polymer sheets; Functional materials with multiple uses
It is very common to use polymer materials in various industries due to their properties and many applications. These materials are used in making all kinds of polymer sheets, polymer concrete, use in polar solvents, food industry, alkaline and acid environments, tank linings, packing steel coils, etc. With high resistance to chemical factors and affordable cost, polymer sheets are used as a group of the most widely used materials in various industries. Based on this, in this article from the Tehran Plimer Sharq website, we are going to do a complete review of polymer sheets.
What is polymer sheet?
Polymer sheet is a kind of durable and functional coating with extremely low permeability, which is used to pass all kinds of fluids. This type of sheet consists of a large number of interconnected sheets, which after being impregnated with materials such as: Elastomer, geotextile and polymer sprays are made into polymer sheets. Also, in the production of raw materials for polymer sheets, the raw materials include: There are polyester resin, plasticizers, carbon black, antioxidants, lubricants, and carbon black. In polymer engineering, extrusion and calendering processes are used to process these sheets.
Advantages of using polymer sheets in industries
All kinds of polymer sheets are resistant insulation for storing and conducting fluids, which, due to their chemical compounds, have a high resistance to tearing, decomposition, and ultraviolet (UV) rays. Also, having a low coefficient of thermal expansion, high flexibility and resistance to perforation, the use of these sheets in environments close to water or acidic environments has become common. Of course, do not forget that the applications of polymers are not only limited to the production of sheets; They can also be used to produce materials such as air-dried polymer paste.
Accordingly, the most important advantages of polymer sheets are:
- Resistant chemical coating to prevent surface corrosion in corrosive fluid ponds and tanks
- Possessing antistatic properties and preventing sparks and trapping electricity
- The possibility of ordering sheets according to needs in different thicknesses and sizes
- Preventing rapid ignition due to the property of fire block
- Transparent, semi-transparent and non-transparent production based on customer needs
- Having suitable thermal resistance and high pressure tolerance against water
- Using all kinds of sheets with different thickness and good quality
- The neutrality of the sheets against additives and pollution
- High resistance to being chewed by animals
- High resistance in dry and wet environments
- Ease of making large sheets
- Excellent resistance to cracking
- Having a useful life of 40 years
- Free of any toxins and harmful substances
- Resistance to earthquake waves
- Very high permeability
- Eco-friendly
- Simple replacement and repair
The process of making and processing polymer sheets
Polymer sheets go through a complex and specialized manufacturing process to reach the production stage. These sheets are put together using polyethylene welding or using other specialized methods, and in their structure, polymers such as: Polyvinyl chloride and polyethylene are used.
In general, for the production of polyethylene polymer sheets, HDPE polyethylene is used, which should be easily cut. Also, due to the thermo-softness of these sheets, the polymerization process must also be carried out in their production.
In the process of making and processing polymer sheets, first, criteria such as: Melt flow index, molecular weight, crystallinity and density are evaluated. Then the extrusion process is used to produce sheets. In this process, the white or colored granule goes through the melting and extrusion process, and after changing its shape, it becomes a sheet and is cut in thicknesses of 3 mm (poly 3) to 200 mm.
On the other hand, after melting in the tank of the sheet-making machine, the petrochemical granule turns into a liquid and maintains its liquid state by being exposed to high pressure and temperature. When the degree of fluidity reaches the desired level, this material is removed from the ejector of the device (head) and the product is produced, and after the product is in the form of warm paste sheets, the thickness and width of the sheet are applied according to the customer’s order.
polymer sheet; A resistant material with various applications
Due to its unique features and various advantages, the use of polymer sheets is increasing day by day. For this reason, many industries such as: Road construction and agriculture, automotive, plastic and paper material manufacturers, construction projects, etc. can benefit from the benefits of purchasing polymer sheets for various applications.
Some of the most important applications of polymer sheets are:
- Making a workbench
- Manufacture of pharmaceutical and laboratory equipment
- Design and implementation of flooring and ceiling
- window protector
- Sealing and covering the building
- Packaging Industry
- Construction of irrigation equipment
- manufacturing car parts
- Leaching ponds
In general, the installation of polymer sheets is very quick and easy and does not require expertise. Also, according to the quality of the sheets and the thickness of the production, these types of sheets are more affordable than the expensive stone and concrete coverings. Accordingly, in the following, we will discuss the most important applications of various types of polymer sheets.
Construction of agricultural ponds
One of the most common applications of polymer sheets is the construction of agricultural pools. According to the properties of polymer pool sheets, these sheets are usually used in earthen pools, which have more applications than concrete pools. The important advantage of using this material for the production of agricultural pools is the lower price of polymer pool sheets compared to concrete structures. Heavy polymer or HDPE sheets are used in the construction and implementation of this type of industrial pools.
Accordingly, the most important advantages of using polymer sheets in agricultural pools are:
- Very long life
- Sufficient resistance to sunlight and temperature rise and fall
- Having suitable resistance to concrete
- Having thermal resistance between +80 and -70 degrees Celsius
- 100% impermeability against materials compared to concrete and stone materials
The role of polymer sheets in the implementation of aquaculture ponds
Another type of polymer sheets used in the construction of industrial pools are geomembrane polymer sheets, which are used for the construction of aquariums. Due to their complete impermeability, these sheets are used as thermal insulation in the construction of aquatic pools.
Due to the neutrality of the polymer sheet and its non-combination with other materials, many entrepreneurs of the agricultural industry use this material to build all kinds of fish and shrimp breeding ponds. In the composition of polymer sheets, there are biological materials and polyethylene, which are the best option for the implementation and installation of the aquarium breeding pond due to the lack of adhesion with other materials.
Isolation of roof gardens
In addition to industrial applications, it is also very common to use geomembrane polymer sheets to insulate roof gardens. Polymer insulation, along with the basic drainage system, gives you the possibility of using an excellent insulation material with light weight, longevity and very high resistance.
Insulation of tunnels with the help of polymer sheets
Many industrial projects use geomembrane polymer sheets to isolate structures such as tunnels. This material is a suitable alternative to concrete due to its high flexibility in corners and inaccessible points and faster installation. Among the types of polymer sheets, heavy sheets or HDPE are the best options for tunnel insulation. Also, the use of VLDPE sheets is very important for insulating and sealing tunnels and preventing water infiltration and destruction of the structure.
