what is Hollow glass microspheres?

The characteristics of Hollow glass microspheres , light quality, small density, good thermal insulation performance

Beads have very good reflection effect to ultraviolet ray, prevent yellowing coating aging.

Beads high melting point, greatly improve the coating temperature resistance, good fire prevention effect

Beads of spherical particles have a bearing, friction small, can increase the flow of the coating film performance, and make the construction more convenient.

Effectively enhance the coating adhesion. Low oil absorption properties of glass beads make more resin can participate in the film, which largely improve the coating adhesion.

Hollow glass beads spherical structure makes it has good dispersion effect to the impact and stress, added to the coating can be very good improve coating outside force impact resistance, but also can reduce the coating stress cracking because of the heat bilges cold shrink.

Hollow glass beads particles as closed hollow sphere, added into the coating form independent adiabatic many micro cavity, thus greatly improve the coating to the heat and sound insulation, have very good insulation and noise reduction effect. Make the coating more waterproof, anti-fouling, corrosion resistant performance. Beads chemical inert surface chemical resistance, as a membrane glass beads when particles are close, low porosity formation, the coating surface of moisture and ions have a resistance to corrosion protective film, have very good protection effect.

How do I filter glass beads

Compared with the international advanced screening methods, my home is still relatively backward, at home, using dry mechanical separation methods, with gravity separation sieve is the separation of the hollow glass microballoon equipment.

Classifier is by gravity separation, classifier is made up of three sizes of settling tank. In the bottom of each sedimentation tank, a discharging device, when the air flow from the inlet pipe to settling tank containing fly ash, due to the increase of flow channel section, make the gas velocity drops rapidly, fly ash by gravity itself. Some gradually falling into the sedimentation tank, according to the principle of such drop, the heavier coarse particle, honeycomb vitreous, quartz, mullite, solid bead, iron bead and most large granular particles sedimentation in the classifier.

Separator is used in the process of airflow rotating inertial centrifugal force acting on the particles, the particles separated from the air. The main form of separator is a set of cyclone separator, channel down by subsidence case tiny cenosphere, along with the air flow into the separator, after two stage cyclone separation, is able to make most of the small hollow microsphere, sorting out, the remaining very little super fine pearl with airflow into the collector.

Collector at the end of the separating device, it is both a purification treatment device, and recovery of super fine pearl collector. Process USES a pulse bag-type collector, it can be chose by the separator not down most of the super fine pearl collected.
