Chengdu Branch-brand LH-18 type speed wide temperature zinc phosphate solution

(Photo for phosphate coating microstructure micrograph) 1. Overview: This product is under wide temperature range of a zinc phosphate solution widely promoted in the country, can be used within 0 ~ 50 ℃, the deposition rate is very rapid, spray Just 60 ~ 120S (normal 120 ~ 180S), you can soak more than 120S (room temperature 3 ~ 10min). Steel parts after treatment form a uniform, dense, thin phosphate coating, suitable for all types of coating pre-treatment. LH-18 type phosphating agent in the absence of surface adjustment process, but also a complete phosphate film, but the film is more compact table adjusted. 2. Composition: A component: a base liquid, light blue-green liquid; B component: neutralizer, pale white liquid; C components: accelerator, pale yellow liquid. 3. Usage: Project usage total acidity (point) 18 to 35 free acidity (point) Baptist: 0.7 to 1.5 Spray: 0.5 to 1.2 Promote the concentration (dot) 2-3 (with higher concentrations in winter) temperature treatment (℃) 0 ~ 20 20 ~ 30 30 ~ 50 Processing time (min) 10 2.5 1.5 coating weight (gm2) 1 ~ 2 film thickness (μm) 1.5 ~ 4 4. Use process: degreasing, rust → water Cleaning phosphate → water washing → drying (preferably dry), rust → water washing → conditioning → phosphating → water washing → drying (preferably dry) 5. Package and transportation of this product 25 points, 30kg plastic pail, shelf life of one year.
