Note:
1. All data in sheet 1 and sheet 2 are based on laboratory tests and practical experience.
2. It is recommended that the product should pass the process evaluation before batch use to avoid unnecessary losses to customers due to various reasons such as process.
◎Pipe Film Operation Process
1) Remove oil, rust and other loose deposits, moisture, etc. on the surface.
2) Sand blasting or shot blasting to Sa2.5 level, anchor pattern depth 60 ⁓100μm, dust removal on the surface to near white level, pay attention to adding new and old sand evenly to make the ratio stable.
3) Thoroughly clean the surface of the pipe.
4) Special primer is required for spraying, and the spraying thickness should be below 25μm. Note that the thickness of the primer should not overwhelm the depth of the anchor pattern.
5) Preheating, put the pipes sprayed with primer into the heating furnace for preheating, generally controlled at 175 ⁓190℃.
6) Coat the powder coating on the inner surface of the pipe with a thickness of more than 200μm.
7) Put the coated pipe into the heating furnace and cure at 200±10℃ for 80±5min to make the coating reach the best state.
8) Test the coating performance after the coating is naturally cooled.
◎Storage
1. The product should be stored in a cool, ventilated, dry room with a temperature below 25°C and a humidity below 60%.
2. Keep away from fire and heat insulation.
3. The package can be opened at any time, and it should be sealed in time after use to prevent the powder from being polluted and damp.
4. Minimize the number of movements and avoid impact and pressure.
5. The stable storage period is 12 months.
Note: Improper storage conditions can easily cause the epoxy powder product to deteriorate, agglomerate and become unusable.
◎Package and Transportation
This product is a non-hazardous item. Packed in carton, 25kg per carton, the carton is lined with polyethylene plastic bag. During the shipping process, it should be lightly loaded, lightly unloaded and protected from direct sunlight, heat and moisture.
