1.0mm thick (acid and alkali resistant) anti-seepage lining material for sewage treatment tank

Description :

　　Composite waterproof board; A waterproof material formed by thermal composite of polyester polyester short filament (long filament) geotextile and waterproof board. The width is 1-6m, and the material of the waterproof board is available; LDPE, HDPE, EVA, ECB. The commonly used materials for tunnel, subway, culvert, and civil air defense engineering are EVA, ECB, and waterproof board width; 1-3 meters, main specifications include:; 1.0mm/200g，1.2mm/300g，1.5mm/300g，1.5mm/350g，200g/1.0mm/200g，250g/1.5mm/250g。 We can produce according to customer requirements. Composite forms include; Sling style, strip style, fully composite, two fabric composite, one fabric composite. Its main role in engineering; Waterproof and anti-seepage. The product has high physical and mechanical performance indicators such as tensile strength, tear resistance, and burst resistance. It has the characteristics of high strength, good elongation, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, and good anti-seepage performance. It can meet the needs of civil engineering such as anti-seepage, isolation, reinforcement, crack prevention and strengthening in water conservancy, municipal engineering, construction, transportation, subway, tunnel, and engineering construction. Due to the use of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments.

　　Tunnel waterproof boards are generally divided into separate waterproof boards and composite waterproof boards, with materials includingEVAandECBThere are two types of separate tunnel waterproof boards. Generally, the board and geotextile are used separately, while the composite waterproof board is generally made by combining geotextile and board heat, and can also be compounded with asphalt adhesive (self-adhesive composite waterproof board) on one side of the board. The geotextile commonly used on the waterproof board is generallythree hundredKe orthree hundred and fiftyKe's geotextile.

　　Tunnel waterproof board has excellent flexibility, impermeability, elongation and wear resistance; Has good isolation and puncture resistance; No chemical pollution; Resistant to acid, alkali, and various chemical substances, with good dimensional stability, good adhesion, and easy construction.

　　Geomembrane, also known as waterproof board or anti-seepage membrane. Traditionally, geomembranes with a thickness of ≥ 0.8mm are called waterproof boards, with a range of specifications and models; Thickness 0.2-2.5 millimeters, width; 1-6 meters, divided into composite and homogeneous (light plate) types, with materials available; LDPE, HDPE, EVA, ECB. Colors available; Black, milky white, semi transparent white, transparent white. The main functions of geomembranes are in subways, basements, and tunnels Air raid shelter. The anti-seepage lining of culverts, anti-seepage of highway and railway foundations, and the use of geotextiles, bentonite waterproof blankets and other geotechnical materials in sanitary waste landfills to prevent liquid leakage and gas volatilization. Its main function in rock engineering is anti-seepage and isolation, but it also plays a role in strengthening and protecting. It is mainly used for anti-seepage in engineering projects such as earth rock dams, rock fill dams, masonry dams, concrete dams, tailings dams, sewage storage dams, channels, storage tanks, septic tanks in breeding farms, lotus root ponds, aquaculture, solid waste tanks, etc

　　impermeable membraneThe standard name is polyethylene geomembrane, mainly made of a milky white semi transparent to opaque thermoplastic resin material - polyethylene resin. Polyethylene is a high molecular weight polymer, which is a non-toxic, odorless, and tasteless white particle with a melting point of about 110 ℃ -130 ℃ and a relative density of 0.918-0.965; The anti-seepage membrane has good heat and cold resistance. Good chemical stability, high rigidity and toughness, good mechanical strength, excellent resistance to environmental stress cracking and tear strength. As the density increases, the mechanical and barrier properties will correspondingly improve, and the heat resistance and tensile strength will also be higher; Can resist corrosion from acids, alkalis, organic solvents, etc.

　　Waterproof board is a type of anti-seepage material made from polymer materials, which can prevent liquid leakage and gas evaporation. Widely used in construction, transportation, subways, tunnels, and engineering projects. EVA (ethylene vinyl acetate copolymer) generally refers to ethylene vinyl acetate copolymer; Ethylene vinyl acetate copolymer, abbreviated as EVA in English, code: 1314, molecular formula: (C2H4) x. (C4H6O2) y, chemical properties: universal polymer.

　　A. Characteristics

　　Strength - Under the same weight specifications, the tensile strength in all directions is higher than other needle punched non-woven fabrics.

　　Anti UV light exposure - has extremely high UV resistance.

　　Extreme high temperature resistance - able to withstand temperatures up to 230 ℃, maintaining structural integrity and original physical properties at high temperatures.

　　Permeability and plane drainage - The waterproof board is thick and needle punched, with good plane drainage and vertical permeability, and can still maintain this performance after many years.

　　Creep resistance - Creep resistance is superior to other geotextiles, therefore it has good long-term performance. It can withstand the erosion of common chemical substances in soil and the corrosion of gasoline, diesel, etc.

　　Ductility - It has a good elongation under certain stress, allowing it to adapt to uneven and irregular surfaces.
