< R : b①<: bLong fire-resistant time: Due to the use of advanced thermal expansion fire prevention technology, the product has a long fire-resistant time. After inspection by the National Fireproof Building Materials Supervision and Inspection Center, the fire resistance time is more than < r b <: b. After testing by our company's laboratory, the fire resistance time is more than < r b <: b minutes, exceeding the national standard of < r b <: b hours. < R : b②<: bLong validity period: Due to the use of inorganic expansion materials and a small amount of high-efficiency adhesive materials, accelerated aging tests have proven that the validity period can reach < r b<: b years or more. Fire retardant packages are generally valid for three years. < R : b③<: bGood water and oil resistance: Tests have proven that the product will not swell, deform or collapse after being immersed in water and diesel oil for < r b<: b years. < R : b④<: b High mechanical strength and elasticity: Due to the use of non-toxic organic polymer materials for glue molding and solidification, the measured compressive strength < r b <: b is higher than the national standard (< r b <: b) < r b < : b times, which is < r b <: b times of the fire-retardant package (< r b <: b). : : b br bb br Construction method
