Even a slight surface rub will cause many small scratches on the surface of the অ্যালুমিনিয়াম বৃত্ত শীট. So in order to avoid scratches on the surface of the aluminum wafer, a protective film will be put on the surface of the aluminum circle or separated by paper to protect it, so as to avoid scratches caused by friction between the aluminum circles each other. At the same time in transport to be solid, so as to avoid sliding problems due to transport, so that the surface of aluminum round circle scratches. এছাড়াও, workers need to wear gloves during manual handling, so that sweat can be avoided on the surface of the aluminum circle plate, because the surface of the aluminum circle/aluminium circle is likely to be corroded or oxidized over time. More important point: in the processing, especially in the shear bending should pay attention to, if the surface quality requirements are higher, it is better to stick a protective film.
