一，20×20×4高溫流淌性測(cè)定儀產(chǎn)品簡(jiǎn)介：

高溫流淌性測(cè)定儀根據(jù)12953-2003，GB/18173-2000GB/T328-2007之規(guī)范設(shè)計(jì)制作。用于防水卷材的高溫流淌性的檢測(cè)。
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.

二，20×20×4高溫流淌性測(cè)定儀試驗(yàn)方法：
將三個(gè)20mm×20mm×4mm的試樣分別置于75°傾角的帶凹槽木架上，使試樣厚度的2mm在槽內(nèi)，2mm在槽外；一并放入（80±2）℃的干燥箱內(nèi)，5h后取出，觀察試樣有無(wú)明顯流淌，以不超過(guò)凹槽邊線(xiàn)1,mm為無(wú)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.
