Abstract
The method is as the follow. Two test blocks are lapped with their testing zones where one share 0.5g nylon powder is placed in between the testing zones and to place them in between the weights. To place the test piece into dry oven at temperature of 280+/-2 degree C for 35-40 min, to take it out for cooling down to room temperature and then the test piece is set on nonmetal material tensile strength tester to carry on binding powder determination. The average valve is finally taken as the test result.
