技术领域Technical field
本发明属于电力设备检测技术领域，具体涉及一种检测输变电钢构架热镀锌层色差质量方法。The invention belongs to the technical field of electric equipment detection, and specifically relates to a method for detecting the color difference quality of hot-dip galvanized layers of power transmission and transformation steel frames.
背景技术Background technique
热浸镀技术是一种将要浸镀的基材浸入熔化的涂层金属或合金液中，保持基体表面与熔融金属接触一段时间后取出，使之粘附一层均匀的、表面光洁的，与基体牢固结合的金属防腐镀层的保护方法。现行国标以及行标检测项目均为镀锌层外观、厚度、均匀性及附着力四个方面。外观主要采用目视检查，要求表面连续、完整，不得有酸洗、漏镀、结瘤、积锌、毛刺等缺陷，镀锌颜色一般呈灰色或暗灰色。针对外观颜色，标准未给定色差具体评价值，全凭验收人员的目视以及经验，造成验收评价标准不一，部分钢构架热镀锌层颜色深浅不一致，存在明显色差，严重影响工程整体观感，甚至影响工程参与鲁班奖等建筑类评奖结果。因此，开展输变电钢构架热镀锌层色差评定，显得尤为重要。Hot dip plating technology is a method of immersing the substrate to be dip-plated into molten coating metal or alloy liquid, keeping the surface of the substrate in contact with the molten metal for a period of time and then taking it out, so that a uniform layer of coating with smooth surface can be adhered to it. A method of protecting metal anti-corrosion coatings that are firmly bonded to the substrate. The current national standard and industry standard testing items are all four aspects of galvanized layer appearance, thickness, uniformity and adhesion. The appearance is mainly visually inspected. The surface is required to be continuous and complete, and there must be no defects such as pickling, missing plating, nodules, zinc accumulation, burrs, etc. The color of galvanizing is generally gray or dark gray. Regarding the appearance color, the standard does not provide a specific evaluation value of color difference. It all depends on the visual inspection and experience of the acceptance personnel, resulting in different acceptance evaluation standards. The color of the hot-dip galvanized layer of some steel structures is inconsistent and there is obvious color difference, which seriously affects the overall look and feel of the project. , and even affects the results of the project's participation in architectural awards such as the Luban Award. Therefore, it is particularly important to carry out color difference assessment of hot-dip galvanized layers of power transmission and transformation steel structures.
任何颜色都是由红、绿、蓝三基色组成，定量地表示两个刺激色样之间的颜色差异程度的量值为色差。其计算公式为：Any color is composed of three primary colors: red, green, and blue. The value that quantitatively expresses the degree of color difference between two stimulus color samples is color difference. The calculation formula is:
ΔE1=；ΔE1 = ;
其中：ΔL为明度差；Δa为红黑色品差；Δb为蓝黄色品差。Among them: ΔL is the brightness difference; Δa is the quality difference between red and black; Δb is the quality difference between blue and yellow.
而人眼做为图像的接受终端，外界光线通过角膜、虹膜、晶状体聚焦在视网膜上，刺激感光细胞发出神经脉冲，经视神经传递到大脑产生视觉。人眼分辨力与亮度和灰度有关。亮度分辨力是指对亮度的微小变化的判别能力，以人眼能分辨的最小亮度差ΔL与亮度之比来表示。灰度用黑色为基准色，不同的饱和度的黑色来显示图像。每个灰度对象都具有从0%到100%的亮度值，百分比越高，颜色越偏黑，百分比越低，颜色越偏白。将白色与黑色之间按照对数关系分成若干级，成为灰度等级，范围0～255，白色为255，黑色为0。The human eye serves as the receiving terminal for images. External light is focused on the retina through the cornea, iris, and lens, stimulating photoreceptor cells to emit nerve impulses that are transmitted to the brain through the optic nerve to produce vision. Human eye resolution is related to brightness and grayscale. Brightness resolution refers to the ability to distinguish small changes in brightness, expressed as the ratio of the minimum brightness difference ΔL that the human eye can distinguish to the brightness. Grayscale uses black as the base color and displays images with different saturations of black. Each grayscale object has a brightness value from 0% to 100%, with higher percentages making the color darker and lower percentages making the color whiter. The relationship between white and black is divided into several levels according to the logarithmic relationship, which becomes the gray scale, ranging from 0 to 255, with white being 255 and black being 0.
据资料表明，在0～255灰度显示系统中，灰度级数为8、16、32时人眼正确识别率分别为93.16%、68.75%、45.31%。因此，当两物体色差值为8及以下时，人眼分辨较困难。According to data, in a 0 to 255 grayscale display system, when the grayscale levels are 8, 16, and 32, the correct recognition rates of the human eye are 93.16%, 68.75%, and 45.31% respectively. Therefore, when the color difference value of two objects is 8 and below, it is difficult for the human eye to distinguish.
