Analysis of technical parameters of fireproof board
Typical value of standard value of test item GB/T 17657-1999
Curved plate ( 0.6mm ) horizontal plate (1.0mm)
Surface wear resistance ≥ 350 rpm 700 rpm
24 hour water absorption --- -- 0.1%
Boiling water boiled weight gain <18.0% <2.0% 5.0% 0.7%
Thickness <20.0% <2.0% 10.0% 0.8%
Look no bubbling stratification, there is a slight color change without bubbling delamination, no change in color
High temperature resistance ( 1800C , 20 minutes) without bubbling cracking, slight change in color, no bubble cracking, slight change in color
Pollution - resistant - corrosion resistant physicochemical board - no effect
Pollution - resistant - anti - static physical board slightly affected no effect - slight impact
Impact resistance ( 1 meter height ball drop, dent diameter) 10mm 10mm 8mm 4.2-4.7mm
Tensile strength 55MPa 59MPa 71MPa 100.7MPa
Static bending strength -- -- -- 104.2MPa
Bending performance (minimum bending radius) --- 10 times the thickness --
