According to Liu Xianqiu, secretary general of the China Film Industry Association, in terms of technological innovation, China has made major breakthroughs in ultrafiltration, microfiltration and reverse osmosis. The original production of reverse osmosis membranes has always been a blank space. At present, at least three domestic companies have been able to achieve localization and have achieved the bulk export of products. Microfiltration membrane and ultrafiltration membrane technology have reached the world advanced level, are widely used in municipal engineering and sewage treatment projects, and has formed a group of more influential domestic brands. In addition, the gas phase film and inorganic film technology have also been greatly improved, and show a broader application prospects.
Another sign of the maturity of China's membrane and water treatment technologies is that many domestic companies are not willing to stay on the production of membrane and membrane accessories, but also can systematically contract water treatment projects. China Bluestar Beijing Cleaning Company is in the domestic pharmaceutical industry in recent years. One of the outstanding general contractors in the field of beer and food, metallurgy, municipal engineering and other areas, its membrane and water treatment specialization company enjoys a good reputation in the industry.
Liu Xianqiu said that the direct cause of the advancement of China's membrane and water treatment technology is the sustainable development and the implementation of the national policy of circular economy. The market demand has effectively driven the drive chain of application and industry, industry and scientific research.
Pulverizers are machines that pulverize large solid materials to the required size.
According to the size of the crushed material or the crushed material, the mill can be divided into coarse crusher, medium crusher, fine mill and superfine mill. There are four kinds of external forces applied to the solid in the grinding process: pressing, cutting, impact and grinding. Press rolling is mainly used in coarse and medium crushing, suitable for the crushing of hard materials and bulk materials. Shearing is mainly used in fine crushing, suitable for the crushing of ductile materials. Impact is mainly used in medium crushing, fine grinding, ultrafine grinding, suitable for crushing brittle materials. Grinding mainly in fine grinding, ultrafine grinding, suitable for small pieces and fine particles.
The crusher makes use of the high speed relative motion of the movable tooth plate and the fixed tooth plate, so that the crushed object can be crushed by the comprehensive action of tooth impact, friction and the impact between the materials. The crusher is suitable for crushing Chinese herbs, precious medicinal materials, ores and chemical raw materials in small batches in various varieties, alloys, metallurgy, geology, scientific research and other units.
The pulverizer machine has the advantages of simple structure, solid, stable operation and good crushing effect. The pulverized material can be discharged directly from the grinding chamber of the main machine. The particle size can be obtained by replacing the mesh screen with different aperture. The powder collecting chamber adopts the completely closed silencer structure, which can effectively reduce the working noise. In addition the machine is all stainless steel. The inner wall of the casing is machined to achieve smooth surface, which changes the phenomenon of rough inner wall and powder accumulation of the previous models, so that the production of drugs, food, chemical industry and so on is more in line with national standards and meet the requirements of GMP.
