Tell me about the quality of furniture.
It is an artificial board made of wood processing residues, sawdust and so on. Granulating, drying, mixing with rubber, curing agent and waterproof agent, and pressing at a certain temperature. Because its cross section resembles a honeycomb, it is called particleboard.
Advantages: the inside is cross-dispersed particles, so the nail holding force is good, the lateral bearing capacity is good, the cutting cost is lower than that of MDF, and the formaldehyde content is higher than that of MDF, but the price is relatively cheap. According to the difference of imported and domestic veneer and thickness, the price of each veneer ranges from 60 to 160 yuan).
Disadvantages: due to the simple preparation method, great quality difference, difficult to distinguish, poor bending and tensile properties, loose density and easy to loosen.
2. Medium density paperboard
This kind of artificial board is made of wood fiber or other plant fiber as raw material and molded by urea-formaldehyde resin or other suitable adhesive at high temperature and high pressure, so it is called density board. Making the medium density board with the density of 0.5-0.88g/cm3. The density below 0.5 is generally called fiberboard, and the density above 0.88 is called high-density board.
Advantages: good physical properties, uniform material, mechanical properties close to wood, no dehydration problem, so it will not be deformed by moisture. Some surfaces are decorated with melamine, which is moisture-proof, corrosion-resistant, wear-resistant and high temperature-resistant, and does not need post-treatment, so the formaldehyde content is low.
Disadvantages: high machining accuracy and process requirements; Poor nail grip; Not suitable for processing at the decoration site; The cost is high. According to the difference and thickness between imported veneer and domestic veneer, the price of each veneer ranges from 80 yuan to 200 yuan.
3, the difference between particleboard and density board
The raw materials of wood shavings are not completely crushed into fibers, but crushed into particles, commonly called shavings, and then glued and pressed together, while density boards are made by completely crushing wood raw materials into fibers and then glued and pressed together.
The density of particleboard is close to that of medium density fiberboard, but because particleboard is made of wood shavings and adhesive, the density is uneven, and the middle is low and the two ends are high.
4. Core plywood
Commonly known as large core board, it is a special sandwich plywood, which is made up of wood strips with the same thickness and different lengths arranged in parallel and closely spliced. The vertical bending and compressive strength of large core board is poor, and the transverse bending and compressive strength is high.
V-type panel furniture is classified according to surface decoration.
At present, the typical plane decorative materials on the market are veneer, decorative paper, impregnated paper, PVC and so on.
