The pulp and paper industry relies on a diverse range of chemical auxiliaries to ensure smooth operations and high-quality output. Among these, defoamers and antifoams are essential for managing the pervasive issue of foam generation. Foam can cause significant problems across multiple stages, from pulping to paper finishing. NINGBO INNO PHARMCHEM, a leading manufacturer and supplier of specialty chemicals in China, offers high-performance silicone defoamers that are vital for addressing these challenges. Understanding the specific applications where these defoamers excel is key for paper professionals.

In the initial pulping stages, such as brown stock washing and bleaching, the presence of lignin and other organic compounds creates substantial foaming. Uncontrolled foam here can hinder separation efficiency and impact chemical recovery processes. Our silicone antifoam defoamers are formulated to provide robust foam control in these aggressive, high-temperature, and high-alkali environments. They improve washing efficiency by ensuring better drainage, leading to cleaner pulp and reduced carryover to subsequent steps. This makes them an indispensable chemical auxiliary for pulp producers.

On the paper machine itself, foam can arise from various additives and aeration. This foam affects sheet formation, drainage, and overall paper quality. Silicone defoamers are crucial for maintaining the integrity of the paper web, preventing defects like pinholes and streaks, and ensuring efficient operation of the machine. Their ability to provide fast knockdown and persistent foam suppression makes them ideal for continuous processes.

Paper coating is another critical area where foam control is paramount. Foam in coating formulations can lead to uneven application, causing visual imperfections and affecting the paper's surface properties. Our silicone defoamers ensure a smooth, uniform coating layer, enhancing the final product's aesthetic and functional qualities. Furthermore, in wastewater treatment, managing foam in effluent systems is important for environmental compliance and operational safety. Our defoamers effectively control this foam, contributing to cleaner water discharge.
