- Q:How do geomembranes handle ground freezing?
- Geomembranes are engineered to handle ground freezing by their ability to withstand extreme temperatures and maintain their structural integrity. They are made of flexible materials that can expand and contract without cracking or tearing. Additionally, certain types of geomembranes are designed with insulation properties to minimize the transfer of heat between the ground and the surrounding environment, helping to prevent freezing of the underlying soil. Overall, geomembranes provide a reliable barrier against ground freezing and play a crucial role in various construction and environmental applications.
- Q:Is PVC preservative film toxic?
- PE film is a substitute for PVC preservative film which is non-toxic. Carcinogenic PVC preservative film: most of preservative films in the market in China which is made of PVC, and the prevalent saying that preservative film is toxic means there is a possibility that some of the harmful materials cause cancer when released. so, is PVC preservative film really toxic? It is said that once the PVC preservative film contacts the oil in cooked food, the harmful matter will be easy to be released. It will affect people's internal secretion, even cause breast cancer, birth defects of new-born babies or fertility problem of men. Europe and the United States, Japan and South Korea prohibited the use of PVC preservative film PVC at least 5 years ago, but the eliminated technology was introduced to China. There are joint ventures and exclusively foreign-owned enterprises produce using the technology, of which three major brands are LG, Mitsubishi and Sanrong whose output accounted for 70% of the entire market. Domestic preservative film companies started late, so the technology is relatively new, and they all use PE to replace PVC, but the market share of only 30%. : To identify whether the preservative film is toxic, the method is very simple. Light the preservative film with a lighter, if it drop like wax after burning and emit a smell of candles, then that is non-toxic polyethylene film. PVC has an unpleasant pungent smell.
- Q:How do geomembranes contribute to water storage reservoirs?
- Geomembranes contribute to water storage reservoirs by providing a reliable and impermeable barrier that prevents water seepage and leakage. They help to maintain the water level and quality by minimizing evaporation, contamination, and infiltration. Additionally, geomembranes ensure the structural integrity of the reservoirs by reducing the risk of soil erosion and maintaining the stability of the embankments. Overall, geomembranes play a crucial role in enhancing the efficiency, reliability, and sustainability of water storage reservoirs.

- It is good and more environmental friendly! And have a good quality
- Q:What are the technical points of the lioghtweight foam?concrete?
- 1. To clean the surface and ensure that there is no dust and dirt of the grassroots, for smooth, solid, light pressure, does not allow rugged, loose and sand off ash and other defects. 2. To make a good preparation of the materials, the foaming agent, additives, cement and auxiliary materials should be transported to the designated place for storage. 3. It should be leveled according to the design. First, take use of the cement mortar according to 2.5x2.5m to determine the height of the slope. 4. To start the foaming machine to start to work, and then start the host. To sent the cement into the agitator with the help of the conveyor?belt/band carrier. And after it is mixed uniform to start the transportation system of foam conveying system and high-pressure pump. And then mix the concrete composite material averagely and transport them to the disignated construction area to cast. 5. According to the requirements of the construction, the professionals will smooth the castin foam concrete. (with help of the smooth floating ruler) Because after it is being smooth, the surface of the foam cement will produce a little air void which will have a bad effect of the surface of the waterproof construction. It is suggested to establish the 70% final set of the casting foam concrete and use the cement mortar to smooth and protect. 6. When the integral casting of foam concrete has reached 4000 square meters and the final set of the concrete has up to 70%( It is generally 25 centigrade and 36 hours). The cut of the dividing joint should be in time. And the width of the dividing joint should be bigger than 4x4m. The the width and depth of cutting of every dividing joint should be calculated by 1/800 telescopic value of the thermal efficiency expansion. The deepth of the width of cutting is 1.5x3.0cm, the elastic sealing material will be sealed in after the cutting.
- Q:How long is the service life of electrothermal?film?
- The service life of electrothermal?film has a certain relationship with the quality itself. Now there are many domestic and Korean electrothermal?film in the market, the general warranty of which is about two years, American electrothermal?film is better. The heating system of electrothermal?film is sealed with special printing ink in the interlayer of macromolecular polyester films which can burn-in under constant high temperature condition. The surface normal working temperature of American electrothermal?film is around 40 degrees which is far below the burn-in temperature, therefore its service life is the same as that of buildings.
- Q:What are the specifications of PE winding film?
- Winding films are generally customized according to the requirements of customers, and the weight of the inside core is also put according to customers' requirements, usually weighted 10-15 per kg. As for the weight of winding film, some sellers take the weight of the inside core into account, some sellers don't. So when buying you have to figure out whether the core weight is removed.
- Q:What is the installation technology of soft membrane?
- When installing the soft membrane, the first is to install the four angles of A, B, C, D, then the diagonal pull point installation, finally all installation. The installation sequence: 1. Before the entering of the soft film smallpox, the site must be electrified and without construction waste. 2. The deal with the bottom of the piamater ceiling should be fit for the installation conditions, such as the installation of the steel and so on; it must be cleaned. 3. All the installation of the lights must be according to the requirement of us. We should ensure all of the circuit to be electrified. If there are any lamp not lighting up before installing the soft film, it should be adjusted and repaced in time. The interior hidden lights should be painted with white paints so as to get a better effect. 4. The air conditioning and fire pipes must be arranged in advance and debug to keep it operating well. After the installation of the air inlet, spray head, and smoke sensor, all of them should meet the requirements of us. 5. After the installation of the piamater ceiling is completed, for example, the paint should repair the gypsum board and should not touch the soft film smallpox.
- Q:What are the considerations for geomembrane selection in hydraulic structures?
- When selecting a geomembrane for hydraulic structures, several important considerations need to be taken into account. Firstly, the geomembrane material must have a high level of impermeability to effectively prevent water leakage. It should also have good resistance to chemical degradation and be able to withstand the specific environmental conditions of the hydraulic structure. Additionally, the geomembrane should have sufficient strength and durability to resist punctures, tears, and other mechanical stresses. Other factors to consider include UV resistance, flexibility, ease of installation, and cost-effectiveness. Ultimately, the selection of a suitable geomembrane should be based on a thorough understanding of the specific requirements and conditions of the hydraulic structure.
