? Water swelling rubber water stop water swelling rubber water stop Introduction water swelling rubber water-stop in addition to a general rubber water-stop performance, its main feature is the use of a special waterproof line has water expansion project rubber. Thus, after expanding rubber water swelling water stop and enhances the tightness of structures, waterproof, better sealing effect. Water swelling rubber water-stop expansion of water line portion sizing execution GB18173.3-2002 standards. The rest of the rubber and general physical and mechanical properties of the same rubber water stop, do GB18173.2-2000 standards. Water swelling rubber physical properties of the line (Executive Standard GB / T18173.3-2002) PZ-150 PZ-150 PZ-400 PZ-600 1 hardness (Shore A) / degrees 42 ± 7 45 ± 7 48 ± 7 2 Tensile strength / Mpa ≥ 3.5 3 3 snapped a long stretch rate /% ≥ 450 350 4 volume expansion ratio% ≥ 150 250 400 600 5 repeated immersion test the tensile strength / MPa ≥ Elongation at break /% ≥ volume expansion ratio /% ≥ 3 2 350 250 150 250 300 500 6 low bending (-20 ℃ × 2h) crack-free water swelling rubber water stop: 1, HJ-L structure series waterproof line water stop can be made into the water swelling rubber water stop, as shown: 2, in order to make the water stop sections force uniform, reasonable, our Technical Department designed the HJ-A series water swelling rubber water stop, its cross-section using a non-uniform thickness structure, divided into a strong area, water area and the mounting area while stretching the hole wall is flat, when the template folder system, a large contact surface, waterproof dislocation, in addition of the mounting hole mounting area, can make it with relative o tendons easy fixed, not displacement, easy construction and installation.
