擺桿阻尼試驗機是檢測儀器，用于色漆，清漆及有關產品的取樣試驗，以測定色漆清漆及有關產品的皮膜硬度。擺桿阻尼試驗機根據 標準ZBN72020-86和參照標準ISO1522-1973設計制造的。

The pendulum damping tester is a testing instrument for sampling tests of paints, varnishes, and related products to determine the film hardness of paints and varnishes. The pendulum damping test machine is designed and manufactured according to the standard ZBN72020-86 and the international standard ISO1522-1973.

擺桿阻尼試驗機工作原理：

用擺桿在漆膜上擺幅衰減的阻尼時間以秒計來表示漆膜硬度是根據接觸漆膜表面的擺桿以一定周期擺時，如表面越軟的話則擺幅衰減越快，反之 越慢的原理。值得注意的是，用不同結構、質量、尺寸，周期的科尼格（Konig）和鉑鏟茲（Persoz）兩種擺桿所作的試驗結果之間沒有換算關系，這是因為擺桿與涂層間的互相作用還取決于涂層具有的復雜的彈性和粘度等原因。所以產品標準中測定某種漆膜的阻尼時間，只規(guī)定使用一種擺桿。

Working principle of pendulum damping test machine:

The damping time of the pendulum swing on the paint film is expressed in seconds. The hardness of the paint film is based on the pendulum that is in contact with the surface of the paint film at a certain period. * The slower the principle. It is worth noting that there is no conversion between the test results of Konig and Persoz pendulums with different structures, masses, sizes and cycles. This is because the pendulums are coated with The interaction between them also depends on the complex elasticity and viscosity of the coating. Therefore, the damping time of a certain paint film is determined in the product standard, and only one type of pendulum is required.

How to use the swing bar damping test machine:

★ Place the instrument base on a vibration-free workbench, and install the bottom corner screws and washers.

★ Connect the power cord of the counting device. Connect the photocell and the counting device with a connection cable.

★ Install the two control handles at the corresponding positions.

★ Place the swing lever on the positioning pin of the workbench.

★ Level the instrument base: Adjust the foot screw, observe the horizontal bubble, and correct the level.

★ Zero calibration of the pendulum: After the instrument base is calibrated horizontally, place the pendulum on the workbench and observe whether its pendulum tip is at the zero position of the scale. And then tighten the dial fastening screws.

★ Position adjustment: Adjust the photocell to 3 ° or 4 ° position.

擺桿阻尼試驗機操作規(guī)程：

★ 接通計數裝置電源，打開電源開關，將K/P擺轉換鍵置于相應位置，當實驗結束后，按動復位鍵使計數顯示復零。

★將被測試板漆膜上放置在水平工作臺上的托板上，然后轉動托板控制手柄，使擺桿慢慢落在試板上。

★轉動起動手柄拔置6°或12°處，用擺條止動裝置檔住擺條。

★ 釋放擺條止動裝置，使擺桿自由擺動，計數裝置將自動記錄下擺桿由 6°-----3°或12°-------4°的阻尼次數。其阻尼時間應按下計算：

t=T.`·n

式中：t-----涂層阻尼時間S

T-----擺的周期S/次

n-----規(guī)定角度范圍內擺桿擺動的次數。

Operating rules of pendulum damping test machine:

★ Turn on the counting device, turn on the power switch, and set the K / P pendulum switch to the corresponding position. After the experiment is over, press the reset button to reset the count display to zero.

★ Place the paint film of the board under test on the supporting board on the horizontal workbench, and then turn the supporting control handle of the board, so that the swing bar slowly falls on the testing board.

★ Rotate the starting handle to set it at 6 ° or 12 °, and use the swing bar stop device to block the swing bar.

★ Release the stop device of the swing bar to make the swing bar swing freely. The counting device will automatically record the damping times of the swing bar from 6 ° ----- 3 ° or 12 ° ------- 4 °. The damping time should be calculated as follows:

t = T.` · n

In the formula: t ----- coating damping time S

T ----- Swing period S / times

n ----- The number of swings of the swing lever within the specified angle range.

擺桿阻尼試驗機注意事項：

★準玻璃板在每次使用前應用乙醇，溶機汽油擦洗干凈。注意不得劃傷玻璃表面。

★應定期或每次試驗前，先用標準玻璃板試驗，以驗證儀器是否符合Konig擺250±10S：Persoz擺420S以上的指標，如果不符則應找出原因后排除之，使其達到要求可試驗。

★應在23±2℃相對濕度（50±5）%下進行，使用儀器時必須加上儀器罩。

★儀器不要放在光線充足的地方進行試驗，以免接光電管受外界光線影響，而使自動計數裝置不能正常計數甚至停止計數，儀器應放在無強光照射的地方。

★Konig擺的上部擺錘不要隨意改變其位置，因為該擺錘是調節(jié)K擺擺動周期之用的。改變其位置K擺的周期也將隨之改變。所以當發(fā)現K擺的周期不是1.4S時 可調節(jié)擺錘使其達到1.4S。調節(jié)方法：讓擺在玻璃板上擺動，用秒表記錄10次或20次擺動時間，看其是否是14S或28S如果不是則調整擺錘位置，再用秒表記錄其擺動時間，如此反復進行直至記錄時間達到14S或28S即擺動周期達到1.4S為止

Note on pendulum damping test machine:

★ The quasi-glass plate should be cleaned with ethanol and gasoline before use. Be careful not to scratch the glass surface.

★ It should be tested with a standard glass plate regularly or before each test to verify whether the instrument meets the specifications of Konig pendulum 250 ± 10S: Persoz pendulum above 420S. If it does not match, find out the reason and eliminate it to meet the requirements. test.

★ It should be carried out at 23 ± 2 ℃ relative humidity (50 ± 5)%, and the instrument cover must be added when using the instrument.

★ The instrument should not be placed in a place with sufficient light for testing, so as to prevent the photocell from being affected by external light, and the automatic counting device could not normally count or even stop counting. The instrument should be placed in a place without strong light.

★ Don't change the position of the upper pendulum of the Konig pendulum at will, because the pendulum is used to adjust the swing period of the K pendulum. The period of changing its position K pendulum will also change accordingly. So when it is found that the period of the K pendulum is not 1.4S. Adjustable pendulum to 1.4S. Adjustment method: swing the pendulum on a glass plate, record the swing time 10 or 20 times with a stopwatch, and see if it is 14S or 28S. If it is not, adjust the position of the pendulum, and then record the swing time with a stopwatch. When the time reaches 14S or 28S, the swing period reaches 1.4S.
