Female powder is 2~4 parts, and plate tension, flexural strength are preferable, meanwhile, inventors have found that wheat straw powder, flyash granularity, Blast Furnace Ore slag particle
Degree is affected to the flexural strength of plate, tensile strength and (is shown in Table 6), preferred 100 mesh of flyash granularity of the present invention, Blast Furnace Ore slag particle
10 μm of degree, 60 mesh of wheat straw Powder Particle Size, plate tension obtained, flexural strength are preferable.
6 flyash of table, the influence of wheat straw powder and blast-furnace cinder, particle size to the performance of plate
As can be seen that wheat straw Powder Particle Size is affected to the flexural strength of plate, tensile strength, and as wheat straw Powder Particle Size becomes
Greatly, flexural strength becomes larger, and tensile strength becomes smaller, may due to wheat straw Powder Particle Size differentia influence its in the reaction system point
The degree of dissipating, the lesser wheat straw powder of partial size disperse more uniform in system, therefore the distribution of chlorine O-Mg series internal void is equal in plate
It is even, plate compactness more preferably, more preferably so as to cause sample tensile strength.As wheat straw Powder Particle Size becomes larger, major diameter increases therewith, fiber
Length is longer, and since chlorine O-Mg series have good compatibility to wheat straw powder in plate, wheat straw powder can be filled into chlorine oxygen magnesium three in plate
In the skeleton of first system, and have crosslinking so that plate toughness is enhanced between fiber, flexural strength will increase.
Blast-furnace cinder granularity, flyash granularity have certain influence to the performance of plate, and granularity is smaller, increase and participate in aquation
The area of reaction improves the production quantity of hydrated product, is conducive to the intensity for improving plate.It but is not blast-furnace cinder granularity, fine coal
The thinner grey granularity the better, and after the fineness for reaching certain, the intensity of plate no longer increases with the raising of fineness of slag, can
Can due to undersized, crackle and gap inside slag in grinding process by soldering, compacting, to influence hydration reaction
It carries out, the intensity of plate no longer increases with the raising of fineness of slag.Inventor also found, when blast-furnace cinder granularity, fine coal
Soot particle spends hour, and the tensile strength of plate decreases instead, preferred 100 mesh of flyash granularity of the present invention, Blast Furnace Ore slag particle
