在粉末涂料行业获得正确颜色的技巧

Posted on Jan 29, 2026 by HunterLab

粉末涂装是一种干式表面处理工艺,能够提升效率、最大化产量并增强环保合规性。该涂层提供几乎无限的色彩选择,因此选择何种颜色可能令人难以抉择。了解更多关于如何挑选粉末涂料颜色的信息。

什么是粉末涂层?

粉末涂料是由固化剂、流动改性剂和流平剂组成的干粉。该混合物通过静电喷涂沉积(ESD)技术和喷枪施加于表面。静电荷促使粉末颗粒附着于表面并形成结合。粉末涂料涂覆后需经热固化处理。

这种耐用的涂层能保护表面免受锈蚀、腐蚀及自然环境的影响。它也可作为装饰性涂层,为设备增添特定色彩。

粉末涂料行业实现色彩精准的秘诀

为设备选择合适的外观可能颇具挑战,毕竟可选方案实在太多。若您翻阅粉末涂料色卡仍难以抉择,不妨参考以下挑选粉末涂料颜色的建议:

  • 在不同光照条件下观察: 光线会影响我们对颜色的感知。请在阳光下、阴影处和荧光灯下分别查看粉末涂料样本,并调整光源角度。这些不同的观察条件将帮助您清晰了解粉末涂料的实际呈现效果。
  • 确定配色方案:若仅对设备某部分进行粉末喷涂,可选择点缀色使其更显亮眼,选用对比色突出视觉效果,或采用互补色以契合整体外观。
  • 隐藏零件瑕疵:深色与金属色粉末涂层最能遮盖零件表面的瑕疵。
  • 选择半光或缎光涂层:半光或缎光粉末涂层能提供恰到好处的反射效果,使部件外观美观。在某些条件下,高光涂层可能过于闪亮。
  • 打造工业风:若想让物件呈现粗犷或商业风格,哑光与平光饰面是最佳选择。

Tips to Getting Color Right in the Powder Coating Industry

Posted on Jan 23, 2026 by HunterLab

Powder coating is a dry finishing process that can improve efficiency, maximize production, and enhance environmental compliance. This coating is available in virtually limitless color options, so it can be hard to know what color to use. Read more about how to pick a powder coat color.

What Is Powder Coating?

Powder coating is a dry powder made from curatives, flow modifiers, and leveling agents. This mixture is applied to the surface using electrostatic spray deposition (ESD) and a spray gun. The electrostatic charge helps attract the powder particles to the surface, creating a bond. Once the powder coating is applied, it is cured with heat.

This durable finish protects the surface from rust, corrosion, and exposure to the elements. It can also be used as a decorative finish to give the equipment a certain color.

Tips to Get Color Right in the Powder Coating Industry

Getting the right look for your equipment can be challenging since there are so many options available. If you’re looking at a powder coating color chart and still cannot decide which color to go with, follow these tips for picking a powder coat color:

  • Get in different lighting: Light influences how we perceive color. View your powder coating sample in the sunlight, a shadowed space, and fluorescent light, and put the light source at different angles. These different viewing conditions will give you a good picture of what the powder coating will look like.
  • Decide on a color style: If you are powder coating just one part of your equipment, you can choose an accent color to make it pop, a contrasting color to stand out, or a complementary color to fit the look.
  • Hide the part’s imperfections: Dark and metallic powder coating colors best hide imperfections on the part’s surface.
  • Choose a semi-gloss or satin finish: A semi-gloss or satin powder coating finish gives you the right amount of reflection to make the part look nice. A glossy finish can be too shiny in some conditions.
  • Go for an industrial look: Matte and flat finishes are the best choices if you want a tough or commercial look for the piece.

What are Hydrochromic or Hygrochromic Color Samples?

Posted on Jan 23, 2026 by HunterLab

"hydro"源自希腊语"水","hygro"源自希腊语"hygrós"(意为湿润或潮湿),这两个词常用于描述同一光学现象的两种表述。

ASTM E284标准外观术语规范中更倾向于使用“湿变色”这一名称。

How can I use EasyMatch QC to measure Contrast Ratio Opacity?

