Beijing quick acting descaling agent manufacturer for sale

The dosage of quick acting descaling agent should be determined based on the amount of scale. Generally, 1 kilogram of descaling agent is required to remove every kilogram of scale. It can also be calculated according to the formula: dosage (kg)=1.5 scaling thickness (mm) × heat exchange area (m2), and the concentration of the prepared cleaning solution generally does not exceed 10%. The method of multiple dosing can also be adopted, and the reaction situation can be observed at any time until the scale is completely removed when the pH value is 1-1.5. The method of descaling can be immersion or forced circulation. The temperature of the descaling agent should be controlled at around 40 ℃ -60 ℃. Low temperature results in slow reaction rate and long cleaning time; As the temperature increases, the reaction rate accelerates and the cleaning time shortens. However, if the temperature exceeds 60 ℃, it will cause the effective components in the descaling agent to decompose and lose their descaling ability. Therefore, it is necessary to control it at around 60 ℃. The cleaning time is generally 8 hours. For boilers with thick scale, it can be extended to 24 hours. After soaking, heat up and boil, and it can be discharged in 1-2 hours. To prevent boiler corrosion, a 1% solution of trisodium phosphate should be added to neutralize and purify the passivation solution discharged from the boiler, and then rinsed with clean water. The boiler can be put into operation or maintained for future use. The amount of descaling agent should be determined based on the amount of scale.

It can also be calculated according to the formula: dosage (kg)=1.5 scaling thickness (mm) × heat exchange area (m2), and the concentration of the prepared cleaning solution generally does not exceed 15%.

Scope of application of cleaning agents for circulating water system operation:

This product is a neutral operating cleaning agent for industrial cooling circulating water systems. It can dissolve and remove scale, mud, and mixed rust deposits on the metal surface of the heat exchange equipment in the circulating cooling water system under normal operating conditions. Used for various industrial circulating cooling water systems in normal operation, to clean the scale and adhesive sludge on the metal surface of heat exchange equipment. Used for cleaning floating rust, mild rust scale, scale, and sludge scale formed on the surface of heat exchange equipment during shutdown.

Performance characteristics:

High cleaning efficiency: It can effectively dissolve the scale, rust and other dirt adhered to the metal heat transfer surface of the heat exchange equipment in the circulating water system, disperse them in the cooling water, and discharge them out of the cooling water system through sewage, thereby restoring the original heat transfer performance of the heat exchange equipment and maintaining the clean, efficient and low-energy operation of the circulating water system.

Safe and non corrosive: complete descaling and cleaning under neutral conditions, without changing the normal operating conditions of the cooling circulating water system during the cleaning process. No corrosion damage to metals, effectively avoiding strong chemical and electrochemical corrosion damage to system equipment metals caused by acid washing, especially effectively preventing intergranular corrosion damage to stainless steel equipment caused by acid washing. This greatly extends the service life of the heat exchange equipment and significantly reduces the daily maintenance costs of the cooling circulating water system.

Easy operation process: The cleaning agent can be directly added to the cooling circulating water system for normal operation, and there is no need to add additional cleaning auxiliary facilities to complete the descaling operation.

Physical and chemical properties:

Appearance: Light yellow liquid; Water solubility: soluble in water;

Density: (20 ℃), g/cm3：≥1.05； Flammability: Non combustible

Usage:

Calculate the total dosage based on the capacity of the circulating water system (the amount of water retained by the system during normal operation), and select the dosage ratio according to the amount of scaling in the heat exchange equipment of the circulating water system. Add 3-5 kg of this product per ton of water. Add 60% of the total dosage to the system at once, and discharge once after 10-15 days of normal operation, with a discharge rate of 15-20%. After discharging, add all remaining medication to the system and operate normally for 20-30 days. After the cleaning is completed, if the system water is turbid, it can be replaced and discharged through the collection tank in a continuous water replenishment state by adding water while discharging, until the system circulating water is clear and transparent (conductivity and turbidity return to normal values before cleaning).

Beijing quick acting descaling agent manufacturer for saleNotes:

This product has no dissolution effect on magnetic iron oxide (Fe3O4). When the biological sludge is severe, using a sludge stripping agent for cleaning can achieve satisfactory cleaning results. When there is oily dirt in the circulating water system (such as oily organic liquids or gasoline/diesel leaks into the circulating water system, or severe oil leakage from the compressor), it is necessary to use oil cleaning agents to clean the oil dirt in order to achieve the desired cleaning effect. When the circulating water system experiences severe leakage and loss, the leakage point should be eliminated first to restore the system to normal water replenishment, and then this product should be added for operation and cleaning. Packaging and storage: 20kg, 25kg plastic drums. Store in a cool and dry place, with a shelf life of two years.
