(F) Operation guidance
1. Substrate surface treatment
(1) Degreasing: the oil stain on the
workpiece surface and the gap must be removed.
(2) The substrate needs to be sandblasted
(using about 100 mesh quartz sand), and the surface roughness should reach
40-60 microns.
(3) Use compressed air to blow away sand
and dust on the surface of the substrate. If it is necessary to soak or clean
with solvent, the surface liquid must be air dried or dried.
(4) Put the workpiece into the oven for
preheating, control the temperature at 50~80 ° C, and keep it warm for more
than 30 minutes for spraying.
2. Preparation of painting 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:
(1) Thoroughly clean the equipment with the
thinner matching the original paint to remove the residual paint and residue
inside.
(2) Use special thinner or other soluble
solvent to clean the equipment repeatedly (cleaning for more than 2 cycles).
3. Preparation of paint
(1) Dispersion: Before using the coating,
stir for 5-10 minutes, add appropriate diluent as the case may be, and then
test its viscosity to make the coating liquid disperse evenly.
(2) Filtration: The paint entering the
watering can must be filtered with 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 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.
5. Drying and curing
Keep the temperature at 80 ° C for 20min
and 230 ° 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 the coating, the
container containing the coating shall be covered with a lid and 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 the product at 20-30 ℃ regularly (about 1
month) to prevent sedimentation and condensation.
4. During normal spraying and back
spraying, the surface of the workpiece must be sprayed and wetted without
drying.
(H) Storage conditions
1. Avoid direct sunlight under the
temperature of 5~30 ℃, and the shelf life is 6 months (unopened).
2. Package specification: 1kg, 5kg.
(I) 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 for use when the paint viscosity is adjusted next time.
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 spillage, 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 comes into contact with
skin, please wash it with water and soap. If you feel unwell, seek medical
advice immediately.
4. If you feel uncomfortable after inhaling
spray, immediately transfer to a fresh air place and seek medical advice.
