Organic silicon modified acrylic acid three-stage emulsifier

Water soluble organic silicon modified acrylic resin high-speed disperser, organic silicon modified acrylic resin high-speed disperser, water-based acrylic amino baking paint resin high-speed disperser, single component metal anti-corrosion water-based baking paint resin high-speed disperser, water-based acrylic amino baking paint resin high-speed disperser refers to a dispersion system that disperses insoluble solid particles into a liquid medium. During the dispersion process, it is often necessary to reduce solid particles, which is known as wet grinding or high shear dispersion. Using a SID high shear disperser to input a large amount of energy can achieve our goal.

Water soluble organosilicon modified acrylic resin is a type of modified resin made by reacting polyacrylic acid phenol resin containing active hydroxyl groups with organosilicon oligomers containing active hydroxyl groups (or alkoxyls). It has good physical and mechanical properties. The resin coated on aluminum sheet has an elasticity of Lrnrn after baking at Lsa -20U ℃ for 2 hours. Impact strength SUOi<1 "cm, good water resistance, no foaming, no peeling, and no discoloration after 200 hours of water immersion. Excellent heat resistance and weather resistance. Prepared by reacting silane or siloxane containing methyl methacrylate oxygen group with acrylic acid monomer or intermediate under the action of catalyst. Organic silicon modified acrylic resin is mainly used in paint production, with excellent gloss retention, color retention, resistance to powdering, and good gloss. Widely used for automotive paint, metal plate pre installation (coil material), prefabricated metal plates for construction, and coating of machinery and equipment, as well as for exterior wall coatings. It is mainly divided into two types: room temperature self drying type and drying type. In terms of weather resistance, the drying type is superior to the self drying type.

experimental result：

Performance testing: Four samples were tested in terms of adhesion, hardness, impact, and ethanol resistance. The test results showed that ③ had slightly higher hardness than the other three samples; ①②④ These three samples have roughly the same performance, with sample ④ slightly better in hardness than sample ①②.

Chart analysis: From the above figure, it can be seen that the average particle size of the processed samples in Shanghai is basically the same as that of the small-scale test,

From the distribution interval, the distribution range of ②, ③, and ④ is also basically the same.

From the perspective of particle size distribution, ③ has a high degree of concentration, with the median particle size accounting for 37% of the total, ② and ④ have a median particle size accounting for 30% of the total, and ① has a median particle size of only 8%, with uneven distribution.

Conclusion: ③ The sample was synthesized at National Taiwan Normal University in a synthetic environment with better equipment and rotation speed than other samples. The particle size distribution was concentrated, and the performance was slightly better than other samples. ④ The sample is the main research objective of this test. From the test results, it can be seen that sample ④ is qualified in terms of performance, slightly better than the small-scale sample ② synthesized from feather stones and the pilot sample ①; The particle size distribution is also basically the same as ②. The sample ④ was processed from the sample ①, so the processed result is qualified and effective.

Suggestion: reprocess the pilot sample and check whether the processed experimental results have reproducibility and scientificity. Only then can we better assess the effectiveness of Shanghai's handling.

XRS2000 imported ultra-high shear high-speed emulsifier
The three-stage high shear dispersion machine is mainly used for the production of micro lotion and ultra-fine suspension lotion. Since three groups of dispersion heads (stator+rotor) in the working chamber work at the same time, after high shearing, the lotion drops are more delicate and the particle size distribution is narrower, so the stability of the generated mixed liquid is better. The three sets of dispersing heads are easy to replace and suitable for different process applications. The different models of machines in this series have the same line speed and shear rate, making it very easy to scale up production. It also meets the CIP/SIP cleaning standards and is suitable for food and pharmaceutical production.

High rotational speed and shear rate are important for obtaining ultrafine suspension lotion. According to some industry specific requirements, its shear rate can exceed 15000rpm, and the rotor speed can reach 44m/s. Within this speed range, turbulence caused by shear forces combined with specially developed motors can reduce the particle size range to the nanometer level. The shear force is stronger, and the particle size distribution of lotion is narrower.
