浸渍纸层压地板湿度65%-30%情况下尺寸收缩率检测数据

浸渍纸层压实木复合地板湿度65%-30%情况下尺寸收缩率是产品是否达标的一项重要且强制性标准，收缩率越少，代表产品的品质越好，本数据对实木复合地板用胶合板湿度65%-85%情况下尺寸收缩率作出检测，为企业生产做出参考。1、产品检测：对浸渍纸层压实木复合地板进行抽样检测，每次检测样本温度保持在18~22℃，在相对湿度85%的情况下，测出样本长度并记录，然后同一样本在相对湿度65%的情况下，测出样本长度并记录；2、数据处理：尺寸变化值=|在65%相对湿度下的尺寸-在30%相对湿度下的尺寸|，收缩率=尺寸变化值*1000/在65%相对湿度下的尺寸；3、对比国家标准，若样本中收缩率≤1.2mm/m则认为该样本合格，否则为不合格；4、对实木复合地板用胶合板湿度65%-85%情况下尺寸收缩率的检验检测，为企业生产标准化生产做出有效参考。The dimensional shrinkage rate of impregnated paper laminated solid wood composite flooring under the condition of relative humidity shifting from 65% to 30% serves as an important and mandatory criterion for product compliance assessment. The lower the shrinkage rate, the better the product quality. This dataset performs tests on the dimensional shrinkage rate of plywood for solid wood composite flooring at relative humidity ranging from 65% to 85%, offering valid references for enterprise production. 1. Product Testing: Conduct sampling tests on impregnated paper laminated solid wood composite flooring. Keep the temperature of each test sample within 18–22℃. Measure and record the length of the sample under 85% relative humidity, then measure and record the length of the identical sample under 65% relative humidity. 2. Data Processing: Dimensional change value = |Dimension at 65% relative humidity − Dimension at 30% relative humidity|; Shrinkage rate = (Dimensional change value × 1000) / Dimension at 65% relative humidity. 3. National Standard Compliance: A sample is considered qualified if its shrinkage rate is ≤1.2 mm/m; otherwise, it is deemed unqualified. 4. The test and inspection of the dimensional shrinkage rate of plywood for solid wood composite flooring under 65%–85% relative humidity provides effective references for the standardized production of enterprises.
