PVC baguette production technology 
Automatic translate
PVC baguette is an excellent material for framing photographs, paintings, caricatures or drawings. It is distinguished by its lightness, durability, and functionality, so every year there are more and more adherents of this type of frame. Wooden baguettes are going out of fashion, and PVC frames are becoming in demand and popular. Here you can see what beautiful, modern and varied types of this material exist now.
History of the baguette
Polyvinyl chloride began its existence in the 19th century. Back in 35 of the 19th century, the famous chemist Regnald synthesized PVC, and already in 72 of the same century, the German Bauman, using various chemical experiments, obtained this material in powder form. Many decades have passed during which attempts have been made to develop industrial production technologies. But only in 1912, the German scientist F. Klatte filed a patent for the manufacture of PVC.
During the period between the wars, experiments were carried out by large German companies on polyvinyl chloride. But other powerful countries, such as France, SAS and England, also did not miss the opportunity.
The then-famous BASF company made a breakthrough revolution in the world economy, and to this day this type of material ranks honorably second in the plastic market in terms of demand and prevalence throughout the Planet. After the Second World War, our state began production of this type of baguette, while borrowing technology from German manufacturers.
Production technology
The raw materials needed to make a baguette are approximately half chlorine and half ethylene. Chlorine is extracted from rock salt, and ethylene is extracted from natural gas. The result is a granular or powder product, it is used for the manufacture of various items, this can be polystyrene foam or metal-plastic windows. After which various modifiers and dyes are added to give the material the desired properties.
Then the use of the machine equipment begins, where the line for the production of PVC material for frames operates. An extruder consists of various machines. On average, the parameters of this line are as follows: the technological chain has a length of up to 35 m, a width of up to 3 meters. This is where the heating, foaming and extrusion of the material occurs, which at the beginning of the extruder looks like a shapeless sausage, but after this path becomes a beautiful PVC baguette.
When the material has acquired a curly shape, but does not yet have color, it is sent to the cooling stage, which occurs with the help of running water. An extrusion production line looks like rollers of various shapes that have different purposes. Here the baguette is given relief by applying a laminating film to imitate wood, marble or leather.
At the end of the work, the baguette is gilded or silvered, if of course there is a need for this. Then the finished material is cut by an automatic circular saw and then the products are packaged. This type of production is the most common, because modern technologies for making PVC baguettes are practically the same. The quality of such frames depends directly on the use of material, that is, each manufacturer changes the composition.
For example, large Chinese factories use high-quality polyvinyl chloride because they do not want to risk their reputation. And to reduce costs, small firms use recycled materials and convince buyers that this has a better effect on the framing frame.
Properties of PVC baguettes
Baguettes made from polyvinyl chloride have many advantages over aluminum, wood and other types of this material. They are valued for their strength, flexibility and excellent tolerance to temperature changes, which is why they are often used to make frames for wall designs. They serve their owners for a long time and do not cause any trouble. Plus, scientists have proven that this type of baguette is environmentally friendly and does not emit various toxins, which is very important for human health. Also, such frames do not fade in the sun and retain their color for a long time.
