Plywood Essay Research Paper PlywoodPlywood is a

better, more modern equipment and synthetic glues that are of a much higher

quality than those produced 1500 years ago. So with our modern technology

we can make far larger sheets and the plastic based glues hold the plywood

together through almost any weather conditions. Some plastic bonded

plywood can be continuously submersed in water without coming apart.

Even stronger plywood is made using heat setting plastic glues. The veneers

are impregnated with the plastic based glues, pressed together and heated.

The veneers unite to for a material that is stronger per pound of weight than

steel. Curved surfaces sheets of plywood can be made in almost the same

way by impregnating the veneers with the glue and pressing them together in

a shaped mold and heating it up. The wings and fuselages of smaller aircraft

are often made in this way. The body panels of Woody Wagons were

made in this way too. When wings and fuselages of airplanes are made in

this way it is supposedly safer than metal because unlike metal the plywood

will not break when exposed to continuous vibrations and stress. It is also

lighter than metal. Many prefabricated buildings are made almost entirely out

of plywood. Plastic bonded woods are used for the exterior while ordinary

plywood is used for the floors and walls of the house. Sometimes the

cabinets counters and cupboards are all made of plywood too.

Another type of plywood is laminated wood . Laminated wood is

made by gluing two or more strips of wood together with their grains running

roughly in the same direction. A piece of laminated wood is no stronger than

a piece of wood that is the same size or kind, but its strength is distributed

more evenly and is less like to warp from fluctuating temperatures and high

humidity than regular lumber. Laminated wood is often used for either

curved or straight roof beams.

The plywood industry employs a great deal of people in the mill and

out in the bush as loggers, surveyors and forestry officials as well as truck

drivers. When all of the wood is gone off a lot the company that had the

timber license must ensure that the lot the timber was taken from is reforested

which also employs the people who replant the lot.

Although there are a lot of people who complain about the amount of

timber harvested, and rightly so, if this timber is replanted as harvested there

should never be a short supply of trees to make plywood out of. These

people have a right to complain if the forestry practices code is violated but if

the code is not violated they should not complain because their house most

likely contains wood or wood products. Some of their friends of family

members also probably have a job in the forestry industry. If the forestry

industry was shut down many people would be out of work and living on the

streets. Also houses and especially other larger buildings would become

much more expensive to build because instead of plywood and other wood

products houses and other building would need to be made of brick
