HDPE Geomembrane Liner Used in Salt Pond Project
HDPE Geomembrane Liner is widely used in the salt industry such as salt field crystallizers, salt tank covers, salt films, and salt tank plastic films.
Sea salt drying refers to the evaporation of water in seawater through a series of processes to get sea salt. The main method of extracting salt from seawater is the 'salt field method', which is an ancient and still used method. Use this method. It is necessary to choose large flat beaches in areas with a mild climate and enough sunlight to build salt pans.
Ancient sun-dried salt, also known as sun-dried salt, is a salt-making method that relies on sunlight and wind to evaporate and crystallize. In this process, the salt fields have different concentrations due to different evaporations, which form blocks of rich colors. There are four major processes in the solarization method: moisture absorption, brine production, crystallization, and salt collection. Omit salt making, when the seawater is high tide, the seawater is pumped into the evaporation pond through the water lifting equipment of the pumping station, and the seawater is concentrated into saturated brine through evaporation and filtration, and then the saturated brine is poured into the crystallization pond to continue the sun.
The salt produced by the ancient sun-dried salt is only raw salt. To turn it into imported table salt, the raw salt needs to be sent to the processing workshop for fine processing, after crushing, washing, drying, screening, color sorting, packaging, quality inspection, etc. More than a dozen processes can produce various specifications and uses of sun-dried sea salt series products according to the differentiated needs of consumers.
Geomembrane is used for anti-seepage and isolation of salt field crystallization ponds, brine ponds, anti-seepage, and sun-dried salt film-salt pond covering isolation speeds up water evaporation and speeds up brine crystallization to increase unit salt production.
The application advantages of HDPE anti-seepage membrane in the salt drying project of the salt pond:
1. The finished product of the HDPE impermeable geomembrane is black high-strength coiled material, which has high wear resistance and light and heat absorption performance. It can absorb and convert natural sunlight into heat energy. Speed up the evaporation of water, increase the speed of salt crystallization and separation, and increase the salt production per unit area.
2. HDPE impermeable membrane will not produce harmful substances at high temperatures like PVC material, ensuring the infinite safety performance of the finished salt.
3. After using HDPE anti-seepage membrane as the anti-seepage isolation of the salt pond, it is beneficial to maintain the cleanliness of the salt and reduce the impurity components, and the unit price is high.
4. After using HDPE anti-seepage membrane as the anti-seepage isolation of the salt pond, it is beneficial to the collection of crystalline salt to increase the output.
5. HDPE impermeable geomembrane has high strength and abrasion resistance, and a high return on investment.
