| 特点 The characteristics of 由于铁皮容易在各种环境下发生化学反应，造成腐蚀、生锈。而锌在干燥的空气中几乎不发生变化。在潮湿的空气中，锌表面会生成致密的碱式碳酸锌膜。螺旋风管主要是在风管铁皮上镀上一层锌，对铁皮起到保护的作用。锌镀层经钝化处理、染色或涂覆护光剂后，能显著提高其防护性和装饰性。 It is easy to produce chemical reactions in various environments, causing corrosion and rust. Zinc in dry air hardly changes. In humid air, the zinc surface produces a dense alkaline zinc carbonate film. The spiral duct is mainly coated with zinc on the duct, which protects the tin. The protective and decorative properties of zinc coating can be improved by passivation, dyeing or coating. 螺旋风管具有以下特点： The spiral duct has the following characteristics: 1、外观光滑，无锌瘤、毛刺，呈银白色； 1. Smooth appearance, no zinc tumor, burr, silver white; 2、安装方便，连接点少； 2. Convenient installation and little connection; 3、通风阻力小，通风噪声小； 3. Small ventilation resistance and low ventilation noise; 4、强度与刚性均好； 4. Good strength and rigidity; 5、厚度均为可控，在5-107μm之内任意选择； 5. The thickness is controllable and can be selected arbitrarily in 5-107 mu m. 6、无氢脆、无温度危害，可保证材料力学性能不变； 6. No hydrogen embrittlement and no temperature hazard, the mechanical properties of materials can be guaranteed. 7、可代替部分需热镀锌的工艺； 7. Can replace part of the process of hot galvanizing; 8、耐腐蚀性好，中性盐雾试验达240小时； 8. Good corrosion resistance, neutral salt spray test for 240 hours; 9、采用热镀锌方法完成，适用于各种强酸、碱雾气等强腐蚀环境中； 9. The hot-dip galvanizing method is applied to the strong corrosive environment, such as strong acid and alkali fog. |
