The elastic modelling quantity of steel is 200 times of left and right of high density polyethylene (HDPE) elastic modelling quantity normally, because the booster action of steel wire mesh frame makes rigidity, resistance to impact and the dimensional stability of steel wire mesh frame plastic composite plate 100, are better than any pure plastic plate.Simultaneously because net-shaped steel skeleton itself is again a kind of flexible structure, thereby make composite plate 100 that certain flexibility also be arranged in the axial direction.This composite plate 100 has had just, the characteristics of gentle combination, and is functional aspect loading and unloading, transportation, the adaptability of installing and reliability of operation, is convenient to loading and unloading, transportation, practicality and good reliability are installed.
Because the wire coefficient of expansion is 10.6～12.2 * 10
-6(1/ ℃), steel wire mesh frame plastic composite plate 100 are under the constraint of net-shaped steel skeleton, and the thermal expansivity of composite wood is improved greatly, lower than any plastic plate commonly used.By test, steel wire frame plastic composite plate 100 linear expansion coefficients are 35.4～35.9 * 10
-6(1/ ℃), be only 3～3.4 times of ordinary carbon steel material, greatly is better than the linear expansion coefficient 170 * 10 of pure plastic plate
-6(1/ ℃).Therefore this composite plate 100 has advantages of that thermal coefficient of expansion is little.
There are not the problem of brittle fracture in steel wire, especially mild steel wire, and steel wire makes the distortion of plastics and stress all can not reach the critical point that makes its generation rapid crack propagation.Therefore steel wire mesh frame plastic composite plate 100 can be avoided rapid crack propagation well.
In addition, this composite plate 100 can be adjusted by changing steel wire diameter, net spacing, plastic layer and plastics kind structure and the performance of composite plate 100, to meet different withstand voltage, heatproofs, requirement for anticorrosion.Therefore this composite plate 100 has structural behaviour advantage flexibly easy to adjust.
