Instructions from ChimEx on registering in the Saturn system
Description
In the summer of 2022, the Government of the Russian Federation launched a pilot project for tracking the movement of agrochemicals and pesticides, under which all suppliers and consumers of these products are required to register in the Saturn system and submit information...
The main types of fertilizer are based on nitrogen as the most important plant nutrient element. This is because it is part of the amino acids in proteins.
In addition to nitrogen, oxygen, carbon and hydrogen, as well as phosphorus and sulfur, form the basis of living tissue and organic matter. While the first three are available from the...
Carbamide (Urea) is the most commonly used solid nitrogen fertilizer.
In nature, it occurs naturally in the urine of animals.
Urea is usually spread over the field, and plants break it down to absorb ammonia and ammonium.
This fertilizer moves fairly easily through the soil together with water. Leaching of the fertilizer depends largely on...
The first fluorine compound known to science was fluorspar (calcium fluoride) — mentioned at the end of the 15th century. At that time it was called "Fluor", and the property known to science was its ability to lower the melting temperature. This property was extremely important for smelting ore and making glass. Of huge importance for the...
Fluorine chemistry - a history of discovery
For more than 70 years, fluorine compounds have been used in the chemical, electrical, aerospace and other industrial fields. In technological processes, relatively few (natural, for example cryolites) metal fluorides and their compounds were used historically. Before that, attempts to obtain elemental...
Product packaging
All transported goods must have proper packaging (container), the type of which depends on:
The type of the goods themselves (cargo may have no packaging at all — for example, when sold in bulk); this also includes special characteristics of the cargo — food product, dangerous and so on;
The type of transport by which...
Paraffin for candle production.
Petroleum paraffins are divided into grades:
Food grade P2
Technical (grades T1 and T2)
Match grade NS
Food-grade paraffin P-2 is used for coating food products, fruit, etc., as well as for technical purposes. It is white in colour. It is packaged either as shavings in 20 kg bags or as whole pieces of 5-20...
The entire soap-making process is usually divided into two types:
Chemical stage — direct soap making.
Mechanical stage — additional processes take place in it, such as drying, introduction of fragrances and so on.
Chemical stage:
First, a mixture of various fatty acids is prepared (in some technologies resin and/or naphthenic acids are...
Methods for processing ash waste from thermal power plants.
When thermal power plants (TPPs) operate, burning coal produces a large amount of ash and slag combustion residue. Such residues can be conditionally divided into heavy (slag) and volatile (fly ash). About 80% of the mineral component of coal turns into the volatile fraction, which is...
Metal treatment against rust
There are several ways to clean metal from rust
The mechanical method involves mechanical action on the surface by hand or with special equipment. Sandblasting is the most effective method for mechanically removing rust.
The chemical method consists of chemical action on the metal. Acids are used:...
