Hollow glass beads spherical structure makes the impact force and stress have a good dispersion, added to the paint can well improve the resistance to external impact properties of the film, and the coating can be reduced due to thermal expansion and contraction the stress cracking.

Filling the hollow glass microspheres can effectively reduce other expensive fillers and pigments dosage (compare with titanium dioxide, but its volume costs beads 1/5) effectively enhance the adhesion of the coating. Low oil absorption properties of glass beads so that more resin can participate in film formation, so that the adhesion of the coating increased 3 to 4 times.

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.

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.

Filling the hollow glass microspheres can effectively reduce other expensive fillers and pigments dosage (compare with titanium dioxide, but its volume costs beads 1/5) effectively enhance the adhesion of the coating. Low oil absorption properties of glass beads so that more resin can participate in film formation, so that the adhesion of the coating increased 3 to 4 times.
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.

Foam glass in its inorganic silicate material and separate collection of tiny pores closed tight, non-burning, anti-gnawing decay, acid and alkali, non-toxic, radioactive material, chemical stability, ease of processing and non-deformation characteristics, life equal to the life of the building, is a safe, reliable and durable building energy-saving materials.
Applications: foam glass can be used in civil construction walls and roof insulation. Since the foam glass light, fire, water, pollution-free, non-burning, long life and other advantages, coupled with human survival increasingly demanding environmental protection, foam glass wall so that senior civil ideal insulation and roofing insulation.
Foam glass is both a cold material and insulation material, able to adapt to the higher cryogenic temperature range of features. At the same time it is important not only that the perennial value will not deteriorate, and itself plays fire, earthquake effect. In cryogenic, underground engineering, explosive, humid and chemically aggressive harsh environments, the only safe, reliable, and durable, known as the “no need to replace a permanent insulation materials.” It is widely used in petroleum, chemical, engineering, shipbuilding, defense industry thermal insulation cold and flue liners preservation projects.

Light weight; bulky
Hollow glass microspheres density of about one dozen points of traditional filler particle density, after filling can greatly reduce the weight of the base product, alternative and save more resin production, reduce product cost.

Has organically modified (lipophilic) surface
Hollow glass beads wetting and dispersing readily be filled in the most thermosetting thermoplastic resin, such as polyester, epoxy, polyurethane and the like.

High dispersion, mobility
Since china glass microsphere are tiny balls, the liquid resin than the sheet-like, acicular or irregular-shaped filler even with good fluidity, so that excellent filling performance. More importantly, such a small bead is isotropic, it does not produce a result-oriented in different parts of the shrinkage caused by inconsistent ills, ensure that the product is dimensionally stable and will not warp.

Insulation, sound insulation, insulation, low water absorption
Internal hollow glass microspheres is rarefied gas, so it has the characteristics of noise, heat, and is used as a variety of insulation, excellent sound insulation filler products. Thermal insulation properties of hollow glass microspheres can be used to protect the product is subjected to alternating between heat and quench emergency conditions caused by thermal shock. Higher specific resistance, low water absorption so that it can be widely used in processing the cable insulation.

Low oil absorption
Spherical particles determines the minimum specific surface area and low oil absorption, use of the process can significantly reduce the amount of resin, even under the premise of a high added amount of the viscosity is not increased much, greatly improved the production operating conditions, production efficiency increased by 10% to 20%.

China glass microsphere, has been around for ten years or so, but it really is industrial production and the use of only a short five or six years or so, but on their current market situation, the global situation at large, there the substantial needs, including with the insulation materials, coatings and various other high-end military and civilian products.

Cenospheres products are divided into three categories: white hollow glass beads; one is floating beads; there is a class resin beads. Each category is divided into a variety of specifications of products, used in different fields. In terms of market applications cenospheres product point of view, now more mature customer base should be foreign, domestic large enterprises started relatively late, the vast majority have not come into contact with such products.But also the most important point, foreign companies and Porter company 3M hollow glass beads, due to price and delivery time, most domestic customers which can only wait and see situation, some of this is already in use users of the product are also trying to find 3M and Potter’s beads alternatives.Domestic producers of beads confined to limit the production technology and equipment, has been unable to provide a high-performance alternative to the market vacuum, some companies began to fish in a very poor product and low market price to disrupt the market. Judging hollow glass beads application situation continues to forge ahead, in fact, exactly the opposite, due to defects in each of their own technology, making cenospheres product quality is uneven, with greatly reduced the quality of their products, but affected the hollow glass microspheres Pearl market expansion.

