一，產(chǎn)品簡介：
高溫流淌性測定儀根據(jù)12953-2003，GB/18173-2000GB/T328-2007之規(guī)范設計制作。用于防水卷材的高溫流淌性的檢測。
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，試驗方法：
將三個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，觀察試樣有無明顯流淌，以不超過凹槽邊線1,mm為無流淌。
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、高溫流淌性試驗：將三個20×20×4mm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；
一并放人(80土2)℃的干燥箱內(nèi)，5h后取出，觀察試樣有無明顯流淌，以不超過凹槽邊線l mm為無流淌。三個試件均不流淌為合格。
2、低溫試驗：將試樣切、壓成50×100×2mm的試件2片，在(-20土2)℃低溫箱中停放2h，取出后立即在#10mm的棒上軟繞一圈，觀察其是否脆裂，2片均不脆裂為合格。
3、止水條試驗結果評定：依據(jù)《高分子防水材料第3部分遇水膨脹橡膠》（GB18173.3--2002）評定膩子型止水條以上三項試驗結果均應符合規(guī)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.
