强化地板吸水厚度膨胀率测定的影响因素分析

Analysis of the Influencing Factors on Determination of Thickness Swelling Rate of Laminate Flooring

以强化地板为研究对象,在保持其他条件不变的情况下,通过改变试件的浸渍温度、浸泡时间、试件尺寸以及试件温湿度的处理条件等因素,分别测试了强化地板的吸水厚度膨胀率,通过对比分析研究它们对测试值的影响。结果表明:随着浸渍温度的升高,强化地板的吸水膨胀率也随之变大;随着浸泡时间的延长,强化地板的吸水膨胀率呈现逐渐升高的趋势,并逐渐趋于缓和;试件尺寸大小对强化地板吸水厚度膨胀率影响较大,随着试件尺寸的增加,强化地板的吸水膨胀率显著减小;不同平衡处理条件下强化地板吸水厚度膨胀率差异较大,高温高湿平衡处理吸水厚度膨胀率降低,低温低湿平衡处理使吸水厚度膨胀率增加。

In this thesis,laminate flooring（Laminate floor covering）is the object of the study. We change the experiment conditions such as water temperature,soaking time,specimen size and THI in the experi-ment with other things being equal. By analyzing the data we got in the experiment,and then summarize the effects of each factor to the laminate flooring. By analyzing the data we got in the experiment,we found that the hygroscopic thickness swelling rate of laminate flooring rises with water temperature increas-ing,with the extended soaking time,but tends to be moderate.And we also found that the numerical values of hygroscopic thickness swelling rate of laminate flooring decrease with the increase of specimen size Burt as to the last factor THI,it’s complex. In the experiment,we found that hygroscopic thickness swelling rate of laminate flooring varies violently in different equilibrium conditions. We found that hygroscopic thickness swelling rate of laminate flooring appears bigger in low temperature and humidity than that before ,while in high temperature and humidity the numerical value of hygroscopic thickness swelling rate of laminate floor-ing appears quite the contrary.
