    Application of Defoamer in Electroplating
    Electroplating is the process of coating a thin layer of other metals or alloys on certain metal surfaces. When it comes to electroplating, it is naturally associated with electroplating solution. It refers to a liquid that can expand the cathode current density range of metals, improve the appearance of coatings, and increase the stability of solution oxidation resistance. Through the electroplating process, products with different metal glosses can be obtained, which are more popular in the market. Therefore, the electroplating process is very important. However, in the actual process application, the electroplating process will also produce foam, which requires the use of electroplating defoamer. In production and application of electroplating, due to the excessive organic substances in the bath, too high concentration of pickling solution, too much impurities. And there is still an oxide film on the surface before entering the plating bath, the electroplating solution will produce a large number of foam. Bad consequences of too much foam: 1. It will lead to increased costs. 2. Cleaning agent has Excessive loss. 3. It will affect the quality of electroplating. 4. It will affect the normal operation of the machine. After systematic research and on-site testing, defoamer used in the electroplating solution is refined from a specially modified organic polymer, belonging to high stability products with excellent defoaming function, will not cause emulsion breaking, oil floating, oil bleaching, precipitation and other phenomena, and has no obvious impact on the production of subsequent processing.

  • The World's Largest Pulp Producer: Considering Exporting Products to China in RMB
    The World's Largest Pulp Producer: Considering Exporting Products to China in RMB
    Suzano SA, the world's largest producer of hardwood pulp, is considering selling its products to China in RMB, further indicating that the US dollar is gradually losing its dominant position in the commodity market. Walter Schalka, chief executive of Suzano SA, said in a previous interview that RMB was becoming increasingly important and some customers in China were also willing to trade in RMB. Currently, the US dollar still dominates global trade settlement, the speed of switching to RMB in various commodity contracts from oil to nickel is accelerating. Schalka said he believes that the US dollar will become less important in the future, but he also pointed out that the renminbi still needs further transformation. He believes that the tense geopolitical relationship between China and the United States is the main concern of the company, as it may suppress demand and prices of pulp for a long time. According to public information, Suzano SA is the world's largest producer of hardwood pulp, headquartered in Brazil, with a share of approximately 15% in the global hardwood pulp market in 2020. China is the largest commodity buyer and also accounts for 43% of Suzano's pulp sales.

  • Lightest Paint Inspired By Butterfly Wings
    Lightest Paint Inspired By Butterfly Wings
    Plasma coating was applied to the wings of metal butterflies, and it was this insect that sparked the research. Researchers at the University of Florida in the United States drew inspiration from butterfly wings to develop a new energy-saving paint that is natural and environmentally friendly.This coating is not made of pigments, but uses the nanoscale structure of colorless materials such as aluminum and aluminum oxide to produce color, making it very environmentally friendly. This alternative to pigment colorants can help save energy and slow down global warming. By arranging them at the top of the oxide coated aluminum mirror in different ways, the scattering, reflection, or absorption of light can be controlled. The rich colors of butterfly wings follow a similar principle. Debashim Chanda, University of Central Florida Nanoscience and Technology Center professor said, because the pigment gradually loses its ability to absorb photons,the normal color fades.But structural paint is not limited by this phenomenon, and once applied, it should remain for centuries. According to the scientists' calculations, it takes only 1.4 kilograms of plasma paint to cover the surface of a Boeing 747. Conventional commercial paint requires at least 454 kilograms to get the same effect.This means that it can significantly reduce the greenhouse gas emissions generated by aviation coatings. In addition, plasma coating absorbs less heat, its undersurfaces are cooler than those covered by commercial coating.     Plasma paint is light.This is due to the large area-to-thickness ratio of this coating, which achieves full coloration at a coating thickness of only 150 nanometers, making it the lightest coating in the world. The paint is still a long way from mass production.

