Analysis of the core advantages of papermaking defoamers

In the process of paper production, foam has always been a key factor affecting product quality and production efficiency. As an efficient functional additive, papermaking defoamers provide solutions for modern paper industry from multiple dimensions such as efficiency, quality, and environmental protection. It can quickly eliminate and restrain foam.

A large amount of foam will lead to the decline of pulp fluidity, increase the energy consumption of pumping and mixing, and even cause equipment idling. Defoamers can quickly destroy the stability of foam and reduce the air content in the slurry, thus optimizing the fluid performance, reducing energy consumption by 10% -20%, significantly improving the speed of the production line and reducing energy consumption.

In addition, a large number of foam residues will form pinholes, holes or color spots on the paper surface, affecting the uniformity and strength of the finished product. High efficiency defoamer ensures the uniform distribution of fiber, improves the smoothness, tensile strength and printability of paper, improves the quality of paper, and expands the consumption market of paper by precisely controlling the generation of foam.

Modern defoamers (such as organosilicon and polyether) use environmentally friendly formulas, do not contain heavy metals or harmful solvents, and comply with international environmental standards. Its low addition amount (0.01% -0.1%) can be effective, reducing the burden of wastewater treatment, promoting green production, and having strong environmental compatibility. Whether it is acidic or alkaline pulping, high-temperature bleaching, or high-speed paper machine environment, the defoamer can maintain stability. Adapt to complex process conditions and meet diverse production needs.

Although the unit price of defoamer is high, it can reduce the downtime, raw material waste and defective product rate caused by foam. According to statistics, the reasonable use of defoamers can reduce comprehensive production costs by 5% -15%, and the return on investment is significant.
