、 400水砂纸、 铅笔硬度测试仪;Preparation: 2B Zhonghua brand drawing pencil, Great Wall brand drawing eraser, pencil sharpener, water abrasive paper and pencil hardness tester. b. 试用铅笔的备制,用削笔刀削去木杆部分,使笔芯呈圆柱状露出约 3mm。 然后 在坚硬的平面上 放置砂纸,将铅芯垂直靠在砂纸 上划圆圈,慢慢地研磨,直至铅笔尖端磨成平面,边缘锋利成止。 Prepare a pencil and cut the wood part so that the pencil lead exposed about 3mm. And then place the abrasive paper on a hard flat surface and draw cycle against it vertically, grinding slowly, until the pencil tip bees a flat, sharp edge. c. 将待测试件 水平放置,且 固定在铅笔硬度测试仪上,待测试面朝上。 Place the specimens horizontally and fix them on the pencil hardness tester, the test surface up. d. 试验机的重物通过重心的垂直使待测试面 (涂膜 )的交点接触到铅笔芯的尖端,将铅笔固定在铅笔夹具上。 The tester heavy weight makes the connecting rod of test surface (coating) contact the pencil lead tip and is fixed on the tong through the uprightness of center of gravity. e. 调节 平衡 重 锤,使 测试样板上的加载的铅笔负荷处于不正不负的状态,然后将固定螺丝拧紧,使铅笔离开测试面,固定连杆,在重物放置台上加上 177。 的重物,放松固定螺丝,使铅笔芯的尖端接触到待测面,重物的负荷加到笔芯的尖端上 ,笔尖与测试面呈 45 度角。 Adjust the balance weight so that the pencil load added on the specimens is in a state of 0 and then tighten the screw so that the pencil to leave the test surface, fix the lever, add 177。 kg of weight and relax the fixed screw so that the pencil lead tip can contact the test surface, the heavy load is added on the pencil lead tip, the tip and the test surface is 45degree angle. f. 开启测试仪电源开关, 调节工作行程为: 5mm,使铅笔芯来回刮划测试面,移动速度为 ,将测试件向着与移动方向垂直的方向挪动,以变 动 位置,刮划五道。 铅笔的尖端,每道刮划后,要重新磨平后再用。 Open the tester power switch to adjust the rubbing trip to 5mm so that the pencil lead can scratch the test surface back and forth at a speed of / s. Remove the test units perpendicularly to the movement direction so as to change the location and scratch 5 traces. The pencil tip should be rubbed down again to reuse after scratching. d. 接收标准: (本公司适用 ) Acceptable standard ( applicable to the pany) ★对于本 公司所属产品,适用测试的 2B 铅笔 刮划 五道刮痕 后 , 确认测试 表面 涂膜(镀层) 状态,刮破或刮伤小于等于两道刮破或刮伤印痕的状况,判定 OK; For the Companyowned products, confirm the condition of the coating surface (plating) after scratching 5 traces with 2B pencil. If equal to or less than 2 traces, it’s consider to be ok. ★表面 涂膜(镀层) 刮破或刮伤等于三道或三道以上刮破或刮伤印痕的状况,判定 NG; The coating surface (plating) of the test products scratched 3 or more than 3 traces: NG. 防酒精测试: Antialcohol test a.。
