- 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:What are the requirements of the cusion layer on the geomembrane? Do we need to make construction?scheme ?

- Q:How to determine the soil moisture content?
- To estimate the best water content of soil, and then from the best in order to two points each with two groups, the water content in turn decreased by about 2%.
- Q:What are the technical points of the lioghtweight foam?concrete?
- 1. To clean the surface and ensure that there is no dust and dirt of the grassroots, for smooth, solid, light pressure, does not allow rugged, loose and sand off ash and other defects. 2. To make a good preparation of the materials, the foaming agent, additives, cement and auxiliary materials should be transported to the designated place for storage. 3. It should be leveled according to the design. First, take use of the cement mortar according to 2.5x2.5m to determine the height of the slope. 4. To start the foaming machine to start to work, and then start the host. To sent the cement into the agitator with the help of the conveyor?belt/band carrier. And after it is mixed uniform to start the transportation system of foam conveying system and high-pressure pump. And then mix the concrete composite material averagely and transport them to the disignated construction area to cast. 5. According to the requirements of the construction, the professionals will smooth the castin foam concrete. (with help of the smooth floating ruler) Because after it is being smooth, the surface of the foam cement will produce a little air void which will have a bad effect of the surface of the waterproof construction. It is suggested to establish the 70% final set of the casting foam concrete and use the cement mortar to smooth and protect. 6. When the integral casting of foam concrete has reached 4000 square meters and the final set of the concrete has up to 70%( It is generally 25 centigrade and 36 hours). The cut of the dividing joint should be in time. And the width of the dividing joint should be bigger than 4x4m. The the width and depth of cutting of every dividing joint should be calculated by 1/800 telescopic value of the thermal efficiency expansion. The deepth of the width of cutting is 1.5x3.0cm, the elastic sealing material will be sealed in after the cutting.
- Q:How do geomembranes contribute to the prevention of soil erosion in coastal protection?
- Geomembranes contribute to the prevention of soil erosion in coastal protection by acting as a barrier between the soil and water. They effectively prevent the erosion of soil by limiting the contact between water and the underlying soil, thereby reducing the impact of waves, tides, and currents. This helps to maintain the stability of coastal structures, such as seawalls or embankments, and protects the underlying soil from being washed away. Geomembranes also help to control the flow of water, directing it away from vulnerable areas and reducing the risk of erosion. Overall, their use in coastal protection plays a crucial role in preserving the integrity of coastal ecosystems and preventing the loss of valuable land.
- Q:What are the factors to consider when selecting a geomembrane for a specific application?
- When selecting a geomembrane for a specific application, there are several factors that need to be considered. These include the required strength and durability of the geomembrane, its compatibility with the intended environment and chemicals, the desired permeability or impermeability, the installation method and ease of installation, as well as the overall cost and availability of the geomembrane. Additionally, factors such as the expected lifespan, maintenance requirements, and environmental sustainability should also be taken into account.
