消光粉和消光剂都能起到使目标材料消除光泽的作用，但一个“粉”一个“剂”，它们有着哪些区别？
The extinction powder and the extinction agent can all play a role in eliminating the gloss of the target material, but what are the differences between a "powder" and a "agent"?
消光粉是一种易分散的化学粉末，是涂料助剂的一种。常见的消光粉包括白炭黑、滑石粉。消光粉具有“直接涂抹”的特点，使用方法简单。原材料也易于得到。
The extinction powder is a kind of easily dispersed chemical powder, and is one of the additives of the coating. The common extinction powder includes white carbon black and talcum powder. The extinction powder has the characteristics of "direct smear", and the use method is simple. The raw material is also easy to get.
消光剂则是带有环氧基的消光树脂材料。也属于涂料助剂的一种。常见的消光剂包括纯聚酯消光树脂、纯聚酯消光剂、有机消光剂、白炭黑消光剂。消光剂通过其极细微的悬浮物分散于涂料之中，涂料成膜后这些悬浮物会分散于涂膜表面，增加了涂膜粗糙度而起到降低涂膜反光度的作用。消光剂的主要品种包括金属皂、蜡、硅藻土、合成二氧化硅等。
The extinction agent is an epoxide - based light - extinction resin. It is also a kind of coating additives. The common extinction agents include pure polyester extinction resin, pure polyester extinction agent, organic light elimination agent, and white carbon black light elimination agent. Matting agent is dispersed in the coating through its very fine suspension. After coating, the suspended solids will disperse on the surface of the coating, which will increase the roughness of the coating and reduce the reflection of the coating. The main varieties of the extinction agent include metal soap, wax, diatomite, synthetic silica and so on.
消光粉的消光机理是：通过添加有消光作用的填料，如滑石粉、超细二氧化硅等填料使涂膜光泽度降低；通过添加热塑性树脂如醋酸纤维素、聚丙烯树脂等使涂膜光泽度下降；
The extinction mechanism of extinction powder is: by adding filler with light extinction effect, such as talcum powder and ultrafine silica filler, the gloss of film is reduced; the gloss of film is decreased by adding thermoplastic resin, such as cellulose acetate and polypropylene resin.
消光剂的消光机理则是：通过消光剂粒子广泛分散于涂膜表面，当紫外光线照射在涂膜粗糙表面时，将形成光线散射，粗糙度越大，光线越散射，从而实现哑光或不反光的消光效果。
Extinction mechanism matting agent is: through delustrant widely dispersed in the particle film surface, when ultraviolet light irradiation in the film will form a rough surface, light scattering, surface roughness increases, the light is scattered, so as to realize the matte or non reflective extinction effect.
消光粉中的金属皂其实是人们较常用到的一种消光剂。金属皂与涂料成分不相容，而能以细小的颗粒悬浮于涂料中，成膜后发布在涂膜表面，这里可以看出，效果粉与消光剂在一定程度上是概念重合的，它们的基本消光原理和基本功效是一样的。比如硅藻土、高岭土、白炭黑等都是专门用于涂料消光的功能性消光粉，它们使用原理都是会在涂膜表面悬浮，留下粗糙的凹凸表面以形成散射光线。这些因素也是消光剂的基本因素。
The metal soap in the extinction powder is actually a kind of extinction agent commonly used by people. Metal soap and coating composition is not compatible, and with tiny particles suspended in paint, after the film released on the film surface, it can be seen that the powder and the extinction effect agent to a certain extent is the concept of coincidence, basic principle and basic functions of their extinction is the same. For example, diatomite, kaolin and silica are all functional matting powders specially used for coating extinction. Their principles of use are suspended on the surface of the coating, leaving rough rough surfaces to form scattered light. These factors are also the basic factors of the extinction agent.
