1. General characteristics of Nylon
1. Density of Nylon 6: With the increase of methylene content and the decrease of amide group content in nylon, the crystallinity of nylon decreases and the density also decreases.
2. Crystallinity of Nylon Pa6: Nylon is a semi-crystalline engineering plastic with nodules and non-finished areas. The crystallinity has a great influence on the thermal properties of nylon. nylon
Crystallization has some effect. During injection molding, the mold temperature is high, the melt cooling time is long, and the crystallinity of the product is high. Nylon with high crystallinity has more
High tensile strength, impact strength and heat deflection temperature.
3. The molecular weight of Nylon Pa6 has a great influence on its mechanical properties. The molecular weight of engineering plastics should generally be greater than 20,000.
4. Nylon air permeability: air permeability is an important characteristic of nylon. Nylon has the lowest permeability to oxygen and other gases, so it has excellent barrier properties and is the best choice for dry food
Excellent material for food preservation packaging.
2. The structure and mechanical properties of nylon The repeating unit on the main chain of nylon molecule contains polar amide groups, which can form hydrogen bonds for molecular identification. it is crystalline and molecular
The interaction between nylon is strong, so nylon has high mechanical properties and modulus. As the methylene content in the nylon backbone increases, the mechanical strength and modulus decrease,
And the impact strength increases.
Other ways to increase mechanical strength; The molecular structure has symmetry, and the structure of cyclic and aromatic compounds is introduced in the repeating unit of the main chain. molecular nylon
The amide group of the main chain is a hydrophilic group with water absorption. The smaller the amide group density, the lower the water absorption,
Water absorption of nylon will lead to a decrease in mechanical properties: water absorption of nylon will destroy the hydrogen bond of the molecular part, weaken the intermolecular force, and play a plasticizing role, resulting in a decrease in the strength of nylon
And lower modulus, higher impact strength and larger product size. type.
