The hollow board has a flexible design structure

2017-11-04 num:

The top layer of the hollow board is made of wood veneer, which can basically eliminate the bamboo RIPS, but try to use melamine resin coated to increase wear resistance and surface hardness, whole sex and finish. Used for steel box corrugated board templates panel, should use modified melamine resin or alcohol soluble phenolic resin impregnated paper, impregnated paper number visible on the surface roughness and smoothness of the requirements.


Compared to the injection molding products, the hollow plate has the shockproof, flexible design structure, no need to open injection mold and other advantages. At the same time, the plate can be added by the control of flexible material antistatic, conductive masterbatch, etc., to produce which has the function of conductive, antistatic plastic hollow sheet plate, anti-static plate surface resistivity can be controlled between 106 ~ 1011. The resistivity of the conductive plate surface can be controlled between 103 and 105.
