510-62 Special particle size distribution analyzer-air jet sieve for plastic materials PVDF-polyvinylidene fluoride
Special particle size distribution analyzer for plastic materials PVDF-polyvinylidene fluoride is air jet sieve. PVDF polyvinylidene fluoride, the appearance is translucent or white powder or particles. The molecular chain is arranged tightly. It has a strong hydrogen bond. The oxygen index is 46%. Non-ignitable. The crystallinity is 65%-78%. Density is 1.17~1.79g/cm3, melting point is 172℃.the thermal deformation temperature is 112~145℃. Long term use of temperature is —40~150℃. 1. PVDF has excellent chemical corrosion resistance, high temperature color change resistance and oxidation resistance. 2. PVDF has excellent wear resistance, flexibility, high tensile strength and impact resistance. 3. PVDF has excellent ultraviolet and high energy radiation resistance. 4. It has poor hydrophilicity. This property determines that only air jet sieve can be used to analyze the particle size accurately.
