二、石膏受潮挠度测定仪技术参数
★装饰石膏板受潮挠度测定仪是根据JC/T799-2007标准设制的。
★使用环境：水泥养护实验室：温度在（32+2），相对湿度（90+3）
★装饰石膏板受潮挠度测定仪检测样品：500X250X9或600X300X11(mm)的3组。
★按试验要求需要配3套夹具，每套夹具都配精度为0.01mm的专用尺和水平尺各一把。
★将试块烘干，然后将每块试件正面向下，分别悬放在受潮扰度测定仪试验箱中三个试验架的支座上，支座 距为试件长度减去20mm，在文档为32度空气相对湿度90度条件下，讲试件放置48h，来源专用测量头。
★外形尺寸:600*500mm
★ 重量：40kg
★受潮挠度的测定仪规定的3块试件按5．3条烘干至恒重，然后将每块试件正面向下，分别悬放在受潮挠度测定仪试验箱中三个试验架的支座上，支座 距为试件长度减去 20mm。在温度为32±2℃，空气相对湿度为90％±3％条件下，将试件放置48h。然后将试件连同试验架从试验箱中取出，利用专用的测量头，分别测定每个试验架上试件中部的下垂挠度。计算3个块试件受潮挠度的平均值，并记录其中的A大值，精确至lmm。
Second, the technical parameters of gypsum moisture deflection tester
★ Decorative gypsum board moisture deflection tester is based on JC / T799-2007 standard.
★ Environment: Cement Conservation Lab: Temperature at (32 + 2), relative humidity (90 + 3)
★ Decorative gypsum board moisture deflection tester: 500X250X9 or 600X300X11 (mm) 3 groups.
★ According to the test requirements, 3 sets of fixtures are required, and each set is equipped with a dedicated ruler and a level ruler with an accuracy of 0.01mm.
★ Dry the test pieces, then suspend each test piece face down and suspend it on the supports of the three test stands in the test box of the moisture disturbance meter. The center distance of the support is the length of the test piece minus 20mm. Under the condition that the relative humidity of the document is 32 degrees and 90 degrees, the test piece is placed for 48 hours and the source is a special measuring head.
★ Dimensions: 600 * 500mm
★ Weight: 40kg
★ The three test pieces specified by the moisture deflection tester are dried to constant weight according to 5.3, and then each test piece is face down and suspended on the support of three test racks in the test box of the moisture deflection tester. On the seat, the center distance of the support is the length of the test piece minus 20mm. At a temperature of 32 ± 2 ° C and a relative humidity of 90% ± 3%, the test piece was left for 48 hours. Then remove the test piece from the test box together with the test rack, and use a special measuring head to measure the sagging deflection of the middle of the test piece on each test rack. Calculate the average value of moisture deflection of the three test pieces, and record the large A value to the nearest 1 mm.
