Geogrid is a kind of main geosynthetics. Compared with other geosynthetics, geogrid has unique performance and efficacy. It is commonly used as reinforcement material of reinforced soil structure or composite material.
The application of ultrasonic welding technology in plastic industry has become more and more popular in the world. Because the application of this technology can replace the flux, adhesive and other mechanical fixation methods needed in the old production, it can improve the production efficiency and quality, reduce the cost and reduce the pollution to the environment.
The plastic geogrid is characterized in that the shape of the grid hole in the geogrid is triangular, and the geogrid is formed by extrusion. The joint of the geogrid hole is provided with a circular weight reducing hole. The material of the geogrid is polypropylene. The utility model is ingenious in design and simple in use. By changing the shape of the grid hole, the gravity stretching direction of the grid is changed. In the practical engineering application, the utility model can adapt to the needs of different environments, improve the bearing capacity of the subgrade, and extend the service life of the subgrade.
The rib is a kind of high molecular plastic with high tensile strength. The joint of longitudinal and transverse ribs is welded by high frequency ultrasonic wave, which ensures the stability of product quality and the effective locking of grid grid on soil. At the same time, the strength of the grid can change the tension of the rib and adjust the number of the rib to design different models and specifications. In order to meet the needs of different projects and various technical indicators.
Kindly check the AMPLITUDE REFERENCE GUIDE for ULTRASONIC WELDING (in Microns (um)) table in the next page, you will find suit frequency for your application.
The benefits of ultrasonic welding are that it is much faster than conventional adhesives or solvents. The drying time is very quick, and the pieces do not need to remain in a fixture for long periods of time waiting for the joint to dry or cure. The welding can easily be automated, making clean and precise joints; the site of the weld is very clean and rarely requires any touch-up work. The low thermal impact on the materials involved enables a greater number of materials to be welded together.
