Mechanical properties of recycled pp granule
recycled pp granule has excellent mechanical properties, including tensile strength, compression strength and hardness, outstanding rigidity and bending fatigue resistance. Movable hinges made of recycled pp granule can withstand more than 7×107 folding and bending without damage, and the impact strength is poor at low temperature. The tensile strength of PP is generally 21-39 mpa; Bending strength 42-56 mpa, compression strength 39-56 mpa, elongation at break 200% ~ 400%, notch impact strength 2.2-5 kJ/m2, low temperature notch impact strength 1-2 kJ/m2. Rockwell hardness R95~105.
The value and significance of recycling PP granules from the perspective of environmental protection
PP granules are a polypropylene material that can be used to make various plastic products. However, if discarded PP granules are discarded at will, they will cause environmental pollution. Recycling PP granules can reuse these wastes, reduce pollution, and protect the environment. Moreover, the manufacturing process of recycled PP granules can reduce energy and water consumption and production costs compared to the new PP particle manufacturing process.
Introduction to the characteristics of recycled pp granule
recycled pp granule is a polymer developed from propylene additive reaction. White waxy material, transparent and light in appearance. The chemical formula is (C3H6)n, the density is 0.89 ~ 0.91g/cm3, flammable, melting point 189℃, at 155℃ or so softening, the use temperature range is -30 ~ 140℃. Under 80℃ can resist the corrosion of acid, alkali, salt solution and a variety of organic solvents, can decompose under high temperature and oxidation.
About the mechanical properties of recycled pp granule
recycled pp granule has good mechanical properties, which can be directly manufactured or modified to manufacture parts of various mechanical equipment, such as industrial pipes, agricultural water pipes, motor fans, and capital construction templates. The modified polypropylene can be molded into bumpers, scratches, etc., greatly reducing the body weight to achieve the purpose of energy saving. recycled pp granule can also be applied to the preparation of various corrosion-resistant conveying pipes, storage tanks, valves, special-shaped fillers in packing towers, filter cloth, corrosion-resistant pumps and the lining of corrosion-resistant containers. In medicine, it can be used to make medical devices; recycled pp granule could also be developed and applied in energy industry through grafting, compounding and blending processes.
