At the same time, it is recommended that you do not throw away the discarded key, it has many other uses, and it may come in handy one day.

What kind of garbage does the discarded key belong to?

The key is a tool that we often use to unlock the lock in our lives, and there are many types of keys, in addition to the ordinary keys we use every day, there are remote control keys, smart keys, electronic keys, etc., but the longest is still an ordinary key, a lock corresponds to a key, but sometimes the lock is changed, the key is useless, it will be lost, so what kind of garbage does the waste key belong to?

First of all, the key to waste is a garbage, but the garbage refers to the garbage that can be recycled, and the garbage that can be sold as a waste product has the value of the gods, and is generally divided into five categories, such as plastic, paper, cloth, metal, and glass, and the key we use every day is made of copper, zinc, aluminum, iron and other metal materials, which is just in line with the metal, so it belongs to the garbage.

Secondly, since the key is a useful item, what can we do with it? If you are a lover of crafts, then you can decorate your crafts with keys. When you can't find the bottle opener when you drink beer, you can use the key to open the beer cap.

When you can't tear the courier tape at home, you can use the key as a knife to cut it.

Discarded keys are trash. Garbage refers to: renewable and recycled garbage, popularly speaking, it is valuable garbage that can be sold for waste, mainly divided into five categories: paper, plastic, glass, metal, cloth, etc.

From the perspective of the methods of domestic waste classification in foreign cities, they are generally classified according to the composition and amount of garbage, combined with the resource utilization and treatment methods of local garbage. For example, Germany is generally divided into paper, glass, metal and plastic; Australia is generally divided into compostable garbage, which can be **garbage, and non-**garbage; Japan is generally divided into plastic bottles, liftable plastics, other plastics, resource waste, large garbage, combustible garbage, non-combustible garbage, hazardous garbage, etc.

Discarded keys are trash.

Keys are generally metal products, and this kind of key can be rebuilt into other useful items, and the plasticity of metal is strong, so the key is planned into the garbage.

It mainly includes five categories of domestic waste, including waste paper, plastics, glass, metals and textiles, three categories of special hazardous waste, hazardous waste, electronic and electrical waste and batteries, as well as waste furniture waste.

1. Waste paper. Newspapers, magazines, books, various wrapping papers, office paper, cartons, etc., but paper towels and toilet paper are too water-soluble.

2. Plastic. All kinds of plastic bags, plastic packaging and tableware, toothbrushes, cups, mineral water bottles, plastic toys, plastic stationery, plastic daily necessities, shampoo bottles, hand sanitizer bottles, laundry detergent bottles, dish soap bottles.

3. Glass. Glass beverage bottles, glass wine bottles, broken glasses, broken glass windows, waste glass plates, lenses, mirrors, etc., according to the ** process, glass is divided into colorless glass, green glass, and brown glass.

4. Metal. Cans, metal cans, decorations, aluminum foil, iron sheets, iron nails, iron pipes, scrap iron wires, old steel wool balls, copper wires, etc., are classified according to ** materials: iron, non-ferrous (generally non-ferrous metals).

5. Textiles.

Discarded clothes, pants, socks, towels, school bags, cloth shoes, bed sheets, bedding, plush toys, etc.

The lock cylinder can be replaced, and the official key can be prepared because of the discarded decoration key.

Friends who have experience in decoration generally know that the new door lock is equipped with two sets of keys, A and B, namely "decoration key" and "owner's official key". The owner hands over the renovation key to the decorator; After the house is installed, and then use the official key to activate the lock cylinder, and the decoration key can not be used.

The difference between A and B keys is only a difference in the key head, so it is best to change the lock cylinder.

The marble chamber in the pit corresponding to the different depths of the A and B keys has a special structure and is equipped with a 1mm steel ball between the upper and lower marbles. When the A key is used, the height of the lower marble in the marble chamber plus the height of the small steel ball is just flush with the lock cylinder, so the A key can be used to twist the lock cylinder to unlock the lock; When using the B key, just the small steel ball can be pushed out of the lock cylinder, that is to say, the lower bead and the lock cylinder are flush at this time, so the B key can also be twisted to unlock the lock cylinder (this principle is the same as the key system), but when the lock cylinder rotates at a certain angle, the small steel ball will be affected by the action of the upper marble spring, and fall into the blind hole that is cleverly designed on the lock cylinder in advance (this is the difference with the key system), some people call this small blind hole a trap, very appropriate. The diameter of this blind hole is larger than the small steel ball, but smaller than the diameter of the marble, otherwise the marble will fall and the lock cylinder will be stuck and cannot be unlocked.

Once the small steel ball falls into the blind hole, it can only rotate with the lock cylinder, and will not run out of the blind hole, which will not affect the use of the B key, but because there is no small steel ball when using the A key, the lower ball in this marble room can not be flush with the lock cylinder (the height of the small steel ball), and the lock cylinder cannot be unlocked.

You're level 9 and you're still asking such a naïve question. Otherwise, you don't have to separate, you keep using it; If you don't worry, change the lock cylinder.

I really can't handle it, take a plane to the beach and throw it in the deep sea!

I don't know if you have the kind of old keys that are no longer used in your home, I believe that most families have several, such as locks after the new ones, etc., will leave a few old keys, which are useless.

Some people may put the old key in a place, and some people may throw it away, after all, it is useless except, there are too many waste keys, and it is easy to get confused, but what I want to tell you today is that in fact, the waste key is also very useful, and many places actually hold a waste key in hand, it can be much easier, and you can save buying tools.
