decreased flexural creep strain energy and this due to the increase the bonding between the base material and material consolidation and that inturn also led to increase flexural strength(F.

S)compared with composite non treatment with Silane coupling agents.
