Product Overview

Description


Product Description

Non-combustion and heat-insulating

Perlite is an excellent fireproof material. The thermal conductivity of 50mm thick perlite core panel for fireproof door is only 0.064, which is far superior to other types of fire door core panels.

Light and strong

Low-density, high strength and high impact resistance due to double-layer wire mesh reinforced.

Sound-insulating and absorbing

Pure inorganic panel, the internal expanded structure ensures high sound insulation and sound absorption which can be hardly achieved by other door core panel.

Convenient to use

Can be sawed, planed, and engraved. No pollution during production, processing and construction installation, low labor intensity, no harm to operators

Manufacturing process

Expanded perlites are acidic volcano glassy lava, by smashing and sieving to a certain size, and then by preheating and sintering at 1300℃, turning into white or light colored particles, mixed with the inorganic glue, by press molding and drying, they are made into multi-application boards.

Advantages
\t
Performance
\t
Perlite panel
\t
Gypsum panel
\t
Environmental protection
\t
Pure natural, no fiber, non-toxic, and harmless. Does not contain any harmful substances, no pollution, no radioactivity. Be a new type of green material
\t
Contains a variety of additives, has pulverization phenomenon and environmental pollution
\t
Fire proof
\t
Inorganic material, noncombustible, fire proof grade A
\t
Low fire proof performance and fire-resistant limitation. Fireproof grade is B. Start to carbonize at 200℃
\t
Sound absorption
\t
Having a large number of through pores for absorbing the high-frequency wide-band noise
\t
The sound absorption and insulation performance is poor
\t
Water resistant
\t
Hydrophobic and dampproof. Does not deform and soften even under water immersion
\t
Moisture resistance and water resistance is low. Easy to deform, moulder, and soften.
\t
Thermal insulation
\t
Good insulation performance. The heat conductivity coefficient of air is low since the panel has a large number of micro air chambers
\t
Common performance
\t
Physical properties
\t
Its density is only half of the gypsum panel. The strength increased greatly due to steel-wire mesh reinforced inside. Outstanding performances of impact resistance, pression resistance, and antifracture
\t
Higher density, low strength without reinforcement.

Environmental protection
\t
Pure natural, no fiber, non-toxic, no gas volatilization, no radioactivity, no second pollution
\t
There are fiber contamination and surface coating which are harmful to human skin and respiratory system
\t
Fire resistant
\t
Inorganic materials, non-combustible material, fire resistant Grade A
\t
Smoking upon fire, carbonating in 500℃. Fire resistant grade is B1 in case of suspended installation
\t
Water absorption
\t
Hydrophobic and damp proof, non-deformation and non-softening even under water immersion. The construction work is free from humidity
\t
Non-hydrophobic. Easy to deform, soften, and fall off while meeting with water or high moisture. Can't carry out construction work in high humidity environment.
\t
Sound absorption
\t
No surface coating, there are a large number of through pores to reduce the high-frequency wide-band noise
\t
Surface coated, a large number of pores are blocked. Sound-absorbing effect is poor after moisture plugs the pores, due to its non-hydrophobic
\t
Physical properties
\t
Double metal mesh reinforced inside, high strength, good toughness, no deformation, no sag after long-term use
\t
Short service life, poor toughness, easy to deform and sag
\t
Appearance
\t
Double metal mesh reinforced inside, high strength, good toughness, no deformation, no sag after long-term use
\t
Unstable chemical property, easily oxidized surface coating. Easy to discolor.
