The roll packaging tape can be protected by wrapping it on the surface of the substrate. Because semi-solid polymers have better water resistance, this protection method can provide reliable corrosion protection. However, if the flange shape is complex, the material is not only time-consuming, but also difficult to construct.

4. Hot melt plastic solution

Hot melt adhesive is essentially a wax like fusible polymer heated at high temperature and sprayed on the surface of the substrate by professional hot melt equipment. The advantage of this protection method is that it can be remelted and reused, thereby saving costs. Although this method can be reused, it also requires thermal work, professional equipment and building services. Although it can be reused, it is not easy to open and seal during maintenance.



5. Polymer sealing bag solution

he sealing bag can completely cover the flange, and its composition is composed of low permeability polymer, corrosion inhibitor steam and desiccant, which is easy to install. However, the end of the bag is only sealed with tape, not a durable and effective mechanical combination. There is a large area of steam space in the bag, which tends to accumulate a large amount of water and consume corrosion inhibitors for a period of time.
