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?

如果是通风管道外表面很轻微的破损,可以用专用的密封胶带来进行修补即可

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

如果是通风管道内表面有轻微破损,则可用专用修补胶进行修补

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

如果通风管道外表面的铝箔层发生破损,而玻纤保温层未发生损坏,则可选用一片合格的铝箔片进行管道铝箔表面的修补

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

如果通风管道壁的破损已达到玻纤保温层时,则可将破损的地方切割下来,开出雌雄搭接口,另选一块完好的板材,根据切割下来的玻板尺寸切割好,留下雌雄搭接口,在四周接口上涂上修补胶及粘胶剂,根据工艺规范进行密封

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

如果通风管道的破损比较严重,且破损面积比较大,有可能会影响通风管道系统的正常运行时,就需要对管道进行更换修补,以保证系统的正常运行

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
