Transcripts - Polyvinylchloride

  • 1. Javaid Iqbal Mohsin E12-343 Department of Metallurgy & Materials Engineering University of the Punjab,Lahore.
  • 2.  Is Made from salt (57 per cent) and oil/gas (43 per cent).  Commercial production: salt dissolved in water is chemically decomposed by passing an electric current produces chlorine caustic soda & hydrogen while oil/gas is refined and cracked to give ethylene.  When chlorine & ethylene are combined, the product is ethylene dichloride ; again transformed to give vinyl chloride, the basic building block of PVC.
  • 3.  chemical formula for vinyl chloride C2H3Cl.  Molecular weight=62.5g/mol  The half life of vinyl chloride in air is a few hours.  Slightly soluble in water & extremely flammable.
  • 4.  Weathering stability. PVC is resistant to aggressive environmental factors.  Versatility. PVC can be flexible or rigid & can last up to 100 years and even more.  Fire protection. PVC is a material resistant to ignition due to its chlorine content.  Recyclability. PVC is very recyclable, more so than many other plastics. .  Economical efficiency. PVC is the cheapest polymers providing products with the best quality- price ratio.
  • 5.  Medical applications i-e blood storage containers  Transport (dash board & door panels)  Building and construction  Packaging, pipes & wires coatings.  Art and design
  • 6.  This paper presents the production technique, characterization of polymer composites based on plasticized PVC and vulcanized nit rile rubber waste suitable for irrigations pipes for agricultural use.  Materials used to obtain required polymer are as follows:  PVC with a 64 K-wert value (moisture and volatile 0.2%  dioctyl phthalate(density 0.984 g/cm3, pH 7, 99.5% purity)  PVC stabilizer LGP 8008 (tribasic lead sulphate content 30– 60%, lead stearate diatomic content 10%–30%), (Zn content 11%, melting point 127°C).  vulcanized nit rile rubber powder obtained by buffing the rubberized metallic rolls.
  • 7.  have lower hardness  higher elongation at break  a better tensile strength  The selected polymer have good behavior under accelerated aging and for immersion in water also. The rapid expansion & consumption of PVC is due to:  Lower cost  Greater availability  Good mechanical properties
  • 8. Characteristics Compression molded sample Cl injected sample Elasticity % 7 8 Elongation at break% 300 300 Hardness °ShA 73 73 The results in above table show that the values for physical mechanical characteristics for compression molded samples, and injected samples are similar excepting: a slight decrease of elasticity a slight decrease of tensile strength and 100% modulus. The increase of rubber powder quantity leads to an increase of hardness, tear strength & decrease of elongation at break.
