目前国内新建现代化猪场,越来越多的猪舍采用轻钢结构形式。轻钢结构可以实现“工厂化制作、装配化施工”,更易于保障工期和施工质量,比较适用于猪场这类建设地点偏僻,总体建筑面积不大的项目。 At present, more and more pig houses adopt light steel structure. Light steel structure can realize "factory production and assembly construction", which is easier to guarantee the construction period and construction quality, and is more suitable for pig farms with remote construction sites and small overall construction area. 围护结构板材常用的为镀锌彩涂板、镀铝锌彩涂板、铝锰镁合金板、不锈钢板、钛锌板等。目前不锈钢板、铝锰镁合金板仅个别猪场项目有采用,猪舍采用较多的为镀锌彩涂板和镀铝锌彩涂板。 The envelope plate is commonly used for galvanized color coated board, aluminized zinc color coated board, aluminum manganese magnesium alloy plate, stainless steel plate, titanium zinc plate, etc. At present, stainless steel plate, aluminum manganese magnesium alloy plate are only used in some pig farm projects, and more galvanized color coated board and aluminum zinc color coated board are used. 彩涂板都是由基板、镀层、涂层组成。影响防腐性能的主要是涂层和镀层。按照镀层材质的不同分为镀锌彩涂板和镀铝锌彩涂板。金属铝在防腐上有其独到之处该金属在空气中会迅速形成致密而厚实的氧化铝膜,这种氧化铝膜的迅速形成阻止了腐蚀的进一步侵入。镀铝锌板利用了铝的氧化膜遮盖保护作用与锌对铁的电化学保护作用,一般认为较镀锌板有更好的防腐性能,但是镀铝锌对于氨水的耐腐蚀性能较镀锌材料差很多,所以在畜禽舍环境不建议采用镀铝锌。 Color coating board is made up of substrate, coating and coating. The coating and coating mainly affect the anti-corrosion properties. According to the different coating material is divided into galvanized color plate and aluminized zinc color plate. The metal will quickly form a dense and thick alumina film in the air, and the rapid formation of the alumina film prevents the further invasion of corrosion. Aluminized zinc plate covers the protective effect of aluminum oxide film and the electrochemical protection of zinc on iron. It is generally believed that it has better anti-corrosion performance than galvanized plate, but the corrosion resistance of galvanized zinc for ammonia is much worse than that of galvanized material, so it is not recommended to use galvanized zinc in the livestock and poultry house environment. |