  • Defoamers for Industrial Water Treatment
    Defoamers for Industrial Water Treatment
    Defoamer for industrial water treatment is a widely used chemical. Its main function is to remove foam during water treatment. Defoamer can quickly break bubbles in water and prevent bubbles from forming again. Its principle is to destroy the surface tension in water through the action of surfactants, causing bubbles in the water to burst. Surfactants can be classified into various types, including anionic surfactants, cationic surfactants, and non-ionic surfactants. In water treatment, non-ionic surfactants are generally used as the main defoamer. Defoamers for industrial water treatment can not only remove foam, but also improve the water treatment effect. In addition, defoamers can reduce energy consumption and production costs, and improve the economic benefits of industrial production. According to its different properties and uses, it can be classified into different categories. According to their different chemical composition,it can be divided into organic antifoam agent and inorganic antifoam agent. Organic antifoam agent has good foam inhibition effect and is suitable for most water treatment processes. Inorganic antifoam agent has a weak inhibition effect on foam in water, but has a good removal effect on colloidal and floating matter in water. Regarding its application and effect, it can be divided into surfactant antifoam agent and inert-gas antifoam agent. Surfactant antifoam agent has good antifoaming effect, but they may cause pollution to water bodies during use. The inert-gas antifoam agent can effectively eliminate the foam in water, and will not cause pollution, but its price is relatively high. For sewage treatment in different industries, different components of defoamers can be selected for defoaming and foam suppression.

  • Non-wood fiber materials at the forefront of innovation in the European paper industry
    Non-wood fiber materials at the forefront of innovation in the European paper industry
    Recently, the European Paper Industry Confederation (Cepi) commissioned the nova-Institute, a private research institute in Germany, to conduct a survey on 33 non-wood pulp producers in Europe. The report shows that non-wood fiber still has great potential in promoting the sustainable development of the pulp and paper industry. This study investigated almost all types of non wood fiber materials used by European non-wood pulp producers, from agricultural residues, by-products and specialized non-wood fibers to materials such as straw, flax and hemp, as well as the textile industry of waste. It is found that these non-wood fibers can help the pulp&paper industry to achieve the diversification of fiber raw materials and improve the availability of fiber. In addition, non-wood fibers are likely to be an important driving force for process and product innovation in the paper industry in the future, for example, some specific properties of crop and agricultural residue fibers can be used to develop new biological materials. At present, non-wood fibers are widely used in Europe. It can already be used to produce tissues, toilet paper, printing paper, cigarette paper, anti-counterfeiting paper, and other special paper and cardboard, as well as the recently popular food packaging cardboard. This not only compensates for the shortage of raw materials in the paper industry, but also improves the circularity of agricultural and textile sectors. In the future, European manufacturers will continue to cooperate in the research and development of other uses of non-wood fiber materials. In this regard, Cepi said: "Sustainable management of raw material procurement and a high degree of circularity remain the defining characteristics of the European paper industry. In the future, non-wood fibers will continue to play a role and become an important raw material for paper mills and recycling plants. Paper Industry will effectively utilize non-wood fiber resources and achieve higher added value." During the pulp and paper process, the antifoam is the basic for solving excessive foam problem!

  • How to choose defoaming agent?
    How to choose defoaming agent?
    The selection of defoamer should comply with the following points: 1. Insoluble or difficult to dissolve in foaming fluid To break the foam, the defoamer should be concentrated on the foam film. When it breaks the foam, it should be concentrated instantly, and it should also be kept in this state when suppressing the foam. Therefore the defoamer should be supersaturated in the foaming solution, and only insoluble can it easily reach a supersaturated state. Only when it is insoluble or difficult to dissolve, it is easy to aggregate at the gas-liquid interface, easy to concentrate on the bubble film, and play a role at lower concentrations. For defoamer used in water systems, the molecules of the active ingredients must be strongly hydrophobic and weakly hydrophilic, with an HLB value in the range of 1.5-3 for the best effect. 2. The surface tension is lower than that of the foaming liquid Only when the intermolecular force of the defoamer is small and the surface tension is lower than that of the foaming solution, can the defoamer particles immerse and expand on the foam film. It is worth noting that the surface tension of the foaming solution is not the surface tension of the solution, but the surface tension of the auxiliary foaming solution. 3. Has affinity with the foaming fluid  To make the defoamer diffuse faster, the active ingredient of the defoamer must have affinity with the foaming fluid.If the active ingredient of the defoamer is too close to the foaming liquid, it will dissolve; if it is too sparse, it will be difficult to disperse. Only when the closeness is appropriate can the effect be good. 4. No chemical reaction with foaming fluid Defoamer reacts with foaming fluid. On one hand,the defoamer will lose its effect, on the other hand, it may produce harmful substances to affect the growth of microorganisms. 5. Small volatility, long action time The first step is to determine the system in which the defoamer needs to be used,a water-based system or an oily system. As the fermentation industry,it is necessary to use oily defoamers, such as polyether modified silicon or polyether.Water - based paint industry will use water - based defoamers, such as silicone defoamers.Selecting defoamers, comparing the amount added,the reference price, will can obtain the most suitable and economical defoamer products.
