Injection of Thermoplastic Polyurethane to Fix Diamond Beads on Wire Saws

摘要：

An investigation was reported of the injection of thermoplastic polyurethane (TPU) to fix diamond beads on wire saws. Effects of injection material hardness, injection temperature and dwell pressure on the mechanical properties of three types of TPU plastics were studied and the results showed that with the increase of material hardness, both the 100％ Modulus and the tensile strength of TPU were improved, but the rupture extensibility reduced. With the increase of injection temperature, the tensile strength increased but the rupture elongation decreased. To every type of TPU, a minimum injection temperature can be found for an ideal density of TPU.
