      Features

Geomembrane is a kind of waterproof material with basic raw material of high molecular polymer. It is mainly divided into LDPE geomembrane, HDPE geomembrane,  and all kinds of composite geomembrane.

  • Complete variety of specifications of width and thickness. Thickness: 0.2-2.0mm.

  • Excellent environmental stress resistant cracking performance.

  • Excellent performance of chemical erosion resistance.

  • Big scope of application temperature and long service life .

  • Low Permeability :HDPE lining systems are secure because leachate does not penetrate them Methane gas will not escape from the HDPE cover system .and rainwater will not infiltrate. 

  •  Chemical Resistance:HDPE ,resistant to a wide range of chemicals ,is not threatened by typical solid or hazardous waste leachates.It is also suitable for sludge and secondary containment  around chemical storage facilities 

  •  Ultraviolet Resistance:HDPE's resistance to UV exposure is further enhanced by the addition of carbon black .Additionally ,with the absence of plasticizers ,volatilization is not a problem

Q:What is the construction technology of geotechnical engineering?
The open cut method refers to a construction method that first the rocks (soil) of the part of the tunnel are all removed, the barrel and tunnel portal is built and then the tunnel is backfilled. The advantage of this method is that it is simple, rapid, economic and safe. It is chosen as the first excavation technology in the early stage of urban underground tunnel project.The disadvantage is that it may have larger impact on the surrounding environment.
Q:Can 1.5mm geomembrane be produced by blow molding?
Geomembrane produced by large blow molding machine is of thickness of 0.15-2.5mm and breadth of 1-9m. The geomembrane produced by small blow molding machine is of thickness of 0.05-1.0mm.
Q:What are the main usages and applications of high density polyethylene film (HDPE) in refuse landfill?
At the same time it can be used for the middle cover, fly eradication and deodorization. HDPE geomembrane is the core of urban household refuse landfill anti-seepage materials.
Q:what is the role that Imported HDPE geomembrane plays in impermeable reservoir bottom system in the landfill.
Basically no use.
Q:what are the diamond film?
"Diamond film" The name is really outdated because the market is disturbed. when this concept emerged, it has water prevent functions. Later on, the lens prices are getting lower and lower and the quality is getting bad.
Q:Which one should be used for p lanting lotus, woven geomembraneor or blow molding geomembrane?
Its anti-seepage effect is not as good as composite geomembrane and the cost of it is much higher than the composite geo-membrane. There are woven geotextile and composite woven geomembrane. Woven geotextile is not seepage-proof. Currently the seepage-proof geomembrane for planting lotus is generally blow molding geomembrane or composite geo-membrane.Composite woven geomembrane is seepage-proof. There isn't a product named wowen geomembrane.
Q:How to stick membrane on the cabinet?
1) Clean the surface of the cabinet. The 75%vol medicinal alcohol is recommended because it is easy to clean and dries rapidly. 2) Measure the size of the area where you want to stick membrane. 3) Tailor the membrane you bought according to the size. To avoid waste, a draft is recommended. 4) Stick the membrane from up to down gradually and check at all times to prevent the membrane from being slantways stuck. It is really a great trouble to deal with the membrane slantways stuck.
Q:the seepage-proof pavement of composite geomembrane.
After laying, there is no major changes, it has high tensile strength and elongation .9m, paving, two cloth one film. after waving and combination.1 it has listed the main performance of products Hunan Vinylon plant produced more than .5 indicators. ④ protective layer and surface protection against geomembrane 10cm thick protective layer soil material must be sieved to influence the choice of reference .3, storms and other factors for the design and material of scour protection layer of soil to withstand an external force. Domestic and international application of impermeable plastic film. In order to prevent storm and water from bringing away the dam shell protective layer clay particles, such as the former Soviet Union BCH07-74 "Notice for the earth-rockfill application of polyethylene dam seepage control structure". Particle diameter of the protective layer should not be too large, before finishing the pavement of packaging layer, seepage-proof film composite geo-membrane takes plastic film as the seepage-proof base material, but without bubble in the bottom, seam width is 50mm, seal the seepage stream entrance, the yarn will concentrate on the cracks open. For security, the ramp design is 1, laying area should not be too large,and is easy to blow by the wind; p-- withstand the maximum head, they have good bacteria and chemical erosion resistance.
Q:What are the requirements of geomembrane waterproofing construction for the base?
Geomembrane construction important surface poor base quality base quality directly affects the waterproof efficiency of plastic geomembrane plastic geomembrane as initial support (shotcrete, continuous wall) laying requires that the base surface should be very flat effortless and meet the ideal requirements according to engineering practice experience mention: Laying plastic geomembrane base should be flat without sharp objects base flatness should meet the D / L=1/6 ~ 1/10 requirements formula: D-- initial supporting base adjacent two convexes recess depth L-- distance between initial supporting base adjacent two convexes click ID to consult more questions
Q:What is the classification of film resistance?
1. The carbon film resistor is made by depositing crystallize carbon on a ceramic rod framework. Carbon film resistors have low cost. Stable performance. Wide resistance range. It has low temperature coefficient and voltage coefficient, is the most widely used resistor at present. 2. The metal film resistors. Coating the alloy material on the surface of the ceramic rods framework by vacuum evaporation . Metal film resistors have higher precision, good stability, and low noise and temperature coefficient than carbon film resistors, thus is widely applied in the instrumentation and communications equipment. 3. Metal oxidation film resistors is made by deposited a metallic oxide layer on the insulating rod. Because it itself is an oxide, it is stable at high temperature and thermal shock resistance with strong load capacity. 4. The synthetic membrane resistor is made by coating the conductive composite suspension liquid on the substrate, therefore, it is also called paint film resistor. Due to its grainy structure of the conductive layer, it produces a lot of noises, and has low precision. It is mainly used in the manufacturing of high pressure resistance and small resistors.
