Three conditions for inventory of photovoltaic modules
The design lifetime of photovoltaic modules is approximately 20 to 30 years. The thermal performance test in reliability is a design verification of photovoltaic modules used in the simulation of the ground, allowing the module to operate for more than 20 years under normal climate conditions. The specification requires that the module be heated. Cycling test, wet freezing test, and damp heat test to confirm that the component can withstand the negative temperature effect after high temperature and high humidity, as well as fatigue and thermal failure caused by repeated changes in temperature, and to determine that the PV module is exposed to high humidity. The thermal stress and ability to resist the long-term penetration of moisture. 1. The sensitivity of different materials of photovoltaic components to light is different. For durable materials such as most paints and plastics, the short wavelength band of ultraviolet light is responsible for the aging of most polymers. However, for materials that are not so durable, such as some pigments and dyes, the long wavelength and even visible light of UV light can also cause serious aging. 2. When the temperature of the aging chamber of photovoltaic modules rises, the damage of light will increase. Although temperature does not affect the main photoreactions, it does affect secondary chemical reactions. Laboratory burn-in tests must provide precise temperature control, and the process of aging is usually accelerated by increasing the temperature. 3. Dew, rain, and high humidity in the aging box of PV modules are the main causes of moisture damage. Studies have shown that items placed outdoors are on a daily basis for a long period of time (an average of 8-12 hours per day in wet conditions. Studies have found that dew formed by moisture is a major factor in outdoor dampness. Dew is more harmful than rain because it is attached. The longer the material, the more serious the absorption of moisture, of course, the rain is also a great hazard to the material, rain will cause thermal shocks.For example, a car in a hot summer day, the temperature of the car suddenly due to showers Rapid cooling will cause shocks, and mechanical erosion caused by rain erosion will also accelerate the aging of materials, such as the coating of wood removed by the rain to remove the surface aging layer, exposing the unaged inner layer to sunlight, and further Ageing. Polymer Concrete Cells For ER/EW Processing Of Nonferrous
Long-term impermeability, free of corrosion, 20+ years warranty
The structural core of electrolytic cells is bolstered with sturdy external seismic reinforcement blocks confining its floor supports, and includes a robust, internal bidirectional, pultruded FRP bar mesh reinforcement which positively maintains integrity should the cell fail due to catastrophic events. Electrolytic cell installation protocols call for lateral wall collaboration between cells,thus reducing stress levels of cell around 40% under normal operating conditions.

Electrolytic cells are designed, built and installed to satisfy the most stringent requirements requested by tankhouse operators worldwide. In most cases their main request is to guarantee full operating availability throughout the plant's lifespan, maximizing production of high-purity metal (copper, zinc, nickel, cobalt, lead or other nonferrous metals) with absolute safety for people and the environment. Additionally, cells must accommodate changes for continuous improvement of the electrolytic process, integrating efficiently with upgrades of complementary equipment such as anodes, cathodes, cap, boards, overhead crane electrolyte agitation systems, acid mist control devices, thermal insulation among many others.
The Internal layer is a monolithic tank made with multiple layers of fiber-reinforced vinyl ester resin (FRP) complying with chemical barrier international norms that assure long-term impermeability and corrosion resistance.
The Intermediate layer is the structural core made with polymer Concrete, with a patented formulation to achieve a low coefficient of thermal expansion, providing long-term structural integrity with low thermally-induced stresses
The External layer is a standard seal layer of FRP that further protects the structural core from electrolyte splashes and spills. Optionally,this external seal may be specified with multi-layered oriented fiber reinforcements to guarantee trouble-free operation in unusually extreme operating environments.
Benefits of electrolytic cells
Our monolithic internal tank manufactured with multiple layers of fiber-reinforced premium vinyl ester resin. It has continuous service without leakage, free of corrosion and structural flaws which operating under normal conditions as specified for each project.
Swift, accurate and less costly installation
Electrolytic cells include features that allow reduction of 25% or more in time needed for cell erection, alignment and leveling compared to time required with conventional polymer concrete cells. Dimension tolerances for electrolytic cells are consistently tight, simplifying installation in the most demanding applications,including plants with automated crane systems.
Minimum cleaning time and water consumption
The rounded internal shape,optional sloped cell floors,and smooth,flat finish of the internal tank,facilitate water sweeping and drainage of heavy sludge,with reduced water usage and accelerating return to service after each cleaning.
Minimum maintenance cost
The robust, virtually impervious internal tank that is chemically bound to the polymer concrete structural core during molding is tolerant to operating abuse its smooth,non-stick surfaces minimize adhesion of contaminants.
Maximum operational safety
