Description
Closed-pore Perlite(Obturator),its requires special size perlite
selected to be expanded after heating, and throgh precise control
of temperature and material stayed in air time, so that
special perlite surface melting, stomatal closure, while the
interior is honeycomb-like structure, being micro-spherical
appearance.Compared with traditional porous perlite, besides
thermal- insulation and acoustic insulation properties, its more
benefit is high intensity, low water absorbability and good
miscibility.
Main advantage
This product has high intensity, low water absorption and
easy separation etc.
Applications
For concrete to reduce the weight. Improve the water retention
properties, bonding properties and strength. As a better choice to
solve the hollowing and cracking problem of current mortar.
Can improve mortar's mobility, widely used in insulation mortar of
internal and external wall;
Used as decorative board and insulation board's light
aggregate;
Can replace part of the floating beads;
Used in construction, metallurgy, industrial furnace (light
firebrick aspects) and other industries
