The invention provides an OLED (Organic Light Emitting Diode) encapsulation method and an OLED encapsulation structure. A titanium-doped diamond film layer is introduced into an OLED film encapsulation layer; the light transmittance, bending property, thermal conductivity and water-oxygen blocking capability of the OLED film encapsulation layer are improved by using relatively high light transmittance, relatively good flexibility, high thermal conductivity and relatively low water-oxygen transmittance of the titanium-doped diamond film layer, and then the usability and service life of an OLED display panel are improved.

A method for manufacturing a stator core (20) of an electric motor, wherein first a substantially rectangular parallelepiped-shaped sheet group (40) is formed from strip-shaped sheets (21), and the sheet group is wound around a circular shaft core in a subsequent step. The roll is deformed into an annular shape having an axial direction (a) corresponding to the cylinder axis (z), wherein the annular shape has an axial end face (46). In this case, in a further subsequent step, the annular lamella group ( 40 ) is plastically deformed in the axial direction (a) at least partially on the axial end face ( 46 ). The stator of an electric machine, in particular an automobile generator, comprises a stator core composed of strip-shaped sheets (21) wound around a circular shaft core, the stator core having axial end faces (46). The stator core is plastically deformed in the axial direction (a) on the end face (46). The stator of an electric machine, in particular an automobile generator, comprises a stator core composed of strip-shaped sheets (21) wound around a circular shaft core, the stator core having axial end faces (46). The axial length of the stator core on its inner diameter is greater than the axial length on its outer diameter.

The invention discloses a butyl rubber reactive bonding layer used for a pre-paving reactive-bonding waterproofing coiled material, a preparation method thereof, and the pre-paving reactive-bonding waterproofing coiled material, and relates to the technical field of high-molecular pre-pavement materials. The butyl rubber reactive bonding layer is mainly produced from: 100 parts of raw rubber, 9.5-15.5 parts of a linear tackifying resin containing terminal hydroxyl group structure, and 12.5-19.5 parts of active filler comprising active silicon dioxide and aluminum oxide. The reactive bonding layer solves the defects that a bonding layer of a waterproofing coiled material in the prior art is liable to flow, deform and wrinkle when being heated, is brittle at low temperature, is free of sticking feet only if a single anti-sticking layer or insulation layer exists, and is poor in stripping strength with post-poured concreted. The butyl rubber reactive bonding layer can form permanent chemical bonds with concrete, so that a real skin-type water-proofing structure is formed between the pre-paved high-molecular waterproofing coiled material and the concrete, and the bonding layer is freeof sticking feet and allows people to walk thereon without coverage by sand and coating layers. In addition, the reactive bonding layer has good low temperature resistance and thermal stability.
