Abstract

The invention relates to chipboard panels made from seeds of the casuarinas equisetifolia family, including filao. The seeds after harvest are transformed into powder or grain size fiber which is mixed with the liquid obtained by dissolving gum arabic in lukewarm water (50°-60°) The result of the mixture is a mattress for chipboard whose the shape and density depend on the intended uses (hard fire-resistant or insulating panels).

Abbreviated:

The invention relates to chipboard panels made from seeds of the casuarinas equisetifolia family, including filao.

The seeds after harvest are transformed into powder or grain size fiber which is mixed with the liquid obtained by dissolving gum arabic in warm water (50°-60°)

The result of the mixture is a mattress for chipboard whose shape and density depend on the intended uses (hard fire-resistant or insulating panels).

I TITLE: chipboard panels for thermal and sound insulation made from casuarina seeds (casuarina equisetifolia) and gum arabic extracted from acacia for thermal and sound insulation and floating parquet

The present invention relates to chipboard panels made from casuarina seeds (casuarina equisetifolia) and gum arabic extracted from acacia.

We know so far that the different kinds of agglomerates are panels made up of scrap wood shavings, residues from the wood industries or pieces of wood, residues from the wood industries or pieces of wood are glued with urea-formaldehyde (UF) resins during high temperature pressing.

The casuarina tree is native to Asia, but present in tropical regions.

The fruits are globular cones or lodge tiny seeds which, when extracted and crushed, can be agglomerated by a natural resin such as gum arabic.

II Problems that the invention seeks to solve

The chipboard panels known so far have the following problems:

° Crumbling in contact with water ° High wear ° Low impact resistance ° Need to use synthetic resins with consequent harmful effects on health during the manufacture of wood panels ° Damage caused to the environment by the 'felling of trees.

The examination of the sources of scientific and technical information, did not make it possible to identify inventions or innovations which use the particles of the seeds of filaos and gum arabic for the manufacture of chipboard panels contrary to the object of the present invention.

IY_Des_çrj.p.tjo.n A) Manner of carrying out the invention

The production of chipboard made from particles of casuarina seeds and gum arabic resin includes 5 (five) main phases, namely:

1- Preparation of the raw material:

The basic raw material for chipboard is the seeds contained in the fruits of the casuarina tree (casuarina equisetifolia).

The preparation of the seed bed consists of harvesting the casuarina fruits and crushing them to obtain a fine-grained powder (2-5 microns).

2- Manufacture of the natural adhesive

Gum arabic, generally obtained from trees, is dissolved in lukewarm water at 50° and then appears as a natural adhesive in the form of a viscous liquid.

3- Mixing raw materials

The mixture of casuarina seeds with the viscous liquid according to a percentage of 60-40 for example to obtain 1 meter of agglomerate, it takes sixty kilos of material and 40 liters of gum arabic liquid.

The mixture makes it possible to obtain a paste of ftlaos seed particles agglomerated by the natural adhesive of 100% natural gum arabic.

4- Panel pressing

The paste obtained is shaped in a mechanical press where the mattress is compacted to the desired density and thickness. Pressing solidifies the fiiao seed particles and stabilizes the shape of the chipboard panels, the more pressure the harder the panels.

5- Drying

The panels are exposed to the sun for 72 hours before being stored and made available for different uses.

Hardboard for the manufacture of cupboards, storage units, kitchens, etc.

6- New products obtained ~A) floating parquet

By crushing in the form of fiber and not of powder the filao seed mixed with gum arabic makes it possible to manufacture thermal and sound insulation panels.

By moderately crushing the same seed it is possible to manufacture floating floors

Floating parquet is a floor covering, in wood the thickness of a floating parquet must be 2.6mm and its installation is made in floating ways, that is to say that the floor is not directly fixed to the ground.

ΒΊ sound and thermal insulation panels

The killer whale AGGLOFIL panels are made with lightly crushed seeds reducing them like cigarette tobacco it becomes a thermal insulation product in addition to being recyclable it lets the walls breathe. It should be noted that this product not only thermal and protects against noise in addition it is fire resistant.

5) EXPERTISE AND COMPARISON WITH THE AGGLOMERE CLASSIC

Agglofil is an agglomerate (without wood)

i) Its composition ίο Casuarina seeds • Arabic gum binder ii) Its performance

a) Density 0.995 agglomerate 3c=0.883

Both float on water

Chipboard is denser than classic chipboard

The comparative tests were made between:

- 60/40 chipboard

-A 3-layer chipboard

-a simple chipboard

25 Chipboard 60/40 3-layer chipboard Simple agglomeration HARDNESS — — Lower SHOCK RESISTANCE Lower DRILLING — — Superior

FIRE RESISTANCE

By exposure to flame-combustion

AGGLOFIL SINGLE AGGLOBAL 1 minute Stop Stop 2 minutes Stop Flame 30 3 minutes _____ Stop Flame 2'______________

Agglofil is fire resistant compared to conventional chipboard.
