1. Production process:
East 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 inorganic binder as the main material, after a whole set of process processing and inorganic environmental protection composite core board, is the replacement of rock wool, aluminum silicate door core material of a kind of natural green environmental protection fireproof material.
Perlite fire door core board
This product non-toxic, tasteless, non-combustible, corrosion of steel, 1100 ℃ high temperature melting deformation, combustion performance reached A level.Perlite fire prevention board to the latest research progress in order to adapt to the new national standard of fire door GB12955-2008 fire door filler material requirements, our company of perlite fire prevention board to do the further research, and introduced one to simulate GB7633-87 fire test method of the doors and rolling experiment furnace, fire endurance tests of perlite fire prevention board, furnace temperature curve fully carried out in accordance with the prescribed GB7633-87.The representative values of the time-temperature correlation are shown in the following table:
Time t (min) 5 10 15 30 to 60, 90, 120 ℃ temperature
556 659 718 821 925 986 1029
With the further specification of modern building energy saving and fire prevention requirements, rock wool, aluminum silicate (door core) has been forced out by the state.Perlite fire prevention (door core) board by modern fire doors and Windows (developed countries have generally used) by choice.
I. composition and structure
The main raw material of perlite gate core board is perlite.
Ii. Production technology
1. Selected materials: perlite with appropriate bulk density shall be selected as the main material, and neutral materials shall be selected as the binder.
2. Uniform mixing: add appropriate amount of special modified binders to perlite and use special agitator to mix evenly.
3, compression molding: will be mixed evenly into the high-pressure mechanical mold pressure.
4. Stripping and discharging: the molds shall be dried and packaged into finished products.
Stable performance, moderate bulk density (260-300kg/m3).
Sound insulation and heat insulation, small thermal conductivity (0.076w /m.k).
The finished product has high strength (1.0-2.5mpa /40-48mm thickness), and its strength can be reduced by no less than 10% after one year of immersion.
Water resistance, acid resistance, alkali resistance, salt tolerance, resistance to freezing and thawing, high temperature (> 1100 ℃).
Nonionic adhesive, neutral, non - corrosive to wood and metal.
Non-combustible, non-toxic and pollution-free (in line with GB/ t20285-2006 standard).
Fire resistance A1, in line with gb12955-2008 "fire door" new standards.
Note: the national standard A1 fire resistance performance index: 40-43mm / 100 min, 45-48mm can reach more than 120 min.
2. Features of east perlite fireproof (door core) plate:
A, environmental protection, natural, pollution-free, expanded perlite is a natural perlite ore, through above 1300 ℃ high temperature instant expansion of particles, structure of hollow honeycomb ball form);
B, fire (absolutely non-flammable), hate water, not aging, corrosion resistance;
C. Light weight, heat insulation, heat preservation and sound absorption;
D. convenient construction, with features of cutting and planing saw.
3. East perlite fireproof (door core) plate specifications:
300 500 (20, 30, 40, 50, 60, 80, 100, 120)mm;Or according to customer requirements design and processing.
By the national fixed fire extinguishing system and fireproof component quality supervision and inspection center according to gb8624-1997 "building material combustion performance classification method" inspection: the continuous combustion time is 0s, the quality loss rate is only 5 ~ 12%, the combustion performance reaches GB8624 class A.Perlite fire prevention board is made up of expanded perlite powder with high temperature fire adhesive by mould pressing it into bulk density in ㎏ (260-300 / m3), high refractoriness (> 1100 ℃), the compressive strength (0.9 2.0 MPa), small coefficient of thermal conductivity (0.051 W/M.K) or less, noncombustible, non-toxic, tasteless, no pollution and other advantages, through the national building materials test center testing combustion performance reached A level.Fire and heat insulation performance is higher than aluminum silicate cotton and rock wool, is the cost of low, fire performance, environmental performance is excellent new fire door filler material.
Suitable for wood fire doors, steel fire doors filling materials, aluminum silicate cotton, rock wool replacement products.
