Q:how thickness of the geomembrane is paving in loach pond. .
it is ok for the thickness about 0.35mm
Q:What is the electrical heating film?
The electrothermal film is a kind of exothermic material made of special conductive macromolecule material matched with metal current-carrying strip, hot melted between the insulating film bodies, which will produce heat after being electrified mainly used for heating element. The electrothermal film is divided into high temperature electrothermal film and low temperature electrothermal film. High temperature electrothermal film is generally used in electric products, military and so on, the electrothermal film produced by present science and technology. The low temperature electrothermal film is a kind of semitransparent polyester film which can produce heat after being electrified, which is made by processing and hot-pressing the conductive special ink and metal current-carrying strip between the insulating polyester films. Electrothermal film acts as heating element during work, sending heat into space in the form of radiation, warming the human body and the object first, whose integrated effect is better than the traditional convection heating mode. The low temperature radiation electrothermal film system is composed of power supply, temperature controller, adapting piece, insulating layer, electrothermal film and finish coat. The power supply is connected with electrothermal film through wire, converting the electric energy into heat energy. Because the electrothermal film is pure resistance circuit, the conversion efficiency is high. In addition to a small part of loss (2%), the vast majority (98%) is converted into heat energy.
Q:Which kind of geomembrane that is specially used for impounding reservoir is the best?
There is no brand that is more famous. I suggest you to compare different stores in the local building materials market. The price of this film in normally twenty yuan a square. At present, the plastic films that are used for preventing water seepage are polyvinyl chloride, polyethylene (PE) and EVA (ethylene/ vinyl acetate copolymer). ECB (ethylene vinyl acetate modified asphalt blending geomembrane)is used in tunnels. It is a kind of high polymer chemical flexible material and it has smaller proportion, good extensibility, high adaptability to the deformation, corrosion resistance, low temperature resistance and frost resistance.
Q:What are the sticking methods of computer film?
First step of film sticking: aim the film marked ① at the screen and pull the ① layer of release liner label, slowly tear a part of this layer, pay attention not to touch the adsorbed layer (middle layer) of the protective film with fingers. Second step of film sticking: aim the adsorbed layer at the screen corner, make sure that the position is aligned, smooth the film carefully while tearing off the backing layer ① release liner. Because present protective film has electrostatic automatic adsorption function, generally it does not need be ironed too much. The action should be slow when sticking the film, and it is recommended to start sticking along the long side of the screen, from point to line, from line to surface successively
Q:How about the material of PET film?
At present, PET material is the most common material for film in the market. PET is the copolymer of polyester with high hardness, high light transmittance and high temperature resistance and its sticky veneer can be glued or has static electricity and there are also other options. It is the best raw material for screen protective film so far, and is widely used in mobile phone screen, LCD screen, laptop screen, game machine screen, computer screen, PSP screen and many other fields. The popularity of PET material has presented new direction for cell phone film. It has high light transmittance, can paste again after torn, and the film will not leave residual gum, and there will be no bubble. However, as the saying goes, every coin has two sides, PET film has serious light reflection and will easy be stained by fingerprints. Now there are frosted film and high definition film which adopt this material. HD film has high light transmittance, and the display result is good, but it is easy to be stained with fingerprints and will be obvious.
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:What is the difference between HDPE geomembrane and LDPE geomembrane?
LDPE is softer. HDPE is high density polyethylene while LDPE is low density polyethylene. HDPE is harder while LDPE is softer. And LLDPE, also known as linear low density polyethylene, is much softer. HDPE and LLDPE can be used as manufacturing materials of impermeable geomembrane.
Q:Is lectric heating film electric heater electricity-saving
It depends on two factors, one is the electric heat conversion efficiency, the two is the power. The high the electric heating conversion efficiency, the less electricity it consumes. Well, if we understand this we can analyze whether our household appliances consumes electricity. Power is a fixed value, which is fixed before we buy. For example, we buy a electrothermal film heater whose power is 2000W. This means that the heater consumes 2 kwh of electricity per hour, which is 2 degrees, if it is 1500W, that is 1.5 degrees Electric per hour. The electrothermal conversion efficiency is to consume things unease to know, but we can generally analyze like so: The process of heating is a process that transfers electric energy into heat energy, so we would hope that electrothermal conversion efficiency be higher if we want to get maximum heat. According to the law of conservation of energy, the greatest possibility is 100% conversion. But in fact, the conversion of electric energy into heat energy also includes the conversion into light, (such as small solar heating, which is also luminous in the the moment of heating, a lot of power is converted into the energy we don't need, so the conversion efficiency is low, magnetic energy and other energy. Therefore, in general, the electrothermal conversion efficiency of most heating body is almost the same in the current market, the transfer efficiency of heat body that is not luminous is higher than those giving out lights.
Q:What are the benefits of the water film floor?
Benefits: hard wear anti dust and anti weathering corrosion resistance good curing light environmental protection? Can make concrete whole life longer, quality assurance 25 years: mixed pores of earth surfaces do carefully sealed, can prevent the invasion of oil pollution, and can prevent adhesion of tire India: surface dust more easily removed, with a stop the water penetration, alkalization, dustproof, advantages of weathering and erosion, and more convenient to use, no harm to the environment. Because of the permeability, so it can effectively maintain and develop concrete ground natural and soft and simple and convenient construction, after the construction of the ground without waxing, only water or occasionally mopping the floor with soap and water, will save a lot of repair and maintenance costs, a choice of permanent use
Q:What is the difference between geomembrane and impermeable membrane?
Impermeable membrane is impermeable geomembrane, including geomembrane, composite geomembrane, two cloth a film, a cloth a film. Geomembrane is HDPE geomembrane, geomembrane is a kind of polymer as the basic raw material waterproof barrier material. Mainly divided into: polyethylene (PE) geomembrane, PVC (PVC) geomembrane, chlorinated polyethylene (CPE) geomembrane and a variety of composite geomembrane and so on. Function: seepage, isolation purposes: geotechnical dam, rockfill dam, masonry dam and pressure concrete dam; dike, dam front level anti-seepage cover, vertical foundation impervious layer; tailings dam, sewage dam dam and reservoir Construction of cofferdam; channel, reservoir (pit, Khouang); waste yard; subway, basement and tunnel, tunnel seepage lining; highway, highway, railway roadbed; roadbed and other salt control; Collapsible loess waterproof layer; roof leakage products: two cloth a film (impermeable membrane on both sides with protective geotextile) a cloth a film (impermeable membrane side with protective geotextile) Width: 4-6 meters
