GR-W016 Scale inhibitor for cooking

◼PRODUCT DESCRIPTION

Model   GR-W016:

This product has stable chemical properties in  water and is suitable for water with wide pH value, high alkalinity, high hardness and high concentration multiples; the formula ratio can be adjusted appropriately according to needs during operation. This product can also form a thin and dense anti-corrosion film on the metal surface under high pH conditions, with fast film formation speed and good film repair effect; the reducing substances in cooling water do not affect the corrosion inhibition and pre-filming effects of the product.

Performance characteristics:

The cooking scale inhibitor GR-W016 is composed of multiple active ingredients such as organic phos phonic acid, dis per sant, surfactant , etc .  It  has good corrosion inhibition and disper sibility as well as threshold scale inhibition effect. This product is alkali-resistant and high-temperature - resistant, and has very good scale inhibition performance at a temperature of 200℃ and an alkali concentration of 200g/L.

◼Features

1.Exceptional Resistance to Extreme Conditions: This is its most prominent advantage. It maintains high efficiency and stability under harsh environments with high temperatures (up to 200°C) and high alkalinity (alkali concentration up to 200 g/L), significantly outperforming conventional scale inhibitors.

2.Triple-Action Efficacy:

• High-Efficiency Scale Inhibition: Inhibits scale-forming ions like calcium and magnesium from forming deposits through the "threshold effect."

• Powerful Dispersion: Effectively disperses existing microscopic scale particles in the water, preventing their deposition and adhesion.

• Excellent Corrosion Inhibition: Rapidly forms a dense, self-healing protective film on metal surfaces, effectively preventing corrosion.

3.Broad Adaptability: Possesses outstanding chemical stability and performs effectively across a wide pH range, making it suitable for various water quality conditions.

4.Strong Environmental Tolerance: Its corrosion inhibition and pre-filming effectiveness are not compromised by common reducing substances found in cooling water, ensuring reliability in diverse and complex water chemistries.

5.Operational Flexibility and Cost-Effectiveness: The dosage can be flexibly adjusted based on specific water quality and process requirements, helping to achieve optimal economic efficiency.

◼Typical Applications

1. Pulp and paper industry cooking process: This is its most typical and core application scenario. In the chemical pulping process (such as the sulfate process), the stock liquor is in a high-temperature, high-alkalinity environment, which is highly prone to scaling and equipment corrosion. GR-W016 can effectively address these challenges.

2. Other industrial circulating cooling water systems with high temperature and high alkalinity: For example, in industries such as chemical, petrochemical, and metallurgical, specific production stages may generate circulating water with high temperature and alkalinity. GR-W016 is an ideal choice for such systems.

3. Boiler systems or process heating systems with extremely high requirements for scale and corrosion inhibition performance: This is particularly relevant for systems whose operating parameters (temperature, alkalinity) approach the performance limits of the product.

◼Why can GR-W016 remain effective at high temperatures up to 200°C? What is the principle?

This benefits from the unique molecular structure of its core component—organic phosphonates. This structure possesses extremely high thermal stability, as the carbon-phosphorus (C-P) bonds within the molecule are not easily broken under high temperatures. Meanwhile, the compounded dispersants also remain active at elevated temperatures. Together, they prevent the formation and growth of scale crystals through mechanisms like lattice distortion and dispersion.

◼What does the "Threshold Scale Inhibition Effect" mentioned in the product description mean?

The "Threshold Effect" refers to the phenomenon where GR-W016 is dosed at a concentration far lower than the chemical equivalent of the scale-forming ions in the water, yet it still exerts a highly efficient scale inhibition effect. Its molecules adsorb onto tiny scale crystal nuclei, inhibiting their further growth, or disrupt the crystal's normal structure, making it loose and easily washed away by water flow. Thus, a small amount of the chemical can control a large quantity of scale-forming ions.

◼How does this product achieve both scale and corrosion inhibition simultaneously?

Scale Inhibition: Relies on the chelation/threshold effect of organic phosphonates and the dispersing action of the dispersants. Corrosion Inhibition: The organic phosphonate molecules can form a strong, protective adsorption film on metal surfaces, isolating corrosive agents like water and oxygen. Particularly under high pH conditions, this film forms faster and more densely, achieving synergistic protection.

◼What are its main applicable industrial scenarios?

It is specially suitable for harsh condition systems, such as: digester vessels in the pulp and paper industry, industrial cooling water systems operating under alkaline conditions, feedwater systems for high-temperature boilers, and sections like alkali recovery evaporation stations where high alkalinity, high hardness, and high temperature conditions exist.

◼Will the use of reducing agents (e.g., sodium sulfite) in a system affect the performance of GR-W016?

Basically, no. The product is specially designed so that its corrosion inhibition and film-forming functions are insensitive to common reducing substances (like sulfite ions) in cooling water. It demonstrates good chemical compatibility, ensuring stable performance in complex water quality conditions.
