Plastic formwork is widely used in the construction industry, here we introduce the concrete polymer formwork, whose main body is made of compressed polymer, unlike other concrete formwork, so today, due to its many features, it replaces the concrete metal formwork. and the plywood is laminated, although the body and materials used in making the plastic formwork are made of polymer, but the polymer concrete formwork has different uses in the field of construction, the most common and widely used of which is the formwork of the column, roof, and wall, which will continue to We will describe them, but before defining the types of concrete formworks, it is necessary to get acquainted with the advantages of using plastic formworks.
In the current century, polymer formworks have been one of the most widely used types of concrete formworks in the construction industry, which are used for molding concrete and in general for the construction of all kinds of concrete structures. The main body and skeleton of these formworks are made of compressed polymer. Because this increases the strength of the formwork, although the body and materials used in making plastic formworks are polymer concrete, but the strength and durability of these formworks increases their quality.
There are different types of polymer formworks and they are one of the most common and popular types of formworks. Wall formworks, column formworks, and ceiling formworks can be mentioned among the uses of this product, which you will learn about the advantages of each of them.
Advantages of concrete plastic formwork:
1- One of the most important advantages of concrete plastic formwork is the light weight of this formwork because weight and lightness are one of the most important factors in building construction, because the lighter the weight, the lighter the structure and the easier its implementation, so this problem has caused This format will become more popular than ever before.
2- They can be used in cold regions with cold and dry weather and special climatic conditions because polymer formworks prevent the penetration and transfer of cold to concrete structures and prevent freezing of concrete, so in these areas more are being used.
3- Although the plastic formwork is a very suitable formwork for making concrete structures in cold regions, it is interesting to know that these formworks can also be used in tropical regions because they are common and since the surface and top of these formworks are like other formworks Metal is not made of metal, therefore it prevents the transfer of intense and high heat to the casting surfaces and prevents drying and evaporation of moisture and water in the surface layers of concrete.
4- Finally, after opening, there is no need to clean the formworks.
Before checking the price of plastic concrete formwork, it should be said that polymer formwork is a type of plastic formwork that has high strength while being light, the other name of these formworks is ABS, which has high impact resistance, so the pricing of this type of formwork is It depends on a wide range of factors such as the polymer used, the size of the formwork, the quality and color of the polymer, the accuracy of the plates, etc.
Basically, types of polymer formworks are offered in two styles, the first style includes rectangular and square columns whose width is different from the other, and the second style is also known as corner molding, which is usually available in small sizes and for Molding the narrow points of the building and increasing it is used, but another type of modular plastic formwork that is produced with fixed dimensions of 50×100 is known as 5-edge formwork, which is an alternative to waffle top, which is light in weight and in terms of resistance in conditions. They are located well, therefore, in general, the modular formwork is a good alternative to plywood because it does not have the problem of multiple layers of boards rotting, and it is cost-effective, and these formworks do not need to be lubricated.
One of the most important features of the plastic formwork is its lightness, so that there are no problems in moving and it has a high impact resistance, so this product is very suitable for the humid climate of the north and south of the country and does not need lubrication. And because of its smooth surface, there will be no need for a facade, so water is enough to clean the plastic formwork and there is no need to use any other cleaner, so you can use this formwork model more than a hundred times because of its abrasion resistance. It is very good and they are completely environmentally friendly and can be recycled.
Since the polymer concrete formwork has replaced plywood, it is becoming more popular day by day because the weight of such models is less compared to multi-layer panels, which makes it easier to implement and move better. Therefore, metal pins and nails are needed to attach these forms, but no special tools are needed to install them because the resistance of modular forms is high and there is no problem against wind, but multi-layer panels usually do not have high strength, so maybe The price of the plastic formwork may seem a bit high, but its high durability, easy installation and accurate implementation made this formwork replace plywood and many people agree with it.
In fact, the difference between black and white polymer is its flexibility, and white polymer is more flexible, but it is necessary to say that the opinion that black polymer formworks are secondary materials is completely wrong, but one should not be far from the fact that black formworks are secondary materials. They are offered to the market at a low price, in fact, the main characteristics of the polymer and its standards, such as the rarity of its imports or its domestic production, play a significant role in pricing, so the use of white materials in the production of plastic formworks increases the life of the formworks and their resistance. They are against hammer blows.
Due to the type of polymer it is made of, the black concrete formwork has a more reasonable price than the white concrete formwork, but it does not have the necessary resistance, but the main reason for the price difference is its rarity and the fact that the white polymer and its properties are similar to anti-ultraviolet rays. but white and black polymers both have quality ratings, and profit seekers may use second-rate materials in the production of this plastic formwork, which may cause a waste of capital and create structural implementation problems in addition to creating danger in the workshop.
In general, the dimensions of plastic panels are produced in 3 different sizes, by connecting these formworks, different sizes of concrete formworks can be created, which are mainly as follows:
In the discussion of the comparison of metal formwork and polymer formwork, it should be said that nowadays metal formwork has received much attention due to its reasonable price and responding to the needs of users, but if the metal formwork loses its quality and strength, it will cause problems in the implementation of the formwork. Therefore, processed concrete formworks are not suitable for use in exposed concrete, and to prevent it from sticking to concrete, a large amount of formwork oil or burnt oil must be used, but plastic concrete formworks can be used in exposed concrete at a lower price than metal formworks. It is used and does not stick to concrete in any way, and there is no need to lubricate the formwork.
