Notes on Application of the Products
1. Coating Process The metal articles to be coated are passed the fore-treatment of oil and rust removal, phosphorization, cleaning and drying, and then spraying and solidification, the complete elaborate coated products are obtained. The flow sheet is as follows: Working articles¡úRemoval of oil and rust¡úPhosporization¡ú Cleaning and drying ¡úElectrostatic spraying¡úSolidification¡ú Cooling¡úProduct quality inspection¡úPackaging¡úPutting in storage 2. Notes for working Compressed air used for coating must be free from oil, water or other impurities by a separator to avoid the appearance of needle holes or contraction holes Electrostatic pressure : 50-100KV Gap between the sprayer and the article: 200-300 mm Spraying air pressure: 1-2Kg/cm2 Temperature of the drier should be uniform within a scope of ¡À5¡æ 3. Package: 40 Kg per paper barrel with lining bag of PE 4. Storage: Stored in dry, ventilated and low temp. rooms, far from fire and heat sources. To avoid sunshine exposure and rain in transportation. The powder coating container after opened should be carefully sealed up to prevent moisture and avoid the degradation of the powder. |
The
various powder coatings produced by our factory are applied by high-pressure
electrostatic coating method. The coating film obtained is good in characteristics
and the utilization of powder is high. They are welcome deeply by the
