The defoaming agent and industrial production are connected closely. The foam produced in industrial manufacturing would seriously impact the subsequent manufacturing procedure, and the utilization of defoaming agent could efficiently remove and suppress the foam production. Therefore defoaming is highly important for production in industries.
What is the Basis of the Selection of Water Defoamer?
People broadly use defoamers, and there are different types of defoamers that almost every wholesale defoamer supplier sells in the market for defoamers. Water defoamers have a market share of over sixty percent, so the question that arises is how to choose the proper commodities among several water defoamers another question might come to your mind is that how to get skilled at adding a quantity of defoamer to treat waste. Selecting a bad defoamer not only results in the waste of money and time but also fails to find the solution to the bubble problem. It would even impact the water treatment system’s benign operation.
How to Select Water Defoamer to Treat Water
Water defoamer must be tough or insoluble to soften in foam solution to eliminate foam. It must be concentrated on a bubble film, and the foam suppression’s state must always be kept in such a state. In order to attain the best impact, its active component’s molecule should be weak hydrophilic and robust hydrophobic, and the hydrophilic-lipophilic balance must be controlled in the 1.5 to 3 range. Thus, the water defoamer is supersaturated inside the foaming solution. Just whenever it is insoluble, it can simply attain supersaturation. When the water defoamer is insoluble, it is simple to gather a liquid-gas interface, it is simple to concentrate on the bubble membrane, and it could perform at a lower concentration.
The defoamer’s surface tension needs to be lower than the surface tension of the foaming solution. Only when the water treatment defoamer’s surface tension is lower than the foaming solution’s surface tension the defoamer molecules could be immersed and extended on the bubble membrane. It should be noted that the foaming solution’s surface tension is not the solution’s surface tension, but it is the foaming solution’s surface tension.
The defoaming agent for the treatment of water requires a specific affinity level with the foaming fluid because, in the procedure of defoaming, there is really a rivalry between the foam s collapse rate and the foam formation rate, so the water treatment defoaming agent should rapidly disperse in the foaming fluid so as to perform a role in the bigger range of foaming fluid rapidly. Thus, in order to rapidly diffuse the defoamer, the defoamer’s active parts should have a specific level of attraction with the foaming solution. The defoamer’s active solution is extremely near to the foaming solution, which would soften and be tough to disperse. Only when the closeness is proper would the impact be good. This is a water treatment foaming agent’s technical point.
There should be no chemical reaction between the foaming solution and the defoamer. If the defoamer responds with a foaming solution, on the one hand, the defoamer will lose defoaming impact. On the other hand, it might produce dangerous materials which would impact the growth of microbes and the water treatment system operation.
The defoamer’s volatility in the treatment of water should be small, and the foam suppression’s time should be long.
Why Must People Utilize Water-Based Defoamers?
Defoamers play an important role in assuring foam does not impact the quality of procedures and processes during industrial uses. These defoaming agents are available in several to suit various operations encompassing water-based, surfactant-based, and oil-based. This blog section emphasizes water-based defoaming agents, describing what they are and what advantages they provide.
Description of Water-Based Defoamers
Water-based defoaming agents are an environmentally friendly, effective, and efficient solution to control the build-up and formation of foam. That is why employees across a broad range of processing sectors utilize them to meet their foam-controlling requirements. As suggested by its name, water-based defoaming agents use water in a continuous stage or as a carrier. They usually consist of sixty to ninety-five percent water. Several of them are technically oil-in-water emulsions and thus consist of some type of oil or fat. Their examples are vegetable oils, mineral oils, and synthetic or natural waxes. By utilizing water as their carrier and showing these active ingredients in an emulsified type, these defoaming agents can more simply dissolve into water and water-based procedure medium and efficiently suppress foam.
Benefits of Water-Based Defoaming Agents
Compared to the rest of the kinds of defoamers, water-based defoamers provide many benefits.
Water is the least costly ingredient that defoaming agent makers can add to a formulation. The water-based defoaming agents could sometimes be composed of by-products of other production applications. This has made them simpler and cheaper to manufacture.
They simply dissolve in water-based solutions and water to offer foam deaeration and suppression. Apart from that, they usually do not contribute to a deposition that could result in the malfunctioning of the equipment, quality issues, or product damage.
They are suitable for utilization in a broad range of operations and industries, from paper processing to wastewater treatment. They can do defoaming across different temperatures, usually up to one hundred and sixty Fahrenheit and pH levels.
Ease of Using
They often need a minimum manufacturing machine to dilute to lower concentrations. Thus, they are simpler to use.
Several water-based defoaming agents do not consist of dangerous parts, and they are inclined to have no little impact on the atmosphere. In addition, several variations could be considered biodegradable, thus permitting their utilization in more environmentally-sensitive uses.
Industrial uses of water-based defoaming agents
As far as the utilization of water-based defoaming agents is concerned, paper manufacturers first utilized these defoaming agents in the paper industry. Since then, manufacturers have utilized them in several other sectors due to their biodegradability, Eco-friendliness, low cost, and other beneficial qualities. Nowadays, apart from the paper industry, manufacturers use these defoaming agents in the following applications and industries
- Wastewater treatment
- Water treatment
- Manufacturing of chemicals
- Beverage and food
- Components cleaning
