With the continuous development of science and technology and the continuous expansion of global industries, defoaming agents are gradually emerging as chemicals widely used in many industries. The function of defoaming agents is to inhibit the formation and stability of foam in liquids, thereby improving production efficiency and quality. This article will explore the wide range of applications of defoamers in different industries and the positive impact they have on these industries.   1. Food and Beverage Industry The food and beverage industry is one of the main application areas for defoaming agents. During food processing, many foods and beverages generate foam, which can harm the production process and product quality. The introduction of defoaming agents can effectively reduce the generation of foam, improve production efficiency, and ensure product quality and consistency. For example, they are widely used in beer production to control the foam produced during fermentation and ensure the quality of beer.     2. Pharmaceutical industry The pharmaceutical industry is another area where defoaming agents are widely used. In pharmaceutical production, the mixing and stirring process of drugs may produce large amounts of foam, which may interfere with the drug production process and reduce the purity of the drug. The application of defoaming agents in the pharmaceutical process helps maintain the stability of the production process, ensure the quality of the drug, and reduce foam interference during the production process.   3. Chemical Industry In chemical production, defoaming agents are widely used in various processes, especially in reactors. Chemical reactions are often accompanied by the release of gas, which results in foaming. The addition of a defoaming agent can effectively reduce the generation of foam, improve the efficiency of the reactor, and reduce instability factors caused by foam, thereby improving the quality of the product.   4. Papermaking and Textile Industry In the paper and textile industries, foam generation is often a problem during the production process. In the papermaking process, air bubbles in the pulp can cause paper quality to deteriorate, while in the textile industry, foam can interfere with dyeing and coating processes. Applying defoaming agents helps solve these problems and improves the quality of paper and textiles.     5. Oil and natural gas industry During oil and gas extraction, the release of gas from liquids is often accompanied by the generation of foam. This can lead to fluid flow instability and reduce mining efficiency. The introduction of defoaming agents can effectively reduce the generation of foam, improve the efficiency of oil and natural gas production, and reduce the waste of energy resources.   6. Environmental protection and water treatment In the fields of environmental protection and water treatment, the application of defoaming agents is also in...

Self-levelling mortar has been increasingly recognised as a floor levelling material. Self-levelling mortar is mainly made of adhesive, sand, filler, superplasticiser, retarder, coagulant promoter, defoamer and other more than 10 kinds of materials pre-mixed by the factory, which has good stability. Self-levelling mortar has high requirements for flow, apparent state, shrinkage and strength, which requires us to select all raw materials used for self-levelling mortar to meet the performance requirements of the material. Defoamers have different chemical structures and properties, different foam systems, different foam suppression, foam breaking stability, foam breaking rate, etc.. Defoamer used in the mortar, at the same time to be chemically inert, as far as possible, does not affect the other properties of the mortar. Defoamer on the flow of self-levelling mortar effect After adding defoamer in cement-based self-levelling mortar system, it can make self-levelling mortar flow degree increase, change the apparent state of the mortar after hardening, increase the wet density of the mortar, so as to make the self-levelling mortar hardened compressive and flexural strength level increase. Adding defoamer helps flow, but there are differences in the suitability of different types of defoamer and the whole mortar system, and there are also differences in the effect of flow. The effect of defoamer on the wet density of self-levelling mortar The addition of defoamer on the self-levelling mortar wet density growth is very fast. However, different types of defoamer on self-levelling mortar wet density changes slightly different, so different types of defoamer applied to the same self-levelling mortar system defoaming ability there are differences. Appropriate prolongation of the resting time, self-levelling mortar wet density will increase slightly, so self-levelling mortar mixing, can be appropriately prolonged after the resting time, in order to enhance the anti-foaming ability of self-levelling mortar. The effect of defoamer on the apparent state of self-levelling mortar Add defoamer self-levelling mortar after hardening the apparent state is changed. After mixing the self-levelling mortar, the appropriate prolongation of the wet mortar standing time can improve the defoaming ability of the self-levelling mortar, so that the apparent state of the hardened self-levelling mortar has been further changed, so that the surface of the mortar is free of small pinholes, and has a better homogeneity. Influence of defoamer on the strength of self-levelling mortar The compressive and flexural strength of self-levelling mortar increases with the addition of defoamer. The flexural strength of self-levelling mortar is increased from F4 strength grade to F6 strength grade or above, and the compressive strength is increased from less than C16 strength grade to C20 strength grade or above. However, there are differences in the effects of different types of defoamers on...

In recent years, with the rapid growth of the national economy and the continuous improvement of people's living standards, the production and sales of paints in China have been growing at a faster rate. However, compared with developed countries, the consumption structure of paint products in China is not very reasonable. Highly polluting paint products still occupy a large market share, which brings more serious harm to the environment and the health of construction workers. With the enhancement of people's awareness of environmental protection and the increasing improvement of environmental protection regulations, countries around the world are encouraging and promoting the use of green, energy-saving, and material-saving new paint products. Among them, water-based coatings are beneficial to the rational use of resources, prevent environmental pollution, protect human health, and do not contain or contain less VOC (volatile organic compounds) and harmful air pollutants (HAP). This has become a hot spot for research and development, promotion, and application of highlights and growth points. Compared with other low-pollution coatings, water-based coatings have become the preferred varieties because of their achievable technical ways, wide application, safety, and relatively simple construction. It is more concerning to the majority of coating scientists and coating users. In recent years, it has been developed to a certain extent in China and has received unprecedented attention. However, the share of water-based coatings in the industrial coating field is still small. Therefore, improving the proportion of water-based industrial coatings, reducing pollution in the environment, and reducing the health hazards of construction personnel have become common issues facing the coating industry in China.   Classifications of water-based coatings Distinguished by dispersion form, water-based coatings include water-soluble coatings, water-dilutable coatings, and water-dispersible coatings (latex coatings). Their dispersion mechanisms are different, and the performance of the products also has a big difference. However, regardless of the type, they all use water as a solvent or dispersion medium. According to the distinction between film-forming substances, water-based coatings can be divided into water-based acrylic coatings, water-based polyurethane coatings, water-based epoxy coatings, and so on. In recent years, the film-forming substances of water-based coating products have had a tendency to develop in the direction of mixed modification. Characteristics of water-based coatings The most important feature of water-based coatings is to use water instead of organic solvents as solvents or dispersion medium, which saves a lot of organic materials (petroleum) resources and greatly reduces pollution of the atmosphere and the fire hazard during the construction process by volatilizing organic solvents in the coatings. In addition, with water-bas...

