The technology of manufacturing plastic containers
Thanks to the technology for the production of polymer containers, they can store technical, drinking water for a long time. Therefore, they are in demand both in summer cottages and for housekeeping in a private house.
Water tanks are made using seamless technology. The material for the manufacture is plastic in sheets, which, according to international quality criteria, is environmentally friendly, safe and durable. It is convenient when creating products, as it is easy to cut and weld.
For the manufacture of tanks, plastic sheets are heated, given the desired shape and fastened by seamless welding using welded rods.
The heated material is plastic, easy to mold. Therefore, at this stage, the installation of additional parts.
Depending on the purpose of the storage tank, it can be equipped with:
- locking ceilings;
- handles for transportation;
- heating element;
After giving the product the necessary shape, the finished tank should cool. After solidification, it is ground at the junction of the sheets and the installation of additional elements.
Polypropylene containers must be purchased in accordance with their intended purpose, therefore, before choosing a container for a summer cottage or for agricultural purposes, it is necessary to determine the complete set.
At the request of the customer, the tank can be equipped with additional accessories:
- float, to visualize the liquid level;
- galvanized metal frame for extra strength;
- case and pallet, for outdoor use;
- lid with air valve to preserve the properties and freshness of drinking water.
Fair manufacturers use certified equipment and materials. The consumer, in this case, receives the product without additional seams, from a material of a homogeneous fraction. Such a product will be durable, environmentally friendly and reliable in operation.
Violation of technology in the production process reduces the service life of plastic tanks. Some products are initially unsuitable for use. To avoid such troubles, the company must issue a certificate of quality for the goods.
Pros and Cons of Plastic Tanks
The advantages of plastic tanks are related to the material from which they are made.
Therefore, the main advantages of polyethylene containers for water are:
- Low cost. Due to the unstable situation in the financial market, the price of raw materials is increasing. Prices for finished products have the same trend, but in comparison with tanks made of other materials, the cost of plastic products is much lower.
- Light weight. Transportation, loading containers made of polypropylene can minimize energy consumption. Plastic barrels for transporting liquids, mounted on the frame or in the car body, reduce the load, facilitate the installation and dismantling of the transportation system.
- Plastic is resistant to decay, corrosion, detergents. In this regard, the product retains an attractive appearance for a long time.
- Material structure It repels UV rays, so the properties of water stored in a plastic container for a long time will not change, even if the tank was not in the shade on the street.
- Temperature Rangein which the product can be operated without loss of properties - from -40 to + 50 ° C.
- Term of use storage tanks for water from polypropylene, depending on operating conditions, location, and ranges from 25 to 50 years.
Plastic tanks can be installed in the house and on the street. Moreover, on the street, containers can be placed on the podium, on the ground or buried in the ground.
Underground placement reveals the first drawback: frozen groundwater can push the light structure out. Optimal grounding and a retaining structure are required to maintain the water storage.
If the outdoor temperature has long been close to the lower limit, you should move the tank to a heated room. For the winter period, it is necessary to completely drain the water, since its possible expansion will lead to deformation of the walls of the bowl.
If you use water from a polyethylene tank that is not intended for food purposes, you can be harmful to your health, since the interaction of technical plastic grade 03-07 with water, and when heated, releases hazardous substances - bisphenol and formaldehyde.
With proper operation, these shortcomings will not affect the quality of the water in the tanks.
Varieties of Plastic Tanks
Storage tanks for water from polymers vary in shape, volume, color, material and purpose. Choosing a suitable tank, it is necessary to analyze what characteristics of the product will be optimal for meeting household needs.
Material for manufacturing
For the manufacture of containers used light polymers: polyethylene and polypropylene. Polyethylene products are used in everyday life for storing drinking and industrial water.
Polypropylene tanks Suitable for use in industrial plants and factories. Dense, stable containers for technical and chemical liquids are smelted from polypropylene sheets.
Plastic barrels for drinking water are made from pure food grade polyethylene. Such material ensures the preservation of the chemical composition of water, prevents the multiplication of putrefactive microbes and bacteria.
There is a technology when the base material is coated with a special antiseptic coating on the inside of the tank. The inner, white layer protects the liquid from flowering and bacteria, and the outer, blue layer creates a barrier to the penetration of sunlight.
Abrasive cleaners must not be used to treat double-layer drinking water storage devices so as not to damage the integrity of the thin coating.
