Deciphering the application characteristics of fiber pulp defoamer

With the improvement of environmental protection awareness, pulp production has gradually shifted towards sustainable development. Many manufacturers have begun to adopt greener production methods, such as using recycled fibers, promoting renewable energy, improving wastewater treatment, etc., thereby reducing their impact on the environment. The generation of foam is a common problem, which will reduce production efficiency, affect paper quality, and pollute the environment. As a key auxiliary agent, fiber pulp defoaming agent has the ability to destroy and inhibit foam, providing a reliable solution for pulp manufacturing.
There are several reasons for adding defoaming agents during the pulp manufacturing process:

1. Control foam: During the pulp manufacturing process, a large amount of foam is easily generated due to factors such as mechanical stirring, gas release, and chemical reactions. The existence of foam will increase the operating pressure of the system, reduce production efficiency, and even cause equipment blockage or foam overflow. The addition of defoaming agents can destroy and inhibit the formation of foam, control the quantity and stability of foam, and thereby maintain the stability and continuity of the pulp manufacturing process.

2. High mechanical stirring effect: Mechanical stirring is often required during the pulp manufacturing process to achieve uniform dispersion and mixing of fibers. However, a large amount of air is introduced during the mixing process, resulting in a large amount of foam. If the foam is not controlled in a timely manner, it will lead to uneven mixing and affect the dispersion and mixing effect of the fibers. Adding defoaming agent can effectively reduce the generation of foam, improve the effect of mechanical stirring, and ensure the dispersion and uniformity of fibers.

Fiber pulp defoaming agent has the following characteristics:

1. Low dose and high efficiency: The amount of defoaming agent used in paper pulp is very small, but it can produce significant foam control effect. This means that the addition of defoamers does not cause additional chemical components to the pulp preparation process, thereby complying with process requirements.

2. Does not affect paper quality: It will not have a negative impact on the quality of the paper, and will not change the physical properties and surface smoothness of the paper. This is critical to the final quality of the paper.
