Glass bubble,Hollow glass microspheres , Glass sphere beads, Manufacturer & suppliers

Additives, especially inorganic solid particulates, have greatly contributed to the growth of the polymer industry. They render polymers with improved mechanical, physical, electrical, thermal and dimensional properties, depending on their geometry and chemistry. Glass bubbles are finely dispersed, free-flowing powders consisting of thin-walled (0.5-1.5µm) spherical glass particles with an average diameter of 15-65µm.

Glass bubbles were developed in the 1960s as an outgrowth from the manufacture of solid glass beads. They are commercially manufactured by melting a unique glass formula that contains a latent blowing agent causing the molten glass particles to expand into a hollow bubble. The resultant glass bubbles are chemically stable, water resistant and compatible with many materials used for indirect food contact applications. The material technology has evolved in recent years to produce bubbles with a high strength to density ratio which enables their use in demanding polymer processing operations.

Hollow glass beads, high melting point, greatly improving the coating temperature resistance, play a good role in the fire, hollow glass beads bearing spherical particles play a role, friction is small, can enhance the flow properties of the coating film, so construction easier.

Suggested Use:
Generally added in an amount of 10% by weight of the whole surface-treated beads and low density, so that the paint during storage prone to viscosity increases and the floating phenomenon, we propose to increase the initial viscosity of the coating increases thickener (via the added amount of the viscosity control in 140KU above), and not because the viscosity is too low to generate the floating phenomenon, and each system in the particulate material in a decrease in activity due to the high viscosity of such a case, but is conducive to the stability of viscosity control.

Proposal to add the following methods:
In order to take full advantage of the characteristics of the hollow microspheres, recommended adding a last resort, that is added to the beads into the final as low speed mixing equipment dispersed using low shear force, because the spherical beads mobility well, between the friction is not large, so it is easy to disperse. You can complete a short wet, slightly extended mixing time to achieve uniform dispersion.

Beads chemically inert, non-toxic. However, because of a very light, so they need special attention added. Recommended stepwise addition method, which is the amount for each remaining 1/2 beads gradually added, this can be good to avoid beads float into the air and dispersed more complete.

Single From a cost perspective, if the hollow glass bubbles per unit mass of the same price, you should use the lowest possible density of hollow glass microspheres, so low unit cost.If just from a performance standpoint, because the larger the lower the density of the hollow glass microspheres diameter, large diameter also reduces the conductivity between the zinc coating, which reduces the resistance to salt spray paint, and therefore should be chosen particle size as small as hollow glass microspheres.There are on the one hand I must mention that, due to the formulation of other fillers such as zinc and iron phosphate high density, when the coating solution is stirred crashed hollow glass microspheres, and in the spray when a low intensity hollow glass microspheres are easily broken failure. Therefore, the density of the microspheres can not be selected too large, the particle size can not be too large, and the strength is sufficient.

Hollow glass microspheres in type Ⅱ Class 1 zinc coating for alternative discussion
In Class 1 zinc-rich epoxy primer, at least more than 80% of the zinc coating to be able to call a Class 1, and the current high zinc prices, affecting the profits of the product.Epoxy zinc-rich primer to sell if it is on the rise, the use of hollow glass microspheres to replace the zinc portion for savings is very significant cost savings, of course, can not be sacrificing too much performance and to meet the national standard.
With the same mass of hollow glass microspheres S38HS to replace zinc, zinc ensure the non-volatile component in the proportion is still more than 80%. Design 6 recipes, hollow glass microspheres proportion from 0 to 5%.
Recipe by salt spray resistance test 7 to 12 recipes can be found under the same conditions as the film thickness, with hollow glass microspheres increases, salt spray resistance coatings decreased, but can meet the national standard class Ⅱ type 1 the requirement that the resistance to salt spray for more than 500h. Reduce formulation costs but indeed very obvious.

Reduce shrinkage products and warped
Isotropic and high-performance glass beads filling volume characteristic hollow, so that the size of the very high stability of the products, can reduce shrinkage and warped. When filling the right proportion, toughness products improved significantly, significantly improved impact resistance, surface hardness increased.
The volume of more economical cost
High-performance hollow glass microspheres density is only a fraction of the resin density, only a small amount of hollow glass microspheres can replace heavier materials. When considering the cost per unit volume, rather than the cost per unit weight, high-performance hollow glass microspheres can significantly reduce costs.
Adjust product density
High-performance hollow glass microspheres density is usually in 0.2 ~ 0.6g / cm3, and the density of the mineral filler is generally about 2.7 ~ 4.4g / cm3. To get equal volume, you must use 14 kilograms or more talc to get a 1 kg hollow glass microspheres effect. So add different hollow glass microspheres can be an ideal density.

Hollow glass beads is a lightweight multi-purpose non-metallic materials, light weight, mild, good insulation properties and other unique features, it is the development of submarines and underwater robots and other submersible, strengthen national defense construction, deep-sea resource exploration and exploitation of new materials, known as “new space age materials.”

According to the target of Ti – HGM diameter and wall thickness for selecting the appropriate foaming agent content and particle size range with titanium dry gel particles, and then choose the appropriate carrier gas composition, temperature and pressure, the preparation for Ti – HGM; Finally using microscope and interference microscope distribution measurement of Ti – HGM diameter, wall thickness, and concentricity, sphericity microspheres are measured with X-ray spectral fluorometer titanium doping content in the spherical shell.

