Nylon is the outstanding American scientist Carothers (Carothers) and its leadership under a scientific research group developed, is the world's first synthetic fiber. The appearance of nylon has changed the appearance of textiles. Its synthesis is a major breakthrough in synthetic fiber industry and an important milestone in polymer chemistry.
Nylon, English name polyamide (referred to as PA), is a thermoplastic resin containing polyamide gene -[NHCO]- on the main chain of the molecule. Including aliphatic PA, aliphatic aromatic PA good aromatic PA. Among them, aliphatic PA has many varieties, large yield and wide application. Its name is determined by the specific number of carbon atoms of synthetic monomer.
Nylon has many characteristics, so it is widely used in automobile, electrical equipment, machinery, transportation equipment, textile, papermaking machinery and so on. With the miniaturization of automobile, the high performance of electronic and electrical equipment and the acceleration of the process of lightweight mechanical equipment, the demand for nylon will be higher and greater. Especially nylon as structural material, its strength, heat resistance, cold resistance and other aspects put forward high requirements.
The inherent shortcomings of nylon are also important factors limiting its application, especially for PA6 and PA66, which have a strong price advantage compared with PA46 and PAl2, although some properties can not meet the requirements of the development of related industries. Therefore, it is necessary to expand its application field by modifying and improving its performance. Due to the characteristics of PA strong polarity, hygroscopicity is strong and dimensional stability is poor, but it can be improved by modification.
Nylon pipe is a kind of rigid thick wall nylon pipe which is extruded by different grades of nylon material and cast by caprolactam material. This entry mainly introduces the most commonly used nylon hose.
