1. Requirements for customized solid wood for hotel furniture
（1) If the product is marked as all-rosewood furniture, all parts of the product must be solid wood furniture made of rosewood, except for the mirror backboard.
（2）If the product is marked as rosewood furniture, the external parts of the product must be solid rosewood. The interior, back, and hidden parts of the product can be made of solid wood furniture made of other tree species.
（3）For double-clad frame furniture, the tree species used on the exterior of the product should be similar in texture. There should be no obvious difference in the materials used for the same glue components. Coniferous and broad-leaf wood must not be mixed. The plywood used on the exterior should be of the same tree species. There are no restrictions on the species of trees used.
（4）The moisture content of wood is a crucial indicator of the quality of wooden furniture. There is a big difference in the average annual wood equilibrium moisture content between the south and the north. The south is generally 16%-18%, the north is generally 12%-14%, and the south is generally 12%-14%. , the average in the north is about 15%. When inspecting the product, the annual average wood equilibrium moisture content + W1% in the area where the product is located is the standard value for measurement. If there are other requirements for the wood moisture content, it should be clearly stated in the order contract.
2. Material requirements for customized artificial panels for hotel furniture
（1)Plywood, also known as plywood, is commonly known as a thin core board in the industry. It is made by rotary cutting logs into veneers or wood square planing into thin wood chips, and then gluing them with adhesive. It is made of three or more layers of one-millimeter thick veneers or thin sheets glued and hot pressed. Usually, an odd number of layers of veneers are used, and the wood fibers of adjacent layers of veneers are arranged vertically and glued to each other.
（2) Medium-density fiberboard: Made of wood fiber or other plant fibers as raw materials, urea-formaldehyde resin or other applicable adhesives are applied to make boards with a density of 0.5--0.88.
（3) Particleboard: A type of artificial board made by processing wood or non-wood plant fiber raw materials into shavings (or scraps), applying adhesive (and other additives) to form a blank and hot pressing.
(4)The average density of each sheet shall not exceed ±10% of the nominal density. The density deviation р deviation (%) is calculated according to the following formula: accurate to 0.1%; р deviation = (р average--р nominal)/р nominal * 100; In the formula: P average - the arithmetic mean of the density of each plate specimen, g/cm3; р nominal - the nominal density, g/m.
(5)The ex-factory moisture content of the board should be 4%--13%, and the water absorption thickness expansion rate should not exceed 12%.
(6)The amount of free formaldehyde released in the board is less than or equal to 5mg/100g, and the total amount of formaldehyde that can be extracted per 100g of weight must not exceed 70mg.
(7)Environmental protection grade of the board: E0 level is the highest international health standard; E1 level is the national mandatory health standard; E2 standard board must undergo strict finishing treatment before it can be used.
A.E0 level: The E0 level environmental protection standard means that the formaldehyde emission index of particleboard is not greater than 5mg/100g
B.E1 level: The E1 level environmental protection standard means that the formaldehyde emission index of particleboard is not more than 9mg/100g
C.E2 level: The E2 level environmental protection standard means that the formaldehyde emission index of particleboard is not more than 30mg/100g
3. Requirements for a customized natural wood veneer for hotel furniture
(1)The thickness of the A-grade veneer must be more than 0.45mm, which is reserved according to the size of the board. The length of the veneer is required to be about 2.6 meters; the width of 20cm or more must be 80% or more, and the quantity of 15cm cannot exceed 20%.
(2)The mountain pattern is centered, with no white edges, no dead knots or dead knot perforations, no resin sacs, no serious mineral lines, serious black spots, serious black stems, no fracture lines; no blue spots, mildew spots, no damage or incompleteness Sandwich leather, no twill, semi-pattern; no knots, no tiger spots, no freckles, no eyes; clear texture, smooth surface without wrinkles, no obvious color difference, the natural color difference is allowed but must be consistent. The diameter of the joints is ≤3mm and they are dispersedly distributed, and rows are not allowed. Straight-grain veneer has smooth, straight, and natural texture, with even grain spacing. The surface of the veneer is smooth and wrinkle-free.
(3)Grade B veneer: no dead knots or dead knot perforations, no damaged or incomplete skin, no resin pockets, severe black spots, severe black veins, blue spots, mildew spots, and discoloration. Twills, mineral lines, and scattered joints are allowed; the wood grain texture is clear, slight tree shadows are allowed, and slight black scars, black veins, and scars are allowed, but pay attention to the location of use. (Such as the back panel, the reverse side of the laminate, and other invisible parts) The width of the white edge does not exceed 10 mm; slight wrinkles are allowed on the surface.
(4)The width tolerance of the veneer is allowed to be within +10mm-20mmM, the thickness tolerance is allowed to be within +0.1mm, and the moisture content of the veneer is ≤14%.
(5)Under normal circumstances, A-grade veneer is used for product panels, door panels, bed screens, and other places exposed to light, while B-grade veneer is used for the back of the product or other parts that are not exposed to light.
