通风管道按照材质的话可以分为几类？通风管道厂家为您介绍：通风管道应用范围越来越广，在各种行业中都起到了很大的作用。通风管道是空调系统中非常重要的一个部件，它根据用户需求的不同要使用不同的材质。下面就来给大家介绍一下常见通风管道的种类都有哪些。
How many types can ventilation ducts be classified according to their materials? Ventilation duct manufacturers introduce to you that the application range of ventilation ducts is becoming increasingly wide and has played a significant role in various industries. Ventilation ducts are a very important component in air conditioning systems, and different materials should be used according to user needs. Below, we will introduce to you the types of common ventilation ducts.
通风管道用于输送空气(送、回风系统)和排除有害气体(排风系统)。以下是通风管道的几个材质分析：
Ventilation ducts are used to transport air (supply and return air systems) and remove harmful gases (exhaust systems). The following are several material analyses of ventilation ducts:
普通冷轧钢板：价格便宜、易腐蚀 ，一般通风用送风、回风、新风、排风、排烟系统。
Ordinary cold-rolled steel plate: affordable and prone to corrosion, generally used for ventilation with supply air, return air, fresh air, exhaust air, and smoke exhaust systems.
镀锌钢板： 耐腐蚀性相比刚办好，但在加工过程中铁皮 对温湿度要求较高场合的送回风系统，超净系统中效过滤，易脱落，油漆不易附着器前和中效至过滤器之间的送风系统。
Galvanized steel plate: For situations where the corrosion resistance is relatively good, but the iron sheet has high requirements for temperature and humidity during processing, such as supply and return air systems, ultra clean systems with medium efficiency filtration, easy detachment, and difficult adhesion of paint between the front of the device and the supply air system between the medium efficiency and the filter.
铝合金板：不起尘、价格贵， 30级净化系统过滤器之后送风系统。
Aluminum alloy plate: dust-free and expensive, with a 30 level purification system filter followed by an air supply system.
硬聚氯乙烯板：表面光滑，不起尘耐腐蚀、价格较贵、易老化 ，过滤器后送风管，表面处理车间排风系统。
Hard polyvinyl chloride board: Smooth surface, dust-free, corrosion-resistant, expensive, and prone to aging. It is equipped with air supply pipes after the filter and exhaust systems in the surface treatment workshop.
通风管道在设计阶段，各工种（暖通、给水排水，供电照明与建筑专业）首先应协商好空间分隔，定出每种管道的标高范围。一般情况下不得越出给自己规定的界限。遇有个别管段要越界时应与其他工程协商。
During the design phase of ventilation ducts, each profession (HVAC, water supply and drainage, power supply and lighting, and architecture) should first negotiate space separation and determine the elevation range of each type of duct. Under normal circumstances, one should not exceed the limits set for oneself. When encountering a section that needs to cross the boundary, it should be negotiated with other projects.
