What I recommend today is a popular introduction to water-based industrial coatings. Our common coatings may be wall decoration building materials that are applied to the walls during decoration operations, but today we recommend them to you. Water-based industrial coatings are mainly used in production and processing. They do not produce environmental pollution and are a new type of green and environmentally friendly coatings. The products are made of water-based resin pigments and various deionized water. They also have excellent anti-rust and anti-corrosion properties. You can refer to the following to learn more.
1. Water-based industrial coating dipping construction technology
1. Add a measured amount of environmentally friendly industrial coating to a clean and dry special dipping tank, start the circulation pump, and slowly add Pure water (thinner) 5~20 (according to the specific requirements of paint film thickness and working temperature), after it is fully uniform, mature for 1~2 days (subject to the complete disappearance of foam during the cycle).
2. Before the workpiece enters the paint dipping tank, if there is local water accumulation, compressed air should be used to dry it. Particular focus should be placed on workpiece gaps.
3. Usage:
Start the circulation pump, the temperature is best controlled at 25°C, and the construction viscosity is controlled at 20 to 30 seconds. It takes about 2 minutes.
After coming out of the tank, drain it vertically for 20 to 30 minutes, then send it to the drying room, heat it to 70±5℃ and keep it for 15min, then raise the temperature to 120℃ and keep it for 20~30min before releasing it from the oven.
There are no appearance problems, and the physical properties of the paint film can be tested after 48 hours.
4. Maintenance:
Keep the tank fluid clean and minimize and eliminate the introduction of contaminants.
When heating, the circulation pump must be started to avoid local overheating. The temperature of the paint tank must not exceed 40°C.
If it is left unused for a long time, start the circulation pump for 1 to 2 hours every 3 days to maintain its activity.
The pH value of the bath liquid should be controlled at 8.0~8.5.
5. To ensure that the surface of the workpiece is clean, it is recommended to clean the groove every 6 months.
6. If the heating device does not work properly, adjust the working viscosity of the dipping paint when it is lower than 20°C
2. Notes on the use of water-based industrial coatings
Store in a cool, dry and ventilated place, avoid frost.
The storage period is 12 months. After the storage period, it can still be used if it meets the requirements according to standard testing.
During storage and transportation, collision, sun and rain should be avoided.
1. This product cannot be mixed with other oil-based paints or other water-based paints.
2. When the storage time is too long, stratification may occur. At this time, add an appropriate amount of neutralizer to make the pH value of the paint reach 9.0 to 10.0, and it can continue to be used.
3. When using, stir thoroughly and filter, and use clean water as diluent.
4. Construction is not suitable when the construction environment temperature is lower than 5℃ or the humidity is higher than 85℃.
The water-based resin paint recommended above is a new type of paint product. On the one hand, from the perspective of raw materials, they are made of water-based resin pigments and various deionized water. , is an environmentally friendly coating. On the other hand, the product has excellent rust removal and anti-corrosion properties, and is especially suitable for the surface protection of exported steel. You can use this as a standard to choose a suitable and reliable one. Water-based industrial coatings, I believe this will achieve a satisfactory final effect.
