Q:How is PTC electrothermal film?
PTC is positive temprature coefficient which means when the temperature of the heating element rise, its resistance will rise (ordinary metal material has the characteristic, but the resistance of the material increases rapidly with the rise of temperature ), and the heating power decrease, and it will not reach the ignition point because of local covering lead to sharp rise in temperature. It is also known as self-regulating heating element, that is, the material itself has the function of limiting the rise of temperature , rather than limiting the temperature through the laid temperature sensor on the ground. Due to the characteristics of PTC, it is considered as a safe electric heating in the market, so many do not have the characteristics of the PTC material, also boast they are. This should be paid attention to.
Q:What is the power of electric heating film
M2\110w---M2\400w100M2 cases Its minimum per square 80 watt is 8000 watts per square 130 watts is 13000 watt maximum and minimum installation depending in production of insulation. That is to say good insulation shop less, and vice - electricity actual wattage the actual number of days of consumption divided by 2
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:How to use the mobile phone laminator?
Mobile phone laminator has many advantages, such as wide compatibility, good effect of sticking film, simple operation, multipoint operation, safety and saving materials; mobile phone laminator is fully compatible with the brand transparent protective film and a variety of digital products, such as mobile phones, MP3, MP4, camera, remote controller and notebook computers. It is fully mechanized in the whole process, sticking the mobile phone film is remarkably smooth with no bubbles and no wrinkles. Besides, it has good safety and free of grilling. Fool-type operation just need to press the button, it will have the best quality, you do not spend much time to practice the sticking film technology, everyone can become a master of sticking the film, it can be finished the whole process in three minutes, which reduce the waiting time of customer, and improve the efficiency of 5 to 10 times. A machine is equal to three skilled master, you make money faster and easier. Mobile phone laminator is equipped with a variety of templates with flexible configuration, which can save the raw materials. It reduce the consumable items by 50% to 80% than the fixed consumable items area of tranditional sticking method.
Q:Can geomembrane be used in building a methane tank?
Measures should be taken to prevent seepage in the methan tank.
Q:what's the items needed to be noticed in the pavement of composite geo-membrane?
(5) construction, transition layer: (1) embedded method should be used: covering thickness should be not less than 30cm (2) it shall ne equipped with impervious system renovation, both ends buried in the soil is corrugated: Cushion, protective layer, impervious barrier. (4) the geomembrane should not be pulled too tight while paving. (3) soil should be solid, while laying the film .. laying small diameter sand or clay on the contact surface as a protective layer to avoid uneven subsidence, cracks, it should be best paved while construction, within seepage-proof scope, turf and tree roots should be cleaned, especially while anchored with the rigid material, there should be a certain amount of stretching. Construction notes, while covering the protective layer: laying note of geomembrane, heavy direct hit in the geomembrane
Q:What is the composite geomembrane, how to define it?
It's the combination of geotextile and geomembrane, there are two fabrics and one membrane and one fabrics and one membrane,
Q:Introduction of geomembrane
Geomembrane plastic film used as seepage-proof base material and combined with woven cloth geotechnique seepage-proofing material new material geomembrane anti-seepage property mainly depends on plastic film anti-seepage property at present at home and abroad seepage-proof application plastic film mainly include polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), tunnel practical design using ECB (blending geomembrane of ethylene-acetic acid-ethylene modified asphalt) a kind of high polymer chemistry flexible material, with small proportion, strong extensibility, high adaptability to the deformation, corrosion resistance, low temperature resistance and good anti-frost property.
Q:Which one is better, geotextiles or composite geo-membranes?
Different products have different properties.
