Fiberglass Geogrid Production Equipment

The fiberglass geogrid production equipment is a set of high-performance industrial equipment system dedicated to the production of glass fiber reinforced geogrids. The equipment realizes high-strength directional weaving and resin compounding of the grid structure through key processes such as warp knitting, impregnation coating, drying and shaping of glass fiber yarn, and finally forms a glass fiber geogrid with high tensile strength, strong corrosion resistance and excellent dimensional stability.
Fiberglass geogrid is a reinforced geotechnical material made of alkali-free glass fiber as the main raw material, which is compounded with polymer coating after special surface treatment. It is widely used in foundation and structural reinforcement projects such as roads, railways, airport runways, ports and docks, bridges, slopes, dams, etc. It has excellent tensile resistance, high temperature resistance and creep resistance, and is one of the ideal reinforcement materials for high-grade infrastructure construction on the market.
As various types of infrastructure construction put forward higher performance, longer life and more environmentally friendly requirements for geosynthetics, fiberglass geogrids are widely promoted due to their excellent comprehensive performance, and the supporting production equipment is also continuously improving in terms of intelligence, high speed and automation.

◆ Equipment Composition

The manufacturing process of fiberglass geogrid is relatively complicated, requiring high-precision and high-stability mechanical equipment to cooperate with multiple process links to ensure the mechanical properties and stable quality of the product. The entire production line mainly includes the following key modules:
1. Fiberglass yarn unwinding system
This part uses multiple sets of tension-adjustable fiberglass warp and weft unwinding racks, equipped with active constant tension control devices to ensure that the fiberglass yarn does not knot or break during high-speed operation, ensuring the accuracy and stability of the weaving process.
2. Warp knitting system
Use a dedicated warp knitting machine or flat mesh weaving equipment to weave the fiberglass warp and weft into a mesh structure. This link determines the basic grid shape (such as 30×30, 50×50mm, etc.) and the longitudinal and transverse tension distribution structure of the grid. Modern equipment supports high-density, low-deviation high-speed weaving to ensure the consistency of the mechanical properties of the grid.
3. Coating and dipping system
The woven fiberglass grating needs to be treated with dipping coating, which is usually coated with asphalt, polyvinyl alcohol, water-soluble polymer or PVC coating liquid to enhance the wear resistance, corrosion resistance and friction between the glass fiber surface and the soil. The equipment is equipped with multiple coating tanks and automatic metering pump systems, which can automatically mix and evenly dip according to the formula.
4. Drying and shaping system
The coated grating will be dried and heat-shaped through a hot air drying furnace. The equipment has precise temperature control, multiple temperature zones and an online temperature monitoring system to ensure that the coating is evenly dried without deformation, and improve the dimensional stability and coating adhesion of the final product.
5. Traction and winding system
The dried fiberglass grating is sent to the automatic winding device through a constant tension traction device. The whole roll of finished product has uniform tension and neat edges. It can automatically trim the edges and automatically roll at a fixed length to meet the requirements of batch continuous production.
6. Electronic control system
The entire line adopts a PLC centralized control system, with a touch screen human-machine interface to achieve real-time monitoring and adjustment of process parameters such as temperature, speed, tension, and glue coating amount. The equipment supports intelligent functions such as recipe management, remote diagnosis, and automatic alarm, greatly improving operational convenience and production stability.

◆ Features

2. Uniform coating and strong adhesion
The independently designed coating system and efficient drying device can ensure that the coating is firmly adhered and the surface is uniform, enhancing the durability, aging resistance and chemical corrosion resistance of the grid, and extending the service life of the product.
3. Highly automated and easy to operate
From raw material unwinding to finished product winding, the entire line is fully automatically controlled, greatly reducing the frequency of manual operation, reducing labor intensity, reducing human errors, and improving product consistency and qualified rate.
4. Energy saving and environmental protection, stable operation
The equipment has high thermal energy utilization efficiency and is equipped with an environmentally friendly dust removal system, which meets the national energy conservation and emission reduction requirements; the entire line operates stably, has low maintenance costs, supports long-term continuous operation, and is suitable for industrial mass production.
5. Flexible customization, support for multiple specifications switching
The grid aperture, coating type, width (commonly 1m, 2m, 3m, etc.) and warp and weft yarn density can be adjusted according to customer needs to meet the application requirements of different markets and engineering projects.

◆ FAQ

What are the requirements for raw materials in the production process of fiberglass geogrid?
Fiberglass geogrid mainly uses alkali-free glass fiber yarn as raw material, which requires uniform yarn, stable tension, and not easy to fuzz, suitable for warp knitting or flat weaving. In order to enhance adhesion, surface treatment is required, and it is used with suitable coating materials (such as modified asphalt or polymer resin) to ensure the strength and durability of the finished grid.

  
What product specifications does this equipment support? Can it be customized?
The equipment supports a variety of grid specifications, such as 25×25mm, 30×30mm, 50×50mm and other common sizes, and can also customize products with a width of 1 meter to 3 meters. By changing the weaving template, adjusting the coating thickness and coating type, it can flexibly meet the requirements of different projects for strength, flexibility and coating performance.
