What you must know about water-based boards!

1.

Water-based board is mainly composed of wood material or wood fiber and water-based polyurethane adhesive.

2.

In today's global concern about climate change, the protection of forests has become a consensus of mankind, while the world's recoverable forest resources are decreasing, and social and economic development is increasing the demand for wood and its products, making full use of artificial fast-growing commercial forests, forest cultivation and logging surplus.

With the development of society and the guidance of national policies, consumers are increasingly pursuing the environmental protection performance of artificial boards

The main factors affecting the environmental protection of wood-based panels are the adhesives (urea-formaldehyde or phenolic adhesives) and the coatings used for coating.

Water-based sheet was first proposed by water-based Ketian, an advocate of non-toxic home improvement.

 1.

The full name of water-based decorative veneer is water-based decorative veneer veneer wood-based panel.

The water-based decorative panel is a natural wood pattern, with a natural texture pattern, large variability and irregularity
.
It not only has the beautiful pattern of wood, but also achieves full utilization of wood resources and reduces costs
.
According to the type of wood, water-based veneer generally includes teak veneer, black walnut veneer, ebony veneer, rosewood veneer, ash veneer,
etc.

 2.
Water-based blockboard 

The water-based blockboard is made of high-quality natural planks after heat treatment (ie, drying in a drying room), and then processed into wood strips of a certain size, which are combed and spliced ​​by an automatic splicing machine to form a core, and the core after splicing is applied Water-based polyurethane adhesive, covered with high-quality veneer on both sides, and then sawed after being glued by cold and hot presses
.

Its natural wood characteristics are more suitable for the natural needs of human beings.
It has the characteristics of light weight, easy processing, good nail holding power and not easy to deform.
It is an ideal wood for interior decoration and advanced furniture manufacturing
.
According to the material of the core board, water-based blockboard generally includes Malacca core blockboard, fir core blockboard and so on
.

 3.
Water-based plywood 

Water-based plywood is a three-layer or multi-layered material made of wood segments that are cut into veneers or sliced ​​into veneers, and then glued with water-based polyurethane adhesives.
The fiber directions of adjacent layers of veneers are glued perpendicular to each other
.

Water-based plywood is one of the commonly used materials for furniture, and can also be used in aircraft, ships, trains, automobiles, buildings and packaging boxes
.
Its physical and mechanical properties in the vertical and horizontal directions are small, which can improve the utilization rate of wood and is a main way to save wood
.
According to the material of veneer, water-based plywood generally includes eucalyptus core plywood, poplar core plywood, miscellaneous wood core plywood,
etc.

 4.
Water-based wood incense board 

Water-based wood fragrant board is to pave the polymer film of different colors and textures on the surface of water-based plywood, water-based blockboard or other water-based hard fiberboard, and apply water-based polyurethane adhesive through cold pressing, hot pressing, health care and other processes.
Refined decorative panels
.

The water-based wood fragrant board has a natural texture and a clear wood grain, which can be comparable to the log
.
It has the characteristics of self-extinguishing, washable, wear-resistant, moisture-proof, anti-corrosion, acid-proof, alkali-proof, and non-stick dust.
The labor cost of painting, and the construction time is shortened
.
Water-based wood incense board is a new generation of paint-free decorative materials that are green, non-toxic, odorless and non-polluting
.

Water-based wood incense board has an increasing market share in the interior decoration and furniture industry, and can be used in cloakrooms, wall cabinets, wall decoration, ceilings, wardrobes, bookcases, tables and chairs, shoe cabinets, bathroom cabinets, wine cabinets, etc.
furniture
.
According to the material of the core board, the water-based wood fragrant boards generally include fir core wood fragrant boards, golden fir core wood fragrant boards and so on
.

 5.
Water-based density board 

Water-based MDF is a kind of artificial board that is made of logs as raw materials, after chipping, fiber separation and drying, water-based polyurethane adhesive is applied, and then formed by high temperature hot pressing
.

The performance characteristics of water-based density board:

(1) The water-based density board is environmentally friendly and non-toxic, and the formaldehyde emission is detected in accordance with the national standard GB/T 11718-2009 "Medium Density Board Fiberboard".
The result is that it is not detected, and it belongs to the green board;

(2) The surface of the water-based density board is smooth and flat, the material is fine, the performance is stable, and the edge is firm, which can be suitable for a variety of finishing processes
.
(3) The internal fiber structure of the water-based density board is uniform, and the fibers are bonded by the water-based polyurethane adhesive, and the bonding strength is high, so it has high static bending strength, elastic modulus, internal bonding strength, surface bonding strength and other physical properties indicators Good performance, suitable for sawing, drilling, grooving, tenoning, engraving,
etc.

(4) Due to the use of water-based polyurethane adhesive hot-pressing, the moisture-proof performance is better than other MDF using urea-formaldehyde glue hot-pressing
.

The main uses of water-based MDF:

Water-based density boards can be widely used in many fields according to their different densities and different functions
.
For example, in terms of interior decoration, it can manufacture wardrobes, cabinets, door panels, water-based laminate floors, wall panels, carved panels,
etc.
After special processing, it can also produce waterproof board, flame retardant board, vehicle cabin partition, housing non-load-bearing partition, audio, interior decoration of luxury cars,
etc.

Water-based MDF will be well received by more and more users because of its high environmental protection requirements, excellent physical and mechanical properties, and wide application fields
.

Fourth, purchasing skills

(1) The surface should be smooth and flat, free of defects, uniform thickness, and no overlapping and de-core phenomenon;

(2) Whether the percussion sound is uniform, if the sound gap is large, there may be holes inside, indicating that there is a certain quality problem;

(3) Good hand feeling, no wavy lines, smooth and dry;

(4) The fragrant log smell, no pungent smell emitted by harmful substances such as formaldehyde;

(5) Saw the whole board to see whether the internal structure is dense and whether there are metamorphic eggs;

(6) Whether there is a formal manufacturer's trademark, certificate of conformity, production address after-sales service telephone number, anti-counterfeiting logo, etc.
;

5.
Disadvantages

(1) Due to the high requirements for the production process and the strict control of the production process, relevant measures for the protection of finished products
.
The cost is higher than that of conventional artificial boards, so the price is high;

(2) The industry adage "no aldehyde does not form glue" has a certain restrictive influence on the development of water-based boards, and it takes a certain amount of time to break the traditional concept;

(3) The core technology of water-based boards is in the hands of a few manufacturers, which has a certain restrictive influence on the promotion and development of water-based boards;

(4) The confusion of the traditional man-made board operator restricts the rapid development of water-based boards;

(5) The market competition is fierce, and many manufacturers adopt vicious competition and shoddy products
.

6.
Matters needing attention

(1) The water-based sheet should be placed flat in a dry place, not upright, and protected from moisture, wetness, and exposure to the sun;

(2) Do not mix and stack water-based sheets with formaldehyde-containing products to avoid cross-contamination causing excessive formaldehyde;

(3) Before decoration, check whether the wall is dry and do a good job of moisture-proofing the wall
