Q:What's the principle of diaphragm valve?
Principle of diaphragm valve: Diaphragm valve is a special form of block valve, appearing in the 1920s. Its opening and closing member is a separator made of a soft material, to seperate inner cavity of valve body and inner cavity of bonnet, so it is called as diaphragm valve. Features of diaphragm valve: The most prominent feature is to seperate inner cavity of lower valve body and inner cavity of upper bonnet so as to protect valve rod, valve clack and other parts above diaphragm from etching by medium. It save filler sealing structure, and medium will not leak. diaphragm made of rubber, plastic membrane and other soft sealing material has good sealing property. Because diaphragm is a wearing part, it should be replaced at regular intervals depending on the medium characteristics. Due to limitation of diaphragm material, diaphragm valve is suitable for low pressure and medium temperature. Diaphragm, according to structure, can be divided into: house, straight-flow, cut-off, straight-through, flashboard and right angle types. The connection form is usually flanged joint. According to drive mode, it can be divided into manual, electric and pneumatic types, among which pneumatic drive is divided into normally open , normally closed and reciprocating types.
Q:The physical properties of HDPE geomembrane
It has the following physical properties: ① excellent chemical resistance (corrosion resistance); ② outstanding resistance to stress cracking (ESCR); ③ the lowest permeability; ④ excellent UV resistance; ⑤ stable resistance to low temperature embrittlement;
Q:What materials does geomembrane belong to?
The geomembrane is a kind of geosynthetics, including the geotextile, geogrid, geogrid, and so on. The geosynthetics is made of polyethylene, polypropylene, polyester and other plastic materials. The main function of the geotechnical membrane is seepage-proof, that is to say, preventing water from penetrating through. The most important material is polyethylene, other types are less in the total number, including PVC, EVA, EPDM.
Q:welding specifications of composite geo-membrane.
①lap joint: lap joint width shold be 15cm; ② hot welding: Suitable for thicker geomembrane weld lap width of the substrate to 5CM. (Recommended bonding, soak the glue in water, poor seepage-proof effect.) digging the base into protective layer of mortar in the bottom of the lake(H20-30mm), slope cutting, dense and smooth composite geomembrane and vertical bulkhead, smooth pasted base surface, clear, step transfer of water pipe mouth sealed with sealing geomembrane laying welding and repair welding procedure handover quality acceptance, completion and acceptance of a high-level design: About 0.6m 2, waterproof construction total area is about 800㎡ 3,ceramsite brick built bulkhead, 4, collapse pit set by water
Q:Is the geomembrane bag made of geomembrane or geotextile?
The two layers of geomembrane bag are made of geofabric not geomembrane or geotextile, mainly used for the watercourse before the revetment (environment friendly geomembrane bag).
Q:How do geomembranes prevent further contamination in site remediation?
Geomembranes prevent further contamination in site remediation by acting as a barrier between the contaminated soil or water and the surrounding environment. They are impermeable liners made of synthetic materials that are installed to prevent the migration of contaminants. By isolating and containing the contaminants, geomembranes help to prevent their spread and protect the surrounding soil, groundwater, and surface water from further contamination.
Q:What are the characteristics of the ceramic film?
Ceramic film has a lot of features , specifically the following points. First of all, the source of it's raw materials is very wide, and the price is more affordable, compared with ultrafiltration and reverse osmosis membrane, it has its own advantages. Secondly, it has a very high mechanical strength, and it will not be deformed under high pressure, in particular, to facilitate the higher pressure recoil, can be stable. It is high temperature resistant, it will be stable under the condition of belowing the temperature of thousands of degrees , the third, its chemical properties can effectively anti microbial, for those corrosive gases have very high endurance. What it shows us is good stability, we can use strong acid to clean it.
Q:Are geomembranes resistant to UV radiation?
Yes, geomembranes are generally resistant to UV radiation. They are designed to have high UV resistance in order to withstand prolonged exposure to sunlight without significant degradation or damage.
Q:What are the differences between the geomembrane and the anti-seepage film?
Geomembrane is actually the same product as impermeable membrane, but the name is different. Due to seepage prevention effect of impermeable membrane , it is slowly called impermeable membrane by some people.
