Edge-self-sealing quantum dot film

The invention relates to a quantum dot film, particularly an edge-self-sealing quantum dot film. The edge-self-sealing quantum dot film is provided with a quantum dot layer, wherein a water oxygen barrier layer is respectively arranged on the upper and lower surfaces of the quantum dot layer; the quantum dot layer is composed of liquid microcapsules, quantum dots, dispersed particles, a matrix resin and a film forming aid; the liquid microcapsules are uniformly distributed in the quantum dot layer; each of the liquid microcapsules is provided with a liquid capsule core; and a solid capsule wall is arranged outside each liquid capsule core. After the edge-self-sealing quantum dot film is cut off, the liquid microcapsules at the notch can be cut off, the film forming liquid in the liquid microcapsules can seep and be fused mutually, and the liquid can implement homogeneous immersion on the film edge under the action of surface tension; and the liquid can be cured to form a film under the condition of normal temperature, heating or ultraviolet irradiation, thereby performing a sealing function on the edge of the quantum dot film. The sealing process is not limited by the edge contour of the film, and the edge-self-sealing quantum dot film can also have a sealing effect on the internal edges of complicated film edge contours or locating hole films.

Manufacturing method for X80 pipeline steel spiral welded pipe

InactiveCN105817844AIncrease the groove depthSmall grain sizeProduct inspectionMechanical equipment
The invention belongs to the field of mechanical equipment manufacturing and particularly relates to a manufacturing method for a spiral submerged arc welded pipe. A manufacturing method for an X80 pipeline steel spiral welded pipe includes the following technological steps that uncoiling and flattening of an X80 pipeline steel plate coil are conducted; edge milling is conducted; pre-bending is conducted; forming is conducted; pre-welding is conducted; internal welding is conducted; external welding is conducted; pipe end expanding is conducted; and product inspection is conducted. Brand new design is conducted on a welding groove type, and therefore energy of a welding line of an inner weld bead and energy of a welding line of an outer weld bead are distributed again, the energy of the welding line of the outer weld bead is improved, and the energy of the welding line of the inner weld bead is reduced. The grain size in a critical coarse-grain area in a heat-affected area can be obviously reduced due to the reduction of the energy of the welding line of the inner weld bead, scattering of distribution of chain-shaped M-A components is facilitated, meanwhile, the size of the M-A components can be reduced, and therefore the toughness of the welding heat-affected area is obviously improved. In addition, although the filling amount of the outer weld bead is increased to some extent, a double-wire tandem sequence is changed into a three-wire tandem sequence for welding, the welding speed can be ensured, and the production efficiency cannot be reduced.
