Q:What should be paid attention to when installing electrothermal film?
After the completion of the installation of electrothermal film floor, in addition to the routine acceptance inspection, the most critical aspect is to conduct warming acceptance inspection for the floor.
Q:How many gram is composite geomembrane?
Q:Which kind of the mobile phone screen protector is better?
Films are generally divided into two types of membrane of high grade of transparency and frosted membrane. Membrane of high grade of transparency has high permeability through the natural brightness, it looks bigger brightness, but the drawback is reflection of light in the bright place which will make you harder to clearly see the text on the screen. But the frosted membrane has uneven surface, it is diffuse reflection when the light shines on it, so the screen will not be too harsh but soft with low light transmission.
Q:How to distinguish 3D tempered glass film and tempered film?
One border has color, and the other hasn't. The quality and the tempering effect are valued in tempered film. Which company produces good raw material and tempered film with good strength, they must be good.
Q:Can PET film be used as thin film of the case sealing tape?
PET film can not be used as a thin film for case sealing tapes. PE tape is made from polyethylene, and the film is soft with low intensity, and it is commonly used in protective films. PET tape is made from polyester, and the film has high strength with good insulation performance, and it is commonly used in the insulation of electrical and electronic products.
Q:what's the standard that geomembrane welding point's breaking strength should reach?
welding point strength is executed by GB/T16989 standard, the products standard of composite geo-membrane is GB/T17642-2008 .
Q:What's the question need to notice about the construction method of composite geo-membrane?
1) clean up embankment slope, flat ground, remove all sharp corner sundries, backfill and tamp, pile the slope is qualified acceptance by supervisor, providing a operating face for paving the composite geo-membrane. 2) as for geomembrane split joint, for the sake of convenient construction, ensure the quality of split joint, composite geomembrane should as far as possible use wide range, decrease the field splice quantity , before construction, in accordance with the requirements of composite geomembrane width and scene length demands, it should be cut inside the unit, and spliced into the required size block, to roll it on the steel pipe, manual handling it to the working face.
Q:What concrete acceptance criteria?
Concrete acceptance specifications and requirements 1, before the opening of concrete, the use of cement, sand, stone and other materials must be tested with a test. Raw materials before using. After opening the site to extract the raw material must require concrete specimens (Party present). 2, concrete construction under certain conditions as much as possible the overall situation watering, special circumstances must be positioned indwelling construction joints according to design requirements, while continuing construction Peng expansion construction joints must be treated like about the norm. Concreting within 12 hours after the designated persons must cover and conservation. 3, sand, stone and clay content must be strictly controlled: Sand clay content: When the concrete strength ≥C30 when clay content ≤3% when the concrete strength grade x26lt;C30 when the clay content, clay content ≤5% stone: When the concrete strength ≥C30 when clay content ≤1% clay content ≤2% 4 when concrete strength grade C25-C15, the amount of water strictly concrete: Ensure the workability of concrete, slump, slump concrete field sampling tests qualified, it is strictly prohibited. He said the pound used should always check. 5, strict quality-situ concrete to avoid the common problem occurs: Exposed tendons, cellular, holes, clip ballast, loose, cracks, missing edge off angle, not straight edges, uneven warping, burrs ribs, peel from the sand, deformation Inflation ran mold displacement. Then hew false and so on.
Q:How to choose the glass stick membrane Sunscreen film?
How to choose the glass stick membrane Sunscreen film: 1. From the abrasion resistance, it can be divided into low abrasion resistant coating layer, wear-resistant layer and not wear-resisting film. So after we get a piece of architectural membrane, the first is to distinguish its protective layer, and then rub it on the wear-resistant layer to see if it will produce pattern. If there is the decorative pattern, it is the low level; If there isn't the decorative pattern, it is the middle or high level film. 2. To see whether there is electrostatic attraction, due to the low membrane uses a little metal materials. So when it is being rubbed, it will slide from left to right; but to the high-end film, it has a kind of electrostatic attraction due to it with a lot of metal materials, and it is not sliding when rubbing. 3. The first is to see whether the plating layer is uniform, pick up a piece of building film to see whether it is uniform. If it is even, it is the good quality film. If it is uneven, it is the low quality film. 4. According to the analysis, because the heat insulation effect of different grades of film solar is not the same, so we adopt the high power lamp (500W--700W) to irradiate on the surface of the membrane. If the insulation effect of the low-grade membrane is poor, the hot will be felt even across the film. But for the high-end film, there is hardly any calorie that can penetrate it, so the hot will not be felt across the membrane. 5. The carburetor cleaning agent test method is to make the floor friction or the oil cleaning agent with a piece of film (also known as "cleaning agent") spray on the membrane. The fading inferior film is usually said tinted film. The film not fading is the high-end film, also known as the film of primary color. In summary, the building film with high transmittance and high thermal insulation is the high-grade film.
Q:What's the method of adhering glass film to the window?
For adhering glass film to windows, you should be careful at every step, otherwise the film will be crooked or crumpled. 1. Clean the glass. Wash the glass thoroughly to make sure there is no soft flocks, dust or sand on the glass. 2. Cut the glass film according to the size of the glass. 3. After cleaning the glass, spray some water on it. 4. And meanwhile spray some water on the glass film and protective film, and separate the protective film from the glass film. 5. Scrape the water between the glass film and the glass slowly, and trim off the excess glass film at corners.
