Eight kinds and characteristics of industrial cleaning agents

There are many kinds of industrial cleaning agents, and their classification is also very simple. The key is to divide them into organic chemical cleaning liquid and analytical chemical cleaning liquid according to their organic chemical composition. The same cleaning solution has different effects on different stains, or has two or so effects on the same stain, it should be classified according to its key efficacy in general conditions. Types of industrial cleaning agents:

1. Water and non-water organic solvents

The organic solvent of the stain refers to the chemical substance into which the target stain can be removed by melting or dispersing, and there is no smooth and clear organic chemical composition of the new chemical substance. It contains both aqueous and non-aqueous organic solvents.

(1) Water: Water is the existence of nature, are the key organic solvents. In industrial cleaning, water is the organic solvent for most organic chemical cleaners, and it is also the organic solvent for many stains. In cleaning, where tap water can remove stains, there is no need for non-aqueous organic solvents and a variety of preservatives.

(2) non-aqueous organic solvents: non-aqueous organic solvents contain hydrocarbons and halogenated hydrocarbons, alcohols, ethers, ketones, esters, phenols, etc., and compounds in which it is suitable for melting organic chemical stains, such as oil stains and some organic scale.

2. Surface activator (surfactant)

Its molecular structure also has a hydrophilic optically active ester group and a non-optically active lipophilic ester group, when the amount of its addition is very small, that is, it can greatly reduce the interfacial tension of the organic solvent (generally water) and its liquid surface tension, and has the effect of wetting, solubilizing, emulsion, dispersion and cleaning.

Surfactant can be classified in a variety of ways. It is widely classified according to its weak electrolyte in organic solvents and the ionization type of hydrophilic ester groups. Common surfactants are cationic surfactants, positive ionic surfactants, biactive surfactants and non-ionizing surfactants. The first three types are ionic surfactant.

Surface activators are widely used in daily life and industrial production cleaning.

3. Acid-base cleaners

By producing a strong acid and alkali reaction (sometimes accompanied by air oxidation - recovery and other reactions), the stain changes into a detergent that can be dissolved or dispersed in the cleaning solution, mostly citric acid, strong oxidizing agent, alkali and acid or alkali salt after hydrolysis reaction.

Most of the acid-base cleaning agents are composed of acid and base solutions and necessary modifiers. Another type of acid or alkali under high temperature standards for melting conditions and stain efficacy, so that the original does not melt or difficult to melt in the cleaning material stains, converted into easily melted chemical substances, this acid and alkali are generally called melting agents. This type of cleaning agent has excellent practical results for stains that cannot be eliminated with organic solvents or aqueous solutions.

4. Air oxidation - oxidizing agent

The key rely on the chemical reaction with stains to eliminate stains, that is, cleaning with reducing agents or oxidants, including melting agents.

Reducing agents are used to eliminate oxidizing stains, such as many organic chemical stains. Oxidants are used to remove reducing stains, such as rust and scale.

5. Metal material ionization chelating agent

Depending on the ionization of the metal material in the stain to produce a mutual reaction, so that the stain changes into a chelate dissolved in the detergent, such detergent or modifier is the chelating agent. It is commonly used in the cleaning of rust and carbonate scale.

6. Catalyst carrier

Chemical substances that remove stains according to physical adsorption or organic chemical adsorption of stains are catalyst carriers for cleaning. The catalyst carrier with strong appeal to stains should be selected for cleaning.

7. Enzyme preparations

Enzymes are proteins produced by small animals, green plants, and microorganisms that have the ability to catalyze reactions. In the cleaning of stains, it can produce a relative biochemical reaction with organic chemical stains, and promote the dissolution and fall of stains. For example, adding trypsin, lipase, pepsin, cellulase, etc. to the cleaning solution can accelerate the elimination of relative stains.

8. Sterilizing algae and silt stripping agent

Organic chemical drugs that can destroy the bacteria and algae that are cleaned up on the surface and break away from the microbial sludge are bacteria-eliminating algae and sludge stripping agents. It has inorganic and organic chemicals, and inorganic substances are generally oxidants.
