保定消光粉厂

日常生活中具有消光效果的物品随处可见：在家中，在上班的路上，或在夜幕下的餐馆里都可见其踪影。室内家具多采用了消光面，覆盖于餐馆外部的木质板材基本也消光外表。

Items with matting effect in everyday life can be seen everywhere: at home, on the way to work, or in restaurants at night. Most of the interior furniture uses matting surface, and the wooden board covering the outside of the restaurant basically also wears out the appearance.

当面临是选择亮光的还是消光的效果时，我们不仅仅局限于时尚和外观需求。实践证明，易清洁性，光亮效果及触摸感觉等方面的要求也影响着我们的选择。当我们 抵达办公室，不论是驾车，乘公共汽车还是坐火车，都会发现各类交通工具的内部装饰面基本是消光的。从实用和安全的方面考虑，学校的黑板都是采用消光表面避 免刺眼。轿车的内部也采用这类设计，一些经济实用的装置以及内部的装饰为了安全考虑均采用了不刺眼的消光漆。 

When facing the choice of light or extinction effect, we are not limited to fashion and appearance needs. Practice has proved that the requirements of cleanliness, brightness and touch feel also affect our choice. When we arrive at the office, whether we drive, take a bus or take a train, we will find that the interior decoration of all kinds of vehicles is basically dull. In terms of practicality and safety, blackboards are used to eliminate glare in school blackboards. This kind of design is also adopted inside the car. Some economical and practical devices and interior decoration are used for the safety consideration. It

       防反光是一项课题。摩天大楼表面一般不刷光亮的涂料，而是在钢或铝的基材上用预先涂漆的板材进行覆盖，且均使用用消光涂料，以避免产生危险的反光，刺激行人或汽车司机的眼睛。

Anti reflective is a subject. The surface of a skyscraper is usually painted without bright paint, but is covered with pre painted plates on the base of steel or aluminum, and using a light - extinction coating to avoid dangerous reflectors and to stimulate the eyes of pedestrians or drivers.

      此外，经济实用是选择涂料表面状态的另一个重要因素。比如，当某些基材被擦伤、有轻微凹坑以及弄脏时，采用消光涂料可以掩饰这些缺陷，而涂覆光亮漆却难以掩盖此类瑕疵。

Besides, economic and practical is another important factor to select the surface state of paint. For example, when some base materials are bruised, slight pits, and dirty, the use of extinction coatings can cover these defects, and the glossy paint is difficult to cover up such defects.

什么是消光效果？

What is the effect of extinction?

     什么是‘消光效果’？比如色彩，不论是消光还是光亮的外表，都是我们的感官所形成的一种主观印象。光线从一个平整的表面反射到我们的眼睛中，我们根据其光泽进行归类。(白色)

What is the effect of extinction? For example, color, whether it is light extinction or bright appearance, is a subjective impression formed by our senses. Light is reflected from a flat surface into our eyes. We classify it according to its luster. (white)

      精确地说，只有照射在表面的部分光线被直接反射回来，其余的进入漆膜，在内部散射开来，并被颜料和基材吸收。(黑色、黄色)

Only part of the light that is irradiated on the surface is reflected directly, and the rest enters the film and scatters inside it and is absorbed by the pigment and base material. (black, yellow)

      反射强度取决于表面的平整度。例如镜子，众所周知对光线反射率高，其表面十分光亮。相反地，微观粗糙的漆膜表面散射光线，只反射部分光线。在这个例子中，一个黄色的消光面出现了。

The intensity of reflection depends on the smoothness of the surface. A mirror, for example, is known for its high reflectivity and very bright surface. On the contrary, the surface of the microscopic rough film scatters light, reflecting only part of the light. In this case, a yellow extinction surface appears.

      获得一个完美的消光效果的条件是将所有的入射光散射开。这还意味者使照在基材上直射光线衍射开。否则，基材将会完全传送出光线，而形成光亮的外观。

The condition for obtaining a perfect extinction effect is to scatter all the incident light. It also means that the direct rays can be diffracted on the substrate. Otherwise, the substrate will completely transmit light and form a bright appearance.

