What are the environmental standards for various types of decorative panels? In accordance with China's environmental standards, according to the concept of formaldehyde release limit, the formaldehyde limit level in the decoration plate is divided into three levels, namely, E2 ≤ 5.0mg / L, E1 ≤ 1.5mg / L, E0 ≤ 0.5mg / L. In our country, decoration plate to achieve the E2 level can be, that is, the E2, E1 and E0 level. The boards can be called environmentally friendly boards, but because of the progress of consumer awareness of environmental protection, the market is now mostly seen on the market E1 level or even E0 level boards.

E0 scale is the promise of formaldehyde in the plate, but not more than 0.5mg/L, which is the highest upper limit; the lower limit should be the highest content of wood itself aldehyde (wood itself aldehyde content is generally 0.12mg/L-0.04mg/L), that is, the lower limit is 0.12mg/L.

'Zero formaldehyde', that is, the selection of materials without aldehydes, the process of the production reaction does not produce aldehydes; the reaction process also does not produce aldehydes; the production reaction does not produce aldehyde. Aldehyde is not produced in the production reaction process; the environment does not bring any pollution and harm to the production staff. From this we can give 'zero formaldehyde' plate such a definition: the free aldehyde in the plate is less than that is the wood itself aldehyde content (generally in 0.04mg / L-0.12mg / L).' Zero formaldehyde' sheet and E0 is not the same thing, 'zero formaldehyde' sheet in principle, higher than E0 a level.

Home improvement commonly used several types of panels

Panels can be broadly divided into density board, particle board, veneer board, woodworking board, plywood, melamine panels, integrated wood, pine board, formaldehyde-free strawboard and other 9 types, but because of the different requirements of the family, the current market commonly used panels are mainly woodworking boards, integrated wood ( finger-joined boards), as well as formaldehyde-free strawboards. Finger-joined board), and a small amount of melamine board, veneer board (molded board), density board, particle board, veneer board and plywood, home improvement can be purchased according to the use of different types of panels.

They generally have a fixed size of about 2440 × 1200mm, that is to say, each area of about 2.88 square meters, homeowners can be based on the actual number of family use roughly calculate how many of these sheets are needed. At present, most families only need to purchase woodworking boards and fingerboards are enough, and from the environmental level, quality and practicality, woodworking boards and fingerboards are better than several other types of panels.

Woodworking board

The scientific name of the joinery. There are two pieces of veneer in the middle of the adhesive splicing board and become. By the thickness of the same, the length of the wood parallel arrangement, and close splicing and become, generally for the five-layer structure.

Use: making door sets, window sets or ceiling, and departmental closets.

Specifications: the thickness of about 1.2CM-2.5CM, home normal should be used for 1.6CM-2.0CM thickness, if you do a large cabinet door, etc. to use a thicker. From the environmental level up to the general family use E1 level can be, its price to grade and core material of the different price difference is relatively large.

Environmental level: the big brands common E1, E0, zero formaldehyde; small brands also have E2 level plate.

Buy: the splicing of the wood core also have hand splicing and machine splicing, good woodworking board in addition to environmental requirements, the wood core should be tight, there is no open space for good. This can be seen from the sawed section.

Integration of wood (fingerboard)

Also known as plywood, the market is common with poplar or cedar using finger-joined, notched joints and other ways of splicing up the board, using direct also known as fingerboard.

Use: the utilization rate of integrated panels is high, good processing capabilities, can be directly manufactured into straight shape and curved shape, natural and beautiful, mainly used for the production of cabinets.

Specifications: the thickness is generally 18mm, there are also 16mm.

Environmental level: the big brands common E1, E0, zero formaldehyde; small brands also have E2 level plate.

Buy: Generally speaking, a good fingerboard with fewer scars, wood color average rounded, tight and dense interface. Do not use the thickness of the board price is different, the general thickness is 18mm.

