Features of water expandable waterstop First of all, the water expandable waterstop has high expansion ratio and strong moving supplement ability, which can effectively balance the self-healing function and ensure the waterproof effect of the project. Secondly, the waterstop is easy to construct, cheap, harmless and pure, can be immersed for a long time without precipitation of dissolved substances, and has high corrosion resistance, which can be widely used in various projects requiring waterproofing. In addition, compared with other hydrophilic expansive waterstops, the hydrophilic expansibility of the waterstop is not lost after long-term repeated expansion, which can better achieve the waterproof effect.

The reinforced mesh putty type water swelling waterstop has more superior characteristics and advantages than Puzhaotong rubber. This kind of rubber will produce 2-3 times of expansion deformation after encountering water, and fill all irregular surfaces, cavities and gaps of the joints. At the same time, it will generate huge contact pressure to completely prevent leakage. When the joint or construction joint is displaced, causing the gap to exceed the elastic range of the material, the ordinary rubber water stop material will lose its water stop function. The material can also stop water by absorbing water and expanding. The use of water swelling rubber as a leak stopping and sealing material can not only save the consumption, but also eliminate the excessive compression of general elastic materials

Our common product types of water swelling waterstop are mostly rectangular and red. There are two main production processes, extrusion type and vulcanization type. The expansion rate of product type water swelling waterstop can be divided into four types: PZ150 PZ250、PZ400、PZ600。 The performance characteristics of extruded waterstop and vulcanized waterstop are different. In practical application, we should select suitable waterstop products with water expansion in accordance with construction requirements. The expansion rate of extruded product type water expandable waterstop is 250%~600%, but the tensile strength is small, generally 2.5~2.6MPa

The price of medium buried steel edge rubber waterstop is affected by many factors, such as specification, model, width, thickness, etc. The price span is also relatively large. Normally, the more rubber is used, the more complex the process is, the higher the price is. How much is the price of medium buried steel edge rubber waterstop? If you want to know the price of steel edge rubber waterstop, first determine the specific specifications, such as width and thickness. The width is 300mm, 350mm, 400mm, and the thickness is mainly divided into 8mm and 10mm. Basis for selection of rubber waterstop with steel edge in the middle buried pipeline: this problem will be solved by selecting rubber waterstop with steel edge, because the adhesion between galvanized steel plate and concrete is good

External sticking waterstop is called back sticking waterstop, back sticking rubber waterstop and external sticking rubber waterstop. There are various specifications of the bottom plate externally attached waterstop, which can also be processed according to the customer's samples. Although the application of the bottom plate externally attached waterstop is not as extensive as that of the mid buried waterstop, it is gradually being valued with the strict requirements for the project quality. The external sticking waterstop of the bottom plate can be divided into external sticking rubber waterstop and external sticking plastic waterstop according to the material, and can be divided into the non hole type external sticking waterstop in the middle of EP and the hole type external sticking waterstop in the middle of EB according to the construction position. In tunnel construction, rubber is the main material, but this industry has developed

Introduction to waterproof materials for expansion joints: since the waterproofing of expansion joints in the project will leak due to various factors, it is necessary to use water swelling waterstop, two-component polyurethane sealant, steel edge rubber waterstop and other materials for repair. The following waterproof materials are briefly introduced: the water swelling waterstop is a kind of elastic joint waterstop material, and the water swelling waterstop has rubber properties, water resistance, acid resistance, and alkali resistance. The role of the water swelling waterstop is that when the distance between the two sides of the joint is increased beyond the elastic recovery rate of the elastic waterproof material, The water swelling waterstop has the characteristics of water swelling

Use of closed cell foam board 1. Closed cell foam board is widely used in the construction field, which can be used for heat insulation and heat preservation of roof, wall, ground and other parts, as well as waterproof in wet environments such as basements and swimming pools. Closed cell foam board has good heat insulation performance, which can effectively reduce the energy consumption of buildings and improve the energy-saving effect. At the same time, closed cell foam board also has good water resistance and moisture-proof performance, which can effectively prevent buildings from moisture, mildew and other problems. 2、 The closed cell foam board in the industrial field is also widely used in the industrial field, often used to make sound insulation, shock proof, thermal insulation and other materials, such as industrial plants, refrigeration

Rubber waterstop is a common building material, which is used to prevent water or other liquids from leaking from the joints of buildings. It is usually used in underground works, roofs, walls, windows and other building parts to provide an effective sealing effect. The main function of rubber waterstop is to form a reliable barrier at the joints of buildings to prevent water or other liquids from penetrating. It is usually made of rubber material, with high elasticity and durability, and can adapt to the thermal expansion and contraction of buildings due to temperature changes. The principle of rubber waterstop mainly includes two ways: physical barrier and chemical reaction. Physical barrier refers to rubber waterstop