Posted on Jan 23, 2026 by HunterLab

对比度比值不透明度测量通过两次读数量化样片的不透明程度。首次读数时,样片在测量端口处需以黑色玻璃或遮光板为背衬;第二次读数时,则需以白色瓷砖或白色样片夹具衬板为背衬。进行不透明度测量时,EasyMatch QC将提示您选用正确的背衬材料。

EasyMatch QC中的不透明度测量

要在EasyMatch QC中执行不透明度测量,首先需以反射率模式对仪器进行标准化。完成反射率标准化后,通过选择“选项/读取方法”路径,在颜色数据视图中选取“不透明度”进行显示。

将打开一个新窗口,允许您选择"对比度比透明度"作为阅读模式。其他显示选项包括:

  • Y 样品背衬白色底板后的亮度值,可作为附加光学信息用于指示整体反射率或发光亮度。
  • Y 样本在黑色衬底上的亮度值,该值是对比度比不透明度计算的第二个组成部分。

典型的显示效果仅为不透明度,部分用户会选择不透明度与Yw值的组合。

另一种选择是为不透明度报告选择光源和观察者。若无预设条件,请选择C/2。完成所有选项后点击“确定”保存,这些指标将显示在您的颜色数据视图中。

将鼠标悬停在颜色数据视图上/右键点击/选择配置,即可选取额外指标,例如作为完整色彩量化指标的CIE L*、a*、b* D65/10色值,或作为白色材料黄度单一量化指标的黄度指数E313 C/2或D65/10。不同指标提供不同的光学信息。 色值用于量化薄膜的色彩属性;对比度不透明度则量化薄膜材料的遮蔽程度。

Contrast Ratio Opacity

Posted on Jan 22, 2026 by HunterLab

在工业和商业产品中使用时,作为光学特性的“不透明度”具有多种定义。

对比度透光率(OP)测量值量化了近不透明材料接近不透明的程度。

该测量方法采用两部分程序指标:首先在黑色背景衬托下测量样品的CIE Y值(即亮度值),随后在白色背景衬托下再次测量样品的Y值。所得比值以Y%表示,计算公式如下:

Y值亮度是基于CIE光源/观察者计算得出的比色值。

在特定条件下,必须明确指定并报告光源/观测者选择。不同行业会采用不同的光源/观测者组合——A/2(汽车行业)、C/2(历史标准及默认选择)、D65/2(印刷行业)以及D65/10(当前色彩测量中常用)。由于不透明度是比率值,在任何光源/观测者条件下,测量结果都将近乎一致。

在涂层涂布样片以及纸张、塑料和纺织品的单张或单层材料中,对比度不透明度作为关键外观特性具有典型应用价值。
对于本质上不完全不透明的材料,首要外观考量在于批次间的一致性。

How can I use EasyMatch QC to measure Contrast Ratio Opacity?

Posted on Dec 18, 2025 by HunterLab

Contrast Ratio Opacity measurement quantifies how opaque a sheet sample using two readings. One reading is taken with the black glass or light trap backing the sample at the port. The second reading is taken with the sample backed by a white tile or the white sample clamp insert. EasyMatch QC will prompt you for the proper backing when taking opacity measurements.

Opacity Measurement in EasyMatch QC

To perform opacity measurements in EasyMatch QC, first standardize the instrument in a reflectance mode. Once standardized in reflectance, select “Opacity” to display in the Color Data View by going to Options/Read Method’.

A new window will open that allows you to choose Contrast Ratio Opacity as a read mode. Additional display options include the option to display:

  • Y Brightness value of the sample backed with the white backing which can be used to indicate the overall reflectance or luminous brightness as additional optical information.
  • Y Brightness value of the sample backed by black backing which is the second component of the Contrast Ratio Opacity calculation.

A typical display is just Opacity with some users selecting the Opacity, Yw combination.

Another option is the choice of an illuminant and observer for opacity reporting. Chose C/2 if you have no prior conditions. Once all of your selections are made click ‘OK’ to save and these metrics will be displayed in your Color Data View.

Put your mouse over the Color Data View/Right Click/Configure to select additional metrics such as CIE L*, a*, b* D65/10 color values as a complete quantifier of the color, or Yellowness Index E313 C/2 or D65/10 as a single quantifier for yellowness of white materials. Different metrics provide different optical information. Color values quantify the color of the sheet; contrast ratio opacity quantifies how opaque the sheet material is.
