Compared with woven geotextiles, non-woven geotextiles have relatively low strength, but have high production efficiency, are relatively inexpensive, and have good performance, especially for easy processing into wide-width products, and can be made into various geosynthetics by processing. The material is therefore growing rapidly. According to different methods of forming and fixing, it can be generally divided into three categories: spinning clay rags, staple fiber needled geotextiles and hot-melt bonded geotextiles.
Shandong Hengruitong New Material Engineering Co., Ltd. has independently developed products such as geotextile, geomembrane, composite geomembrane, waterproof board, bentonite waterproof blanket, geogrid, geonet, three-dimensional composite drainage net, geocell and other products.
The production equipment is mainly imported from Germany, the United States, Italy, and Taiwan. The company has sophisticated testing instruments, advanced quality control technology and strict quality management system, and has passed the international IS9001-2000 quality system certification. Set.
Spinning clay cloth
Filament spunbond technology is one of the fastest growing processes in nonwoven technology, as is the case in geotextiles. The main process of the process is: melting the particles or powder of the polymer, then feeding the extruder into a continuous filament bundle, and randomly laying on the conveyor belt to form a web, and the geotextile in the filament geotextile is also When not fully solidified, it is pressed with a hot press roller, or bonded with an adhesive, or reinforced with a needle punch to form a continuous uniform geotextile. This method is simple in process, high in output, low in cost, and inexpensive. Since the filaments are laid into a net, such nonwoven fabrics have high strength, good elongation, and are not easily broken and torn.
Spinning clay fabrics have a number of advantages, including:
(1) The mechanical properties are excellent. Some domestic tests have shown that the tensile strength is 1.5 to 1.9 times that of the same weight-weight staple fiber needle-punched geotextile. Some foreign materials indicate that the difference is larger. In addition, the strength and creep properties such as tearing and rupture are also significantly better than short fiber needled geotextiles.
(2) The hydraulic performance is generally equivalent to the staple fiber needle-punched geotextile, and the permeability coefficient is of the same order of magnitude as that of the staple fiber needle-punched geotextile. As long as it is used properly, its permeability coefficient can be stabilized after a period of time, and the soil particles are no longer lost with water flow.
(3) The spinning speed is high, and the output of the single machine is much higher than that of the short fiber acupuncture equipment. (http://)
