Anti-hardening cement packaging bag

Abstract

An anti-hardening cement packaging bag includes a diffusion structural layer, an outer protective layer and connecting grids; the diffusion structural layer is disposed at the innermost of a packagingbag, and the outer protective layer is disposed at the outermost of the packaging bag; the connecting grids are used for connecting the diffusion structural layer and the outer protective layer, andthe connecting grids evenly separates the diffusion structural layer and the outer protective layer into individual pieces; the diffusion structural layer is internally provided with a plurality of diffusion units which are uniformly dispersed; and the diffusion units are of a funnel-type structure, and openings near the inner cement portion is large, and outer openings away from the cement portion is small. According to the anti-hardening cement packaging bag, the defect of hardening of traditional bagged cement after placement is solved, the natural environment is protected, and the waste ofnon-renewable resources is greatly reduced; and the production is easy, the processing and manufacturing cost is low, and the problems of difficult packaging, difficult transport and difficult placement of cement are solved.

Description

technical field [0001] The patent of the invention relates to the technical field of cement packaging and transportation, in particular to an anti-hardening cement packaging bag. Background technique [0002] Cement is an active substance. If it is stored for a period of time, it will weather and deteriorate and lose part of its activity if it is not well preserved; during the storage period, cement fine powder is very easy to chemically react with water vapor and carbon dioxide in the air. Although this reaction is slow, However, due to the continuous process, there will also be changes from quantitative change to qualitative change; therefore, even if the cement stored for a long time is not directly in contact with liquid water or exposed to the air, agglomeration, granulation and Reduction of activity and other phenomena; the degree of indirect moisture absorption of cement is related to the storage time, storage conditions and types of cement. The same cement is stored ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above technical problems, the present invention provides an anti-hardening cement packaging bag. The packaging bag adopts an optimized structural design, and through a natural diffusion structure, it cleverly solves the shortcomings of the traditional cement packaging bag and solves the problem of packaging The problem of large-scale hardening of cement, and after one-time mold opening, the manufacturing cost is very low, which is suitable for the large-scale promotion and application of bagged cement;
