1. Particleboard is a kind of artificial material made by crushing the residues of wood processing, sawdust, etc. plate. Because its section is similar to honeycomb, it is called particleboard. Advantages: The inside is a cross-staggered structure of particles, so the nail holding force is good, the lateral bearing capacity is good, the cutting cost is lower than that of MDF, although the formaldehyde content is higher than that of MDF, the price is relatively cheap. According to the difference between imported and domestic finishes and thickness, the price of each sheet ranges from 60 to 160 yuan) Disadvantages: Due to the easy production method, the quality varies greatly, it is difficult to distinguish, the bending resistance and tensile resistance are poor, and the density is loose. Easy to loosen. 2. Medium density board This kind of wood-based board is made of wood fiber or other plant fiber as raw material, and is formed by high temperature and high pressure with urethane resin or other suitable adhesive, so it is called MDF. It is called MDF with a density of 0.5~0.88g/cm3. The density lower than 0.5 is generally called fiberboard, and the density higher than 0.88 is called high density board. Advantages: good physical properties, uniform material, mechanical properties close to wood, there is no dehydration problem, so it will not be deformed by moisture. Some surfaces are decorated with trimerized hydrogen ammonia, which has the characteristics of moisture resistance, corrosion resistance, wear resistance, high temperature resistance, etc., no post-treatment is required, and the formaldehyde content is low. Disadvantages: high processing accuracy and process requirements; poor nail holding force; not suitable for processing on the decoration site; high cost. According to the difference between imported and domestic veneer and thickness, the price of each sheet ranges from 80 yuan to 200 yuan. 3. The difference between particle board and density board The raw material of particle board is not completely pulverized into fibers, but pulverized into granules, which is generally called shavings, and then added with glue and pressed together, while MDF is made of The wood raw materials are completely crushed into fibers and then glued together. The density of particleboard is relatively close to that of medium density fiberboard, but since particleboard is made of shavings material and pressed with adhesive, its density is not uniform, low in the middle and high at both ends. 4. Blockboard, commonly known as large core board, is a special sandwich plywood, which is formed by parallel arrangement of wooden strips of the same thickness and different lengths and tightly spliced together. The vertical flexural compressive strength of the large core board is poor, but the lateral flexural compressive strength is higher. V panel furniture is classified according to surface decoration. At present, typical flat decoration materials on the market include veneer, decorative paper, impregnated paper, PVC, etc. 5
Advantages and disadvantages of rubber wood furniture With the soaring price of solid wood furniture and the lack of various high-grade woods, rubber wood has gradually entered people's attention. As a mid-range furniture, what are the advantages and disadvantages of rubber wood furniture? What are the advantages and disadvantages of rubber wood furniture? advantage
1. Rubber wood itself is not a precious wood. It is used by rubber farmers in Southeast Asia to make building materials and furniture after cutting down the old wood after cutting the gum. The growth cycle is not long, generally ten years can become a material, so it can be said to be inexhaustible.
2. This wood is not easy to crack in dry northern areas.
3. Rubber wood has good plasticity in the process of making furniture, so it can be suitable for making products with beautiful shapes and soft curves.
4. Rubber wood furniture has good wood feeling, beautiful texture and uniform texture.
5. Light color, easy to color, can accept all types of color dyeing and coating, easy to match with other wood color tone, good paint coating performance.
6. Good hardness, natural high-strength wear resistance, especially suitable for stairs, floors, tables, countertops, etc.
Disadvantages of rubber wood furniture
1. Rubber wood is a tropical tree species, and it is a poor tree in terms of hardness, material, texture and performance.
2. Rubber wood has a peculiar smell. Because of its high sugar content, it is easy to change color, decay and moth-eaten. It is not easy to dry, not wear-resistant, easy to crack, easy to bend and deform, easy to process wood, and easy to deform in plate processing.
