How to choose the outdoor LED display? Keep in mind the three major points to buy zero risk

Outdoor LED display is a very common type of display screen, not only has a flexible installation size, but also greatly improved in terms of weight compared with traditional products, and the color is more clear and full, allowing everyone to see more For pleasing video footage. Then to buy the best quality outdoor LED display should pay attention to which points to buy it?
1, see the flatness of the screen
In order to ensure that the displayed image will not be distorted, the surface flatness of the outdoor LED display must be maintained within ±1mm. If this requirement is not achieved, and the phenomenon of unevenness locally, the outdoor LED display will play video. There is a problem with dead angles at the viewing angle. Therefore, it can be said that the flatness is a major factor in judging a quality outdoor LED display.
2, see the brightness of the screen
Under normal circumstances, the brightness of outdoor LED display should reach 1500cd/m2 above to ensure the normal display work, otherwise it will not allow everyone to see the playback of the image content due to insufficient brightness. Therefore, if you want to buy a good display of outdoor LED display depends on the quality of its LED lamp beads and brightness parameters.
3, see the white balance of the screen
When the ratio of the three primary colors of red, green, and blue is 1:4.6:0.16, the screen will show the purest white color. Therefore, if the display screen produced by outdoor LED display manufacturers has a slight deviation in the ratio of the three primary colors, it will lead to white. Balanced deviations can cause the display quality of outdoor LED displays to be affected, so it is also important to look at their white balance when purchasing.
The above three aspects are just a few points that you can refer to when purchasing an outdoor LED display. Everyone wants to have a good playback effect when buying an outdoor LED display, so it is necessary to choose from several aspects such as the flatness, brightness, and white balance of the display screen, so as to ensure that they can be purchased from outdoor LED display manufacturers.

Polymer Concrete Cells For ER/EW Processing Of Nonferrous

  1. Vinyl ester resin monolithic casting electrolytic cells
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.
2. Structure
Electrolytic cells are cast monolithically based on a patented, three-layer composite material system:
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

Long-term impermeability, free of corrosion, 20+ years warranty
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

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.
