Membrane switch has many advantages: It is resistant to water, dust, oil and harmful gas erosion, and is stable and reliable in properties. It has small volume, long service life, and convenient installation. Its panel can be washed without damage of characters on it. It also has rich color and elegant appearance. Your product will obtain more distinct features of the time by using the membrane switch. Main types of the membrane switch: With rigid or flexible printed circuit board as substrate, the membrane switch panel is made with plastic (polycarbonate, polyester, etc.) faceplate with colored decorative patterns printed on it. It is installed with keys with hand feeling or not. It is a kind of electronic component integrating switch function with decorative function, and also has a new human-machine interface. Its switching circuit and connection mode of the complete appliance can be finished by welding or plug-in. It is good.

The construction method: To lay it in the range of measurement. To lay the composite geotechnical membrane before the first required to lay a good sand cushion on the roadbed, laying the width of the design requirements set. When laying, do not allow the laying of folds, as far as possible to tighten. After the pavement, the U type nails or bamboo nails is used to fix. When laying composite geotechnical membrane, the surface of the sand layer is smooth, no hard protrusion, and timely fill sand cover, avoid direct exposure to the sun for a long time. When the composite earthwork film is laid, the length of the transverse lap and the longitudinal lap can meet the design requirements. After the composite geotechnical membrane is rolled out, the filling material is filled up in time, and after the soil is covered with light compaction mechanical compaction, only when the thickness of the overburden layer is larger than 0.6m, the soil can be compacted by heavy compaction machine. Composite geotechnical membrane according to the design requirements can be divided into two types of longitudinal force and lateral force, the laying of composite soil before the film to understand the design intent, strictly according to the design requirements of the laying.

Architectural glass film according to their functions can be divided into: Privacy film, decorative film, energy-saving insulation film, explosion-proof membrane, bullet-proof film, a film in which the explosion-proof and bullet-proof membrane can also be assigned to the category of the security film. According to the production process is divided into: Staining film, film clip, colors film, quantum film. Usually on the market of low-cost shoddy glass film membrane staining, mostly because it does not really have the energy-saving insulation anti-ultraviolet, and other functions, and life is short, mostly two to three years will fade off . Clip film is a film based on the original film on the additional plating up, and compare it with the film in terms of staining is usually longer life, but over time will slowly fade. According to architectural glass film classification: EEB film, security film and indoor decoration membrane. Function is different. Basic includes the following features: First, comfort and energy saving, always enjoy - energy-saving insulation, adjust the indoor temperature, saving money. Second, the protection of interiors and occupants of buildings - blocking more than 99% of harmful UV rays, protect the body health and prevent fading of furniture; outer shield sight, create a private space; shock-proof, reducing accidental injury; construct; invisible network security; the protection of private property Third, to improve the overall appearance of the building, to build a harmonious working environment IV reduction. annoying glare - to block sun glare, prevent light pollution, protect eyesight V. improve the efficiency of the company's employees - a variety of fancy, beautify the living room appearance, improve the indoor environment VI, explosion-proof, shock-proof, reduce injuries. build; invisible security net; protection of private property.

Geosynthetics is a general term of synthetic materials applied in the field of civil engineering. Classification of geosynthetics changes with the development of new material and new technique. Ministry of Water Resources of China enacted "Technical code for application of geosynthetics" with other relevant departments in 1998 and classified the geosynthetics into four categories, namely the geotextile, geomembrane, geocomposite, and special materials.

Doors and windows soundproof membrane effect is still very good, under normal circumstances, a qualified good installment doors and windows soundproofed reasonable film thickness is sufficient to achieve a compliant body sound insulation, windows and doors sound insulation membrane is to prevent noise intrusion, you can add a layer of tight sound insulation film or a relatively strong absorption of cotton close to the transport routes. In order to prevent TV, stereo, piano disturbing your neighbors, you can add ultra-thin glass absorption cotton in television, audio background wall, the effect is very good.
Yes, geomembranes can be used for landfill leachate collection systems. Geomembranes are impermeable liners that prevent the leachate from contaminating the surrounding soil and groundwater. They are commonly used as a barrier in landfill construction to contain and collect leachate, ensuring proper management and preventing environmental hazards.
