6. Operation instructions

6.1. Surface treatment of base material

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

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

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

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

6.2. Preparation of spraying equipment

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

6.2.1. Thoroughly clean the equipment with diluent matching with the original paint to remove the residual paint and residue inside.

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

6.3. Preparation of coating

6.3.1. Dispersion: shake or stir the coating for 5-10 minutes before use, depending on the actual situation

Whether it is necessary to add diluent, and then test its viscosity and make the coating liquid disperse evenly.

6.3.2. Filtration: The paint entering the spray can must be filtered with a 100 # filter screen to remove the solids that may be mixed in, so as to avoid blocking the gun or forming particles on the surface of the workpiece.

6.3.3. The coating shall be adjusted when used. The prepared coating shall be used up at one time during construction.

6.4. Paint spraying: select a spray gun with nozzle diameter of 0.5~1mm, spray pressure of 2~0.3MPa (2~3kgf/cm2), and control the distance between the nozzle and the base material to keep between 15~30cm during spraying.

6.5. Drying and curing

The first method: stand for 72 hours after spraying;

The second method: keep the temperature at 80 ° C for 30min after spraying. 6. About polishing

If the surface needs to be polished, the surface can be rubbed repeatedly with a soft satin cloth to remove the floating molybdenum disulfide powder. If a shiny surface is not required, keep the matte surface

It is more appropriate to use.

7. Precautions

1. The workplace must be well ventilated.

2. During the use of the coating, the container containing the coating shall be covered with a lid, sealed for use and storage.

3. This product may be unstable when the temperature changes. Please store the product at 5-30 ℃ and gently stir or shake it regularly (about 1 month) at 20-30 ℃ to prevent sedimentation and condensation.

8. Storage conditions

1. Keep away from direct sunlight at a temperature of 5~30 ℃, and keep it for 6 months (unopened).

2. Package specification: 1kg, 5kg.

9. Waste discharge

1. It is recommended to clean the spray gun, spray irrigation and equipment with diluent. The diluent after washing can be filtered and stored for use when the viscosity of the coating is adjusted next time.

2. Do not discharge the paint and its cleaning residue into the waste water system, but put it into a specific container for storage, and conduct professional treatment according to local and national environmental protection laws and regulations.

10. Emergency treatment

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

2. If this product enters the eyes accidentally, immediately flush it with plenty of water for at least 15 minutes. If you feel pain, please see a doctor immediately.

3. If this product comes into contact with skin, please wash it with water and soap, and seek medical advice immediately if you feel unwell.

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