Q:What is a coated glass?
Coated glass is coated one or more layers of metal, alloy or metal compound thin film on the surface of the glass so as to change the optical properties of the glass and meet certain requirements. It is mainly used in construction, automotive, decoration and other fields.
Q:Is there any place seeling the geomembrane of 20 multiplying 20?
The 20 * 20 should refers to the length and width of the geomembrane.
Q:How to stick the film on the bathroom window?
The first step: You should measure the size of the glass.The size of the film should match that of the window, in case of wasting the film. Next if you want the film to be perfectly stuck, then you must spray some water to reduce the dust befor sticking the film, creating a dustfree environment for the film. The second step: Before finhishing washing the glass, you should put a lint free towel under the window to be washed to prevent water from flowing to the outside, thus soaking walls. Cleaning the glass is a important step and it relates to the effect of the film. The third step: When sticking the film, you should spray some water on the both side of the film to remove attachments on the film attched by the static electricity. Then, you can tear off the plastci film on the glass film, spary water on it and stick it on the glass. After that, you can squeeze the the water out and cut needless edges. The fourth step: The final step is to check whether the film has been stuck well. You can check whether edges are firmly attached and whether there are bubbles and wrinkles. Only when it is certain that there is no problem with the film the process of sticking film has been complished.
Q:Does the showering room membrane need to be pasted?
you can choose stick membrane as the bathroom film. Now the bathroom glass is tempered glass, if broken, it will not hurt anyone. sticking membrane is just to prevent glass accidental broken and the single piece of glass is unbroken. It will not fall off. The film also has a beautiful effect, because on the film it can be printed flower or other patterns.
Q:How to tear down polarizing film from display?
Processes of tearing down polarizing film from display: We need a few high-quality blades, bamboo sticks, absorbent cotton and a little alcohol. After the screen is torn apart, take down the back shroud, the screen can be just put in the frame and needn't to be put out, and lay it on the table flatwise. Viewing screen corner, you will find that at the gluing between edge and glass, cut along glass with a blade, use tweezers lift cut polarizing film, and take a absorbent cotton bamboo stick to dips a little alcohol and swipe at the cut gap, the polarizing film will slowly separate from the glass till completely peeled off. You can also use water, but you have to prevent the water from flowing to the back panel. After peeling off polarizing film, the adhesive residue on the glass screen should be cleaned up.
Q:can geomembrane reach A-class seepage-proof?
the seepage-proof effect of project composite geo-membrane is mainly depends on the interlayer, the norms of seepage-proof geomembrane is 100-1500g/square meter, in order to guarantee the good seepage-proof effect, the thickness of geomembrane should be less than 500g/ square meter, outer geotextile should be less than 300g, too thin geotextile will reduce the sand stone resisting effect, increasing geomembrane's thickness and prevent sand stone corrosion will influence the seepage-proof effect of geomembrane, composite geo-membrane's norms is less than 800g/square meter, which can reach the seepage-proof standard.
Q:What is the meaning of pe50-3-200 for water geomembrane
Thickness and weight, specializing in the production of pe geomembrane manufacturers to answer,
Q:Which is better, oil heater or electrothermal film
Electric heater is also called electric heater with oil charge. The electric heater is filled with a new type of heat conducting oil, when the power supply is switched on, the heat conducting oil around the electric heating tube is heated, and then the heat is distributed along the heat pipe or the scattered piece. electrothermal film electric heater uses all transparent high temperature electrothermal film as the heating material, it is the advanced level in the process in the world.
Q:why is the lateral welding edge of composite geo-membrane so dim?
genrally, the four edges of composite geo-membrane produced by factory is left with 10 cm welding edge for the welding of composite geo-membrane. customers can confirm whether the composite geo-membrane is produced by new materials through the left welding edges, the new material is bright and transparent, but the reused edge is dim and yellow. two producing technologies of composite geo-membrane: pressed laminating technology and composite technology. composite geo-membrane's welding edge produced by rolling lamination process is generally smooth and bright, but the composite geo-membrane produced by composite technology is wrinkle and lacks of lights.both two can reach the standards, GB/T17642-2008, composite geo-membrane users can choose the raw materials bby themselves.
Q:What is the installation technology of soft membrane?
When installing the soft membrane, the first is to install the four angles of A, B, C, D, then the diagonal pull point installation, finally all installation. The installation sequence: 1. Before the entering of the soft film smallpox, the site must be electrified and without construction waste. 2. The deal with the bottom of the piamater ceiling should be fit for the installation conditions, such as the installation of the steel and so on; it must be cleaned. 3. All the installation of the lights must be according to the requirement of us. We should ensure all of the circuit to be electrified. If there are any lamp not lighting up before installing the soft film, it should be adjusted and repaced in time. The interior hidden lights should be painted with white paints so as to get a better effect. 4. The air conditioning and fire pipes must be arranged in advance and debug to keep it operating well. After the installation of the air inlet, spray head, and smoke sensor, all of them should meet the requirements of us. 5. After the installation of the piamater ceiling is completed, for example, the paint should repair the gypsum board and should not touch the soft film smallpox.
