Currently there are 1,200 processing enterprises, the lumber business, in which over 300 companies have exports, Vietnam is targeting exports of timber reach $ 1.5 billion / year, including plywood people would create major role. Products furniture: tables, chairs, beds, wardrobes, kitchen cabinets, partitions, floors, walls, ceiling ... made from artificial plywood is suitable for home furniture, office, school , hotels, restaurants, cultural and sporting offer ...
According to Pham Quang Hien (General Director of the Vietnam Forestry Corporation), artificial plywood products produced and widely used in Vietnam currently includes three main categories: fiber boards, planks, particle board .. .
Particle Board (PB) is a synthetic wood made from plantation wood (eucalyptus, acacia, rubber ...), high mechanical strength, size large surface area, rich in variety. Face covered with the boards pasted decorative material difference: melamine, veneer (veneer) ...
Particle board is the main material used for interior decoration, furniture manufacturing family, work. Particle board is manufactured by molding process wood chips were mixed glue, like MDF, but the wood is milled into chips, so they have lower quality MDF.
Technology coated surface and edge glued board meets many requirements of shapes and sizes, including 2 types of products: plain particle board and MFC. Particle board is plain common type on the market, often using veneer, painted, or covered with PU. With the MFC, the two sides are coated with melamine to create beauty, moisture and scratches.
The more particle board producer in the world are: Malaysia, Vietnam, New Zealand, Thailand and Australia. Where the particle board production in Vietnam is currently Taiyuan Particle board plant, with a capacity of 16,500 m3 of product design / year, applied the quality management system ISO 9001-2000, equipped with technology great, the product ships with thickness from 8mm to 32 mm.
Fibreboard MDF (aka pressed wood) timber of artificial high mechanical strength, large size, suitable for furniture production technology in the interior tropical climates. MDF is widely used in many fields of manufacturing furniture, interior decoration and construction.
MDF is produced through the process of wood fibers pressed puree mixed glue, the proportion of 520-850kg / m3, depending on the quality requirements, timber thickness. On the market there are three main types: smooth, water-resistant, melamine.
Plain MDF is the most common type, often using veneer, painted or covered with PU. MDF is water resistant MDF kind of smooth, water-resistant glue is mixed in the production process, often used in place of potentially exposed to water or high humidity such as doors, furniture in the kitchen. Melamine MDF: MDF sides are coated with melamine to create beauty, moisture and scratches.
Planks (also called laminated wood) are manufactured from the raw material is wood plantations. The small wood treated autoclaved on line advanced technology, modern equipment, wood sawing, planing, milling, compound, pressing, rubbing and decorative coatings. Planks are widely used in the fields of furniture, interior decoration, flooring and many other products.
There are four ways laminated wood: parallel, face, edge, corner. Wood slats duplexer multi same length, width may be different, parallel pair. Wood slats face transplant including many short, at both ends of the comb-shaped sawn and then merge them into the bars of equal length, and continued graft parallel bars, so just seeing spots on the comb-shaped graft board surface, the Japanese market is very popular this grafting.
Advanced production technology of artificial wood
Artificial wood so much of our country has not been overcome disadvantages: contain toxic, easy to deform when in contact with water, flammable, or termites, cracked cup. In recent years, many people have studied, improved production technology to bring high efficiency.
Lam Dong Phuc Tran fabricated plywood factory from coffee husk, dried tobacco, rice hulls made of artificial wood products at a lower price. This board processing technology not only helps farmers increase income but also supports solving environmental problems.
Mr. Nguyen Van Thanh for a bunch of new technologies in manufacturing plywood, promises a breakthrough for Vietnam's wood exports. With thermosetting plastics His Thanh, plywood products have improved the quality, ahead of both the technology of many countries around the world. Successfully produced fireproof coats is also an important step forward, bringing superior properties than any primer by importing any character against fire and completely harmless.
An industry seemingly simple but extremely scientific: put the timber type is of poor quality (fast section absorbent, easy bending ...) on average reservoir pressure, up to 180 ° C temperature, pressure reaches 5 at. High temperatures cause the plastic body is liquefied wood, elastic fibers made of cellulose. Then a sudden discharge of steam and take thermoset resin colloid on average, penetrates thermoset resins, cellulose fiber, wood hardening create products of equal quality natural precious wood.
Currently, most of the plywood products from Vietnam, Southeast Asia and exported to markets in Europe and America for failing to meet the technical standards. So in order to promote exports, achieving export target set by the Government of timber, timber export enterprises should strengthen research on new technologies for application in production, overcoming the disadvantages of wood products Vietnam's artificial.
