Ceramic coating

　　Ceramic coating operation instructions

　　Type : single layer and multiple layers (primer, topcoat, spot)

　　Color : multiple colors

　　Operating procedures:

　　4. Substrate processing

　　1) Degreasing

　　Thoroughly remove the grease from the substrate with alkali or acid, then rinse the acid or alkali on the substrate with water.

　　2) Sanding : Number of sands : 60-80 mesh. Sandblasting roughness: 8-12 microns

　　3) Dust removal : Clean the dust on the substrate with clean water.

　　5. Paint ripening method

　　1) Prepare the paint

　　Stir the solution A thoroughly (usually with a roll method and stir at 150 rpm for more than 30 minutes until the precipitate is completely removed).

　　2) Paint mixing

　　Pour liquid B into solution A and shake immediately for more than 20 seconds. P liquid is then poured into the mixed components of A and B.

　　3) Rolling and aging method , rolling speed: 80~100 rpm.

　　4) Ripening time : 8~12 hours

　　5) Mature environment : the ambient temperature is around 25 degrees.

　　6) After the ripening is completed, it must be used within 24 hours at room temperature, otherwise it should be refrigerated (5°C - 10°C)

　　7) Use after filtering 300 mesh filter ( if you need to add glitter in the topcoat, please filter the cooked topcoat and then add the flash powder. The added amount can be adjusted by the customer )

　　8) Storage time of cooked paint

　　Refrigerated at 5~10 degrees, can be kept for 3 days

　　6. Spraying

　　1) Preparing cooked paint

　　In order to use the refrigerated storage material, the paint should be uniformly mixed, the paint should be shaken for more than 30 minutes, the paint temperature should be adjusted to normal temperature, and filtered with a 300 mesh filter before use.

　　2) Spraying process

　　‚ Preheating: preheating surface temperature is 50~80 degrees

　　Spraying method: air spray gun spraying

　　ƒ Spray thickness: single layer: 35 ± 7 microns.

　　Double layer: primer 25 ± 5 microns, topcoat: 10 ± 2 microns. Primer and topcoat spray ratio 2.5~3:1 (weight ratio).

　　3) Ethanol or IPA when washing the spray equipment

　　7. Curing

　　1) Baking conditions

　　290~310°C (MPT standard)×10 minutes

　　2) Curing engineering drawings (temperature and time)

Time (minutes) temperature (degrees Celsius)

　　(The surface temperature of the factor is different from the temperature of the air in the oven, so it is necessary to measure the surface temperature of the material frequently)
