On the other hand, the Suppression of the substrate in the process of hot-pressing parameters (time, pressure, track matching a certain degree of temperature also affects the formaldehyde emission.Only by large-scale automatic continuous press in order to produce high-density substrate to meet the requirements.The function of the equipment itself and the process control can make the free formaldehyde release in the controlled state of the process and ensure that the standard of the healthy floor product is met.According to the working condition of the international mainstream continuous press, the production of the base material within 8 mm is not only the most stable density curve, but also ensures the better standard.
To meet the basic requirements of the quality and functional properties of aggrandizement wood floor is 7-8mm high-density substrate thickness of the mainstream production technology.At present, most of the non-8-mm thick materials are used in the multi-layer press.This equipment is not enough and the inter-layer density and the density of the product cannot be avoided and the uneven distribution of the density of planar defects.
