Q:How do use geomembrane to prevent sewage seepage?
Q:How is the oil film on the fish tank produced?
The environment of fish tank is the same with the sea. When it is contaminated or the self-renewal ability reduces (for example when the water is seldom changed), water will be eutrophication. Besides, sunshine is plenty and green algae overgrowths, which will consume a large amount of dissolved oxygen in water. This is the principle of green tide.
Q:How to install the electric heating film?
1 The most scientific way to install the electrothermal film is to install it in the ground. In light of heat transfer theory, this is the best heating mode. From the perspective of health maintenance, the heat is flowing from the bottom to the top, which meets the physiological needs that foot is warm and head is cool. Installing the electrothermal membrane in the ground can not only make people feel comfortable, and also can increase the usable floor area of space and guarantee the even temperature all over the area. However, because each family has different pattern and furniture is displayed differently, the limited space and degree of difficulty should be considered when designing the installation to ensure that there is no barrier in the installation process, make the electrothermal film heating system more safe and reasonable and reduce the cost of expenditure. Main structures are floorslab or floor, heat insulating layer, electrothermal film, structure layer and the decorative layer. The composite thermal resistance of structure layer and the decorative layer should be lower than the standard value. 2 There are several ways to calculate the amout of the electrothermal film for gound installation. 1 Calculating the thermal load. You can first calculate the thermal power of each room and convert it into wattage of electrothermal film. Calculation of the heat load should be carried out by professionals. This method can be applied to large projects. 2 Empirical method. According to the conditions of the room, you can estimate the heat load of the room. This method is generally used for single family transformation project. 3. Fully paving method. When it is required that the whole area should be heated, the heat loading value can be ignored and areas which has human activities should be fully paved with the film. This method may increase the cost of pavement, but will not affect the operating cost.
Q:How to remove the adhesive film?
1. The vinegar clean method. To homogeneously smear the vinegar on the adhesive sticker with the cotton swab, and wait it to spread, use the cotton swab scratch it to and from and then the adhesive sticker will peel off. 2. The essential balm method To smear the essential balm on the adhesive sticker and use the cotton swab to scratch, the adhesive sticker will peel of in two mimutes. 3. The alcohol clean method. To brush the alcohol on the adhesive sticker, it will become softe and will be peeled off clearly by your finger.
Q:Is lectric heating film electric heater electricity-saving
It depends on two factors, one is the electric heat conversion efficiency, the two is the power. The high the electric heating conversion efficiency, the less electricity it consumes. Well, if we understand this we can analyze whether our household appliances consumes electricity. Power is a fixed value, which is fixed before we buy. For example, we buy a electrothermal film heater whose power is 2000W. This means that the heater consumes 2 kwh of electricity per hour, which is 2 degrees, if it is 1500W, that is 1.5 degrees Electric per hour. The electrothermal conversion efficiency is to consume things unease to know, but we can generally analyze like so: The process of heating is a process that transfers electric energy into heat energy, so we would hope that electrothermal conversion efficiency be higher if we want to get maximum heat. According to the law of conservation of energy, the greatest possibility is 100% conversion. But in fact, the conversion of electric energy into heat energy also includes the conversion into light, (such as small solar heating, which is also luminous in the the moment of heating, a lot of power is converted into the energy we don't need, so the conversion efficiency is low, magnetic energy and other energy. Therefore, in general, the electrothermal conversion efficiency of most heating body is almost the same in the current market, the transfer efficiency of heat body that is not luminous is higher than those giving out lights.
Q:What is the role of the base film
The role of the base film is cured to protect the wall, the wall is equivalent to stick a protective film which is a water-based environmentally friendly materials, tasteless, non-toxic, no side effects on the human body, and now the wallpaper has to be brushed before pasting.
Q:How to choose and buy the laminating machine.
How to select the hot film laminating machine, the classification of coating machine: including sizing treatment, drying, hot pressing three parts, the scope of its wide application, stable and reliable processing performance. The pre-coated laminating machine: There is not the part of supreme adhesive and drying part. The volume is small. The operation is flexible and convenient, which is not only suitable for large quantities of printing products, film processing, but also for desktop automation office system, small batch, scattered printed film processing. Single roll: The film only with two of double roller pressure roller: The film are with four pressure rollers. One side: The film can only be coated on the surface of the product, and the conventional point on the surface. The double: The product can be covered with plastic film, and the conventional point of the upper and lower surfaces. The material received: For the label with release paper, the protective film or 3M film and other products, it need to peel away from the type of paper before laminating and recycling. One single transport: For the single plane import rollers conveyor belt. Double transport: The plane double rollers import conveyor belt. The heating film: The special hot film in the heating to a certain temperature (about in the 100-180 DEG C) equipment for mounting method called thermal laminating can be divided into single-sided hot laminating and double-sided heat mounted, because of the light penetration and watertightness good, good heat resistance, high hardness for to light for later rely on other occasions the advertising picture making.
Q:What are the precautions for the construction of the slope area of the cesspit?
The construction method of geotextile/geomembrane: 1 flatness: ±2cm/m2, flat and straight; 2 compactness: 95%, after grinding, pave geomembrane on the surface; 3 vertical and horizontal gradient: Longitudinal and transverse slope should be above 2%, boundary and structure of the landfill bottom must be beneficial to diversion of leachate; 4 cleanness: No roots, rubble, gravel, concrete particles, such as sharp edges shall appear within vertical depth of 2.50cm . Climate requirements while paving: 1. Temperature: 5 - 40℃ is appropriate. Taking into account thermal expansion and cold contraction of the geomembrane, according to experience, when the weather is cold, geomembrane pavement should be tight; in hot weather should be loose; but it should be noted that, in summer, high temperature should be avoided at noon. 2 wind and rain: If the wind scale is over force 4 wind or it's raining, the construction should be stopped; When wind is lessened, it is proper to hold down geomembrane with sandbag so as to facilitate construction. Construction and installation of HDPE geomembrane: 1 construction and installation process of HDPE geomembrane. 2 tailor and transportation: According to the records of laying base measurement , cutting large bundle number of geomembrane should be marked and recorded and then carried to construction site according to their number.
Q:What are the differences of geotextiles and geogrids?
Geogrids can be used to reinforce the soil mass and improve the integrity just like the reinforcing bar in concrete. Geotextiles can be used in seepage control engineering. I have place the multilayer non-woven geotextiles and geomembranes on the rubbish dam and anchoring platform of a refuse landfill. There are some tips about geotextiles. Geotextiles can be divided into two categories, namely the impervious geotextile and permeable geotextile. Geomembranes and impervious geotextiles can be used to prevent emission of the ground water caused by capillarity. Geotextiles are porous to liquid but soil can't go through them. For example, they are used on the surface of supporting sewers of high slopes and in the roadbeds above water level (water in roadbeds can freely diffuse through the permeable geotextile just as in the roadbed blind ditches).
Q:What is the seepage-proof geomembrane?
Co-extrusion technology is used during the production, the main material of it is high density polyethylene native resin with high quality. It has a low hydraulic permeability and excellent seepage-proof performance. The standard name of HDPE seepage-proof membrane is polyethylene geomembrane, which has a highly efficient molecular density.
