Summary of high shear mixing emulsifying machine

1. The history of high shear technology in the coatings industry.
The application of high shear technology in coating production process has been widely used in Europe and America as early as the 1980s. The technology was initially applied in the cosmetic production process (mainly to solve dispersion and grinding), and then gradually developed into the coating production process. At that time, experts in the paint industry generally believed that such a sophisticated cosmetic equipment used in the production of coatings whether there was excessive quality problems, and the actual application found that the fineness of the coatings not only as expected to be substantially reduced, the gloss of the coatings, covering rate, adhesion also improved, so in Europe and the United States coatings line There is a saying circulating in the industry that "ordinary coatings come from grinders, high quality coatings come from high shear." However, after this technology spread to China, because the imported equipment is very expensive and people do not require high quality (fineness) of the coating, it can not be popularized and applied. No wonder, when foreign equipment manufacturers promoted their high shearing equipment in China, they once made such a sigh: When the electric light was invented, you still insisted on using kerosene lamps?
2. The current situation of high shear coating technology in China
As a scientific and technological enterprise in the domestic chemical equipment manufacturing industry, Grimald has invested a lot of manpower and material resources in order to promote the traditional backward production process in China, and has carried on the unceasing technical research and development. As a technological innovation, the difficulty does not lie in technical problems, but in changing people's stereotyped traditional thinking and accepting new ideas, new technologies and new concepts. It should be said that Gsmith will be high shear technology applied to coatings equipment and successfully applied to coatings manufacturers, is extremely prudent and rigorous. Gsmith organized a large number of technical experts to engage in research, through cooperation with research institutes, after numerous pilot, pilot and continuous improvement, eventually make it a mature technology to market.
Grimm's coatings equipment set off a storm of technological innovation in China, is attracting more and more enterprises to apply. These companies are also very thoughtful before applying them, but why are they willing to accept this new thing, new technology? As a saying goes, good things are always attractive. Because of its excellent technology and strict production process and quality management, the coating equipment is incomparable with traditional equipment in terms of technology, quality and efficiency.
3. The future of high shear technology in domestic coatings industry.
At present, for this new technology, in the paint industry, some enterprises in the concept of difficult to reverse is very normal, conservatives believe that sand grinding technology has been used for hundreds of years, more reliable, and reluctant to update, innovators personally experience the advantages of high shear technology, but because the market competition is very fierce, external.  Unwilling to make public.
Although McMayer has been committed to vigorous publicity and promotion, but McMayer knows that to thoroughly improve the backward process of domestic paint production, still need to do a lot of meticulous work.  Grimm has reason to believe that the next decade will be a period of quality competition for coatings, but also a good time for Grimm to give full play to its advantages, the traditional sand grinding coatings production process will eventually be completely replaced by high shear technology!
4. Technical analysis of high shear process and sand grinding process.
The traditional disperser, grinder and filter have been used in the production of coatings for hundreds of years. Its working principle is to mix the solid materials and various liquid materials evenly by disperser, but the disperser can not complete the emulsifying function. After processing by disperser, the material will be delaminated in a certain time, so it is necessary to use disperser. The material is refined to the U grade fineness by grinding machine. On the one hand, the appearance of the material is exquisite and the quality of the finished product is improved. On the other hand, the refined insoluble material is easier to be emulsified by the action of active agent (one is hydrophilic group, the other is lipophilic group). The filter is completely used for grinding media, which must be filtered and purchased. High shear technology has fundamentally solved the problem that different chemical processes need to be completed by multiple processes. The key of high shearing technology is the shearing head of stator and rotor. The negative pressure is formed by the high-speed rotation of the rotor. The material is forced to be inhaled into the stator cavity (for mixing) and sprayed out of the stator hole by centrifugal force along the radial direction. The extremely precise clearance between the stator and rotor ensures that the fineness of the material being cut by the quilt reaches the level of um. Of course, the distribution range of the material diameter may be wide or narrow. The key factor determining the distribution range of the material diameter is whether the shearing times of the material being processed in the container are uniform or not. This is a technical problem. It has been satisfactorily solved by adopting high shear emulsifying dispersion, cycling treatment of horizontal grinding mill, static mixer, etc.
The advantages of Grimmax high shearing equipment are obvious. It not only saves the tedious process of traditional equipment, improves the production site environment, reduces labor intensity, greatly improves production efficiency, but also greatly improves the quality of coating products. I believe you can fully realize this and see the broad prospects of this new and high technology applied to the coating industry.
