Detailed Product Description: | HDPE geomembrane in sewage treatment which have outstanding contributions? Acid water contains different ingredients, alkali, chemical substances, etc., with strong damage, the use of general waterproof material not have any effect, HDPE geomembrane has good barrier properties, chemical stability, anti-aging and other characteristics, is one of the best selection of sewage treatment plants. So these characteristics which give the convenience it brings sewage? 1.HDPE geomembrane has excellent chemical stability, widely used in sewage treatment, chemical reaction tanks, landfill. 80 kinds of acid and alkali chemical resistance, high temperature resistance, asphalt, oil and tar, acid, alkali, salt and other corrosive media. Impermeable geomembrane effect 2.HDPE ordinary waterproof materials can not match, the water vapor permeability coefficient K <= 1.0 * 10-13g.cm / c cm2.s.pa. Small particles 3.HDPE geomembrane surface, increasing the friction coefficient, but also increases the stability of the slope, so that the available volume of smooth HDPE film can carry maximized. 4.HDPE geomembrane has excellent anti-aging, anti-UV, anti-break capability, can be exposed to the use of the material life of 50-70 years, provide a good guarantee for environmental impervious material. 5.HDPE geomembrane has excellent puncture resistance, resistant to most plant roots. 6.HDPE geomembrane excellent flexibility and deformation capacity with good mechanical strength makes it ideal for expansion or contraction of the base surface quality Geomembrane, can effectively overcome the uneven settlement of the base surface, tensile strength 28MP, elongation at break the rate of 700%. 7.HDPE geomembrane has a high flexibility, a variety of specifications laid forms to meet the requirements of different projects seepage wholesale Geomembrane, using hot-melt welding, weld strength, construction convenient, fast. 8.HDPE geomembrane materials used are non-toxic and environmentally friendly materials, seepage is a common principle of physical changes, does not produce any harmful substances, is the best choice for environmental protection, farming, drinking water pool. Geomembrane additives which are composed ::? Geomembrane for polymers, from 96% to 97.5% polyvinyl resin, 2% to 3% black and 0.5% to 1% of the additives. Depending on the environmental conditions and mechanism of action, the degradation of type Geomembrane is divided into oxidative degradation, extraction degradation, UV and thermal degradation Geomembrane, oxidative degradation is at the bottom of the landfill impermeable membrane impermeable geomembrane most The main types of degradation. Oxidation process is essentially a process of radical chain reactions can be divided into three stages, each stage of a process on behalf of an antioxidant (stabilizer) consumed during this period Geomembrane mechanical properties do not change, the major antioxidant and oxygen , alkyl peroxy radicals and free radicals and other substances react chemically or physically migration, extraction, washing and evaporation loss, etc., usually by oxidation induction time (OIT) test was measured, the experiment there are two types, i.e. OIT OIT test standard and high-pressure test. Phase II for induction of oxidative degradation, mechanical properties during this period Geomembrane remains unchanged, while the molecules will find significant changes in the general use of Fourier transform infrared spectroscopy analyzer (FTIR) analysis. Phase III is the oxidative degradation of the early stage of this physical effect occurs mainly in the molecular cross-linking the main molecular weight increases, the degree of crystallinity increased, no significant changes in the nature of the project; late into chemistry, to the role of the main chain scission, molecular weight reduced engineering properties decreased (eg fracture stress and strain, tensile modulus, etc.), until the final instability, stage three ends. Generally believed that when the engineering properties of Geomembrane (such as stress cracking, stress crack and crack strain) down to a specific value (50% of the engineering properties of the original value or to a specified value) when the following is considered its loss stable. Melt flow index MI constant load tests and notch tensile test NCTL is effective analysis of two experiments that stage, the former for molecular testing Geomembrane, the latter mainly to measure stress cracking characteristics. Geomembrane quality, Xinyang Geomembrane, Edison new materials and new materials provided by Edison Company. Edison New Materials Co., Ltd. (www.fangshenmo.com) strong, credible, in Dezhou site construction materials industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Edison new materials into the brilliant and you work for a better future! |
