(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 40~60 ° C, and keep it warm for more than 20 minutes for
spraying.
2. Spraying equipment Before using the spraying equipment, it is
necessary to thoroughly clean relevant equipment, such as spray guns, spray
pots or paint cans. 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. The spray gun with a nozzle diameter of 1.0~1.5mm is selected for
coating spraying. 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 Dry and cure at room temperature for 96 hours or
heat preservation at 30~60 ° C for 20 minutes, and heat preservation at 80 ° C
for 30 minutes.
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.
