What to do if the transparent tape is difficult to tear off
We often use tape in our daily life, but if we use scissors or knives around us, how to tear the tape? Today I will teach you a few tips for tearing tape, let's take a look!
The first little coup, we need two coins, we put the coins on both sides of the tape one behind the other. After that, there is a little space in the middle of the coin, and we use the opposite force between the two coins, so that the tape can be easily torn off.
The second little coup, we use a toothpick to poke a small hole in it. Let's use some strength at the gap, so that the tape can be torn off, and it is very easy.
The third little trick is that we can tear the tape with bare hands. We put our index finger under the tape, put our thumb on it, and then force the tape to tear it off. The effect is also good.
How to remove the bottom glue left by scotch tape?
For different situations, there are different processing methods as follows:
1. For the traces of stickers on the surface of hard objects, we can use grease-free nail polish remover to coat the surface of the object, and then wipe it gently with a soft cloth; these can also be removed with industrial alcohol or gasoline trace.
2. If these stickers get on the skin, you can also use lemon juice to remove them.
3. For the more stubborn stickers on the carpet, the best way is to carefully trim off the traces of stickers on the top of the carpet pile.
Clear glue, a household staple, now has a new scientific use——out of shape“Smart Materials”.
Researchers use a laser to cut a strip of clear glue into thin half-centimeter strips“finger”, after immersion in water, 4“slender fingers”It curls up into a small robotic arm that can grab water droplets. Babak, professor of electrical, computer and biomedical engineering at Purdue University·Ziai pointed out that this invention can be used to collect water samples for environmental testing.
Clear glue is composed of cellulose acetate and adhesives, and has a unique structure suitable for the above-mentioned purposes.“Tape can be processed into different shapes, can interact with the environment, and perform specific functions. It is an inexpensive smart material.”
Adhesive tape can stick things because of the relationship of a layer of adhesive on its surface. The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives; in modern times, various polymers are widely used. Adhesives can stick to things because of the formation of bonds between their own molecules and the molecules of the objects to be connected, and this bond can firmly bind the molecules together.
Dip a sufficient amount of 95% alcohol with a soft cloth, and then gently wipe the sticker, the sticker will be easily softened and detached. At the same time, alcohol will not affect the surface of plastic parts or car paint What damage.
But sometimes it is found that alcohol is not very effective for some stickers. This is to use a soft cloth to dip a little gasoline and wipe the stickers. At this time, it should be noted that gasoline is harmful to certain plastics or paints.“to dissolve”Therefore, you must use it carefully: either wipe it on an unimportant place first, and use it if there is no problem; but be careful not to use too much gasoline, and the time should be as short as possible. Generally speaking, wiping the surface of the car body with gasoline for a short time has no obvious effect on the paint film on the surface of the car body. In this way, the stickers can be easily removed.
