　　通風(fēng)管道的材料有很多，需要特別注意使用的細(xì)節(jié)，才能確保后期的正常使用。下面為大家?guī)?lái)關(guān)于通風(fēng)管道常用材料的相關(guān)知識(shí)。

　　There are many materials for ventilation ducts, and special attention needs to be paid to the details of use to ensure normal use in the later stage. Below, we will bring you relevant knowledge about commonly used materials for ventilation ducts.

　　1、鋼板

　　1. Steel plate

　　鋼板有兩種，一種是普通鋼板，厚度約為0.5毫米至4毫米間，規(guī)格一般為0.9米、1.8米和12米，具有加工性能好、機(jī)械強(qiáng)度高的特點(diǎn)和低廉的價(jià)格。另一種是鍍鋅鋼板，厚度約為0.5毫米~1.5毫米，規(guī)格與普通薄鋼板一樣，鋼板表層涂有保護(hù)層，可防腐蝕，一般采用在防潮風(fēng)管系統(tǒng)中。

　　There are two types of steel plates, one is ordinary steel plate, with a thickness of about 0.5 millimeters to 4 millimeters, and the specifications are generally 0.9 meters, 1.8 meters, and 12 meters. It has the characteristics of good processing performance, high mechanical strength, and low price. Another type is galvanized steel plate, with a thickness of about 0.5 millimeters to 1.5 millimeters, and the specifications are the same as ordinary thin steel plates. The surface of the steel plate is coated with a protective layer, which can prevent corrosion. It is generally used in moisture-proof air duct systems.

　　2、不銹鋼板

　　2. Stainless steel plate

　　不銹鋼具有表面光潔、耐腐蝕、耐酸等特點(diǎn)，廣泛用于化工行業(yè)的風(fēng)管。但不銹鋼板在加工時(shí)容易彎曲，錘擊時(shí)會(huì)產(chǎn)生內(nèi)應(yīng)力和不均勻變形，導(dǎo)致板子變脆變硬。當(dāng)鋼被加熱到450~850并冷卻下來(lái)時(shí)，鋼容易變質(zhì)、變硬，出現(xiàn)裂紋。

　　Stainless steel has the characteristics of smooth surface, corrosion resistance, acid resistance, etc., and is widely used in air ducts in the chemical industry. However, stainless steel plates are prone to bending during processing, and internal stress and uneven deformation can occur during hammering, resulting in the plates becoming brittle and hard. When steel is heated to 450-850 and cooled down, it is prone to deterioration, hardening, and cracking.

　　3、鋁板

　　3. Aluminum plate

　　鋁板可分為純鋁、鋁合金，外形美觀、密度低、可塑性強(qiáng)、耐腐蝕等特點(diǎn)。另外，鋁板材質(zhì)是比較軟的，即便發(fā)生了碰撞，也不易產(chǎn)生火花。一般用于防爆通風(fēng)管道。

　　Aluminum plates can be divided into pure aluminum and aluminum alloys, which have the characteristics of beautiful appearance, low density, strong plasticity, and corrosion resistance. In addition, the aluminum plate material is relatively soft, and even in the event of a collision, it is not easy to generate sparks. Generally used for explosion-proof ventilation ducts.

　　4、塑料復(fù)合鋼板

　　4. Plastic composite steel plate

　　具有耐腐蝕、加工性能好等特點(diǎn)。其規(guī)格一般為0.45米、1.8米、0.52米、12米，溫度范圍為零下10攝氏度到70攝氏度。

　　It has the characteristics of corrosion resistance and good processing performance. Its specifications are generally 0.45 meters, 1.8 meters, 0.52 meters, and 12 meters, with a temperature range of minus 10 degrees Celsius to 70 degrees Celsius.
