漆膜圓柱彎曲試驗(yàn)儀是檢測(cè)儀器，用于測(cè)定色漆和清漆的涂膜柔韌性，是衡量涂料性能的主要指標(biāo)之一，對(duì)于涂料品種的選擇。

The paint film cylinder bending tester is a testing instrument for measuring the flexibility of paint films of colored paints and varnishes. It is one of the main indicators for measuring the performance of paints. For the selection of paint varieties.

漆膜圓柱彎曲試驗(yàn)儀參數(shù)：

漆膜彎曲試驗(yàn)器軸的直徑分別為2、3、4、5、6、8、10、12、14、18、20、25、和32、mm

轉(zhuǎn)軸柄調(diào)整數(shù)量大于17mm，與試棒貼緊時(shí)如許縫隙為0.1mm

本儀器適用于1.0mm 以下厚度的樣板。 彎曲半徑不同涂膜對(duì)底材的延展性能亦不同，涂膜依據(jù)在不同彎曲半徑上或剝離情況，而判定涂膜柔韌性的好壞。

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.

漆膜圓柱彎曲試驗(yàn)儀使用與操作：

★按產(chǎn)品標(biāo)準(zhǔn)要求取樣、涂布、干燥并測(cè)厚。

★將QTY—32型漆膜彎曲試驗(yàn)器安放在靠及實(shí)驗(yàn)工作臺(tái)邊緣處，以使調(diào)節(jié)把手能自如操作并插入樣板。

★按產(chǎn)品要求選擇一個(gè)合適的軸棒。插入試驗(yàn)器基座與軸棒空中，并用手動(dòng)鎖母緊固。

★轉(zhuǎn)動(dòng)調(diào)節(jié)手輪降低托板，將樣板的涂膜面向下插入軸棒與調(diào)節(jié)把手之間，并在托板之上用緊固螺釘與壓條將樣板壓緊。

★轉(zhuǎn)動(dòng)調(diào)節(jié)手輪抬起托板使樣板貼緊軸棒。

★放低調(diào)節(jié)把手至A低位置，調(diào)節(jié)把手上的壓緊軸的旋鈕，使壓緊軸貼緊樣板。

★抬起調(diào)節(jié)把手，在1----2S內(nèi)平穩(wěn)而不是突然地抬起180°，此時(shí)軸上的樣板也彎曲180°。

★轉(zhuǎn)動(dòng)調(diào)節(jié)手輪，放低托板，使彎曲樣板離開軸棒而取出。

★樣板檢測(cè)：

彎曲后，不將樣板從儀器上取出，立即檢查樣板，按產(chǎn)品標(biāo)準(zhǔn)要求用正常視力或用10倍放大鏡檢查涂層是否開裂或從底板上剝離（不計(jì)離板邊小于10mm涂層），但需注明使用放大鏡。以便于正常視力結(jié)果造成誤會(huì)。

★認(rèn)定 先引起破壞的軸直徑的操作程序

依據(jù)上述操作，以此（從大到小）實(shí)驗(yàn)較小直徑的軸直至涂膜開裂或從底板上剝離，再將在一塊新的樣板上同樣的軸徑重復(fù)操作，證明這個(gè)結(jié)果后，記錄A先使涂膜開裂或剝離的軸徑。如果A小直徑的軸也不使涂膜破壞，則記錄該涂膜在小直徑的軸上，彎曲時(shí)亦無破壞。

★試驗(yàn)環(huán)境條件

為使結(jié)果判定正確，試驗(yàn)應(yīng)在23±2°C的溫度和50±5%相對(duì)溫度下進(jìn)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-32漆膜圓柱彎曲試驗(yàn)儀使用時(shí)注意事項(xiàng)：

★為了防止在彎曲操作時(shí)破壞涂層，在樣板的涂膜面上可襯附一張薄紙后，再插入托板和調(diào)節(jié)把手之間作試驗(yàn)。

★若使用10倍放大鏡觀察之試驗(yàn)結(jié)果應(yīng)注明。

★使用小的直徑的軸棒也不發(fā)生開裂或剝離，在這種情況下，也應(yīng)注明這個(gè)軸棒的直徑。

★樣板若是鋁板其長(zhǎng)邊應(yīng)平行于壓延方向。

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.
