stucco aluminium duct cladding

Stucco aluminium duct cladding is a kind of commonly used thermal insulation aluminum material in the market, which is widely used in various fields such as lightness and convenience. Up to now, the thermal insulation aluminum sheet has gradually gained great popularity in various areas, such as our common thermal insulation pipeline.
On the basis of the stucco aluminium duct cladding, the unevenly shaped aluminium cladding is completely formed on the surface after calendering.

In the stucco aluminium duct cladding belt production process, quality problems are prone to occur due to equipment or personnel operating errors. Here, the aluminum industry summarizes common quality problems as follows. I hope the production department can pay attention to this problem.
 
Oil pollution is a common quality problem: oil pollution refers to the excessive oil on the surface of the aluminum tip after rolling. And the excess oil other than the rolling oil film is carried, which is visible to the naked eye during the process of slitting production and finished product inspection Oily surface. These oils are mainly caused by throwing, splashing, dripping on the surface of the box at the roll neck or above and below the exit of the rolling mill, abnormalities in the roll cleaner of the rolling mill, and dripping oil from the rolling mill thickness measuring head, and are often dirty and complex.


 
Solution: Strictly inspect the production equipment before production. If there is too much oil in the equipment, clean it in time and find the cause. At the same time, clean the surface of the production product. If the product that can not be cleaned is scrapped, the stucco aluminium duct cladding is prohibited from entering the warehouse and entering the market.
 
Scratches are frequent visitors of quality problems: scratches, scrapes, and bruises are intermittent or continuous single groove-like scars on the surface of stucco aluminium duct cladding. Generally, it is produced when sharp objects slide relative to the foil surface after contact.
 
The main reasons: the surface of rollers and guide rollers have sharp defects or hard debris; the mechanical guide rollers for shearing, winding, and slitting have sharp defects or dry debris on the guide path. Scratch: Bundles (or groups) of scars distributed on the surface of the box material due to relative sliding or misalignment between the edges and surfaces, or surface-to-surface contact.

Orange peel embossed aluminum plate/coil is mainly used in refrigerators, air conditioners, pipe insulation, liner insulation and other industries. The surface can be anodized, painted, mirror and other processing, so that it forms a beautiful appearance, widely used in packaging, home appliances, building, curtain wall decoration and other aspects.
