Filament geotextile roll spread with artificial; cloth to be smooth and proper deformed left margin. Filament geotextile devices usually lap, sewing and welding several ways. Width ordinary stapling and welding is 0.1m or more, or more lap width common to 0.2M. Possible long-term exposure of geotextile should be welded or stitched. Everything suture filament geotextile will need continuous suture stop (for example, point seam is not allowed). Before stacking practical non-woven geotextile, geotextiles essential stacked least 150mm. The minimum interval selvage stitches (data exposed edges) is at least 25mm. Geotextile sewn seams feasible and most include a line-shaped locking chain stitch. For suture line should go beyond the resin material 60N for minimum tension, and with equal or exceed the geotextile resistant to chemical corrosion and UV resistance. On any sewn geotextiles "drain pin" must be in the center was re-stitched impact. Necessary to take appropriate measures to prevent the rear devices, soil, particulate matter or foreign substances into the geotextile layer. Cloth according to the terrain and use overlapping functions can be divided into natural lap, stitched or welded. Filament geotextile in construction, the above geotextile geomembrane natural lap, upper geotextile geomembrane seam welding or hot air. Hot air welding is the first filament geotextile convergence approach, namely instant high heat with a hot air gun on the convergence of two pieces of cloth to the local reach molten state, and immediately make use of certain external forces firmly bonded together . Under wet (rain and snow) can not stop the hot sticky weather conditions converge nonwoven geotextile manufacturers, geotextile should take another approach to the convergence of a suture method, which uses a dedicated machine stops double stitched convergence of quality non-woven geotextile, and the use of anti-chemical UV sutures. Suture minimum width 10cm non-woven geotextile, naturally overlap when the minimum width is 20cm, when the hot air welding minimum width 20cm. Filament geotextile stitched on to the same quality and geotextile sutures, sutures to be used to destroy chemical resistance and UV mapping to a stronger material. Preparation and adsorption properties of bentonite waterproof blanket on us are not familiar with, we understand that our country has proven reserves of bentonite in the world, but less direct practical application, which is due to natural factors bentonite by itself limit, the adsorption capacity can not meet the requirements for pollution control. After the modified bentonite can be made of the good performance absorbent material, and has played an important role in environmental pollution control, and therefore the development of its in-depth study of the higher economic and social benefits. In this study, cetyl trimethyl ammonium bromide (CTMAB) and quaternary chitosan (HACC) to collaborate on sodium bentonite modified, preparation of new adsorbent material, depending on the adsorption object, investigated the best Preparation of organic bentonite, which is used for wastewater treatment. The effects of Modified Bentonite single organic pollutants aniline, phenol and aniline complex pollutant Cd2 +, and Cd2 + phenol main factors to analyze its adsorption properties. GCL experts concluded that the relevant law: adsorbent dosage 4.0g are better; have a strong adsorption of pollutants within the range of composite bentonite modified in a wide pH (3-9) bentonite organic layer adsorption of aniline, phenol, can quickly reach adsorption equilibrium, Cd2 + 40min when arriving at the adsorption equilibrium and adsorption processes follow a quasi-second-order kinetic model;; the presence of Cd2 + adsorption rate of aniline, phenol rate no effect, but aniline presence of phenol to Cd2 + adsorption promoted; organic bentonite Under the experimental conditions of organic matter and heavy metal adsorption principle is different from the adsorption of aniline, phenol, mainly through a distribution function to achieve, while the Cd2 + adsorption is accomplished primarily through chelation.
