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:Imported geomembrane anti seepage film width.
thickness specifications, since imported geomembrane has stable chemical properties. HDPE geomembrane among imported products is of best quality, impermeable, waterproof construction is simple, low cost, wide, moisture proof,draining.
Q:Is silicon crystal electrothermal film heater good?
Silicon crystal electrothermal film heater is good. Silicon electrothermal film heater is one of the most popular heating device in recent period. Its working principle is that the inorganic electric conduction membrane made by silicon materials will form hot air curtain, heat convection and far infrared thermal radiation to heat. The volume of this heater is smaller than electric oil heater embodied with all characteristics of the above heaters. And the appearance is like flat plate, more fashionable and more in line with modern people's aesthetic view. Unlike fan heater including sun heater, silicon electrothermal film heater heats up fast and even, has strong ability to resist failure, without electromagnetic pollution due to flat heating. Compared electric oil heater, it has certain advantages in terms of heating speed and energy conversion efficiency. So recently it has become more and more popular.
Q:What are the differences of pvc geomembrane and pe geomembrane?
PE geotechnical membrane is made rom polyethylene raw materials. PVC geotechnical membrane is made of polyvinyl chloride raw material. Domestic projects are now using the former which is environmental-friendly, non-toxic, anti-aging, corrosion resistance, and has developed strict national standards. The latter is rarely produced in China. PVC contains certain toxic chemicals, therefore, water conservancy and environmental protection project does not recommend the application of PVC geotechnical membrane, there does not seem to have the standard requirements of this product.
Q:What are the construction steps of seepage-proof geomembrane?
Composite geo-membrane is an ideal impermeable material which has been widely used in channels, dykes, artificial landscape lakes, plain reservoirs, seepage control and reinforcement of unsafe reservoirs and seepage control of rock-fill dams and other water conservancy projects.
Q:What are the differences between PE geomembrane and PVC geomembrane?
PE geomembrane is made by processing ethylene raw material. PVC geomembrane is made by processing polyvinyl chloride raw material. Domestic projects nowadays all use the former one which is environmentally friendly, non-toxic, anti-aging, corrosion resistance, and strict national standards have been developed.
Q:What are the requirements of geomembrane waterproofing construction for the base?
Level compaction, sharp object namely
Q:What is the construction method of the geotechnical membrane?
The construction method: To lay it in the range of measurement. To lay the composite geotechnical membrane before the first required to lay a good sand cushion on the roadbed, laying the width of the design requirements set. When laying, do not allow the laying of folds, as far as possible to tighten. After the pavement, the U type nails or bamboo nails is used to fix. When laying composite geotechnical membrane, the surface of the sand layer is smooth, no hard protrusion, and timely fill sand cover, avoid direct exposure to the sun for a long time. When the composite earthwork film is laid, the length of the transverse lap and the longitudinal lap can meet the design requirements. After the composite geotechnical membrane is rolled out, the filling material is filled up in time, and after the soil is covered with light compaction mechanical compaction, only when the thickness of the overburden layer is larger than 0.6m, the soil can be compacted by heavy compaction machine. Composite geotechnical membrane according to the design requirements can be divided into two types of longitudinal force and lateral force, the laying of composite soil before the film to understand the design intent, strictly according to the design requirements of the laying.
Q:Does anyone know the mechanism of ion exchange membrane
the mechanism are as follows: Ion exchange resins are high molecular material with an ion exchange function. in the solution, the ion of itself will have an exchange with the ion which has the same symbol in the solution. According to the different nature of the exchange groups, the ion exchange resin can be divided into cation exchange resin and an anion exchange resin. Most of the cation exchange resin has a sulfonic acid group (-SO3H), carboxyl (-COOH) and phenol (-C6H4OH) and other acidic group, wherein the hydrogen ions in solution can have an exchange with a metal or other cation. For example, the polymers of styrene and divinylbenzene by sulfonation is giving strong acid cation exchange resin and the structure can be simply expressed as R-SO3H, wherein R represents a resin matrix, the exchange mechanism is 2R-SO3H + Ca2 + (R-SO3 ) 2Ca + 2H this is the mechanism of water softening. Anion exchange resin comprises quaternary amine [-N (CH3) 3OH], amino (-NH2 ) or imidogen (-NH2 ) and other alkaline group. They can generate OH- ions in the water, and have exchange interaction with a variety of anions, the exchange mechanism is R-N (CH3) 3OH + Cl- R-N (CH3) 3Cl + OH- due to the ion exchange is reversible, so the used ion exchange resin is suitable to wash with acid or base resin with a suitable ion exchange concentration, to restore the original state and repeated use, so the process is called regeneration. cation exchange resin can be washed with dilute hydrochloric acid, dilute sulfuric acid solution; the anion exchange resin can be treated with sodium hydroxide solution, etc., and then reproduced. ion exchange resins are widely used, and it is mainly for the isolation and refinement. For example, softening water system and producing deionized water, recycling metal in industrial wastewater, separating rare metals and precious metals separation and purification of antibiotics.
Q:Which kind of computer anti-reflective screen film is better?
Personally recommend the following kinds: Film of PP material is soft, with poor translucency, having no function of anti-scratch and anti-abrasion, which can only prevent dust. Since the result is not good, it is now basically abandoned by consumers. Film of PVC material is soft and easy to paste, but relatively thick, whose light transmittance performance is not very good. And if tearing down the film, there will be residue on he mobile phone screen, affecting the appearance. Film of PET material has high translucency, which has no residue after being peeled off and small bubbles in the middle of the film. But, the film has higher reflectance, preventing users from clearly seeing the words on the screen, and easy to leave fingerprints and other traces on the surface at the same time.
