How does toothpaste remove scratches?

In our social life, all kinds of things happen every day, and there is a certain scientific basis for the occurrence of each thing, many times we have a lot of unimaginable things that happen in real life, that is because we lack the relevant knowledge in that areaI don't understand the truth, so I think it's so magical, many people will ask, what is the principle of toothpaste to remove scratches? This is mainly because the tiny particles in the toothpaste have filled the gaps in the scratches.

In our social life, in fact, there are many small details of life, sometimes we are easily troubled by a small thing, all kinds of things may happen every day, but these things happen without warning, many times we often feel helpless about what happens, which has a lot to do with our usual life experience. For those small things that happen in life, we can use the little common sense in life to solve them.

The toothpaste we use when we brush our teeth every day has a great effect, and we all know that the toothpaste itself contains a lot of tiny particles, and these particles are that kind of baking soda.

Pretty much, this can eliminate some of the dirt in our mouths, and baking soda itself can play a role in removing dirt, and brushing your teeth every day can also keep your mouth clean.

Among them, those tiny particles in the toothpaste have a great repair effect on the scratches, we all know that many things will leave a scratch after being scratched, but once the scratch appears, it is difficult to eliminate, at this time people will choose to use toothpaste to fill these scratches, as long as the toothpaste is wiped off the scratches, those tiny particles in the toothpaste will fill the gaps in the scratches, at this time we can have a smooth feeling with the naked eye, so that the repair can not be completely repaired, This has a lot to do with the individual's vision.

The principle of toothpaste for repairing glass scratches.

The principle of toothpaste to remove scratches is to polish the scratches around them flat, so that the scratches cannot be seen.

This is because the toothpaste contains tiny particles that act as fillers and can remove scratches.

Actually, it's not to remove the scratches, it's just to fill in the scratches, toothpaste.

The grinding particles inside are filled into the cracks of the scratch, so it looks like a scratch on the surface.

I removed the same.

Toothpaste is delicate enough to fill in the small marks that cover the scratches, so it looks like removing the scratches to us.

OK. The abrasive ingredients in the toothpaste can be filled, and the moisturizer in the toothpaste can make the toothpaste glossy and blend in with the color of the car paint. So no matter what color of paint, it's okay to use toothpaste to deal with the tiny scratches that only destroy the varnish layer.

The main reason is that toothpaste also contains abrasives, which have the same abrasive effect as the professional scratch wax and touch-up paint pens we bought, but the abrasives in toothpaste are not professional paint abrasives, so its touch-up effect is limited.

A little deeper in the scratches.

For example, if the varnish layer is scraped off, revealing the white primer inside, even if the scratches are relatively short, the effect is not very good if you treat it with toothpaste.

Because the scratches are deeper, more abrasives in the toothpaste are needed to fill the scratches, but you will find that the scratches that have just been processed actually have an effect, although the white primer is not visible, and the scratches have returned to the color of the car paint, but the gloss of the scratches treated with toothpaste.

Much worse.

Toothpaste contains titanium oxide (rutile titanium dioxide) with a very fine particle size, and its hardness is greater than that of glass (, so it can be seen as a glass polish, which can be applied to scratches and smoothed out the fine scratches by repeated rubbing, thereby removing superficial scratches on the glass surface, but it is powerless for slightly heavier scratches.

Removal principle and other functions:

First, the grinding particles in the toothpaste, silicon, are filled into the cracks of the scratches on the surface of the screen such as glass quartz, and the raw materials used to produce these screens also have silicon components, so it looks like the surface scratches have been smoothed.

2. There is titanium oxide (rutile titanium dioxide) with very fine particles in the toothpaste, and its hardness is 6.0 to 6.5 than that of glass, so it can be regarded as a glass polish, which can remove superficial scratches on the surface of glass.

3. Because toothpaste contains abrasive materials, such as between the valve and the valve seat of the car, the "three precision parts" of the diesel car need to be grinded, and the toothpaste is an excellent abrasive material. If there are slight scratches on the car instrument mirror, wipe it with toothpaste, and the effect is excellent.

