数显漆膜摆式硬度计工作原理

有一定重量和形状的摆,接触于被测皮膜的表面,由于重力摆和涂层间的相互作用是复杂的弹性和粘弹性的两种性质,且又因摆的重量、形状以及地理和环境等因素的影响,因此,表面愈软,接触于这一表面的重力摆的摆幅衰减愈快。

皮膜硬度的表示是以一定重量的摆,置于标准玻璃上,在规定的角度范围内所摆动的振幅时间或次数和置于被测皮膜上,在规定的角度范围内所摆动的在振幅时间或次数之比表示之,

即: H=n/n0

式中:n:摆在皮膜上,在规定的角度范围内所摆动的振幅时间或次数。

n0:摆在玻璃板上,在规定的角度范围内所摆动的振幅时间或次数。

Paint film pendulum hardness tester works:
A pendulum with a certain weight and shape, which is in contact with the surface of the film to be tested, because the interaction between the gravity pendulum and the coating is a complex elastic and viscoelastic property, and because of the weight, shape, geography and environment of the pendulum The influence of other factors, therefore, the softer the surface, the faster the swing of the gravity pendulum touching the surface decays.
The hardness of the film is expressed by the pendulum of a certain weight, placed on the standard glass, the amplitude of the amplitude or the number of times of swinging within a specified angle range, and the amplitude of the time that is placed on the film to be tested and oscillated within a specified angle range. Or the ratio of times,
Ie: H=n/n0
Where: n: amplitude time or number of times of swinging on the film over a specified range of angles.
N0: amplitude time or number of times of swinging on a glass plate within a specified range of angles.

数显漆膜摆式硬度计操作与使用

★从附件箱里拿出地角调整螺钉垫片,放入仪器外罩内,把主机放置其上,调整地角螺钉,观看水平泡,把主机调整并置于水平位置。

★把电源插头线盒光电头线分别插于计数器后面的各自插座上。把光电头线另一端的U型支架放在标尺后面的U型支架固定槽内,并用相应的螺钉紧固。光电头所放的位置应在标尺刻度线2°内侧之切线位置处。

★把摆从附件箱里取出来,置于工作台和标准玻璃板上,扳起定位提手,把摆之横梁上的缺口对准定位提手的刀口,摆静止后,应对准标尺刻度的另点,如不在另点则应水平移动标尺,然后用支柱上的螺钉紧固住。

★启动摆条推动机构、止动机构,使摆条置于5°的正视线上,扳下定位提手。

★接通计算器电源,启动计数器电源开关,推动止动装置使摆条自由摆动(注意摆条支点不要移动)摆条在标准玻璃上摆动的时间为440S±6S,次数为352±4次。若不在此时间或次数内则应调整摆上的微调捶,反复微调,使其达到上述标准值。

★把所测涂料用涂膜涂布器或其它方法均匀地涂布在试验用玻璃板上。

★涂膜的干燥(自干或烘干)应达到产品要求所规定的时间。

★漆膜的厚度应达到产品所规定的标准。

★把制备好的漆膜试验板放置在工作台上,观其摆从2°~5°摆动所用的时间和次数,并将其秒数,或次数记录下来。

★用工作原理一节中所提供的公式计算之,所得之数即为所测漆膜硬度值,一般在一块试片上(不同位置)作三次试验,将所得的结果求取算术平均值为A后结果,但两次所测得之差,不得大于3%(秒数)度数不得大于5% 。

★每次试验前应用、乙醇或溶机汽油将标准玻璃板或摆条上的钢珠擦拭干净,擦拭所用之抹布应清洁,不要把标准玻璃板造成划痕。

★支点钢珠应定期检查,当发现有钢珠表面损伤时,可稍微移动钢珠,变换它的接触点,钢珠表面如磨至不符合要求时,则应更换新钢珠。

★应当指出:本仪器反映了涂料对其环境的敏感性,因而试验应当在25±1°C,相对湿度60%~70%,周围无振动的条件下,且在无气流的条件下进行之。因此,试验时必须加外罩并关闭所有小门

Paint film pendulum hardness tester operation and use:
★ Take the corner adjustment screw gasket from the accessory box, put it into the instrument cover, place the main unit on it, adjust the corner screw, watch the horizontal bubble, and adjust the main unit to the horizontal position.
★ Insert the power plug wire box photoelectric head wires into the respective sockets on the back of the counter. Place the U-bracket on the other end of the photoelectric head wire in the U-bracket fixing groove behind the ruler and fasten it with the corresponding screws. The position of the photocell should be placed at the tangent position inside the 2° of the scale line.
★ Take the pendulum out of the accessory box, place it on the workbench and the standard glass plate, erect the positioning handle, align the notch on the beam of the pendulum with the edge of the handle. After the pendulum is stationary, it should be aligned with the scale. In addition, if it is not at another point, the ruler should be moved horizontally and then fastened with the screws on the pillars.
★ Start the swinging pushing mechanism and the stopping mechanism, so that the pendulum bar is placed on the front line of 5°, and the positioning handle is pulled down.
★ Turn on the calculator power, start the counter power switch, push the stop device to make the pendulum swing freely (note that the pendulum support point does not move). The pendulum swings on the standard glass for 440S±6S, the number of times is 352±4 times. If it is not within this time or number of times, the fine adjustment 摆 on the pendulum should be adjusted and fine-tuned repeatedly to reach the above standard value.

★ The test coating is uniformly applied to the test glass plate by a coater or other method.
★ The drying (drying or drying) of the coating film should meet the time specified in the product requirements.
★The thickness of the paint film should meet the standards stipulated by the product.
★ Place the prepared paint film test board on the workbench and observe the time and number of times it takes to swing from 2° to 5°, and record the number of seconds or times.
★ Calculated by the formula provided in the working principle section, the obtained number is the hardness value of the measured paint film. Generally, three tests are performed on one test piece (different positions), and the obtained result is obtained as the arithmetic mean value A. After the result, but the difference measured twice, no more than 3% (seconds) degree should not exceed 5%.
★ Wipe the standard glass plate or the steel ball on the pendulum strip before application, ethanol or machine gasoline. The rag should be cleaned and the standard glass plate should not be scratched.
★The fulcrum steel ball should be inspected regularly. When the surface of the steel ball is found to be damaged, the steel ball can be slightly moved to change its contact point. If the surface of the steel ball is not suitable for grinding, the new steel ball should be replaced.
★ It should be pointed out that: This instrument reflects the sensitivity of the coating to its environment, so the test should be carried out at 25±1°C, relative humidity 60%~70%, without vibration around, and without air flow. . Therefore, it is necessary to add a cover and close all the small doors during the test.
