Product Description:

Description of self adhesive hdpe geomembrane sheet: 


    HDPE is a non polar thermoplastic plastic with high crystallinity and perfect electrical properties,especially the high insulation dielectric strengh.This polymer is non-hygroscopic which can be used to packing with good waterproof steam.HDPE with Middle to high molecure weight have good impact resistance at normal temperature even in the zero 40 degree Celisius.

 

     Its surface won't wrinkle and is weather resistant.Because it is durable it has a long service life and acts as a flexible hinge that won't break.Our HDPE sheets can be customes produce to match specific colors,thickness,size and finish.

  • high insulation dielectric strength

  • perfect impact resistance

  • good heat /cold endurance

  • no toxic

FAQ
1Why use HDPE sheet?                                                                                                                                 

HDPE Sheet has an almost waxy feel to it and is pretty good at being a low friction wear strip material and is used probably more than any other plastic as a wear strip on conveyors or production lines of huge companies.

Q:What is the geomembrane material?
Function: anti-seepage, isolation Product use: geotechnical dam, rockfill dam, masonry dam and pressure concrete dam; dike, dam front level anti-seepage cover, vertical foundation impervious layer; tailings dam, Roads, highways, railway subgrade; roadbed and other ground salt control; expansive soils; roadbeds, reservoirs (pit, kangang); waste land; subway, basement and tunnel, tunnel seepage lining; And waterproof layer of collapsible loess; roof leakage.
Q:How to install the electric heating film?
1, Cleaning the ground and paving the extruded sheet of 2-3 cm thick. 2, Tailoring and laying the electrothermal film side by side according to the requirement. 3, Connecting the electric heating film parallelly (according to the standard construction connection drawings, single electrothermal membrane should not exceed 10 meters). 4, Using special tool to connect firmly the special clips with the electrothermal film metal loading bar and connecting the electric wire. 5, Wrapping connected parts with insulating plaster to prevent water and ensure insulation. 6, Allocating the air switch according to the total power, connecting the thermostat and sensor and putting the probe of the sensor probe into the area of the ground that is the easiest to be heated to prevent the heating film from being overheated. 7, adding the drive pipe to the sensor, cutting the drive pipe at the head of the sensor and sticking the sensor to the heated carbon strip of the electrothermal film with insulating plaster. 8, Checking it. 9, Wrapping the electrothermal film with waterproof cloth (for cement construction) or paving non-woven fabric (for floor or the floor sheet construction). 10, Starting the temperature controller to measure the temperature. 11, paving the geothermy plastic net, pouring cement mortar, inlaying floor tiles (cement construction) and paving the floor (floor construction) 12, The construction is completed.
Q:Which is better for ceramic film and organic film ?
Ceramic membrane is relatively better.
Q:What are the standards of PE seepage-proof geomembranes?
Geomembranes is a kind of waterproof barrier membrane with high-molecular polymers as basic materials which can be divided into: Polyethylene (PE) products: Two cloths film one film(protective geotextiles are sticked to both sides of seepage-proof membranes) one cloth and one membrane(seepage-proof membranes)
Q:What is the carbon resister
Carbon film resistor is a kind of film resistor. It adopts a high temperature vacuum coating technology to closely attached to the surface of the ceramic rod carbon film, and then add the appropriate joint cutting, and coated with epoxy resin to seal for protection. The surface is usually painted with green paint. The thickness of carbon film depends on resistance size, it is usually used the film thickness and the groove to control the resistor. The carbon resister is made by heating polymerization, which uses an organic adhesive to make a suspension liquid by the carbon ink, graphite and the filling material and then be coated on the insulating substrate. Gaseous hydrocarbons are decomposed in high temperature and vacuum, the carbon is deposited on a ceramic rod or a ceramic tube to form a layer of crystalline carbon film. changing carbon film thickness and carving groove to change the length of the carbon film, we can get different resistance. The carbon film resistance has low cost, poor electrical performance and stability, which is generally not suitable for general purpose resistors. But because it is easily made of high resistance film, it is mainly used for high resistance high voltage resistor. Its functions are same to the high voltage resistor. The error rate of carbon film resistors is generally divided into three grades: The error rate of level I is 5%, the error rate of level II is 10%, and the error rate of level III is 20%
Q:What are the technical parameters of seepage-proof geomembranes?
serial number item indicator common environmental protection 1 thickness mm 0.2 to 4 2 width m 2.5 to 8 3 tensile strength (vertically and horizontally) MPa≥17 ≥25 4 breaking elongation rate (vertically and horizontally) % ≥450 ≥550 5 angle tear strength N/mm ≥80 ≥110 6 carbon black content % 2.0 to 3.0 2.0 to 3.0 7 resistance to environment stress cracking F20   ≥1500 8 low-temperature impact in -70℃ approved 9 oxidative inductive time in 200℃   ≥20
Q:Is black HDPE geomembrane or dark green HDPE geomembrane better for landfill final cover?
as long as it is in line with the standard, any color is fine. according to the specific requirements, the color depends on the auxiliary materials.
Q:What is the seepage-proof geomembrane?
Co-extrusion technology is used during the production, the main material of it is high density polyethylene native resin with high quality. It has a low hydraulic permeability and excellent seepage-proof performance. The standard name of HDPE seepage-proof membrane is polyethylene geomembrane, which has a highly efficient molecular density.
Q:How to remove the heating film in the fish tank?
Heating rods can stick out the water surface. The temperature knob and wire part has been sealed, so there will be no leakage. If you see there is water vapor in the heating pipe, it does not matter, because that is the water vapor sealed in the tube. This vapor exists because it is difficult to achieve complete vacuum in domestic products. Instead, if you do not put all the heating rods into the water, the water will be unevenly heated. When the part out of the water is cold and the part inside of the water is hot, heating rods will crack, especially at the seal. By then, the water will flow into the rods causing water leakage.
Q:How is the oil film on the fish tank produced?
The environment of fish tank is the same with the sea. When it is contaminated or the self-renewal ability reduces (for example when the water is seldom changed), water will be eutrophication. Besides, sunshine is plenty and green algae overgrowths, which will consume a large amount of dissolved oxygen in water. This is the principle of green tide.
