The fan is developed for high pressure requirements of the acid production process in the highland areas of western China or in the plain areas, and is mainly used for transporting acid-sulphur dioxide gas. The heart of the impeller is designed to be two-stage compression, which solves the two major problems of compression ratio, corrosion of the sulfuric acid, and strong adhesion that affect product quality.
The fan has the advantages of low rotation speed, comparable compression ratio, simple structure, convenient operation and maintenance, long service life, etc. It is an ideal product suitable for high-pressure acid production process in high altitude areas.
With the rapid development of science and technology, the use of plastics in modern medicine is steadily increasing. Medical devices made from injection-molded plastics help reduce health care costs, infectious diseases and pain management. High-tech polymers are used in medical device prototyping and are often used to create improved prosthetics and devices to reduce the risk of infection. Medical plastic injection molding directly improves patient safety and the ability to save more lives. High-gloss injection molding: the basic process of high-gloss injection molding is to rapidly heat the surface of the mold with high temperature and high pressure steam before injection molding, so that the surface temperature of the molding mold cavity reaches above the glass transfer temperature (TG) of the resin plastic, and then inject the plasticized plastic melt into the closed mold cavity. During the injection phase, the mold temperature is kept constant by high temperature and high pressure steam. After injection molding, stop the air supply, blow out the steam in the tube with the air pressure of the duct, and then inject cooling water to make the mold temperature drop rapidly, until the mold is cooled and opened to take out the product.
