؟How to tell the difference between a single-layer tank and a three-layer tank

In order to distinguish between a single-layer tank and a three-layer tank. This difference can be seen from the upper part of the cut of the tank door
Another way to detect the presence of a black layer on the wall of the tank and the effect of blackness is to put the camera lid inside the tank
After placing the camera by closing the tank door in a place with a lot of sunlight or artificial light. Light penetration or lack of penetration is easily seen

First layer:
White color (or desired color) – with additives resistant to sunlight – resistant to heat and cold temperature changes – white color reduces heat absorption from sunlight and maintains water temperature (color and thickness of this layer according to the need) And the customer’s taste can be changed.

Second layer:
Black color – resistant to the growth of bacteria and algae – against the ultraviolet rays of the sun and completely hygienic.

Third layer:
A combination of polyethylene and foam resistant to the penetration of weather, heat and cold factors – thermal insulation.

Fourth layer:
The white color of the internal-hygienic layer, suitable for storing liquids such as pharmaceuticals-food grade layer and without any reaction with the stored materials inside the tank.

؟Why is the price of a three-layer tank higher than a single layer

The difference in the price of a single-layer and three-layer tank is only in the small amount of polyethylene used in the inner layer.
Because the black color used in the middle layer dominates the white color. Therefore, it is necessary to maintain the inner layer of the uniform and white color. The inner layer should be thicker.
Another reason is that the existence of the black layer causes multiple production methods and increases the production time.Does the black layer have a

؟role in the strength of the polyethylene tank

No, the black layer usually does not have a role in increasing the strength or increasing the thickness of the tank. The black layer prevents the passage of light into the tank to prevent the growth of algae that changes the color, smell, and taste of the water.
