Haolang Cleaning Prefilming Agent is a compound of chemicals with chelating, cleaning, dispersing, and filming functions. It serves dual purposes of cleaning and prefilming, offering advantages such as fast cleaning speed, excellent cleaning effect, rapid film formation, dense and uniform film, and low corrosion rate. The cleaning prefilming agent has strong adaptability to various water qualities and is not affected by harmful ions like iron and copper in water. It is suitable for cleaning and prefilming in circulating cooling water systems, especially for online cleaning and prefilming in circulating water systems.
I. Physical and Chemical Properties:
Item | Specification |
Appearance | Amber liquid |
Solid Content % ≥ | 40.0 |
Total Phosphorus Content (as PO?3?) % ≥ | 20.0 |
pH (1% Aqueous Solution) | 2.0±1 |
II. Usage Instructions
The dosing concentration for online neutral cleaning prefilming agent is generally 1000-3000 ppm. After adding the agent based on the system water volume, start circulation. The endpoint is reached when the water becomes clear after 24-48 hours.
Operational Precautions:
This product is weakly acidic. Pay attention to labor protection during operation, avoid contact with skin and eyes, and rinse thoroughly with plenty of water if contact occurs.
Prefilming Agent
Product Overview:
The prefilming agent can form a dense film on metal surfaces such as carbon steel and copper.
It features fast film formation, fine and uniform film quality, good chemical stability, and low corrosion rate.
The prefilming agent has strong adaptability to water quality and is not affected by harmful ions like copper and iron in water.
Technical Parameters:
No. | Item | Specification |
1 | Appearance | Colorless transparent liquid |
2 | Density, g/cm3 | 1.05~1.25 |
3 | pH | 2.0~6.0 |
4 | Water Solubility | Completely soluble in water |
Product Characteristics:
1. The prefilming agent is mainly composed of various complexing agents, dispersants, filming agents, and surfactants.
2. It forms a layer of insoluble chelated film on metal surfaces such as carbon steel. This film has high resistance and isolates the metal from corrosive media in water, thereby inhibiting corrosion.
3. The prefilming agent is primarily used for prefilming heat exchanger equipment and pipelines in new circulating cooling water systems or after system maintenance. It forms a protective film on metal surfaces to prevent corrosion of materials such as carbon steel, copper alloys, and stainless steel during system operation.
Usage:
The dosing concentration of the prefilming agent is generally 200~600 mg/L. The prefilming time is 48-72 hours under cold conditions and 24-48 hours under hot conditions. The proper treatment level depends on many factors. Our technical personnel will help determine the dosage for specific situations and provide detailed usage instructions.
Storage:
Store in a cool, ventilated place, avoid direct exposure to sunlight, and avoid freezing.
Packaging:
25 kg/plastic drum or as per customer requirements.
Safety Protection:
The prefilming agent is weakly acidic. Pay attention to labor protection during operation, avoid contact with skin and eyes, and rinse thoroughly with plenty of water if contact occurs.
