Reflective powder is the high refractive index glass microsphere hemisphere aluminum, provides self-reflection layer, and less to others such as aluminum paste base, so that the beads have a self-reflective function, reflective way more effective than a bottom aluminum paddle method 4-5 times, widely used in reflective paint, reflective ink and screen printing.
High refractive glass microsphere having predominantly retroreflective properties. The so-called return reflection is an optical phenomenon, when the light shines on an object like a lens, focusing refracted, and then they return light refracted through the lens focus from reflection direction.After the products using high refractive index glass beads and a half after the surface of aluminum as the reflector, with a strong reverse retro-reflective properties, making 85% of the light directly reflected back toward the source.Reflective retroreflective brightness caused by the driver and the night allows workers with a light source in case of poor vision at night or circumstances clearly see pedestrians and obstacles to the goal, to ensure that both safety.
Sinosteel Maanshan Mining Institute New Material Technology Co., Ltd. is specialized in the research and development of high-performance hollow glass microspheres, sales of integrated high-tech enterprise under Sinosteel Maanshan Institute of Mining Research Limited. 2009 new materials technology company developing high-performance hollow glass microspheres products have comprehensive on the market.
To speed up the application of glass beads in the domestic market, and help domestic enterprises to improve product performance, the mine hospital related domestic industries and enterprises to actively carry out cooperation.
Province, a paint factory is a well-known hospital with the help of the mine under the successful development of a new thermal insulation coatings, this product has been successfully applied for the high-tech patent products, effective solution to the traditional building energy-saving insulation of high production costs, easy wall seepage, flammability and other issues, and to promote new products in Anhui Province certificate, companies are thus in one fell swoop into the high-end paint market.
Hollow glass beads is a small density, glass microspheres lightweight, high strength. The main ingredient is Sio2 and Al2o3, because of its unique chemical properties, physical properties, and hollow spherical, compared with ordinary glass beads, light weight, low density, good heat insulation performance characteristics, is thermal insulation coatings the main raw material. Because of its smaller particle size, equal to or greater than the ordinary paint fineness of the filler, which can be added directly to the filler coating systems, the coating having a cured coating film formed by thermal insulation properties.
Hollow glass beads grout
Hollow glass beads slurry mainly cement, hollow glass microspheres, reinforcing and supporting the additive composition, according to cementing needs, choose a different additive system, the design of different density slurry formulations.
In addition to the strength of the grout and cement and cement formulations label the outside, depending on the size of the water-cement ratio of cement. Select the appropriate water-cement ratio, it can be grout with good flow properties, while other properties are easy to adjust. Whether water-cement ratio is too large or too small, for slurry properties are unfavorable. Too large, floating glass beads, Strength grout; too small, poor water slurry rheological properties, not easy to pumping operations.
Hollow glass beads formulated low-density slurry, poured into the conservation atmospheric consistometer 20min at 45 ℃ condition, and then six-speed rotational viscometer rheological properties, it can be seen, hollow glass beads grout good rheological properties, rheology power-law model in line, show the grout can form a stable royal space structure, to ensure the stability of slurry.
Hollow glass beads low density, high compressive strength, good compatibility with cement additive performance, which can effectively reduce the slurry density; hollow glass slurry system performance and stability, good rheological properties meet the coalbed methane wells cementing security; hollow glass beads slurry filtration system is small, coal-bed methane wells can play a good protection.
Hollow glass microspheres in the application of the cementing cement
Pure cement generally be used on most traditional drilling, but in exceptional circumstances regulate cement density is the key to successful completion and long-term isolation.
There are several methods of adjusting the slurry density has been used. These methods can be used alone or integrated use.
One of the major advances has been the use of high reflectivity hollow glass beads for the preparation of new thermal insulation coatings. The results showed that the order of influence of pigments and fillers on the reflectivity of the coatings was: hollow microspheres> titanium dioxide> sepiolite> aluminum silicate, while the emulsion species had little effect on the reflectance of the coatings; and when the addition of hollow glass beads , The reflectivity of the coating also increases, in the hollow glass beads content of 35%, the thermal insulation coating thermal reflectance to achieve maximum. While the use of hollow glass beads and high refractive index of the white pigment can effectively improve the insulation effect of paint. In the traditional water-based paint formulations on the basis of adding high-reflectivity hollow glass beads and ultra-fine titanium dioxide composite composite pigment filler and infrared radiation-type composite function filler, can be prepared with high reflectivity and high radiation-based, supplemented by traditional insulation Of the new water-based insulation coating. Recent studies have shown that functional materials, different blending methods and different proportions, for the thermal insulation coating has a great impact. Infrared powder heat absorption of the building has a certain emission function, can speed up the indoor cooling rate, is a new type of active cooling insulation coating. In addition, the base material with pure acrylic emulsion, pigments and fillers with high refractive index of rutile titanium dioxide and hollow glass microspheres prepared by the insulation coating, the reflective effect of insulation with the insulation filler content increased, When the content of hot filler reaches 13%, the effect of reflection heat insulation reaches the maximum. It was also reported that the use of xonotlite as barrier filler to rutile titanium dioxide and hollow glass beads for the functional filler can be prepared an excellent building exterior insulation coating. The results show that the addition of xonotlite, rutile titanium dioxide and hollow glass microspheres can improve the thermal insulation performance of the coating. The composite materials can further improve the thermal insulation performance. When the above functional fillers The reflectance of the coatings can reach 93.69% when the content is 9%, 30% and 15% respectively. Coating for the wavelength of 250 ~ 2500nm in the range of the maximum reflectivity of sunlight, the insulation temperature difference of up to 13 ℃.
