Product type BF (PZ) water swelling rubber seal

First, the product type BF (PZ) water swelling rubber seal Product Description: BF product-type water swelling rubber seal products, also known as PZ-type water expansion of the seal. It is both a general rubber products performance, but also their own water expansion of new waterproof material properties. Sealing, waterproofing effect is more reliable than ordinary rubber seal. I produced the product type (PZ) water swelling rubber seal has the following characteristics:. A rubber after water will produce at least 2-5 times of expansion and deformation, and full access to all irregular surfaces Ying, a hole and clearance, while generating tremendous contact pressure, completely prevent leakage;. b When the joints or construction joints displacement, causing the gap beyond elastic range, ordinary rubber sealing material is useless, and the product can also swelling to seal. c. Use water swelling rubber seal as plugging sealing material, not only the amount of savings, but also eliminate the elastic material is generally caused due to excessive compression elastic fatigue characteristics, so that the effect is more reliable waterproof, water resistance, chemical resistance and Good anti-aging properties. d. It is mainly used now assemble shield construction method waterproof seams, building deformation joint, construction joints with waterstops and metal structures, precast concrete waterproof seams. Product type (PZ) water swelling rubber seal strip physical and mechanical properties of physics: Item Indicators PZ-150 PZ-250 PZ-400 PZ-600 1 hardness (Shore A) / of 42 ± 7 45 ± 7 48 ± 7 Tensile strength / Mpa ≥ 3.5 3 4 elongation /% ≥ 450 350 5 Tensile strength / Mpa 150 250 400 600 Elongation / 32% elongation /% 150 250 300 500 6 Flexibility at low temperature (-20 ℃ × 2h) no crack Note: hardness of recommended items. 1) Finished slice tests shall meet the standard of 80%. 2) Tensile index joints of not less than 50% Table 2 of performance. Product structure and Size: expansion project peel strength shear strength water pressure high temperature resistance, low temperature resistance performance hydrostatic proportion soak 24h100% maximum 300-500% 0.01MPa 0.06MPa 1.2MPa 150 ℃ -30 ℃ not flowing not crisp 1.5 two , putty-type BW (PN) water swelling rubber seal Product Description: BW putty-type water swelling rubber seal, also known as PN putty-type water swelling rubber seal. I produced the product is more than ten kinds of materials through mixing, kneading, squeezing water from the system of self-adhesive sealing strip of intumescent material, rectangular cross-section. Its characteristics are: to rely on its own sticky paste pre-construction joints in concrete, after pouring sewing interface. After the second pouring concrete (ie concrete wrapped state), after the product water will gradually expand, on the one hand there may be blockage of capillary pores, on the other hand to make contact with concrete interface more closely, resulting in a greater resistance to water pressure, the formation of impermeable plasticity gel, the product has a high expansion rate, mobile Supplementary strong, placed in construction joints with a strong balance after the self-healing function. Can block their own new small cracks appear due to sedimentation, for completed projects, such as the gap leakage of water, which can be used to re-seal plugging. Use the sealing of low cost and simple construction work section, the best corrosion resistance. Widely used in construction joint air defense, swimming pool, sewage treatment works, underground railways, tunnels, culverts and other concrete projects, expansion joints, cracks. Standard: GB18173.3-2002 Item Indicators PN-150 PN-220 PN-300 1 volume expansion ratio% ≥ 150 220 300 2 high heat flow is still resistance (80 ℃ × 5h) no flow still no flow and no flow 4 low-temperature test (-20 ℃ × 2h) None None rattle rattle rattle-free Size: putty-type water expansion of the seal cross-section, respectively, 15 × 20,20 × 30,20 × 50,10 × 40 (mm), and other specifications. Length can be designed according to user requirements. Mobile: 13931819338 Contact: Wan Hai Liang QQ number: 2218838017 E-mail: hongchuangxiangsu@163.com
