Bridge preloaded ton bags, also known as bridge preloaded container bags. It is a container bag used for pre-loading after the bridge and bottom mold are filled with filling material. Its purpose is to be able to control the precipitation of the bracket template according to the actual requirements of the engineering design drawings, and whether the bracket and template system are deformed due to load is widely used at home and abroad.
The main purpose of using the bridge preloaded ton bag is to test a carrier packaging material that is easy for mechanical handling, handling and disassembly. The advantages of using this ton bag are low transport and test costs, strong reliability and considerable durability.
1. Greatly save the time to buy stuffing; 2. Easy to transport and disassemble after use; Container manufacturers believe that the bridge packing ton bag will become the ideal choice of packaging materials for bridge packing projects.
Step 1 Be light
Commonly used plastic woven fabrics, if no filler is added, are equal to the density of plastic. For plastic braiding applications, the density of plastic is 0.9-0.91 g/cm3. Usually, woven fabric is lighter than water.
2. High breaking strength
The wholesale of woven bags is related to its molecular structure, crystallinity, drafting direction, etc., and the type of additives. If the specific strength (using strength)/specific gravity) is used to measure the plastic braid, the material of the braid is higher than or close to the metal material.
3. Good chemical resistance
Plastic braided fabric has good corrosion resistance to inorganic and organic matter, less than 110 degrees Celsius, no long-term impact on plastic braided fabric, and has strong chemical stability to solvents, fats and so on. When the temperature rises, carbon tetrachloride, xylene, turpentine, etc., may swell. Fuming nitric acid, fuming sulfuric acid, halogen elements and other strong oxides oxidize it. It has good corrosion resistance to strong alkalis and common acids.
