XJY-8205 MQ Resin Powder
Silicone Methyl MQ Resin
The MQ resin has a three-dimensional structure and will be cross-linked with the main body of the defoamer to form a network to avoid the breakage of the main active substances composed of disiloxane and silica , Thereby improving the acid and heat resistance of the defoaming agent, and increasing the defoaming time
The active ingredient of silicone defoamer is silicon paste. Hydrophobic silica particles in silicone paste to form a defoaming agent dispersion in silicone oil to help silicone oil enter into the surface of foam film, reduce insertion resistance of silicone oil drops and foam drainage time. Also, it can increase the depth of foam dispersant inserted on the surface of foam film to improve the ability to destroy the oil-water-air film and accelerate the defoaming speed.
The SI-OH bond of methyl MQ silicone resin with heating conditions can react with the residual Si-OH in dimethyl silicone oil and hydrophobic fumed silica to form an organic polymer with a complex polymer chain structure. This polymer can effectively improve the dispersibility of silica, and further enhance the synergistic defoaming and antifoaming performance of silica and dimethyl silicone oil.
Emulsion type organosilicon defoamer uses two methyl silicone oil as the main raw materials, which is a defoamer emulsifier by adding methyl MQ silicone resin and hydrophobic carbon black. It can be widely used in various industries: food, paper, leather, coatings, environmental management and other aspects of chemical production.

Silicone-based defoamers are widely used in many industrial applications to make chemical processing be improved foam control.
Silicone antifoam or silicone defoamer are widely used in direct or indirect food contact applications throughout all stages of the industrial processes. From large factories and restaurants to home cooking, food packaging and labels, traces of silicone can be found everywhere. Silicone has the advantages of being easy to use, safe operation, no odor, and no impact on food characteristics, making it unparalleled in satisfying the various needs of food processing. They are used in a variety of food and beverage applications to anti-foaming or eliminate existing foam during production.
Foaming issues in food and beverage processing applications can negatively impact efficiency, productivity and cost. Silicone antifoam or defoamers as processing aids are designed to safely and effectively reduce foam problems in a variety of conditions encountered in food and beverage processing. Whether added purely as a liquid or powder or mixed into other compounds or emulsions, silicone antifoams are more effective than organic ones.
1. Food processing: It can effectively defoaming in food processing, and is generally used in the processing of water-soluble food, with stable performance and good defoaming effect.
2. Sugar industry: After the honey is fermented, calcium carbonate needs to be added for neutralization. Foam will be generated during the neutralization process, and a defoamer is needed for defoaming.
3. Fermentation industry: Grape juice will produce gas and foam during the fermentation process, which affects normal fermentation. The defoamer can effectively defoam and ensure the production quality of the wine.
As a direct user textile printing and dyeing factory, we attach importance to the performance of defoamer, confirm the product quality through trial on the machine, and require defoamer: viscosity should not be too high, easy to use, easy to control addition, economical cost, rapid defoaming and long-lasting inhibition of foam. good dispersion, no oil bleaching, no silicon spots, safe and non-toxic, in line with the requirements of environmental protection.
Printing and dyeing auxiliaries companies, a variety of self-produced auxiliaries products, focus on matching, require defoamers: products thick, easy to dilute and compound, products have a long shelf life, products have a high performance-to-price ratio, solve the compounding with auxiliaries, provide technical support.
Traders of dyeing and chemical materials, most of whom have mature users, require defoamers: products with a high performance-to-price ratio, stable product quality, and provide technical support.
The practice has proved that defoamers for textile printing and dyeing should have: rapid defoaming and long-lasting foam inhibition, high-cost performance; good dispersibility, high-temperature resistance, acid and alkali resistance, electrolyte resistance, shear resistance, good compatibility with various dyeing chemicals, no oil bleaching, no silicon spots; safety, non-toxic, in line with environmental requirements; stable quality, suitable viscosity, and concentration, easy to use and dilute; provide timely and effective technical support.
As a new type of defoaming aid, active silicone defoamer has been widely valued in the paper industry. Its defoaming principle is that when a very low surface tension defoamer enters the directional bubble film, it destroys the directional bubble film. The mechanical balance can be achieved to achieve foam breaking and foam control.
|According to physical properties, silicone antifoam agent can be divided into four categories: silicone oil type; silicone oil solution type; silicone oil mixture type; silicone oil emulsion type. In the paper industry, the commonly used silicone oil type defoamer can be either silicone oil type or silicone oil emulsion type. At present, it is mainly silicone oil emulsion type. When silicone oil is emulsified, it is added to the foaming system. It can quickly reduce the surface tension, so it is easy to be adsorbed on the surface of the foam liquid, and the surface film formed by spreading quickly on the liquid surface, because of its low viscosity and low strength, can cause local surface tension imbalance on the foam, thus The liquid film is thinned to rupture to achieve the purpose of defoaming. For emulsion type defoamer, because of its large hydrophilicity, it can adapt to a wide range of pH values, has no adverse effect on sizing, will not produce stains on the paper surface, and can achieve strong foam breaking with low dosage. and anti-foaming effect.
In the silicone oils mixture type, XJY-8205 MQ silicone resin is mixed with a silica-silicone oil system. MQ resin can improve the applicability of this type of defoamer under high-temperature conditions and ensure the performance of the defoamer in a wider temperature range. It will not weaken, and temperature changes in papermaking, such as high temperature, are also common, so the use of XJY-8205MQ silicone resin is largely effective and can meet your demanding applications.
