Research on lubrication systems for CPVC processing
The properties of several commonly used lubricants in CPVC processing,including brown coal wax(OP wax,E wax),PE wax,and OPE wax,were introduced.Under the set test con-ditions(test temperature of 185℃,engine speed of 40 r/min,test time of 10 min),the comparative test was conducted on the types and amounts of lubricants by using a torque rheometer while keeping oth-er formulations unchanged.
