　　涂层杯突试验机是**涂层检测仪器，适用于评价色漆清漆及有关产品的涂层在标准规定的实验方法下，进行压陷试验，使之逐渐变形后，其涂层的抗开裂或抗与金属底材分离的性能，评定涂层通过或不通过。也可逐渐增加压陷深度，以测定涂层刚出现开裂或开始脱离底材的小深度。

　　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.

　　涂层杯突试验机依据国际标准ISO1520和**标准GB9753—88设计制造。

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

　　★试片的准备

　　（1）试片成方形，其尺寸为70mm*70mm*0.03mm~1.25mm

　　（2）试片的材质应是磨光钢板，并符合GB9271要求，试片应平整没有变形。

　　（3）试片按标准要求制备涂层，进行干燥，测量其厚度。在温度23±2°C，相对湿度50±5%的环境下，进行状态调节至少16小时后方可投入试验。

　　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涂层杯突试验机操作方法：

　　★单面涂层板的试验：——自动调零

　　将试验机手轮朝下降方向（顺时针方向）旋到底，松动试验机上部试片压紧装置，将单面涂层试板金属面朝下，涂层面朝上插入试验机上部的夹缝中，并使冲头对准该试片的**轴线，紧固压紧装置。按一下仪表红色清零按钮，显示器显示为零。以0.2±0.1mm/s（即2~3秒一圈）的速度向上升方向（逆时针方向）转动手轮。当读数到达0.40mm左右时，冲头碰到试板金属面，显示器自动显示零点，此时仪器红灯亮。再继续转动手轮，显示器读数即为上升高度，也**是压陷深度，进行中A逆转，否则读数不准。

　　★双面涂层板的试验，——手动调零

　　将试验机手轮朝下降方向（顺时针方向）旋到底，松动试验机上部试片压紧装置，用随机的调零钢板插入试验机上部的夹缝中，紧固压紧装置。按一下仪表红色按钮，使显示器显示为零。以上升方向（逆时针方向）转动手轮，当读数接近1.80mm时，放慢速度。当仪器红色灯亮时，也**是显示器为零时，停止转动手轮。松开压紧装置，再手动清零（按一下仪表红色按钮），以0.2±0.1mm/s速度向上升方向转动手轮，显示器读数为上升高度也**是压陷深度。

　　★以校正过的视力或10倍放大镜，检查试片上的涂层是否开裂或从底材上分离。

　　★上述程序应在两块单独的试片上进行，若结果不同，应补充试验，至两块试片结果一致。若底材出现裂纹，则该实验结果无效。

　　★当试片上的涂层次出现开裂，或涂层从底材上分离时，冲头停止移动（显示器上的数字为推进深度）上述试验需在同一种的底材上重复进行，以验证其结果，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.
