Polymer hatches, the price of which is affordable, began to appear more and more often on the modern market, attracting the attention of manufacturers and users with their practical properties. The official name is polymer-sand composite, the material is actively used in various construction processes. It also solves the problem of plastic waste disposal, which is a relevant issue today. Sewer hatches are often made of polymer sand composite, which has a number of significant advantages. Let’s talk about them in more detail.
Features of composite production
Synthetic plastics (polymers) serve as raw materials for the production of composites.
Another component of the material is fine quartz. But it must be free from dust, additional particles and clay impurities. Only well-dried, purified sand is allowed for the production of composites. The mineral composition and origin do not matter.
The technology of production of polymer composites consists in grinding and mixing raw materials in a special unit. The resulting mass is a bit like dumpling dough. Its temperature can reach 190 ° C. The more sand, the harder the mass. Products are produced under pressure in special devices.
The material can be of any color, you just need to add the necessary dye to the mass. Since it is inside, evenly distributed throughout the mass, you can not worry that the products will begin to lose color over time.
It is important that the material is not afraid of mold and bacteria. It is resistant to temperature changes, aggressive environments, has hydrophobic properties and a long service life. Due to this, the polymer-sand composite is actively used in the production of construction products.
Manufacture of manholes for sewers
It is difficult to imagine modern sewers without manholes. All sewer openings are closed to protect against the ingress of garbage and theft of equipment. The ideal option is a manhole – a reliable and strong fastening. Previously, cast iron was used to manufacture manholes, but modern polymer material perfectly copes with all tasks, costs less, is not subject to theft. Since it is environmentally friendly, it can be used near pedestrian areas and landscape.
Advantages of polymer sewer hatches
In terms of strength and reliability, composite plastic hatches are in no way inferior to cast iron hatches and have several more serious advantages, namely:
In the modern market, you can find and buy plastic hatches of several types, which differ in varying degrees of strength. Some of them can be used on highways. There are models with installed metal plates, thanks to which they can be found with a metal detector under snow or ice.
With the development of technology and the invention of new materials, ordinary things began to change their properties, characteristics, and even appearance. They became more reliable, stronger, and more durable. A striking example of such changes is the appearance of polymer hatches, which successfully replaced their cast-iron counterparts.
Depending on the load level, the following types of polymer hatches are distinguished:
During production, composite materials are used, which allow to reduce the cost of the product, extend its service life and allow the consumer to choose the best option from a wide range. Polymer hatches are not destroyed by UV radiation, are not exposed to corrosion and withstand temperature changes. The main advantages are reliable fastening and low weight.
Disadvantages of polymer hatches
Polymer hatches also have their drawbacks. First of all, there are limitations to their use. They can “survive” a passenger car collision, but large cars can damage the hatch.
Where are polymer hatches used?
Polymer hatches are installed in parks, parking lots, factories. They are also suitable for sewer wells. This is a real find for owners of private houses and public utilities.
The material is a dielectric, so it can be used at gas stations. The field of application is constantly expanding, since the polymer-sand composite has recently appeared on the market, not all productions have had time to test the new product and evaluate its advantages.
Installation of polymer hatches for sewage
Another advantage of hatches made of polymer composite is simple and quick installation. By following simple rules of use, you can significantly extend the service life of products without damage. First of all, you need to choose the right hatch. The supporting ring is installed on the manhole cover. It is not recommended to immediately install the hatch on the manhole, this does not comply with safety regulations. The supporting ring increases the supporting area, the load on the plate is reduced several times.
Some craftsmen prefer brick. But it crumbles quickly, and the service life of the hatch decreases. Therefore, experts believe that the supporting ring is even better.
Another important point is to take care of the height of the hatch. It should be at the same level with the sidewalk or roadway.
It should be remembered that the plastic hatch is mounted only horizontally. In this case, the load will be distributed evenly during the collision. If this rule is violated, the product may crack or be damaged.
For the correct implementation of the product, when installing a polymer hatch, we recommend contacting specialists. They will select the type of composite product for the needs of the facility, carry out appropriate preparatory work and precise assembly.
