Q:What are the precautions for the construction of the slope area of the cesspit?
The construction method of geotextile/geomembrane: 1 flatness: ±2cm/m2, flat and straight; 2 compactness: 95%, after grinding, pave geomembrane on the surface; 3 vertical and horizontal gradient: Longitudinal and transverse slope should be above 2%, boundary and structure of the landfill bottom must be beneficial to diversion of leachate; 4 cleanness: No roots, rubble, gravel, concrete particles, such as sharp edges shall appear within vertical depth of 2.50cm . Climate requirements while paving: 1. Temperature: 5 - 40℃ is appropriate. Taking into account thermal expansion and cold contraction of the geomembrane, according to experience, when the weather is cold, geomembrane pavement should be tight; in hot weather should be loose; but it should be noted that, in summer, high temperature should be avoided at noon. 2 wind and rain: If the wind scale is over force 4 wind or it's raining, the construction should be stopped; When wind is lessened, it is proper to hold down geomembrane with sandbag so as to facilitate construction. Construction and installation of HDPE geomembrane: 1 construction and installation process of HDPE geomembrane. 2 tailor and transportation: According to the records of laying base measurement , cutting large bundle number of geomembrane should be marked and recorded and then carried to construction site according to their number.
Q:What is the difference between dc film sticking and mobile phone film sticking?
The benefits of mobile phone film sticking: It is scratch resistant, fingerprint resistant and dust resistant. Nowadays, all phones are advised to stick a protection film. If you don't stick a film, the screen is easy to be scratched.
Q:how thickness of the geomembrane is paving in loach pond. .
5CM
Q:Is the geomembrane bag made of geomembrane or geotextile?
The two layers of geomembrane bag are made of geofabric not geomembrane or geotextile, mainly used for the watercourse before the revetment (environment friendly geomembrane bag).
Q:Geomembrane's application technology
Q:What is the method of sticking membrane on cabinet?
First, clean cabinet surface. It is recommended to use medical alcohol with 75% concentration, which is easy to clean and dry. Measure the length, width and height to stick with tape, then cut on the purchased membrane. To avoid waste, you'd better draw on draft paper. Finally, stick from top-down, and stick right bit by bit, or it would be difficult to handle if you find slanting in the end.
Q:Can 1.5mm geomembrane be produced by blow molding?
Yes. The film reaching the standard is all produced by blow molding.
Q:How to construct the bottom of geomembrane oil tank?
Construction of oil tank is more troublesome, and it should comform to construction drawings. There are professional welders and welding equippment, you may start weld after pavement.
Q:Which one is better, electric heating film and oil heater
Personal feeling or I think that electric oil is better, safe.
Q:How to use electrothermal film?
1. first, electrothermal film should set reasonable temperatures. 2. The required voltage of electrothermal film is 220V, the electricity consumption must be ensured to meet the requirements of electrothermal film and the security of external power. (low voltage, decreased heating speed) 3. do not use force to impale or strike the surface that is paved with electrothermal film; 4. the surface temperature of the electrothermal film should be less than 60 degrees, if the temperature is too high, the temperature should be lowered to prevent empyrosis. 5. the electrothermal film can not be soaked in water, water on the ground should be cleaned in time, if the electrothermal film is soaked in water, please stop using immediately, and contact professionals to detect. 6. the heating equipment cannot be added on the ground surface which is paved with electrothermal film equipments. If there is additional equipments, technicists are need. 7. Thermal insulation materials can not be paved in a large area on the ground surface which is paved with electrothermal film equipments, such as: Foam blankets, yoga mats, quilts, carpets that is more than 3mm in terms of thickness, etc. The ground should be ensured of a good heat dissipation environment. 8. the electrothermal film heating equipments should be closed if there is nobody besides them.
