7. The use of polyester curtain fabric for the spherical skeleton material makes the comprehensive performance more reliable, and this process design is the first of its kind in China.

Inner rubber layer - butyl rubber, can enhance the resilience, compression permanent deformation, electrical properties, tear strength, water swelling resistance, acid, alkali, oil and other properties of rubber joints. The inner lining rubber tube layer extends to the outer end face of the rubber joint flange, and its performance is to prevent water leakage and erosion.

Skeleton layer - butyl rubber+chloroprene rubber+polyester curtain fabric; The skeleton material is selected with high strength, with a fracture strength of ≥ 190cN/tex, a fracture stress of ≥ 2.76GPa, an elastic modulus of ≥ 44N/tex, and a fracture elongation of ≥ 4% polyester cord fabric. The tight combination between the inner and outer layers and the skeleton layer is vulcanized into one, which solves the thermal expansion and overall adhesion strength and pressure resistance of the rubber joint, ensuring sufficient ability to withstand its vacuum degree and water hammer impact.

Outer rubber layer - chloroprene rubber. Chloroprene rubber is a polymer of chloroprene, which is wear-resistant, oil resistant, and aging resistant. The tensile strength is ≥ 13MPa, the elongation at break is ≥ 500%, the permanent deformation at break is ≤ 30%, the brittle temperature resistance is ≤ -30 ℃, and the adhesive strength is ≥ 2.0DN/m. Due to the exposure of the outer rubber layer of the flexible rubber joint to the air, it is easily affected and damaged by external factors, which requires the outer rubber layer of the joint to have characteristics such as heat resistance, acid and alkali resistance, oil resistance, and ozone resistance. For these situations, we used chloroprene rubber. Through a reasonable formula, the maximum operating temperature of chloroprene rubber can reach 130 ℃, and the brittle temperature is -35 ℃~55 ℃.
