N-methyl-2-pyrrolidone (nmp) is an organic compound consisting of a 5-membered lactam. It is a colorless liquid, although impure samples can appear yellow. It is miscible with water and with most common organic solvents. It also belongs to the class of dipolar aprotic solvents such as Dimethylformamide and dimethyl sulfoxide. It is used in the petrochemical and plastics industries as a solvent, exploiting its nonvolatility and ability to Titanium Dioxide dissolve diverse materials.
Nmp N-methyl-2-pyrrolidone Solvent is used to recover certain hydrocarbons generated in the processing of petrochemicals, such as the recovery of 1,3-butadiene and acetylene. It is used to absorb hydrogen sulfide from sour gas and hydrodesulfurization Solvent Raw Material facilities. Its good solvency properties have led to NMP's use to dissolve a wide range of polymers. Specifically, it is used as a solvent for surface Pvc Resin treatment of textiles, resins, and metal coated plastics or as a paint stripper. It is also used as a solvent in the commercial preparation of polyphenylene sulfide. In the pharmaceutical industry, N Methyl-2 Pyrrolidon is used in the formulation for drugs by both oral and transdermal delivery routes.

The sorting of rubbish is actually very necessary. The necessity is mainly reflected in the fact that it can make the rubbish truck garbage cleanup work more regular. As a result, there are many benefits for the garbage truck. In this kind of work, how should we do it? Here, the author needs to talk about such a problem.
First of all, we should separate recyclable garbage from non-recyclable garbage. In this way, the processing of garbage can be started from this road. Such a classification can also be used to effectively use resources. Therefore, this is very important. It is necessary.
Then we need to separate those wastes that have pollution and no environmental pollution. Of course, there are good reasons to choose to separate them. One is to sort garbage, and the other is to keep the environment clean.
The sorting of rubbish requires us to know the skills, and the effective processing can produce good results. Therefore, it is very necessary for us to know how to deal with it so that we can build a better home.
The correct use of garbage trucks is a key part of the garbage disposal process, because the work will only become easier if it is used correctly. In this way, the environment around us will also appear to be cleaner. When it comes to the proper use of garbage trucks, we have to talk about garbage sorting.
