Interview "Pigments could act as sustainable power sources"
“颜料可用作可持续能源”
We have talked to Özlem Ünlü Isık, R&D Lab Manager – Automotive Coatings at Kansai Altan, about current trends of the pigment market and the functionalities of pigments regarding automotive coatings.
我们采访了关西阿勒坦Kansai Altan汽车涂料研发实验室经理Özlem Ünlü isikk,讨论了当前颜料市场的趋势以及颜料在汽车涂料中的功能.
Özlem Ünlü Isık: "For low VOC and high solid paints, particle size, morphology and surface treatment of organic pigments should be improved."
Özlem Ünlü iszakk:“对于低VOC和高固含的涂料来说,有机颜料的粒度,形貌和表面处理都应该改进.”
What trends will influence the pigment market regarding automotive coatings?
哪些趋势将影响汽车涂料颜料市场?
Özlem Ünlü Isık: Global trends such as saving resources, digitalization, electric vehicles, climate change and even pandemic situation influence the pigment market and colour trends in a certain direction.
Özlem Ünlü iszakk:节约资源、数字化、电动汽车、气候变化甚至疫情大流行等全球趋势都在一定方向上影响着颜料市场和色彩趋势.
Products offered by the automotive industry often have - somewhat - similar designs. Surveys show that one of the primary criteria for consumers is individuality. Considering the recent developments in technology and the speed in change of colour trends, it would not be surprising in the future to instantly change the colour of pigments on a vehicle just by pressing a button and choosing any colour from a wide range of spectrum.
汽车行业能提供的产品通常设计非常接近.
但调查显示,消费者的一个主要选车标准是个性.考虑到最近技术的发展和颜色变化趋势的速度,将来,只需按下一个按钮,从广泛的光谱中选择任何一种颜色,就可以立即改变车辆上颜料的颜色,将来这样的发展并不是十分稀奇.
As colour and appearance are fundamental elements of the perceived quality; unique colour design is crucial to serve individuality. Style departments, pigment and paint producers are cooperating continuously to find the optimum eye-catching colours resulting in high consumer demand.
由于颜色和外观是感知质量的基本要素;独特的色彩设计是服务个性的关键.时尚部门,颜料和涂料生产商不断合作,以找到最佳的醒目颜色,从而满足消费者的高需求.
Effect pigments are among the primary components for individuality and differentiated appearance. Automotive industry benefits from the superior properties of effect pigments which offer vivid chromaticity by expansion of colour and appearance space such as coloured metallic, high sparkle effect and high interference pigments.
Brightness, good hiding power have gained significant importance for effect pigments. One of the main challenges of chromatic expectation in individuality is hiding power, whereas the mechanical performance is optimised via pigmentation level and film thickness. Higher pigmentation levels may often lead to mechanical and cohesive failures. Therefore, stronger hiding power at lower pigmentation and lower film thicknesses would lead to less paint and energy consumption.
效果颜料是个性和差异化外观的主要组成之一.
汽车工业受益于效果颜料的优越性能,如有色金属颜料,高闪耀效果和高干涉颜料等,通过扩大颜色和外观空间提供生动的色彩.
亮度,良好的遮盖力对效果颜料具有重要意义.
个性色度期望的主要挑战之一是遮盖力,而这一能力的实现,靠的是通过色素水平和薄膜厚度来优化的机械性能.较高的色素沉着水平往往会导致机械性能损耗和内聚失效.因此,以较低的色素沉着和较低的成膜厚度来实现的较强的遮盖力,就能减少涂料和能源消耗.
On the other hand, lean and compact designs, urban mobility and car sharing influence the colour trends towards a more conventional neutral direction and natural palette.
另一方面,精简紧凑的设计、城市流动性和汽车共享影响了色彩趋势,使其朝着更传统的中性方向和自然色调发展.
Autonomous driving with the expected outcomes of flexibility, safer travel, driving comfort and efficiency have inevitable impacts on the pigment technology to be chosen in the long run. Self-driven cars communicate with their environment through RADAR-LiDAR systems. Therefore, pigment selection can influence signal transmission from vehicles and signal reflection from objects in the surroundings.
对自动驾驶的灵活性,出行安全,驾驶舒适性和效率的预期需求,长远来看,对颜料技术产生了不可避免的影响.
自动驾驶类汽车是通过雷达-激光雷达系统与周围环境进行通信的.因此,色素的选择可以影响车辆信号的传输和周围物体信号的反射.
For low VOC and high solid paints, particle size, morphology and surface treatment of organic pigments should be improved. Crystal and molecular design of organic pigments should be well studied. Universal easy dispersible high-performance pigments will be highly appreciated by paint producers. Grinding pigments will be simplified if such kind of pigments are marketed.
对于低VOC、高固含涂料,有机颜料的粒度、形貌和表面处理是应当改进的部分.有机颜料的晶体和分子设计有待进一步研究.通用易分散的高性能颜料将受到涂料生产商的高度重视.如果这类颜料上市,研磨颜料将会简化.
Do you expect a demand for new functionalities of pigments?
你认为对颜料的新功能有需求吗?
Özlem Ünlü Isık: There is an increase in demand for pigments with functional benefits. Energy harvesting from any coated surface offers alternative energy supply. Pigments could act as sustainable power sources. Pigment particles to be excited by solar radiation may be used in conductive resins to produce electricity.
Özlem Ünlü iszakk:对功能性颜料的需求有所增加.从任何涂层表面收集能量提供替代能源供应.颜料可以作为可持续能源.被太阳辐射激发的颜料颗粒可用于导电树脂中以产生电力.
Paint formulations benefit from the barrier effects of pigments for various insulation purposes. Minimum IR absorbing cool colours are preferred for decreasing the impacts of heat-island and saving energy. Moreover, better UV resistant pigments that will protect the polymer from degradation are needed for longer term protection of exterior surfaces.
涂料配方受益于各种绝缘目的的颜料的屏障作用.为了减少热岛的影响和节约能源,人们往往青睐拥有最小IR折射吸收率的冷色系.此外,为了长期保护外表面,还需要更好的抗紫外线颜料来保护聚合物不被降解.
It is expected that the increasing demand in car sharing will necessitate a superior chemical resistance for interior coatings. Surface treated effect pigments will serve to increase the expected chemical resistance.
预计汽车共享需求的不断增长将使内饰涂料具有优异的耐化学性成为必要.表面处理的效果颜料将有助于增加预期的耐化学性.
