Paint film back viscosity tester maintenance and maintenance:
  After the end of the experiment, the bottom area of the paint film back viscosity tester should be cleaned, put into the instrument box, and placed in a clean and dry place to prevent corrosion and affect the use of the instrument.

 

动态抗开裂测试仪自动动态抗开裂测动态抗开裂性试验机工作原理

由于建筑物的不均匀的干湿变化、热胀冷缩、结构沉降及设计、施工上的不完整等原因,几乎所有建筑都不同程度地存在表面毛细裂缝、表面贯通裂缝、结构性裂缝。

外墙裂缝不仅大大降低了对建筑物外墙的保护作用,也给涂饰面的美观造成了一定的影响。为了弥补上述之缺陷,在涂刷外墙乳胶漆之前,必先在墙体涂刮一层外墙腻子;而外墙腻子的质量优劣,则是关键之关键。

测试仪依据JG/T157-2004行标设计制造的QDK型自动动态抗开裂测试仪适用于测试以水泥、聚合物粉末、合成树脂乳液或其它材料为主要粘结剂,配以填料、助剂等组成的外墙找平腻子。

电机通过齿轮减速后拖动顶杆作上升运动,刃口产生上顶力,使石棉水泥板在规定的区域内逐步产生细微裂纹并控制裂纹缓慢扩展,观察腻子层的开裂情况,以此表征腻子抵抗基材裂纹扩展的能力。

Automatic dynamic anti-crack tester works:
★ Due to the uneven dry and wet changes of the building, thermal expansion and contraction, structural settlement and incomplete construction and construction, almost all buildings have surface capillary cracks, surface through cracks and structural cracks.
★ The cracks on the external wall not only greatly reduce the protection of the exterior wall of the building, but also have a certain impact on the aesthetic appearance of the painted surface. In order to make up for the above defects, before applying the exterior latex paint, a layer of external wall putty must be applied to the wall; and the quality of the external wall putty is the key.
★The QDK automatic dynamic anti-crack tester designed and manufactured according to JG/T157-2004 is suitable for testing cement, polymer powder, synthetic resin emulsion or other materials as the main binder, with fillers and additives. The outer wall of the composition is equalized with putty.
★When the motor is decelerated by the gear, the ejector rod is dragged to make the ascending motion, and the top edge generates the topping force, so that the asbestos cement board gradually produces fine cracks in the specified area and controls the crack to spread slowly, and observes the cracking of the putty layer. The ability of the putty to resist crack propagation of the substrate.

动态抗开裂测试仪自动动态抗开裂测动态抗开裂性试验机使用试验方法

将型框放在200×150(mm)的石棉水泥板上。在将配制好的腻子涂刮在型框内。

将型框取下,涂刮好的石棉水泥板应在标准环境下养护7d。每一样品应同时制备3块试板。

将养护好的试板卡固在本仪器的工作台面上。启动电源开关后在启动上升开关,此时刃口缓慢上升。

刃口继续缓慢上升。此时应注意观察石棉板的空白区域,当发现裂纹出现后,使用立式读数显微镜观察并随时记录裂纹宽度,至腻子层开裂前为止。启动停止开关后,刃口不再上升。

记录腻子层开裂前,石棉水泥板裂缝的A大宽度。精确到0.02 mm。

启动下降开关,使刃口退回原位。

松开试板卡固螺母及压板,取下试板。在放入另一块试板,重复上述试验步骤。

QDK automatic dynamic anti-crack tester using test method
★ Place the frame on a 200×150 (mm) asbestos cement board. The prepared putty is scraped into the frame.
★ Remove the frame, and the coated asbestos cement board should be cured for 7 days under standard conditions. Three test panels should be prepared simultaneously for each sample.
★ Fix the cured test board to the work surface of the instrument. After the power switch is turned on, the rise switch is activated, and the cutting edge slowly rises.
★ The cutting edge continues to rise slowly. At this point, attention should be paid to the blank area of the asbestos board. When cracks are found, use a vertical reading microscope to observe and record the crack width until the layer of the putty layer is cracked. After starting the stop switch, the cutting edge no longer rises.
★ Record the A width of the crack in the asbestos cement board before the cracking of the putty layer. Accurate to 0.02 mm.
★ Start the down switch to return the cutting edge.
★ Loosen the test plate retaining nut and pressure plate and remove the test plate. Repeat the above test procedure while placing another test plate.

 

动态抗开裂测试仪自动动态抗开裂测动态抗开裂性试验机结果判断

三块试板中以数值较近的每块试板的测试结果的算术平均值作为A终结果。

QDK automatic dynamic anti-crack tester results judge
The arithmetic mean of the test results of each of the three test plates in the three test plates was taken as the final result of A.
