PRODUCT IDENTIFICATION INFORMATION

CHEMICAL STRUCTURE

    SurTec® 177 Composition
    
    Main Components:
    
    1. Sodium Hydroxide (NaOH)
       Na⁺ + OH⁻ → Alkaline medium, saponification
    
    2. Silicates (Na₂SiO₃)
       SiO₃²⁻ + H₂O → Protective film, buffering
    
    3. Carbonates (Na₂CO₃)
       CO₃²⁻ + H₂O → pH buffering, water softening
    
    4. Surfactants (Non-ionic)
       Surface tension reduction, wetting, emulsification
    
    Ionic Structure:
    Na⁺ + OH⁻ + SiO₃²⁻ + CO₃²⁻

Key Functional Groups:

• Alkaline medium: Provides cleaning power through saponification and emulsification

• Silicates: Provide buffering and protective film formation

• Carbonates: Provide pH stability and water softening

• Surfactants: Provide wetting and emulsification

SECTION 4: APPLICATION AREAS

SECTION 5: BATH PREPARATION

Step-by-Step Instructions:

1. Fill the tank with approximately 2/3 of the required volume with water.

2. Add the required amount of SurTec® 177 powder (60-80 g/l) slowly while stirring.

3. Stir vigorously until complete dissolution is achieved.

4. Top up to the final volume with water.

5. Heat to operating temperature (20-40°C).

6. Check pH (should be ~13).

7. Check conductivity – should be suitable for electrolytic cleaning.

Example Bath Preparation (1000 L):

• SurTec® 177: 60-80 kg (60-80 g/l)

• Water: To 1000 L

SECTION 6: BATH ANALYSIS AND CONTROL

Sampling Procedure:

1. Take a homogeneous sample from the bath while stirring.

2. Cool to room temperature.

3. If the sample is turbid, allow turbidity to settle, then filter or decant the solution.

Titration Analysis:

Equipment:

• 1 mol/l hydrochloric acid (HCl) or 0.5 mol/l sulfuric acid (H₂SO₄)

• Methyl orange indicator solution (0.04%)

• 250 ml Erlenmeyer flask

• 10 ml pipette

• Burette

Procedure:

1. Pipette 10 ml of bath sample into a 250 ml Erlenmeyer flask.

2. Dilute to approximately 100 ml with deionized water.

3. Add 3-4 drops of methyl orange indicator.

4. Titrate with 1 N acid from yellow to orange/red (pH 4.0).

5. Record the acid consumption (ml).

Calculation:

SurTec® 177 (%) = Acid consumption (ml) × 0.52

Example:

• If acid consumption is 14.0 ml:

• SurTec® 177 = 14.0 × 0.52 = 7.28%

• Result is within operating range (6-8%)

SECTION 20: CRITICAL WARNINGS AND BEST PRACTICES

CRITICAL WARNINGS:

• Causes severe skin burns and eye damage (H314/H318). Highly alkaline. AVOID skin and eye contact.

• May cause respiratory irritation (H335). Avoid inhalation of dust.

• Highly alkaline (pH ~13). Handle with care; Avoid contact with acids.

• Non-combustible. Does not burn.

• Hygroscopic. Absorbs moisture from air. Store in airtight containers.

• Incompatibilities: Keep away from acids, reactive metals (aluminum, zinc), and organic materials.

• Cyanide-free. Safer than cyanide-containing cleaners.

• Non-foaming. Suitable for electrolytic cleaning.

• Hygiene Requirement: Contaminated clothing should not be allowed out of the workplace.

BEST PRACTICE RECOMMENDATIONS:

• Electrolytic Cleaning: Use for iron and steel (cathodic); Use for copper and brass (anodic); Maintain concentration at 60-80 g/l; Current density: 3-8 A/dm²; Temperature: 20-40°C.

• Bath Preparation: Add product slowly to water while stirring; Ensure complete dissolution; Check pH before use.

• Process Control: Perform titration analysis regularly; Maintain concentration in operating range; Monitor temperature and current density.

• Pre-cleaning: For heavy soil, use SurTec 151 before electrolytic cleaning.

• Rinsing: Thorough cold water rinsing after cleaning is essential.

• Maintenance: Filter bath regularly; Top up as needed based on analysis; Replace bath when performance declines.

• Handling: Use in well-ventilated areas; Avoid dust generation; Wear chemical-resistant gloves, protective goggles, face shield, and appropriate respiratory protection.

• Personal Protective Equipment: Wear impermeable gloves (nitrile, neoprene, butyl), chemical safety goggles, full-face shield, protective clothing, and NIOSH-approved dust mask.

• Hygiene: Do not eat, drink, or smoke when using; Wash hands thoroughly after handling; Do not take contaminated working clothes home; Shower at the end of the work shift.

• Storage: Store in tightly closed, properly labeled containers in dry conditions; Keep away from acids and reactive metals; Moisture-proof containers recommended.

• Spill Response: Avoid raising dust; Wear full PPE; Sweep spilled substance into covered containers; Do not allow to enter drains or waterways; Place in properly labeled closed containers.

• Disposal: Dispose of in accordance with local, regional, and national regulations; Do not discharge into sewers or water sources.

TITRATION ANALYSIS REFERENCE:

Quick Reference Formula:

SurTec® 177 (%) = Acid consumption (ml) × 0.52

Example Calculation:

• Acid consumption = 14.0 ml

• SurTec® 177 = 14.0 × 0.52 = 7.28%

• Result: Within operating range (6-8%)

Required Concentration:

• Target: 6-8% (60-80 g/l)

• Top-up: Add product based on titration result
