(F) Operation guidance
1. Substrate surface treatment
(1) Degreasing: the oil stain on the workpiece surface and the gap must be removed.
(2) After the nitriding treatment of the substrate, the surface residue shall be removed and cleaned to keep it dry.
(3) Do not touch the pin surface with your fingers. Wear hairless gloves to hold the pin. If there is oil stain on the surface, soak or clean it with solvent.
(4) Put the workpiece into the oven or drying tunnel for preheating, control the temperature at 40~60 ¡ã C (adjust according to the ambient temperature), 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 the relevant equipment, such as the spray gun, spray pot or material storage tank. The recommended cleaning process is as follows:
(1) Clean the equipment thoroughly with special thinner to remove the residual paint and residue.
(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. It is recommended to paint more than twice, and the thickness should be controlled within 20~30 ¦Ì m. The surface shall be sprayed evenly without sagging.
5. Drying and curing
Dry and cure at room temperature for 96 hours or heat preservation at 30~60 ¡ã C for 20 minutes, and heat preservation at 120 ¡ã 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 ¡æ, and gently stir or shake the product at 20-30 ¡æ 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. Keep away from direct sunlight at a temperature of 25 ¡æ for 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.
