Perlite fire board, perlite insulation board, perlite fire brick, perlite outer wall fire barrier, perlite fire board price, perlite fire board use, perlite fire board characteristics, perlite fire board production plant.

1. Production process:

Xiangdong Perlite Fire Door Core

Perlite door core board (also known as: perlite fire door core board), is expanded perlite, high temperature resistant inorganic aggregate, high temperature resistant

The inorganic binder is the main material, and the inorganic environmental protection composite core board processed through a whole set of processes is an alternative.

A natural green fireproof material for core materials such as rock wool and aluminum silicate.

Perlite fire door core board perlite fire door core board This product is non-toxic, tasteless, non-combustible, non-corrosive steel plate

, 1100 ° C high temperature does not melt without deformation, detection of combustion performance to A grade. The latest research on perlite fireproof board

The research progress is to meet the requirements of GB12955-2008 fire door national new standard for fire door filling materials.

Our company has made further research on perlite fireproof board and introduced one to simulate GB7633-87.

The experimental furnace of "Fire Test Method for Doors and Rolling Curtains" tested the fire resistance of perlite fireproof panels.

The furnace temperature rise curve is completely in accordance with the following diagram specified in GB7633-87. Medium time-temperature

The representative values ​​of the system are shown in the following table: Time t(min) 5 10 15 30 60 90 120 Temperature °C

556 659 718 821 925 986 1029 With further specification of energy efficiency and fire protection requirements for modern buildings,

Rock wool and aluminum silicate (gate core) have been eliminated by the state. Perlite fireproof (door core) panels are modern fireproof

Doors and windows (commonly used in developed countries) are selected.

First, the composition of the structure

The main raw material of the perlite door core board is perlite, and the formula component material has a modified binder, a high-quality curing agent and the like.

Second, the production process

1. Selected materials: Perlite with suitable bulk density should be used as the main material, and neutral materials should be used as the binder.

2, uniform mixing: add the appropriate amount of special modified binder in the perlite, stir with a special mixer.

3. Press forming: The mixing mixture is fed into a high pressure mechanical mold to apply pressure.

4, demoulding and discharging: the sheet of the mold is dried and processed into finished product packaging.

Third, technical performance

Stable performance and moderate weight (260-300kg/m3).

Sound insulation, low thermal conductivity (0.076W/mk).

The strength of the finished product is high (1.0-2.5Mpa/40-48mm thickness). The annual strength of the water is not less than 10%.

Water, acid, alkali, salt, freeze and thaw, high temperature (>1100 ° C).

Non-ionic adhesive, neutral, non-corrosive to wood and metal.

Non-combustible, non-toxic, pollution-free (in accordance with GB/T20285-2006 standard).

Refractory A1 grade, in line with the new standard of GB12955-2008 "Fire Door".

Note: National Standard A1 fire performance index: 40-43mm / 100 minutes or more, 45-48mm can reach more than 120 minutes.

2. Features of the east pearlite fireproof (door core) board:

a, environmentally friendly, natural, non-polluting (expanded perlite is a natural perlite ore, which is formed by a hollow honeycomb-like particle spheroid with an instantaneous expansion at a temperature above 1300 °C);

b, fire (absolutely non-combustible), drowning, non-aging, corrosion resistance;

c. It has light weight, heat insulation, heat preservation and sound absorption;

d, convenient construction, with the characteristics of cut, sawing and so on.

3. Specifications of the east pearlite fireproof (door core) board:

300 × 500 × (20, 30, 40, 50, 60, 80, 100, 120) mm; or according to customer requirements design processing.

4. Performance:

Quality supervision and inspection of national fixed fire extinguishing systems and fire-resistant components

The center is tested according to GB8624-1997 "Classification Method of Combustion Performance of Building Materials": continuous burning time is 0s,

The mass loss rate is only ≤5~12%, and the combustion performance reaches GB8624 Class A. Perlite fire board is expanded

Expanded perlite powder plus high temperature fireproof adhesive pressed through the mold to have a bulk density (260-300kg/m3)

High refractoriness (>1100°C), high compressive strength (0.9-2.0MPa), low thermal conductivity

(≤0.051W/MK), non-combustible, non-toxic, odorless, non-polluting, etc.

The National Building Materials Testing Center tested combustion performance to Class A. Fire and heat insulation performance

Higher than aluminum silicate cotton and rock wool, it is a new type of anti-cost, fireproof and environmentally friendly

Fire door filling material.

5. Application:

It is suitable for the filling materials of wooden fire doors and steel fire doors. It is an alternative to aluminum silicate cotton and rock wool.
