What is the corrosion inhibitors, their types and usage rules

Under the influence of external factors, all materials in one degree or another change some of his properties.One of them, directly influencing the destruction of the structure of substances, are fluid.When we talk about corrosion, then basically mean the contact of different parts or elements of construction with water (or fluids containing it), although there are other types of it - E / chemical, gas and the like.Such contact can be not only straight (wetting), but also indirectly.For example, in conditions characterized by excess moisture.

All substances that have a negative effect on the material, called aggressive, and the degree of influence (failure rate), divided into strong, medium or weak action.Naturally, to extend the life of the product is necessary to take care of their effective protection.

following most common methods:

• application of protective films (polymers and a number of other chemical compounds);
• surface layer treatment is more "sustainable" metal;
• cement coating (eg, pipes utilities - sewer, water and so on);
• coloring enamels;
• E / chemical treatment to form a layer of phosphate;
• priming spetssostavami.

There are other, more costly methods.For example, doping.Many of them are only applicable in the workplace, as they require the use of appropriate equipment and a sophisticated technology.

inhibitors - it

In the "private" sector master limited opportunities.Therefore, in many cases preferable to reduce the aggressiveness of the environment by means of special connections.Such substances are called "inhibitors" of corrosion.Advantages

method

1. Easy to use.
2. Transactions may be performed without the use of expensive equipment and at all stages of construction or repair.
3. Economy.

We will not burden the reader reading the descriptions of all the nuances occurring chemical processes.For general information, we note only that the corrosion inhibitors are divided into absorption and passivation.In practice, the function of the protection of metals or some means of one or more (mixture).

Types inhibitors

• for acidic environments;
• from atmospheric influence;
• against corrosion hydrogen sulfide;
• for storage and highways with oil;
• for neutral media.

In turn, all the groups have "internal classification."For example, agents are classified into organic and inorganic volatiles;mixed, anode or cathode.

Regardless of their chemical composition, the same means differently behaves in some corrosive environments.

Key Features

1. Pour.
2. viscosity.
3. density.
4. solubility.
5. temperature "flash."

Where can be used

corrosion inhibitors is necessary to remind the reader that the term "corrosion" is applied not only to metals.Degradation caused by corrosive chemicals subject to, for example, ceramics, polymers and other materials.But in this case it is customary to use the word "aging".

Scope

We will not consider the use of inhibitors on a commercial scale.It is well aware of specialized experts.They even added to lubricants to minimize the activity of an aggressive environment.We note only those "constructive elements," which can be protected by special means in the "private" sector.

• pipe line, especially sites, laid on the territory (outside the building).
• Septic tanks, tanks that are made of metal.
• roof, walls, basement.
• heating systems.To prevent internal corrosion (or "rust" - there is such a term) of pipes and radiators.

product range is quite large.Here are some varieties of commercially available tools.

«inhibit»

used to protect many metals and alloys.It is advisable to handle the design, operating at excessive humidity, even at temperatures below 0 ° C (-40).After application forms a thin film.Before use, dilute nearly all available solvents - toluene, mineral spirits and a few others.

Price for the package - from 245 rubles.

«RE-Therm»

considered a universal remedy, since the use of a very broad spectrum - from the processing of roofing and pipes (ducts) to detail (eg, the bottom) of personal car.The solvent is ordinary water.

price - from 480 rubles.
