Waterproof Geomembrane/Liner/ Sheet with China Top Quality

Q:How do geomembranes prevent soil contamination?: Geomembranes prevent soil contamination by providing a barrier between the soil and any potentially harmful substances. They are impermeable liners that prevent the migration of pollutants, such as chemicals or leachate, from reaching the soil. This protective layer ensures that the soil remains free from contamination, thereby safeguarding its quality and preventing potential environmental hazards.

Q:What is the temperature of PET high temperature resistant film?: high temperature resistant polyester film. It has excellent physical properties, chemical properties and dimensional stability, light transmittance and can be recycled. Cold resistance (--70 degrees), heat resistant ( 200 degrees), and has the good characteristics of corrosion resistance and shrinkage stability. High temperature resistance performance of protective films varies with the material of the film. PE electrostatic film is generally resistant to temperature of 60 degrees. PE high temperature resistant plastic is generally resistant to temperature of 120 degrees, and PET is 60 degrees -230 degrees theoretically, the actual situation remains to be customized and tested.

Q:How to remove the plastic film on ceramic tiles?: 1) The plastic film can be teared off gradually by hand, wiped by steel wool gently or teared off after heated by air heater. 2) anti-fouling agent packaging film can be wiped by towel with white cement. 3) Wax packaging film can be wiped by dry towel, banana oil, or talcum powder with white cement.

Q:Hdpe film why not in winter construction: Minus 5 degrees above can be, I professional production geomembrane

Q:Can geomembranes be used in underground construction projects?: Yes, geomembranes can be used in underground construction projects. They are often used as a barrier to prevent the migration of liquids or gases, such as water or contaminants, in tunnels, basements, and underground storage facilities. Geomembranes provide a waterproof and durable solution to protect structures from potential leaks or damage.

Q:How do geomembranes contribute to erosion control on slopes?: Geomembranes contribute to erosion control on slopes by acting as a barrier against water and preventing soil particles from being washed away. They provide a protective layer that reduces the impact of rainfall, minimizes surface runoff, and helps to stabilize the slope. This helps in retaining the soil in place, reducing erosion, and increasing the overall stability of the slope.

Q:Can geomembranes be used in floating covers for liquid containment?: Yes, geomembranes can indeed be used in floating covers for liquid containment. Geomembranes, which are impermeable synthetic liners, are commonly used in various environmental applications, including floating covers for liquid containment. These covers are designed to prevent evaporation, contamination, and the release of gases from liquid storage systems such as ponds, lagoons, or tanks. The floating cover, made of a geomembrane material, floats on the liquid surface and provides a secure barrier, ensuring the containment and protection of the liquid.

Q:Which is better for ceramic film and silk film high pitched voice?: Advantage of silk film: Delicate and soft defects: The upper limit is too low to be less metal than the ceramic film: High sensitivity limit high transparent clear shortcomings: Metal feeling strong, easy piercing now in the high-end speakers generally use the five frequency design: Titanium film treble silk membrane treble bass baritone bass treble two complement each other and enhance limit is not critical

Q:can the national standard quality of composite geo-membrane be used for geotextile?: no. composite geomembrane and geotextile are two different products, their function is not the same. Non-woven geotextile is woven into nets with long silk or short silk through different equipments ans technology, needling technology will make different fibers interwoven together, interwoven them and make the fabric standardization, making the fabric soft, rich, thick, hard to make different thickness satisfy the usage requiremants, non-woven geotextile has good fabric gaps and adhesive force, fibers are soft and has tear-resistance performance, also good deformation adaptability, good surface dewatering, it's surface is soft and multi-gap, also good friction coefficient, which will increase the adhesive force of soi particles, it can prevent little particles, losing surplus water while preventing the loss of particles, soft surface has good protective ability. it is divided into long fiber nonwoven geotextile filament or staple fiber nonwoven geotextile in accordance with the length, They can play a very good filtering, isolation, reinforcement, protection function and is a kind of widely used geosynthetics material.

Q:what's the function of coated paper board ?: General packaging which you tounched smoothly is used the laminated paper board, and on the surface it has packaging film, however, food, gifts, wine boxes and other packaging is flat, smooth, and not easy to fade, and waterproof.
