Single rough surface geomembrane, double rough surface geomembrane and column point geomembrane what is the difference?
Brown hdpe geomembrane, also known as rough geomembrane, is made of technical material from three layers of blowing film, which is made of about 97.5% high quality polyethylene, 2.5% carbon black, trace antioxidant and heat stabilizer.
The rough HDPE geomembrane includes single rough geomembrane and double rough geomembrane and single and double column point geomembrane, and in the project is mainly to increase the friction coefficient with the base and slope, increase the friction force, and play the role of anti-skid.
Homembrane is rough and smooth, and there are obvious differences between them:
1. Different looks
The appearance of rough geomembrane is rough, smooth geomembrane is smooth mirror surface, can reflect projective, looks more bright.
2. Different performance
The friction coefficient of rough geomembrane is larger than that, which is an important index of the surface friction coefficient, which is the shear strength and Angle of friction. In addition, rough surface geomembrane has better fracture elongation, environmental stress cracking resistance and environmental adaptability than smooth surface geomembrane.
3. Different applications
The rough geomembrane is mainly used in the slope prevention and sealing field of some daily domestic waste landfills and tailings ponds, while the smooth membrane is used in the seepage control body of landfill floor, artificial lake, reservoir and other projects.
4. Different prices
The processing cost of rough surface is higher than that of smooth surface geomembrane. Brown surface geomembrane processing technology is more special and complex, so the price will be more expensive.
Brown geomembrane and smooth geomembrane, each have various advantages, is not necessarily which better: rough geomembrane has coarse particles, can increase the friction coefficient and adhesion, very suitable for all kinds of dam reinforcement, and smooth geomembrane in this respect is no rough surface advantage, but the advantage of smooth geomembrane is lower cost, how to choose the main applications.
HDPE double column point rough surface geomembrane, the production process of the products in retain the original resin itself has strong mechanical properties and good elongation chemical performance stability on the basis of the increase of tensile resistance, wear resistance, puncture properties, acid and alkali resistance, microbial chemicals erosion function progress improved. The membrane surface column point is extended by a special model pressure roll. The column point is evenly distributed and beautifully distributed, and the friction coefficient is improved.
