Q:Is the decorative film environmental friendly?
The decorative glass membrane is generally used for tooling, its role is mainly reflected in a decentralized direct light, logo marking and so on. And the decoration glass is frosted glass or diamond glass, high-grade point is art printing or embossing glass.
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:How is rexva electrothermal film?
Electrothermal film has been developed for many years. In terms of energy-saving effect, when the electric film is just installed, it is very energy efficient. Its electric - thermal conversion efficiency is about over 80% in the first year after installation, but the most fatal flaw is that the aging rate and thermal efficiency decreasing is too fast at an annual decline rate of about nearly 10%, thus causing after one or two years electricity consumption will become increasingly large, three years later it will be close to that of the heating cables. In addition, the service life of this product is not long and it has high rate of breaking down, so it has been obsoleted in the market.
Q:Does the geomembrane be used as an experiment?
Of course, the standard is GB / T-2008 "geosynthetics non-woven composite geomembrane" revision. This standard specifies the nonwovens composite geomembrane product classification, specifications, code, technical requirements and quality assessment, test methods, inspection rules, packaging, signs, storage and transportation. This standard applies to non-woven geotextile as the substrate, with polyethylene, polyvinyl chloride and other films, composite non-woven composite geomembrane. This standard is the GB / T-1998 made the following technical changes: - standard name changed to "geosynthetics non-woven composite geomembrane"; - product specifications from the unit area of ​​the quality to nominal breaking strength; - the product code is simplified from 7 parts to 5 parts; - the original standard in Table 1 and Table 2 for integration, fracture strength, tear strength, CBR burst strength indicators are specified specific indicators, and increase the file requirements ; - the elongation at break is changed to the standard strength corresponding to the elongation; - the width is changed to the reference index, the mass per unit area is no longer used as the assessment index; - simplifies the appearance inspection; - simplifies the packaging, standard.
Q: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.
Q:Can all-purpose adhesive stick composite geomembrane?
The best way to stick composite geomembrane is to weld with sweat soldering machine or monorail welding gun. If there is no such device on the construction site, you can brush PE adhesive, or use all-purpose adhesive. Brushing must be uniform, and sticking should be close and tight. Brushing surface must be kept clean without water or mud. Brushing all-purpose adhesive is relatively expensive.
Q:Is it safty to use the infrared electrothermal film floor heating?
Product itself has no problem, but now as the country does not have the construction atlas, it lacks an authoritative guidance to the construction, the construction technology of construction units is not different, some small construction team can not grasp the key working procedure, it will appear tripping after make it
Q:Should geotextile be laid under the geomembrane in the fish or shrimp ponds?
It is unneccessary. Now the technology of geotextile is mature, so the quality of it will not be too bad. Paying great attention to the brand is also completely unnecessary. I would ask do you check the brand when buy pork? No. All pork is bought from the pork satll. There are only two possibilities when you attach too much importance to the brand. 1 you are advertising for yourself. 2, you do not understand the market. I suggest you buy it in the nearnest shop.
Q:European electrothermal film is good
electrothermal film is made of polyester film. When working with electrothermal film as a heating element, the heat is sent into space in the form of radiation , the human body and the object first get warm, and the combined effect is better than traditional convection heating. low temperature radiation electrothermal film system consists of power supply, temperature controller, adapting piece, insulating layer, electrothermal film and finish coat layer. Power supply via wires connecting the electric film, turning the electric energy into heat energy. Since the electrothermal film is purely resistance circuit, so the high conversion is efficient, in addition to the loss of a small portion (2%), the majority (98%) is converted into heat energy. Electric film can not be directly used for radiant floor heating, it needs to add additional patent PVC vacuum envelope, thus it can be used for floor heating, and ensure the use effects and life.
Q:Does iphone need to stick membrane?
iPhone can be sticked with membrane: 1. High-definition film is thin, and the visual effect is good. However, it is easily scratched; 2. Frosted film is also thin, but its visual effect is not so good without fingerprint; 3. Tempered film is thinner, and its visual effect is good and resistant to scratch.
