　　如何判斷風(fēng)管加工的好壞

　　How to judge the quality of air duct processing

1、工業(yè)通風(fēng)系統(tǒng)用風(fēng)管：鋼板、鍍鋅板；(可使用塑料、玻璃鋼、復(fù)合材料)；2、特殊使用場(chǎng)合用風(fēng)管：礦用涂膠布風(fēng)筒、礦用塑料通風(fēng)管；3、空調(diào)系統(tǒng)用風(fēng)管：鍍鋅板、彩鋼保溫板；(可使用玻璃鋼、復(fù)合材料)(注：玻璃鋼風(fēng)管可分有機(jī)、無(wú)機(jī)二種，根據(jù)設(shè)計(jì)規(guī)范有消防要求的禁用有機(jī)材質(zhì)；)4、環(huán)境控制系統(tǒng)用風(fēng)管：鍍鋅板、不銹鋼；(可使用塑料、玻璃鋼、復(fù)合材料)；5、凈化空調(diào)系統(tǒng)用風(fēng)管：鍍鋅板、不銹鋼；(使用中可能出現(xiàn)塵源污染的玻璃鋼、復(fù)合材料禁用)其次，我們要了解通風(fēng)管道的選材的要求：

　　1. Air ducts for industrial ventilation systems: steel plates, galvanized sheets; (Can use plastic, fiberglass, composite materials); 2. Air ducts for special occasions: mining coated fabric air ducts, mining plastic ventilation ducts; 3. Air ducts for central air conditioning systems: galvanized sheet, color steel insulation board; (Fiberglass and composite materials can be used) (Note: Fiberglass ducts can be divided into organic and inorganic types, and organic materials are prohibited according to fire protection requirements in design specifications;) 4. Air ducts for environmental control systems: galvanized sheet, stainless steel; (Can use plastic, fiberglass, composite materials); 5. Air ducts for purification air conditioning systems: galvanized sheet, stainless steel; (Glass fiber reinforced plastic and composite materials that may cause dust pollution during use are prohibited) Secondly, we need to understand the requirements for material selection of ventilation ducts:

　　各類(lèi)板材、管材等應(yīng)有質(zhì)量證明文件(包括出廠合格證、質(zhì)量合格證明及檢測(cè)報(bào)告等)和產(chǎn)品清單；安裝使用的材料：螺栓、螺母、墊圈、墊料、密封條、自攻螺釘、拉鉚釘、電焊條、各種帆布、無(wú)紡布、射釘、膨脹螺栓等應(yīng)符合產(chǎn)品質(zhì)量要求；，幾種常見(jiàn)材質(zhì)的對(duì)比：

　　All types of plates, pipes, etc. should have quality certification documents (including factory certificates, quality certificates, and testing reports) and product lists; The materials used for installation: bolts, nuts, washers, gaskets, sealing strips, self tapping screws, rivets, welding rods, various canvas, non-woven fabrics, injection nails, expansion bolts, etc. should meet the product quality requirements; Finally, a comparison of several common materials:

　　塑料板風(fēng)管。用硬聚氯乙烯塑料板制作而成，具有較好的化學(xué)穩(wěn)定性，常用來(lái)輸送有腐蝕性的氣體。按連接方法可分為咬口和焊接兩類(lèi)。風(fēng)管一般在加工廠或施工現(xiàn)場(chǎng)制作。一般工程量不大或施工現(xiàn)場(chǎng)場(chǎng)地允許時(shí)，可在現(xiàn)場(chǎng)加工制作風(fēng)管，采用手工操作和使用一些小型加工機(jī)械；Plastic sheet air duct. Made from rigid polyvinyl chloride plastic sheets, it has good chemical stability and is commonly used to transport corrosive gases. According to the connection method, it can be divided into two categories: bite and welding. Air ducts are generally manufactured in processing plants or construction sites. When the general engineering quantity is not large or the construction site allows, air ducts can be processed and manufactured on site, using manual operations and the use of some small processing machinery;
