1. Background
Epoxy slurry is a high-performance composite material with excellent mechanical properties, chemical stability and corrosion resistance, which is widely used in aerospace, automobile manufacturing, electronic products and other fields. In the preparation process of epoxy slurry, it is necessary to mix epoxy resin, hardener, filler and other raw materials evenly according to a certain formula ratio, and then evenly coat the mixed slurry on the substrate through a film scraping machine, and finally form a coating or composite material with specific properties.
2. Principle and process of film scraping machine
A film scraper is a device used to evenly coat liquid or semi-solid materials on flat or curved surfaces. The principle is to evenly scrape the slurry on the surface of the substrate through a scraper, and then form a coating through a drying or curing process. The process flow of the film scraper mainly includes the steps of slurry preparation, scraping parameter setting, scraping process control, and drying or curing treatment.
3. Advantages and problems of film scraper in epoxy slurry preparation
The film scraper has the advantages of easy operation, high production efficiency and controllable coating thickness in the preparation of epoxy slurry, which can meet the slurry coating needs of different viscosities and different surface requirements. However, some problems will also be encountered in practical applications, such as uneven scraping, air bubbles, inconsistent coating thickness, etc. In view of these problems, they can be solved by adjusting the angle of the scraper, controlling the scraping speed, and optimizing the slurry formula.
4. Technology selection and optimization
When choosing a film scraper, it is necessary to consider the viscosity of the slurry, the coating area, the coating thickness and other factors. For high-viscosity epoxy slurry, the coating roller can be used to assist the film scraper to improve the coating efficiency; For large-area coating needs, a wide web scraper can be used to improve production efficiency. In addition, optimizing the operating parameters and process flow of the scraper can also improve the coating quality and production efficiency.
5. Application prospects
The application of film wiper technology in the preparation of epoxy slurry has broad prospects. With the wide application of epoxy slurry in aerospace, automobile manufacturing and other fields, the requirements for film scrapers are getting higher and higher. In the future, the film scraping machine will be more intelligent and accurate, providing better technical support and guarantee for the preparation of epoxy slurry.
conclusion
The application selection and optimization of the film scraper in the preparation of epoxy slurry is of great significance for improving the coating quality and production efficiency of epoxy slurry. By reasonably selecting the type of film scraper and optimizing the process, the efficient and accurate coating of epoxy slurry can be realized, and the application and development of epoxy slurry in various fields can be promoted.
