In recent years, the demand for sealant in the construction field has been increasing, among which the silicone sealant is widely used and has a large amount. The silicone sealant is prepared with polysiloxane as the main raw material, and its molecular chain is composed of siloxane chain, which is cross-linked to form a network of siloxane chain skeleton structure during the curing process. The bond energy of Si-0 (444 kJ/mol) is very high, which is not only much higher than the main chain bond energy of other ordinary polymers, but also higher than the UV light energy (399 kJ/mol). Therefore, Si-0 has excellent high and low temperature resistance, weather resistance and UV light aging resistance.

In addition, silicone sealant is also a good adhesive material. Its adhesive performance to glass is very excellent, and it is often used for sealing and bonding of double-layer insulating glass. Reinforcing filler accounts for a relatively high proportion in the formula of silicone sealant, and the commonly used ones include Nanomaterial calcium carbonate, fumed silica, carbon ink, etc. When the nanomaterial calcium carbonate is used as reinforcing filler, the dosage can reach 60% of the total mass of the system. In addition, some silicone sealants will also add incremental fillers to reduce costs, adjust and improve thixotropy and fluidity. The commonly used incremental fillers are heavy calcium carbonate. The common feature of the above fillers is that the density is high, such as the density of Nanomaterial calcium carbonate is 2.7g/cm3, which also leads to the high density of the final product sealant, and the density of most silicone sealant is about 1.5g/cm3. Hollow glass microsphere, also known as hollow glass microsphere, is a lightweight inorganic powder material developed in recent years.

Hollow glass beads are borosilicate glass formed at high temperature (>1400 ℃) and have stable chemical properties. The hollow glass bead is a hollow, thin-walled closed spherical structure with thin gas inside. This special structure makes it have the characteristics of low density, low thermal conductivity and high compressive strength. The true density of hollow glass bead is 0.12-0.70g/cm3, and the thermal conductivity is 0.038-0.085 W/(m · K). It can be used as a semi-reinforcing filler in silicone sealant, effectively reducing the density and thermal conductivity of the sealant, and also improving the thermal deformation temperature of the sealant. In addition, hollow glass beads generally do not react with substrates or other substances, and are suitable for a variety of systems.

Reflective glass beads are widely used in reflective materials such as reflective cloth, reflective coating, reflective webbing, screen printing, reflective hot-melt film, reflective leather, reflective wire, reflective ink, reflective paint high-strength reflective film, etc.

How to Reduce Density of Rubber Vacuum Glass Bead Foaming Agent Special for Rubber Weight Reduction

Why rubber has high density;

The density of the rubber without filler is 0.9g/cm, but the rubber needs to add inorganic filler because of its strength, temperature resistance, shrinkage resistance, cost reduction and other characteristics. The filler density is generally 2.5-3.6, which will greatly increase the weight, leading to the rubber density exceeding the standard.

Inorganic filler powder

Methods for reducing the density of rubber;

The vacuum glass beads are added to the rubber. The density of the vacuum glass beads is 0.23-0.28g/cm, 3-5 times lighter than the rubber. The compressive strength is 35-42MPA. It has high strength and does not crush. It can be filled into rubber and other materials to effectively reduce the weight to meet the density standard.

Vacuum glass beads are often used to replace foaming agents in rubber soles. Because of their high strength, strong weather resistance, high hardness, and strong aging resistance, vacuum glass beads will not collapse for a long time after they are made into soles, delaying their service life.

Glass used to be called colored glass because of its twists and turns. When the light passes through the glass, the refracted light is very beautiful. We all know a little about the use of glass, such as cups, windows, decorations, etc. Because of the strong plasticity of glass, it can be made as it is.

Do you know about glass beads? This is a new material that has been developed slowly in recent years. Please see below for the specific use of glass beads.

Use of glass beads:

1、 There are three types of reflective glass beads for roads:

1. It is used for surface spreading during normal temperature and hot melt standard construction, which has a strong reflective effect!

2. As a premixed material, it is premixed in the coating during the production of hot-melt road coating, which can ensure that the marking will reflect light for a long time within its service life

3. This kind of glass bead should be used to sprinkle glass bead on the surface of normal temperature solvent paint marking.

2、 Glass beads for industrial use

1. Purpose

(1) It can be polished on the surface of metal and mould, and can be used as metal abrasive material, which will not damage the working surface and improve the precision of the workpiece.

(2) It can be used for military cleaning and sandblasting, and is used for cleaning turbine, blade, shaft, etc. of aircraft engine.

(3) In the chemical industry, glass beads can be used as additives and reinforcers in the production of plastic, rubber, paint, nylon and other adhesives.

2. Principle

During polishing, compressed air is used as the injection power, glass beads are used as the medium, and the workpiece surface is sprayed at high speed and high pressure for shot peening strengthening and polishing

The processing achieves the purpose of cleaning and improving the processing precision.

3. Advantages

(1) The glass beads made of soda lime glass have good chemical stability, certain mechanical strength and hardness. Therefore, they have great advantages as polishing and grinding materials compared with other grinding materials.

(2) It will not contaminate the processed metal.

(3) It can speed up the cleaning and restore the original cleanliness and finish of the processing materials.

3、 Other applications

1. Glass beads have been widely used in artificial agate, marble, glass fiber reinforced plastic bowling ball and other composite materials as well as high-grade thermal insulation coatings, which can significantly reduce the weight of products and have good thermal insulation effect.

2. Glass bead is a sensitizer with excellent performance for civil emulsion explosives, which can significantly improve the initiation performance of emulsion explosives and extend the storage period. In addition, hollow glass beads can also be used to increase the volume of putty, improve the grinding performance, and improve the acid and alkali resistance.

It can be seen from the above that the use of glass beads is very extensive. Glass beads are a new type of material. With its slow development, it is believed that glass beads will have more and more uses and will be used in more industries. This is to be explored slowly. And glass beads are also used in zebra crossings on urban traffic roads. Under the sun or light, there will be some light flashing to remind everyone to be careful. As for the future use of glass beads, let’s wait quietly.
