In the city, we often see some vehicles that spray water on the highway. Many people will ask what the effect of such watering is. Sprinklers are an effective tool to maintain the urban environment. Of course, this is just a type of sprinkler . The use of sprinklers is very wide. Let 's take a look.

 

The main uses of the sprinkler trucks are many, such as sanitation, watering, landscaping, cooling and dust removal, and transportation of drought and water, all of which belong to the role of sprinklers. The most common thing on our road is sanitation and watering. Sprinklers can be used for sanitation and sprinkler operations, because the main purpose of sanitation sprinklers is to sanitation and sprinkling operations in cities. This is mainly to sprinkle water on the roads of the city, and also to water the plants in the green belts on both sides of the road. ,

Second, the sprinkler can also be used for cooling operations, especially when the weather is very hot. At this time, the role of the sprinkler is great. It is one of the essential tools for cooling. The sprinkler passes through the pavement and the residential area. Sprinkling water at places such as this can provide a good cooling effect.

Sprinklers can also be used for dust removal. How do you say that when sprinkling water, sprinkled water can deposit dust and tiny particles in the air, which will reduce some of the impurities in the air that harm the human body, not only The health of the human body is beneficial and can also play a role in dust removal. The role of sprinkler is also great when working on landscaping. Because the sprinkler's water cannon can be adjusted into different shapes, and the rear sprinkler and high shower on the sprinkler can also water the roadside green belt, community and the park's flowers and so on, the sprayed water mist can also wash the tree. dust.

5. Sprinklers can be used for temporary firefighting operations. In some emergency situations, they can assist fire engines together. This saves time and reduces losses. The sprinkler's high position sprinkler can be rotated and is very flexible.

Of course there are many uses for sprinklers , but it is an indispensable helper for building green.

Amine & Derivative

One, two, or three hydrogen atoms in an ammonia molecule are substituted with an alkyl group to produce compounds called first amines (primary amines), second amines (secondary amines), and tertiary amines (tertiary amines), respectively. Their general formulas are: RNH2 - primary amine, R2NH - secondary amine, R3N - tertiary amine. Amines are widely present in the biological world and have extremely important physiological effects. Therefore, the vast majority of drugs contain the functional group of amines - amine groups. Proteins, nucleic acids, many hormones, antibiotics, and alkaloids all contain amine groups that are complex derivatives of amines. According to the different types of hydroxyl groups in the amine molecule connected to the nitrogen atom, amines can be divided into fatty amines and aromatic amines. If the amine molecule contains two or more amino groups (-NH2), it can be divided into dibasic amines and terbasamines according to the number of amino groups.

Amines are widely distributed in nature, most of which are produced by amino acid decarboxylation. For example, the industrial preparation of amines is mostly prepared by the reaction of ammonia with alcohol or haloalkanes, and the product is a mixture of amines at all levels, which is purified after fractionation. Catalytic reduction by aldehydes and ketones in the presence of ammonia can also obtain corresponding amines. In industry, amine compounds are often prepared by catalytic reduction of nitro compounds, nitriles, amides or nitrogen-containing heterocyclic compounds

Amines are used for a wide range of purposes. The earliest development of the dye industry was based on aniline. Some amines are necessary to maintain life activities, but some are also very harmful to life, many amine compounds have carcinogenic effects, especially aromatic amines, such as naphthylamine, benzidine and so on.
