漆膜划痕仪根据GB9279《色漆和清漆 划痕试验》和ISO 12137-2《色漆和清漆 耐划伤性的测定》中有关规定而精心设计制造的。本测试仪是用来测定色漆和清漆的单一涂层或复合涂层体系或水性木漆在标准条件下的耐划透和耐划伤性。本仪器采用大速比大输出扭矩齿轮减速箱,以保证在不同测试负载下划针移动速度恒定,使测试结果具有较高的精度。

The paint film automatic scratch tester is designed and manufactured according to the relevant provisions of GB9279 “Scratch test for paints and varnishes” and ISO 12137-2 “Determination of scratch resistance of paints and varnishes”. This tester is used to determine the scratch resistance and scratch resistance of single or composite coating systems or waterborne wood lacquers for paints and varnishes under standard conditions. The instrument adopts a large speed ratio large output torque gear reducer to ensure that the needle movement speed is constant under different test loads, so that the test results have higher precision.

 

漆膜划痕仪目前可以做的是两种底材的试验。一种是测试色漆和清漆水性木漆的涂层耐划透性,底材是金属,漆膜是否被划透可以通过仪器上的电压表的指示而直观的得到结果,另一种是测试水性木漆的耐划伤性,底材是木材,漆膜是否被划伤是通过肉眼或放大镜的观察得出结果的。

The paint film automatic scratch tester can currently do the test of two kinds of substrates. One is to test the scratch resistance of the paint of the paint and varnish water-based wood paint. The substrate is metal. Whether the paint film is scratched or not can be intuitively obtained by the indication of the voltmeter on the instrument. The other is the test. The scratch resistance of water-based wood lacquer, the substrate is wood, and whether the paint film is scratched is the result of observation by naked eye or magnifying glass.

漆膜划痕仪操作规程

★试板的准备:

a.材料和尺寸:除另有规定或商定外,试板底材的尺寸应为150×70mm的长方形,并满足 GB9271规定的马口铁板,薄钢板和硬铝板。如果待测试样品要求刷涂,则所用底材的尺寸应略大些,刷纹应平行于板的短边,干燥后并能在试板短边一向切割出150×70mm的试板。水性木漆的底材则是木材。

b.试板的处理和施涂:除另有规定或商定外,应按GB9271进行,然后按规定方法施涂待测试样品。

c.试板的干燥:除另有规定外,试板应按受试产品的规定进行干燥。然后试板应在温度(23±2)℃、相对湿度(50±5)%的条件下,至少干燥16小时后在进行试验。

★环境温度:除另有规定外,试验应在(23±2)℃和(50±5)%相对湿度下进行。

Paint film automatic scratch tester operating procedures:
★ Preparation of test panels:
a. Materials and Dimensions: Unless otherwise specified or agreed, the size of the test board substrate shall be 150 × 70 mm rectangular, and meet the requirements of GB9271 for tinplate, thin steel and hard aluminum. If the sample to be tested requires brushing, the size of the substrate used should be slightly larger. The brush pattern should be parallel to the short side of the plate. After drying, the 150×70 mm test plate can be cut out on the short side of the test plate. The substrate for waterborne wood lacquer is wood.
b. Treatment and application of test panels: Unless otherwise specified or agreed, it shall be carried out in accordance with GB9271, and then the samples to be tested shall be applied in accordance with the prescribed methods.
c. Drying of test panels: Unless otherwise specified, the test panels shall be dried as specified in the test product. The test panel shall then be tested at a temperature of (23 ± 2) ° C and a relative humidity (50 ± 5)% for at least 16 hours.
★ Ambient temperature: Unless otherwise specified, the test shall be carried out at (23 ± 2) °C and (50 ± 5)% relative humidity.

 

漆膜划痕仪操作方法:

★将本仪器放在稳固、平坦的试验台上,操作者正对仪器。

★取下划针,用放大镜观察划针的针头应是光滑的半球状,无明显的磨伤且无污物的,否则应更换新的划针。划针与导向柱安装高度可以根据试板的厚度来调整。

★旋开左端试样夹具上的紧定螺栓,放入固定板下,试板的涂层向上,然后旋紧紧定螺栓。

★将电源插头插入位于墙壁上的电源插座,并打开电源开关。

★下面的操作需要对两块试板各做三次试验:

a.固定负荷的通过/不通过试验:在砝码支架上放上所需要的砝码。按下仪器上的“划痕”按扭。如果电压表在划痕的过程中有指示,则证明漆膜被划透。

b.测定划透涂层的A小负荷试验:先开始用较小负荷,然后逐渐以适当增量逐渐增加负荷直到涂层被划透为止。在该试板的未划部分和另一块新试板上用该负荷重复试验,所得结果相符之后,记下A小负荷值。

