Axle Sleeve high polymer chemistry

Nylon is the United States of America outstanding scientist Carothers (Carothers) and under the leadership of a research team developed, is the world's first composition of the fiber. The appearance of nylon to make the appearance of textiles, its composition is composed A major breakthrough in the fiber industry, polymer chemistry is also an important milestone, the following by the company editor for everyone:

Nylon (Nylon), the English name polyamide (referred to as PA), is the molecular chain rich in repeat amide gene - [NHCO] - the general name of the thermoplastic resin, including aliphatic PA, fat a aromatic PA good aromatic PA. Aliphatic PA species, large output, widely used, the name of the monomer by the composition of the number of carbon atoms in detail.

Nylon has many characteristics, therefore, in the automotive, electrical equipment, mechanical structure, transportation equipment, textiles, paper machinery, etc. are widely used. With the miniaturization of the car, the high functionality of electrical and electronic equipment, the acceleration of the process of lightweight mechanical equipment, the demand for nylon will be higher and greater. In particular, nylon as a structural data, its strength, heat resistance, cold resistance and so put forward a high demand.

Nylon inherent defects are also an important factor in the use of constraints, especially for the PA6, PA66 two kinds of species, and PA46, PAl2 and other analogy has a strong price advantage, although some features can not be satisfied with the needs of career development. Therefore, it is necessary for a certain area of use, modified, and improve its function to expand its use of the field. Because PA strong polarity characteristics, hygroscopicity, poor scale stability, but can be modified to improve.

Nylon tube is not only the same choice of trademark nylon materials extruded various specifications of the pipe and the use of caprolactam information casting hard thick-walled nylon tube. This entry examines the most commonly used nylon hose. Nylon is the United States outstanding scientist Carothers (Carothers) and under the leadership of a research team developed, is the world's first synthetic fiber. The emergence of nylon to make the face of a new look, its synthesis is a major breakthrough in the synthetic fiber industry, but also an important milestone in polymer chemistry, the following editor to continue to introduce:

Polyamide (Nylon), the English name Polyamide (referred to as PA), is the main chain containing repeating amide group - [NHCO] - the general term for the thermoplastic resin. Including aliphatic PA, fat-aromatic PA and aromatic PA. Among them, the aliphatic PA varieties, large output, widely used, the name of the monomer by the specific number of carbon atoms.

October 27, 1938 officially announced the world's first synthetic fiber was born, and the polyamide 66 this synthetic fiber named nylon (Nylon).

Nylon has a lot of features, therefore, in the automotive, electrical equipment, mechanical structure, transportation equipment, textiles, papermaking machinery, etc. are widely used. With the miniaturization of the car, the high performance of electrical and electronic equipment, machinery and equipment to speed up the process of light, the demand for nylon will be higher and greater. In particular, nylon as a structural material, its strength, heat resistance, cold resistance and so put forward a very high demand. Nylon inherent shortcomings is also an important factor limiting its application, especially for PA6, PA66 two varieties, and PA46, PAl2 and other varieties have a strong price advantage, although some of the performance can not meet the requirements of the development of related industries. Therefore, it is necessary for a particular application area, through the modification, to improve its performance, to expand its application areas. Due to the strong polarity of PA, hygroscopicity is strong, and the dimensional stability is poor, but it can be improved by modification.
