The ventilation pipe is mainly used in industry and construction engineering, and its design field is very wide. The working environment for oil absorption, smoking and dust removal now requires the use of ventilation pipes. Using natural air instead of indoor air to improve indoor air quality. What is the material of ventilation duct? How to improve the indoor air quality?

　　使用通风管道:

　　Use ventilation ducts:

　　1. 净化空调系统风道:镀锌板、不锈钢;(严禁使用可能受尘源污染的FRP及复合材料)

　　1. Air duct of purification air conditioning system: galvanized sheet and stainless steel; (FRP and composite materials that may be polluted by dust sources are strictly prohibited)

　　2. 空调系统风道:镀锌板、彩钢保温板;(可使用玻璃纤维及复合材料)

　　2. Air duct of central air conditioning system: galvanized plate, color steel insulation plate; (fiberglass and composite materials can be used)

　　3.环境控制系统风道:镀锌板、不锈钢;(可使用塑料、玻璃纤维、复合材料等)

　　3. Air duct of environmental control system: galvanized sheet, stainless steel; (plastic, glass fiber, composite materials, etc. can be used)

　　4. 工业通风系统风道:钢板、镀锌板;(荔波通风管道。可使用塑料、玻璃纤维、复合材料等)

　　4. Air duct of industrial ventilation system: steel plate, galvanized plate; (Libo ventilation duct. Plastic, glass fiber and composite materials can be used)

　　注:玻璃纤维风管按防火设计规范要求可分为有机和无机两种禁用有机材料;

　　Note: fiberglass duct can be divided into organic and inorganic forbidden organic materials according to the requirements of fire protection design code;

　　5. 特殊场合风道:矿山用涂胶风道、矿山用塑料风道;(要求具备阻燃、防静电矿井安全特性)

　　5. Air duct for special occasions: rubber coated air duct for mine and plastic air duct for mine; (it is required to have the safety characteristics of flame retardant and anti-static mine)

　　通风管道如何改善室内空气质量:

　　How to improve indoor air quality by ventilation duct:

　　1. 为人们提供他们需要呼吸的氧气。

　　1. Provide people with the oxygen they need to breathe.

　　2. 稀释室内污染物或气味。

　　2. Dilute indoor pollutants or odor.

　　3.释放室内过程中产生的污染物。

　　3. Release pollutants generated in the indoor process.

　　4. 清除房间内多余的热量或湿气。

　　4. Remove excess heat or moisture from the room.

　　5. 提供室内燃烧设备燃烧所需的空气。

　　5. Provide air for combustion of indoor combustion equipment.

　　以上是通风管道材料及如何改善室内空气质量的详细介绍，通风管道的应用领域主要涉及:无尘车间净化系统的电子行业、医药和食品无菌车间净化系统、酒店、工厂、写字楼、购物医院空调系统、工业污染控制与灰尘、烟雾和排风管道,工业环境中,如石油抽吸或post送风管,煤矿排水气体与排水气体系统,煤矿的环境控制是送回风系统等等。

　　The above is a detailed introduction to the materials of ventilation duct and how to improve the indoor air quality. The application fields of ventilation duct mainly involve: the electronic industry of clean workshop purification system, the purification system of pharmaceutical and food sterile workshop, the central air conditioning system of hotels, factories, office buildings, shopping center hospitals, industrial pollution control and dust, smoke and exhaust ducts, and the industrial environment, such as petroleum Suction or post air supply pipe, coal mine drainage gas and drainage gas system, coal mine environmental control is air supply and return system, etc.
