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(fēng)管道外表面很輕微的破損,可以用專用的密封膠帶來(lái)進(jìn)行修補(bǔ)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(fēng)管道內(nèi)表面有輕微破損,則可用專用修補(bǔ)膠進(jìn)行修補(bǔ)

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(fēng)管道外表面的鋁箔層發(fā)生破損,而玻纖保溫層未發(fā)生損壞,則可選用一片合格的鋁箔片進(jìn)行管道鋁箔表面的修補(bǔ)

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(fēng)管道壁的破損已達(dá)到玻纖保溫層時(shí),則可將破損的地方切割下來(lái),開(kāi)出雌雄搭接口,另選一塊完好的板材,根據(jù)切割下來(lái)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(bǔ)膠及粘膠劑,根據(jù)工藝規(guī)范進(jìn)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(fēng)管道的破損比較嚴(yán)重,且破損面積比較大,有可能會(huì)影響通風(fēng)管道系統(tǒng)的正常運(yùn)行時(shí),就需要對(duì)管道進(jìn)行更換修補(bǔ),以保證系統(tǒng)的正常運(yùn)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
