Someone is moving its glass microspheres into greenhouse films for the agricultural market.

Using microspheres can allow producers to make more amounts of low density and linear low density film with the same amount of resin, application development engineer Fernando Cervantes said at Plastimagen 2016 in Mexico City.

Microspheres also can provide whiteness to films, allowing for the replacement of titanium dioxide, he added. The materials also can spread light over a greater area, which helps plant growth.

Development of microsphere films began last year in the U.S. St, Paul, Minn.-based they now is working with film producers on the new application.

In Mexico, they have operated an innovation center in San Luis Potosi since 2013. Overall, they have done business in Mexico since 1947 and employs a total of 7,000 there.

They microspheres were used in body panels that were honored in November by the Society of Plastics Engineers’ automotive division. The award went to General Motors Co. for body panels made using composite material from Continental Structural Plastics. Auburn Hills, Mich.-based CSP replaced calcium carbonate with hollow glass microspheres and a proprietary surface treatment to achieve mass reduction of at least 28 percent vs. standard materials.

In 2015, they posted sales of just over $30 billion. Its products include adhesives, abrasives and specialty materials.

We can not only produce common glass beads, but also developed coating technology. The coated glass bead is a new product of glass beads developed in recent years,which is used for road graticule surface spreading. With the excellent charcteristics,the great majority of users have paid more attention to it .
The coated glass bead have been treated with high quality organic materials on their surface, thus bearing better features in quality. Our company has developed this unique product after absorbing advanced technology from foreign countries and it has the following advantageous features:
Glass beads surface coating is not easy to be eroded. In the process of storage and usage, glass beads whose surface is easy to be moisture is in humid atmosphere, It leads to light scattering,and therefore influences the direct reflection.
Glass beads coated material is a kind of organic material which may have better consolute with road coating material. While being spread on the road graticule surface,it is not easy to come off, It has stronger adhesion force specially used on coating material graticule of constant temperature (including water soluble coating material)and may maintain light reflection effects for a long time.
Coated glass beads has better adhesiveness with road coating material,particle sedimentation can be controlled after surfacer spreading through reasonable galss beads particle grading so as to ensure better reflection effect of the graticule.
Coated glass beads has good fluidity,with the characteristic of non-blocking. mean spreading,easy construction and good reflection effect.It is proved practically that it can save about 15%usage amount.

Improve flow properties

Hollow glass microsphere is a tiny sphere with high ball-type rate. Its ball-bearing effect can improve its mobility and reduce the viscosity and internal stress of resin mixture. Therefore, during processing, less heat is produced in composite materials so as to prevent inadequate lubrication and partial thermal decomposition. It is more likely to extrude when molding, which can not only reduce defects in products, but also improve the production efficiency by 15% -20%.

A superior substitute of resin

Hollow glass microspheres occupy less surface area, low oil-absorption rate, and evenly disperse in mixture. Its easy compression and integration permit high filler loadings. It significantly reduces the consumption of resins, increases the amount of filler, and effectively reduces VOC indicators, and costs as well.

Low shrinkage and warpage

Hollow glass microspheres have the feature of isotropism and high-filling, hence the dimensional stability of the product will be very high and it will reduce the shrinkage and warpage. With an appropriate filling ratio, the toughness of the products, impact-resistance and surface hardness can be significantly improved.

More economical

The density of high performance hollow glass microspheres is only a fraction of that of the resin. A small amount of hollow glass microspheres will be able to replace heavier materials. When considering the cost per unit volume, rather than cost per unit weight, high-performance hollow glass microspheres can significantly reduce costs.

Adjusting product density

The density of hollow glass microspheres is usually 0.20 ~ 0.60g/cm3, and the density of mineral filler is generally around 2.7 ~ 4.4 g/cm3 (The data adopted is the true particle density). In order to obtain the equal size, 14 kilograms or more of talc must be used to obtain the same effect of 1 kg of hollow glass microsphere. Hence the desired ideal density can be obtained by adding appropriate proportions of hollow glass microspheres.

Glass beads are fired through the glass sand. Glass beads can be divided according to the size of the glass bubble (glass bubble is a glass bead, referring to a particle size of 1mm or less solid sphere) and glass beads. By applications can be divided into reflective glass beads, sand blasting with glass beads, glass polishing beads, filled with glass beads. Reflective glass beads which can be divided into safety classes reflective glass beads and silver screen with glass beads; by the refractive index to points, can be divided into ordinary refractive index and high refractive index glass beads. Usually a refractive index of between 1.5-1.64, a high refractive index is generally 1.8-2.2. If, as is most appropriate to use reflective glass beads refractive index of 1.93, the refractive index can be perfectly parallel rays refracted back, so it is not the best reflection refractive index higher. According to the shape of points can be divided into rules and irregular glass beads glass beads. Divided by color can be divided into a colorless, transparent colored glass beads and glass beads.

Endothermic temperature drops, the water acts as a foaming agent to the surface of the glass powder agglomeration, concentrated sodium silicate to the surface, forming shell beads from glass powder and water glass preform formed. Semi-finished beads tower sintering furnace, after melt, foam and annealing process is finished baking beads.

Glass bubble flotation method commonly used flame, release agent production method and the injection method. Where the blowing method is a molding method, generally using mineral raw materials for production. Flame floating method and release agent law is secondary molding method, usually recycled glass as raw materials to produce, more common in domestic applications.
The basic principle of flame float method is that the recycled glass is crushed into particles of a certain size, and in such a way the glass particles into a flame, under the action of the flame, glass particles softened, melted, beads oriented, cooled and solidified i.e. become a glass bubble.

Road with reflective glass bubble, mainly used in normal temperature type, hot melt road marking paint, a material as a premixed, marking ensures long lifetime in the reflection; a surface-spreading when marking construction can instant play reflective effect.
Coated glass bubble is divided into two, one as reflective highway, another as a screen with reflections. Coated glass bubble is the use of a high performance organic material on glass bubble were outside treatment, making glass bubble surface adsorption of dust in the air blunts. Since the coated beads containing a specific coupling agent, to improve the adhesion of the coating bead and prevent some small glass bubble deposited coating. Because of its functions can be floating, floating on the surface of the coating when used, it has the largest surface area can be increased by more than 30% utilization. Glass bubble superior performance after coating treatment. Rain is often foggy in a humid environment, with better reflection function.

Hollow Glass Microspheres itself is inert without pollution. As a continuous medium, low density drilling fluid with addition of hollow glass microspheres was incompressible, and all wells are uniform in density. Sludge cakes formed have good lubrication, reducing the risk of sticking. It is technically infeasible for drilling large deviated wells and horizontal wells since the recycled micro-foam and air drilling technology can not deliver MWD signal. However, hollow glass microspheres have an irreplaceable advantage for it can not affect the system signal.