Color difference in containers
Polyethylene containers are available in four color options: white, blue, green and black.
Blue tanks universal and used for storing food and industrial water on the street and indoors. Since a dense layer of dark blue plastic does not transmit UV rays, water, even during prolonged storage, does not lose its chemical properties and does not bloom.
Polyethylene green container, similar in properties to products in blue and dark blue. The choice of a green or blue tank is based on the personal preferences of the buyer.
White cans should be stored indoors without natural light, since light plastic does not protect the liquid from possible reactions. The white walls of the tanks have an advantage over the colored ones only in that you can control the amount of liquid in the tank.
Black containers designed for watering or for arranging a summer shower. Such products do not allow UV rays, they are very warm in the sun. Therefore, underground tap water quickly heats up and becomes suitable for bathing and watering garden crops.
Volume and shape of the drive
Storage tanks have different capacities. The smallest hold 20 liters of water, the largest - 10 tons.
For the transport of drinking water to the country, it is advisable to purchase containers of 20-50 liters. For arrangement summer soul tanks of 100-200 liters are in demand.
If tap water is unstable, then for irrigation and domestic needs a container with a capacity of 1000-2000 liters is suitable.
Tanks for 3, 5 and 10 cubic meters of water are used for industrial purposes and for transporting liquid, bulk cargo in special vehicles.
Polypropylene water tanks have a different shape. Therefore, both the owner of the cottage and the summer resident will select the best option for the bowl, based on the capabilities and purpose.
Cylindrical tanks occupy a minimum of space, therefore they are operated in bathhouses and houses.
Rectangular universal containers for storing liquids can be located underground and on the surface. A vertically standing rectangular tank saves space.
Cubic tanks They have a large volume and a wide throat opening convenient for filling. When installing the lower crane and installing the barrel on the podium, a complete drain of water is possible.
Flat elliptical or elongated conical tanks are installed on the roof of the summer shower. The shape, when the lower part is wider than the upper, allows you to increase the pressure of the liquid. For ease of filling, such containers are equipped with a wide neck opening.
This variety will allow you to install containers for water in any free corner without losing usable space, even if the cottage or plot has a small area.
The use of plastic tanks in the country
Living in a private country house or in the summer at the dacha, the owners of the plots have to adapt to the field conditions. A serious problem for summer residents is water supply organization plot.
The low price determines the demand for plastic tanks. Such containers are used to collect rainwater, irrigate the lawn and irrigate agricultural plants, arrange seasonal showers and drink.
In addition, individual tank models are used for the device. autonomous sewer. For people permanently living outside the city, in the absence of a sewage disposal channel, the installation of this engineering system is necessary.
Tips for choosing a polyethylene drive
For the manufacture of tanks, durable synthetic material is used - plastic, which determines the long-term operation of the products.
If its quality and manufacturing technology of products does not meet existing standards, then the capacity will serve half the guaranteed period or, with little physical impact, will immediately become worthless.
Therefore, when buying a plastic tank, you must consider the tips that will help you to get a really high-quality product.
Tip # 1 - Certificate of Conformity
When buying a storage tank for water, it is important to obtain a quality certificate for the products. Since the information in the document indicates that the product is made of certified raw materials, in good condition.
Obtaining a certificate of compliance is important when purchasing a drinking water tank. If the bowl was made of plastic grades 03-07, under certain conditions it emits life-threatening substances. Therefore, before paying, you must make sure that the container was cast from the primary food grade polymer 01 and 02.
If this document is available to the consumer, it is easier to return the product to the seller if there are claims to quality.
Tip number 2 - appearance
When you inspect the water tank, you need to make sure that there are no uneven walls. For this, special attention should be paid to the convex parts of the container, and if in any section the plastic has a lighter shade or bends at the touch of a finger, then it is better to refuse to buy this product.
In addition, it is important to ensure the quality of the seams, or rather, in their absence. High-quality joints are almost invisible, as they are performed by the method of seamless welding. The certified product excludes additional seams.
The attachment points of additional elements: bends, flanges, drain, handles, etc., must be carefully sanded.
Tip number 3 - easy transportation
If it is planned to transport water to a summer cottage, then plastic tanks equipped with special grooves should be considered.
By means of one or more notches in the base, the container is strapped and secured in the trunk, in the car body.
