Our company has developed "HouYi" brand new, light-weight fire door core, expected from the investment and all aspects of storage products through rigorous testing, quality, and its characteristics with the following eight areas:
1, green, non-toxic harmless
"HouYi" brand fire door circuit board in the magnesium oxide, magnesium chloride, perlite and water on the basis of the quaternary system, modified by adding inorganic binder and reinforcing material, the foam curing, all of natural or biodegradable inorganic material, non-organic compounds, is an inorganic insulation foam board, was closed between the porous structure does not contain asbestos, formaldehyde, benzene and other harmful ingredients, non-toxic, tasteless, non-polluting, high temperature does not produce harmful gases, no spread of smoke, the "National Fire Protection Building Materials Quality Supervision and Inspection Center" type test, smoke toxicity to security level (AQ1), full compliance with national door core material and new national standard.
2, fire insulation, low thermal conductivity
"HouYi" brand fire door circuit board itself flammable, combustion through the "National Fire Protection Building Materials Quality Supervision and Inspection Center" type test, to A1 standard. Fire resistance of up to 90 to 120 minutes.
3, the density is low, uniform and compact
"HouYi" brand fire door circuit board by means of physical and chemical foam in the slurry, and modified by adding inorganic binder materials, under certain conditions, forming a hardened, without mechanical pressing, the core of this technology, the doors sheet, plate uniformly dense, low density, only 320Kg ± 20kg/m3, surface roughness, physical and chemical properties of stability, deformation and no cracking.
4, non-hygroscopic brine back, do not rust steel
"HouYi" brand fire door circuit board using new cementing material, while using water-repellent technology, closed foam, good moisture absorption, the total elimination of lead due to moisture absorption magnesium chloride, brine back to the phenomenon of air humidity in the South especially in Guangdong, long-term placement will not absorb moisture, brine back, virtually eliminating the role of steel corrosion, can be safely used in steel fire doors, fire doors for a variety of use.
5, excellent strength, bending pressure
"HouYi" brand fire door circuit board using chemical bond, a molding technology, under certain conditions, hardening of stereotypes, plates implanted in the core strength of polypropylene fiber line, mixing enhancement, crack short fiber, made into a PC circuit board, toughness, and bending pressure, has good mechanical strength.
6, to facilitate cutting, ease of processing
"HouYi" brand fire door circuit board material is uniform and compact, has good mechanical properties, easy processing, can be cutting, drilling, milling, stitching, and bonding. Milling template can be spent or used directly processed into the required concave door core, fire doors used to facilitate modeling.
7, surface roughness, porosity tiny
"HouYi" brand fire door core surface roughness, pores small, and the facade material bonding glue to eat less, reduce adhesive consumption, saving material costs. Flatten the surface treatment to further improve the circuit board surface flatness.
8, specifications and diverse, it can be a large plate
"HouYi" unique brand of cold fire door core molding process can be made of different specifications, the thickness of the large-sized circuit board, fire door specifications can be customized.
Specifications:
Size: General 2100mm × 900mm. Special sizes can be customized.
Thickness: 30mm, 35mm, 40mm, 48mm, 55mm and so on. Special specifications can be customized.
