Both belong to template materials with low strength and rigidity, and low turnover rate, but the cost is relatively low.Because of different uses, it can not be compared: wood plywood has low cost, can be processed, low turnover rate, can not help blisters, if If the distance between the small keels is large, and the pressure on the concrete side is large, its own stiffness is low, and bending deformation or even expansion will occur.Generally, the appearance quality of concrete such as foundation slabs or slope roofs is not high or there is no large turnover at a time. Used for parts; plastic formwork is generally shaped, such as the plastic formwork in the multi-ribbed floor, is a formwork for specific structures, and can be rented.
