One Side Corona Pet Film for FRP Sheet

Fiberglass reinforced plastic sheets are a composite material with broad application prospects, and their unique properties and plasticity have attracted attention in fields such as construction, transportation, and chemical engineering. However, surface treatment is a crucial step in the manufacturing process of fiberglass sheets. In order to improve the surface energy of fiberglass sheets and ensure their perfect adhesion to the film, researchers have been seeking more effective methods. In recent years, a material called single-sided corona Pet thin film has gradually attracted attention, playing an important role in the surface treatment of fiberglass sheets.
Single sided corona Pet film, as the name suggests, refers to polyester film with only one side treated with corona. The characteristic of this thin film is that the corona treated side has extremely high surface energy, while the untreated side has lower surface energy. By utilizing this difference, single-sided corona Pet film can achieve directional adhesion on the surface of fiberglass sheets, thereby improving the adhesion effect.
The application of single sided corona Pet film in the manufacturing of fiberglass sheets mainly involves the following steps:
Clean the surface of fiberglass sheets to ensure their cleanliness and smoothness. This is the fundamental work for achieving perfect adhesion and must be given sufficient attention.
Apply adhesive evenly on the surface of fiberglass sheets to ensure appropriate coating thickness. It should be noted that suitable adhesives should be selected based on different types and uses of fiberglass sheets.
Attach the untreated side of the single sided corona Pet film to the surface of the fiberglass sheet to ensure close contact between the two. After this step is completed, the adhesive will gradually penetrate between the two, forming a tight adhesive layer.
Perform hot pressing treatment on the bonded material at a certain temperature and pressure to achieve chemical bonding between single-sided corona Pet film and fiberglass sheet material. The temperature and time of hot pressing treatment should be adjusted according to specific material characteristics and process requirements.
After the above steps, the single sided corona Pet film and fiberglass sheet have achieved perfect adhesion. This new surface treatment method not only improves the adhesion performance of fiberglass sheets, but also provides possibilities for their application in more fields.
The application value of single sided corona Pet film is mainly reflected in the following aspects:
Improve the bonding effect of fiberglass sheets. The directional bonding effect of single sided corona Pet film on the surface of fiberglass sheets significantly improves the bonding effect, providing better performance guarantee for the manufacturing and use of fiberglass products.
Expand the application range of fiberglass sheets. By using single sided corona Pet film for surface treatment, fiberglass sheets can be widely used in fields such as construction, transportation, chemical engineering, aerospace, etc., fully leveraging their unique performance advantages.
Reduce production costs. The use of single sided corona Pet film for surface treatment can reduce post processing steps, thereby reducing production costs and improving production efficiency.
Improve product quality. The application of single sided corona Pet film can reduce the detachment phenomenon of fiberglass sheets during use, improve the durability and stability of products, and thus improve product quality.
In summary, the application of single sided corona Pet film in the surface treatment of fiberglass sheets has achieved perfect adhesion, improved product quality and production efficiency, reduced production costs, and provided possibilities for the application of fiberglass sheets in more fields. With the continuous development of technology, there are many possible improvements and extensions for single sided corona Pet films in the future, which will bring more possibilities for the manufacturing and application of fiberglass sheets
