What raw materials does Radmehrplast company use to produce its tanks?

The raw materials used in the production of polyethylene tanks are related to HDPE and MDPE polymers. The grade used in making Radmehrplast tankers is heavy polyethylene 3840 of Tabriz. These materials have good processability, hardness and resistance, and also have the property of being hygienic and food grade.

How are Radmehrplast tanks produced?

The construction and production of polyethylene tanks is generally based on rotational molding technology. Rotational molding or rotomolding in short is one of the processes of forming plastic materials in the form of hollow hollows.

In general, in this method, a certain amount of the raw material of the tank (plastic) is introduced in the form of powder into a mold that is designed in the shape of the final product. This mold is rotated around axes and as a result of the heat applied to it, the polyethylene inside sticks to the walls of the mold and creates a layer on the inner surface of the mold.

The rotation of the mold continues during the cooling phase so that the plastic takes its desired shape and solidifies. When the plastic hardens enough, cooling and spinning are stopped to remove the plastic part from the mold. At this point, the process cycle is repeated again.

How to make sure your tanks are standard?

The engraving of the standard logo on all Radmehrplast tanks confirms the authenticity of this item, however, you can inquire about the code "p. 898465599" from the National Standard Organization.

What are the conditions of warranty and after-sales service of Radmehrplast products and how long does the company guarantee its tanks?

Radmehrplast company guarantees its tanks for up to 10 years and provides after-sales service for its customers for up to 12 years.

Which type of tank is anti-algae?

Multi-layer tanks do not allow sunlight to pass into the tank due to the black middle layer. Radmehrplast company uses raw materials called masterbatch to produce this dark layer, which makes water tankers anti-algae and antibacterial.

Can polyethylene tanks be used to store drinking water and food?

Yes, Radmehrplast tanks are produced from high-quality and sanitary grade raw materials. Single-layer tanks are suitable for use in indoor spaces. Three-layer and four-layer tanks can be used in tropical areas and open spaces and are resistant to sunlight due to having a colored layer. These tanks have the ability to store water for a long time, without changing color, smell and taste. Polyethylene tanks can be recycled at the end of their life, but recycled tanks are not suitable for storing and using drinking water because recycled plastic cannot protect water from the sun and heat. Also, drinking water regulations only allow the use of new plastics, and Radmehrplast has complied with this.

Does the color, smell and taste of the water in the polyethylene tank change?

Algae after decomposition by anaerobic bacteria can cause bad smell, bad taste and change the color of water. Algae growth is also accelerated by the penetration of more light into the tank. Therefore, by placing single-layer tanks in darker and less light environments or using multi-layer tanks, you can prevent the growth of algae in the tank as well as changing the color, smell and taste of water.

What is the difference between horizontal and vertical tanks in terms of quality?

Radmehrplast's horizontal and vertical tanks have differences in terms of design, weight and price, but in terms of quality and production process, they are not different from our other products.

What is the difference between metal tanks and polyethylene tanks?

One of the differences between metal tanks (galvanized) and plastic tanks (polyethylene) is that in metal tanks, due to the continuous contact of water with the tank, especially its welded points, it causes the materials to decompose and poison the water or liquid inside the tank. But due to the hygiene of the raw materials used in the construction and production of plastic tanks, this is not the case and the water is not poisoned.

Why are horizontal tanks more expensive than vertical tanks?

Horizontal tanks are more expensive than vertical tanks due to having a base, more weight and using more raw materials.

How to distinguish a single-layer tank from a multi-layer tank?

One of the ways to identify single-layer tanks from multi-layer tanks can be investigated according to the light transmission. For this, three methods are suggested, which we will discuss further:

1. In the three-layer tank, it is not possible to see the shadow due to the absence of light. Therefore, you can place your hand on the outer surface of the tank to distinguish whether it is single-layer or three-layer. If the tank is single-layered, you can see the shadow of your hand from the inside due to the light passing through, but if the tank is multi-layered, it is not possible to see the shadow of your hand.
