Abstract

The utility model relates to a cerium oxide polyester polishing fabric and disk. The utility model comprises a polyurethane foaming elastomer whose polyester fibers are reinforced, and the inner side of the utility model is provided with cerium oxide powders which are uniformly distributed. The utility model basically overcome the defects in the prior art, and the utility model can enhance the quality and efficiency of polishing.

Description

Cerous oxide-contg. polyester polishing fabric and disk

The utility model relates to a kind of kinescope and large-scale optical instrument polishing material, particularly a kind of cerium oxide Polyester polishing cloth and polishing disk of adding in advance.

Polishing cloth and polishing disk are the polishing materials that is used for kinescope surface and sealing surface, but at the import and the homemade polishing material of industrial usefulness, all are polyurethane foam elastomers of polyester fiber enhancing, do not add the cerium rouge abrasive material in the body.

Existing polishing cloth or polishing disk need to starch with cerium oxide abrasives in polishing process, the cerium oxide abrasives slurry absorbs to play the rubbing down effect by the microporous network structure on polishing disk or polishing cloth surface, in the rubbing down action, require in the polishing body certain abrasive material rate is arranged for reaching certain rubbing down efficient, also requiring has certain water liquid turnover amount in the polishing body, fricative heat can be taken away immediately, and to guarantee the mechanical performance of polishing body, existing polishing body cooperates abrasive slurries in use to have following defective:

1, in the general rubbing down running, the concentration of slip is about 7%, and the adsorption equilibrium time is longer, limited polishing velocity,, had only the concentration that improves slip in order to improve the cerium oxide concentration of polishing body, easily cause polishing body to skid this moment and water circulation deficiency, influence polishing efficiency and quality.

2, sometimes because of polishing body macropore skewness, cerium oxide is more to be concentrated in the big hole, makes kinescope be subjected to flour milling irregular, influences product quality.

3, blocking pipe causes stopping production to the polishing slip because cerium oxide precipitates in circulation.

4, cerium oxide slip sanitary condition in running is poor.

5, the cerium oxide consumption is big, makes the polishing cost very high.

The purpose of this utility model provides a kind of cerium oxide abrasives slurry, rubbing down efficient height, measured cerium oxide Polyester polishing cloth and polishing disk of adding in advance of matter of need not.

The purpose of this utility model realizes by following scheme:

A kind of cerium oxide Polyester polishing cloth and polishing disk of adding in advance, it comprises the polyurethane foam elastomer that polyester fiber strengthens, and doses even cerium oxide powder in the foaming elastomer.

The utility model can be brought in constant renewal in the surface in running, guarantee enough, uniform abrasive material rates, can not re-use abrasive slurries, and water replaces, and has overcome the defective of existing product basically, has improved rubbing down quality and efficient.

Fig. 2 is the utility model cross section enlarged diagram;

Below the contrast accompanying drawing is described in more detail structure of the present utility model by embodiment.

Embodiment:

The structure of original polishing body as shown in Figure 1, flexible entity (2) and hole (1) in the elastomer, in the polishing running, cerium oxide powder is starched the absorption of polished body hole, a polishing action.

Structure of the present utility model as shown in Figure 2, the utility model comprises the polyurethane foam elastomer that polyester fiber strengthens, dosed in the elastomer and marked hole (3) and entity (4) among equally distributed cerium oxide powder (5) figure, cerium oxide is uniformly distributed in the elastomer.

Claims

1, a kind of cerium oxide Polyester polishing cloth and polishing disk of adding in advance, it comprises the polyurethane foam elastomer that polyester fiber strengthens, and it is characterized in that having dosed in the above-mentioned polyurethane foam elastomer equally distributed cerium oxide powder.
