Introduction

If the water quality is bad, the inter tank could be completely corroded in 2~3 years

Stainless steel is not means it can’t be corroded, it is only not easily be corroded. But under the high temperature, the chloride ion and fluoride ion in the water are very active, they could serious hurt the stainless steel inner tank of solar water heater.

Advantages of plastic tank

1. Strong corrosion resistance and long service life.
   High efficiency: Less producing process.
   3. No adherent limescale: Easy to clean.
   4. Good insulation: Low thermal conductivity, good heatretention.
   5. Safety and health: Raw material passed the national tests.

Comparisons between Metal tank and plastic tank

• Metal inner tank:

has to be welded, thus easy to be corroded and leakage

• Plastic tank:

1. produced by NMPP, strong acid and alkali resistance.
   2.double layer composite, solved inner/outertank corrosion and leak.

Some key improvements in the raw material formula as patent:

Tensile Strength increased 17.6% and Flexural Modulus raised about 48%, which means better performance in strength and hardness, reduce the possibility of leak when the pressure increases.

Vicat Softening Temperature increased from 135℃ to 152℃, and Defection Temperature Under Load goes up from 108℃ to 132.3℃, which improve the sustainability in high temperature giving a longer service life.

We didn't sacrifice Charpy Notched Impact Strength to get increase in those four indexes, which is indeed a great improvements.
