Technical field
The utility model belongs to coated abrasive tool technical field, and in particular to what one kind was neither too hard, nor too soft bonds sponge sand lump
Body.
Background technique
Covering grinding tool is a kind of important grinding tool form, refers to and abrasive material is fixed on the flexible materials such as cloth, paper with binder
The tool that can be ground and be polished made of upper, is made of matrix, abrasive material and binder three parts.Since it has life
It produces that the period is short, manufacturing cost is low, service efficiency is high, grinding area is big, safe ready, the advantages that being widely used, obtains in recent years
It rapidly develops.Why it can take the course of its own in numerous grinding materials and grinding tool kinds, and the bonded abrasive tools such as grinding wheel, grinding stone and drive neat
It drives, is due to flexible substrate, with the characteristic of flexibility grinding, this is also the root that coated abrasive tool is different from other grinding tools
This.
The flexibility of coated abrasive tool is mainly determined that wherein matrix is abrasive material and binder by the property of matrix and binder
Supporting body and coated abrasive tool there is flexible leading factor.Matrix has a major impact the performance of grinding tool, and grinding tool makes
It is all closely bound up therewith with mode, wear resistance, the degree of roughness of grinding surface.Common matrix have paper (such as brown paper, latex paper),
Cloth (such as looped fabric, non-woven fabrics), film, sponge, type is more, and matrix is also the main according to form of coated abrasive tool classification.
In the common matrix of coated abrasive tool, cloth base is harder, and sponge base is softer, and paper base is between the two, therefore this three is selected to make
For the Typical Representative of different flexibility matrixes, corresponding emery cloth, sand sponge, sand paper are also the typical case of different flexibility coated abrasive tools
It represents.
Polishing abrasive tool currently used in the market is mainly in the majority with laminated sand paper, and small part sand paper directlys adopt sponge conduct
Substrate, mainly since sponge is relatively soft, it is easy to cause the loss of abrasive grain, i.e. abrasive material and sponge bonding force is poor,
And cause abrasive surface uneven, it is not used to the sanding and polishing of the higher equipment of surface accuracy, the i.e. hardness of sponge substrate
Not enough, structural instability.
