In the papermaking industry, silicone oil emulsion is gradually becoming an important additive to enhance paper performance.
Hydroxyl silicone oil emulsion is a commonly used type, which can be applied to the surface treatment of paper. On the one hand, it can endow paper with good water resistance. When the paper comes into contact with moisture, it is not easy to penetrate and deform, which greatly improves its performance in humid environments. It is very suitable for the production of packaging paper, waterproof paper and other products. Tests show that after being treated with hydroxyl silicone oil emulsion, the tensile strength of packaging paper decreases by 40% less than that of untreated paper when placed in an environment with 80% humidity for 24 hours.
On the other hand, silicone oil emulsion can improve the softness and smoothness of paper. This makes the text and patterns clearer and more beautiful when writing and printing on paper, playing a key role in the production of cultural paper and high-grade packaging paper. Relevant data show that the coefficient of variation of ink absorbency of cultural paper after treatment has decreased by 30%, and the printing effect has been significantly improved.
In addition, when amino silicone oil emulsion is applied to the paper coating, it can also improve the smoothness of the paper surface and printing adaptability. After penetrating into the fiber, it can enhance the wet strength and flexibility of the paper, which is beneficial to the long-term preservation of documents. With its diverse properties, silicone oil emulsion has brought new development opportunities to the papermaking industry and helped to continuously upgrade the quality of paper.
