Ce este acoperirea cu pulbere?
O metodă de acoperire cu pulbere realizată din rășină epoxidică termorezistentă, rășină poliesterică de reticulare sau rășină acrilică, etc. pe tesaturi, fire, tuburi si sticle.
Pulberea poate fi aplicată pentru a forma un strat, o cusătură, sau un design gravat. Pentru acoperiri termoplastice, stratul de pulbere este încălzit pentru a se lega de materialul fibros.
Advantages of powder coat aluminum sheet.
- Strong compactness, uniform thickness of paint film, no leakage of paint.
- Existing in powder state, there is no "three wastes" in the manufacturing process, and there is no need to add solvents during the use process. Air is used as the dispersion medium, and high-voltage electrostatic adsorption is used for painting.
- Powder coating is an environment-friendly product with four major features: Efficiency, Economy, Ecology, and Energy. It is called "4E" paint internationally.
- Powder coating process is simple, fara poluare, no loss, good coating surface, rezistență puternică la coroziune, etc.
Powder spraying diamond plate process.
Powder spraying process is also known as electrostatic spraying. The basic process of powder spraying process is as follows:
1, the previous; 2. Pretratament; 3. Pretreatment water drying; 4. Electrostatic spraying; 5. The curing; 6. Next thing.
The working principle of powder spraying process is not atomization, but electrostatic field adsorption. Powder is sprayed on the workpiece under the action of electrostatic attraction and air flow, and is heated and solidified into film.
În primul rând, the preliminary treatment of pre-spraying workpiece is to remove grease, dust and other dirt on the surface of the workpiece, to ensure good adhesion of the subsequent coating, and improve the comprehensive performance and quality of the layer. Commonly used pretreatment methods are: wipe phosphating solution, spray, shot blasting, sablare, măcinare, liquid tank immersion, etc.
The pretreated workpiece is ready for powder spraying.
After spraying, the workpiece enters the high temperature curing furnace to melt powder → leveling → constant temperature curing → when the next part is out of the oven, the next part should pay attention to reduce scratches. Finish coating process for workpiece.
Processing process of embossed aluminum plate (Placă de rulare din aluminiu)
- Ingrediente: calculate the amount of ingredients added to each alloy according to the specific manufacturing alloy number, and then match reasonable raw materials.
- Topirea: according to the requirements of manufacturing, the supporting raw materials are put into the smelting furnace for smelting, and then the miscellaneous slag and gas are treated by degassing and slag removal.
- Casting: În condiții de turnare adecvate, molten aluminum refined in the Deep well casting system is cooled and cast into round casting rods of various specifications.
- extrudare: Extrusion of a heated round cast rod in a mold. In the extrusion process, air cooling quenching process and manual aging process should be used to complete the heat treatment. Different models have different heat treatment intensities.
- Colorare: Acesta este ultimul pas. Aluminum profiles must be oxidized before coloring. În general, the corrosion resistance of oxidized alloy profiles is relatively weak, so it must be anodized to achieve the desired effect.
