Plywood Production From Trees Plywood - A strong plank made from thin layers of wood glued together. People chop wood off trees followed by converting them into logs. Veneer is a thin sheet of wood peeled from certain logs and inserted into one machine that processes all the veneers. It is then sized and graded so that the best sheets are used in producing plywood panels. This is a vital step in the sorting process as it guarantees that plywood will be hard and endure longer.
When the veneer sheets are ready, they get sent to a plywood factory and its where all magic happens. The drying area is the first region for a machine. This machine will dry the veneer to a certain moisture content, not too wet and not too dry. Now this veneer after dry, pass it to the next machine which is arise as Glue spreader. This device applies a thin film of adhesive to each sheet or layer of veneer.
The sheets are piled so that one is on top of the other after which glue is applied. Each layer as they stack them but most importantly the direction of the wood grain needs to be changed. This unique cross-graining process is what makes plywood so strong and hard-wearing. These veneer sheets are pressed against each other in a machine called the hot press. Adhesive on both sides of the plies can bond together to form a rubberized unit when heat and pressure are applied with a hot press.
Plywood manufacturers are able to produce the sheets so cost effectively in part because they use smaller, lower-quality pieces of wood that would be unsuitable for building any other way. When the timber industry uses particular pieces to make plywood, it allows them to minimize wastage and more fully utilize every tree cut down. This allows them to be more sustainable and caring for planet while still delivering a valuable product.
The making of plywood is a detailed process and typical care has to be taken. Each sheet of veneer is individually inspected to identify the best possible match. Each sheet must receive just the right amount of glue so that it is not under nor over-coated. The last and needed work for the hot press is applying only enough heat to be able finally make plywood that will be really strong and durable.
Based on the applications, different types of plywood are made. In another case, marine plywood can withstand most types of water and moisture exposure - making it an ideal material for boats and other aquatic ventures. Exterior plywood, as its name implies, is made for outdoor use and best suited where it will be exposed to the elements such as rain and sun.
Plywood also has the advantage, in contrast to solid wood, that it is able to be strong and stable with less material. That means fewer trees have to be cut down, using the same amount of construction materials. The use of plywood allows us to conserve trees and still maintain the durability needed for building and other applications.
