My grandfather used to buy toothpaste skins in the countryside, and he can earn about 2000 yuan a month. He told me that the small toothpaste skins are very useful and the value after recycling is also very high. Our country has had the habit of brushing teeth for a long time. At first, it was not toothpaste that people use now, but tooth powder, which was used in bags, almost in the 1940 s and 1950 s. Later, foreign countries developed toothpaste, which immediately seized the market of tooth powder, that is, from that time on, many domestic enterprises began to produce toothpaste. I explained the origin of toothpaste to you earlier. It is precisely because toothpaste needs to be packaged before it is sold. At this time, for the sake of beauty and convenience, toothpaste skin was produced. At that time, toothpaste skin was not what we see now. In the 1970s and 1980s, toothpaste tubes were made of lead, aluminum, tin and other metals, and among all the waste recycling at that time, toothpaste tubes were the most precious, because the aluminum in toothpaste tubes at that time became a national Z-strategy material, so recycling became very important. At that time, the best toothpaste in our country was Zhonghua brand, followed by &”;invincible brand&”; and &”;Samsung brand&”;. Later, it was upgraded to &”;Guzhiling Toothpaste&”;. It is said that the output at that time could reach 21 million pieces. Different toothpastes naturally used different toothpaste skins. My grandfather told me that Chinese toothpaste skins were the most expensive at that time, and one could sell for 10 cents. If it was well preserved, it could sell for 15 cents, while the worst toothpaste skins needed five to six pieces to sell for 10 cents, because the materials used were different. At the beginning, all toothpaste tubes were not made of aluminum, but made of lead. It was not until the 1970s that they were replaced by aluminum tubes, and in the 1990s, they were all made of all-plastic composite materials, so now people can hardly see the toothpaste tubes made of aluminum. 1. It can be made into aluminum pot, aluminum pot and aluminum spoon. You may not have seen the kind of professional pot-mending or pot-making before. In the 1970s and 1980s, after collecting this aluminum, you can make a pot after reaching a certain amount. Now we have another pot like this in our house, but we just can&;t use it any more. This production method is very simple, that is, all the aluminum is gathered together, and after being heated into molten aluminum, we can make a pot we want according to the model. In previous years, this pot was basically used for cooking. Secondly, it can be made into a kettle, unlike the electric kettle that everyone uses now. In the past, it was boiled with coal and then put in a kettle. It was also more expensive to want a kettle of this kind in those days. Finally, there is a spoon for cooking, which is usually used at home or by chefs. The principle of making it is the same as before. 2. Mend some living furniture. When I was a child, I saw my grandfather use this recycled toothpaste tube to mend the washbasin. At that time, the washbasin was basically made of enamel, which was easy to break. Sometimes a small hole was broken, so I could use this toothpaste tube to mend it, so that I could continue to use it. We can also repair some other enamels, such as tea plates, bowls, etc., which are also repaired.You can mend them and continue to use them. As the saying goes, sewing has been mended for another three years, which is the principle. The previous things were of good quality and could be used for a very long time. 3. Friends who can make fishing gear know that there is a lead pendant at the bottom of a fishing rod, and this lead pendant is relatively important to guide the fishing line to sink, and this lead pendant was made of this toothpaste skin at that time, because he was in aluminum, and after burning him into aluminum water, he could make it according to the model of the lead pendant. 4. Making other aluminum products, such as some aviation materials that are not commonly used in our lives, such as airplane fuselage shells, were very important at that time. For us to study and manufacture these products, we needed a lot of aluminum to complete it. At that time, only by recycling toothpaste skins could we solve part of it, which was relatively cost-saving and solved the problem of consuming a lot of aluminum. It&;s not that no one has recycled it, but that few people use it now. Now all toothpaste is basically plastic, which is relatively low in cost. Secondly, it can save the consumption of these metals and protect the country&;s energy. Besides these, there are actually other advantages. For example, it is lighter in weight and convenient to carry, and this kind of plastic pipe is gradually formed. At this time, it means that people who recycle toothpaste skin have no business to do, so no one has recycled it until now. If someone continues to use it, it will definitely be recycled. After all, this profit is also very large. Based on a toothpaste skin at that time, an ordinary toothpaste skin was about 9-10 grams. A little bit better and heavier can reach 150-20g. At that time, about 2.7 million pieces can be produced nationwide. If a toothpaste is used for one month, the amount of toothpaste used in China should be about 700-800 million pieces at that time. That is to say, 630 tons can be recycled after one month. If calculated according to the price of one ton of aluminum, 2800-3500 yuan can be obtained, the total value will reach 1.76 million. If calculated according to the above 10 cents, 700-800 million pieces a month will be 7 million. Is this a very big profit? So why did many people recycle this toothpaste tablet at that time? On the one hand, the profit is very considerable. On the other hand, Toothpaste tablets are generally recycled by small vendors in rural areas, and then sold to aluminum products companies, or factories that make pots and bowls for daily use, and some are recycled as aerospace materials by designated units of the state. The recycling places are different, and the prices are naturally different. Normally, they are recycled to formal channels for use. Finally: Toothpaste skin is not very eye-catching, but it was very precious in the past, because it has greatly facilitated our lives. Although we don&;t need it now, we can&;t see it, and we don&;t have to worry about daily necessities, but we should be thrifty and cherish the existing resources. Only in this way can we continue to enjoy the beauty of our present life and develop for a long time.
