As we know, the wood industry plays a major role in interior decoration and architecture. A wooden chair has traveled a long way to reach our homes.
Here I am writing a series of brief articles about wood that I hope other friends will benefit from their experiences.
Wood veneers:
1- Artificial (Letron): Melamine, Formica, HPL
2- Natural: plywood, particle board (chipboard), fiber board (MDF, HDF). Cement wood, gypsum wood.
Melamine sheet (Latron): it is a synthetic coating. It is used in furniture making.
The adhesive used is melamine formaldehyde, which is waterproof, anti-scratch and partially fireproof.
Natural veneer (chipboard): We turn the wood into a veneer whose thickness is less than 1 mm, and to produce it, it undergoes a process including the following.
1-raw material 2-peeling 3-shredding 3-drying 4-grading 5-sticking 6-pressing 7-cooling 8-cutting to standard dimensions 9-sanding 10-grading-categorizing
The raw material is actually the trunk of the tree, which has already been cooked in several stages.
MDF: It is important to select the sapwood (tree trunk) in fiber board.
In MDF (Medium Density Fiberboard), we have wood fibers, unlike chipboard, which had wood chips. One of the characteristics of MDFs is homogeneous texture and uniform surface. High mechanical resistance and good cutting ability, as well as high resistance to water.
HDFs are the boards that are used for parquet flooring, and it is the same MDF that has been subjected to more pressure during the pressing stage.
Recognition of wood
inside the wood
out of wood
The interior of the wood is more resistant to destructive factors such as fungi and...
All woods have inner wood and outer wood, some have different color and some don't.
wood cutting
1-Transverse: It makes us see the cross section of the wood
2- Tangential: It is a cut that is tangent to the annual circles, which gives us a very beautiful pattern in decoration.
3-Radial: It is in the form of smooth streaks and perpendicular to the annual circles

Plane tree:
The entire street of Beli Asr in Tehran is made of sycamore. It has a dense texture. It is semi-heavy and very useful in European furniture making.
Sparrow's language:
A semi-heavy and semi-hard wood with high elasticity, good coloring, bright yellow outer wood and bright brown inner wood.
Application: making airplanes, airplane propellers, skis, tennis and ping pong rackets. Wagon making and...
Walnut:
Semi-heavy. Semi-hard. High impact resistance and strong inside the wood
Application: steel furniture, coating, parquet, sculpture, carving, woodworking, very beautiful.
Pine:
It is very soft and it is very bad in beehive making, dry sauna, cheap furniture, construction wood, concrete mold and as stairs and parquet.
Elm:
Semi-hard to hard. The best coating in Iran.
Application: furniture and parquet making, ship building, wagon making, etc.
Spruce:
Very soft and white wood has no resistance against termites.
Application: match making, coating, ladder making, box making, paper making, cooler bag, scaffolding, candle making
Maple:
Semi-hard and without specific wood interior
Application: furniture, comfortable chair, dining table, curtain rod, musical instrument, nardo board...
yew wood:
It is one of the most beautiful woods in the world and stays healthy for years in the environment.
Application: Carving, cigarette wood, sculpting, etc.
