PVC polyvinyl chloride monomer structure simple formula is CH2 = CHCl. Carbon atoms arranged in a zigzag, nursery decoration company, all atoms are σ bond linked. All the carbon atoms are sp3 hybridization. The material properties are as follows: Density 1380 kg / m3 Young's modulus (E) 2900-3400 MPa tensile strength (σt) 50-80 MPaElongation @ break 20-40% Notch test 2-5 kJ / m2 glass transition temperature of 87 ℃ melting point of 212 ℃ Vicat B1 85 ℃ thermal conductivity (λ) 0.16 W / mK thermal expansion coefficient (α) 8 10-5 / K heat capacity (c) 0.9 kJ / (kg · K) Water absorption (ASTM) 0.04-0.4Price 0.5-1.25 € / kg Epoxy collection of light, there are two: one by hand trowel, and the other is carried out with an electric machine polished defects: 1. When polished and receive light to be stepped on already leveling the ground, nursery, so that the ground had already bumpy being trampled flat, after a good ground, nursery PVC floor, the surface obviously saw uneven brightness is not ideal 2. electrical machinery: electrical power, but not . Very soft to the concrete when the machines, and the received light is not ideal. Nursery decoration company | Zheng Yi Decoration Design Engineering (certified) | Kindergarten Ltd.
