MDF em bruto de alta resistência
Descrição
High Strength Raw MDF stands for Medium Density Fiberboard. Medium Density Fiberboard is made of plant fibers, applied with urea-formaldehyde resin or other synthetic resins, and pressed under heating and pressure conditions to form a board with a density in the range of 0.50～0.88g/cm3. Others can also be added. Suitable additives to improve the properties of the board. There is no water consumption in the production process, and it can be recycled.
MDF also known as fibreboard, is a wood-based panel made of lignocellulosic resin or other suitable adhesives. Adhesives and/or additives can be applied during the manufacturing process. The MDF has the advantages of uniform material, small difference in longitudinal and transverse strength, and is not easy to crack, and has wide application. It takes about 2.5 to 3 cubic meters of wood to make 1 cubic meter of MDF which can replace 3 cubic meters of sawn timber or 5 cubic meters of logs. The development of fiberboard production is an effective way to comprehensively utilize wood resources.
High-strength protective layer, not only high scratch resistance, high wear resistance, but also high moisture resistance. The shape, color and surface texture of MDF create unlimited space for the design. The closed powder package greatly reduces the residual formaldehyde emission in the MDF, and bacteria are not easy to grow. MDF can effectively remove formaldehyde in the board at the same time, meeting environmental protection standards. It effectively achieves energy saving and emission reduction.

Processo de produção
RAW MATERIALS STORAGE
We have several warehouses to store all our Raw Materials like Poplar Veneer, Hardwood Veneer, Sapelli/Bintangor/Okoume/Pencil Cedar/Pine Face/Back, etc. Once new raw materials delivered into our warehouses, our workers will inspect all and place different grade ram materials into different warehouses.
RAW MATERIALS PRETREATMENT
Once production started, our workers will pretreat the raw materials including the sides joint, gluing.
VENEERS ASSEMBLE
Our workers will assemble the wood veneers one layer by one layer on the assembly line. Like the 18MM will consist of 11 layers wood veneers.
RAW BOARDS PREPRESS
After Veneer Assemble Process, all the Raw Boards need to be prepressed by Cold Press Machine. So that the Raw Boards can be shaped into Raw Plywood. This process need at least 2 hours.
RAW PYWOOD HOT PRESS
Shaped Raw Plywood will be laminated by Hot Press Machine. This process need at least 1 hour. After Hot Press, the Raw Plywood bonding will be strong.
RAW PYWOOD REPATCHING & PUTTYING
This process is to fill the gap on the surface of raw plywood.
RAW PYWOOD SANDING
Put the Raw Plywood into Sanding Machine. After sanding, the raw plywood surface become smooth, and thickness will be even also.
FACE/BACK VENEER ASSEMBLE
Raw Plywood will be glued firstly. Then workers will place the face/back veneer like Sapelli /Bintangor/Okoume/Pencil Cedar on the both sides of raw plywood.
COLD PRESS
After Face/Back Veneer Assemble Process, plywood will be placed into Cold Press Machine again. So that the Face/Back Veneer will bond with the raw plywood initialy. This process need at least 1 hour.
LAMINATED PYWOOD HOT PRESS
This process need at least 30 minutes. After second Hot Press, Face/Back Veneer will bond with the raw plywood strong.
CUTTING & POLISHING
All plywood will be cut into standard size like1220X2440MM. Then plywood will be polished gain to make the face/back smooth.
INSPECTION & PACKING
Inspect boards for defects (e.g., cracks, uneven density, surface imperfections). Grade the qualified boards based on quality standards. Stack and package the boards for storage or shipment.
