There are several common types of   plywood : Sanded plywood features face and back (top and bottom) plies that are sanded in the manufacturing process. It is used in places where it is visible, such as for cabinets, shelves and paneling.  Hardwood plywood is made from hardwoods like birch, maple and oak. The plies are glued at right angles to one another, making the plywood very strong and stable. It can be heavier than other types of plywood. Use hardwood plywood for furniture and anything that requires a strong load-bearing frame. Plywood sheathing or structural plywood is designed for permanent structures. It is strong and inexpensive, but unfinished, and therefore not suitable for places where it will show. It should be covered by other types of materials. Use plywood sheathing for framing, beams, flooring and bracing panels. Project plywood panels are ready-to-use, pre-cut plywood boards designed for quick and easy DIY projects. There are various types of wood, ply and p...

  Generally speaking, ordinary   building formwork   can be used 5-8 times, and innovative formwork products can be used 10-15 times, the repetition rate is very high.  There are some factors that affect the reuse rate of building formwork. They are quality of building formwork and use and maintenance of building formwork. When using building formwork, pay attention to standard installation to avoid external impact or serious wear on the formwork. Cleaning up and store it in a place where  flat, dry and ventilated after disassemble the formwork. When storing building formwork, it is necessary to avoid sun and rain and don't put with corrosive substances, which can increase the repeated times. As a professinal manufactur,  ZMADTO  advise you that the building formwork that reaches the quality limit, we should replace it in time since it is about project quality and construction safety.

There are macrocapillary and microcapillary systems in the wood tissue of the   building formwork . The water in the macrocapillary system is called free water, and the water in the microcapillary system is called sorbed water. In addition, a small amount is combined with wood molecules in a combined state of compound water.   The resistance of water movement of high-rise special building formwork, in the drying of veneer, the direction of water movement is mainly transverse conduction perpendicular to the direction of fiber arrangement, so the largest resistance is the resistance of pits, followed by the resistance of cell cavity and cell wall. The greater resistance that affects the evaporation of water, and the critical layer where the surface of the veneer is in contact with the air. When the thin layer in contact with the surface of the high-speed plate, the speed is close to zero, and it is a stagnant air film that separates the air from the surface. This film is called ...
