Cement Equipment Higher Requirements
Jun 05, 2017

Cement Equipment With the increase of foreign construction and total contract (EPC) cement Project, China's cement equipment exports more and more. Because of the different countries and regions of the export, the equipment working conditions include the natural environment or the indoor and outdoor corrosion severity of the pollution, Cement Equipment and the quality of anti-corrosion coating is more and more high. With the increase of foreign construction and total contract (EPC) cement Project, China's cement equipment exports more and more. Cement Equipment Because of the different countries and regions of the export, the equipment working conditions include the natural environment or the indoor and outdoor corrosion severity of the pollution, and the quality of anti-corrosion coating is more and more high.

Cement equipment (steel structure) in the corrosive environment is very different, and in transport, storage, installation and production links will also be affected by environmental corrosion.


(1) The impact of the regional environment. Cement Equipment Different locations of the construction project corrosive environment is very large, for example, in the high-temperature humid rainy area, corrosion rate of 160 μ m, equipment corrosion is very harmful. Cement Equipment But in desert area, the year-round precipitation has little effect on corrosion. At the same time, a lot of cement equipment is exposed to the outside world to work, long-term by wind, sun, rain, coating weatherability and durability of the impact.


(2) The influence of dust fume. Cement Equipment The cement production line itself discharges the dust smoke to contain the SO2 and the nitrogen oxides (NOx) and so on harmful gas, Cement Equipment not only pollutes the air, also has the strong corrosion to the equipment, simultaneously the dust will wear the equipment surface.


(3) The impact of storage transport. With the continuous development of EPC project, the corrosion damage of equipment due to long-distance transportation is more and more. Most of the cement equipment through the ocean transport, the sea time February-March, and many for large naked pieces, salt mist of the marine atmosphere of the equipment for a long time corrosion, great harm.

Epoxy resin is the main film-forming material of the paint, a large variety, such as a single component, two-component and multi-component. In epoxy primer, Cement Equipment epoxy zinc-rich paint because it is rich in a large number of zinc powder cathodic protection, supporting the application of the best anti-corrosion performance, it and epoxy zinc phosphate paint compared to dry faster, anti-corrosion and anti-aging performance stronger. But from microscopic view, epoxy zinc-rich paint film surface is "flaky" there is "gap", need to be closed with closed paint, otherwise, the anti-corrosion effect is not necessarily better than epoxy zinc phosphate paint.


is the abbreviation of polyurethane resin paint. Cement Equipment Commonly used are aliphatic polyurethane, aromatic polyurethane and acrylic polyurethane, mostly used as topcoat. Aliphatic polyurethane is a aliphatic isocyanate components and advanced acrylic resin, pigments and solvents, composed of two components from dry paint, it has excellent weathering resistance, gloss, good color protection, but higher prices. and aromatic polyurethane (one-component) weather resistance is poor, not suitable for outdoor use. Acrylic Polyurethane (two-component) with hydroxyl acrylate and aliphatic isocyanate reaction, also has good weatherability and acid, alkali, salt (salt mist) corrosivity, Cement Equipment but the weatherability is slightly worse than aliphatic polyurethane. Polyurethane paint adhesion, film tenacity, impact resistance and wear resistance performance excellent, decorative good (surface fullness bright), acrylic polyurethane is the most commonly used cement equipment outdoor high-grade topcoat.
