- Q:Waterproof geomembrane convergence is not good, the joints touch the top of the cement is necessary?
- It's useless! Cement is water permeable! Geomembrane manufacturers to answer!
- Q:Does the mobile phone stick the tempered film or ordinary film?
- The tempered film is very good, mainly because it is more durable, which can protect the mobile phone screen, and the quality of the tempered film is very good. Ordinary film is easy to break the phone screen, the protective effect is weak, but also it should be replaced frequently.
- Q:Geomembrane's introduction
- Geomembrane, geotextile and geomembrane belong to composite permeable material, mainly used for impermeable geomembrane, cloth membrane and two cloth membrane, width 4-6m weight 200-1500g / m2 tensile, tear-resistance, bursting and other physical and mechanical properties, it can meet the demands of water conservancy, municipal, construction, transportation, iron, tunnels and other civil engineering, due to its selection of high material and production process of chemical warfare agents added so non-regulated temperature environment to test the quality indicators per unit area (g / m2) 400 500 600 700 8009001000 Notes membranes degrees (mm) 0.25-0.35 0.3-0.5 breaking strength (kN / m) 5 7.5 10.0 12.0 14.0 16.0 18.0 CBR top crossbar to break strength (kN) 1.1 1.5 1.9 2.2 2.5 2.8 3.0 tear strength ( kN) 0.15 0.25 0.32 0.40 0.48 0.56 0.62
- Q:What's the function of the base membrane of wall cloth?
- It can prevent fungal growth, better plays the role of linking the wallpaper with the base, and is convenient for secondary pasting.
- Q:What are the quality inspection and control methods of HDPE geomembrane in impermeable membrane construction?
- HDPE geomembrane in the anti-seepage construction quality inspection method 1: laying anti-seepage membrane should be civil engineering corresponding to the corresponding acceptance of documents. 2: anti-seepage film before cutting, it should accurately measure the relevant size, and then according to the actual cutting, generally should not be cut according to the size of the figure, should be piece by piece number, detailed records in the special form. 3: laying impermeable membrane should try to weld at least, in ensuring the quality of the premise, as far as possible to save raw materials. But also easy to ensure quality. The lap width of the joint between the membrane and the membrane is generally not less than 10 cm, usually in the direction of the weld arrangement parallel to the maximum slope, that is, along the slope direction. 4: usually in the corner and the deformity of the lot should be shortened in length. In addition to the special requirements, in the slope of more than 1: 6 on the slope from the top of the slope or stress concentration area of 1.5 meters, as far as possible without weld.
- Q:What is the unit price of geomembrane?
- The material for geomembrane production is high density polyethylene, refined from petroleum, whose price depends on the international crude oil prices. Currently, the price trend is stable and there is no big change in price. About 3 yuan / piece. Geomembrane construction site the main mechanism is to cut off earth dam leakage passage by using the imperviousness of plastic film, bearing hydraulic pressure and adapt to dam deformation with its greater tensile strength and ductility; non-woven fabric is also a kind of polymer short fiber chemical material, through needle punching or hot sticking forming, with high tensile strength and extensibility. After it is combined with plastic film, it not only increases the tensile strength and puncture resistance of plastic film but also because of the roughness of woven surface, increases the friction coefficient of the contact surface, which is conducive to the stability of geomembrane and protective layer. At the same time, they have good errosion resistance to bacteria and chemical action, not afraid of acid, alkali and salt erosion. It is used in dark places with long service life.
- Q:What are the advantages of the glass reflective film?
- It is anti-ultraviolet, can block more than 95% of ultraviolet rays, and while insulating heat, it can reduce the damages to household articles and people's skin caused by ultraviolet rays. These are the main reasons why consumers like it, It is healthier: The adhesive inside the glass reflective film contains UV (ultraviolet) absorbent which can block 98%-99% of UV rays. It is safer. For the ordinary heat-insulating film, it has certain security enhancement, and meanwhile can stick to debris like the reflective clip (adhesive) glass. It is better than toughened glass in security.
- Q:The features of HDPE geomembrane
- As a new material, geomembrane has excellent anti-seepage effect, corrosion resistance and chemical stability. And it can process features and functionality according to the actual project needs. Geomembrane has been widely used in water conservancy embankment dam , reservoir seepage. At the same time, it has ben widely used as seepage-proof, anti-corrosion, leakage-proof and non-hygroscopic material in channel, impounding reservoir, cesspit, swimming pool, house building, underground structure, wasteyard, environmental engineering, etc.
- Q:The methods for sticking mobile phone film?
- 1. The environment: The place that need to be pasted with film should be in the bright light. If the indoors' light is too weak, then the small table lamp should be prepared to looke the details clelight is bright enough, indoors if too black is ready to small table lamp, light enough to see details. 2, wash their hands: First, clean up the dust and grease on the hand. Pay attention to use the liquid soap to wash. 3. Wiping the screen: Wipe the screen with a special fibre screen cloth, general senior film have specialized attached, if there is no can also replaced with glasses cloth or dropping the soft cloth, dip a small amount of water or special screen cleaning agent to rub, to clean up the clean surface dust, fingerprints for quasi. 4. Begining to paste: The tab 1 The thin film is the protective layer rather than the using layer. To tear off the label from table 1 slow, then align the up and the left of the screen and paste it on. 5. The process: When pasting the film, keep a constant speed. And when there are appearing bubbles, please pull back and ensure no bubble on the surface. Then scraper the blade with wool scraper or cushion. You should scratch it slow to avoid damaging it. To press the surface of the mobile phone, the instant bubbles will be very small. 6. To repair: After pasting, and then make a restoration of the bubble in some areas. Use the hard card and credit card, just wipe the card with the soft cloth and slowly scratch the bubble out of. If there are any small dust particles on the surface, please uncover the block and paste it up with the adhesive plaster, and then paste the stick membrane well. If the good paste screen is only with only tiny bubbles, it generally disappears within a week automatically.
- Q:What is the installation technology of soft membrane?
- When installing the soft membrane, the first is to install the four angles of A, B, C, D, then the diagonal pull point installation, finally all installation. The installation sequence: 1. Before the entering of the soft film smallpox, the site must be electrified and without construction waste. 2. The deal with the bottom of the piamater ceiling should be fit for the installation conditions, such as the installation of the steel and so on; it must be cleaned. 3. All the installation of the lights must be according to the requirement of us. We should ensure all of the circuit to be electrified. If there are any lamp not lighting up before installing the soft film, it should be adjusted and repaced in time. The interior hidden lights should be painted with white paints so as to get a better effect. 4. The air conditioning and fire pipes must be arranged in advance and debug to keep it operating well. After the installation of the air inlet, spray head, and smoke sensor, all of them should meet the requirements of us. 5. After the installation of the piamater ceiling is completed, for example, the paint should repair the gypsum board and should not touch the soft film smallpox.
