Q:What is the material of the decorative film ?
Q:How to get rid of protective film of the security door?
The protective film of installed security door must be torn off within a month, otherwise it is difficult to tear. If the film has remained over a month, you can find a place where the film has already cocked and coat some essential balm where the film meets the door, then peel it a little, and coat the essential balm and peel. After several times, it will be easier to peel, so be patient!
Q:What is the water proof method of electric heating film?
On average: 1 Using electric heating film to control temperature is convenient, flexible, need no human monitering . 2 electrothermal film heating can avoid economic losses resulted from frozen greenhouse seeding due to sudden decrease of outdoor temperature. Temperature can be freely adjusted by using electrothermal film heating to achieve temperature rise and decrease. 3 Using electrothermal film heating , plant will grow strong root and can directly be transfered to outdoor plants.
Q:Can geomembrane HDPE replace waterproof roll modified asphalt sbs to be used in architecture?
Does not meet the SBS construction conditions SBS can not conduct construction on the waste plant, because the base under the waste plant is soil layer; flat
Q:Does computer need to stick screen protecting film?
Generally the screen doesn't need to stick film, if it is anti-dazzle screen, do not stick film, because the screen will not anti-dazzle after sticking film. 15-inch film cost less than 2 yuan, whose characteristics of anti-static, anti-scratch and good heat dissipation are bluffing, tell you the price is 20 yuan,50 yuan or 80 yuan, actually the film they stick for you is the cheapest. Heat dissipation performance of dell machine is not good, 15tr has high configuration but the screen technology is the same with14r and15r , , if you want to use in relatively clean environment, and keep better maintenance for your computer, do not stick film.
Q:How to deal with the waterproof membrane on balcony?
1. Cleaning the construction site and wetting it thoroughly without leaving accumulated water. 2. Walls: The total thickness of the waterproofing layer (waterproof mortar plus waterproof mortar prime) should be not less than 10 mm and its height should be not less than 1800 mm. (1) The waterproof simple mortar is made by mixing the Laoyaer waterproof mortar with cement. Then the waterproof simple mortar should be plastered on the cardinal plane for twice and its thickness should be 2mm. (2) About 20 minutes later, the waterproof simple mortar should be dried. Then you can mix the Laoyaer waterproof mortar with cement and sand to make waterproof mortar and plaster it on the surface of the waterproof simple mortar with the thickness of 8 mm. (3) After the waterproof mortar layer is solidified 24 hours later, you can spray water on it for maintenance. 3. Floor: The total thickness of the waterproofing layer (waterproof mortar plus waterproof mortar prime) should be not less than 20 mm. (1) The waterproof simple mortar is made by mixing the Laoyaer waterproof mortar with cement. Then the waterproof simple mortar should be plastered on the cardinal plane for twice and its thickness should be 2mm. (2) About 20 minutes later, the waterproof simple mortar should be dried. Then you can mix the Laoyaer waterproof mortar with cement and sand to make waterproof mortar and plaster it on the surface of the waterproof simple mortar with the thickness of 18 mm. (3) After the waterproof mortar is solidified 24 hours later, you can spray water on it for maintenance.
Q:Is electrothermal film safe?
1, this problem is hard to answer, as long as there is electricity,there is safety hazard,
Q:Which is better for ceramic film and silk film high pitched voice?
Each has its own advantages. Silk film quality is delicate and soft, you won't be tired for long time listening, more suitable for the appreciation of light music, classical music, folk songs etc., but the bear power is not, generally used for home or personal audio system. The titanium film is clear and transparent, it is suitable to enjoy some symphony, popular songs or DJ dance music, but also bear the power, so the general performance environment, more and more songs and dances. But the treble is too powerful, large volume and long time appreciation will make people feel tired and irritable.
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 are the differences of seepage-proof geomembrane and polypropylene fiber impervious geotextile?
The seepage-proof geomembrane is made of high density polyethylene by flat extrusion or blow molding. The white seepage-proof geomembrane is heated and covered with polypropylene fiber geotextile top and bottom which finally becomes polypropylene fiber impervious geotextile. It has a good extensibility and environmental resistance as well as better anti-seepage effect. The seepage-proof geomembrane is usually black or white HDPE.
