BC. In the year 2800, the Egyptians knew to stick thin wood strata, thicker logs, for decorative purposes. Over time, it is noticed that a wood panel obtained by overlaying thin layers is more durable than a solid wood panel of the same thickness.
However, this feature of the wood is neglected until the 19th century, were used as covering elements only for decorative purposes. In 1830, the Austrian carpenter Michael Thonet shaped very thin slices of wood in the form of steam. Then he glued them together and produced different kinds of furniture. Over time it has been proven that these furniture are much more durable than similar ones made from solid lumber.
Plywood is a forest product used intensively in the construction industry. Resistance to water and high strength are important for this sector. Especially used for preparing concrete molds. It is a very suitable material for uncoated mold systems, also known as gross molds.
Plywood is a panel of plywood. Although it has very good mechanical durability, it is a light material. The number of layers is usually produced as a single number. The outer layers are generally parallel to the long dimension of the panel. The successive layers are adhered so that they are perpendicular to each other. This form of production is a structure that resists the shock effects of vibrations that increase resistance.
Plywood, an increasingly used formwork material, now takes the place of traditional wooden molds to get gross concrete. As you know, Plywoods are divided into two types, filmed and non-filmed.
Contrary to what is known, the difference between them is not related to durability but only affects the concrete surface. It is straightforward to use film materials on surfaces not to be plastered, and it provides you with bright gross concrete. On the surfaces to be plastered, filmless plywoods must be used. The surface of the concrete taken in untouched materials is still not brilliant. This feature allows plastering.
Because of the lack of proper materials in the right place, you may encounter additional costs later. Due to the use of film materials in plastering, it will be necessary to put up with some chemicals again and a plus.
As a result;
Products originating from Finland, Russia, Romania, India, Indonesia, Malaysia, Chile, Brazil, USA and Canada can be used in places where film materials are used to create surfaces that are not plastered. It is imported to Turkey. There are no plywood productions in Turkey. Share Info Çoğalsın
