Melamine board, the full name is melamine-impregnated plastic film paper veneer.
Soak papers of different colors or textures in melamine resin adhesive, and after drying to a certain extent, spread them on the surface of particleboard, moisture-proof board, medium-density fiberboard, plywood, blockboard, multi-layer board or other hard fiberboard, heat Pressed, and laminate was born.
What is the difference between melamine board and composite board?
Melamine is laminate, but not all laminate is melamine. When melamine laminates are manufactured, they are made by molding a melamine/formaldehyde combination into a durable plastic sheet.
This is done by applying a certain amount of pressure per square inch to the laminate. However, the pressure applied can change the classification of the laminate. Melamine is a low-pressure laminate (LPL) because it is made under pressure of 300-500 pounds per square inch. High Pressure Laminate (HPL), also known as Formica, weighs over 1400 lbs.
Steps to Manufacturing Laminate:
Step 1 Raw Materials
Decorative plastic laminates are made from resins that react with aldehydes during the thermosetting process. The resin is laminated on a kraft paper layer with a decorative sheet on top.
Laminate consists of three layers:
A bottom layer of brown paper coated with phenolic resin, a second layer of paper decorated with the desired pattern, and a third layer.
Step 2 impregnated paper
The process begins by dipping the paper strips in resin.
Decorative plastic laminates are available in different grades or thicknesses, depending on their intended use. There may be 7-18 layers of paper combined to make the final paper.
The bottom layer is kraft paper. The paper comes in ribbons of varying widths, usually three, four, or five feet. The kraft paper is passed through a “tub” or barrel containing phenolic resin.
The top layer of paper is translucent. This is run through a vat of melamine resin. The layer directly below is the decoration layer. This is a paper with a printed color or design that shows the desired surface pattern through the transparent top layer. This paper also goes through the melamine barrel.
Step 3. Drying
The paper before resin treatment is flexible and easy to tear, while the paper after treatment is hard and brittle.
The resin-impregnated sheet is then placed in a drying chamber. Next, they are cut and stacked in layers. The clear and decorative layers are on top of the brown paper.
Step 4. Thermoset
3 The plies are then loaded onto a hydraulic flatbed press for final curing.
Thermoset converts the paper into a single, rigid laminate.
Step 5. Finishing
The board is trimmed to size and sanded, then cut to size and shape.
Step 6. Assembly
The finished laminate is combined with MDF particleboard or plywood etc.
Step 7.Composure Dry Pressing and Hot Pressing
Step 8. Quality Control
Step 9. Packing and Stacking
