Granulation and recycling of plastics recycled and made using extrusion equipment. In Russia, by extrusion processed more than thirty percent of the manufactured thermoplastic, including those such as PVC. The main equipment of the extrusion process of production of PVC edge, as noted above, is an extruder equipped with a shape of the head or die. Prior to submitting to the extruder in a special mixer by intensive mixing of PVC with all the additives for the formulation of the mixture. Equipped with all the required additives and need dried PVC can be fed to the extruder for the final processing.
It should be noted that the uniform dispensing of the material provides a better quality of the extrudate, and, consequently, higher quality of products made of PVC edge. In the extruder the polymer material is melted, plasticized and then injected into the die, ie, the extrusion process consists of sequential movements material in the areas of nutrition, plasticizing, metering of the melt, and then move through the form of a melt and cooling channels. A distinctive feature of today produced plastic PVC edges for facing CPD is the possibility of an accurate selection of colors and simulated wood grain or any other material such as metal (aluminum, stainless steel, bronze, etc.), ceramics, stone, etc. In the world's major producers of PVC edge (for example, REHAU or MKT) range exceeds 40 000 choices of colors, shades and patterns of embossing. PVC edge usually do not require special storage conditions: before using them enough to withstand climatic conditions of the production area. The use of PVC edge in the production of furniture elements gives increased wear resistance, durability and protects the ends of good products from chips, moisture and other damage possible during operation. Pieces of furniture, lined with PVC edge, the most widely used in the manufacture of cabinet household and office furniture (desks, cabinets, shelves, cabinets, etc.). The main furniture elements that use PVC edge are tops (written, computer, cooking, coffee tables, etc.), since they are most often exposed to external mechanical stress during operation.
