Making Plywood (Multiplex) and Briquette Wood

Initial process is basically the same as the process of making wood veneer because plywood is made from a layer a few sheets veneer. Artificial board manufacturing, in this case the multiplex, is a continuation of the manufacturing process veneer.
Choosing Log
The first step in the manufacture of artificial board is to select the log. Log chosen based on straightness and it diameter round or not. Well logs for plywood manufacture are free of knots.
Debarking to Veneer Drying
This process is exactly as described in veneer process.
Gluing
Application materials using roller coater systems and glue adhesive used are urea resins type or phenol-Formaldehyde. Type of glue that contains formaldehyde is less well known to health and the environment in which chemicals are used to make this glue can cause cancer. That is why some large consumers today require furniture manufacturers use artificial board that is free formaldehyde content in a way to test regularly. There are several standard measurement and methods of testing for these chemicals. Highest grade is E0, which means ZERO emissions. Then there are grade E1, E2 and so on.
Pressing
Veneer layers are arranged under the press machine with high pressure until the desired thickness. A plywood press machine can load 50 sheets plywood at once for single tap 3-4 minutes. There are different types of glue, can be done by 2 pressing different methods, hot press and cold press.
Hot Press: Commonly done to plywood with softwood raw materials with the temperature reaching 120 ° C for nearly 10 minutes. Accuracy presses time, high pressure and temperature is very important in this process.
Cold Press: Done with a hydraulic press or swivel. Type of glue is used usually a resin or urea-formaldehyde which has a longer drying process. Presses performed during 4-24 hours.
Cutting, Sanding
Plywood sheets that have been dried then cut to fit the standard length and width direction. Plywood surface smoothed with sanding machines and production defects cleaned or repaired.
Quality Control
There is a high grade of plywood, known as a quality standard A to C. A representing the highest quality and C is the lowest quality. Quality standards for plywood, among others: there is no overlap veneer or peeling, color and fiber of wood and plywood accuracy thickness.

Briquette Wood
At least 15% of the logs woods you buy become sawdust and shavings after the production process to finished goods. What is usually done by a furniture factory for this waste? For factory that waste output is not too much can still get a way out by way of selling to collectors and then the powder they use for various household purposes. Some people even need powder to help the process of burning bricks or tiles. On a visit to the wood factory last week, I saw a small production of wood briquettes. A few years before had ever seen a similar process but in a special place is the size of the room is used for making wood briquettes.
For what are wood briquettes? In winter, European countries and the United States use fireplace to heat the rooms in the house. They could use solid wood, both wood left over from processing wood or new felled forests but the more expensive and considering the policy of these countries about the environment, wood briquettes to be the best alternative and cheaper. Back to the furniture factories that make briquettes, this could be a good idea for most furniture factories in Indonesia to collect all the wood waste and process it into briquettes. Although the actual this waste can be used by manufacturers of artificial board or plywood. The difficulty that I have heard from furniture businessman is still limited manufacturer of making machine wood briquettes so that its price becomes expensive. One of the retailers for this product is Irishbiofuels. Briquettes or firewood has market potential is high enough considering the price of fuel today's high enough. Consumers in subtropical countries tend to reduce consumption of oil as heating fuel.