Investigation of hollow glass microspheres (HGB) type and amount, type and amount of silane coupling agent and other effects of hollow glass microspheres / low-density polyethylene (LDPE) density and mechanical properties of composite materials. The results showed that: 20 parts of glass beads is more appropriate dosage; coupling agent A-172 glass beads treatment is better than KH550; when the A-172 dosage of 1.0% optimum mechanical properties of composite materials, including impact strength than before treatment increased by 24%, the tensile strength than before treatment increased by 18%; scanning electron microscopy (SEM) showed significant improvement in A-172 glass beads combined with LDPE interface. Hollow glass beads for weight loss is not as LDPE LDPE chemical foaming obvious, but it can better take into account the “light” and mechanical performance requirements.

In the automotive industry, construction industry and other applications, often need to avoid a significant reduction in the mechanical properties of plastics on the basis of the original as much as possible to reduce weight and reduce costs. Effective method of reducing the density foamed plastics modification, adding lightweight fillers. The use of azo dimethylamine (AC) chemical blowing agents for foamed plastics modification, can significantly reduce the density of the material, but there are difficult to accurately control the degree of foaming, nonuniform cell structure and other drawbacks, resulting mechanical properties (tensile strength, modulus, etc.) deteriorate.By adding a lightweight filler material way to reduce the weight of these problems can be avoided. Typical lightweight filler is hollow glass beads. This is a powdered inorganic filler, can be taken directly from the glass system, it can also be isolated from coal ash. Its microscopic structure wrapped with a certain amount of gas in the thin-walled, closed microspheres, the relative density is generally 0.4 to 0.7, lower than usual relative density of plastics. Hollow glass microspheres have a smooth spherical surface, it can reduce the weight of the material at the same time, improve mobility and surface quality composites. Hollow glass beads also has a low thermal conductivity, heat resistance, corrosion resistance, and controllable size advantage.

There are many preparation methods of hollow glass microspheres, such as flame, into the ball inside the furnace, Si – GDP (silicon doping glow discharge polymerization coating) spherical shells pyrolysis and sputtering method, etc. In many ways, furnace into a ball of mature technology, prepared by the quality of microspheres (concentricity, sphericity and wall thickness uniformity, etc.) is higher, and is suitable for batch production, hydrogen storage with hollow glass microsphere preparation is one of the main candidate method.Furnace into a ball method according to different raw material state can be divided into droplets method and dry gel method. Ball temperature range of the main equipment is more SPC vertical high temperature furnace, droplet method and the solution of sodium silicate on raw materials, raw materials by droplet generator change uniform droplets into the high temperature furnace, and raw materials for high gel method of dry gel particles. Using the furnace into the ball technology preparation of glass microspheres in 150 ~ 250 microns in diameter, wall thickness in 0.9 ~ 40. Mu m between. The diameter of the microspheres and the wall thickness can be adjusted by using condition.

Optical glass beads, as a new product in the glass industry. It has a certain chemical stability, mechanical strength, electrical insulation and be rounded, uniform, and good liquidity.Its most unique properties with the original glass transparency, with the return of retroreflective performance. Especially the use of different conventional glass raw material of high refractive index glass beads much broader range of applications than the ordinary type beads, in addition to serving highways and airports and all kinds of road marking paint sign board outside,Can also be made reflective clothing, reflective rain gear, a traffic policeman on duty at night with reflective sleeves, etc. It can greatly reduce traffic accidents at night or in rain and fog days. Early in the 1960s the US government to develop a “federal highway regulations” provides highway lane, traffic signs, road signs, road signs and so on.In the headlights illuminated necessary to achieve the standard luminous indicators improve visibility distance traffic signs, the need to adapt to the highway. That this is to reduce traffic accidents most cost-effective way.”International maritime rescue organization” has also been stipulated that all vessels with a life buoy, life jackets and all life-saving equipment and the corresponding buoy flags are required glyphs reflective material with a high refractive index glass beads made.Helicopters and lifeboats to sea only available light to detect targets at night and rain and fog days in the rescue time and space. So that in addition, the use of high refractive index glass microspheres made of other reflective materials are also widely used in other industries, for example: large oil derrick, tower, movie screen, large public spaces such as billboards.
