- Q:How to deal with the situation when the drilling equipment punches holes on the composite geo-membrane of dam?
- The hole punched can be repaired by sweat soldering with geomembrane that is the same with the repaired one. After that, the concrete is required to fixedly seal the hole.
- Q:what is the specs of geomembrane used in landfill?
- It mainly depends on the thickness of the film. thickness of HDPE geomembrane ranges from 8mm to 3mm. national standards T17643-2011GB & # 47,0
- Q:Is silicon crystal electrothermal film heater good?
- It has heating speed, not dry, but the speed is slower than ordinary electrothermal film. The biggest advantages of silicon crystal electric heating plate or tube is that infrared ray radiation is stronger than heating wire and electric heating quartz tube, so it has rapid heating rate without any pollution. On the market, however, there are silicon plates that are heated indirectly by heating wire instead of electrifing, which are similar to electrical heating quartz tube. The main drawback of silicon crystal heating plate is that the electrifying port is prone to oxidize, causing poor contact. It is more appropriate to use 20 square metres and above 2000 watts silicon crystal. If the power is too low, heating effect is not very good and it is demanding.
- Q:Which application fields is HDPE geomembrane chiefly suitable for?
- Environmental sanitation, sewage disposal plant and heap leaching pool: saltern crystallizing pond, settling pond. Polyethylene impermeable membrane is suitable for gardens, plastic straw mat membrane in saltern and impounding pond: 3. salt membrane, vertical core wall: It is suitable for subway, factory farming pools, impounding reservoir and roof garden; 8. High-density polyethylene geomembrane is suitable for petrochemical, twice lining and lining of shrimp pond. 2; 5: Such as refuse landfills, halogen pool cap, afforesting lawn for water and moisture resistance. Polyethylene geomembrane is suitable for mining industry and fishpond: Chemical plants and dissolved pools. Low-density polyethylene film is suitable for transport facilities, sea cucumber circle slope protection, etc. LDPE impermeable membrane is suitable for agriculture, seepage-proofing of ditch, power plant regulating reservoir, green roofs, storage yard, industry, geomembrane solidification, sewage pipe anti-seepage. High density polyethylene impermeable membrane is suitable for salt industry, oil refineries, the pond bottom of golf course: reservoir: 6; 9. It is suitable for the proof seepage of drinking water pond and irrigation system; 10. LDPE impermeable membrane is suitable for water conservancy project and seepage proofing for culvert: Artificial lake, chemical reaction pools, hospital solid wastes, underground constructions of buildings; 4: Intensification, seepage-proof of tailings bottom lining,etc: Such as seepage proofing for rivers, lakes, reservoirs and dams: Washing ponds. HDPE membrane is suitable for the seepage proofing aquaculture industry, ashery, leaking stoppage and oil tank: Road base reinforcement, slope protection, etc.; 7. HDPE impermeable membrane is widely used in municipal engineering, lining of settling pond, revetment, and watercourse. HDPE geomembrane is suitable for environmental protection.
- Q:How thick is the film for furniture? how to differentiate the home film from other films.
- Probably 200 microns thick Ha. Nano-ceramic furniture protective film, referred to as furniture foil, translucent, repairing minor scratches, fire high temperature (225 degrees), radiation (stone furniture), easy to clean, long life, in line with modern green healthy fashion requirements and so on. Applies to: Homes, offices, restaurants, hotels, large and small restaurants, furniture and other ancillary companies. Nano-ceramic film of high transparency furniture, furniture can fully reflect the desktop pattern and color, permanent protection as new. Nano-ceramic furniture foil insulation and ultra-high wear-resistant, so that when you use the desktop will not worry about the furniture scratches and scorch the paint. Nano-ceramic film good decontamination furniture, non-stick oil, smooth surface, do not move, easy to clean. Nano ceramic furniture film does not affect the character of furniture and furniture performance of the premise, to provide protection to the furniture. Nano furniture foil, is the use of high-grade super-transparent polymer with a number of precious metals (such as silver) joint action by sputtering indium oxide, the outer layer of an acrylic-based transparent, very tough. This produced a film with high transparency and heat insulation effect, the surface is very wearable. Nano-ceramic film of high transparency furniture, furniture can fully reflect the desktop pattern and color, permanent protection as new. Nano-ceramic furniture foil insulation and ultra-high wear-resistant, so that when you use the desktop will not worry about the furniture scratches and scorch the paint. Nano-ceramic film good decontamination furniture, non-stick oil, smooth surface, do not move, easy to clean. Nano furniture foil under furniture without affecting the character and performance of the premise of furniture, furniture protection, is the best protector of furniture.
- Q:what are the differences between apple phone diamond film and dull polished stick membrane?
- the differences between apple phone diamond film and dull polished stick membrane: Matte stick membrane: Advantages anti-fingerprint and anti-reflective, the slide hand feeling is good, very comfortable, non-stick fingerprints, there are small scratches and other defects which are not easily seen, the drawback is the visual effect which is not good, grainy, and the feeling like some kind of toilet atomization glass, but not so obvious; diamond film: Diamond belongs to fine grinding, the transmittance is between HD and dull polished and the photopermeability is better than dull polish membrane and it is better than high-definition diamond film pasted diamond flashing effect with more girls.
- Q:Can the mobile phone stick the tempered film
- Of course, the tempered film is used for preventing the mobile phone screen from falling. Tempered glass (TemperedglassReinforcedglass) is a safety glass. Glass has a very good wear resistance, and very hard, its Vickers hardness reached 622 to 701. Tempered glass is actually a prestressed glass, which usually uses the chemical or physical methods to form a pressure stress on the glass surface in order to raise the glass strength. When the glass bears the external force, it should first offset the surface stress, so as to improve the bearing capacity and enhance its wind load resistance, temperature resistance and impact of the glass itself. And the tempered glass protective film is the highest security level for the protection of the phone screen.
- Q:how to use landfill geomembrane at site? ?
- calculate the height of good bulldozers,spread out and compacted by rolling road car. cover a layer of membrane.
