| Item | Details |
|---|---|
| Product Overview | An innovative eco-friendly treatment agent specially designed for automatic spray production lines. This product must be used with the special LG707 2-in-1 Additive to simultaneously complete powerful degreasing, oxidation removal and protective conversion film formation for steel and aluminum in a single spray station. Based on eco-friendly surfactants, complexing agents and chelating agents, it achieves extremely simplified process flow with strong cleaning power, fast treatment speed, environmental protection and long bath life, making it an ideal choice for upgrading pretreatment in modern high-efficiency production lines. |
| Main Specifications | Appearance: Pale blue liquidpH=1–2 |
| Core Advantages & Features | 1. High-efficiency integration for spray process: Specially designed for spraying, completes degreasing, derusting/oxidation removal and film formation in one stop within 2–4 minutes of short spraying, greatly improving production line beat and space utilization.2. Excellent cleaning and film-forming performance:Fast and strong cleaning: Optimized low-foam surfactant system suitable for spraying, quickly stripping stamping oil, cutting fluid, anti-rust oil, etc.Synchronous oxidation removal: Removes floating rust on steel and aluminum oxide film while cleaning through chelation to activate the surface.Instant protective film: Forms uniform conversion film on clean metal surface immediately, providing good adhesion base and short-term rust protection for subsequent processes.3. Outstanding production and economy:Room temperature operation, remarkable energy saving: No heating needed, directly reducing energy cost.Long service life, simple management: Stable bath, strong anti-interference ability, low maintenance frequency, excellent comprehensive cost.Simplified process, investment saving: Combines multiple traditional processes, reducing equipment investment and floor space.4. Environmental protection and material versatility:Eco-friendly formula: Free of controlled substances such as chromium, nickel, nitrite, low wastewater treatment burden.Multi-material universal: Suitable for mixed production of steel and aluminum, especially for scenes with multi-material workpieces such as auto parts, chassis and cabinets. |
| Process Parameters | Temperature: Room temperatureEffective spray time: 2–4 minutesBath preparation ratio: 2.5% 2-in-1 conversion coating agent + 2.5% 2-in-1 additive |
| Application Scope | Applicable materials: Steel and aluminum, suitable for mixed or separate treatment.Applicable contaminants: Light to medium oil (stamping oil, cutting fluid, anti-rust oil), floating rust, heat treatment oxide color, natural aluminum oxide film.Applicable process: Automatic spray production line.Application scenarios: Modern factories with high requirements for production beat, space utilization and environmental protection.Subsequent processes: Short-term rust prevention layer or pretreatment for coating (electrophoresis, powder coating, painting). |
| Standard Process Flow | Bath preparation → Spray treatment → Water rinsing → Post-treatment/drying1. Bath preparation: Add ~80% water to spray tank. Under circulation stirring, add 2.5% LG407 first, then 2.5% LG707. Add water to working level, start circulation pump and spray system, mix thoroughly. Confirm working solution pH within 2.5–5.2. Spray treatment: Set spray time 2–4 minutes, adjust pressure for full coverage. Workpiece is fully sprayed to emulsify oil, dissolve oxide layer and form film synchronously.3. Post-treatment: Rinse thoroughly with running water immediately (two-stage recommended). Neutralization and sealing treatment (passivator or dehydrating anti-rust agent) is recommended. Dry timely. |
| Bath Management & Maintenance | 1. Key monitoring: Check pH daily with precision pH meter, strictly control at 2.5–5. pH is critical for balancing three functions.2. Maintenance & replenishment: pH rises during operation. When pH > 5.0, replenish at volume ratio LG407:LG707 = 1:2. Mix or add to auxiliary tank first, then fully mix into main tank via circulation pump.3. Bath renewal: Replace completely if bath is heavily dirty, excessive foaming or treatment effect cannot be restored after replenishment.4. Equipment maintenance: Clean nozzles and filters regularly to prevent clogging. |
| Precautions & Safety | 1. Personal protection: Working solution is strongly acidic. Must wear acid-resistant gloves, goggles and acid-proof clothing during maintenance and replenishment.2. Process limitations: Mainly for light to medium contamination. Pre-treatment required for heavy solid oil, dense oxide scale or severe rust. The formed film is mainly for adhesion enhancement and short-term rust prevention; special passivation or coating recommended for long-term corrosion resistance.3. Foam control: Strictly monitor foam in spray process. Use compatible defoamer if foam increases due to abnormal water quality or oil contamination.4. Wastewater treatment: Waste liquid is acidic with metal ions, must be neutralized and precipitated before discharge. |
| Packaging & Storage | Packaging: 25kg/plastic drum, 1000kg/plastic drumStorage: Store separately in cool and ventilated area, avoid direct sunlight and high temperature. Keep sealed.Shelf life: 12 months (original sealed package) |
