Mesh cloth matrix produced through alkali-free glass fiber roving weaving and re-preparation and production method of mesh cloth matrix

Abstract

The invention discloses a mesh cloth matrix produced through alkali-free glass fiber roving weaving and re-preparation and a production method of the mesh cloth matrix. The production method of the mesh cloth matrix comprises the steps that mesh cloth obtained through alkali-free glass fiber roving weaving serves as a middle layer to be compounded with multiple layers of glass fiber mesh sheets, and the mesh cloth matrix produced through alkali-free glass fiber roving weaving and re-preparation is obtained. The mesh cloth obtained through alkali-free glass fiber roving weaving serves as the middle layer to be compounded with the multiple layers of glass fiber mesh sheets, the mesh cloth obtained through alkali-free glass fiber roving weaving is used for replacing mesh cloth materials of middle layers (the second layer, the third layer or the fourth layer) in a traditional glass fiber mesh cloth matrix, and therefore the quality, thickness, strength, service life and other characters ofthe mesh cloth matrix are guaranteed under the condition that the number of layers is reduced, the number of layers of the mesh cloth is effectively reduced, and the problems that in existing mesh cloth matrixes, energy consumption is large, and cost is high are solved.

Description

technical field [0001] The invention belongs to the technical field of grinding tools, and in particular relates to a mesh base body produced by weaving and re-preparing non-alkali glass fiber roving and a production method thereof. Background technique [0002] The existing disc-shaped coated abrasive "elastic grinding disc (louver)" mainly adheres abrasives or emery cloth to a substrate; when working, the substrate carries the abrasive to rotate the grinding workpiece, and the substrate is the net. Cloth body. [0003] At present, in order to ensure the support of the louver wheel by the mesh matrix, it is necessary to make the mesh matrix with multiple layers of glass fiber mesh, such as 8-12 layers of glass fiber mesh, so that the quality, thickness and strength of the mesh matrix can reach National standard. Most of the existing mesh base products are made by dipping and drying multi-layer glass fiber mesh sheets one by one, and then artificially combining them, which...

Problems solved by technology

[0004] In view of this, the purpose of the present invention is to provide a kind of method that weaves with non-alkali glass fiber roving and prepares the production net cloth substrate again, by using the net cloth that non-alkali glass fiber roving weaves as intermediate layer and multi-layer glass fiber web sheet composite , effectively reducing the number of layers of the mesh base, and solving the problems of large energy consumption and high cost of the existing mesh base
