PET rilis film produksi proses
Apr 30, 2024
PET release film, as the name suggests, is a polyester film with specific release properties on the surface. This type of material is widely used in industry, such as film for electronic products, covering and protecting adhesive products, etc. PET (polyethylene terephthalate) material is favored for its excellent mechanical properties, chemical stability, and good heat resistance.
Itu produksi dari PET rilis film terutama termasuk berikut kunci langkah
- Raw material preparation: Use high-quality PET raw material particles to ensure excellent basic performance of the membrane material.
- Melting and ekstrusi: PET partikel are meleleh at tinggi suhu dan diekstrusi melalui an ekstruder to bentuk a film.
- Peregangan dan orientasi% 3a Disiapkan primer film adalah berorientasi melalui pemanasan dan peregangan proses ke peningkatan nya fisik properti.
- Release coating treatment: Apply a layer of release agent evenly on the surface of the PET film. Common release agents include silicone oil, etc. The thickness and uniformity of the release coating directly affect the release effect, so it needs to be accurately controlled.
- Menyembuhkan dan panas perawatan% 3a Yang dilapisi membran kebutuhan untuk menjadi sembuh melalui panas proses seperti sebagai memanggang untuk memastikan nya baik pelepasan dan stabilitas.
- Cooling and coiling: Setelah panas perawatan, the film kebutuhan to be didinginkan untuk coiling. The cooling rate should not be too fast to prevent uneven shrinkage of the film.
- Pemotongan dan pengemasan% 3a Sesuai ke pelanggan kebutuhan% 2c besar gulungan dari film bahan adalah potong ke dalam ditentukan spesifikasi% 2c dan kualitas inspeksi , kemasan dan pengiriman are dibawa keluar.
Sepanjang the seluruh produksi proses, kualitas kontrol adalah penting. For contoh, the temperature control selama the ekstrusi proses kebutuhan to be tepat to memastikan seragam film bahan tekstur; the uniformity of the release agent coating is langsung terkait to the use effect of the final product; the time and temperature setting of the curing stage must be strictly operated in accordance with the standar.
The production technology of PET release film is relatively high, which not only requires high-quality raw materials and advanced production equipment, but also requires high skills of operating technicians. Through continuous technological innovation and production process optimization, more high-quality and multi-functional PET release films can be obtained to meet the changing needs of the market.
