The application provides a nitrogen-containing compound and its electronic components and electronic devices, which belong to the technical field of organic electroluminescence. The nitrogen-containing compound provided by this application has polycyclic conjugation characteristics, fused indolocarbazole parent structure, high bond energy between atoms, good thermal stability, and is conducive to solid-state accumulation between molecules. In electroluminescent devices, it is shown as a light-emitting layer material with a long lifetime. A structure consisting of a benzoxazole or benzothiazole group and a nitrogen-containing group (triazine, pyridine, and pyrimidine) connected through the core structure of the fused aromatic ring; this combination makes this part of the structure have a high dipole moment, thereby increasing the polarity of the material. When the nitrogen-containing compound of the present application is used as a light-emitting layer material of an organic electroluminescence device, the electron transport performance of the device will be effectively improved, and the luminous efficiency and service life of the device will be improved.

A preparation method of phenolic fiber, comprising the steps of uniformly mixing phenolic resin and spinning improver, the mixed materials are melted and blended by a twin-screw extruder to form a melt, and then the melt enters a single-screw extruder, The fiber is sprayed out through the spinneret assembly, sucked through the aspirator, and transported to the fiber collection device by the wire feeding pipeline to obtain the phenolic fiber precursor; the prepared phenolic fiber precursor is cured in formaldehyde, hydrochloric acid, and deionized water. The pre-crosslinking reaction is carried out first in the solution, and then the second crosslinking reaction is carried out by adopting a stepwise heating method, and finally the third crosslinking treatment is carried out at high temperature. This patent effectively improves the spinning efficiency of the phenolic fiber precursor, shortens the crosslinking reaction time of the phenolic fiber, and prepares the phenolic fiber with excellent mechanical properties and high char formation rate.

The invention provides an extrusion process for producing an asymmetric special-shaped seamless tube by utilizing a circular tube. The extrusion process specifically comprises the steps of A. making auxiliary coordinate axes X and Y by using the center of a circle of an outlet of an extrusion container as an original point, wherein the axis X is a horizontal axis, the axis Y is a vertical axis, and a plane P on which the axis X and the axis Y are positioned is parallel to the end surface of the extrusion container; B. adjusting the positions of an ejector pin and a mold along the direction parallel to the plane P, so that the area of the cross section of a mold cavity is equally divided by the axis X and the axis Y, and the mold is fixedly connected to the outlet end of the extrusion container; C. leading the circular tube which is heated to first temperature into the extrusion container, and pushing the circular tube out of the outlet end of the extrusion container at first advance speed, so as to obtain the asymmetric special-shaped seamless tube. According to the extrusion process provided by the invention, the ejector pin can be prevented from rotating in an extrusion process, so that an inner cavity of a product is prevented from twisting, thereby guaranteeing normal production.

The invention relates to a multi-angle adjusting type hardware clamp. The clamp comprises a fixing frame, a second limiting through hole and a first support, wherein a first limiting through hole is formed in the left side of the bottom of the fixing frame, and a balance frame is arranged in the middle of the bottom side of the fixing frame, the second limiting through hole is formed in the rightside of the bottom of the fixing frame, and a mounting frame is fixed right above the fixing frame, the two ends of the mounting frame are connected with anti-displacement plates, the first support isembedded on the left side of the top end of the fixing frame, and the top end of the first support is connected with a sliding clamping groove, a first clamping rod is installed at the left end of the sliding clamping groove, and a second clamping rod is embedded at the right end of the sliding clamping groove, connecting through holes are formed in the bottom end of the sliding clamping groove,and fixing rods are arranged on the two sides of the connecting through holes. The multi-angle adjusting type hardware clamp has the beneficial effects that the clamp can be conveniently installed through the first limiting through hole and the second limiting through hole, and a balance degree of the two sides of the clamp can be increased.

The invention discloses a flexible screen display control method, a terminal and a computer-readable storage medium, when the area of ​​the current use area of ​​the terminal flexible screen is smaller than the area of ​​the available area of ​​the flexible screen, respectively determining the brightness of at least two unit sub-areas in the use area , according to the brightness of each unit sub-area to determine the brightness balance between the unit sub-regions, and when it is determined that the brightness balance between the unit sub-regions does not meet the balanced requirements, implement the use area expansion strategy, and strive to expand the use area of ​​the flexible screen , so as to improve the brightness balance between the unit sub-regions, avoid the brightness imbalance between the unit sub-regions, easily irritate the user's eyes, cause the user's eye fatigue problem, reduce the risk of damage to the user's eyesight, and effectively protect the user's eyesight , to improve the user experience.

The invention discloses a coating device, a coating system and a coating method for coating frame sealant. Nozzle; the tube wall of the rubber storage tube is made of flexible material, and the tube wall can undergo recoverable inward deformation perpendicular to the axis of the rubber storage tube. The invention can effectively avoid problems such as hanging glue.

The invention provides spinning method and device and a clothes treatment device. The method comprises the following steps: controlling a motor to execute a spinning process; in the spinning process,monitoring whether a user control instruction is received; if the start of receiving the user construction instruction is monitored, controlling the motor to increase the rotation speed; after the stop of receiving the user control instruction is monitored, controlling the motor to reduce the rotation speed, to execute the spinning process. According to the invention, the rotation speed of the motor is controlled by the user control instruction; the water content is lowered properly by the high rotation speed monitored by the user, so as to increase the balance degree of the inner drum; and with the inner drum balance, spinning is performed at a relatively high rotation speed, thereby increasing the spinning efficiency, and solving the technical problems of the prior art that the clothes are spun at a relatively low rotation speed in the case of inner drum imbalance and consequently the spinning efficiency is quite low.
