【Abstract】 The frictional properties between the continuous hot pressing machine board, steel strip, steel strip,and hot press plate, as well as steel strip and sealing strip, were investigated in this paper. Friction coefficient tests were conducted using a friction coefficient tester to determine the friction coefficients between wood materials and polyethylene plastic, steel strip, polytetrafluoroethylene, polyethylene engineering plastic, and steel strip. Factors influencing the friction coefficients of various friction pairs were analyzed with the aim of providing reference for the design and manufacturing of the continuous hot press for laminating artificial boards with pressure air-float veneers. The experimental results indicated that the static friction coefficient between polytetrafluoroethylene and steel at room temperature was 0.10, and the dynamic friction coefficient was 0.01. The static friction coefficient between polytetrafluoroethylene plate and steel plate decreased initially and then increased with the increasing of temperature, while the dynamic friction coefficient continued to increase. In the direction perpendicular to the wood grain, the static friction coefficient was maximum when moving along the polyethylene plastic film, with the value of 0.62. In the friction pair of artificial board and polyethylene plastic, the static friction coefficient of mediumdensity fiberboard ranged between 0.61 and 0.69, while that of particleboard ranged between 0.56 and 0.71.更多还原
