The performance of the machine
Cooked packages are loaded into a hydraulic press using a lifting hydraulic table at the rate of 10 packages per floor.
After full loading the press, packages are closed and heated.
When heated, the polyhlorvinyl film and perchlorvinyl resin contained on the surface of the microshpon are softened and melted. In this case, gluing a microshpone with a polyhlorvinyl film occurs.
The front side of the film under pressure in the press is aligned and acquires a smooth mirror surface corresponding to the smoothness of the surface of polished gaskets. The company “Antonio Merloni” offers options for autonomous gasification of a private house. On our site
Pressing is carried out in the following mode: specific pressure 10-12 kg/cm2, plates temperature 130-140 °, withstanding time in hot press 25-30 minutes. Plywood is cooled up to 20-25 ° in the press (without pressure removal) within 15-20 minutes.
After cooling the press slabs, pressure is removed, the opening of the plates, unloading and disassembling the bags. Framed gaskets and pillows are served to the table and used in subsequent sets of packages, and the plywood is cut along the edges on the machine and laid in the feet, so that the front side of one sheet adjacent to the front side of the other. This method of laying plywood prevents damage to the front surface during transportation.
Consumption of raw materials, auxiliary materials, energy, water, workforce per 1000 m2 and the cost of plywood at a release of 500 thousand. M2 per year are given in the table.
Plywood faces the bases of furniture products from carpentry and three-layer wood-bearing plates. Products with bases from single-layer wood-based plates must first be tanned with a beam veneer.
Before facing the plywood, the surface of the base of the products is aligned, cracks, excitements, nests of the fallen knots and other defects with a pasty putty are sealed, then dried, put and sweat with a specific pressure of 8-10 kg/cm2 is carried out.
