上海荣计达20×20×4高温流淌性测定仪 流淌性测定仪

一，产品简介：

高温流淌性测定仪根据12953-2003，GB/18173-2000GB/T328-2007之规范设计制作。用于防水卷材的高温流淌性的检测。First, the product introduction:The high temperature flow tester is designed and manufactured according to the specifications of 12953-2003, GB/18173-2000GB/T328-2007. It is used for the detection of high temperature flowability of waterproof coiled materials.

二，试验方法： 将三个20mm×20mm×4mm的试样分别置于75°倾角的带凹槽木架上，使试样厚度的2mm在槽内，2mm在槽外；一并放入（80±2）℃的干燥箱内，5h后取出，观察试样有无明显流淌，以不超过凹槽边线1,mm为无流淌。Second, the test method:Place three 20mm × 20mm × 4mm specimens on a grooved wooden frame with an inclination of 75°, so that the thickness of the sample is 2mm in the groove and 2mm outside the groove; put together (80±2) °C In the dry box, take it out after 5 hours, and observe whether the sample has obvious flow, so as not to exceed the groove edge line 1, mm is no runny.三，操作使用： 1、高温流淌性试验：将三个20×20×4mm的试样分别置于75°倾角的带凹槽木架上，使试样厚度的2mm在槽内，2mm在槽外；一并放人(80土2)℃的干燥箱内，5h后取出，观察试样有无明显流淌，以不超过凹槽边线l mm为无流淌。三个试件均不流淌为合格。2、低温试验：将试样切、压成50×100×2mm的试件2片，在(-20土2)℃低温箱中停放2h，取出后立即在#10mm的棒上软绕一圈，观察其是否脆裂，2片均不脆裂为合格。 3、止水条试验结果评定：依据《高分子防水材料第3部分遇水膨胀橡胶》（GB18173.3--2002）评定腻子型止水条以上三项试验结果均应符合规定。Third, the operation uses:1. High temperature flowability test: Three 20×20×4 mm samples were placed on a grooved wooden frame with an inclination of 75°, so that the thickness of the sample was 2 mm in the groove and 2 mm outside the groove;Put it in a dry box (80 soil 2) °C, take it out after 5h, and observe whether the sample has obvious flow, so as not to exceed the groove edge line l mm as no runny. None of the three test pieces were qualified.2. Low temperature test: Cut and compress the sample into 2 pieces of 50×100×2mm test piece, park it in the (-20 soil 2) °C low temperature box for 2 hours, and immediately take a soft circle on the #10mm rod after taking out. Observe whether it is brittle or not, and both pieces are not brittle and qualified.3. Evaluation of test results of water stop strips: According to the “Polymer waterproofing material part 3 water-swellable rubber” (GB18173.3--2002), the results of the three test tests above the putty type water stop strip shall comply with the regulations.
