外墙外保温系统抗冲击试验仪概述:

抗冲击性试验仪是根据外墙外保温系统材料标准要求制作,钢球符合GB/T308标准要求,公称直径50.8mm/63.6mm的高碳铬轴承钢;由钢球、落球装置、支架等配件组成。

Overview of impact tester for external wall insulation system:

The impact resistance tester is manufactured according to the material requirements of external insulation systems for external walls. The steel balls meet the requirements of the GB / T308 standard and high-carbon chromium bearing steel with a nominal diameter of 50.8mm / 63.6mm. composition.


外墙外保温系统抗冲击试验仪主要技术参数:

★钢球直径50.8mm(535g)/63.6mm(1045g)

★大冲击高度:1200mm

★净重:≈80kg

Main technical parameters of impact tester for external wall insulation system:

★ Steel ball diameter 50.8mm (535g) /63.6mm (1045g)

★ High impact height: 1200mm

★ Net weight: ≈80kg


外墙外保温系统抗冲击试验仪使用和维护:

★试件的制作 

试样尺寸宜大于600*400mm,每一抗冲击**别数量为1个。试样在标准养护条件下养护14天,然后在室温水中浸泡7天,饰面层向下,浸入水中3-10mm。试样从水中取出后,在试验环境下状态调节7天。

★试验

将试样饰面层向上,水平放置在抗冲击仪器是基底上,试样紧贴基底。

3J**:用公称直径50.8mm的钢球冲击,钢球的A底点距被冲击试样垂直高度为0.57米。此冲击强度为3J**。

10J**:用公称直径63.5mm的钢球冲击,钢球的A底点距被冲击试样垂直高度为0.98米。此冲击强度为10J**。

每一**别冲击10次。冲击点间距与边缘的距离不小于100mm,试样表面冲击及周围出现裂缝视为冲击点破坏。

Use and maintenance of impact tester for external wall insulation system

★ Production of test pieces

The size of the sample should be greater than 600 * 400mm, and each impact resistance ** is one. The samples were cured for 14 days under standard curing conditions, then immersed in room temperature water for 7 days, facing down, and immersed in water for 3-10mm. After the sample was taken out of the water, it was adjusted in the test environment for 7 days.

★ Experiment

Place the sample facing layer upwards and place it horizontally on the base of the impact-resistant instrument, with the sample firmly against the base.

3J **: Impacted by a steel ball with a nominal diameter of 50.8mm, the vertical height of the bottom point of the steel ball from the impacted sample is 0.57 meters. This impact strength is 3J **.

10J **: Impacted by a steel ball with a nominal diameter of 63.5mm, the vertical height of the bottom point of the steel ball from the impacted specimen is 0.98 meters. This impact strength is 10J **.

Don't impact 10 times per **. The distance between the impact point and the edge is not less than 100mm. The impact on the surface of the sample and the cracks around it are regarded as the impact point failure.


外墙外保温系统抗冲击试验仪实验结果:

3J试验10个冲击点中破坏点小于4个时,评定为3J**,

10J试验10个冲击点中破坏点小于4个时,评定为10J**,

Experimental results of impact tester for external wall insulation system

In the 3J test, if there are less than 4 failure points in 10 impact points, the evaluation is 3J **,

In the 10J test, if there are less than 4 failure points in 10 impact points, the evaluation is 10J **,
