Stone flour is as inserts, while finished product board cost is reduced, and also certain prevents the effect of deformation, and can
Reduce the wet rate that rises of finished product sheet material.
Vinylon fibre substitutes part wood pulp cellulose, can increase timber intensity, and reduces sheet material water absorption rate, prevents sheet material from opening
Split.Wood pulp cellulose can adsorb cement particle well, be pressurizeed by great tonnage press, it is ensured that the bonding of fiber and base material, make it
With hydrated product it is cementing more fully so that finished product sheet material has physically better mechanical property.
When wood pulp cellulose is in 3.5%-4% contents, because its water imbibition can promote the hydration reaction of cement inside sheet material, increase
Timber intensity, when content is more than 4.5%, due to its water imbibition, causes sheet material water content too high, causes sheet material loose, causes sheet material
Intensity decreases, so the content selection of wood pulp cellulose is most important.
Cement upon hardening, plays lubrication, assigns the certain workability of mixture, is that cracking resistance becomes the cementing of non-evaporating pressing plate material
Material, it is concrete that cement, which meets aquation after water, and intensity is provided for finished product sheet material.

It is stable and reliable for performance after maintenance.When the aluminium powder and aluminium hydroxide additive of addition are in 3-5%, former material is contributed to as swelling agent
In material, mix water and generate a large amount of expansion crystallographic hyrate-hydrated calcium aluminate sulfates（That is ettringite）, make the reaction generation of raw material cement
Appropriateness expansion, has postponed the generation process shunk, while wood pulp cellulose and vinylon fibre in tight raw material, improve fine
Dimension and the bond stress of cement matrix, it is ensured that the close connection of base material, strengthen sheet material stability.During hardening of cement, work as sheet material
When starting to shrink at, expansion crystallographic hyrate-aquation sulphur aluminic acid that the aluminium powder and aluminium hydroxide additive of addition are generated in 3-5%
Calcium（That is ettringite）Its stretching resistance can substantially resist shrinkage stress, so as to prevent sheet material dry-shrinkage deformed, treat life after hardening of cement
Into stable sheet material finished product, and can to increase sheet material strong for the entringite produced.When addition aluminium powder and aluminium hydroxide additive not
During to 3%, expansion crystallographic hyrate-hydrated calcium aluminate sulfate of generation（That is ettringite）Amount do not reach requirement, it is impossible to offset sheet material
The shrinkage stress produced is shunk, so that not having prevents dry-shrinkage deformed effect.When aluminium powder and aluminium hydroxide additive are more than 5%
When, expansion crystallographic hyrate-hydrated calcium aluminate sulfate of generation（That is ettringite）Produced stretching resistance, is produced more than panel shrinkage
Shrinkage stress, cause sheet material dilatancy.Aluminium hydroxide in sheet material finished product after-hardening as working.
