There filling performance energy efficient, low low oil, density, added 5% (wt) will be able to make the finished product increased by 25% to 35%, so as not to increase or even reduce the cost per unit volume of the coating. Hollow glass beads particles confined hollow spheres added to the coating formation of many independent microscopic cavity insulation, thus greatly improving the coating on the thermal and sound insulation, play a very good thermal insulation and noise reduction effect. The coating has a more waterproof, anti-fouling, corrosion resistance. When the surface of the hollow glass microspheres are chemically inert chemical resistance, as the film tightly packed particles of glass beads, the formation of low porosity, the coating formed on the surface of the moisture and corrosion caused by the blocking effect of ions protective film, played well protective effect.

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.

Improving 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%.

More substitute ability for 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 by volume.

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 the density of products .

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.

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.
