Chloride is a common inorganic anion in water and wastewater. Chloride ions are found in almost all natural water,and their levels vary widely. In rivers, lakes. In marshes, chloride levels are generally low,but in seawater,salt lakes,and some groundwater levels can be as high as tens of grams per liter. In the human survival activities,chloride has very important physiological functions and industrial uses.Because of this,a considerable amount of chloride ions are contained in domestic sewage and industrial wastewater.
If the content of chloride ion in the book reaches 250mg without litres,the corresponding cation is sodium,will feel salty; High levels of chloride in water can damage metal pipes and buildings and hinder plant growth.

1. When performing the tensile test, the sample fracture is always broken on both sides.
2. The pointer of the dial is poorly sensitive, the position of the pendulum is not normal, and the pendulum of the impact tester is not allowed to be vertically marked.
3. The hammer return is not normal, and it is fast and slow. The passive needle does not stop well at any position and does not coincide with the main needle.
4. When loading, the oil system is seriously leaking or the tubing is broken.
5. After the sample breaks, the pendulum quickly falls back, causing an impact.
Under normal circumstances, the solution to the impact test machine failure is:
1. When the jaws are not clamped, the specimens should be clamped symmetrically as required.
2. The quality of the jaws is inferior and the teeth are damaged. In addition to affecting the different cores of the jaws, the specimens are slipped during the test, making the yield point difficult to identify. The jaws should be replaced at this time.
3. The adjustment of the lifting guide wheel is not correct, so that the upper and lower jaws are not concentric. A test rod shall be machined, and the upper and lower jaws shall be tensioned and measured with a dial gauge based on the two force columns until the adjustment is passed. Replace the oil with the right viscosity. Check if the joint of the oil circuit system is tightened. If it is necessary to replace the gasket, replace it in time. If the tubing is broken, check if the joint of the oil system is tightened. If it is necessary to replace the gasket, replace it in time. If the tubing is broken, it is necessary to replace the tubing with higher strength. In addition, observe the oil delivery valve and whether the relief valve piston is dead or reversed.
