Glue Sealing Rubber HEC750-2 is a high-performance flat sealant mainly used for sealing various flat surfaces such as end caps, flanges, and coolers of steam turbine generators. This product is made of single component synthetic rubber and is free of dust, metal particles, and other impurities, making it widely used in steam turbine generator sets. At present, this sealant is used in domestic units including 1000MW units, 600MW units, 300MW units, etc.

The characteristic of Glue Sealing Rubber HEC750-2 is that when used in combination with trench sealant, it can achieve the sealing effect of gap sealing, especially on some aging and low-quality sealing gaskets; it can achieve penetration sealing and rapid shape sealing. During unit maintenance, the residue of the sealant is also easy to clean, providing convenience for maintenance work.

When using Glue Sealing Rubber HEC750-2, it is necessary to pay attention to its correct usage method. For example, during the assembly process of the generator hydrogen cooler, the sealing gasket between the cooler and the cooler cover needs to be evenly coated with a layer of 750-2 type sealant on both sides during installation to ensure the sealing effect. The appearance of this sealant is a light yellow paste like liquid, with a viscosity between 25-40 P and a sealing performance exceeding 1MPa, which can meet the sealing requirements of high-capacity hydrogen cooled steam turbine generators.

In addition, to ensure the performance and shelf life of Glue Sealing Rubber HEC750-2, storage conditions are also important aspects that need to be noted. Sealant should be placed in a dark, dry, and well ventilated warehouse for sealed storage, avoiding proximity to heat sources and exposure to sunlight, and preventing compression. The storage period of HEC750-2 sealant is 24 months at room temperature (2-10 ℃).

The application of Glue Sealing Rubber HEC750-2 in steam turbine generator units is crucial. It not only provides excellent sealing performance, but also facilitates cleaning during unit maintenance. The correct usage and storage conditions are crucial for maintaining its performance and extending its shelf life. Through reasonable use and maintenance, HEC750-2 sealant can ensure the normal operation and safety of the steam turbine generator set.
