NFJ**6A (Metal explosion-proof flooring material)

Product Description: 

   NFJ**6A metal explosion-proof floor material is a new type of metal aggregate with high wear resistance and antistatic property. The aggregate has been treated with NFJ patented technology, which not only acts as filler, but also promotes the crystallization of cement stone, making the colloid become crystal or quasi-crystal, with secondary strengthening capability. Its metallographic structure is detailed as follows: its matrix is the pearlite, ferrite; its second phase is graphite, iron phosphide eutectic; therefore it can preferably bond with concrete and integrated as one without peeling off. Water cement ratio is small, compactness is high, and impermeability (water, oil) is strong.

     Upon the test and inspection of National Center for Quality Supervision and Test of Building Engineering Materials, the wear resistant performance on the NFJ**6A construction surface is better than that of artificial marble, emery and other frequently-used wear-resistant materials, and its abrasive resistance is *0 times that of cement mortar, and its fracture resistance, crush resistance, impact resistance, dry shrinkage resistance, seasoning crack resistance, expansion resistance and durability are very better.    

      NFJ**6A has stable electrical conductivity and the surface resistance of its anti-static test piece is up to 5 x****1 x**6Ω; its conductive, anti-static and metallic powder has longer service life, less heat conduction and surface hydration heat. Meanwhile, NFJ**6A satisfying the national standard for flame-retarded floor is the flame-retarded floor.

      Through special treatment, NFJ**6A aggregates plays not only the role of packing, but also accelerating set cement to crystallize and making colloid become crystal or crystalloid, and enabling them have the second strengthening capability. Additionally, NFJ**6A aggregate after treated by the dual high-composite anti-rust technology, has the permanent anti-rust capacity.



Application scope

Places with high load, high wear-resistance and high impact resistance

Places with higher explosion-proof requirements

The floor of the places with high electrostatic sensitivity

Places with higher oil permeability resistance

The locations that are risky of oil spilling and needs the oil-proof shelters.

The product applies to the rebuilding of concrete ground.



Advantages and Features:

The floor is of ultra-high rigidity and tenacity.

The appropriate particles and grading meet the ground requirements from smoothing to anti-slippery. Two functions of preventing electrostatics and flame-resistant, applicable to the explosive and flammable production areas and storage areas;

High surface density, high water/oil permeability resistance, anti-rust, saline-alkaline tolerance and weak acid tolerance.

The product applies to the rebuilding of concrete ground.

The combustion level is Level A1.

The product may be synchronized with concrete pouring, and thus helpful to shorten construction period.
