Surface sizing of paper is a key processing method that improves its optical properties, physical properties, and printability by applying compound to the surface of paper. This article will delve into several important factors that affect the impact of surface sizing technology on paper.
Improvement of water resistance
Surface sizing technology has a significant effect on the water resistance of paper. In printed and packaging paper, surface sizing can form a protective film that effectively prevents moisture from penetrating. This protective film not only reduces the moisture absorption on the surface of the paper, but also improves the wet strength and moisture resistance of the paper, making it stable in wet environments.
Optimization of ink absorption and printability
In the printing industry, the sizing treatment of the paper surface can adjust its absorption characteristics of the ink, thereby affecting the quality and stability of the printing effect. By controlling the type and concentration of the sizing agent, the paper surface can be formed with better ink absorption properties suitable for different types of inks. Especially for the application of high-gloss inks, surface sizing can effectively reduce the amount of ink absorption on the surface of the paper and ensure the clarity and color saturation of the printed matter.
Improved rubbing and abrasion resistance
The erasability of a paper refers to whether the surface of the paper can be restored to its original clear state after the blot is erased. Surface sizing technology significantly improves the rubbing properties of the paper by increasing the smoothness and friction resistance of the paper surface. This is especially important for writing paper and applications that require frequent scribble erasure, ensuring the visual and quality stability of the print over time.
Enhancement of strength and stability
Surface sizing can not only improve the surface strength of the paper, but also enhance the overall mechanical properties of the paper. By increasing the bond strength of the fibers on the surface of the paper, surface sizing effectively improves the bursting, bending and tensile strength of the paper. This makes the paper not easy to produce problems such as fluffing and paper drop in the process of high-speed printing and complex processing, and ensures the stability and efficiency of the printing process.
As an important means of paper processing, surface sizing technology not only performs well in improving the optical properties and physical properties of paper, but also has a significant role in promoting the printability, durability and environmental performance of paper. With the increasing demand for high-quality, multi-functional paper, the application prospect of surface sizing technology will be broader.
