How to use a pressure-sealing glue stick, and is it effective? A pressure-resistant leak-sealing rubber rod is composed of an elastomer and a soft outer layer. The elastomer is composed of imported graphite and high-molecular nanomaterials from DuPont in the United States; a soft surface layer made of EVA is bonded to the surface of the elastomer using adhesive. This pressure-resistant leak-sealing glue rod can withstand high temperatures; it is capable of sealing any type of medium, and offers an excellent anti-corrosion sealing effect. It is characterized in that the pressure-resistant leak-sealing rubber rod consists of an elastomer and a soft surface layer, the surface of the elastomer having the soft surface layer bonded to it using an adhesive, wherein the soft surface layer is EVA. The existing sealant rods can only withstand media at temperatures of over 400 degrees; the sealant rods made from this material have limited resistance to such media, and they exhibit significant shortcomings in terms of durability during installation as well as in providing long-term corrosion protection. Currently, research on viscoelastic products is already underway in China. However, as an anti-corrosion coating, viscoelastic adhesives have low shear strength and poor resistance to external mechanical forces. Especially in high-temperature environments, ordinary viscoelastic anti-corrosion adhesives can suffer severe damage to their protective layer due to such external mechanical forces, which affects their anti-corrosion and leak-proofing capabilities. Addressing the shortcomings of existing technologies, a pressure-resistant leak-sealing rod is provided that can withstand high temperatures, seal against any type of medium, and offers an improved anti-corrosion sealing effect. The pressure-resistant leak-sealing rod is composed of an elastomer and a soft outer layer. The elastomer is composed of imported graphite and high-molecular nanomaterials from DuPont in the United States; a soft surface layer made of EVA is bonded to the surface of the elastomer using adhesive. The pressure-resistant leak-sealing rubber rod has the following advantages: as it is made from elastic materials combined with a coating on its surface, it offers better sealing performance compared to traditional rubber sealants; it provides excellent protection against corrosion and leaks, and it can be used with any chemical medium. The classification of pressure-resistant leak-sealing adhesives can be divided into thermosetting and non-thermosetting types based on their properties under different heating conditions: (1) Seals of the thermosetting adhesive type. Thermosetting sealants acquire certain properties such as strength, elasticity, heat resistance, and resistance to various media after being exposed to a certain temperature for a specific period of time, thanks to the action of curing agents. Its curing time decreases as the temperature rises. For example, with Type B adhesive, it takes 20–30 minutes to cure at 150 degrees, while only 10 minutes is required at 300 degrees. Such sealants are composed of organic materials, inorganic materials, and additives. (2) Non-thermally curing sealant adhesives. Thermosetting sealants cannot be cured.. Sealants do not contain curing agents.. They can achieve sealing through their own properties and external forces. They are made of organic materials, inorganic materials, and resins (fats and oils), etc. The above is a brief explanation of how to use pressure-sealing glue sticks and whether they are effective.
