Gypsum board moisture deflection test box

SCN-60 typeGypsum board moisture deflection test boxTrial scope:

According to the national standardDesigned and manufactured according to the standard curing requirements for test specimens in GB/T9775-2008 "Line Surface Gypsum Board" and JC/T799-2016 "Decorative Gypsum Board".

Mainly used for moisture deflection test of gypsum board, the interior is made of stainless steel plate, and the insulation layer is made of glass rock wool, which has good insulation and sealing properties. Equipped with heating equipment, excellent intelligent instruments and high-precision digital sensors are used for temperature and humidity. It is an ideal equipment for scientific research institutions, quality inspection departments, and on-site laboratories to maintain test specimens.

SCN-60 typeGypsum board moisture deflection test boxTest method:

Suspend the three specimens dried to a constant weight facing downwards on the supports of the three test stands of the moisture deflection tester, with the center distance of the supports being the length of the specimen minus20mm， Place the test piece in the deflection test chamber at a temperature of (32 ± 2) ℃ and a relative humidity of (90 ± 3)% for 48 hours. Use a dedicated measuring ruler to measure the sag of the middle part of the test piece on each test stand before and after moisture exposure, and record the increase in sag after moisture exposure, which is the moisture tolerance of the test piece.

Record the average moisture deflection of three specimens and record the maximum value, accurate to1mm。
