摘要
陶瓷微粒水性反射隔热涂料是一种能显著减少太阳光辐射能量进入设施设备内部的新型涂料。通过在粮库储油罐顶、浅圆仓顶外表面及仓外辅助设施回风管和不锈钢电柜上涂刷反射隔热涂料,与对照组温度数据对比分析,表明陶瓷微粒水性反射隔热涂料使用后浅圆仓和油罐温降效果显著,浅圆仓和油罐仓顶最高温降分别为13.0℃和17.7℃,且隔热涂料能有效降低仓储设施回风管和不锈钢电柜的表面及柜内温度,温降高达25.1℃,可对控制柜内机电设备起到保护作用,降低安全风险并延长其使用寿命。另外,与常规菱镁板铝箔防水卷材相比,隔热涂料单独使用可在保证控温效果同时降低投资和维护成本。因此,陶瓷微粒水性反射隔热涂料在粮油仓储领域有较好应用前景。
Ceramic particle water-borne reflective insulation coating is a new type of coating that significantly reduces the amount of radiant solar energy entering the interior of facilities and equipment.In this paper,the comparison is made by applying reflective thermal insulation coatings to the roofs of storage tanks,the external surfaces of shallow silo roofs,and the return air ducts and stainless steel electric cabinets of the auxiliary facilities outside the shallow silo.In comparison with control group,the cooling effect of the shallow silo and oil tank after the use of ceramic particle water-borne reflective insulation coating is remarkable,the maximum temperature reduction in the roof of shallow silo and oil tank is 13.0℃and 17.7℃,respectively.Meanwhile,the thermal insulation coating effectively reduces the temperature on the surface and inside the return air ducts and stainless steel electric cabinets of the storage facility,with a temperature drop of up to 25.1℃.This protects the electromechanical equipment inside the control cabinets,reducing safety risks and extending its service life.In addition,compared to conventional magnesite board aluminum foil waterproofing membranes,thermal insulation coatings can be used alone to reduce investment and maintenance costs while ensuring temperature control effects.Therefore,ceramic particle water-based reflective thermal insulation coatings hold good application prospect in the field of grain and oil storage.
