Characteristics of plastic ready board box:

 

1. Good electrical performance

 

PC materials used for manufacturing electrical products have the following electrical properties:

 

Insulation resistance (immersed in water for 24h): 1.0x10 m Ω

 

Arc resistance: 180s

 

Electric leakage resistance index: 600V

 

The insulation protection and anti creepage indexes meet the relevant standards of DIN / VDE. This material not only has excellent electrical insulation, but also can maintain good dielectric properties at high frequencies. It is not subject to electromagnetic effects and does not reflect electromagnetic waves. These properties are far from that of non-metallic materials.

 

2. Chemical corrosion resistance

 

PC material has good corrosion resistance to acid, dilute alkali, salt, organic solvent and seawater, while metal material is not resistant to acid and seawater.

 

3. Light weight and high strength

 

Specific strength and specific modulus are one of the indicators to measure the bearing capacity of materials. The specific modulus of PC material is equivalent to that of steel, but its specific strength can reach 4 times of that of steel.

 

4. Good fatigue resistance

 

The tensile strength of PC material is slightly better than that of steel, and the fatigue resistance limit of steel and most metal materials is 40% - 50% of its tensile strength, while the fatigue resistance limit of fiber reinforced composite materials is generally higher than this value, and the highest can reach 70% - 80%.

 

5. Notch sensitivity

 

When the component is overloaded and a small number of fibers are broken, the load is quickly distributed on the undamaged fibers to reach the mechanical balance again. This is incomparable with metal components.

 

6. Low thermal conductivity and low expansion coefficient

 

When there is a temperature difference, the thermal stress generated is much smaller than that of metal.

 

7. Excellent UV resistance and aging resistance

 

Among non-metallic materials, PC material has excellent anti-aging performance. The anti-aging performance test shows that the maximum aging thickness of the surface is less than 50% in 20 years in different places and different climatic zones μ mThe minimum thickness of most boxes is 5mm, which is less than 1% of the box thickness, so it has no obvious impact on the mechanical performance of the box. Lingwai has adopted a special UV resistant surface treatment process to further enhance its aging resistance.

 

8. Long service life

 

The service history in Europe can prove that its service life is at least 20 years; The simulated aging test shows that its service life is more than 20 years, far exceeding that of traditional materials such as metals. Some companies producing pipes with such materials also claim that the service life of their pipes is 50 years.

 

9. Flame retardant, smokeless and non-toxic

 

This material is a kind of flame retardant material, with flame retardancy grade of fv0 (the highest level of non-metallic materials), smoke emission level of 15 (smoke emission level 1-100) under high temperature ignition, non-toxic smoke, and toxicity level of za1 (quasi safety level 1).
