Material basis for the development of new materials is both high-tech , but also an important condition for the transformation and upgrading of traditional industries . Therefore , all the world's industrialized countries attach great importance to the research, development and application of new materials as part of the key technologies. As the United States has been the Materials Science and Technology as an important area of ​​research ; Germany next century materials research program Matech; Japan as the material technology as the lifeline of technological development .

New material means for the high-tech , high performance, new uses and new roles for each special structural and functional materials , including fine ceramics , carbon fibers, plastics , amorphous materials and fine chemical products.

1. The basic principles of furniture materials

Any piece of furniture by the material, structure , appearance, form and function composed of four elements which constitute the material is the material basis of furniture , in the history of furniture from the material used in furniture can reflect the prevailing productivity level of development . Primitive society , people use stone , wood, leather and other natural materials as the materials, the furniture is also very primitive, rudimentary. When there smelting technology , it is applied again on the metal material of furniture ; application with the invention of plastic , plastic furniture appeared ; Now the material has been used in the furniture is very rich , in addition to the commonly used wood, metal, plastic , also there are rattan, bamboo , glass , rubber, textiles, decorative plates , leather, sponge , etc. However, not any material can be used in furniture production, furniture, materials, applications have a certain selectivity , the major factors which should be considered are as follows :

1.1 processing technology .

Materials processing technology directly affects the production of furniture . For wood materials, in the process , taking into account their produce affected by moisture condensation swelling resistance, such as fissile and porous . Plastic materials to take into account its ductility , thermoplastic deformation. To take into account the glass material of thermal brittleness and hardness .

1.2 texture and appearance quality.

Material determines the texture and texture feel special appearance quality of the product. Wood is a natural material , natural texture , beautiful , vivid, feel good, and easy processing , coloring , is the production of furniture, the finest materials . Plastics and synthetic materials with a variety of natural materials simulate the characteristics of texture and good color performance, but its easy to aging, susceptible to thermal deformation, with this production of furniture , its life and use restricted .

1.3 economy.

Furniture materials economy including the price of materials, materials processing labor consumption , utilization and material source material richness. Although wood has a natural texture , etc., but with the increase in demand , timber volume declining, increasingly scarce resource , similar to wood material , economic and beautiful materials will be widely used in furniture production.

1.4 strength.

Strength to consider the holding force and anti- split performance and elastic modulus.

1.5 Surface decorative properties .

Under normal circumstances, the performance of surface decoration is the feasibility of its finishing , stickers , carving , coloring , hot , baked and other decorations .

1.6 environmental protection.

Green products (Green Product, DP) or called environmental coordinating products (Environmental Conscious Product, ECP) ​​is defined relative to traditional products concerned , the main features are as follows :

Green furniture product refers to the protection of the environment and environmental resources as the core concept and design of the product can be removed and decomposition products , their components through the renovation process can be reused.

Green furniture design that is thinking over the entire product life cycle ( design, manufacture, transportation , sale, use or consumption , waste disposal ) , focusing on the environmental attributes of products considered ( removable , recyclability , protect resistance, reusability , etc. ) , and as a design goal , to meet the requirements of environmental goals while protecting the product should function , life, quality and so on.

Green products follow the 4R

1.6.1 Regrow - make full use of solar and other renewable resources, such as fast-growing wood, bamboo and other plant fiber resources.

1.6.2 Reduce - reduce the entropy principle and asked to use less raw material and energy inputs to achieve the intended economic purpose , namely the waste generated in the production process , emissions , less waste , does not pollute the environment, production low energy consumption.

1.6.3Reuse - recycling principles in the manufacture of packaging containers reused to consider the issue , producers should be treated as a product and its packaging to daily life appliances designed so that it can be used repeatedly, rather than run after the throw.

1.6.4 Recycle - recirculation principle , which is used after the completion of the article , a resource can be reused again and not into the garbage thrown away .
