QTY-32 paint film cylindrical bending tester parameters

The diameter of the paint film bending tester shaft is 2, 3, 4, 5, 6, 8, 10, 12, 14, 18, 20, 25, and 32, mm

The number of adjustment of the shaft handle is more than 17mm, and the gap is 0.1mm when it is in close contact with the test rod.

This instrument is suitable for samples with thickness less than 1.0mm. Coatings with different bending radii have different elongation properties to the substrate. The coating film is based on different bending radii or peeling conditions to determine the flexibility of the coating film.

漆膜圆柱弯曲试验仪使用与操作：

★按产品标准要求取样、涂布、干燥并测厚。

★将QTY—32型漆膜弯曲试验器安放在靠及实验工作台边缘处，以使调节把手能自如操作并插入样板。

★按产品要求选择一个合适的轴棒。插入试验器基座与轴棒空中，并用手动锁母紧固。

★转动调节手轮降低托板，将样板的涂膜面向下插入轴棒与调节把手之间，并在托板之上用紧固螺钉与压条将样板压紧。

★转动调节手轮抬起托板使样板贴紧轴棒。

★放低调节把手至A低位置，调节把手上的压紧轴的旋钮，使压紧轴贴紧样板。

★抬起调节把手，在1----2S内平稳而不是突然地抬起180°，此时轴上的样板也弯曲180°。

★转动调节手轮，放低托板，使弯曲样板离开轴棒而取出。

★样板检测：

弯曲后，不将样板从仪器上取出，立即检查样板，按产品标准要求用正常视力或用10倍放大镜检查涂层是否开裂或从底板上剥离（不计离板边小于10mm涂层），但需注明使用放大镜。以便于正常视力结果造成误会。

★认定 先引起破坏的轴直径的操作程序

依据上述操作，以此（从大到小）实验较小直径的轴直至涂膜开裂或从底板上剥离，再将在一块新的样板上同样的轴径重复操作，证明这个结果后，记录A先使涂膜开裂或剥离的轴径。如果A小直径的轴也不使涂膜破坏，则记录该涂膜在小直径的轴上，弯曲时亦无破坏。

★试验环境条件

为使结果判定正确，试验应在23±2°C的温度和50±5%相对温度下进行。

QTY-32 paint film cylindrical bending tester use and operation:

★ Sampling, coating, drying and thickness measurement according to product standards.

★ Place the QTY-32 type paint film bending tester against the edge of the experimental table, so that the adjustment handle can be freely operated and inserted into the sample plate.

★ Select a suitable shaft rod according to product requirements. Insert the tester base and the shaft into the air and fasten it with the manual lock nut.

★ Turn the adjusting handwheel to lower the supporting plate, insert the coating film of the template face down between the shaft rod and the adjusting handle, and press the sample plate on the supporting plate with fastening screws and strips.

★ Turn the adjustment handwheel to lift the support plate to make the model close to the shaft.

★ Lower the adjusting handle to the A low position, and adjust the knob of the pressing shaft on the handle to make the pressing shaft close to the model.

★ Raise the adjustment handle, and instead of suddenly lifting it 180 ° within 1 ---- 2S, the model on the shaft is also bent 180 ° at this time.

★ Turn the adjusting handwheel to lower the supporting plate to make the bending template leave the shaft and take it out.

★ Sample test:

After bending, do not remove the sample plate from the instrument, immediately check the sample plate, and check whether the coating is cracked or peeled from the bottom plate with normal vision or a 10x magnifying glass (excluding the coating less than 10mm from the edge of the plate), Note the use of a magnifying glass. To facilitate misunderstanding of normal vision results.

★ Identify the operation procedure of the diameter of the shaft that caused the damage first

According to the above operation, use this (large to small) experiment on the smaller diameter shaft until the coating film cracks or peels from the bottom plate, and then repeat the operation on the same shaft diameter on a new sample plate. After proving this result, record A The diameter of the shaft where the coating film is cracked or peeled off first. If the small-diameter shaft does not break the coating film, the coating film is recorded on the small-diameter shaft, and there is no damage during bending.

★ Test environmental conditions

In order to determine the results correctly, the test should be carried out at a temperature of 23 ± 2 ° C and a relative temperature of 50 ± 5%.

QTY-32漆膜圆柱弯曲试验仪使用时注意事项：

★为了防止在弯曲操作时破坏涂层，在样板的涂膜面上可衬附一张薄纸后，再插入托板和调节把手之间作试验。

★若使用10倍放大镜观察之试验结果应注明。

★使用小的直径的轴棒也不发生开裂或剥离，在这种情况下，也应注明这个轴棒的直径。

★样板若是铝板其长边应平行于压延方向。

QTY-32 paint film cylindrical bending tester

★ In order to prevent the coating from being damaged during the bending operation, a thin paper can be lined on the coating film surface of the sample, and then inserted between the support plate and the adjustment handle for testing.

★ If you use 10 times magnifying glass to observe the test results, please indicate.

★ A small diameter shaft does not crack or peel. In this case, the diameter of the shaft should also be indicated.

★ If the sample plate is an aluminum plate, its long side should be parallel to the rolling direction.
