Abstract:
The aluminum dross is industrial waste of casting process. Its them will now be reuse less. Form a study found that application materials are mixed in the polymer for add more properties. Especially mixed material type powder metal in the polymer resulting have a hardness properties higher. The researcher then had the idea to bring this playful dross utilization by apply mixed with polymer. Except to be the new composites with better property, it also helps reducing the environment problem form industrial wastes as well
This research is to study on experiment use aluminum dross reinforce in polypropylene by that crushing them by the process called ball mill to the particle size minor than 75 [mu]m, then take them as the filler in to the polymer by blending them with polypropylene. The process is called melt blending process, using internal mixer at content dross 1, 3, 5, 7 and 9% by weight, then is forming to testing specimen for testing mechanical properties, microstructure and thermal properties
Research is found aluminum dross can use reinforcing material for polypropylene by aluminum dross is to mixed in polypropylene revealed that the color of composites changes to grey color. The testing of mechanical properties is found that hardness, modulus of elasticity and resistance abrasion value became higher of polypropylene are higher becames of being mixed of aluminum dross but elongation is lower. The yield stress does not change. The testing of thermal properties is found that melting temperature does not change but crystallization became higher by recrystallization temperature in the range of 117 -122 degree Celsius effected in composites to have more rigid properties.
