The development trend of organic defoamers in the paper industry. The application research of active agents in the world is changing from a single multi-component type to a composite type. Countries around the world have allocated a large amount of human resource management and funds to the composite professional funds of organic defoamers. With investment and assets, many pioneering results have been achieved, and the comprehensive efficacy of organic defoamers has been significantly improved. The professionalism of organic preparation and its application shows a profound development trend. As an important part of the organic family, organic defoamers have the same development trend in the paper industry.

As we all know, in the high-efficiency paper industry represented by oleic acid amide, polyether, and organic materials, organic defoamers have completely replaced the traditional inefficient types of mineral oil, vegetable oil, alcohol, etc., and have made great contributions to the paper industry. Generally speaking, polyether silicone defoamers are converted from various starters. Silicone defoamers can be used as the basis for classifying polyether silicone defoamers. According to their differences, polyether silicone defoamers can be divided into polyol type and fatty acid ester type, that is, amine ether type. These types of defoamers have their own characteristics.

The analytical chemical structure is different from other organic defoamers. Non-specific groups are similar to non-optically active, and have no association with compounds containing water, hydrocarbon groups or optically active groups. Compared with other organic silicon defoamers, it can demulsify. Diligence, generally only need to add the molar mass of 1×10-6~75×10-6 managed by the system to obtain the expected effect of high-quality demulsification.

The physical properties are malleable to general compounds, and it is not easy to have exothermic reaction with foam compounds. Organic defoamers have good heat resistance and resistance to high and low temperature tests. The viscosity of methyl silicone oil gradually rises at about 200°C, and the silicon-oxygen bond does not dissolve. The methyl silicone oil has excellent flexibility and wettability. Therefore, the silicone defoamer is beneficial to improve the quality of coated paper.

Organic defoamers are safe, green manufacturing, and physiologically extended. This fashionable and intelligent manufacturing compound. Organic defoamers have anti-aging, process performance and anti-aging properties. They can be fully utilized under all geographical environmental standards. Organic defoamers have high The overall performance of quality, but the direct cost is higher. It can be applied to every production process in the paper industry, with high demulsification efficiency and sometimes unsatisfactory foam suppression effect.

Therefore, the organic defoamer can be compounded with other surfactants such as oleic acid amide and polyether with demulsification and foam suppression specificity to form a composite organic defoamer, which can not only improve the professional foam suppression ability of the organic defoamer, but also Reduce the direct cost of goods. With the professional development of surfactant compounding, organic defoamers have broad application market potential and huge market potential.
