Hardwood flooring is a multi-layer for the substrate, made from the skin surface mount solid wood flooring. Substrate types of raw materials and processing technology can lead to bending flooring products. Cause distortion factor can be summarized as follows: 1, the impact of multi-layer parquet base raw material (board) with the same species, similar shrinkage coefficient of wood substrate deformation. Sometimes the use of hardwood, especially different densities of wood, wood shrinkage coefficient mixed group of different blank on both sides of the central layer of the substrate is formed asymmetrical stress caused by bending or distortion floor substrate. Therefore, if the choice of hardwood as a raw material wood flooring substrate, should try to use the proportion of timber and timber similar species. Symmetrical layer on both sides of the center layer in the substrate try to use the same species. If conditions permit, the company can be purchased by species and wood properties of raw materials sorting.
2, the impact of multi-layer parquet veneer moisture content in the veneer moisture content distribution is large, for example, in the same piece of substrate slabs, some veneer moisture rate of 7%, some veneer moisture 14%, after gluing, pressing, finished the base plate of various parts of the uneven distribution of moisture, though, when the base plate is flat out just the press, when the water content rebalancing will occur bending and distortion. If the individual regions slab moisture content is too high, it will produce stratification. Therefore, we should try to control the moisture content of the board within the scope of process requirements. Veneer coating should be uniform, it can be extended aging time, so that the moisture content of the slab before pressing individual layers and points to achieve balance.
3, multi-layer parquet board inside the base stack (overlapping) from (from the seam) effects stacked inside the base plate from the plate will generate stress, this stress generated in the entire base plate is not very clear When the base plate when sawing into floor bar, stacked from stress point will lead to multi-layer parquet strips deformed. If there is a serious stack in the three surface when, made of poured paint wood flooring in the use of the process in the stack at (0.6mm thickness of the surface layer) clearly visible edges. Therefore, the board must be spliced, so that the entire , reducing and avoiding the plate from the stack.