获得消光漆面的基本要素

The basic elements of the extinction of the lacquer surface

      浮石粉在过去用于打磨干燥漆膜的外表面。通过加工获得细微擦痕，使漆膜具有精细的、高贵的消光外表。现在有更多的材料用于制造消光表面。尽管有些加工过程较 为复杂，但是却十分快捷。以硅石、石蜡、有机材料甚至填料为基础的添加剂，可以添加在涂料中，在干燥后能形成微观粗糙的漆膜表面。

The pumice powder used to polish the outer surface of the drying paint film. Fine scratches are obtained through processing, so that the paint film has a fine and noble finish. Now there are more materials for making matting surfaces. Although some machining processes are more complex, they are very fast. Additives based on silica, paraffin, organic materials and even fillers can be added to paint and form a rough surface on the surface after drying.

        溶剂型涂料施工后，溶剂立即开始挥发，伴随着粘度的增加，涂饰逐渐困难直至完全干燥，形成了坚硬又有弹性的漆膜。溶剂的挥发导致消光剂分布在整个漆膜表面，同时漆膜变薄。这种收缩是产生微观粗糙面的主要原因，或者换一种说法，即获得了一个消光的漆膜。 

After the construction of the solvent based coating, the solvent began to volatilize immediately. With the increase of viscosity, the coating was gradually difficult until it was completely dry, forming a hard and elastic lacquer film. The volatilization of solvent results in the distribution of matting agents on the surface of the entire film and the thinning of the film. This shrinkage is the main reason for producing microscopic rough surfaces, or in other words, a matting film is obtained. It

下图解释了为什么有机挥发物（VOC）含量高的比固含量高的涂料容易形成消光的效果。我们可以得出一个结论：树脂固含量越高，越难获得消光表面。UV或EBN系统几乎没有收缩，正是这些涂料如此难以获得消光效果的原因。

The following figure explains why the organic volatile matter (VOC) content is higher than that with high solid content, so that the extinction effect is easy to form. We can draw a conclusion that the higher the solid content of the resin is, the harder it is to get the extinction surface. UV or EBN systems have almost no shrinkage, which is why these paints are so difficult to obtain.

        也可以说，涂料漆膜越厚，越难获得消光表面。

It can also be said that the thicker the paint film is, the harder it is to get the matting surface.

二氧化硅的用途

The use of silica

       从硅石获得消光剂的方法很多，根据其制造工艺主要可以分为两类。一类是凝胶法，一类是沉淀法制造。经过处理后的两类产品均可制成标准的二氧化硅消光剂。处理过程是指使用有机(石蜡)或无机材料对二氧化硅表面进行一定程度的改性。处理过的二氧化硅拥有不同的粒径、粒径分布和孔隙体积。 

There are many ways to obtain matting agents from silica. According to their manufacturing technology, there are two main categories. One is the gel method, the other is the precipitation method. After treatment, the two kinds of products can be made into standard silica matting agent. The treatment process refers to a certain degree of modification of the surface of silica by using organic (Paraffin) or inorganic materials. The treated silica has different particle size, particle size distribution and pore volume. It

二氧化硅的消光效果相对较强，使用量大时可能导致粘度升高。储存过程中有沉淀的趋势，特别是未经处理的二氧化硅。

The extinction effect of silica is relatively strong, and the viscosity may be increased when the amount of silica is used. There is a tendency to precipitate during storage, especially untreated silica.

合成的硅酸铝能部分替代二氧化钛做为一种高质量增量剂使用，可应用于乳液底漆。该产物在干燥的乳液漆膜中能表现出均衡的消光效果。在长油醇酸树脂体系中可做为消光剂使用，但必须与颜料和填料一起进行分散。除了在粉末涂料系统中，二氧化硅消光剂可应用于所有的涂料。

The synthesized aluminum silicate can partially replace titanium dioxide as a high quality increment agent and can be applied to emulsion primers. The product can achieve a balanced extinction effect in the dry emulsion paint film. It can be used as a matting agent in long oil alkyd resin system, but it must be dispersed with pigment and filler. In addition to the powder coating system, silica matting agent can be applied to all coatings.

石蜡的用途

Use of paraffin

       现在，市场上有多种不同的石蜡制品。以聚乙烯、聚丙烯及巴西蜡等为基础的蜡制品在涂料和油墨中使用最为普遍。以聚四氟乙烯（PTFE）为基础的蜡制品也可做为消光剂使用

Now there are many different paraffin products on the market. Wax products based on polyethylene, polypropylene and Brazil wax are most commonly used in paints and inks. Wax products based on polytetrafluoroethylene (PTFE) can also be used as matting agents.

与二氧化硅相比，石蜡是通过浮在最外层表面对漆膜进

Compared with silica, paraffin wax is applied to the film by floating on the outermost surface.
