Bulky and ultra-bulky polyethylene tanks are used to store and store water and other liquids compatible with polyethylene. These tanks are produced in various shapes, sizes and volumes. One of the best features of polyethylene tanks is that they are more affordable than other tanks made of other materials, and they are easy to prepare and use. These bulky polyethylene tanks are compatible with most liquids and are used in every industry from agriculture to industrial and semi-industrial businesses and as water storage for large residential complexes. Due to the flexible materials used in the construction of polyethylene tanks and their manufacturing method, various shapes can be given to them according to different uses.
Another popular and widely used feature of bulk and ultra-bulky polyethylene tanks is that they can be produced colorless so that the amount of liquid inside them can be easily seen. This feature has caused many different industries not to use metal tanks and other types of tanks and to switch to bulk and ultra-bulky polyethylene tanks. Also, the high volume that these polyethylene tanks can have is another widely used feature for industries that deal with high volumes of liquids. Polyethylene tanks can be 10,000 liters, 20,000 liters and even more.
Every tank has a specific lifespan and it certainly cannot meet your needs forever. However, for maximum use and longer life, it is better to install polyethylene tanks in hidden places so that they can work for you without problems for decades. Keeping bulk and ultra-bulky polyethylene tanks in areas where sunlight is in direct contact with them can cause them to become dry and brittle in the long term (tanks with anti-UV for 10-20 years). The point that owners of polyethylene tanks should pay attention to is to know when the polyethylene tank is reaching the end of its life and when they should replace it. If there is not enough care and maintenance in the use of polyethylene tanks, they will be destroyed sooner than usual, and any valuable liquid stored in them will also flow to the bottom of the tank and be lost.
The rotational molding process, which is also called rotation, is performed at low pressure and high temperature, and during this, the desired mold is rotated 360 degrees around two perpendicular axes to create a one-piece hollow object. come The mold in which plastic or polyethylene is poured to take the desired shape is made of steel and never changes its shape until the polyethylene tank is precisely shaped as desired. In the first stage of rotary molding, a form is filled with polyethylene powder. The amount of polymer that is poured into the mold depends on the size of the tank (bulky, ultra-bulky, 10,000 liters or 20,000 liters or more) and the thickness it needs (depending on its intended use and the liquids that will be stored in it). It depends. Next, the mold along with the powder inside it is transferred to the oven to be heated while rotating. The heat slowly melts the polymer inside the mold, and while the mold is slowly rotated around two different axes, the powder inside the mold is completely melted and controlled by a computer that controls the angle of rotation and speed, with which the size, shape and thickness can be determined. easily chosen, it takes a desired shape.
