Key items for UV cured CIPP operation and construction:
Inner layer breakage
The inner layer of the UV curing repair material is a plastic film, which is easy to be damaged due to improper operation during construction
Once it is scraped, the materials in this section are basically discarded, and there are basically no rescue measures. Therefore, protecting the inner membrane of materials during construction is the key and difficult point of construction.
The dragging and curing operation of materials is also very important in construction. Here, the causes of inner membrane damage are summarized to ensure the actual construction
It does not occur during work.
Binding head
To bind the binding head, first check whether the binding head has any damage or burr, whether it is clean, and whether there is any sharp thorn formed after resin curing, in case of any of the above conditions, the burr must be cleaned, the burr must be ground flat, and multi-layer winding film must be wound to protect the binding head from pollution, which also serves to isolate the binding head from the inner membrane of the material, so as to protect the inner membrane from being damaged by sharp burr. In particular, the keel must be wound for several more circles.
Handle the binding head with care. If the binding head hits the inner membrane of the material, it is easy to bump the inner membrane of the material.
When binding the head, more materials must be bound and bound firmly to ensure that the head will not jump out during pressure.
Being jumped out may cause damage to the inner membrane, which is unfavorable for the smooth construction. In serious cases, it may cause construction failure and threaten personal safety. Although it is possible to rebind the head, the secondary binding head is difficult to operate and is not easy to bind firmly. Especially DN800 and above materials.
