In order to produce high-density and more healthy material products, the continuous press production process must be adopted.At present, the production of continuous press is the most stable and more healthy with the product specifications within 7 ~ 8 mm.

Higher or lower than this range can lead to the overall performance of the product defects.Floor enterprises believe that the evaluation of quality by the thickness of the experts believes that, theoretically, the market is 8 mm thick floor.If the standard manufacturer produces the qualified product density of more than 850 kg/m3, the density curve is in English "U"shape.

Generally speaking, the density of the upper and lower surface is much higher than the middle density.This density distribution is required because the upper and lower surface should be tightly tied with the impregnated paper at high temperature and high pressure without falling off.
