        济南通风管道的材料及尺寸的基本要求
        Basic requirements for materials and dimensions of ventilation ducts
        一、通风管道的材料
        I. materials for ventilation ducts
        1 金属薄板:
        1 sheet metal:
        普通薄钢板:有良好的加工性能和结构强度,但易于生锈;
        Plain sheet steel: good processability and structural strength, but easy to rust;
        镀锌薄钢板:表面镀锌,有防锈作用,一般用来制作无酸雾作用的潮湿环境中;
        Galvanized steel sheet: galvanized surface, has the antirust function, used in making no acid fog effects in damp environment;
        铝及铝合金板:加工性能好,耐腐蚀,摩擦时不易产生火花,常用于有防爆要求的通风系统中;

        Aluminum and aluminum alloy plate: good processability, corrosion resistance, friction is not easy to produce sparks, often used in explosion-proof ventilation system;

        济南酒店厨房排烟罩

        不锈钢板:具有耐锈耐酸能力,常用于制作寒湿、寒酸的排风管道及化工环境中需耐腐蚀的通风系统;
        Stainless steel plate: with rust resistant acid resistance, corrosion resistance and ventilation system should be used in the production of cold dampness, poor exhaust pipes and chemical environments;
        塑料复合钢板:在普通薄钢板表面上喷上一层0.2-0.4mm厚的塑料层,常用于防尘要求较高的空调系统和-10度—70度温度下耐腐蚀系统的风管;
        Plastic clad steel plate: a 0.2-0.4mm thick plastic layer is sprayed on the surface of the plain sheet steel, which is often used in air conditioning systems with high dust resistance and ducts with corrosion resistance at -10 degrees 70 degrees;
        2 非金属材料:
        2 non-metallic materials:
        硬聚氯乙烯塑料板:适用于有酸性腐蚀作用的通风系统,具有表面光滑、制作方便等优点,但不耐高温、不耐寒,只适用于0—60摄氏度的空气环境,在太阳辐射作用下易脆裂;
        PVC board: suitable for ventilation system acid corrosion, has the advantages of smooth surface, easy to produce, but not high temperature, not cold, only suitable for 0 - 60 degrees Celsius in air environment, under solar radiation fragile;
        玻璃钢:具有轻质、高强、不燃、耐腐蚀、耐高温、抗冷融等特性。
        Glass fiber reinforced plastic: lightweight, high strength, non flammable, corrosion resistance, high temperature resistance, cold resistance, melting and other characteristics.
        二、通风管道尺寸的基本要求
        Two. Basic requirements for dimensions of ventilation ducts
        通风、空气调节系统的风管,宜采用圆形或长、短边之比不大于4的矩形截面,其最大长、短边之比不应超过10。风管的截面尺寸,宜按国家现行标准《通风与空气调节工程施工质量验收规范》(GB 50243)中的规定执行,金属风管管径应为外径或外边长;非金属风管管径应为内径或内边长。
        For ventilation and air conditioning systems, a rectangular section with a circular or long and short side ratio of not more than 4 shall be adopted, and the ratio of the maximum length to the short side shall not exceed 10. The section size of the wind pipe, should according to the current standard of "national ventilation and air conditioning engineering construction quality acceptance" (GB 50243) in the implementation of the provisions, the wind pipe diameter should be metal or the outer diameter side; non metallic duct diameter should be in diameter or length.
