锌可以起到保护的作用。 The galvanized spiral pipe is mainly a layer of zinc plated on the material of the pipe , and zinc can play a protective role. 就可以显著提高防护和装饰等效果。 After the galvanization is passivated, dyed or coated with a protective light agent , the effects of protection and decoration can be significantly improved. Now the galvanized spiral duct manufacturer introduces the advantages of spiral duct .
通风噪声也小; 1.Ventilation generates little resistance and ventilation noise is small ;
中性的盐雾试验240小时; 2.Good corrosion resistance , neutral salt spray test for 240 hours ;
3. Various ducts can be designed and customized according to customer site requirements.
4. The thickness is controlled within 0.5-1.5mm;
配件少; 5.Easy installation and few accessories ;
没有锌瘤和毛刺,银白色; 6, smooth appearance , no zinc tumors and burrs , silvery white ;
没有伤害的温度,可以保证材料力学性能; 7.No hydrogen embrittlement and no harmful temperature , which can ensure the mechanical properties of the material ;
适用于各种酸和碱的腐蚀环境中使用。 8. The method is completed by hot dip galvanizing , which is suitable for use in various acid and alkali corrosive environments.
9, good sealing can avoid the situation of air leakage.
