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. The base material needs to be sandblasted (using about 100 mesh quartz sand), and the surface roughness should reach about 20 microns.

6.1.3. Blow the sand and dust on the substrate surface with compressed air. If solvent immersion or cleaning is required, the surface liquid must be dried or dried.

6.1.4. Put the workpiece into the oven for preheating, control the temperature at 80~100 ° C, and keep it warm for more than 20 minutes (depending on the material, shape and size of the workpiece, the indicators are different, which can be determined by the field test) for spraying.

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 paint 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: Before using the coating, mix for 5-10 minutes, add an appropriate amount of diluent according to the actual situation, and then measure 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. Painting

Select a spray gun with a nozzle diameter of 1.0~1.5mm and a spraying pressure of 2~0.3MPa (2~3kgf/cm2). During spraying, control the distance between the nozzle and the base material to keep between 15~30cm.

6.5. Drying and curing

Heat preservation at 80~100 ° C for 20 minutes, and heat preservation at 230 ° C for 30 minutes.

6.6. Cooling mode

After the workpiece film is solidified, it can be cooled by furnace cooling or air cooling. Please note that the uncooled film is in a soft film state, which is not easy to touch and collide, and does not have the properties described.

7. Precautions

7.1. The workplace must be well ventilated.

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

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

And the product shall be gently stirred or shaken regularly (about 1 month) at 20-30 ℃ 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. Keep away from direct sunlight at a temperature of 5~30 ℃, and keep it for 12 months (unopened).

8.2. Package specification: 1kg, 5kg.

9. Waste discharge

9.1. 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.

9.2. Do not discharge the paint and its cleaning residue into the waste water system, but put it into a special container for storage, 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 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.

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

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