In recent years, the expansion of deep-sea in deep water exploration and production in the pipeline for controlling the flow of long-distance transmission and heat in seawater job loss has quickly become a major technology investments.Early, deep tunnels just painted some black paint, but the insulation performance is very limited.

Hollow glass microspheres in type Ⅱ class 3 epoxy zinc-rich primer for iron phosphate replace discussion
GB HG / T3668-2009 stipulates mass less than 60% zinc can not be called rich epoxy primer, primer in three categories zinc content can no longer little, hollow glass microspheres can only to replace the iron phosphate.
With the same mass of hollow glass microspheres S38HS to replace the anti-rust paint iron phosphate, zinc in non-volatile component to ensure the proportion is still 61%. Experimental Design 6 recipes, hollow glass microspheres proportion from 0 to 5%.
With the same mass of hollow glass microspheres S38HS to replace the anti-rust paint iron phosphate, zinc in non-volatile component to ensure the proportion is still 61%. Experimental Design 6 recipes, hollow glass microspheres proportion from 0 to 5%.Formulations 2 to 5 can meet the national standard recipe Ⅱ type epoxy zinc-rich primer Class 3 requirements, although at the expense of a little performance, but can reduce some costs. If you replace the ball with a hollow glass beads iron phosphate cost savings, go with the high price of zinc to replace the low price of iron phosphate, so that they can pay back part of the salt spray resistance.

For these reasons, hollow glass microspheres applications market is shrinking, this trend continues, we have reason to worry about the hollow glass microspheres thus eventually disappear from the market.On the contrary, the development of market Cenospheres more positive, the current domestic market a “prosperity”, coupled with the domestic thermal power plant transformation, yields drift beads have been great as before, floating bead supply shortage, the market purchase prices soared, but it is few people to care about foreign imports cenosphere is in what areas, and what is the result of deep processing, and then finished with what kind of price movement of domestic sales.

In such a big situation, Sinosteel Maanshan Institute of Mining Research Co. spent heavily to introduce high-performance hollow glass bead production lines once the market, with its high compressive strength, low oil absorption and low thermal conductivity and a reasonable sale price is widespread concern, and gradually occupied the hollow glass microspheres vacuum market.Our hospital with hollow glass microspheres to market in a responsible manner the situation and re-regulate its market position and through practical work hard and continue to strengthen the production, use of technology, resources, markets and group advantage, set up factories in Ma On Shan, efforts let the steel horse mine hospital beads became a core technology, China’s leading, world-class manufacturing enterprise hollow glass beads, hollow glass microsphere product reunification standards.Application of hollow glass beads beads market has basically been excavated, mainly used in: thermal insulation coatings, anti-corrosion coatings, heat resistant coatings, powder coatings, fire retardant paint, plastic modified materials, filled with ordinary plastics, glass and steel products rubber products, oil and unsaturated resin filler (glass fiber reinforced plastic). Market feedback is good, even for some time shortage phenomenon, this phenomenon is not accidental, but inevitable trend of the market.

1, to improve the flow properties
High-performance hollow glass beads are tiny spheres, ball rate, with a ball bearing effect, can improve mobility, can reduce the viscosity and the internal stress of the resin mixture. Therefore, in the process of composite materials dynamically generated less heat, lack of lubrication and to prevent local thermal decomposition, easier extrusion injection, not only to reduce defects in products, and the production efficiency increased by 15 to 20%.
2, the higher resin replacement rate
High-performance hollow glass microspheres having a minimum surface area and low oil absorption rate, which in the mixture can have good dispersion, can easily be compacted and fused, so it has a very high filling performance, can greatly reduce the use of resin traffic, increasing the amount of filler, effectively reducing the VOC indexes, while reducing costs.

Since the foam glass just changed the physical shape of the glass material, raw material reserves the chemical structure of glass and excellent physical properties, and therefore it is used to be used as wall insulation materials, has many advantages, such as the ability of a variety of chemical corrosion, acid rain can improve thermal insulation system, mist, atmospheric carbonation, anti-erosion water softening, UV aging and other natural weathering performance.Foam glass does not absorb water, both high temperature and low temperature resistant, suitable for the safe use over a wide temperature range of -196 ~ 400 ℃ above zero, which is resistant to high temperatures and frost magic. Meanwhile, the quasi-closed cell foam stained glass does not absorb moisture, does not adsorb moisture, so the rain will not long remain in the body and damage the insulation bricks, help improve water resistance, frost resistance of external thermal insulation systems.Reduced thermal expansion coefficient of insulating foam glass and building brick, concrete, mortar and other infrastructure materials similar wall, so as long as proper selection of adhesive material, foam glass wall insulation to maintain synchronization with the Wall base expansion and contraction can improve interlayer combination of robustness and reliability, and help to improve the durability of exterior insulation systems.In addition, insulating foam glass non-absorbent, moisture, rain does not stay, it will not be due to water absorption and thermal conductivity significantly increased, enabling external wall insulation system to maintain a stable thermal insulation effect, but do not burn foam glass, non-toxic, safe reliable, very much in line with environmental requirements on domestic and international.
