6. Operation guidance

6.1. Surface treatment of base material

6.1.1. Degreasing: the oil stain on the workpiece surface and the gap must be removed.

6.1.2. Dust removal: the dust on the workpiece surface must be removed.

6.1.3. Water removal: the water on the workpiece surface must be removed.

6.1.4 The workpiece can also be put into the oven for water removal, and the temperature shall be controlled at 80 ° C for more than 30 minutes.

6.2. Spraying equipment Before using the spraying equipment, it is necessary to thoroughly clean the relevant equipment, such as the spray gun, spray pot or storage tank. The recommended cleaning process is as follows:

6.2.1. Clean the equipment thoroughly with diluent matching the original paint to remove the residual paint and residue.

6.2.2. Use special thinner or other soluble solvent to clean the equipment repeatedly (cleaning for more than 2 cycles).

6.3. Preparation of paint

6.3.1. Dispersion: Shake or stir the coating for 5-10 minutes before use, and decide whether to add thinner according to the actual situation, then test its viscosity and make the coating liquid disperse evenly.

6.3.2. Filtration: The paint entering the watering can must be filtered with a 100 # filter screen to remove the solids that may be mixed in, so as not to cause gun plugging or the formation of particles on the surface of the workpiece.

6.3.3. The paint shall be adjusted when it is used. The prepared paint shall be used up at one time during construction.

6.4. Painting

The spray gun with a nozzle diameter of 0.5~1mm is selected, and the spraying pressure is 2~0.3MPa (2~3kgf/cm2). During spraying, the distance between the nozzle and the substrate is controlled to be 15~30cm.

6.5. Drying and curing

The first method: leave it for 72 hours after spraying;

The second method: heat preservation at 80 ° C for 30min after spraying.

6.6. About polishing

If a bright surface is required, the surface can be repeatedly lightly wiped with a soft satin cloth to remove the floating molybdenum disulfide powder. If a bright surface is not required, it is more appropriate to keep the matte surface.

7. Precautions

7.1 The workplace must be well ventilated.

7.2 During the use of the paint, the container containing the paint shall be covered, sealed, used and stored.

7.3 The product may be unstable when the temperature changes. Please store at 5-30 ℃,

And gently stir or shake the product at 20-30 ℃ regularly (about 1 month) to prevent sedimentation and condensation.

7.4 During normal spraying and back spraying, the surface of the workpiece must be sprayed and wetted without drying.

8. Storage conditions

8.1. Avoid direct sunlight when the temperature is 5~30 ℃, and the shelf life is 12 months (unopened).

8.2. Package specification: 1kg, 5kg.

9. Waste discharge

9.1. It is recommended to use thinner to clean the spray gun, spray irrigation and equipment. The washed thinner can be filtered and stored for use when the paint viscosity is adjusted next time.

9.2. Do not discharge the coating and its cleaning residue into the waste water system, but store it in a specific container, and conduct professional treatment according to local and national environmental protection laws and regulations.

10. Emergency treatment

10.1. In case of leakage or overflow, please wash it with plenty of water.

10.2. If the product accidentally gets into the eyes, immediately wash it with plenty of water for at least 15 minutes. Seek medical attention immediately if you feel pain.

10.3. If the product contacts the skin, please wash it with water and soap, and seek medical advice immediately if you feel unwell.

10.4. If you feel uncomfortable after inhaling spray, immediately transfer to a place with fresh air and seek medical advice.
