Q:Should the protective film of the refrigerator be torn off?
So its protective film should be torn off. Protective film plays the function of protecting the appearance of the refrigerator. A new refrigerator is packaged with a large plastic bag in the carton, which can make sure that its protective film can be maintained in good condition and easily torn off. But when the refrigerator is unwrapped and put into normal use, the protective film in the air may dry out after a long time. And after a few years, the film will become brittle and tightly attached to the surface of the refrigerator, and produce crack for environmental reasons, which will affect the beauty of the refrigerator and make it very difficult to tear off the protective film. Therefore, the protective film should be torn off soon after the refrigerator is unwrapped.
Q:Construction technology of geomembrane:
Notes for geomembrane joints: (1) the joint treatment of the geomembrane is the key process of construction, which directly affects the service life of the project. Indicated by quality test, hot weiding is an ideal way. (special adhesive is also available). Heat welding method is heating the surface which is connected with the PE geomembrane, the surface melting, and then through the pressure to merge them into one, (2) Geomembrane shall be paved along a certain direction, on both sides of the geomembrane should be reserved for certain PE membrane and PET membrane bonding layer.While paving, we should adjust the tendency of geomembrane of each unit, in order to bring convenience to two units geomembrane welding. (3) Press geomembrane with sand bags to prevent wind after pavement, edge joints requires no dirt, moisture, dust, etc.. (4) before welding, adjust the joint at two sides of PE membrane, jointing them with broadband, and making them smooth, and no wrinkle. (5) When welding, it is better to have a technical personnel of certain experience, and use a special welding machine for welding. Adjust the temperature and speed, (can also use adhesive to bond). According to many years of practice, it is proved that the thickness of the geomembrane is not less than 0.25mm, because too thin is possible to produce porosity, and it is easy to be damaged in the construction to reduce the seepage control effect. During the construction of geomembrane, we should pay special attention that the pavement should not be too tight, shouldn't wrinkle, and the jointing should be firm. We should construct strictly according to the technical specifications, checking five quality clearance comprising preparation, paving, splicing joints, testing and backfill.
Q:What's the technical standards of geomembrane?
The national standards of geomembrane is GB / T17642-2008. Geomembrane 1. longitudinal and transverse breaking strength. 2. Vertical and horizontal elongation corresponding to the standard strength. 3. CBR bursting strength 4. 5 vertical and horizontal tearing strength. 5, hydrostatic pressure resistance. 6. peel strength. 7. vertical penetration index. 8, width deviation, the above technical requirements that confirm to the national standard are national standard geomembrane.
Q:Water pond impermeable or membrane geomembrane.
geomembrane and impermeable membrane film called both with the same kinds of products like water ponds geomembrane HDPE (High Density Polyethylene) Material Material HDPE geomembrane seepage effect in addition to having good outside with higher puncture resistance, tear resistance, resistance to current standard of ability HDPE geomembrane two standard type that is standard (GB / T17643-2011 GH-I), marking the second type (GB / T17643-2011 GH-II) using standard like ordinary water pond HDPE geomembrane according to user type from the water depth with procurement thickness HDPE geomembrane.
Q:What is the electric film floor heating?
Under the electric field, the carbon molecular group of the heating element of the electrothermal have a "Brownian motion". There are serious friction and impact between the carbon moleculars, producing the heat energy transcend externally in the form of infrared radiation and convectional. The conversion rate of the electricity to heat energy is up to 98%. The function of the carbon molecular make the surface of the electrothermal filmheating system heated quickly. Installed the far-infrared heating system on the ground, then the heat will flow evenly to every corner of the room. The far-infrared carbon crystal can quickly heat the space because the input 100% electricity can be effectively converted into 66% far-infrared power and 33% convectional heat energy.
Q:How to install the electrothermal film non-woven fabrics?
After taking ground insulation measures, then clean the ground so as to keep it smooth and flat. Then lay the aluminum foil reflective film, and then pave the electrothermal film. The electrothermal film should be face up, and a safe distance between films of around 20 cm is recommended to reserve. Then connect wires and electrothermal film should be in parallel with wires. Both ends are insulated. Waterproof cloth should be covered after finishing the installation of electrothermal film.
Q:What are the uses of geotextiles?
Geotextiles are new building materials. They made from synthetic fiber of high-molecular polymer, namely the dacron, acrylic, chinlon, etc. According to manufacturing method, geotextiles can be divided into two categories, namely the woven geotextile and non-woven geotextile. The geotextiles have functions of seepage control, filtration, dewatering, separation, reinforcement, protection, seal, etc. Compared with common stone and concrete, geotextiles have properties of low cost, simple construction technology, short construction period, good anti-seepage effect, channel efficiency. Geotextiles can be used for filtration in dams and revetments, for separation and seepage control in channels, for separation and dewatering in roads, railways and runways, for reinforcement and dewatering in slopes, retaining walls and pavements, for treatment in soft grounds of the ports, causeways and wharfs, for separation and seepage control in landfills, ash dams of heat-engine plants and tailings dams of dressing mills. Geotextiles are now widely used in the field of construction of infrastructure and will be used in broader fields.
