The most famous material used in the process of making windows can be considered polyvinyl chloride or PVC. It is used in the manufacture of a variety of profiles of which then plastic windows in Minsk are then made in Minsk.
Polyvinyl chloride is an artificial material resistant to extreme temperatures invented at the beginning of the nineteenth century.
It is made from such natural raw materials as oil and ordinary salt.
Polyvinyl chloride began to be widely used in the manufacture of windows around the middle of the previous century, and thanks to their properties and constantly high demand among consumers, it is actively used today.
The final product – PVC profiles [1] are made using the extrusion method. Polyvinyl chloride, along with other ingredients (softeners, plasticizers, stabilizers, as well as fillers), is heated to a state of homogeneous thick substance. Then the resulting mixture is passed through a certain form and only then, gradually cooled. Ultimately, a hollow window profile arises with built -in air chambers, which are internal jumpers. .
On the one hand, this procedure does not seem too difficult, but at the same time one specific question arises: why the cost of various window PVC profiles sometimes differs quite sharply. The answer is that the price of the final product is not least affected by certain additives that are part of a specific mixture. In total, about a dozen expensive additives can be distinguished. An ordinary buyer will not be able to determine the presence of a particular component by eye, so some manufacturers can sometimes cheat, unfairly filling the price.
For example, if the mixture is not a very qualitative titanium oxide (the full cleaning of which is a relatively cost process), which directly responsible for the white color of the window, then after some time your windows will most likely turn on. In addition, you can distinguish special chemical components that can increase the impact resistance of the material. The extremely important process responsible for improving the quality of the profile can be considered the maximum uniform distribution of the used components in the mixture, as well as the correct cooler of cooling the manufactured product.
