    厂家传授测量环氧地坪漆硬度的方法

    2019-03-30 21:26:12 无锡盛发地坪科技竞彩足球 阅读

    测量环氧地坪漆的硬度需要使用到一组中华高级绘图铅笔,铅笔硬度有6B,5B,4B,3B,2B,B,HB,F,H,1H,2H,3H,4H,5H,6H,7H,8H,9H共17种。从6B到9H,铅笔硬度逐渐增大。测量环氧地坪漆的硬度主要有两种方法:使用铅笔硬度计测量和试验机法。

    To measure the hardness of epoxy floor paint, a set of Chinese advanced drawing pencils are used. The pencil hardness is 6B, 5B, 4B, 3B, 2B, B, HB, F, H, 1H, 2H, 3H, 4H, 5H, 6H, 7H, 8H and 9H, totally 17 kinds. From 6B to 9H, the hardness of pencil increases gradually. There are two main methods to measure the hardness of epoxy floor paint: pencil hardness tester and testing machine. 

    一。使用铅笔硬度计测量

    I. Measurement with Pencil Hardness Meter

    1、将硬度计平放在试片上(如果试验片比硬度计小,请将试验片放在硬度计前面并且把垫片放置于硬度计前端下方,目的是使硬度计保持水平。

    1。 Place the hardness tester flat on the test piece (if the test piece is smaller than the hardness tester, please put the test piece in front of the hardness tester and place the gasket below the front end of the hardness tester in order to keep the hardness tester level。

    2、用刀片削开铅笔笔芯,使铅笔芯凸出部分约为3~5mm,并用砂纸磨平,再将铅笔插入仪器,使笔芯与试验片接触后并固定锁紧,(建议:铅笔为六边形,固定时选择一个平面,测试后,旋转两个平面再固定测试,再旋转两个平面固定测试,一个圆周面可使用三次)试验时要将垫片移开。

    2。 Cut pencil lead with blade, make the protruding part of pencil lead about 3-5mm, grind it flat with sandpaper, insert pencil into instrument, make pencil lead contact with test piece and fix and lock it。 (Suggestion: pencil is hexagonal, choose a plane when fixing, rotate two planes after testing, then fix the test, rotate two planes to fix the test, one circumference can be used three times) The gasket should be removed in time。

    3、用拇指与中指抓在两个轮子的中心。将硬度计从后往前推进约2cm-3cm即可移开硬度计,再用橡皮将划过的铅笔擦掉。(推硬度计时请勿加任何压力)

    3。 Grab the center of two wheels with thumb and middle finger。 Push the hardness tester back and forth about 2cm-3cm to remove the hardness tester and erase the pencil with a rubber。 (Push hardness time without any pressure)

    4、判别硬度,看试片有无刮痕。建议试片最少做三个位置以上,取平均值。硬度级数从软到硬分别为:6B、5B、4B、3B、2B、B、HB、F、H、2H、3H、4H、5H、6H、7H、8H、9H,共17种。例如:使用H铅笔表面无刮痕,使用2H铅笔表面也无刮痕 ,使用3H铅笔表面有刮痕,所以试验片涂装硬度级数为:2H 。

    4。 Discriminate the hardness and see if there are scratches on the test piece。 It is suggested that the test pieces should be made at least three locations and the average value should be taken。 Hardness series from soft to hard are 6B, 5B, 4B, 3B, 2B, B, HB, F, H, 2H, 3H, 4H, 5H, 6H, 7H, 8H, 9H, totally 17 kinds。 For example, there are no scratches on the surface of H pencil, 2H pencil and 3H pencil, so the hardness of the test piece is 2H。


    二.试验机法

    II。 Testing Machine Method

    a、铅笔处理。削去铅笔木杆,使铅芯露出3mm,铅笔与砂纸垂直,在砂纸上打圈摩擦,使其端面平整,边缘清晰锐利。

    A. Pencil processing. Cut the pencil rod to expose the lead core 3 mm. The pencil is perpendicular to the sandpaper and rubs in a circle on the sandpaper to make the end face flat and the edge clear and sharp.

    b、固定试件。将环氧地坪漆试件放置在试验机的试件放置台上,固定。

    B. Fixed specimens. Place the floor paint test piece on the test machine and fix it.

    c、调节铅笔。从6B开始,将铅笔放置在铅笔夹具内,铅笔笔尖处于试验机重物重心垂直线与漆试件的交点处,拧紧夹具。

    C。 Adjust pencils。 Starting from 6B, the pencil is placed in the pencil fixture。 The pencil tip is at the intersection of the vertical line of gravity center of gravity of the test machine and the test piece of floor paint。 The fixture is tightened。

    d、调节平衡重锺。调节地坪漆试验机左侧的平衡重锤,使铅笔笔尖接触地坪漆试件,但对其压力为零,拧紧固定螺丝。

    D. Adjusting the balance weight. Adjust the balance weight on the left side of the floor paint tester so that the pencil tip touches the floor paint specimen, but the pressure is zero, tighten the fixing screw.

    e、放置重物。放置1KG的重物,放松固定螺丝。

    E. Place heavy objects. Place 1KG weight and loosen the fixing screw.

    f、测试。恒速摇动手轮,使地坪漆试件以0.5mm/s的速度逆笔芯方向移动。每一硬度标号的铅笔划刮5次,每划一笔都需重新打磨铅笔。

    F. Testing. The hand wheel is shaken at constant speed, so that the floor paint specimen moves in the direction of the pen core at a speed of 0.5mm/s. Each hardness marking pencil scratches five times, and each stroke needs to be re-polished pencil.

    g、察看擦刮结果。若有两道或者两道以上漆膜没有被划伤,则换下一位硬度更高的铅笔,重复上面的步骤。若5道划痕中有两道或两道以上划伤漆膜,则以上一硬度标号为该地坪漆漆膜硬度。

    G. Check the scraping results. If two or more coatings have not been scratched, replace a pencil with a higher hardness and repeat the steps above. If there are two or more scratches in the five scratches, the above hardness label is the hardness of the floor paint film.