Fourth, toothpaste can also remove porcelain dirt, enamel aging scale, with a brush dipped in a little toothpaste wipe can be removed. Tea stains and coffee stains left in the enamel teacup can be repeatedly scrubbed after applying toothpaste to the inner wall of the cup, and it will be as shiny as ever after a while.

Definitely not, scratches are already physical damage, that is, there is already a very small pit on the screen, how can it be good with toothpaste.

Removing scratches with toothpaste – does it really work.

Wouldn't you stick a little toothpaste on a cotton pad and try to wipe it on a small area?

The size of the silica-containing particles in the toothpaste is generally about 10 m, generally not more than 20 m, and the particle size of some friction agents such as light calcium carbonate is generally 1 m-3 m, and the minimum size that can be seen by the human eye is about 50 m, that is to say, the scratches are much larger than the particles of the toothpaste friction agent, and it is difficult to make these particles firmly fill in the scratches by friction alone, and the scratches cannot be filled.

In terms of the physical characteristics of the commonly used fillers in toothpaste, the hardness of solid calcium carbonate and silica is about 7, which is equivalent to the hardness of glass screens. However, calcium carbonate and silica that act as toothpaste friction agents are both treated light calcium carbonate and low-hardness composite silica, and the reason why this is so is because the Mohs hardness of human tooth enamel is about 5-6, so the toothpaste industry standard stipulates that the Mohs hardness of the substance that acts as a toothpaste friction agent should be less than 5. It is generally believed that the Mohs hardness of toothpaste friction is more suitable at about 4, so toothpaste cannot polish glass screens with higher Mohs hardness.

And when sanding, if there are fine sand particles (Mohs hardness = 7) and other impurities on the environment or grinding tools (such as glasses cloth), it is easy to polish the screen more.

Because the toothpaste contains an abrasive, this ingredient gives the toothpaste a wax-like effect, which can reduce scratch marks. In addition to this, toothpaste can also simply act as an insulating effect to prevent rust in the short term, especially in white-painted cars.

I believe that many car owners have heard of "using toothpaste to remove scratches on the body paint", but what the real effect is, it is estimated that few car owners are clear, unless there are car owners who have tested it themselves. So today we're going to take a look, can toothpaste really remove car scratches? Does toothpaste go to car scratches?

In order to verify that the toothpaste is really as stated on the Internet, it can eliminate scratches on the car paint. I also did the test myself, and the test results tell us: toothpaste does have the effect of eliminating slight scratches on the paint surface of the car, but you can't expect the toothpaste to completely eliminate the scratches, after all, the cost of toothpaste is there, if the toothpaste can completely repair the car scratches, then the car beauty shop will not have no business to do?

Does toothpaste go to car scratches? It can be said that toothpaste to scratch is the lowest cost among several ways to go to car scratches on the Internet, it should be said that the cost is almost zero, everyone has toothpaste, but with toothpaste to scratch the car, the only *** should be dark car paint is not very suitable, it may make the painted area white, which has the opposite effect, so dark car paint cars are still used with caution.

It is also worth mentioning that toothpaste is not specifically designed to repair car scratches, so it will not be permanently attached to car scratches, as long as it rains heavily, the toothpaste will basically be washed clean. (Photo by Deng Xuequn) @2019

<>1. There is titanium oxide with very fine granularity (rutile titanium dioxide powder) in toothpaste, which is harder than glass, so it can be regarded as a glass polishing agent, and can be leveled by repeated rubbing of the grinding base to know the subtle scratches.

2. Toothpaste can be used to remove "slight" scratches, because toothpaste usually contains abrasive ingredients to remove "tooth stains".

3. First of all, clean the scratch parts that need to be treated with salt and water.

4. Take a clean towel and soak it slightly, and apply toothpaste to the towel or scratch area. Repeated gentle rubbing, scratches can basically be wiped clean or weakened.
