二、石膏受潮撓度測定儀技術(shù)參數(shù)
★裝飾石膏板受潮撓度測定儀是根據(jù)JC/T799-2007標(biāo)準(zhǔn)設(shè)制的。
★使用環(huán)境：水泥養(yǎng)護(hù)實(shí)驗(yàn)室：溫度在（32+2），相對濕度（90+3）
★裝飾石膏板受潮撓度測定儀檢測樣品：500X250X9或600X300X11(mm)的3組。
★按試驗(yàn)要求需要配3套夾具，每套夾具都配精度為0.01mm的專用尺和水平尺各一把。
★將試塊烘干，然后將每塊試件正面向下，分別懸放在受潮擾度測定儀試驗(yàn)箱中三個試驗(yàn)架的支座上，支座 距為試件長度減去20mm，在文檔為32度空氣相對濕度90度條件下，講試件放置48h，來源專用測量頭。
★外形尺寸:600*500mm
★ 重量：40kg
★受潮撓度的測定儀規(guī)定的3塊試件按5．3條烘干至恒重，然后將每塊試件正面向下，分別懸放在受潮撓度測定儀試驗(yàn)箱中三個試驗(yàn)架的支座上，支座 距為試件長度減去 20mm。在溫度為32±2℃，空氣相對濕度為90％±3％條件下，將試件放置48h。然后將試件連同試驗(yàn)架從試驗(yàn)箱中取出，利用專用的測量頭，分別測定每個試驗(yàn)架上試件中部的下垂撓度。計(jì)算3個塊試件受潮撓度的平均值，并記錄其中的A大值，精確至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.
