1、 Introduction of new perlite floating beads

This product is a kind of tiny, round and hollow spherical powder material formed by selected special perlite ore under high temperature above 1000 ℃ after complex chemical and physical changes. It is a good substitute for the functional materials separated and purified from fly ash and the decreasing floating beads in power plants.


2、 Main characteristics of new pearlite floating beads

The results are as follows: 

1. The new perlite floating beads can improve the rheological property, reduce the viscosity, and reduce the weight of the product, especially the specific gravity of 0.3-0.4g/cm3 can greatly reduce the weight and cost of the product, which is a new functional filling material for unsaturated resin;

2. High filling performance, low binder content and small specific surface area, so the binder is less than the general filler;

3. Chemical stability, aluminum silicate material has strong chemical stability;

4. The melting point of fire resistance is more than 1000 degrees, which can be used as a good aggregate for fire retardant coating, especially for intumescent fire retardant coating;

5. Heat insulation and sound insulation, thin-walled closed hollow sphere structure, so that it has a unique heat insulation, heat insulation, sound insulation and other effects, widely used in heat insulation, heat insulation, sound insulation coatings and other products.


3、 Application fields of new pearlite floating beads

1. New perlite floating beads are used as fillers in the plastic industry. Wood plastic products (wood substitute, imitation) have the advantages of large consumption, low cost, high strength, good heat resistance and low thermal conductivity;

2. Make good light refractories with high strength, long service life and low thermal conductivity at high temperature;

3. Making high efficient thermal insulation material with low price;

4. Make waterproof coating with good function;

5. It can play a good plugging effect in cementing exploration technology;

6. In metallurgical industry, it is used as the filler of casting and welding workshop partition and as the material of sand core;

7. Adding proper amount of floating beads into vinyl plastics can make effective noise elimination equipment, which can reduce the noise from 95-100db to below 90dB. It can also be used in noise elimination coatings;

8. Making use of the high strength and wear resistance of new floating beads, we can make automobile brake pads, friction pads and oil drilling rig brake pads, which have the characteristics of good physical properties, long service life and low production cost.

4、 Chemical constituents of new pearlite floating beads

The chemical composition of new perlite floating beads is mainly silica and alumina.
