Paper processing and papermaking
The papermaking and paper converting industry has always been an important manufacturing sector, and as requirements for environmental protection, performance and sustainability continue to increase, there is an increasing demand for new and innovative additives. VAE emulsion (ethylene-acetate copolymer emulsion) is widely used in the papermaking and paper converting industries due to its excellent adhesion properties, stability and environmental protection properties. This article will deeply explore the application advantages and specific application scenarios of VAE emulsion in the papermaking process, as well as its positive impact on paper properties.
Basic properties of VAE emulsion
VAE emulsion is a water-based emulsion composed of monomers such as ethylene and acetate. The following are the basic properties of VAE emulsions:
● Excellent adhesion properties: VAE emulsion can form strong bonds with cellulose and other pulp components during the papermaking process, improving the overall strength and durability of the paper.
● Water-based properties: As a water-based emulsion, VAE emulsion is compatible with water during paper preparation, helping to form a uniform coating and improving paper quality.
● Environmental protection: VAE emulsion does not contain organic solvents, has low volatile organic compound (VOC) emissions, meets environmental protection requirements, and helps create a greener papermaking process.
● Stability: VAE emulsion can maintain good stability during storage and use, and is easy to stir and mix, which is beneficial to the implementation of papermaking technology.
Application advantages of VAE emulsion in paper industry
● Improve paper strength: VAE emulsion, as an adhesive, can form a strong bond and improve the tensile strength, flexural strength and tear strength of paper.
● Improve the flatness of the paper surface: The addition of VAE emulsion helps to improve the flatness and smoothness of the paper surface, making the paper more beautiful.
● Improve the water resistance of paper: Due to the water resistance of VAE emulsion, its application in paper preparation can enhance the water resistance of paper and reduce the risk of moisture deformation.
● Reduce paper wrinkling and curling: The addition of VAE emulsion can improve the overall stability of paper and reduce wrinkling and curling in humid or high-temperature environments.
● Improve the wear resistance of paper: The film formed by VAE emulsion on the surface of paper can improve the wear resistance of paper and extend the service life of paper.
● Increase the flexibility of paper: VAE emulsion gives the paper a certain degree of flexibility, making it more elastic and slowing down paper breakage caused by external forces.
● Improve printing quality: The addition of VAE emulsion can improve the smoothness and printing performance of the paper surface, helping to improve printing quality.
Application scenarios of VAE emulsion in different paper types
● Cultural paper: In the preparation of cultural paper, the application of VAE emulsion can improve the flatness, strength and printing effect of the paper, and is suitable for books, magazines and other printed matter.
● Packaging paper: In the preparation of packaging paper, the addition of VAE emulsion can improve the wear resistance and water resistance of the paper, and increase the damage resistance and durability of the packaging paper.
● Coated paper: In the preparation of coated paper, the application of VAE emulsion can form a uniform coating and improve the surface quality and printing adaptability of the paper.
● Special paper: For some papers that require special properties, such as waterproof paper, oil-proof paper, etc., the addition of VAE emulsion can provide them with additional performance advantages.
● Toilet paper: In the preparation of toilet paper, the application of VAE emulsion helps to improve the softness, strength and water absorbency of the paper, and improves the user experience.
● Packaging box cardboard: In the preparation of packaging box cardboard, the addition of VAE emulsion can improve the strength and folding resistance of the cardboard and ensure the solidity of the packaging box.
As an innovative additive in the papermaking and paper processing industries, VAE emulsion provides a feasible way to improve the performance of paper through its excellent adhesion performance, stability and environmental protection characteristics. Its wide application in different types of paper makes the paper more water-resistant, wear-resistant, and fold-resistant while maintaining its traditional texture. In the future, with the continuous innovation of science and technology and the in-depth promotion of environmental protection concepts, the application prospects of VAE emulsion in the paper industry will be broader, providing more environmentally friendly and high-performance solutions for paper manufacturing.
