Product description

| Category | Details |
|---|---|
| Product Overview | LG303 is a high-performance, low-foam, weakly alkaline degreaser specially designed for ultrasonic cleaning equipment. It combines the synergistic advantages of chemical cleaning and ultrasonic cavitation effect, with formula optimized for ultrasonic field characteristics. It generates fine and stable cavitation bubbles, efficiently removes stubborn release agent, cutting fluid, polishing paste and dust from blind holes, threads, narrow gaps and complex surfaces of die-cast aluminum parts, ideal for cleaning precision die-castings. |
| Chemical Properties | Property: Weakly alkalineAppearance: Colorless to pale white transparent liquidCorrosivity: Slightly corrosive |
| Product Features | 1. Excellent ultrasonic synergistic effect: Reduces cavitation threshold, generates more uniform micro cavitation bubbles, enhances physical cleaning force of cavitation erosion and micro jet2. Good cavitation transmission: Optimized solution viscosity and surface tension, high ultrasonic energy transmission efficiency, low attenuation, uniform cleaning3. Strong chemical cleaning: Excellent emulsification and dispersion ability for silicone and wax-based release agents, chemical + physical synergy achieves 1+1>2 cleaning effect4. Excellent aluminum protection: Multiple corrosion inhibitors, continuously protect aluminum alloy in ultrasonic cavitation environment, prevent pitting, luster loss and hydrogen embrittlement5. Low foam & long life: Strict low foam control, avoid sound energy absorption by foam; strong anti-fouling ability, long service life6. Eco-friendly & safe: Free of phosphorus, nitrite and heavy metals, environment-friendly and safe to operate |
| Process Parameters | Alkalinity index: 5-15Temperature: Room temperature - 60°C (optimal 50°C±5°C)Treatment time: 3-5 minutesRecommended ultrasonic frequency: 28kHz, 40kHz, 80kHz (wide frequency adaptation)Surface tension (25°C, 10% solution): ≤35 dyn/cmTank preparation: 10-20%, dilute with water to 1 ton |
| Application Scope | Materials: Die-cast aluminum alloy, wrought aluminum alloy, precision aluminum alloy partsContaminants: Stubborn die-casting release agent, precision processing oil, polishing residue, fingerprints, micro particlesWorkpieces: Precision die-castings with deep blind holes, complex cavities, fine threads, dense tooth grooves, cross holesIndustries: Automotive engine parts, fuel system parts, hydraulic components, electronic communication structural parts, high-end consumer hardwarePost-process: Ultimate cleaning before electroplating, anodizing, PVD coating, vacuum brazing, precision assembly, surface inspection |
| Standard Process Flow | Loading → Ultrasonic Degreasing → Multi-stage Rinsing → Drying |
| Operation Method | Preparation: Add 80% water (deionized water recommended), add LG303, stir and heat; monitor concentration dailyLoading: Place workpieces in special cleaning basket reasonably, avoid overlapping, sticking to bottom/wall, prevent sound shadow area; fix precision workpieces with fixturesCleaning: Fully immerse workpieces, start ultrasonic, cooperate with slow swing/lifting mechanism to improve uniformityRinsing: 1st optional ultrasonic hot water rinsing, 2nd normal temperature spraying/immersion rinsing, 3rd deionized water fine rinsingDrying: Dry immediately by hot air circulation drying, vacuum drying or centrifugal dehydration + air blowing |
| Bath Maintenance | Monitor concentration daily with refractometer or alkalinity titration, replenish in time; filter bath regularly with ≤25μm precision filter to remove solid particles; replace when bath is turbid, black or cleaning force decreases |
| Precautions | Protection: Wear alkali-resistant gloves and safety gogglesEquipment matching: Ensure ultrasonic power and transducer layout match tank volume; regularly check vibrator plate cleanliness, prevent scale from affecting efficiencyProcess control: Strictly control temperature; never start ultrasonic with no load or insufficient liquid level; process verification required for high silicon aluminum alloyWastewater treatment: Collect waste liquid, neutralize and discharge after reaching standard |
| Storage & Packaging | Packaging: 25kg/plastic drum, 1000kg/plastic drumStorage: Cool and ventilated place, avoid direct sunlight and freezingShelf life: 24 months unopened |
