Anhui, China: The Hefei Research Institute of Materials Science, Chinese Academy of Sciences, has adopted a self-developed modification agent and a composite process on the surface of ultra-fine microspheres so that the hollow microspheres can be uniformly dispersed in the polymer matrix. The microspheres have a good interface with the matrix. Combine to obtain ultra-fine hollow bead/polymer composites with high overall performance.
It is understood that the modified PP (polypropylene) with 20% hollow microspheres has a notched impact strength increased by 80%~100% compared with that of pure PP, and the tensile modulus and bending modulus increase by more than 50%. The strength has also been increased, and only the tensile strength has remained substantially unchanged or decreased slightly. Ultrafine hollow microspheres are inorganic materials and have better wear resistance than polypropylene. In addition, it has a reflective effect on UV rays and can improve the UV resistance of composite materials.
According to reports, the use of ultra-fine hollow microspheres in fly ash modified polymers, on the one hand can play the characteristics of hollow microspheres, so that the polymer's mechanical properties, wear resistance, heat insulation, insulation properties, etc. have been greatly improved. Get high performance polymer new materials. On the other hand, the masterbatch made of such modified ultrafine hollow microbeads suitable for polypropylene or polyethylene can greatly improve the mechanical properties, wear resistance and heat insulation properties of the products through blending and addition. Reducing material costs is very suitable for injection molding products where the material has high rigidity and toughness requirements.
Dining chair is a common seat in restaurants, bars, cafes and other places for people to use when dining. According to different design styles, materials, functions and uses, dining chairs can be divided into a variety of categories. The following will be a brief introduction to the product classification of dining chairs.
First, according to the design style classification
1. Simple modern style: Simple modern style dining chairs usually use simple lines and Outlines, focusing on functionality and practicality, suitable for modern restaurants and cafes.
2. European classical style: European classical style dining chairs pay attention to gorgeous details and decoration, common hollow carving design and curve shape, suitable for high-end restaurants and banquet places.
3. Nordic style: Nordic style dining chairs focus on simple, natural and comfortable design, usually using wood materials and simple lines, suitable for family restaurants and cafes.
4. Industrial style: Industrial style dining chairs often use metal materials, with simple, solid and practical characteristics, simple and unadorned, suitable for cafes and bars and other places.
Second, according to the material classification
1. Wooden dining chair: Wooden dining chair is usually made of solid wood or artificial wood, with natural, environmental protection and warm characteristics, suitable for families and cafes and other places.
2. Metal dining chair: Metal dining chair is often made of metal materials such as iron, aluminum or stainless steel, with strong, durable and easy to clean characteristics, suitable for bars and cafes and other places.
3. Plastic dining chair: Plastic dining chair is usually made of polypropylene or polycarbonate and other plastic materials, with light, waterproof and easy to clean characteristics, suitable for fast food restaurants and school cafeterias and other places.
Third, according to the use of classification
Generally, it can be divided into two uses: domestic and commercial.
1. Home dining chair: Home dining chair pays attention to comfort and beauty, common dining table chair, folding chair and bar chair.
2. Commercial dining chairs: Commercial dining chairs pay attention to durability and practicality, common bar chairs, cafe chairs and fast food restaurant chairs.
In general: dining chair as one of the important furniture in restaurants, bars, cafes and other places, according to the design style, material and use of different, can be divided into a variety of categories. Choosing a dining chair that suits your place and needs can enhance the comfort and beauty of the dining environment.
