Softwood fine grinding abrasive cloth

Abstract

The invention provides softwood fine grinding abrasive cloth, and relates to abrasive cloth for metal grinding and polishing, in particular to fine grinding abrasive cloth. The softwood fine grinding abrasive cloth adopts the following process steps: 1, unreeling; 2, impregnation; 3, coating; 4, press polishing and forming; 5, winding; 6, unfolding of a file and trademark printing; 7, base rubber coating; 8, softwood grain sand planting through vibration and gravity; 9, predrying; 10, coating of rubber covering and abrasive material; 11, main drying; 12, rolling; 13, unreeling; 14, coating of the rubber covering; 15, main drying; 16, solidification; 17, bending; 18, coiling; and 19, warehousing. The softwood fine grinding abrasive cloth has the characteristics of waterproofness, good grinding and polishing performance, high anti-blockage capability, and the like. Particularly, the softwood fine grinding abrasive cloth has extraordinary performance in maintaining the consistent surface finish. The softwood fine grinding abrasive cloth is suitable for high-speed grinding which is carried out in the presence of cooling water.

Description

Technical field: [0001] The invention relates to an abrasive cloth for metal grinding and polishing, in particular to a fine abrasive cloth. Background technique: [0002] At present, the domestic high-grade grinding materials are widely used in a large amount, and the annual consumption is about 200 million square meters. The domestic paint abrasive products are of low grade. Especially in terms of wear resistance and water resistance, it has poor performance. There is a lack of suitable high-speed grinding products, especially in terms of water resistance. The water-resistant products used in China are still at the level of the 1960s. The specific manifestations are: (1) Water resistance, after soaking in water, the abrasive cloth becomes soft as a whole. Cutting efficiency is low. (2) The alkyd resin used has low bonding strength, the abrasive is easy to fall off during use, and the wear resistance is poor. (3) The adhesive used is brittle, the abrasive cloth is easy t...

Especially in terms of wear resistance and water resistance, the performance is poor

There is a lack of suitable high-speed grinding products, especially in terms of water resistance. The water-resistant products used in China are still at the level of the 1960s. The specific performance is: (1) Water resistance. Low cutting efficiency

(2) The alkyd resin used has low bonding strength, the abrasive is easy to fall off during use, and the wear resistance is poor

(3) The adhesive used is brittle, and the emery cloth is easy to age, and cracks will appear after being placed for about two months, which will seriously affect the performance
