Does the material of the trash can react chemically with some trash?

The material of the trash can is generally polyethylene (PE);

Polyethylene has good low temperature resistance (the minimum use temperature can reach -70 -100), good chemical stability, can resist the erosion of most acids and alkalis (not resistant to acids with oxidizing properties), and is insoluble in any known solvent at room temperature; However, because it is a linear molecule, it can be slowly dissolved in some organic solvents, and has poor heat aging resistance; Therefore, more than 70 can be dissolved in a small amount in toluene, amyl acetate, trichloroethylene and other solvents.

As for other toxic and harmful waste, such as substances containing strong acids and alkalis, they will generally only appear in the enterprise, and this should be collected according to the requirements and asked by qualified institutions to carry out **.

In general, only the garbage reacts biologically in the trash can. Plastics are very difficult to react with these substances.

Generally speaking, it's difficult.

If it is a plastic bucket, many of the materials sold on the market now are polymer materials, and it is difficult to react them (ignition does not count).

In the case of metal barrels, it is difficult to say. In general, there are many daily necessities that contain acid. Like detergent.

These can be displaced-in with the walls of the barrel and corrode the walls of the barrels. However, although acids such as oxalic acid and citric acid are also contained in fruit peels and rotten vegetables, they are weak in acidity and difficult to cause great corrosion.

Look at me typing so many words, let it go.

It is possible to react with some special liquids, but it will not react with ordinary garbage.

Common trash can materials tend to be plastic.

In addition to being afraid of fire, plastic is very stable at room temperature and is not easy to react with other substances.

Buried garbage cans, Pengchuang environmental protection said that there are cold-rolled plates, galvanized sheets, stainless steel and other materials, stainless steel has, 304 ** is more expensive, but the service life is very long, buried in the ground for a few years, it will definitely be affected by corrosion and shorten the service life. The main thing is that it's important to find the right thing to do. You can ask us.

Most of the buried trash cans are made of FRP, which is corrosion-resistant, will not rot, and has a long service life.

1: Sanitation workers, they will never go to see it, because they are very tired, very annoying, and not in the mood. Will only prioritize their own work.

2: The general garbage ** person, don't look at it, or don't look at it carefully, it's generally just to take it away after two glances, and then sell it.

3: People who are idle and bored. There will always be a small number of garbage ** people who will be idle to look at certain things, such as things that look like notebooks......

In general, everyone pays more attention to their work, and they are less likely to find trouble for themselves or those they don't know. So only a very small number of people will view spam.

Well, I even admit that I will look at the contents of the trash can, and then associate and analyze something, but it is also a ...... that passes in an instant and does not delve into it）

Who knows, some people may watch and some people won't. Look at him and he's not interested.

They only classify resources** and resources, and should look at which category they belong to, and will not look at them in detail.

Obviously not, because you don't have bird flu yourself, and there are other viruses in the trash can that can be infected with bird flu.

Don't worry, it's a blessing or a curse, it's a curse that can't be avoided! Your own vomit, are you sure you have bird flu? Are you overly cautious, sensitive, and don't feel tired of living like this? Relax, exercise, and increase nutrition are the basics of resisting diseases!

Drop the things in the trash can, and be willing to pick it up to show that this thing still has the meaning of existence, the trash can itself is just a person who gave it a name, not the starting point of bad luck, good luck!

This is a purely legal issue. First of all, this is not a constitutional provision, but should be found in the civil law. Trash cans, as they are known, are places where garbage is stored.

Garbage, on the other hand, is legally discarded. In the first case, if the perpetrator picks up the discarded items in the trash can, he does not have to return them. Because the property right of the discarded object has been abandoned by the user, the act of picking up the garbage by the picker is the re-establishment of the property right of the unclaimed property.

In the second case, if someone accidentally throws it into the garbage can, or the thief steals something and puts it in the garbage can, then the real right of the thing has not disappeared and is still in the possession of the original owner. At this time, the perpetrator picks up the item in the garbage can, and the owner of the property right has the right to apply for return, and failure to return it is unjust enrichment or infringement. Third, if the positioning of the garbage bin itself is not accurate, some people think that it is the place of the item, and some people think that it is the garbage can, and there is a dispute as a result, then the property right will not disappear.

This ** is purely pretending, no matter how rich he is, he is not as capricious as him.

Absolutely, I will eat it if I don't take it back.

Isn't this a rich and white show? Do you want to envy us to death?

I don't know your level of knowledge, I will say several (matter is composed of molecules, molecules are composed of atoms) (1) The reaction of matter generally changes from unstable to stable, from orderly to chaotic, such as combustion, **, etc.

2) Generally, the outermost shell of the atom is most stable when there are two or eight electrons, such as a metallic element, the outer shell of the atom has an electron, a non-metallic element, the outermost shell of the atom has seven electrons, which is easy to react when the metal and the non-metal are together, and the two atoms together 1+7=8 constitute a stable substance. That is, the substance is oxidizing and reducing.

3) There is a Gibbs free energy formula, g=h-ts, g<0 can react, s>0 when the temperature t rises to a certain value, the reaction can occur.

Don't be afraid.

Purdue is very good to record.

Even if the project is on 85, it is easy to say.

As long as your GPA, EC, etc. are slightly better.

Some even say that purdue is hardly rejected.

And also. Don't email Purdue.

I sent 3 questions asking if the materials had been sent.

It ignored me all the time.

Finally, one day, I saw that the status was recorded.

One of my classmates sent him a letter and he didn't reply.

Because the people of his family are very angry, and they also ignore people.

That's all, lz, have faith that AD will have.

Message me if you have any questions.

msn is not easy to write here.

My friend applied for UIUC, and he was also a few points behind, and he was admitted to conditional admission.

The situation is different for each family, and the situation is different from year to year. It depends on whether the major is full, or whether your other conditions are more prominent

Like what I said upstairs, I'm really worried about it, so I'll talk to the secretary

You should ask this question in studying abroad...

Well, send an email to the admissions committee and tell them about your situation, and you should get back in two days at most.

Based on past experience, there is no problem, and I will not want you because of these three points. It depends on how well you write your email.

Do you want to Shen Pudu too?

Me too, can I talk about it.

Are you a graduate student, and what major?

It depends on whether the school you are applying to is full, and if there are still places, you will be considered.
