Description

Sand paper with detachable dust removal structure

[ technical field ] A method for producing a semiconductor device

The utility model relates to an abrasive paper, concretely relates to dust removal structure's abrasive paper can be dismantled in area.

[ background of the invention ]

Conventional abrasive paper can produce a large amount of dust or granule when polishing the work piece, if do not clear up then can influence the effect of polishing, and there are some abrasive paper that can remove dust on the market at present, but the dust removal structure of this kind of abrasive paper has certain life, need change together with abrasive paper after using longer a period, the extravagant cost.

In order to overcome the problems, a sand paper with a detachable dust removing structure is developed.

[ Utility model ] content

The utility model aims to solve the technical problem that a to provide one kind has and can dismantle dust removal structure, can detach the dust when polishing the work piece, further improves the abrasive paper of the effect of polishing.

In order to realize the purpose, the utility model discloses a technical scheme: the utility model provides a sand paper of dust removal structure can be dismantled in area, it includes basic unit, viscose layer and abrasive material layer, the basic unit top bonds with the viscose layer, viscose layer top bonds with the abrasive material layer, the top on abrasive material layer is equipped with dull polish granule, and the top on abrasive material layer still is equipped with a plurality of magic subsides a, it has the fine hair piece of taking magic subsides b to bond on the magic subsides a.

In one or more embodiments, the top of the abrasive layer has a concave surface, the magic tape a is located in the concave surface, and the fluff block is adhered to the magic tape a and then is flush with the top surface of the abrasive layer.

In one or more embodiments, the substrate is a sponge.

In one or more embodiments, the material of the base layer is polyether sponge or ethylene-vinyl acetate copolymer or polyurethane.

In one or more embodiments, the base layer has a thickness of 4-8 mm.

The utility model discloses compare produced beneficial effect with the background art:

by adopting the technical scheme, the utility model discloses an abrasive paper has detachable fine hair piece, can detach the dust when polishing the work piece, further improves the effect of polishing, and the fine hair piece can be dismantled fast and change, has practiced thrift use cost, and it is simple and convenient to use.

[ description of the drawings ]

Fig. 1 is a schematic structural diagram of the present invention.

[ detailed description ] embodiments
