Tai'an Wolong Engineering Materials Co., Ltd. outlines several key technologies here:

Geotextile Reinforcement Technology

Compared to steel, geogrids offer advantages in corrosion and chemical resistance, but are susceptible to ultraviolet radiation, aging, or temperature limitations (-50~80℃). Therefore, it is necessary to add appropriate carbon black to the manufacturing materials of geogrids to enhance their weather resistance, and it is also essential to implement surface protection measures such as fillers or vegetation in engineering applications to improve the anti-aging properties of geogrids.

2. Soil reinforcement grid tensioning technology

The geogrid stretching technology blends high-density polyethylene or polypropylene with modifiers and additives. The extrusion press rolling process produces excellent sheets with high thickness control accuracy and smooth surfaces. After the polymer molecular chains are precisely cut by a punch press and slowly stretched by a preheating device, they are highly oriented along the stretching direction.

3. Geotextile Creep Technology

During the use of geogrids, the long-term creep of geogrids is caused by the long-term effect of stable tension, which leads to the inability of the geogrid to effectively perform its intended reinforcing and tensile functions. Research on geogrid creep technology is of great significance to engineering safety.
