  FRP natural gas tank insulation box is molded by SMC unsaturated polyester glass reinforced fiber
  1. Composition of FRP natural gas box insulation box material
  The main components of the cabinet are divided into two materials: DMC.SMC. The composite material consists of two parts: a matrix-polyester resin; a reinforcing material (SMC for short), so it is also called a fiber-reinforced polyester material. The fiber-reinforced unsaturated polyester is a composite material based on an unsaturated polyester resin. This material has an insoluble and infusible three-dimensional network structure, which has become a high-performance engineering material through functional filler modification and special fiber reinforcement.
  Second, the characteristics and advantages of the box material
  1, good electrical performance
  Fiber reinforced polyester materials used in the manufacture of electrical products have the following electrical properties:
  Insulation resistance (water immersion 24h): 1.0x10 MΩ
  Arc resistance: 180s
  Resistance to tracking index: ≥600v

  Insulation protection and anti-climbing indicators comply with DIN/VDE related standards. This material not only has excellent electrical insulation, but also maintains good dielectric properties at high frequencies, is immune to electromagnetic effects, and does not reflect electromagnetic waves. These properties are far from comparable to metal materials.

  2, chemical corrosion resistance
  Fiber reinforced polyester materials have good corrosion resistance to acids, alkalis, salts, organic solvents, seawater, etc., while metal materials are not resistant to acid and seawater.
  3, lightweight and strong
  Specific strength and specific modulus are one of the indicators for measuring the load carrying capacity of a material. The specific modulus of a fiber reinforced polyester material is comparable to that of steel, but its specific strength is four times that of steel.
  4, good anti-fatigue performance
  The tensile strength of fiber reinforced polyester is slightly better than that of steel. The fatigue limit of steel and most metal materials is 40%-50% of the tensile strength, while the fatigue resistance of fiber reinforced composites is generally higher than this. A value of up to 70% -80%.
  5, gap sensitivity
  When the component is overloaded and there is a small amount of fiber breakage, the load is quickly distributed on the unbroken fibers to reach the mechanical equilibrium again. This is not comparable to metal components.
  6, low thermal conductivity, small expansion coefficient
  The thermal stress generated when there is a temperature difference is much smaller than that of metal.

      7. Excellent Ultraviolet Resistance and Aging Resistance

      Fiber reinforced polyester materials have excellent anti-aging properties in non-metallic materials. The anti-aging test shows that the maximum aging thickness of the surface is less than 50 micron in 20 years, depending on the location and climate zone. The minimum thickness of most boxes is 5 mm, which is less than 1% of the thickness of boxes, so there is no obvious influence on the mechanical properties of boxes. The company has adopted a special anti-ultraviolet surface treatment process, which strengthens its aging resistance.

      8, long service life

     European service history can prove that its service life is at least 20 years, and 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 that make pipes from such materials also claim that their service life is 50 years.

     9, flame retardant, smokeless, non-toxic

      This material is a kind of flame-retardant material. Its flame-retardant grade is FV0 (the highest grade of non-metallic materials). Under high temperature burning, the smoke emission level is 15 (smoke level 1-100). The smoke is non-toxic and the toxicity level is ZA1 (quasi-safety level 1).

      Because SMC composites belong to thermosetting composites, their recycling value is low, which effectively prevents the case from being stolen. Therefore, the new SMC composite low-voltage distribution box with non-metallic case is specially used for power distribution network in outdoor public places, especially for industrial and mining enterprises, residential areas and high-rise buildings. It has good insulation, environmental protection, flame retardant, corrosion resistance, more than five times longer than metal materials, and also has sunscreen and radiation resistance. It also has the characteristics of heat insulation.
