Abstract
The invention relates to a liner with impact and wear resistance property, which is applicable for the liner of storage hoppers, bins and loading chutes of material transportation in the fields of mine, wharf, cement and steel, etc. The liner comprises a polyurethane board body with a plurality of alumina spheres thermo sulfurized in the surface; a bottom layer of the polyurethane board body is connected with a steel plate through an enforcement mesh which is fixedly connected with the steel plate and thermo sulfurized in the polyurethane board body; back screw holes are arranged on the steel plate, in which the polyurethane integrated with the polyurethane board are filled. The scaleboards are provided with nut lying holes and bolt reserved holes. The peripheral of the steel plate is covered by the polyurethane. In the invention, the firm connection of the polyurethane board body and the steel plate ensures higher impact resistance and wear resistance properties.
Description
technical field [0001] The invention relates to a wear-resistant liner, in particular to an impact-resistant wear-resistant liner. Background technique [0002] Wear-resistant liners are widely used in the lining of material transportation bins, hoppers, and chutes in mines, wharves, cement and steel industries, etc., to achieve impact resistance and wear resistance, so that the bins are not damaged. The wear-resistant liner in the prior art is to heat-vulcanize the polyurethane on the steel plate, make full use of the elasticity and wear resistance of the polyurethane, and achieve the purpose of wear resistance. However, in use, the polyurethane and the steel plate are detached under the action of strong impact force, which shows that the impact resistance is not enough. The impact resistance of polyurethane to sharp materials is not ideal, and the connection between the steel plate and polyurethane is not firm. In order to overcome wear resistanc...
