Problems solved by technology

Due to the poor flatness of the surface of the dam bag, it is necessary to add a flat sheet at the part where the two dam bags are connected to each other. Since the flat sheet is made of rubber material, it has high fluidity during high temperature hot pressing and is easy to Offset and dislocation occur, so that the used flat sheet cannot be glued to the staggered layer of the dam bag tower connection, thereby reducing the overall performance of the rubber dam bag. In addition, the flat sheet also has the defect of easy aging, which leads to the failure of the tower connection. The layer is easy to crack, causing safety hazards and reducing the safety factor of the dam bag when used

Abstract

The invention relates to a dam bag of a rubber dam and a processing technology thereof, belonging to the technical fields of dam bags of the rubber dam and a production method thereof. The dam bag of the rubber dam comprises successively-connected dam bodies, a unvulcanized rheid section is used for connecting adjacent dam bodies, the dam bodies and the rheid sections are in an integral structure, the number of the dam bodies 1 is more than or equal to 2, ranging from 2 to 10, and the rheid section 4 is a rubber rheid. The processing technology comprises the following steps: 1) folding; 2) separating; 3) vulcanizing and shaping at one time; and 4) flattening. As for the dam bag of the rubber dam and the production method thereof provided by the invention, the dam is long in service life, convenient in processing and high in safety coefficient, and the breadth of the dam bag is as much as 10m.

Description

technical field [0001] The invention relates to a rubber dam bag and a processing technology thereof, and belongs to the technical field of rubber dam bags and production methods thereof. Background technique [0002] At present, when producing rubber dam bags, single-width vulcanization with a flat vulcanizer is generally used, and the width of the dam bags produced is only less than 1.1 meters. Due to the short width and length, several dam bags need to be connected to each other in actual use Tower joints are used to increase the width, so there is a tower joint within less than one meter along the length of the dam. Due to the poor flatness of the surface of the dam bag, it is necessary to add a flat sheet at the part where the two dam bags are connected to each other. Since the flat sheet is made of rubber material, it has high fluidity during high temperature hot pressing and is easy to Offset and dislocation occur, so that the used flat sheet cannot be glued to the s...
