The various rubber waterstops produced by our factory include dozens of models and hundreds of specifications. It is widely used in underground concrete expansion joints in sewage treatment plants, water plants, dams, hydropower stations and so on. All products are produced using the national standard GB18173.2-2000 standard organization, and the dimensional tolerances will be implemented according to national standards. If the user has special requirements, they can be manufactured according to user requirements.
The externally attached waterstop models are classified and numbered by categories to facilitate design reference and user ordering. It can produce rubber waterstops of various shapes and sizes according to user requirements. In addition, cross-shaped, T-shaped, inclined and internal and external corner products are available for different projects and different parts, which can be applied to any design requirements. . When transporting the externally attached rubber waterstop, avoid direct sunlight and avoid contact with heat sources, oils, and harmful solvents. The finished product should be laid straight and flat without any pressure. The storage place should keep -10- + 30, relative humidity 40% -80%.
Externally attached rubber waterstops, mid-buried rubber waterstops and steel-edge rubber waterstops are the main products of our company. Our company has been engaged in waterstop products for nearly 20 years, and the qualified rate of the products sold is 100%. The externally attached rubber waterstop is made of elastic materials, mixed with various auxiliary additives, and is made by mixing and vulcanization.
Externally attached waterstops are classified according to the location in the concrete, also known as back-attached waterstops, used to prevent water in concrete expansion joints. The back-attached waterstop can be processed according to raw materials. It can process natural rubber back-attached waterstop, and EPDM back-attached waterstop. According to the shape, it can be divided into EB type (back-attached middle water-stop tape) and EP (back-attached middle water-stop tape).
The externally attached waterstop is widely used as an important type of rubber waterstop. The principle of water sealing is to use the dense bite between the rack protruding on the surface of the back-attached water stop belt and the molded concrete to seal the water. The surface of the grouting pipe and the grouting hole are used to fill the slurry evenly in the gap between the water stop belt rack and the concrete to achieve the purpose of sealing the water. The grouting liquid can be cement slurry or chemical slurry. The back-attached waterstop also serves as a waterproof enclosed area in the tunnel.

Use the cleaning device to clean the system online. The steps are as follows:
1. The system is cleaned by reverse osmosis demineralized water for 3-5 minutes;
2. Check the cleaning tank, hose and precision filter and install a new filter if necessary.
3. Calculate the amount of cleaning drugs according to the system and membrane arrangement.
4. Inject the reverse osmosis water or demineralized water into the cleaning tank to the appropriate amount.
5. Slowly add the calculated dosing amount.
6. Adjust the pH of the solution to 2.0 using ammonia (NH3) or Hyde Energy HY-430.
7. Circulate and wash for 30 minutes under water pressure of 0.1Mpa (soaking effect will be better after soaking for 30 minutes); the cleaning flow rate should be recommended by the membrane manufacturer or system supplier.
8. If the pollution is serious, please drain the first return water (up to 15% by volume) to prevent redeposition of the pollutants.
9. If the cleaning solution becomes cloudy or the pH value exceeds the specified range, it is necessary to reconstitute the cleaning solution;
10. During the cleaning process, the pollutants will consume the cleaning chemicals, the PH value will change accordingly, and the cleaning ability of the medicine will be reduced. Therefore, it is necessary to monitor the change of pH value at any time and adjust the PH value in time.
11. Soak the membrane element in the cleaning solution, which is a very effective way to dissolve metal dirt. It is recommended to repeatedly soak and alternate the circulation of the water.
12. For multi-stage systems, each section should be cleaned separately for maximum effect.
13. Before the system is cleaned and re-commissioned, flush the system with low pressure until no more cleaning liquid remains in the system.
