Because the net weight of green geotextile varies from 300 grams to 1500 grams per square meter, all of which are customized according to customer requirements or different construction projects. The specifications and models are 6 meters * 50 meters per roll, 300 square meters per roll, and can also be customized according to customer requirements. In the production and manufacturing of moisture-proof geotextiles, it is necessary to edge every corner of the top and bottom of each roll, which is about 1 kilogram per square meter. In other words, the overlapping edge of the 20cm steel bar should be left empty. People with a net weight less than 1 kilogram should not go out of the air from the welding edge, which is the fiber laser cutting edge. Because the geotextile film in the middle is too thin, it is important to weld the fiber laser cutting edge with a piece of non-woven geotextile by welding.
Green geotextile is a part of the composite material family for geotechnical testing, which is widely used in roads, high-speed railway lines, water conservancy and hydropower engineering projects, large, medium and small construction projects, power plant ash dam infrastructure, non-ferrous metal tailings treatment, environmental protection machinery engineering projects, environmental protection testing, etc.
The work shoes and general construction equipment worn on the construction site must not damage the non-woven geotextile. The construction site must not do anything with the non-woven geotextile that has already been constructed, such as smoking with sharp specialized tools or poking the non-woven geotextile.
Non woven geotextile is a high molecular weight polyester short fiber raw material produced by needle tying method, with high elongation at break and maximum elongation at break. The external sand surface of non-woven geotextile enhances the friction resistance between the inner surface and the surface, which is beneficial for maintaining the reliability, flexibility, and excellent corrosion and salt resistance of geotextile. In the same stable seepage control.
Silk spinning adhesive technology is one of the faster processing technologies in the development trend of green geotextiles and geotextile industries. The key processing technology of this processing technology is: cutting the polymer into slices; do spinning; Lashin; Laying nets; The production process of hot pressing bonding or needle unwinding is short, and the production efficiency is high. From prediction to finished product production and manufacturing, it only takes 20 minutes to go up and down. The actual operation personnel of the production line only need 3-4 people per shift, and the production and manufacturing speed reaches 250 × 300m/min. The product range is generally 2/6m, which can reduce the overlap of steel bars, facilitate engineering construction, and ensure the quality of engineering construction. This type of non-woven geotextile fabric has high compressive strength, high elongation, and is not easy to break or tear in the mesh.
In the process of ensuring product safety and protection, polyester geotextile products are not easily exposed to the sun for a long time. In storage and construction sites, attention should be paid to ensuring product safety and protection. Plastic film or other covering materials should be used to prevent sun and moisture.
