Aluminum formwork, also known as aluminum formwork for construction, is a new generation of formwork system after wood formwork and steel formwork, and is a great development of the construction industry. The application of aluminum formwork system in the construction industry improves the construction efficiency of housing construction projects, including saving a lot of construction materials and manpower arrangement.
The recovery of the aluminum formwork is not to remove the aluminum formwork from the construction site, but to remove concrete from the aluminum formwork. The traditional method is pickling or shot peening. Pickling does not conform to the national environmental protection policy, causing secondary pollution; Secondly, it will react violently with aluminum, easy to cause hydrogen embrittlement, affecting the service life of the template.
The shot blasting process will cause great wear on the surface of aluminum formwork, which is not conducive to the recycling of aluminum formwork. It is recommended to use aluminum formwork cleaning machine to remove concrete from aluminum formwork at present, and the cleaning effect is good.
It is inevitable that there will be some working faults in the long run of the aluminum template cleaning machine. When the pressure washer is faulty, locate the cause based on different fault symptoms and rectify the fault in time. Here we mainly introduce how the aluminum template cleaning machine is not absorbent:
Problem one, the water from the UHP washer is unstable or sometimes unstable.
1. Air is sucked into the high-pressure water pump or water inlet pipe. At this point, we just need to trigger the water cannon to reduce the working pressure of the UHP washer and run it for a period of time until a stable pressure is generated.
2. Insufficient water supply. In this case, check whether the water pressure is sufficient. Some UHP washers do not have self-priming capacity, at this time, you can add a booster pump to solve this problem.
3. Water supply filter is blocked, just clean the water supply filter.
Second, the aluminum template cleaning machine can not reach the rated pressure of the equipment
When the aluminum template cleaner is running, there is a certain working pressure, but it does not reach the rated pressure of the device, or the pressure is kept within a certain range and cannot be increased. In this case, first check whether the diameter of the high-pressure nozzle matches, if not, then match the replacement high-pressure nozzle. Next, check that the pressure regulator is in the correct position. If the pressure cannot be eliminated in these two cases, check whether the internal sealing parts of the high pressure pump (O-ring, water seal) are intact and whether the piston is damaged. If the piston is damaged, it needs to be repaired.

Determination of cleaning degree - Exhalation method
Breathe on the surface of the dry cleaning object. When the water vapor condenses on the surface, it will form turbidity fog spots. When the surface is cleaned, the fog spots are uniform. Otherwise it is not uniform. When the surface is very smooth and clean, the fog spots will disappear in a very short time.
