What is the difference between the primer and the basilemma?
- The main difference is as follows.Primer is used as back cover. Basilemma can be used as back cover as well as interface agent which can increase the adhesion of sublayer and surface layers.Besides, primer often contains formaldehyde, some of them can even release the formaldehyde (materials containing formaldehyde used on outer wall are not forbidden by national standard). However, quality products of primer are environmental friendly and odorless. So it's better to choose primer as wallpaper.s
What kind of geomembrane does the channelanti-seepage film use?
- The channel seepage control is generally used in composite geotechnical membrane in a cloth a film specifications such as 200. The great subjects, like The South-to-north Water Diversion Project took use of the 150/0 two cloths film one film of the polyester filament anti-sticking composite geo-membrane.s
What's the principle of diaphragm valve?
- Principle: Power drive screw with compressed air to make valve element move up and down and pull mebrane up and down movement to turn it off and on. Features: compact, simple, small, beautiful; switch with guide, smooth motion; little closing moment, long life, ≥30 million times; mebrane compaction can be automatically adjusted for uniform pressure and reliable sealing; install mebrane into valve element through pushing-in method which is easy to replace.s
How to stick the film without the bubbles
- Without the bubbles: 1, to select the good quality of film, good film has wear resistance and high transparency, the rubber-faced is even without the bubbles. 2, The cell phone screen is cleaned up with clean cotton cloth which does not epilate, do not stay the dead angle. 3, when sticking the film, the phone is fixed, and then uncover the protective film of the film, but not uncover the all of the film, only a third of it. The uncovered film is aligned at the top of the mobile phone screen in the left and right, and gently put up and adjust the position. After the film is pasted, you should use the towel cloth or cell specific towel to slowly wipe from the top to the bottom in order to make it fully bind. And then, you gently uncover the 1/2 film pellicle, the next operation is same to the above until the entire process is completed.s
How does the soft film ceiling?
- I think the the family decorative use is also quite good. No matter how popular it is, the gypsum board is also used by a lot of people. The domestic board is generally transparent, and the foreigners like smooth and the price is not the same.s
How to separate the non woven fabric from the waterproof board?
- Installation and construction of HDPE geomembrane shall be in accordance with the specific site condition and climatic conditions, properly pre-place 2%-5% extension volume; level surface mounting of base, remove the roots, stones and other sharp objects; trim round internal and external corners with its fillet radius equal to or more than 50cm; welding seam surface must be clean; welding seam should adopt displacement installation to avoid cross-wire welding, T-shape installation is available; using the side ditch anchoring landfill or bead seal installation; welding uses double track thermal melting, monorail hot melt, squeezing welding rod welding; seam take junction width is 10cm-15cm.s
How to calculate the power consumption of the electric heating film?
- To measure the DC resistance and square the rated voltage divided by the DC resistance, then the power is calculated. The electric heating film is divided into high temperature and low temperature electric heating film. The high temperature electric heating film is generally used in electronic, military and so on. The electrothermal film produced by the Today Technology. The low temperature electric film is a semitransparent polyester film after it is powered. It is made of by the special conductive ink. It is processed by the metal carrier and made between the insulating polyester film. When working, it takes the electrothermal film as the heating element and sends heat into the space in the form of radiation. It can first make people's body and the objects to get the heat. It's integrated effect is far better than the traditional method of convection heating. The low-temperature radiant electric heating film system is composed of a power supply, a temperature controller, a connecting piece, an insulating layer, an electric heating film and a facing layer. The power supply is connected with an electric heating film through a conducting wire, and the electric energy is converted into heat energy. Because the electric heating film is a pure resistance circuit, the conversion efficiency is high, in addition to a small partial loss (2%), the vast majority (98%) is converted into heat energy. The electrothermal membrane can not be directly for the radiant floor heating, requiring additional patent PVC vacuum envelope, it can be used in floor heating to ensure the use of effects and life. The development potential of electric heating film is huge, which is consistent with the trend of low carbon economy development.s
Which kind of mobile phone screen protector is better, frosted film or transparent film?
- The transparent film is clear with good transmission, but it is easy to leave fingerprints, which make you have an unsmooth feeling when you use the phone. The hand feeling of frosted film is very good, it basically not leave fingerprints, but the definition is not good enough, it looks a bit fuzzy. In private opinions, if you want to clear but do not want to leave too many fingerprints, you can choose HD fingerprint-proof film, it is relatively easier to clean some of the fingerprint. But it is impossible to completely eliminate, including toughened glass film can not be completely eliminated.s
