Customer type
1. Customer information: The Indonesian Institute of Ceramics is a professional research institute engaged in the research of inorganic non-metallic materials, researching special glass, technical ceramics, artificial crystals, quartz fibers, new energy-saving electric furnaces, ultra-fine functional powder materials and heating elements Etc. The original foaming agent can not play an effective role in the effect, so it is necessary to find a better qualified manufacturer.

3. Customer requirements: it must be soluble in water, and can maintain the function of defoaming and suppressing foam under the conditions of high temperature, strong acid and alkali, high shear force and high pressure.
Principle and analysis of defoaming
1. Analysis of the cause of blistering:
The glass industry defoamer is foaming in the collection tank because the liquid foams when there are impurities. Surfactants such as cutting fluid will also foam when the glass is cut, and the surfactants will also foam when the glass is cleaned.
2. The hazards of blistering:
Foam can affect production, and also lead to defective products or quality problems.
3. Analysis of defoamer solutions for glass industry
Foams in the glass industry are inherently extremely unstable, but they can hardly be burst due to the foam stabilizing effect of the foam promoter.
Defoaming principle of Nanhui glass industry special defoamer:
1. The defoamer can be used to reduce the local surface tension of the bubble film, which causes the bubble to burst;
2. The defoamer can promote the membrane to drain, thus causing the bubble to burst;
3. The hydrophobic solid particles will attract the hydrophobic end of the surfactant in the foaming system, and the hydrophobic solid particles will become hydrophilic particles and enter the water phase to cause the foam to burst;
4. The defoamer can damage the elasticity of the film and cause the bubble to burst;
5. The impact of the expansion effect of the defoamer causes the bubbles to burst;
6. Make the foam-promoting surfactant compatibilize and cause the bubbles to burst;
7. The electrolyte collapses the surfactant double layer and the bubbles burst;
Cleaning and foaming solution
According to the needs of the experiment, it is a strong acid-resistant defoamer, and the foam should be broken quickly on the surface of the foam, so it is ideal to use a defoamer with excellent dispersibility and fast solubilization. If the foam is high, a powder-like defoamer Agent is also a good choice.
Industrial characteristics of glass defoamer
The glass industry defoamer is compounded by special modified polyether and fluorine-containing raw materials through a special process. It is very easy to dissolve in water. It is especially suitable for the existence of high temperature, strong acid and alkali, high shearing force and high pressure. Continue to keep defoaming and suppressing foam. It has excellent high temperature resistance, acid and alkali resistance, no floating, no oil floating; it can be widely used in the elimination and suppression of various harsh systems in a wide temperature range.
1. It has strong defoaming and anti-foaming power, with a small amount, and does not affect the basic properties of the foaming system.
2. Good heat resistance, chemical stability, non-corrosive, non-toxic, no adverse side effects, non-flammable, non-explosive.
3. Its performance is comparable to imported products, and the price is more obvious.
