1、 Product Description

Calcium scale cleaner is a medium strong acid cleaner with the characteristics of non-volatile, odorless, and non-toxic to the human body. Its aqueous solution can quickly and effectively remove scale and corrosion products on the surface of equipment made of materials such as iron, steel, copper, stainless steel, etc.

2、 Product Features

Suitable for cleaning circulating water, boiler water, air conditioning condensers, and plate heat exchangers

Low foam formula

Liquid medicine can shorten the mixing time.

At room temperature and under dry conditions, solid pharmaceuticals do not absorb moisture and have stable properties.

3、 Physical characteristics

Status: Thick liquid Appearance: Colorless transparent or slightly light yellow.

Solubility: soluble in water Volatile: non-volatile

Specification: Industrial use (85%, 80%, 75%), in compliance with GB2091-2003

4、 Application

Calcium scale cleaner is a medium strong acid cleaner suitable for various water systems. This product can quickly and effectively remove dirt deposits in the system and purify metal surfaces. A 3% aqueous solution of this product can dissolve calcium deposits, disperse them in the system, and discharge them through sewage displacement. The disadvantage is that there is a certain degree of corrosion to the material during system cleaning, and adding corrosion inhibitors can effectively control the corrosion rate. Suitable for materials such as copper, PP, PVC, PVDF, etc.

5、 Operation precautions

Wear appropriate gloves and eye masks. In case of eye damage, immediately rinse your eyes with plenty of water and seek medical attention from an ophthalmologist. If it overflows, it should be removed by absorbing sand or other absorbent substances, and then rinsed with clean water afterwards.

6、 Packaging and Storage

Calcium scale cleaning agent is packaged in plastic drums with a net weight of 35 kilograms per drum. The storage period is more than one year.

Application principle of boiler quick acting descaling agent:

When the concentration of silicate phosphate based drinking water treatment agents in water is about 3-5 ppM, soluble complexes and insoluble nano scale membranes are formed to prevent scale and corrosion, effectively preventing secondary pollution. The metal ions such as calcium (Ga), magnesium (Mg), and iron (Fe) contained in water are prone to form insoluble substances such as calcium carbonate and magnesium carbonate on the inner wall of water supply pipelines. Polyphosphate in drinking water treatment agents can react with these metal ions to form soluble complexes, inhibit the formation of calcium carbonate and magnesium carbonate, and disperse into the water. After reacting with iron ions, a dynamic protective film is formed on the inner wall of the pipeline to prevent corrosion and prevent scaling.

1. The mechanism of preventing water scaling, corrosion, and "red water" in silicon phosphorus crystals:

The scale inhibition mechanism of silicon phosphorus crystals: ① It can prevent the formation of CaCO3 crystal nuclei; ② Can prevent the crystal growth of CaCO3; ③ It can disperse CaCO3 crystals and hinder their aggregation together. Due to the above three functions, CaCO3 will not precipitate on the surface of the heat exchanger and in the pipeline system, and its function is equivalent to "softening".

2. The mechanism of preventing corrosion and "red water" in silicon phosphorus crystals:

Main mechanism: ① Polyphosphate in silicon phosphorus crystals can bind with divalent ferrous hydroxide (known as blocking), which can prevent the conversion to trivalent Fe (OH) 3 and Fe2O3, eliminating the root cause of "red water" production. ② The dispersing effect of polyphosphate in silicon phosphorus crystals on Fe (OH) 3 inhibits the occurrence of "red water" during the cleaning process of existing rust. It can disperse soft rust blocks and make them fall off on the metal surface. ② The silicates in silicon phosphorus crystals can form a thin silicon film on the surface of rust, controlling the amount of rust that falls off and allowing the trace amount of rust to become transparent water and be discharged from the system under the dispersing effect of polyphosphate. Due to the action of silicon phosphate, it can form a silicon film on the metal surface, isolating dissolved O2, CO2, CL - and other chemical reactions in water from the metal surface, thereby preventing further corrosion of the metal. Its function is equivalent to that of a metal lining.

Supply from Beijing quick acting descaling agent manufacturerOne prominent feature:

Solid boiler descaling agents (boiler descaling powder) are organic acid series cleaning agents composed of various substances such as descaling agents, corrosion inhibitors, accelerators, masking agents, fog suppressants, surfactants, etc. Practice has proven that this technology has high descaling efficiency, fast cleaning speed, minimal corrosion to metal substrates, and has a passivation effect on metals during the cleaning process. Therefore, there is no over washing phenomenon, and the passivation film is dense and complete after cleaning. This product does not contain toxic or harmful substances, so it is safe to use, pollution-free in waste liquid, safe and environmentally friendly. The usage method is simple and easy to master. The promotion and application of boiler descaling powder provides a guarantee for the safe and efficient operation of boilers.

Two usage methods:

1. Chemical cleaning process: water rinse, acid wash, descaling, water rinse, passivation treatment;

2. Disconnect other systems unrelated to the boiler and connect the cleaning tank, cleaning pump, and boiler into a closed cleaning circuit;

3. Check the leakage of the cleaning system under simulated cleaning conditions, and remove loose dirt from the boiler. When there are no large particles or impurities in the flushing water at the outlet, the water flushing is completed;

4. After the water flushing is completed, circulate and add "boiler cleaning powder" in the cleaning tank, control the concentration of the main cleaning agent at 36%, and maintain the temperature within the range of 5060 ℃. Perform circulating cleaning and decontamination in the system for about 23 hours. Regularly measure the pH value of the acid solution using pH test strips (once every 20 minutes), keeping it below 1. When the pH value stabilizes within half an hour and there is no gas released from the cleaning system, the acid washing process is terminated;

5. After passing the water flushing, circulate and add "passivation pre film agent" for passivation treatment to improve the corrosion resistance of the boiler. After the concentration of the entire system solution is evenly mixed and heated to around 60 degrees, stop circulating and soak for 23 hours. Drain the passivation solution from the system and end the cleaning process.

Three precautions:

1. Boiler descaling powder cannot be consumed;

2. Wear personal protective equipment during the handling and operation of boiler descaling powder.

Four packaging specifications:

Plastic bags: 1 kg/bag, 25 kg/bag.
