Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical industry, in particular to a nylon 6 slice viscosity increasing device. Background Art
[0002] Nylon 6 is a high-viscosity product used in the field of engineering plastics. Nylon 6 is a thermoplastic with excellent performance. It is widely used in automobiles, mechanical electronics, daily products, chemical building materials, etc. It is also used as the basis of modified resins. In recent years, with the development of the automobile, machinery, and electronics industries, the development and application of nylon 6 has developed more and more rapidly, and there are more and more product varieties. At present, the production of nylon 6 is mainly concentrated in developed countries, and a large number of nylon 6 resins need to be imported. Domestic nylon 6 is mainly fiber-grade products. This year, attention has been paid to the development of nylon 6, but it is far from meeting market demand. In the production of nylon 6, nylon 6 needs to be thickened, and a nylon 6 slice thickening device is required for thickening.
[0003] When thickening nylon 6, existing devices mostly use solid-phase thickening amplification. The specific method is to heat nylon 6 to a temperature below its melting point and above its glass transition temperature, usually between about 10-40°C below the melting point, and then take away small molecular products with nitrogen to continue the polycondensation reaction and increase the viscosity. The heating method for nylon 6 is mostly to heat nitrogen and then use high-temperature nitrogen to heat nylon 6. However, during actual heating, the high-temperature nitrogen contacted by nylon 6 near the outlet is higher in temperature than that contacted by nylon 6 far from the outlet. As a result, when the nylon 6 far from the outlet is heated to a suitable temperature, the temperature of nylon 6 near the outlet is already higher than the melting point, which causes the nylon 6 slices to melt and stick together, which is inconvenient to use.
