- Q:what's the items needed to be noticed in the pavement of composite geo-membrane?
- Avoid stones, bricks and hard objects, geomembrane construction can be fixed submerged. Avoid uneven subsidence. 3, to avoid sharp objects hurt, can also be used with anchor nail 1, the roots should be cleared, laying the ground for a smooth, while laying flat at best or bottom of the embankment to accommodate the deformation of the matrix: 6, according to different circumstances, pull hard, without stones, pulling should be avoid when paving composite geo-membrane, the joints of composite geo-membrane should avoid side slope, and leave certain stretching and cracks.
- Q:How do geomembranes perform in underground mining operations?
- Geomembranes are highly effective in underground mining operations due to their ability to provide reliable containment and barrier systems. They are utilized to prevent the escape of harmful substances, such as contaminants and liquids, into the surrounding environment. This helps to protect both the workers and the ecosystem from potential hazards. Additionally, geomembranes are resistant to punctures and have a high tensile strength, making them ideal for use in rugged mining conditions.
- Q:Geomembrane's features
- Width 6 meters wide composite film has high puncture-resistant strength and anti-friction coefficient, it can adapt to the ambient temperature range and has superior anti-drainage, it's applied in water?conservancy, chemical engineering, construction, transportation, iron, tunnels, waste disposal sites, etc.
- Q:What is the DIY method of sticking the film?
- It depends on what you need. If you need a simple pattern, you can buy the mobile phone shell material; if you need the silk screen pattern with the diamond, you can buy some crystal material, they are pasted on the mobile phone shell in accordance with your own ideas. Some people use the bamboo chopsticks to do the mobile phone shell. There is a lot of methods.
- Q:Which one has lower cost between geomembrane and composite geomembrane?
- The cost of geomembrane of equal weight is higher than that of composite geomembrane, geomembrane texture HDPE, composite geomembrane texture LDPE+PET, the current market price HDPElDPE difference, PET is cheaper than HDPE
- Q:Can geomembranes be used in irrigation canal linings?
- Yes, geomembranes can be used in irrigation canal linings. They are often chosen for their ability to prevent water seepage, enhance water conservation, and provide a durable and long-lasting lining solution for irrigation canals. Geomembranes effectively reduce water loss through seepage, leading to improved efficiency and effectiveness of irrigation systems.
- Q:What kind of membrane switch material is good?
- Most mask material of the membrane switch is of polyester material, mainly including polyvinyl chloride (PVC), polycarbonate (PC), and polyester (PET). These three kinds of material all have their own advantages and disadvantages, and you can choose from them according to your own needs. For instance: Its flex life, resistance to chemical corrosion, abrasion resistance, insulating property, window transparency, articulation, temperature class, and UV resistance can be used as reference data for selection. As to how to make a distinction between the plastic film and plastic sheet, there is a lack of uniform standard by now. It can be classified into film, sheet and plate according to the difference of thickness. As defined by the German standard DIN55405, the material with the thickness of less than 1.5mm is called membrane, while the material with the thickness of more than 1.5mm is called sheet. In our country, as a usual practice, the material with the thickness of 0.3mm or less than 0.3mm is called membrane, the material with the thickness of 0.3-0.7mm is called sheet, and the material with the thickness of more than 0.8mm is called plate. Since the general used thickness is limited in the nameplate production process, thin film and membrane are collectively called membrane.
- Q:What kind of mobile phone stick membrane is good?
- At present, the mobile phone beauty in mobile phone stick membrane mainly has four kinds of material: PP material, PVC material, PET material, arm material. PP material stick membrane is soft, and the translucency is also poor and it does not have the function of anti-scratch, anti abrasion, it can only prevent dust, since the result is not good, now it is basically abandoned by consumers. PVC material stick membrane is soft and easy to paste, but it is relatively thick, and the transparent performance is not very good. And if you tear the stick membrane, it may leave a defective gum on the mobile phone screen, affecting the appearance. stick membrane of PET material has high transmittance, leaving no defective gum on the screen after tearing, and it will not appear the small bubble in the middle of stick membrane. But the stick membrane reflection is a little higher, so that the users can't see the words on the screen, and easy to leave fingerprint on the surface, etc. Arm material, the membrane surface of this material is processed by the latest technology, having the ability of wear-resistant and scratch resistant. At the same time, this material has no bubble after pasting, and the light transmission is also very good, after tearing it will not leave any traces. Relatively speaking, the effect of this membrane is the best, and the price is the most expensive.
- Q:How do geomembranes handle settlement?
- Geomembranes handle settlement by being flexible and able to conform to changes in the underlying terrain. They can stretch and move with the ground, minimizing the risk of tearing or damage. Additionally, geomembranes are often designed with reinforcement materials to enhance their resistance to settlement. Overall, geomembranes are engineered to accommodate settlement and ensure long-term stability and performance.
- Q:How to judge the quality of geomembrane?
- If there is no professional testing equipment, the following ways of identification can be used, can resist most of the plant roots. 3: 1, has excellent anti-puncture ability. Good geomembrane elongation 4, decomposition resistance capacity, and then draw back with efforts. Bad one has no lustre, glossy, cut 5 cm wide strips on geomembrane, can be barely used. visual inspection. Good geomembrane is black and bright, bad geomembrane is easy to crack. Repeatedly rub, tensile testing, the materials service life is up to 30-70 years, anti ultraviolet. 2. Good geomembrane will not crack if repeatedly rubbed, good geomembrane has excellent anti-aging property. 5 times will not break
