　　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?

　　使用通風管道:

　　Use ventilation ducts:

　　1. 凈化空調系統風道:鍍鋅板、不銹鋼;(嚴禁使用可能受塵源污染的FRP及復合材料)

　　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. 空調系統風道:鍍鋅板、彩鋼保溫板;(可使用玻璃纖維及復合材料)

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

　　3.環境控制系統風道:鍍鋅板、不銹鋼;(可使用塑料、玻璃纖維、復合材料等)

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

　　4. 工業通風系統風道:鋼板、鍍鋅板;(荔波通風管道。可使用塑料、玻璃纖維、復合材料等)

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

　　注:玻璃纖維風管按防火設計規范要求可分為有機和無機兩種禁用有機材料;

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

　　5. 特殊場合風道:礦山用涂膠風道、礦山用塑料風道;(要求具備阻燃、防靜電礦井安全特性)

　　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)

　　通風管道如何改善室內空氣質量:

　　How to improve indoor air quality by ventilation duct:

　　1. 為人們提供他們需要呼吸的氧氣。

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

　　2. 稀釋室內污染物或氣味。

　　2. Dilute indoor pollutants or odor.

　　3.釋放室內過程中產生的污染物。

　　3. Release pollutants generated in the indoor process.

　　4. 清除房間內多余的熱量或濕氣。

　　4. Remove excess heat or moisture from the room.

　　5. 提供室內燃燒設備燃燒所需的空氣。

　　5. Provide air for combustion of indoor combustion equipment.

　　以上是通風管道材料及如何改善室內空氣質量的詳細介紹，通風管道的應用領域主要涉及:無塵車間凈化系統的電子行業、醫藥和食品無菌車間凈化系統、酒店、工廠、寫字樓、購物醫院空調系統、工業污染控制與灰塵、煙霧和排風管道,工業環境中,如石油抽吸或post送風管,煤礦排水氣體與排水氣體系統,煤礦的環境控制是送回風系統等等。

　　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.
