Metallographic sandpaper is a specialized sandpaper used for grinding during metallographic analysis, which is common in the laboratory but relatively rare elsewhere. Therefore, many people do not know that sandpaper can still play a variety of roles in daily life. Next, let's take a look at some unexpected uses of metallographic sandpaper?


Tight bottle cap: Girls have relatively little strength. When the bottle cap cannot be opened, they take sandpaper and cover it on the front of the bottle cap. Then, they can easily open the tightly sealed cap by twisting the cap.


Uneven nails: It is said that the hand is the second face, and it is important to keep the nails clean and tidy. If the nails are uneven, sandpaper can be used as a nail file. Using sandpaper to rub the nails is not very cool.

    The ball on the sweater: If I like the sweater, I won't be able to wear it anymore. It's a pity to throw it away. What should I do? Choose any type of metallographic sandpaper and gently wipe the sweater in the same direction to easily remove the hair balls, allowing you to go out beautifully.


Wrinkled skirt: Summer is coming, and a skirt that has been pressed for a whole winter is about to come on. When ironing a skirt, place a piece of fine-grained or medium grained sandpaper on the pleats to fix the fabric and help to iron out obvious creases.

    Fouling in the sink: Even the kitchen sink brush has no effect. Using metallographic sandpaper can easily remove yellow stains and scale, making it a great helper for the kitchen. However, don't use too much force to avoid leaving scratches.


Black scale at the bottom of the pot: After using the frying pan for a long time, thick black scale will be left at the bottom of the pot, which is very annoying. However, using sandpaper and cleaning agent can easily solve even the thick scale.


Rust: There is a layer of sleeve stains on the kitchen knife at home, which cannot be washed off. Simply use sandpaper to wipe it off, and once you wipe it off, it will look like new.

    The stubborn dirt in the ceramic tile gap: Take a fine-grained sandpaper, fold it in half, and rub the folded edge against the ceramic tile gap to remove the stubborn dirt on top. If using fine-grained sandpaper to wipe the gaps between ceramic tiles, try to avoid scratching the tiles and be careful not to leave scratches.

    Every day in the laboratory, I watch the metallographic sandpaper spinning and turning on the metallographic polishing machine, as if I have never been tired. Such a small piece of metallographic sandpaper can not only overcome difficulties in the laboratory, cover all the grinding requirements of materials, but also make such wonderful use of waste heat in the outside world. It's amazing!
