Q: What are the differences between the geomembrane and geotextile?: To put it simply, geomembrane is impermeable to water, while geotextile is permeable to water. Geotextile is made of nonwoven fabric, mainly used to consolidated subsoil. Geomembrane is made of high density polyethylene, mainly used for seepage-proofing. Geotextile can be divided into woven geotextile and non-woven geotextile, which has excellent functions like filtration, drainage, separation, reinforcement, seepage-proofing, protection and characteristics like light weight, high tensile strength, good permeability, high temperature resistance,anti-freezing, aging resistance and corrosion resistance. Geomembrane is a kind of polymer chemistry flexible material taking plastic film as seepage-proof substrate, with small proportion, strong extensibility, high?adaptability?to the?deformation, corrosion resistance, low temperature resistance and good anti-frost?property. Geomembrane is mainly used for projects in engineering construction field which have high seepage-proof requirement like seepage-proofing, isolation, enhancement, anti-cracking, reinforcement, water drainage in horizontal plane. "Geotextile is used for anti-filtering while geomembrane is used for seepage-proofing." Geotextile and geomembrane can be used alone and they can also be combined into one to give play to their respective strengths.

Q: Can geomembranes be used for gas containment?: Yes, geomembranes can be used for gas containment.

Q: Electrothermal?film heating system and water heating system, which one is better?: Generally electrothermal?film is better than water heating. Water heating system has too many problems, such as running, leakage and dripping, it also takes up place, and costs a lot. The electrothermal film heating has a independent switch and long service life, is energy saving, material saving, land saving, water saving and very convenient.

Q: What exactly is the geomembrane? What are the applications?: At the same time, alkali and salt corrosion, long service life; and non-woven fabric is also a kind of high-molecule short fiber chemical material. Geomembrane construction site its main mechanism is to use imperviousness of plastic film to cut off earth dam leakage passage, not only increases the tensile strength and anti-puncture ability of plastic film. They have good corrosion resistance to bacteria and chemical action, which is conducive to the stability of composite geomembrane and protective layer, with high tensile strength and extensibility, bearing the hydraulic?pressure and adapting to dam deformation with its large tensile strength and ductility, increasing the friction coefficient of the contact surface. And due to the roughness of the non-woven surface, geomembrane construction site its main mechanism is to use imperviousness of plastic film to cut off earth dam leakage passage; and non-woven fabric is also a kind of high-molecule short fiber chemical material, bearing the hydraulic?pressure and adapting to dam deformation with its large tensile strength and ductility, through needle punching or hot sticking forming, it is combined with plastic film, used in the dark place, not afraid of acid

Q: Can plastic wrap be steamed?: No, the plastic wrap can't be steamed for it is a kind of plastic package product. It usually uses ethylene as master batch and is made by polymerization reaction. The plastic wrap is mainly used for food heating in microwave, refrigerator food preservation, and fresh food and cooked food packaging. It is also widely used in the field of food packaging in family life, supermarket stores, hotels, restaurants and industrial production. Plastic wrap can be classified into many types according to the material it uses and the added plasticizer, and it can be applied to different occasions. Plastic wrap is favored by people for its convenience, economy and beauty. However, plastic wrap generally contains added plasticizers in the production process, and thus its impact on human health has also been a concern.

Q: How do geomembranes perform in high temperature liquid containment applications?: Geomembranes perform well in high temperature liquid containment applications due to their excellent thermal stability and resistance to heat. They are designed to withstand elevated temperatures without losing their physical properties or compromising their performance. Additionally, geomembranes are typically made from materials such as polyethylene or PVC, which have high melting points and can withstand prolonged exposure to high temperatures. This makes them a reliable choice for industries requiring liquid containment at elevated temperatures, such as chemical processing, oil and gas, or thermal energy storage.

Q: What are the different types of geomembrane welding techniques?: There are several different types of geomembrane welding techniques, including hot wedge welding, extrusion welding, hot air welding, and solvent welding.

Q: What is the role of geomembranes in oil and gas storage facilities?: Geomembranes play a crucial role in oil and gas storage facilities by providing a reliable barrier between the stored hydrocarbons and the surrounding environment. These impermeable liners prevent contamination of the soil and groundwater, ensuring compliance with environmental regulations. Additionally, geomembranes help to minimize the risk of leaks or spills, protecting the integrity of the storage facility and reducing the potential for accidents or environmental damage.

Q: What is the role of soot carbon particles in geomembranes?: When carbon?blacks are evenly distributed, they can absorb ultraviolet light, protect products from aging too early and increase the life time of products.

Q: what's the Pneumatic diaphragm valve model: Pneumatic diaphragm valve types have many types, for example G6B41J-10 type normally closed pneumatic, G6B41W-6.4 type, G6B41J-6.4 type, G6B41FS-6.4 type design and manufacture according to the gas dynamic diaphragm valve, pneumatic diaphragm valve GB12239, the length of the structure is GB12221 etc., there are many types of model and I suggest that choose the suitable one when buying it.
