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 ℃.

Hollow glass beads is a size small hollow glass spheres, is an inorganic non-metallic
materials. A typical particle size range 10-180 microns, a bulk density of 0.1 to
0.25 g / cc, a lightweight, low thermal conductivity, sound insulation, high dispersion,
electrical insulation and thermal stability, etc., is a development up to 2008 versatile,
high-performance new lightweight materials. Can be used in any color appearance of the
products required.
PWHGMs,developed in recent years,are a new type of materials which shows a greater use and an outstanding performance.The product,made mainly from borosilicate,is a hollow microsphere whose grain size is 10-250 micron and wall-thickness 1-2 micron. The products have many advantages:substantial weight saving,low heat conductivity,high mechanical strength and fine chemical stability.With treated specially,they have the properties of lipophilicity and hydrophobicity and are very easily dispersed in organic materials such as resin.PWHGMs are widely used in the composite materials such as FRP(fiber reinforced plastics),man-made marble and man-made agate.They have the distinct results of decreasing weight,sound insulation and heat preservation,thus the products have the excellent performances of anti-crazing and re-processing.They are widely to be used in a range of fields such as aviation,space,new bullet train,luxurious yacht,heat insulating dope,bowling balls and play a unique role.

Glass Beads of size 710 microns and below are being used as a reinforcement filler in the plastic industry. Depending on he job, bigger sizes are also being used. Spherical shape gives better stress patterns than the irregular shaped particles conventionally used. Glass beads are easily and uniformly dispersed throughout the plastic compound and produce smooth flowing compound which distributes itself evenly, so that all parts of any shaped moulding can be reinforced. Reinforcement with Glass beads will improve the tensile strength, reduce elongation, increase flexural modulus and in some plastics, triple the compressive strength of the finished product.
Given below are few examples of Glass beads being used in plastics :
In adhesives to increase the bond strength.
In fiberglass-epoxy laminates for improved flexural strength.
In moulded phenolic motor housings for good insulation.
In polyesters, using silver coated beads for moulding electrical conductors.

Hollow microsphere are light are light gray or off-white, light, inert and nonmetallic hollow ceramic spheres in the range from 10µm to 850µm.With N2 or CO2 inside and over 95% spheres, the material has excellent fluidity as well as sound electric and heat insulation, Hence it is called” The Space Era Material”. The hollow micro-spheres can be further divided into two kinds: Thin Wall Hollow Ceramic Micro-sphere and Thick Wall Hollow Ceramic Micro-sphere.
