Sealant products are often used in buildings, so what factors do the functional requirements for this product depend on? The nature of building sealant material requirements depend on what? Below, take a look at the content shared by Xiaobian!

    The functional requirements of building sealant mainly depend on environmental factors: including radiation aging in sunlight, oxidation of oxygen and ozone, water and water vapor erosion, the influence of environmental temperature changes, wind load, the effect of shear force, circulating machinery (compression/tensile) load, invasive air pollution (such as: Acid rain, salt spray, etc.), microorganisms and macroorganisms (fungi, etc.). After understanding the environmental factors to consider the needs of building joints, the functions of building sealant can be summarized as follows: building waterproof, sound insulation, energy saving, corrosion prevention, pollution prevention, fire prevention, decoration, structural elastic connection, structural safety and durability.

    The nature of the body depends on the chemical properties and physical structure of the sealant main polymer, is can.. Is measured repeatedly. Process property refers to the characteristics of sealant in the manufacturing process. The use of property (product performance) is self-evident mainly refers to the comprehensive performance of sealant in the formation of cementation process to the formation of cementation joint, the performance depends on the functional requirements of building joints on sealant. Whether for the outer protection of the building or building interior decoration; Whether the window structure or other forms of envelope and decorative structure, they can be regarded as unit composition, then each unit will produce joints, the vast majority of the need for building sealant to seal and fill. Reasonable design of building joint, understanding of building sealant, reasonable material selection and correct construction of building seal is essential to the success of the whole process of building joint seal.
