FIXING FILM, HEAT FIXING APPARATUS, AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240045359 titled 'FIXING FILM, HEAT FIXING APPARATUS, AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS

Simplified Explanation

The patent application describes a fixing film with an endless shape, consisting of a base material, an elastic layer, and a release layer. The release layer contains a tube filled with a fluorine resin, and the ratio of xe to xm is 1.20 or higher. The x-ray diffraction peaks of the release layer show a maximum strength at 2θ=17 to 19° (ic) and at 2θ=39.5 to 40.5° (ia). The ratio of ic to ia is defined as x. xe represents the average value of x in an edge region, while xm represents the average value of x in a central region.

  • The fixing film has an endless shape and is composed of a base material, an elastic layer, and a release layer containing a tube filled with a fluorine resin.
  • The ratio of xe to xm is 1.20 or higher, indicating a higher concentration of x in the edge region compared to the central region.
  • The x-ray diffraction peaks of the release layer show maximum strengths at specific angles (2θ=17 to 19° and 2θ=39.5 to 40.5°), which are defined as ic and ia, respectively.
  • The ratio of ic to ia (x) provides information about the crystalline structure of the release layer.

Potential Applications:

  • This fixing film could be used in various industries that require a strong and durable adhesive, such as automotive, construction, and electronics.
  • It can be applied as a protective layer for surfaces that need to withstand high temperatures, chemicals, or wear and tear.

Problems Solved:

  • The fixing film provides improved adhesion and durability due to the presence of the fluorine resin in the release layer.
  • The specific composition and structure of the release layer enhance the film's performance and reliability.

Benefits:

  • The endless shape of the fixing film allows for easy application and customization to different surfaces and shapes.
  • The fluorine resin in the release layer provides excellent release properties, making it easier to remove the film without leaving residue.
  • The high ratio of xe to xm and the specific x-ray diffraction peaks indicate a well-controlled and optimized crystalline structure, resulting in improved performance and stability of the fixing film.


Original Abstract Submitted

a fixing film having an endless shape, comprising at least a base material, an elastic layer, and a release layer in this order, the release layer comprising a tube containing a fluorine resin, and a value of xe to xm is 1.20 or more, where when, in a chart of an x-ray diffraction peaks obtained by measuring the release layer with a reflection x-ray diffraction method, a maximum x-ray diffraction strength at 2�=17 to 19� is defined as ic, a maximum x-ray diffraction strength at 2�=39.5 to 40.5� is defined as ia, and a value of ic/ia is defined as x, xe represents an average value of x in an edge region, and xm represents an average value of x in a central region.
