The two-component polysulfide sealant has the performance of self bonding with concrete, has the ability of caulking and water stop, and can contact with water 48 hours later. It is widely used in underground waterproof joints, aircraft runways, water storage facilities, sewage pools, underground projects, large water conservancy projects, etc. Features of two-component polysulfide sealant include:? Oil and solvent resistance?: As polysulfide sealant contains very strong polar "-- SS --" group, it is difficult for gas to diffuse into it, showing good gas tightness. At the same time, the existence of this group also makes polysulfide sealant not combine with oil, non-polar solvents, etc., so it has

The groutable rubber waterstop is a new type of waterstop, which is improved on the basis of the traditional waterstop. By setting grouting pipes and check valves on both sides of the waterstop, the waterproof safety coefficient of the construction/expansion joint is improved.? This waterstop is designed to solve the weakness of traditional waterstop, especially in the construction process of deformation joints and construction joints of waterstop with good waterproof performance. If the construction quality is not up to standard, water can still seep from the gap between waterstop and concrete, causing water leakage. In addition, poor joint quality of waterstop is also the main reason for water leakage of construction joints.? The main part of groutable rubber waterstop

PZ type rubber waterstop is a type of waterstop that expands when encountering water. There are two production processes for this product type waterstop. One production process is continuous extrusion through an extruder at high temperature and high pressure, with fast production speed. It is characterized by high expansion rate, higher tensile strength than bw type waterstop, and moderate hardness. In the other production process, the vulcanizer is used for high-temperature vulcanization molding production, and the production speed is relatively slow, but the tensile strength is higher than that of the extruded waterstop. Water expandable waterstop is mainly divided into the following categories: I. BF (PZ) product type water expandable waterstop: this waterstop is mainly red, with high expansion rate and good elasticity

? Type 652 rubber waterstop is a medium buried rubber waterstop. Its design features include a hole in the middle and two ridges on both sides. This structure helps to improve the waterstop effect.? It is mainly used in various concrete structures, such as water retaining dams, reservoirs, subways, culverts, tunnels and other underground projects, to prevent water seepage problems caused by foundation deformation, concrete cannot be poured continuously or thermal expansion and contraction. The raw materials of 652 rubber waterstop include natural rubber and various synthetic rubbers, which are made by adding various accelerators through the processes of plasticating, mixing, vulcanizing, molding, etc. Common specifications are 280 × 6

? LNR dispersion isolation rubber bearing? It is a new type of plate rubber bearing with excellent performance. It uses the working principle of "horizontal force dispersion" for reference, and greatly improves and innovates the conventional laminated rubber bearing. This kind of bearing can meet large shear displacement, ensure that the upper structure of the bridge effectively transmits force to the lower structure, and realize the horizontal force dispersion of the lower structure of the bridge, and each pier cooperatively resists the horizontal force. It is applicable to the requirements of large shear displacement under the action of temperature change, earthquake, etc., and the bearing has good integrity. LNR decentralized isolation rubber bearings can be divided into LNR (G) fixed type and LNR (H) sliding type according to the structural form

? LRB lead core isolation rubber bearing? It is a kind of bearing used for isolation structure. It is formed by pressing lead core into the center of RB bearing, forming an isolation device with good plastic deformation capacity and energy absorption capacity. The bearing is composed of a stable restoring device of rubber bearing and an energy absorption device of lead, forming an isolation device with an integrated damping mechanism. The design inspiration of lead rubber bearing comes from the excellent mechanical properties of lead, including its good plastic deformation capacity and energy absorption capacity, which makes it widely used in engineering. The characteristics of LRB lead core isolation rubber bearing include:

Expansive rubber waterstop is a new type of waterproof material with water swelling performance, which is mainly used for waterproof sealing in construction engineering, underground engineering and other fields. The following is a detailed introduction to it: water swelling performance: this is the most critical feature of the expansion rubber waterstop. Its main components usually include super absorbent resin, rubber matrix and various additives. When the waterstop is in contact with water, the super absorbent resin will quickly absorb water and expand, and the volume can be increased several times or even dozens of times. For example, the volume expansion rate of some high-quality expansion rubber waterstops can reach 200% within 24 hours after encountering water

? The circular plate rubber bearing has four functions: compression function, shear function, rotation function and sliding function.?? Compression function?: The circular plate rubber bearing can support the vertical load generated by the dead load and live load of the bridge, has sufficient vertical stiffness, and can reliably transfer the upper structural pressure to the pier.? Cut function?: Adapt to temperature changes. When the bridge length changes due to concrete shrinkage and creep, the circular plate rubber bearing has a certain shear deformation capacity and meets the horizontal displacement capacity generated by the superstructure, and does not transfer excessive horizontal load to the pier.? Rotation function?:

? Two component polysulfide sealant is an elastic sealing material composed of two components. Its main components include liquid polysulfide rubber as the main agent, and metal oxide or other chemicals as the curing agent.? This sealant has excellent elasticity, heat resistance, cold resistance, aging resistance, oil resistance, solvent resistance and other properties, especially its air tightness is very good, and it will not combine with oil, non-polar solvents and so on, showing good oil resistance.
