Papermaking, the process of converting waste paper into new paper, involves several key steps, such as pulp hydration, fiber separation, screening, and forming. It is critical to buffer these steps - that is, to use defoamers to effectively prevent bubble formation, thereby improving paper quality.   Common types of defoamers in papermaking The most commonly used defoamers in papermaking include silicone and polyether defoamers: 1. Silicone defoamers: These defoamers have excellent anti-foaming properties and high temperature resistance, which can minimize bubble formation to improve pulp fluidity. They are stable under various papermaking conditions and are a trusted tool for many. 2. Polyether defoamers: A non-ionic defoamer that is compatible with a variety of pH environments and chemicals, making it an indispensable player in papermaking, especially when used in combination with other additives.     Why use papermaking defoamers? The main function of defoamers is to reduce or eliminate bubbles in liquids. In the papermaking process, bubbles can lead to: 1. Reduced paper strength: Bubbles create weak points in the fiber structure of paper, reducing overall strength. This not only affects the utilization rate, but also increases the defect rate. 2. Poor uniformity: Bubbles disrupt pulp flow, resulting in inconsistent thickness and density, affecting product standards. 3. Reduced production efficiency: The presence of bubbles hinders pulp flow, which may cause equipment downtime and delays, increasing production time and costs.     Benefits of using defoamers In the papermaking process, defoamers bring many benefits: 1. Improve product quality: By effectively eliminating bubbles, improve the consistency and strength of paper, and ensure that the final product meets higher quality standards. 2. Improve production efficiency: Defoamers minimize bubble obstruction, ensure smoother pulp flow, increase overall production speed and shorten cycle time. 3. Reduce costs: By improving efficiency and product quality, defoamers help companies reduce raw material waste and thus reduce production costs. 4. Strong adaptability: Modern defoamers have excellent adaptability and can work effectively under different operating conditions (temperature and pH value), ensuring their effectiveness in different environments.   Papermaking defoamers play a vital role in the papermaking process. They can not only improve product quality, but also improve production efficiency, bringing significant economic benefits. With the advancement of technology, the types and properties of defoamers have continued to develop, expanding their applications in papermaking and other industrial fields.  

In industrial production, stirring is inevitable, and in water systems, foam will inevitably appear as long as stirring is done, and foam will cause many problems. Therefore, to eliminate harmful foam, we will use water-based defoamers.   From the literal meaning, it is not difficult to understand that defoamers are used to eliminate foam. Traditional defoamers use oil as a carrier, such as mineral oil, animal and vegetable oils, etc. However, with the increase in oil prices in the 1970s, the cost of oil-based defoamers also increased accordingly, so R&D personnel began to study more economical water-based defoamers, that is, using water instead of traditional oil-based carriers. It does not mean that the defoamer contains water, which means it is a water-based defoamer. The specific classification depends on the water content.     According to the water content of defoamers, they can be divided into the following types:   ① Oily: all oil is used as a carrier, that is, 100% oil content, no water;   ② Water containing: with water, the water content is less than 50%;   ③ Water-based: with water, the water content is greater than 50%;   ④ Water-based, oil-free: all water is used as a carrier, that is, 100% water content, no oil;     Although water was used instead of oil as a carrier in the early days, the effect was not stable, and the technology at that time was not developed enough. It was just diluting the traditional oily defoamer. It seemed that the cost was reduced, but the amount of addition used was greatly increased, so the overall cost did not decrease. However, with the advancement of technology, the performance of water-based defoamers is becoming more and more superior, and the scope of application is becoming wider and wider.

Pesticide defoamer is a chemical adjuvant that can inhibit the generation of foam during the spraying process of pesticides. Pesticides are prone to foaming when mixed with solvents such as water, which affects the spraying effect. Defoamers can reduce the surface tension of the liquid, quickly eliminate foam, and enable the pesticide to better cover the surface of crops and pests. Defoamers are often added to pesticide solutions to ensure effective spraying. Pesticide defoamer has two functions: 1. Defoaming: The surfactants contained in pesticides are prone to foaming, resulting in uneven spraying, weakened adhesion, and low droplet adhesion. Defoamers prevent the generation of foam by destroying the surface tension of the liquid, thereby improving the uniformity and effectiveness of pesticide spraying. 2. Synergism: Foam reduces the diameter of pesticide droplets and reduces the ability to adhere to the surface of plants, affecting the spraying effect. Defoamers can reduce the surface tension of liquids, prompt droplets to form larger and more uniform particles, and enhance the adhesion and absorption of pesticides on the surface of plants. Although defoamers play an important auxiliary role in pesticide spraying, they are not pesticides themselves and do not have the characteristics of directly killing insects or harming crops. Under normal use, defoamers are harmless to crops.   However, the correct method and dosage should be followed when using pesticides or pesticide adjuvants. Improper or excessive use may have a negative impact on crops and the environment. Therefore, the use of pesticides should follow the instructions and management regulations on the pesticide label and be used strictly in accordance with the correct method and requirements.  

In the vast field of modern industrial production, defoamers are the key to solving foam problems, and the defoamer manufacturers play a vital role.   Defoamer manufacturers are the source of technological innovation.
