The polyacrylate is easily soluble in acetone, ethyl acetate, benzene and dichloroethane, and is insoluble in water. Polyacrylate can form a glossy and water-resistant film with strong adhesion, no peeling, flexibility and elasticity at room temperature, good weather resistance, but low tensile strength. Can be used as a high-grade decorative coating. Polyacrylate is adhesive and can be used as a pressure sensitive adhesive and a heat sensitive adhesive.
Polyacrylate drying equipment works:
The air is filtered and heated into the air distributor at the top of the dryer, and the hot air enters the drying chamber in a spiral shape evenly. The liquid is sprayed into a very fine misty liquid droplet through a high-speed centrifugal atomizer at the top of the tower body, and it can be dried into a finished product in a short time by cocurrent contact with hot air. The finished product is continuously discharged from the bottom of the drying tower and the cyclone, and the exhaust gas is evacuated by the w fan.
Polyacrylate drying equipment advantages:
The centrifugal spray drying equipment has good uniformity, fluidity and solubility, and the product has high purity and good quality. The production process is simplified and the operation control is convenient. For liquids with a moisture content of 40-60% (up to 90% of special materials), the products can be dried into powdered products at once, without pulverization and screening after drying, reducing production processes and improving product purity. The particle size, bulk density and moisture of the product can be adjusted within a certain range by changing the operating conditions, and the control and management are very convenient.
1. The drying speed is fast, the surface area of the liquid is greatly increased after atomization, and in the hot air flow, 95%-98% of the water can be evaporated in an instant. It takes only 5-15 seconds to complete the drying time and has the characteristics of instantaneous drying.
2. The material completes the drying process in a short time, adapts to the drying of heat sensitive materials, and can maintain the color, fragrance and taste of the materials.
3. The special air separation device reduces the resistance of the equipment and effectively provides the treatment air of the dryer.
4, product dispersibility, fluidity, solubility, product size, looseness, water can be adjusted within a certain range
5, the production process is simplified, suitable for continuous control of production, containing 40-90% of the liquid liquid, once dry into powder, reduce crushing, screening and other processes to improve product purity.
