what is glass beads?

Glass beads as a low cost of particulate matter, is often used in mechanical descaling, urban traffic road zebra crossing, reflective and traffic signs forbid line night retroreflecting device. Its main chemical composition is sio2, from material to see this kind of material has the characteristics of high hardness, its appearance is bright and clean, roundness, some is transparent, round rate is as high as 85% above. The substance mixed in the plastic products to make plastic products with good toughness, but not their own hardness and lower. Glasss beads also has the characteristics of high melting point, can be applied in fire insulation engineering. High insulation properties can be used in high polymer insulation filling work. Glass beads of the density of 1.78 g/cm3, mixes with engineering plastics can obviously to achieve the effect of weight loss. Corrosion resistance is also a highlight the advantages of glass beads, some industrial plastic products will add some glass beads, corrosion resistance characteristics can be achieved. In short, the development of glass beads market prospect is very broad, temporarily not in the position in the market.
Due to the unique advantages of glass beads, glass beads are mainly used in the following aspects:
1, Road Marking Glass Microspheres
Main application interesting type and type hot melt road marking paint. Divide into two kinds, premixed and surface and premixed type glass beads can be in the production of hot melt type when the road coating mix in the paint, can ensure long-term reflective road marking in the life period. Another available in road marking construction over marking a instant reflection effect on the surface. After surface treatment of coated glass beads, used in road marking construction, and can greatly increase the glass beads with hot melt marking of adhesion, enhance road marking the refractive index, and have since used clean dirt, moisture resistance, etc. Road with glass beads coating resistance to improve pavement performance, improve the security of the driver at night.
2, glass beads in medical equipment and nylon, rubber, engineering plastics, aviation and so on various fields as a new kind of material has been widely used. Such as add agent, strengthening agent, etc.
3, arts and crafts glass bead, glass sand and colored glass beads, garment printing, garment pyrograph, surface decoration, artificial Christmas tree fruit, artificial flowers products surface decoration, the manufacture hourglass quicksand ideal!
4, used in industrial blasting and additive effect of the surface of the glass beads can be in metal and die surface, does not damage the workpiece surface, and improve the precision of the workpiece. Used for metal, plastic, metal jewelry, precision casting, such as cleaning and polishing of the object. Is widely used at home and abroad of high-grade finishing materials.
5, high refractive index glass beads is reflective fabric, reflective coatings, chemical coatings, advertising materials, clothing materials, reflective film, reflective fabric, reflective sign identification, airport runway, shoes and hats, bags, with both life-saving supplies, nocturnal staff wearing required materials and other products.
