An apparatus for ejecting liquid droplet includes a suction table for setting a rolled work having a plurality of drawing area arranged in the longitudinal direction by suction, a delivering apparatus for introducing the work into the suction table in a sagged state, a drawing apparatus having functional liquid droplet ejection heads for drawing patterns on respective drawing areas on the work set by suction while relatively moving the functional liquid droplet ejection heads, a winding apparatus for winding the work with the pattern drawn thereon in the sagged state, and a flushing unit having a flushing box for receiving ejection from the functional liquid droplet ejection head so as to be located in at least one of the sagged portions of the work.

A writing brush printing filming device and a nano film printing method based on the device. The writing brush printing filming device comprises a writing brush device. The writing brush device comprises an outer liquid supply tube (1), a tightening tube (2), and an inner liquid supply tube (3). A plurality of protruding brush hair (5) is fixedly disposed on the inner wall of the inner liquid supply tube (3). The plurality of protruding brush hair (5) is divided into two parts. The two parts are correspondingly disposed on relative inner walls of the inner liquid supply tube (3), and tips of the two parts of the protruding brush hair (5) are intersected and put together. A circle of liquid storage hair (4) is fixedly disposed on the outer wall of the inner liquid supply tube (3) surrounding the inner liquid supply tube (3), the outer liquid supply tube (1) is sleeved on the liquid storage hair (4), the tightening tube (2) is sleeved on the outer liquid supply tube (1), and the outer liquid supply tube (1) and the inner liquid supply tube (3) in which the liquid storage hair (4) and the protruding brush hair (5) are fixed are fixed by means of the tightening tube (2), so that the protruding brush hair (5) and the liquid storage hair (4) are combined into a conical fiber writing brush point. The ultra-long functional nano film prepared by using the writing brush printing filming device has good repeatability.

An apparatus for sealing a furnace mouth of a drawing furnace and a sealing control method. The apparatus comprises: an extendable and retractable sealing ring which is provided coaxially with the furnace mouth of the drawing furnace; an air extracting / inflating device which extracts air from or inflates air to the extendable and retractable sealing ring to change the pressure in the extendable and retractable sealing ring and correspondingly change the inner diameter of the extendable and retractable sealing ring; a laser diameter measuring instrument for measuring the actual diameter of an optical fiber preform; a pressure sensor for measuring the pressure in the extendable and retractable sealing ring; and a controller which analyzes, according to the measured pressure in the extendable and retractable sealing ring and the measured actual diameter of the optical fiber preform, diameter data of the optical fiber preform to control the air extracting / inflating device to extract air from or inflate air to the extendable and retractable sealing ring, so that the inner ring surface of the extendable and retractable sealing ring always abuts against the optical fiber preform. The control method can seal a gap between the furnace mouth of the drawing furnace and the optical fiber preform.

Ball grinding mill bearing bush lubricating oil and a manufacturing method thereof solve the problem that a ball grinding mill bearing bush is poor in lubrication in the severe environment. The ball grinding mill bearing bush lubricating oil is formed by using synthetic oil as base oil and refining multiple added efficient composite additives, has the advantages of being abrasion-resisting, high-temperature-resisting, oxidation-resisting, firm in formed film and the like, and can repair wire drawing and reduce abrasion and bearing bush temperature at fastest speed. The work efficiency and the product quality are improved obviously, the repair and maintenance costs are reduced, the service life of a device is prolonged, and energy consumption is reduced greatly. The ball grinding mill bearing bush lubricating oil is composed of, by mass, mineral lubricating oil 49%-69%, polyester synthetic oil 20%-40%, thickening agent 0.05%-0.15%, organic molybdenum composite additive 2.5%-4.5%, T306 additive 1%-3%, T202 antioxygen 0.4%-0.6%, T551 metal deactivator 0.7%-0.9% and T704 antirust additive 0.6%-0.8%, wherein the summation of the components is a hundred percent.

The invention discloses a preparation process of a power cable for urban buildings. The preparation process specifically includes the steps of carrying out wire drawing, stranding conductors, extruding an insulating layer, extruding an inner sheath, wrapping a shielding layer, braiding an armor layer, extruding an outer sheath, carrying out finished product inspection and obtaining a finished product. The shielding layer is formed by wrapping an aluminum-plastic composite tape on a wrapping machine or a cable forming machine, the outer layer of the inner sheath is provided with the aluminum-plastic shielding and the armor layer to form a combined shielding layer, so that the transmission impedance of the power cable is enabled not to be greater than 1 omega / m when the shielding transfer impedance of the finished power cable is reduced to 100MHz or below, thereby ensuring the finished power cable to have good shielding performance, enabling the power cable not to cause interference to adjacent circuits when being electrified and used, and thus increasing the stability of the finished power cable in use.
