| 螺旋风管有哪些特点： What are the characteristics of the spiral pipe?: 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。 Because the iron sheet is easy to react in various environments, it causes corrosion and rust. Zinc hardly changes in dry air. In the humid air, basic zinc carbonate, zinc surface will generate dense membrane. The spiral air pipe is mainly coated with a layer of zinc on the iron sheet of the wind pipe, and plays a protective role to the iron sheet. The passivation and coating of zinc coating can improve its protection and decoration. 螺旋风管具有以下特点： The spiral air duct has the following characteristics: 1、外观光滑，无锌瘤、毛刺，呈银白色； 1, the appearance of smooth, no zinc tumor, burr, silver white; 2、安装方便，连接点少； 2 、 easy to install and less connection; 3、通风阻力小，通风噪声小； 3, ventilation resistance is small, ventilation noise is small; 4、强度与刚性均好； 4, both strength and rigidity are good; 5、厚度均为可控，在5-107μm之内任意选择； 5, the thickness is controllable, optional within 5-107 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, no temperature hazards, can ensure the mechanical properties of materials unchanged; 7、可代替部分需热镀锌的工艺； 7, instead of part of hot-dip galvanizing process; 8、耐腐蚀性好，中性盐雾试验达240小时； 8, good corrosion resistance, neutral salt spray test up to 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 method is adopted by hot-dip galvanizing, which is applicable to strong acid, alkali, fog and other corrosive environments; 10、可根据客户要求，专门设计、定做各种规格风管。 10, according to customer requirements, specially designed, customized pipes of various specifications. |
