Q:The service life period of geomembrane
Because the composite geomembrane has oxidation resistance, some files in some companies extend the time limit the previous Soviet Union BCH07-74 "Notice for the earth-rockfill application of polyethylene dam seepage control structure" stipulates polyethylene geomembrane can be used for buildings with limit over 50 Ollie Linz company publish papers on polypropylene composite geo-membrane geotechnique composite material character, whose conclusion is: Polypropylene 15 on-site application experience shows that the compound has high stability; fabric damage construction; laying has no change;...... Expected to exceed 100 stability diagram"
Q:How to tear down the computer film?
As far as I know, the method to remove the computer film is: General protective film has more than one layer, so you can pry one side of the well-sticked protective film from a corner of the screen with a layer of film which is not to be used, and then pull the film with your hand. If you want to continue to use the protective film, pay attention not to touch the sticky surface of the protective film with your fingers, or it will be sticked with fingerprints which are difficult to remove, affecting the vision after being sticked up. The above is my personal experience,
Q:Does geomembrane has the color of grey?
Polyethylene geomembrane, for example, polyethylene is colorless, but in order to improve the UV resistance of the geomembrane, we usually add carbon black particles, then geomembrane will turn black, and is completely black, after cutting fracture, you will see the complete blackness.Generally, geomembraneare all black. Other colors, such as gray, white, green is formed due to addition of color of coating on black film. There is a certain function, for example, white can reflect lights, drop rising temperature caused by the heat absorption; green film can be used as seal field, more beautiful than a large appearance of darkness.
Q:Geomembrane snz/ pvc-12-400-0.35 model
(there is no manufacturer can produce 12m wide geomembrane at present) if it is SN/PVC-1, using 400g/ ㎡ polyester staple fiber geotextile and 0.35,another possibility is that your product model is wrong At the same time, according to national standard GB/T17642-2008. Combine 35mm thick PVC geomembrane together, using 400g/㎡ polyester staple fiber geotextile and 0. If this is geotechnical material used for seepage-proofing in the projects,
Q:How to deal with the bubbles in the mobile phone film?
If there are bubble in the mobile phone film, please use hard bank card or other cards to gently squeeze out the bubbles from intermediate network edge and surroundding. The process should be slowly, you don't be impatient, and pay attention to not crumble the big bubble. You shouls spend a relatively long time to scrape the bubble to the edge, and then squeeze out the bubble. At last, mobile phone film is perfect and flawless. if there is dust in the mobile phone film, it is more difficult to solve than the bubbles, this film is possibly destroyed , because it represents that you live in a dirty environment, the suspended solids in the air are too much, where is not suitable for sticking film.
Q:JS waterproof, SBS, SBC, PVC, geomembrane, what are the disadvantages of these waterproof materials?
Geomembrane is not suitable to be in complex pipeline project and constructions. SBS adopts hot melting construction; SBSJS waterproof coating cannot be constructed in below freezing and rainy days, PVC, and the film will need some time to dry, which is not suitable for waterproofing roof. The construction of SBC is complex.
Q:What's the function of the base membrane of wall cloth?
It can prevent fungal growth, better plays the role of linking the wallpaper with the base, and is convenient for secondary pasting.
Q:How to stick membrane on the cabinet?
First of all, clean the surface of the cabinet. The 75%vol medicinal alcohol is recommended because it is easy to clean and dries rapidly. Then measure the size of the area where you want to stick membrane and tailor the membrane you bought according to the size. To avoid waste, a draft is recommended. Finally, stick the membrane from up to down gradually and check at all times to prevent the membrane from being slantways stuck. It is really a great trouble to deal with the membrane slantways stuck.
Q:Does anyone know the mechanism of ion exchange membrane
the mechanism are as follows: Ion exchange resins are high molecular material with an ion exchange function. in the solution, the ion of itself will have an exchange with the ion which has the same symbol in the solution. According to the different nature of the exchange groups, the ion exchange resin can be divided into cation exchange resin and an anion exchange resin. Most of the cation exchange resin has a sulfonic acid group (-SO3H), carboxyl (-COOH) and phenol (-C6H4OH) and other acidic group, wherein the hydrogen ions in solution can have an exchange with a metal or other cation. For example, the polymers of styrene and divinylbenzene by sulfonation is giving strong acid cation exchange resin and the structure can be simply expressed as R-SO3H, wherein R represents a resin matrix, the exchange mechanism is 2R-SO3H + Ca2 + (R-SO3 ) 2Ca + 2H this is the mechanism of water softening. Anion exchange resin comprises quaternary amine [-N (CH3) 3OH], amino (-NH2 ) or imidogen (-NH2 ) and other alkaline group. They can generate OH- ions in the water, and have exchange interaction with a variety of anions, the exchange mechanism is R-N (CH3) 3OH + Cl- R-N (CH3) 3Cl + OH- due to the ion exchange is reversible, so the used ion exchange resin is suitable to wash with acid or base resin with a suitable ion exchange concentration, to restore the original state and repeated use, so the process is called regeneration. cation exchange resin can be washed with dilute hydrochloric acid, dilute sulfuric acid solution; the anion exchange resin can be treated with sodium hydroxide solution, etc., and then reproduced. ion exchange resins are widely used, and it is mainly for the isolation and refinement. For example, softening water system and producing deionized water, recycling metal in industrial wastewater, separating rare metals and precious metals separation and purification of antibiotics.
Q:what is the role that Imported HDPE geomembrane plays in impermeable reservoir bottom system in the landfill.
Basically no use.
