What is Composites Bamboo?

Composites Bamboo  are processed bamboo. Bamboo split vertically into 2 parts. Then pressurized hot 25kgf per cm2 and 150 degrees centigrade for 30 minutes. Then laminated to the wood beams. Bow building consultant of the Dutch RDA Technologie BV, composites Bamboo proved that it had the strength and durability of wood equivalent to class I and II, as hard as merbau, bengkirai, teak.

Nor intang Setyo H of the Faculty of Engineering Unsoed said bamboo fibers have high tensile strength, 2 times the tensile strength of steel reinforcement. "When the bamboo used as a composite beam can save the use of wood and the cost was cheap," said intang. Bamboo durable because the silica content in the parenchymal tissue to achieve 0.1 to 1.78%.

Bamboo diameter homogeneous effect on the density of the composite. If using bamboo are smaller at the end, "The thickness can be made uniform with the provision of glue as a filler, but the density will be different," said Subiyakto.Bamboo is used at least 4 years old who have optimum strength. Compare with the age of the average tree decades.

In principle all types of bamboo can be made of composites. However, the best results obtained when using homogeneous diameter bamboo from the base to the tip such as bamboo Dendrocalamus giganteus Sembilang aka bamboo and bamboo rope Gigantochloa apus apus. .

Origins The idea of Composites Bamboos

According to Dr. Ir Subiyakto MSc – bamboo researcher at LIPI Biomaterials Research Center – the idea of making composites Bamboo begins visit to China. In a country that he saw the Bamboo Curtain bamboo floor coatings used to replace the terrazzo and ceramic tiles.

That experience continues imagined in his mind. After arriving in the homeland, researchers are interested in trying it. However, "There has been no crusher machines (graders, red) corresponding to the bamboo," said Subiyakto.

Incidentally father of 3 children saw wood shredder at Kyoto University, Japan. He imitated the design. The first engine is complete late 1997. It is driven electric motor-powered 7 horsepower.

The disadvantage, groove grinding wheel was too loose so pelupuh – which leveled parts of bamboo – which produced less smooth. As a result the process of alignment must be repeated up to 7 times. Therefore he makes a more perfect machine in 2000. The third groove inside the wheel presses different density, tenuous at the beginning, rather tight in the middle, and most meetings at the end. The difference plot is to refine and expand on cracks.

More and fine cracks, the better the glue uniformly dispersed so that the composite density and strength. "If the direct use grinding wheels that meeting, need more powerful machines. Also at risk destroying the bamboo, "said Subiyakto. With the new machine was quite a process 3-4 times. To produce a piece of composites Bamboo board measuring 240 cm x 120 cm x 4 cm, need 5-7 bamboo stems along the 6-7 m

How we create Quality Design of Indoor wood Furniture?

First,  we  aware that wood is hydroscopic material. So wood is easy shrink and expand because air moisture. Wood furniture is easy to crack and splitting.  To solve this problem, we always use dry wood ( 9% when fresh from the kiln dry), so degree of shrink is not enough to make furniture crack.

Second, Wood Quality is important for strength and durable furniture.  Usually, people differentiate wood by  species and by producer (perhutani and village), and by diameter. By experience, we know quality  not only by species, producer, and diameter, but also city where wood is grow. We maintain relationship with wood supplier to get more access  good quality of wood.

Third, to prevent termites, we  treat wood with termite  pest control chemical.

Fourth, Joinery and glue also is important to create strength construction of furniture. Chairs or tables often are loaded by human body, belting and etc. So it is important to make strong furniture to receive their usual treatment without destroyed or decay.  Standard wood dowel is good to join part of furniture.

Create cheap Indoor wood furniture wholesale without reduce Quality?

First, to create reliable good quality at low price, we always improve our organization to reduce waste of time, material and defect.  We also improve mode of production, kiln dry technique to create good quality.  We have several techniques to dry wood.

Teak Wood, Popular wood for indoor furniture

Teak wood (latin: tectona grandis) is also called jate, jatih, jatos, kiati, or kulidawa. The color of teak wood is light brown, brown-gray to dark red brown or red brown. Wood texture of wood is rather coarse and uneven. Fiber direction straight or sometimes slightly cohesive and smooth wooden surface or a bit slippery, sometimes like greasy (Martawijaya, et al, 1989). This oil also functions as a natural finishing. When compared with mahogany, red mahogany better, smoother texture, more straight-fiber direction, when compared with teak wood.
Teak wood itself is actually a variety of quality. Broadly speaking, there are two types of teak, the Perhutani and village. Perhutani Teak is teak which is managed by the Indonesian government, namely state-owned Perhutani. While teak is teak maintained village community. Perhutani teak wood grown in forests, the soil is usually dry, slow growth. So the wood fiber smooth and strong. While the large fibrous village teak and teak less robust than perhutani. But when compared to other wood, like mahogany, and much more MDF or Multiplex, teak wood village stronger still.

Alternative Wood of Indoor Furniture

Popularity Teak can close our knowledge of the potential of other wood. This will also make teak wood becomes more expensive, but there are also other wood that need to be taken into account. Martawijaya mention there are 10 other wood – between 4000 species of wood-the potential to become furniture.

• Mahogany is also known as mahony. Mahogany Wood belongs to Indonesia’s second favorite wood. In the United Kingdom, mahogany wood is special wood, more special than teak. Wood of this type has a characteristic color of reddish brown, red gradually become older. Texture rather fine wood and the direction of fiber blends, sometimes bumpy, and somewhat slippery surface. For natural finishing, Mahogany is suit,.
• Wood agatis (agathis celebica), also known as wood resin. The color of this wood is whitish to yellow brown, sometimes pink artificial. The wood texture quite smooth and flat. Wood surface smooth and straight fiber direction. The direction of the straight or sometimes twisted fiber and wood surfaces slippery. Agatis easily sawed wood and done. Agatis wood usually can be used for materials of the guitar, making it very flexible and can be used as raw material for furniture, including furniture minimalist.

• Equilibrium Moisture Content (EMC) 9-12 %. Why EMC of wood is important? All of wood is hidroscopic. Easy for moisture to enter and exit in the wood. Whe moisture enter, wood is expand. When moisture exit from wood, wood volume is shrink. If wood is dry before be manufactured, we can prevent furniture crack.
