Viscosity: The microscopic forces inside the liquid shape the macroscopic properties
Viscosity, for most people, may be a relatively unfamiliar word, but it plays a very important role in our daily lives. Viscosity is a key property of liquids, which describes how the interaction between molecules impedes the relative motion of the molecules under the action of external forces, thus affecting the flow properties of the liquid. The understanding and determination of this property is crucial for a wide range of fields, from chemicals to coating production. In this article,... 22Sep
Concept and determination method of non-volatile content
In the coatings industry, quality control is one of the key factors to ensure product performance and stability. One of the important quality parameters is the non-volatile content, which reflects the proportion of non-volatile components in the paint. In this paper, the concept of nonvolatile content, its determination method and its importance in coating production will be discussed in depth. The concept of non-volatile content Non-volatile refers to the material remaining after volatilization of the paint under specific test conditions. There... 22Sep
Reasons and countermeasures of paint film retraction
In the process of coating construction, paint film retraction is a common but troublesome problem. It will cause the coating to be uneven during the coating process, ultimately affecting the quality and appearance of the coating film. In this article, we will explore the causes of paint film retraction and how to effectively address this challenge. The flatness of coatings is usually affected by surface tension. Surface tension is a manifestation of the force exerted on the surface of the... 22Sep
Method for testing and sampling paint in its original state
introduction Coatings are chemical products that are widely used in a variety of applications, and their quality has a significant impact on the performance and appearance of the final product. In order to ensure the quality stability and consistency of coating products, it is necessary to carry out strict testing on its original state. In this article, we will explore the detection of paint in its original state and the importance of sampling methods to ensure that test samples are... 21Sep
The transparency of coatings and its detection method
introduction Transparency is a crucial property in paint production, reflecting the ability of a substance to penetrate light. Transparency not only directly affects the appearance and gloss of coating products, but also its performance and quality. In this paper, the importance of transparency in coating production and the detection method of transparency will be discussed in depth. The transparency of coatings and its detection method The importance of transparency Transparency has a profound impact on the quality and performance of coating products, and... 21Sep
Varnish color Determination of paint color
introduction In modern society, color is everywhere. It not only endows objects with beauty, but also conveys information and emotions. In the coating industry, color is one of the key characteristics of the product, which not only reflects the composition and purity of the coating, but also directly affects the film formation performance and use range of the product. This article will delve into the importance of color in the coating industry and the two commonly used color determination methods:... 21Sep