★旋动仪器右边的抬针螺栓,取下试板观察。

★按下“复位”按钮,则划针回到原位,即可开始下一次划痕。

Paint film automatic scratch tester operation method:
★ Place the instrument on a stable, flat test bench with the operator facing the instrument.
★ Remove the needle and use a magnifying glass to observe the needle. The needle should be smooth and hemispherical. There is no obvious abrasion and no dirt. Otherwise, a new needle should be replaced. The height of the stylus and guide post can be adjusted according to the thickness of the test plate.
★ Unscrew the tightening bolt on the left end of the specimen holder, place it under the fixing plate, and coat the coating plate upwards, then tighten the tightening bolts.
★ Plug the power plug into a wall outlet and turn on the power switch.
★ The following operations require three tests on each of the two test panels:
a. Pass/fail test of fixed load: Put the required weight on the weight bracket. Press the “scratch” button on the instrument. If the voltmeter indicates during the scratching process, the paint film is smeared.
b. Determination of the A-small load test of the scratch-through coating: first start with a small load and then gradually increase the load gradually in the appropriate increments until the coating is scratched. The test was repeated with the load on the unlined portion of the test plate and another new test plate, and after the results were obtained, the A small load value was recorded.
★ Turn the needle on the right side of the instrument and remove the test plate to observe.
★Press the “Reset” button and the needle will return to the original position to start the next scratch.

 

漆膜划痕仪主要结构:

利用一恒速马达,通过齿轮齿条传动带动划针滑动,划针垂直于漆膜。划针顶端是一直径为1mm的硬质钢的半球形针头。上方有支架,支架上可以根据需要放置50g到2000g的砝码。支架的后部有一用来平衡支架自动的平衡块。砝码支架的转轴采用滚珠轴承支承,转动灵活,减小了磨擦力矩,从而使施加在金刚石划针尖端的压力具有良好的重复性,也即保证了测试结果具有良好的重复性。仪器上设有用来夹紧试板的夹紧机构。支架的后部设有在划针复位的时候用来抬起划针的抬针螺栓。机器的面板上有一电压表,当样板上的漆膜被划针划透时,电压表即有指示,这样可以确定的判断漆膜是否被划透,消除了人为误差。

The main structure of the paint film automatic scratch tester:
Using a constant speed motor, the needle is driven by the rack and pinion drive, and the needle is perpendicular to the paint film. The tip of the stylus is a hemispherical needle of hard steel having a diameter of 1 mm. There is a bracket on the top, and a weight of 50g to 2000g can be placed on the bracket as needed. At the rear of the bracket there is a balancing weight that is used to balance the bracket automatically. The shaft of the weight bracket is supported by ball bearings, which makes the rotation flexible and reduces the friction torque, so that the pressure applied to the tip of the diamond needle has good repeatability, that is, the test result has good repeatability. The instrument is provided with a clamping mechanism for clamping the test plate. The rear part of the bracket is provided with a lifting bolt for lifting the stylus when the stylus is reset. There is a voltmeter on the panel of the machine. When the paint film on the sample plate is scratched by the stylus, the voltmeter has an indication, so that it can be determined whether the paint film is scratched or not, and the human error is eliminated.

 

漆膜划痕仪注意事项:

★如果是测定水性木漆得耐划伤性试验,由于底材是木材,所以电压表无指示。划痕后取下试板观察试板是否被划伤。根据需要可以使用适当倍数的放大镜,但应在试验报告中注明放大倍数。

★机器支架上的平衡块是用来平衡支架的自重,机器出厂时已经通过调整确定了位置,请不要轻易松开平衡块上的螺丝,以免影响测试的准确性。

★待所有试验结束后,取下砝码,并放回原处,盖好包装木盒盒盖,以保护本仪器的清洁。

Paint film automatic scratch test notes:
★ If it is a test for the scratch resistance of waterborne wood lacquer, since the substrate is wood, the voltmeter has no indication. After the scratches, remove the test plate and observe whether the test plate is scratched. A magnifying glass of the appropriate multiple can be used as needed, but the magnification should be indicated in the test report.
★The balance block on the machine bracket is used to balance the weight of the bracket. The machine has been adjusted to determine the position when it leaves the factory. Please do not loosen the screws on the balance block to avoid affecting the accuracy of the test.
★ After all the tests are finished, remove the weight and put it back in place, and cover the wooden box cover to protect the instrument.
