With the implementation of regulations, restaurants now require the installation of oil fume purifiers. However, the ventilation pipes of oil fume purifiers have been used for a long time, and it is inevitable that they will be damaged. Depending on the degree of damage, the repair methods adopted are also different. So what are the methods for repairing damage to ventilation ducts?

如果是通風管道外表面很輕微的破損,可以用專用的密封膠帶來進行修補即可

If the external surface of the ventilation duct is slightly damaged, special sealing tape can be used to repair it

如果是通風管道內表面有輕微破損,則可用專用修補膠進行修補

If there is slight damage to the inner surface of the ventilation duct, special repair adhesive can be used for repair

如果通風管道外表面的鋁箔層發生破損,而玻纖保溫層未發生損壞,則可選用一片合格的鋁箔片進行管道鋁箔表面的修補

If the aluminum foil layer on the outer surface of the ventilation duct is damaged, but the glass fiber insulation layer is not damaged, a qualified aluminum foil can be selected for repairing the surface of the duct aluminum foil

如果通風管道壁的破損已達到玻纖保溫層時,則可將破損的地方切割下來,開出雌雄搭接口,另選一塊完好的板材,根據切割下來的玻板尺寸切割好,留下雌雄搭接口,在四周接口上涂上修補膠及粘膠劑,根據工藝規范進行密封

If the damage to the ventilation duct wall has reached the glass fiber insulation layer, the damaged area can be cut off, a male and female joint can be made, and another intact board can be selected. Cut according to the size of the cut glass board, leave the male and female joint, apply repair glue and adhesive to the surrounding joints, and seal according to the process specifications

如果通風管道的破損比較嚴重,且破損面積比較大,有可能會影響通風管道系統的正常運行時,就需要對管道進行更換修補,以保證系統的正常運行

If the damage to the ventilation duct is severe and the damage area is large, which may affect the normal operation of the ventilation duct system, it is necessary to replace and repair the duct to ensure the normal operation of the system
