Mountain flour is as filler material, and while reducing finished product board cost, there are also certain effects for preventing deformation, and can
Reduce the wet rate that rises of finished product plate.
Vinylon fibre substitutes part wood pulp cellulose, can increase timber intensity, and reduce plate water absorption rate, prevent plate from opening
It splits.Wood pulp cellulose can adsorb cement particle well, be pressurizeed by great tonnage press, guarantee the bonding of fiber and substrate, make it
With hydrated product it is cementing more sufficiently, so that finished product plate be made to have physically better mechanical property.
When wood pulp cellulose is in 3.5%-4% content, because its water imbibition can promote the hydration reaction of cement inside plate, increase
Timber intensity due to its water imbibition, causes plate water content excessively high, causes plate loose, lead to plate when content is greater than 4.5%
Strength reduction, so the content selection of wood pulp cellulose is most important.
Cement upon hardening, plays lubricating action, assigns the certain workability of mixture, is that cracking resistance becomes the cementing of non-evaporating pressing plate material
Material, aquation is concrete after cement meets water, provides intensity for finished product plate.
The additives such as a small amount of aluminium powder, aluminium hydroxide, can improve the dry-shrinkage deformed problem of finished product plate, plate to a certain extent
It is stable and reliable for performance after maintenance.When the aluminium powder of addition and aluminium hydroxide additive are in 3-5%, former material is contributed to as swelling agent
It in material, mixes water and generates a large amount of expansion crystallographic hyrate-hydrated calcium aluminate sulfates (i.e. ettringite), generate the reaction of raw material cement
The generation process shunk, while wood pulp cellulose and vinylon fibre in tight raw material have been postponed in appropriateness expansion, are improved fine
The bond stress of dimension and cement matrix guarantees the close connection of substrate, enhances plate stability.During hardening of cement, work as plate
When starting to shrink, expansion crystallographic hyrate-aquation sulphur aluminic acid that the aluminium powder and aluminium hydroxide additive of addition are generated in 3-5%
Calcium (i.e. ettringite) its stretching resistance can substantially resist shrinkage stress, to prevent plate dry-shrinkage deformed, to raw after hardening of cement
It is strong that plate can be increased at the entringite of stable plate finished product, and generation.When addition aluminium powder and aluminium hydroxide additive not
When to 3%, expansion crystallographic hyrate-hydrated calcium aluminate sulfate (i.e. ettringite) amount of generation is not reached requirement, and can not offset plate
The shrinkage stress generated is shunk, so that not having prevents dry-shrinkage deformed effect.When aluminium powder and aluminium hydroxide additive are greater than 5%
When, stretching resistance caused by expansion crystallographic hyrate-hydrated calcium aluminate sulfate (i.e. ettringite) of generation is greater than panel shrinkage and generates
Shrinkage stress, cause plate dilatancy.Aluminium hydroxide in plate finished product after-hardening as working.
Certainly, the above description is not a limitation of the present invention, and the present invention is also not limited to the example above, this technology neck
The variations, modifications, additions or substitutions that the technical staff in domain is made within the essential scope of the present invention also should belong to of the invention
Protection scope.
