Product Description

High performance Hollow glass microspheres for Lightening agent


Description of hollow glass microspheres:


High-performance hollow glass beads are a kind of ultra-lightweight inorganic non-metallic materials in the form of hollow micron-sized spherical powders. Because of their excellent performance, they are known as "composite materials", "space materials in the new era", and "magic powder". It is a new type of functional industrial filler with many unique characteristics such as light weight, high strength, heat insulation, good fluidity, and corrosion resistance.
It is a special material necessary for the manufacture of large aircraft and other aerospace vehicles. It is a general basic material in the marine field.

Properties of hollow glass microspheres:



1. Good economy


Compared with fillers of other shapes, hollow glass beads have a small surface area to volume ratio and low oil absorption, which can reduce the amount of matrix resin and increase the amount of fillers. At the same time, glass beads with a smaller volume can be filled into larger gaps of glass beads, increasing the total filling amount, further reducing the amount of resin, and reducing the cost. Lightweight glass hollow microspheres can occupy more volume than ordinary fillers of the same weight. This means that hollow glass microspheres have more cost advantages when considering unit volume cost rather than unit weight cost.


2. Reduce viscosity and increase fluidity


The appearance of hollow glass microspheres is spherical. Compared with other irregular-shaped fillers, it is easier to flow and can roll like steel balls in a bearing. Therefore, adding hollow glass microspheres to the composite material can reduce the melt viscosity and The internal stress makes the processing and forming easier, which is conducive to the conventional forming of composite materials.


3. Reduce material density


Generally, fillers have a relatively high density and are added to plastics and rubbers as extenders. Although they can achieve the purpose of reducing costs, they tend to increase the density of the products and affect the performance and use of the products. Because hollow glass beads are hollow products, especially floating beads, the density is very small, about 0.40 ~ 0.75 g/cm3. Now some products, such as some hollow glass beads of 3M company, have a lower density, which can reach 0.125~0.16. g/cm3 level. Adding such low-density fillers to plastics can not only reduce costs, but also make products lighter.



Application of hollow glass microspheres



0.2-0.6 G/Cm3 Hollow Glass Microspheres For Lightening Agent 0


1. Hollow glass microsphere for lightweight heat-insulating refractory brick


This product is made of hollow glass beads, clay and other materials through high-temperature sintering. It has light heat insulation performance, especially its thermal conductivity increasing gradient ratio is smaller than any other materials as the temperature rises. It is a good heat insulation refractory material.


2. Hollowglass microspheres for reflective thermal insulation coating


Taking advantage of the suffocation and high temperature resistance of the gas in the hollow cavity of the hollow microspheres, it is used as a heat-insulating refractory material, using synthetic inorganic binders as the base material, using a composite flame retardant, which can be adjusted into different colors, with room temperature curing and coating Thin layer, non-toxic, non-combustible, convenient construction, wide source of raw materials, simple production process, low cost, etc., can be widely used in cables, underground engineering, industrial and civil buildings and other fields.


3. Hollow glass microspheres is used as fillers for plastic rubber


The use of hollow microbeads to highly fill PVC plastic flooring was successfully developed as early as 1984. It can improve and give products some special functions, so that the product has the advantages of dimensional stability, flexibility and elasticity. At the same time, because the hollow glass microspheres are smooth spheres, thin, uniform, isotropic, and dispersible, they can significantly increase the filling volume, save resin, and reduce shrinkage, which overcomes the shortcomings of general calcium plastic floors that are easy to bulge and deform.

Using hollow glass beads instead of calcium carbonate as the filler of rubber products can improve the properties of rubber products such as tensile strength, tearing strength, ductility, and good hardness, and is beneficial to lightweight rubber products and lower costs.


4. Hollow glass microspheres for buoyancy material


In marine development, a large number of very good buoyancy materials are needed, and composite buoyancy materials can be produced using hollow glass beads as the main raw material. Its outstanding features are low density, good thermal insulation, strong weather resistance, good electrical insulation, high strength, can withstand high hydrostatic pressure, are not easy to cause destructive damage, and have low water absorption during use. At present, this buoyancy material has been used as a domestic lifeboat material, and provides good materials for the development of my country's seabed mineral deposits and the construction of ships and offshore factories in the future.


5. Oil exploration cementing mud and drilling fluid


High-performance hollow glass beads, the highest strength can reach 18000psi, is a new type of low-density high-strength cementing lightening material, can be used for the preparation of low-density cement slurry in oil fields. The high-performance hollow glass microspheres are made of soda lime borosilicate ultra-light materials. They are rigid spheres and will not deform when heated. The cementing ultra-low-density cement slurry prepared by the lightening agent has good fluidity, viscosity, low water loss, and significantly improves the compressive and flexural properties of the cement stone after solidification, and also improves In order to improve the thermal stability and durability of cement stone, the density of cement slurry made by mixing with cement is 0.90~1.45g/cm3. The cementing quality is better than fly ash hollow float beads.
