What membrane is recommended for glass in kitchen?
- Use cutting film guide plate as a help when cutting the fenestrated membrane. It can help cutting the fenestrated membrane accurately and smoothly alongside the edge of window glass. Erect the guide plate on the glass straightly or at a natural angle. Cut the membrane with 1mm margin. It is the most important to finish cutting before the final step.s
What are the requirements of using the new geosynthetics?
- 1. In terms of reinforcement, the geogrid should be considered first. 2. The geosynthetics should not be laid directly on the surface of the original foundation. 3. When laying the geotextile material, it should be perpendicular to the axis of the road.s
Does anyone know the mechanism of ion exchange membrane
- 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 nature of different exchange groups, the ion exchange resins can be classified into two categories cation exchange resin and anion exchange resin, most of the cation exchange resin have a sulfonic acid group (-SO3H), carboxyl (-COOH) or phenol (-C6H4OH), etc. and other acidic group, wherein the hydrogen ions can have a exchange with a metal ion in solution or other cation ion, anion exchange resin containing quaternary amine [-N (CH3) 3OH], amino (-NH2 ) or imino (-NH2 ) and other alkali basic group. They can generate OH- ions in water, which can have the exchange interaction with various anions, and the ion exchange resin is in very widely use, it is mainly used for the isolation and purification.s

Imported HDPE geomembrane application engineering and imported impermeable membrane .
- Minerals, the quality of impermeable membrane important ,in particular like some of the projects that causes heavy pollution, heap leaching pool. an upward trend, more and more projects will be asked to use, oil, petrochemical, etc.s
PDHE impermeable membrane in what season can not be built
- No PDHE impermeable membrane, should be HDPE impermeable membrane. HDPE impermeable membrane laying construction climate requirements: 1 temperature 5-40 ℃ is appropriate, taking into account the geomembrane thermal expansion and contraction, according to experience, cold weather, the geomembrane laying should be tight; hot days should be relaxed; But should be noted that in the summer should avoid the high temperature at noon. 2 wind and rain: wind more than 4 or rain should stop construction; wind hours, it is appropriate to suppress the geomembrane sandbags to facilitate construction.

What are the differences between composite geo-membrane and geosynthetic clay liner?
- geomembrane is made of water-proof material for water and seepage prevention. composite geo-membrane is compounded by geomembrane and pervious material. To composite pervious material on geomembrane can protect the geomembrane, increase friction coefficient and permeability in the flat. geosynthetic clay liner is made of two layers of pervious material and one layer of impervious bentonite. geosynthetic clay liner is also used for water and seepage prevention. But because the waterproof and impermeable material is clay which has little, it is not as good as geomembrane in terms of water and seepage prevention. There is a reason for the emergence of the product. Once tiny destructive hole appears, the clay will automatically fill it under pressure, that is to say, it has self-healing effect. The difference between the two: First, geomembrane has better waterproof and anti-seepage effect. Second, geosynthetic clay liner has self-healing role. Third, geosynthetic clay liner has little permeability. As for permeability: The permeability coefficient of geomembrane is less than 10 negative 11 cm3 per second. The permeability coefficient of geosynthetic clay liner is about 10 negative 9 cm3 per second.s