Melamine board

The full name is melamine impregnated with adhesive film paper market marketplace man-made boards. With different colors or textures of paper into the melamine resin adhesive soaked, and then dried to a certain degree of curing, it will be laid on the particleboard, medium density fiberboard or hard fiberboard surface, hot-pressed and made of decorative panels.

Use: can be arbitrarily imitated a variety of patterns, bright and shiny, used as a variety of man-made boards and wood veneer, hardness, wear-resistant, heat-resistant. The surface is smooth and clean, easy to maintain and clean. Do cabinet frame.

Specifications: thickness 16-20mm.

Environmental level: E1, E2 is more common.

Buy: check the side sealing, generally to 1-2mm.

Veneer

Also known as veneer panels, triple plywood, which is made of natural wood shaved or rotary cut into thin slices 0.2-1mm thick, after the patchwork pasted on the substrate material such as plywood, fiberboard, particleboard. This material has a clear texture, natural luster, and is a higher level of decorative materials.

Use: the market panel roughly teak veneer, walnut veneer, southwest birch veneer, maple veneer, ash veneer, beech veneer and so on. Generally used as partitions in the visible sector of the cabinet.

Specifications: generally 2.6-3mm

Environmental level: E1, E2 is more common.

Shopping: the price of the veneer board according to the different materials have a big difference, so the owners in the use of veneer board, must be clear about the veneer board material, grade in order to have a safe guarantee from the price and quality.

Particle Board

Also known as particle board, bagasse board, made of wood or other lignocellulosic materials made of scraps, the application of adhesive in the heat and pressure under the role of glue synthetic man-made boards, also known as scraps of board.

Use: Used in small quantities as an auxiliary material for millwork, built-in closets and display cases. The main advantage of this kind of board is the price and its cheap.

Specifications: particleboard according to the density of the product: low density (0.25 ~ 0.45 g / cm3), medium density (0.55 ~ 0.70 g / cm3) and high density (0.75 ~ 1.3 g / cm3) 3 kinds. Particleboard specifications more than 19 millimeters for the scale thickness, the common thickness of 13, 16, 19 millimeters 3 kinds.

Environmental level: E1, E2 is more common.

Buy: first look at the cross-section, the larger the particles inside the better, because the particles are large particle board with nails more firmly. Secondly, look at the environmental level.

Density board

Also known as fiberboard, is a man-made board or composite board. It is wood fiber or other plant fibers as raw materials, the application of urea-formaldehyde resin or other suitable adhesive made of man-made panels. It is not suitable for home decoration because of poor nail grip.

Use: According to its density, divided into high density board, medium density board, low density board. In foreign countries, particleboard usually refers to low-density fiberboard. A small amount is used as auxiliary materials for woodworking boards.

Specifications: the general thickness from 8-25mm, due to the different specifications of the brand is also slightly different.

Environmental level: E1, E2, E0 are

Buy: good surface cleanliness of the surface of the Density Board should be no significant particles; smooth feeling should be felt when you stroke the surface with your hand; the surface of the Density Board should be bright and smooth, the harder the board is definitely a poor-quality product.

Plywood

Also known as plywood, commonly known in the industry as fine core board. By three or more layers of 1mm thick veneer or veneer glued hot pressed. By the log rotary cut into veneer or wood planing cut into thin wood, and then glued with adhesive from three or more layers of thin sheet, three, five, seven, and other odd layers of plywood.

Use: a small amount of auxiliary materials used as carpentry boards

Specifications: plywood is generally divided into three centimeters, five centimeters, nine centimeters, 12 centimeters, 15 centimeters and 18 centimeters six specifications (1 centimeter that is, 1mm), there are 21 centimeters and 25 centimeters.

Environmental level: E1, E2 is more common.

Buy: the panel should not be broken, bruises, decay, knots, cracks, indentation, pollution, roughness and other defects; pry open the plywood with a sharp blade along the glue layer, if the glue layer is damaged and the wood is not destroyed, then the gluing quality is poor.
