Influence of Technological Parameters of Pressing and Ultrasonic Fluctuations on Adhesional Durability of Antifrictional Polymeric Compositions

摘要

The influence of technological parameters of pressing and ultrasonic fluctuations on adhesional durability of polymeric coverings is investigated in the paper. The investigation showed that the adhesional durability is changed in various parameters of pressing from 4 to 18.4 MPa, hardness HB from 74 to 188 MPa, destroying pressure on compression from 46 to 181 MPa, density from 1544 to 1694 Kg/M{sup}3. The optimum modes of pressing are determined: the time of endurance under pressure - 0.8 min/mm, pressure 54-75 MPa, temperature of pressforms - 438-463 K. Influence of ultrasonic fluctuations allowed to increase adhesional durability from 18 MPa to 25 - 30 MPa.
