Power Plant Descaler Ingredients

Introduction The composition of descaling agents in power plants requires that the main components of descaling agents are weak acids, and there are very strict requirements for these weak acids. Requirements for anti-rust and anti-scaling ingredients:

Power Plant Descaler Ingredients

Requirements for ingredients of descaling agents

The main components of descaling agents are weak acids, and there are very strict requirements for these weak acids. Requirements for ingredients of anti-rust and anti-scaling products:

Hydrofluoric acid

The best effect on silicate scale

Hydrofluoric acid is highly toxic

< p>Mechanism of poisoning

Absorption through mucous membranes and skin can produce toxic effects throughout the body

Primarily toxic to the enzyme system, such as inhibition of succinate dehydrogenase And affects cellular respiration:< /p>

Fluoride combines with calcium in bones or body fluids to form relatively insoluble calcium fluoride, which disrupts the metabolism of calcium and phosphorus, thereby negatively affecting bones and causing osteosclerosis and bone loss. E-mail.

Symptopoisoning symptoms:

Dental erosion, bleeding gums, dry rhinitis, epistaxis, hyposmia, pharyngitis, chronic bronchitis, etc.

Scope of application:

< p>As an important raw material in fluorinated chemical industry, hydrofluoric acid can produce fluorinated refrigerants, fluoropolymers, etc.

It is used for cleaning stainless steel in industrial steel mills

Cannot be used for rust removal and descaling of medical devices

Oxalic acid

Ferrous oxalate produced after the reaction between oxalic acid and rust is insoluble in water

Causing repeated effects

Oxalic acid is toxic

Mechanism of poisoning

Oxalic acid may cause irritation or corrosion of exposed parts

Oxalic acid may combine with calcium to form calcium oxalate, causing hypocalcemia< /p>

In addition, calcium oxalate is mainly eliminated by the kidneys, so calcium oxalate deposits can cause stones in the urinary system and kidney failure

Calcium oxalate can also be deposited. It affects the liver, heart, lungs, blood vessels and other organs, causing abnormal functions of various organs.

Symptoms of poisoning:

Oral pain, ulcers (the mucous membrane may turn white), difficulty swallowing

Symptoms of gastrointestinal irritation such as vomiting, abdominal pain and diarrhea

In severe cases, symptoms such that vomiting blood, hemorrhagic gastritis and blood in the stool and other gastrointestinal bleeding, perforation and shock may occur

< p>Scope of application:

At present , it is mainly used to remove rust from fabrics in China

It cannot be used forr rust removal and descaling of medical devices

Citric acid

When PH>4, rust removal with citric acid will produce citrate precipitation ferric

Causing repeated effects

Applicable scope:

Currently, it is mainly used as a metal rust preventative in industry in China

>It is not recommended to be used for rust removal and descaling of medical equipment

Hydrochloric acid

Very corrosive

Field application:

At present, it is rarely used for metal rust removal in China

It cannot be used for metal rust removal. rust and descaling of medical devices

Phosphoric acid

Phosphoric acid can oxidize trivalent iron ions in rust to divalent iron ions

And ferrous phosphate will not precipitate and rust removal effectwill not be repeated

Phosphoric acid is irritating to the skin and mucous membranes

Scope of application:

For the removal of rust from metals, phosphoric acid treatment is commonly used internationally

Can be used for medical devices Anti-rust treatment and descaling

1. The principle of lemon power generation is to replace the acidic substance of the lemon with a conductive metal part to generate a positive charge and make the bulb glow.

2. Lemon is a juicy fruit rich in citric acid. If two metal conductors with large differences in activity (such as silver, iron, copper, etc.) are inserted into its spaced ends, when both ends of a conductor (iron, aluminum, iron, copper , zinc, etc.) are connected to form a loop, the electrolyte reactionique of the two metals in the acid solution will generate current in the circuit. This is its galvanic cell reaction phenomenon.

< p>3. As long as it contains fruit acid, monocitric acid, amylase and alkaline acidity fruits, a galvanic reaction may occur.

The principle of lemon power generation is: the electrochemical activity of two metal foils is different, such as copper foil and zinc foil. The most active metal foil (copper foil) can interact with the metal foil in the body. fruit. The acidic substance in the fruit reacts chemically to generate a positive charge, and the other piece (zinc leaf) will generate a negative charge. Then a light emitting diode is connected to the two metal parts when current passes through the light. Light-emitting diode, the light-emitting diode is on. In order for the batteries to have a better effect, you pou use several lemons in series as shown below.