The continuous development of science and technology has led to the birth of reverse osmosis membrane separation technology. It is different from the natural separation and purification methods of the past. While this technology can provide business owners with the benefits of accelerated project schedules, it also comes with the difficulty of eliminating bubbles. It is common for a large amount of foam to appear during the reverse osmosis water treatment process. This is mainly caused by the various surfactants contained in the wastewater, which will continue to generate foam in the water source. After all, water itself is a fluid medium, and these foams have limited self-purification capabilities and must be effectively removed with the help of reverse osmosis water treatment defoamer. Reverse osmosis water treatment defoaming agent is a non-silicon product prepared from polyether esterification products through a special process. It is a highly efficient defoaming agent specially developed for various biological water treatment systems.   Reasons for foaming during reverse osmosis water treatment: 1. The aeration volume is too large, the air-water volume ratio is unreasonable, and the oxygen is supersaturated, resulting in foam formation. 2. During the operation stage of sewage treatment, a large number of filamentous bacteria and actinomycetes continue to grow in the water body, which can easily form a large amount of foam. 3. Excessive air supply or oxygen during biological water treatment will produce a large amount of foam, which will affect the water treatment process or overflow conditions and adversely affect activated sludge and bacteria. 4. The sewage contains too many surfactants and other additives. Advantages of reverse osmosis water treatment defoamer: 1. It has no side effects on various fungi in general water species and will not damage the film layer. It is an environmentally friendly defoaming agent. 2. It has good dispersibility in water, is fully compatible with liquid products, and will not break emulsions and floating oil layers. 3. It has strong defoaming and anti-foaming ability, low dosage, and does not affect the basic performance of the foam system. 4. It has good heat resistance, chemical stability, non-corrosiveness, non-toxicity, no adverse side effects, no combustion, and no risk of explosion. 5. The dosage is small, the cost is low, and it has a wide range of applications.

Whether in the chemical, construction, textile, or food industries, foam may cause problems in the process and even cause production line shutdowns. Therefore, defoaming agents, as a tool to solve foam problems, are not only of great significance to industrial production, but also play a positive role in improving production efficiency and quality.    Alcohol defoamer manufacturers realize that to solve the foam problem, the power of   one manufacturer alone is far from enough. Therefore, they actively seek professional   partners to jointly develop innovative solutions. These partners come from various   fields, including scientific research institutions, university laboratories, engineering   technology companies, etc. Through cooperation, alcohol defoamer manufacturers can obtain more resources and expertise and apply them to product development and production.   During the cooperation, alcohol defoaming agent manufacturers and partners carried out extensive technical exchanges and cooperative research. They jointly overcome the foam problem through the construction of cooperative laboratories and the sharing of equipment. Through communication and research, they continuously improve the performance and quality of their products and develop more efficient alcohol defoaming agents, providing better solutions for industrial production.   In addition, alcohol defoaming agent manufacturers also work closely with their partners to jointly develop the market. They understand market development trends and potential needs through market research and customer demand analysis, and formulate product  positioning and marketing strategies based on actual conditions.

Part One: the standard of selecting a good powder type defoamer   Step 1: Defoaming effect The defoaming effect is the key index to evaluate the quality of powder type defoaming agent. A good powder type defoamer should have the effect of fast defoaming and lasting defoaming. In the selection, the measured defoaming time and foam suppression time of the product can be referred to, and these data can directly reflect the defoaming performance of the product. In addition, different processes and environmental factors will also affect the defoaming effect, so it is recommended to test and compare in practical applications. Step 2: Stability The stability of powder type defoamer is very important for its application in the surface treatment industry. The product with good stability can maintain the activity for a long time and play the role of defoaming stably under different process conditions. In the selection, attention should be paid to the physical stability of the product (such as particle size distribution, hygroscopicity, etc.) and chemical stability (such as acid and alkali resistance, high temperature resistance, etc.). These indicators will directly affect the use effect and storage performance of the product. Step 3: Compatibility The compatibility of powder type defoamer with other substances is also a factor to be considered when selecting. Good compatibility can ensure that the defoamer is evenly dispersed in the surface treatment solution, so that the defoamer can play a better role. In the selection, attention should be paid to the compatibility of the product and the surface treatment solution to avoid precipitation, delamination and other phenomena. Step 4: Price Price is one of the factors that must be considered when buying. When selecting powder type defoamer, reasonable selection should be made according to actual production demand and cost budget. Under the premise of ensuring product quality and performance, choosing products with reasonable prices helps to reduce production costs and improve the overall economic benefits.     Part two: Matters needing attention in practical application 1.
