PEI Spray processing It is a coating method of evenly spraying polyetherimide (PEI) powder on the surface of the coated object. The processing process comprises a plurality of steps: first, the substrate needs to be pretreated, such as cleaning, drying, passivation and phosphating; Then, the ground and filtered PEI powder is evenly sprayed on the surface of the substrate through the electrostatic powder spraying machine; Finally, the PEI powder is cured and attached to the substrate by heat treatment.
PEI spray processing has a variety of advantages, such as improving scratch resistance, aesthetics and texture of coated materials, and has a wide range of applications, mainly involving hardware, plastics, furniture, military, shipbuilding and other fields. In addition, secondary finishing processes such as steam smoothing and flame polishing can further improve the beauty and texture of PEI plastic parts.
What aspects of PEI spray processing are you interested in? For example, its application cases, cost-effectiveness or specific operation steps.
The application effect of PEI spray processing is remarkable, especially in solving the problems of poor adhesion and paint dropping.
In the application of PEI plastic steel spectacle frames, due to the insufficient adhesion between the material itself and the paint, the paint often falls off. The use of PEI plastic steel treatment agent can effectively improve the polarity and wettability of the material surface, enhance the adhesion with the paint, form a solid coating network, and thus solve the problem of paint shedding.
In addition, PEI materials have excellent physical, mechanical, electrical and thermal properties, which enable them to maintain stable performance in high temperature, high frequency and other harsh environments. Therefore, they are widely used in manufacturing optical fiber connectors, high-temperature connectors, electronic industrial coatings and other fields.
In conclusion, the application effect of PEI spray processing not only improves the appearance quality of products, but also further expands the application range of PEI materials.
The selection of a suitable PEI coating processing plant requires comprehensive consideration of several aspects:
Qualification certification and reputation: ensure that the manufacturer has relevant qualification certification, such as ISO9001 quality management system certification, and understand its reputation and reputation in the industry. 1
Technical strength and quality control: The manufacturer should have advanced spraying equipment and technology, provide diversified painting processes, and have a strict quality management system. 1
Cost effectiveness and service level: compare the quotations of different manufacturers, consider their product quality, service level and other factors, and find the partner with the highest cost performance ratio. At the same time, ensure that the factory has a good service attitude and communication ability. 1
Environmental protection awareness: select spraying manufacturers that pay attention to environmental protection, understand their environmental protection policies and practices, and ensure that the production process complies with relevant regulations and standards. 1
To sum up, when selecting PEI coating processing plant, we should fully consider the qualification, technology, quality, cost, service, environmental protection and other factors. 12
