(F) . Operation instructions
1. Surface treatment of base material
1.1. Degreasing: the oil stain on the workpiece surface and the gap must be removed.
1.2. The substrate needs to be sandblasted (using about 100 mesh quartz sand), and the surface roughness should reach 40-60 microns.
1.3. Blow the sand and dust on the surface of the substrate with compressed air. If it is necessary to soak or clean with solvent, the surface liquid must be air dried or dried.
1.4. Place the workpiece in the oven for preheating, control the temperature at 80 ° C, and keep it warm for more than 30 minutes for spraying.
2. Preparation of spraying equipment
Before using the spraying equipment, it is necessary to thoroughly clean the relevant equipment, such as the spray gun, spray pot or paint pot. The recommended cleaning process is as follows:
2.1. Thoroughly clean the equipment with thinner matching the original paint to remove the residual paint and residue inside.
2.2. Use special thinner or other soluble solvent to clean the equipment repeatedly (cleaning for more than 2 cycles).
3. Preparation of coating
3.1 Dispersion: Before using the coating, stir for 5-10 minutes, add appropriate amount of thinner according to the actual situation, and then test its viscosity to make the coating liquid disperse evenly.
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 to avoid blocking the gun or forming particles on the surface of the workpiece.
(3) The paint shall be adjusted when it is used. The prepared paint shall be used up at one time during construction.
4. Painting
The spray gun with a nozzle diameter of 1.0~1.5mm shall be selected, and the spraying pressure shall be 2~0.3MPa (2~3kgf/cm2). During spraying, the distance between the nozzle and the substrate shall be kept between 15~30cm.
5. Drying and curing
Keep the temperature at 80 ° C for 20min, and keep the temperature at 200 ° C for 30min.
6. Cooling mode
After the film of the workpiece is solidified, it can be cooled by furnace cooling or air cooling. Please note that the uncooled film is in a soft film state, not easy to touch and collide, and does not have the said properties.
(G) . Precautions
1. The workplace must be well ventilated.
2. During the use of paint, the container containing paint shall be covered with a lid and sealed for use and storage.
3. The product may be unstable when the temperature changes. Please store the product at 5-30 ℃, and gently stir or shake the product at 20-30 ℃ regularly (about 1 month) to prevent sedimentation and condensation.
4. During normal spraying and back spraying, the workpiece surface must be sprayed and wetted to prevent dryness.
(H) . Storage conditions
1. Avoid direct sunlight when the temperature is 5~30 ℃, and the shelf life is 12 months (unopened).
2. Package specification: 1kg, 5kg, 20kg.
(1) . Waste discharge
1. It is recommended to use thinner to clean the spray gun, spray irrigation and equipment. The washed thinner can be filtered and stored until the next time when the paint viscosity is adjusted.
2. Do not discharge the paint and its cleaning residue into the waste water system, but store it in a specific container and treat it professionally according to local and national environmental protection laws and regulations.
(J) . Emergency treatment
1. In case of leakage or overflow, please wash it with plenty of water.
2. If the product accidentally gets into the eyes, immediately rinse with plenty of water for at least 15 minutes. Seek medical attention immediately if you feel pain.
3. If this product contacts the 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.
