- Q: What are the advantages using foil in construction?
- 1, insulation to reduce cooling costs: summer LLumar film can effectively block 79% of the sun's heat, greatly reducing the solar energy into the room, thereby reducing the cost of cooling the building. 2, thermal insulation to reduce heating costs in winter: the low-emissivity (LOW-E) film attached to the inner surface of the ordinary single glazing can reduce heat loss by 30%, reduce indoor heat loss, reduce winter heating costs. 3, blocking 99% of harmful UV rays: ultraviolet in solar radiation is mainly responsible for the damage and color fading of carpet, furniture, art paintings, curtains and many chemical fiber textile and the skin cancer. Energy-saving insulation film can block 99% of UV rays. 4, to reduce the harsh glare and add comfort: direct light at the office table or relaxing at home will lead to tiredness, eye fatigue and distraction. LLumar is a direct installation in the surface of the glazing product, it helps correct light intensity area and back positive zone temperature uneveness and dispersed glare, uncomfortable glare, making employees more comfortable interior, more efficient. 5, the formation of absolute privacy: mount LLumar reflective film may be formed absolute privacy, it can avoid the window watching, protection of private property is not exposed to activities and infringement. 6, improve safety explosion-proof performance: bonding together LLuamr armored dragon film can effectively break the glass, to reduce industrial accidents, earthquakes, typhoons, terrorism, wanton destruction, and property damage caused by theft and other acts against the people.
- Q: What are the functions of rubber diaphragm?
- The main functions of rubber diaphragm: Rubber diaphragm is mainly applied in valve, control?valve, automatic mechanical servo device, switch and counter of flux, pressure, differential, liquid level, and constant temperature thermal compensation volume. Its advantages lie in the work of high reliability, complexity, and long service life, and low cost. Under high-pressure environment, the rubber diaphragm needs to be strengthened. A reasonable selection of inside lining could be made according to the specific working conditions (pressure) and requirements. In the low-pressure jobs, the force produced by the strengthened mebrane with cloth inserted may become redundant. As for this job, the company offers homogeneous elastic rubber diaphragm made of full rubber , which can provide with the same advantages as strengthened mebrane with cloth inserted , at the same time, increase and make use of economic benefit brought by homogeneous elastic structure. Homogeneous elastic structure may be applied to a variety of rubber. Rubber diaphragm has a long service life, and it can accurately perform synchronous operations with other control components to ensure the blowing of pulse compressed air. Even if under extremely poor working conditions, it can also guarantee the normal operation and long service life.
- Q: How do geomembranes help in preventing soil erosion in coastal areas?
- Geomembranes help in preventing soil erosion in coastal areas by acting as a barrier between the soil and the surrounding water. They are impermeable and resistant to chemical and biological degradation, which prevents water from penetrating into the soil and washing it away. Additionally, geomembranes provide stability to the soil by reducing wave and tidal energy, thereby minimizing the erosive forces that cause soil erosion.
- Q: What's the function of the base membrane of wall cloth?
- Base films are basically universal for they have the same functions.
- Q: What are the considerations for geomembrane installations in areas with high soil acidity?
- When installing geomembranes in areas with high soil acidity, there are several important considerations to keep in mind. Firstly, the choice of geomembrane material is crucial. Acid-resistant materials such as high-density polyethylene (HDPE) or polyvinyl chloride (PVC) should be selected to ensure chemical resistance and prevent degradation. Secondly, proper site preparation is necessary to address any existing soil acidity issues. This may involve soil amendments or pH balancing to mitigate potential damage to the geomembrane. Lastly, regular monitoring and maintenance are essential to detect any changes in soil acidity levels over time and take necessary actions to protect the geomembrane. Overall, careful material selection, site preparation, and ongoing monitoring are key considerations for successful geomembrane installations in areas with high soil acidity.
- Q: What are the models of membrane sand paper?
- The thickness of the general model is not the same. Reference for you: Models with big thickness: 16 mesh, 24mesh, 36 mesh, 40 mesh, 50 mesh, and 60 mesh. Commonly used models: 80, 100, 120, 150, 180, 220, 280, 320, 400, 500, and 600 mesh. Models after fine grinding: 800, 1000, 1200, 1500, and 2500 mesh. Currently there is very few sandpaper with the model of 3000 mesh in domestic ! It is usually indicated by "granularity".
- Q: Characteristics of geomembrane
- Therefore, the service life period of composite geomembrane is sufficient to meet the service life period of the dam seepage-proof requirement., Ethylene / vinyl acetate copolymer (EVA), mainly including polyvinyl chloride (PVC) .hiphotos.2m added stabilizer polyethylene film, whose years of working is 30 to 40 years under sewage conditions, with small proportion, low temperature resistance, corrosion resistance, good extensibility. Composite geomembrane is a kind of soil engineering impermeable material taking plastic film as a substrate, and combined with non-woven fabrics. The service life period of geomembrane, good anti-frost?property.
- Q: What are the codes for acceptance ofreinforced concrete project construction?
- Ensure the shape, size and position of engineering structures and components in each part is correct. Have enough strength, rigidity and stability, to withstand the weight and lateral pressure of newly poured concrete, as well as load generated in the process of construction.Simple structure, convenient assembly and disassembly, convenient for reinforcing bar colligation and installation and concrete pouring and curing process. Tight template joints without spillage.
- Q: what's the paving method of composite geo-membrane?
- Geomembrane pavement is divided into channal bottom paving and slope paving two sections. pavement method: Horizontally roll along the channel axis direction. Slope pavement, after qualified acceptance of slope, rool it along the slope axis direction, the joint with the channal bottom composite geo-membrane uses t-shape connection.
- Q: How do geomembranes contribute to water treatment plant designs?
- Geomembranes contribute to water treatment plant designs by providing a reliable and efficient solution for containment and control of water and wastewater. They act as impermeable barriers, preventing the seepage of contaminants into the surrounding soil and groundwater. Additionally, geomembranes help in the separation of different treatment processes, ensuring proper containment and management of various stages within the plant. They also facilitate the storage and transportation of treated water, enhancing the overall functionality and sustainability of water treatment plants.
