涂層杯突試驗機是**涂層檢測儀器，適用于評價色漆清漆及有關產品的涂層在標準規(guī)定的實驗方法下，進行壓陷試驗，使之逐漸變形后，其涂層的抗開裂或抗與金屬底材分離的性能，評定涂層通過或不通過。也可逐漸增加壓陷深度，以測定涂層剛出現(xiàn)開裂或開始脫離底材的小深度。

The coating cupping tester is a testing instrument for coatings. It is suitable for evaluating the coatings of paints and varnishes and related products. Under the standard test method, a depression test is performed to gradually deform the coatings. For cracking or resistance to separation from metal substrates, evaluate whether the coating has passed or failed. It is also possible to gradually increase the depression depth to determine the small depth at which the coating has just cracked or has started to detach from the substrate.

涂層杯突試驗機依據國際標準ISO1520和**標準GB9753—88設計制造。

The coating cup burst tester is designed and manufactured according to the international standard ISO1520 and ** standard GB9753-88.

（3）試片按標準要求制備涂層，進行干燥，測量其厚度。在溫度23±2°C，相對濕度50±5%的環(huán)境下，進行狀態(tài)調節(jié)至少16小時后方可投入試驗。

Test procedure and operation method of QBJ coating cup protrusion tester

★ Preparation of test strips

(1) The test piece is square, and its size is 70mm * 70mm * 0.03mm ~ 1.25mm

(2) The material of the test piece should be polished steel and meet the requirements of GB9271. The test piece should be flat and not deformed.

(3) Prepare the coating of the test piece according to the standard, dry it, and measure its thickness. Under the environment of temperature 23 ± 2 ° C and relative humidity 50 ± 5%, adjust the state for at least 16 hours before putting it into the test.

QBJ涂層杯突試驗機操作方法：

★單面涂層板的試驗：——自動調零

將試驗機手輪朝下降方向（順時針方向）旋到底，松動試驗機上部試片壓緊裝置，將單面涂層試板金屬面朝下，涂層面朝上插入試驗機上部的夾縫中，并使沖頭對準該試片的**軸線，緊固壓緊裝置。按一下儀表紅色清零按鈕，顯示器顯示為零。以0.2±0.1mm/s（即2~3秒一圈）的速度向上升方向（逆時針方向）轉動手輪。當讀數到達0.40mm左右時，沖頭碰到試板金屬面，顯示器自動顯示零點，此時儀器紅燈亮。再繼續(xù)轉動手輪，顯示器讀數即為上升高度，也**是壓陷深度，進行中A逆轉，否則讀數不準。

★雙面涂層板的試驗，——手動調零

將試驗機手輪朝下降方向（順時針方向）旋到底，松動試驗機上部試片壓緊裝置，用隨機的調零鋼板插入試驗機上部的夾縫中，緊固壓緊裝置。按一下儀表紅色按鈕，使顯示器顯示為零。以上升方向（逆時針方向）轉動手輪，當讀數接近1.80mm時，放慢速度。當儀器紅色燈亮時，也**是顯示器為零時，停止轉動手輪。松開壓緊裝置，再手動清零（按一下儀表紅色 按鈕），以0.2±0.1mm/s速度向上升方向轉動手輪，顯示器讀數為上升高度也**是壓陷深度。

★以校正過的視力或10倍放大鏡，檢查試片上的涂層是否開裂或從底材上分離。

★上述程序應在兩塊單獨的試片上進行，若結果不同，應補充試驗，至兩塊試片結果一致。若底材出現(xiàn)裂紋，則該實驗結果無效。

★當試片上的涂層次出現(xiàn)開裂，或涂層從底材上分離時，沖頭停止移動（顯示器上的數字為推進深度）上述試驗需在同一種的底材上重復進行，以驗證其結果，直至一致。

Operation method of QBJ coated cup protrusion tester

★ Single-sided coated board test:-Automatic zero adjustment

Turn the handwheel of the testing machine downward (clockwise) to the bottom, loosen the test piece pressing device on the upper part of the testing machine, insert the single-sided coated test plate with the metal side facing downwards, and insert the coated side upwards into the gap between the upper part of the testing machine , And align the punch with the ** axis of the test piece, and tighten the pressing device. Press the meter's red zero button once, the display shows zero. Turn the handwheel in the upward direction (counterclockwise) at a speed of 0.2 ± 0.1mm / s (that is, one revolution in 2 to 3 seconds). When the reading reaches about 0.40mm, the punch hits the metal surface of the test plate, the display automatically displays the zero point, and the red light of the instrument is on. Then continue to turn the handwheel, the display reading is the rising height, and is also the depression depth, A is reversed during the process, otherwise the reading is not accurate.

★ Test of double-sided coated board, —— manual zero adjustment

Turn the hａnd wheel of the testing machine downwards (clockwise) to the bottom, loosen the test piece pressing device on the upper part of the testing machine, insert the random zero-adjusting steel plate into the gap between the upper part of the testing machine, and tighten the pressing device. Press the meter's red button once to make the display zero. Turn the handwheel in the upward direction (counterclockwise). When the reading approaches 1.80mm, slow down. When the red light of the instrument is on, and when the display is zero, stop turning the handwheel. Loosen the compaction device, and then clear it manually (press the red button of the meter), and turn the handwheel in the rising direction at a speed of 0.2 ± 0.1mm / s. The display reads the rising height and the depression depth.

★ With corrected vision or a 10x magnifying glass, check whether the coating on the test piece is cracked or separated from the substrate.

★ The above procedure should be performed on two separate test strips. If the results are different, the test should be supplemented until the results of the two test strips are consistent. If cracks occur on the substrate, the results of this experiment are invalid.

★ When the coating on the test piece cracks or the coating is separated from the substrate, the punch stops moving (the number on the display is the depth of advance). The above test needs to be repeated on the same substrate to verify its As a result, until agreement.
