Description

Technical Field

[0001] The invention relates to the technical field of geogrid production equipment, in particular to a preparation process of a polygonal glass fiber geogrid with a stable structure. Background Art

[0002] The preparation process of polygonal glass fiber geogrid focuses on structural stability. Its production process includes key steps such as raw material preparation, weaving base material, directional structure process, coating treatment and drying. During the weaving process, the directional structure process is adopted to ensure that the yarn strength is fully exerted, which significantly improves the tensile strength, tear strength and creep resistance of the grid, thereby achieving structural stability.

[0003] The patent with application number CN202310277278.2 discloses an intelligent geogrid, a manufacturing device and a manufacturing method thereof. The intelligent geogrid is composed of several intelligent geogrid units extending longitudinally and transversely. The intelligent geogrid unit includes a central node; several extended strips arranged at intervals around the central node and located on the same horizontal plane, one end of the extended strip is connected to the central node, and the other end is connected to the adjacent intelligent geogrid unit; the geogrid also has good tensile and impact resistance, which solves engineering problems such as when the geogrid is damaged, it is difficult to detect due to the hidden usage scenario.

[0004] In the current geogrid production, alkali-free glass fiber is woven by a biaxial warp knitting machine and then directly enters the coating process and is impregnated with asphalt coating. Although the process is efficient, the semi-open environment makes it easy for dust, grease and other pollutants to adhere to the grid material during transportation, affecting the adhesion strength between the coating and the substrate and reducing the coating quality. At the same time, long-term operation of the coating equipment will cause the solid particles and pigments in the asphalt coating to settle, causing the coating to stratify, affecting the coating uniformity and performance indicators.

[0005] In view of this, we propose a preparation process of polygonal glass fiber geogrid with stable structure. Summary of the invention

[0006] The object of the present invention is to provide a process for preparing a polygonal glass fiber geogrid with a stable structure, so as to solve the problems raised in the above-mentioned background technology.
