Hdhmr Panels

THE BOARDS ARE BROADLY CLASSIFIED AS PLYBOARD, BLOCK BOARD, PARTICAL BOARD AND MDF BOARD. HDHMR BOARD IS A TYPE OF MDF BOARD.

HOW IS THIS MADE ? – AN HDHMR BOARD IS MADE USING A HOMOGENOUS MANUFACTURING PROCESS THAT COMBINES FIBRE CHIPS AND FOREST WOOD WASTE. THE FIBRE CHIPS ARE PRESSED TOGEHER TO FORM A SINGLE LAYER, AFTER WHICH SMALL AMOUNTS OF WOOD ARE REMOVED TO CREATE A MORE STURDY BOARD WITH HIGHER DENSITY.

THE FIRST MAIN ATTRACTIVE THING ABOUT HDHMR BOARD WE WANT TO FOCUS IS, WATER RESISTANCE. AS YOU CAN SEE IN THE NAME THE TERM, HIGH DENSITY IS ACHIEVED THROUGH THE COMBINATION OF THE HARD WOOD PARTICLE BOARD ALONG WITH THE SPECIAL GLUE PRESSING TECHNIQUE. THESE HARDWOOD PARTICLES WHEN PRESSED THROUGH THE GLUE, THEY FORM A UNIQUE WATER RESISTANCE LAYER THROUGH THE BOARD. DUE TO THIS FEATURE, THESE BOARDS WILL TAKE OVER PLYWOOD IN KITCHEN FURNITURE SOON AND CAN BE USED AS LAMINATED FLOORING.

DUE TO PRESSING TECHNIQUE SMALL UNUSABLE PARTICLE GET REMOVED FROM THESE BOARDS, WHICH MAKES THEM TERMITE FREE TOO. IN PLYWOOD MAKING PROCESS SOME CONTENT OF WOOD GET STUCK, WHICH PROVIDE EASY ACCESS TO TERMITES IN TERMS OF FOOD; BUT IF YOU ARE USING HDHMR BOARD THAN THERE IS NO NEED TO WORRY ABOUT TERMITES. DUE TO PRESSING TECHNIQUE OF HDHMR BOARD, SEVERAL SMALL FIBERS OF WOOD COMBINES TILL THE TIME IT REQUIRED DENSITY IS NOT ACHIEVED.

DISADVANTAGE

AFTER LONG-TERM USE, SOME HDHMR BOARDS MIGHT BEND AND LOSE SHAPE.

THE KEY APPLICATION AREAS OF HDHMR

•KITCHEN SHUTTERS •FURNITURE WHERE RISK OF MOISTURE EXIST •DOORSHUTTERS •PACKING INDUSTRY •SHOE HEEL• PARTITIONS •OUTDOOR FIXTURES LIKE ELECTION CUTOUTS OR SIMILAR APPLICATIONS •WALL PANELING.

PLYWOOD

1.PLYWOOD IS MADE WITH WOOD VENEERS WHICH ARE LAID IN SUCH A MANNER THAT GRAINS OF ADJACENT LAYERS ARE IN PERPENDICULAR DIRECTION TO EACH OTHER.

2. PLYWOOD USES VENEERS PEALED FROM THE TRUNK OF MATURE HARD WOOD TREES ONLY. HENCE 50% OF THE TREE REMAINS UNUSED OR WASTED.

3. SINCE MADE FROM VENEERS, DISADVANTAGES OF WOOD LIKE TERMITE/BORER ATTACK AND UNCONTROLLED EXPANSION/CONTRACTION REMAINS THERE.

4. TRUE THICKNESS IS NOT AVAILABLE AS CORE & FACE THICKNESS VARY WITH THE PEELING & THE CAN BE CONTROLLED ONLY TO A CERTAIN EXTENT.

5. OVER THE PASSAGE OF TIME, PLYWOOD LAYERS TENDS TO PEEL OFF FROM THE EDGES

6.PLYWOOD & BLOCK BOARD TEND TO HAVE DENSITY VARIATION DUE THE VARIABLE GRAIN DENSITY, HENCE HAS VARIED PHYSICAL & MECHANICAL PROPERTIES. HAS CORE GAPS.

7.PLYWOOD HAS A SURFACE THAT NEEDS TO BE FINISHED/PREPARED LIKE SANDING AND PUTTY FILLING BEFORE PAINTING/ POLISHING OR OTHER FINISHING PROCESSES .

8.DUE TO UNCONTROLLED THICKNESS VARIATION ACROSS THE BOARD AND ROUGH SURFACE, PRELAMINATION OF RESIN IMPREGNATED PAPER IS NOT POSSIBLE

9.PLYWOOD CANNOT BE CARVED OR ROUTED OR PROFILED

10.DENSITY LIES IN NORMAL MEDIUM DENSITY I.E AROUND 750 KG/M3

Hdhmr

1.HDHMR IS MADE WITH WOOD FIBRE/WOOD CHIPS AND SYNTHETIC THERMOSETTING RESIN IN A HOMOGENEOUSLY SPREAD MAT & PRESSED IN TEMPERATURE AND PRESSURE CONTROLLED PRESS.

2. HDHMR IS MADE FROM WOOD FIBRES/CHIPS THAT IS PRODUCED FROM PLANTATION WOOD, AGRICULTURAL WASTE OR FROM THE FOREST WOOD WASTE & USES 95% OF THE TREE. HENCE SAVES THE ENVIRONMENT.

3. MADE FROM FIBRES OF LIGNOCELLULOSIC MATERIALS, DURING PROCESS OF MAKING FIBRES THE WOOD CHIPS ARE STEAM COOKED RESULTING IN REMOVAL OF ALL FOOD CONTENT THEREBY MAKING IT TERMITE/BORER RESISTANT, AS THESE INSECTS ATTACK THE WOOD IN SEARCH OF FOOD ONLY.

4. TRUE THICKNESS IS AVAILABLE AS PRESSING PARAMETERS ARE PERFECT. PRECISE UNIFORMS THICKNESS CAN BE MANUFACTURED.

5. HDHMR HAS A MULTI-DIMENSIONAL BOND BETWEEN FIBRE WHICH IS STRONGER WITH HIGHER BONDING SURFACE BETWEEN FIBRES.

6.HDHMR HOMOGENEOUSLY CONSTRUCTED WITH UNIFORM SPREAD OF FIBRE/CHIPS, HENCE HAS UNIFORM PHYSICAL & MECHANICAL PROPERTIES.

7.IN HDHMR/MDF THERE’S PAINT/POLISH READY SURFACE. PASTING OF VENEER/HPL IS EASIER RESULTING SMOOTH FINISH WITHOUT ANY UNDULATION UNLIKE PLYWOOD OR BLOCK BOARD.

8.DUE TO UNIFORM THICKNESS AND SMOOTH SURFACE, PRE-LAMINATION ON HDHMR WITH RESIN IMPREGNATED PAPER GIVES A PERFECT FINISH

9.HDHMR DUE TO ITS FIBROUS HOMOGENEOUS CONSTRUCTION CAN BE PROFILED, CARVED, MOULDED, ROUTED

10DENSITY MORE THEN 850 KG/M 3 RESULTING IN BETTER COMPACTNESS AND STRENGTH
