詳細介紹

防水卷材低溫彎折儀是檢測儀器，用于高分子卷材和防水涂料的低溫彎折性試驗；也適合防水涂料的低溫柔性測定。使用前務(wù)必仔細閱讀說明書。并由實驗人員操作，以避免操作不當(dāng)引起的傷害。如需了解更多資料請與我公司客服人員聯(lián)系。

The low-temperature bending tester of waterproof coil is a testing instrument for low-temperature bending test of polymer coils and waterproof coatings. It is also suitable for low-temperature flexibility measurement of waterproof coatings. Be sure to read the instructions carefully before use. It is operated by experimental personnel to avoid injury caused by improper operation. For more information, please contact our customer service staff.

DW-120防水卷材低溫彎折儀構(gòu)成：

彎折儀主要由金屬材料制成的上、下平板，轉(zhuǎn)軸和調(diào)距螺桿組成。

平板間距可任意調(diào)節(jié)

試件尺寸：100*50mm ；

彎折角度：180°；

DW-120 waterproof coil bending instrument composition:

The bending instrument is mainly composed of upper and lower flat plates made of metal materials, a rotating shaft and a pitch adjusting screw.

Plate spacing can be adjusted arbitrarily

Test piece size: 100 * 50mm;

Bending angle: 180 °;

DW-120防水卷材低溫彎折儀使用方法：

★在標(biāo)準(zhǔn)環(huán)境下，用規(guī)定的測厚儀(厚度計)測量試樣的厚度。

★在試樣的橫向和縱向各取100×50/50×100mm的試樣兩塊。

★將試樣的的耐厚秒年朝外，彎曲180°，使50mm寬的邊緣重合，齊平，并確保不發(fā)生錯位，(可用定位夾或10nn寬的膠布將邊緣固定)。

★將彎折儀的上下兩平板間距調(diào)到被測卷材的三倍后，再將彎折儀上下平板翻開，將同一方向的兩塊試樣放在彎折儀的下平板上，重合的一邊朝向轉(zhuǎn)軸并與刻度線防齊。

★整體防入低溫箱內(nèi)，在規(guī)定溫度下保持1h,然后1S之內(nèi)將上平板翻下到所調(diào)的間距位置，保持1S 后，取出試樣。

★恢復(fù)到室溫后，觀察試樣彎折處是否斷裂，或用放大觀察試樣彎折處受拉面是否有裂紋

★低溫彎折儀四、結(jié)構(gòu)評定

★兩塊試驗均不斷裂或無斷紋時，評定為無斷裂。

★注(1)以標(biāo)準(zhǔn)GB12592-2003(聚氯乙烯防水材料)為例。其他材料使用方法應(yīng)參其相應(yīng) 標(biāo)準(zhǔn)或行標(biāo)中的試驗方法進行。

How to use DW-120 waterproof coil low temperature bending instrument:

★ In a standard environment, use a specified thickness gauge (thickness gauge) to measure the thickness of the sample.

★ Take two samples of 100 × 50/50 × 100mm each in the horizontal and vertical directions of the sample.

★ Bend the thickness of the sample outwards for 180 seconds, make the edges of 50mm width coincide, flush, and ensure that no misalignment occurs (the positioning edge or 10nn wide tape can be used to fix the edges).

★ After adjusting the distance between the upper and lower plates of the bender to three times the measured coil, turn the upper and lower plates of the bender and place the two samples in the same direction on the lower plate of the bender and overlap. The side facing toward the axis of rotation is aligned with the tick mark.

★ Prevent the whole from entering the low temperature box, keep it at the specified temperature for 1h, and then turn the upper plate down to the adjusted distance within 1S, and hold the sample for 1S.

★ After returning to room temperature, observe whether the bending part of the sample is broken, or use magnification to observe whether the tensile surface of the sample bending part is cracked.

★ Low Temperature Bending Instrument

★ When neither test is broken or broken, it is evaluated as no break.

★ Note (1) Take standard GB12592-2003 (polyvinyl chloride waterproof material) as an example. The use of other materials should be carried out in accordance with the test methods in their respective standards or standards.
