According to Global Plastic Network, 88% of nylon 66 is processed into various parts by injection molding, and 12% of nylon 66 is processed into corresponding products by extrusion blow molding.
I. Characteristics of nylon products:
1 is a self-extinguishing material with good compression, wear resistance and heat resistance, which is widely used in automobile parts, power and electronic devices.
2. It has high mechanical strength, and its self-lubricating performance is second only to PTFE (PTFE has the best self-lubricating performance because of its molecular characteristics and polymer structure). It is often used in precision gear parts.
3, excellent oil resistance, soluble in phenol and formic acid, good chemical stability, adding carbon black can improve its weather resistance, and its application in machinery industry should not be underestimated.
As mentioned above, nylon 66 is widely used in several fields: automobile field, electronic appliance field (including precision instrument field), machinery industry field and so on. Although Bianxiao has no specific waste of nylon products, people in the industry are well aware of its current accumulation. Today's society calls for sustainable development and environment-friendly development. Because of the following characteristics, nylon recycled materials are naturally widely used in industry.
2. Nylon 66 is widely used in many fields.
1.
High mechanical strength, good toughness, high tensile and compressive strength. The specific tensile strength of nylon recycled material is higher than that of metal, and the specific compressive strength is equivalent to that of metal, but the rigidity is not as good as that of metal. The tensile strength is close to the yield strength, which is more than twice that of ABS. It has a strong absorption capacity for impact and stress vibration, and its impact strength is much higher than that of ordinary plastics and better than that of acetal resin.
2.
Outstanding fatigue resistance, can still maintain the original mechanical strength after repeated bending. PA is often used in occasions with obvious cyclic fatigue effect, such as common escalator handrails and new plastic bicycle rims.
3. High softening point and heat resistance (such as nylon 46, high crystalline nylon has high thermal deformation temperature and can be used for a long time at 150℃. After PA66 is reinforced with glass fiber, its thermal deformation temperature reaches above 250 degrees).
4.
Smooth surface, low friction coefficient and wear resistance. As a movable mechanical part, it has self-lubrication and low noise, and can be used without lubricant when the friction effect is not too high; If you really need lubricants to reduce friction or help dissipate heat, you can choose water, oil, grease, etc. Therefore, as a transmission part, it has a long service life.
5.
The recycled nylon material is corrosion resistant, very resistant to alkali and most salt solutions, and also resistant to weak acids, engine oil, gasoline, aromatic compounds and general solvents. It is inert to aromatic compounds, but not resistant to strong acids and oxidants. Corrosion resistance of gasoline, oil, grease, alcohol and weak alkali, and good anti-aging ability. It can be used as packaging material for lubricating oil, fuel, etc.
6. Self-extinguishing, non-toxic, tasteless, good weather resistance, inert to biological erosion, good antibacterial and mildew resistance.
7.
The supply of nylon recycled materials has excellent electrical properties. Nylon has good electrical insulation, high volume resistance and high breakdown voltage, and can be used as power frequency insulation material in dry environment or even high humidity environment.
8. The product is light in weight, easy to dye and easy to form. Because of its low melt viscosity, it can flow quickly. Mold filling is easy, and the solidification point is high and fast after mold filling, so the molding cycle is short and the production efficiency is high.
