Waterproof coil low temperature bending instrument is a professional testing instrument for low temperature bending test of polymer coil and waterproof coating; also suitable for low temperature flexible measurement of waterproof coating. Be sure to read the instructions carefully before use. It is operated by professional experimenters to avoid injury caused by improper operation. For more information, please contact our customer service staff.

 

低温卷材弯折仪,低温弯折仪构成:

弯折仪主要由金属材料制成的上 、下平板,转轴和调距螺杆组成。

平板间距可任意调节

试件尺寸:100*50mm ;

弯折角度:180°;

重量:12kg

DW-120 waterproof coil material low temperature bending instrument consists of:
★The bending instrument is mainly composed of upper and lower plates made of metal materials, rotating shaft and adjusting screw.
★Plate spacing can be adjusted freely
★ Sample size: 100*50mm;
★ bending angle: 180°;
★ Weight: 12kg

 

低温卷材弯折仪,低温弯折仪使用方法:

在标准环境下,用规定的测厚仪(厚度计)测量试样的厚度。

在试样的横向和纵向各取100×50/50×100mm的试样两块。

将试样的的耐厚秒年 朝外,弯曲180°,使50mm宽的边缘重合,齐平,并确保不发生错位,(可用定位夹或10nn宽的胶布将边缘固定)。

将弯折仪的上下两平板间距调到被测卷材的三倍后,再将弯折仪上下平板翻开,将同一方向的两块试样放在弯折仪的下平板上,重合的一边朝向转轴并与刻度线防齐。

整体防入低温箱内,在规定温度下保持1h,然后1S之内将上平板翻下到所调的间距位置,保持1S 后,取出试样。

恢复到室温后,观察试样弯折处是否断裂,或用放大观察试样弯折处受拉面是否有裂纹

低温弯折仪四、结构评定

两块试验均不断裂或无断纹时,评定为无断裂。

(1)以国家标准GB12592-2003(聚氯乙烯防水材料)为例。其他材料使用方法应参其相应国家标准或行标中的试验方法进行。

DW-120 waterproof coil material low temperature bending instrument use method:
★In a standard environment, measure the thickness of the sample with a specified thickness gauge (thickness gauge).
★ Take two samples of 100×50/50×100mm in the lateral and longitudinal directions of the sample.
★The thickness of the specimen is turned outwards, bent 180°, so that the edges of 50mm width are coincident, flush, and ensure that no misalignment occurs (the edge can be fixed with a positioning clip or a 10nn wide tape).
★ After adjusting the spacing between the upper and lower plates of the bending instrument to three times the measured coil, the upper and lower plates of the bending instrument are turned over, and two samples in the same direction are placed on the lower plate of the bending instrument, overlapping One side faces the shaft and is aligned with the tick mark.
★In the whole anti-low temperature box, keep it at the specified temperature for 1h, then turn the upper plate down to the adjusted position within 1S. After 1S, take out the sample.
★ After returning to room temperature, observe whether the bend of the sample is broken, or use the magnified view to see if the tensile surface of the sample is cracked.
★Cryogenic bending instrument IV. Structural evaluation
★ When both tests are not broken or there are no broken lines, it is evaluated as no break.
★ Note (1) Take the national 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 national standards or standards.
