- Q:the seepage-proof pavement of composite geomembrane.
- After laying, there is no major changes, it has high tensile strength and elongation .9m, paving, two cloth one film. after waving and combination.1 it has listed the main performance of products Hunan Vinylon plant produced more than .5 indicators. ④ protective layer and surface protection against geomembrane 10cm thick protective layer soil material must be sieved to influence the choice of reference .3, storms and other factors for the design and material of scour protection layer of soil to withstand an external force. Domestic and international application of impermeable plastic film. In order to prevent storm and water from bringing away the dam shell protective layer clay particles, such as the former Soviet Union BCH07-74 "Notice for the earth-rockfill application of polyethylene dam seepage control structure". Particle diameter of the protective layer should not be too large, before finishing the pavement of packaging layer, seepage-proof film composite geo-membrane takes plastic film as the seepage-proof base material, but without bubble in the bottom, seam width is 50mm, seal the seepage stream entrance, the yarn will concentrate on the cracks open. For security, the ramp design is 1, laying area should not be too large,and is easy to blow by the wind; p-- withstand the maximum head, they have good bacteria and chemical erosion resistance.
- Q:Does iphone need to stick membrane?
- If iPhone do not stick membrane, it will be scratched by some alloy keys; and it will have minor scratches because of the friction with ordinary sand. Mobile phone film will inevitably reduce the screen brightness. First, reduce the screen brightness. Even it is the AR film (also known as high light transmittance anti-reflection film) featured as high light transmittance, its light transmittance is only about 95%. Other mobile phone films have greater influence on screen brightness. Second, reduce trackpad sensitivity. After sticking membrane for mobile phone, the screen may become "stuck", "slippery action", thus reduceing the iPhone's touch experience.
- Q:How to remove the adhesive film?
- The method is as follows: To cut a corner of the glass with the knife. Take the baking gun while baking it, slower, or not complete. Tear off, spray the reactive foam cleaning agent on the glass, and wait for a few minutes. Then spray some water and scrape it off with a blade. In fact, the glue will be peeled off with a bottle of water to wash away.
- Q:How to use geosynthetics impervious device?
- The geosynthetics impervious device is designed according to national standard of permeability coefficient. It is applied to test seepage resistance of all kinds of geosynthetics. It is convenient and practical with stable performance.
Installation and use methods are as follows.
1. Set pressure. Press the set button "back" and the button "＞" after powering on the device. Press the button “+”and“--”, then set pressure. After that press the button "back" to save it. After setting the lower limit value, press the set button to exit.
2. Clear the time setting. Redo the test and continue pressing the "--" button. The time value will be reset to 0 after 10 seconds. Don't press the button during the working time.
3. Check the time. Press the "--" button. The time value accurate to seconds will be shown on the screen. After 30 seconds, pressure value will be shown on the screen again.
4. Adjust to zero. If the pressure setting can't return to zero when the device is powered on without being applied pressure, you can press the reset button once. If the device is under pressure, release the pressure before pressing the button.
5. Open water injection cover plate. Add pure water until the water tank is full. Apply pressure and open pressure regulating valve to let water flow to chassis of high pressure cabin until the water begins to overflow.
6. Put the sample on the net plane of water collectormanifold smoothly. Let the excess water drain away to ensure that there are no bubbles in sample clamping device. Close the perforated plate and fix the sample evenly.
- Q:What are the principles of diaphragm pump?
- Diaphragm pump, also known as the control pump, is the main type of actuator, changing fluid flow by means of power operation by accepting control signal output from modulation unit. Diaphragm pumps are generally composed of the actuator and valve. Using compressed air as power, it can pump and absorb all kinds of corrosive liquid, liquid with particles, high viscosity, volatile, flammable, highly toxic liquid.
- Q:Is the mobile phone laminator useful
- Mobile phone laminator is very useful, from the hauling of actuating device to the stripper plate under the intaking device, under the gulidline of autohension, after a series of tensioning guide device were sent to be peeled, and then adjusted by the automatic manipulator. It is automatically posted to the positioning workpiece.
- Q:What are the functions of uv matt lamination gloss oil?
- Uv matt lamination gloss oil, a synthetic resin, usually refers to the varnish with transparent surface. It is made of binder and additives without any pigment, and it glisten after filming. It is also known as matt lamination varnish. Function 1. Transparent protective lacquer whose hardness and wear-resistant properties are better than colored paint, which can play a protective role. 2, Hand feeling paint has good luminosity and brightness, and it feels good.
- Q:Is it good to use wall decoration film when decorating the house?
- It is good. Pinup pictures that is made of the environmental protection material of PVC is waterproof. Different from traditional hand-painted wall, wall stickers do not need to be painted by yourself. Instead, various patterns have been designed. You only need to uncover the protective film and paste it. You can customize different colors and sizes according to the home style. There are particular stickers for kitchen, bathroom, bedroom, corner of wall and living room and these wall stickers can also be exchanged. Wall stickers will not fall off within five years.
- Q:What is the material of the installation technology of soft membrane?
- It is made of special PVC materials without cadmium and the fire rating of B1. There is a very good fire performance.
- Q:What are the requirements of geomembrane waterproofing construction for the base?
- Level compaction, sharp object namely
high-geo, is specialized in the production of glass fiber chopped strand mat, woven roving, stitch mat, geogrids, and other fiberglass products business. We possess 10 advanced chopped strand mat production line and also manufacture alkali, alkali injection yarn, direct yarn, winding yarn, surface mat, fiberglass mesh cloth, and other products.
