经分析计算，基本密度为０．３６ｇ／ｃｍ￣３的木材，在１２０％的含水率状态下木材中细胞壁物质、水和空气三者的体积比约为１：１：１，因此当该木材体积压榨率达到６６％时，木材中的水分（自由水）几乎将被全部挤出。据此，使用表面有沟槽的几种不同模板对速生树种Ｉ－６９杨和火炬松的生材单板进行了不同压榨车的挤水试验，结果表明：Ｉ－６９杨２．０２ｍｍ生材单板用７０％的压榨率挤压后，含水率显著降低，组内试件间的合水率差异显著缩小；火炬松２．３８ｍｍ和３．３３ｍｍ生材单板，压榨率６０％比４０％的挤水量大、挤后与挤前组内含水率极差比值小，因而达到了降低并均匀生材单板含水车的目的。另外，模板不同也显出不同的挤水效果。
After analysis and calculation, the basic density of 0.36g / cm ~ 3 of wood, the moisture content of 120% of the state of wood in the cell wall material, water and air volume ratio of about three of the 1: 1: 1, so when the timber When the volumetric crushing rate reaches 66%, the moisture (free water) in the wood is almost completely squeezed out. According to the above results, the squeezing tests on different raw materials of I-69 Yang and Pinus taeda were carried out by using several different templates with grooves on the surface. The results showed that: I-69 Yang 2.02mm raw material When the veneer was squeezed with the pressing rate of 70%, the water content decreased significantly, the difference between the combined water rates among the samples in the group was significantly reduced; the loblolly pine 2.38mm and 3.33mm veneer, the pressing rate of 60% to 40 % Of the amount of water squeeze, after extrusion and extrusion before the group within the ratio of the water content is small, so as to achieve the goal of reducing and even uniform raw material water board. In addition, different templates also show different water squeezing effect.
