3. at elevated temperatures. maintaining its mechanical properties
disadvantages:
1. below 0 ℃ easy to become brittle
2. poor weather (the minimum temperature in most parts of the northern winter may be lower than this)
nylon tripod: nylon 66 (PA66 representation ) usually have regular products stand just below the mark; chemical formula: (CH 2) 5 NHCO
advantages:
1. polyamide strength above all varieties
2. larger than the yield strength of nylon 6 and nylon 610, rigid
3. turn over a wide temperature range within the still high strength, toughness, rigidity and low friction coefficient
4. oil and a number of chemicals and solvents
5. good wear
shortcomings :
1.
2. hygroscopic high impact strength in a dry environment to reduce
3. molding process difficult to control
can be seen from the above, their respective characteristics, nylon, is ideal for the manufacture of Legs materials, climatic adaptability.
