The ton bag is a kind of ton bag that is used for pre-stressed tensioning of the highway bridge support point and the bottom mold after it is filled with the filling master material. Its application purpose is to specify the indicators according to the new project design drawing. The value is used to control the support frame template weight to test whether the support point and template management system will be deformed due to loading. At this stage, the link is commonly used in countries around the world.
The key purpose of applying highway bridge prestressed ton bags is to detect one of the plasmid carrier packaging products, which is conducive to the professional practical operation and transportation and elimination. The advantages of using this kind of ton bags depend on the low cost of transportation and testing. Reliability and its very durable characteristics,
1. Lightweight
The packaging bags are generally lighter, and the relative density of the packaging bags is about 0.9-0.98 g/dm3. The common plastic braid, if no filler is added, is equivalent to the density of plastic. The density of plastic hand-woven using plastic is 0.9-0.91 g/cubic dm. Under normal circumstances, braids are lighter than water.
2. High elongation at break
The ton bag of plastic products in Henan Province is a kind of soft, high breaking elongation raw material. Woven bag wholesale is related to its molecular formula, crystal level, drafting tendency, etc., and also related to the type of preservative. If strength is used (Compressive strength/ratio) to consider the plastic braid, which is higher than or close to the metal composite material.
3. Good solvent corrosion resistance
Plastic woven fabric has excellent corrosion resistance to inorganic substances and organic compounds. Below 110 degrees Celsius, there is no harm to it for a very long time. It has strong organic chemical reliability against organic solvents, vegetable oils and so on. When the temperature rises, carbon tetrachloride, xylene, banana water, etc. can swell it. Fuming nitric acid, fuming sulfuric acid, halogen elements and its strong metal oxides will oxidize it in the air. It has good corrosion resistance to strong acids and general acids.
