摇杆漆膜强度测试仪操作程序

八戒

The SOP is written for the hardness rocker and leveling table currently used , and limited to Sheen 703/704。

本程序仅针对Sheen 703/704型号摇杆漆膜强度测试仪正确使用的操作。


PROCEDURE操作程序

The leveling table with the test plates is leveled carefully and the surface of the glass test plate thoroughly cleaned. The underside rings of the rocker should be examined critically and cleaned with a suitable solvent to remove any sticky deposits.
小心放置带有测试盘的水平台在水平位置，玻璃测试盘擦洗通彻干净。下侧的摇杆环应严格检查并用适当的溶剂擦洗干净。

1.
Place the rocker carefully onto the test surface , roll the instrument to the right until bubbles are in view. Ensure that no undue pressure is applied to the rocker.
小心放置摇杆于测试漆膜表面，向右方向滚动设备直至看见泡沫。确定无不适当的压力使用于摇杆。

2.
Release the rocker START counting the number of “rocks” (complete oscillations) when the LEFT-HAND bubbles just disappears.
当LEFT-HAND泡沫刚消失时，释放摇杆开始计算摇摆的次数（完全摆动）。

3.
STOP the count when the right-hand bubble just dispears.
当RIGHT-HAND泡沫刚消失时停止计数.

4.
The rocker is set before despatch to make 50 oscillations on a standard glass plate with the period of oscillation being set at 60±0.5 seconds by means of the adjustable knurled nuts .A frequent check should be made on the number of oscillations the apparatus makes on the standard glass plate.
摇杆使用前应在标准玻璃盘上依靠可调节滚花螺母60±0.5秒内完成50次摆动。应经常放置在标准玻璃盘上检查摆动次数的显示正确。

5.
It is usual to express the results obtained from the test piece as a percentage of the number of rocks made on the plate glass standard representing 100%.
通常做法以在标准玻璃盘上的测试数为100％，样板测试数据为对应摇摆数的百分比。

6.
The change of state for rocker hardness can be monitored against time provided that the coating is smooth, free from blemishes, and its thickness controlled.

摇杆的使用状态是受漆膜光滑程度，污点，控制的漆膜厚度所影响的。
