Technology of applying wear-resistant coating to aluminium products

FIELD: technological processes.

SUBSTANCE: technology of applying a wear-resistant coating to aluminium products using a paint applying device for aluminium products containing a frame, a mechanical drive, a cliche with a paint applying device on a cliche with a squeegee, a tampolik with a tampolik drive, the cliche is in contact with a tampolik, a linear transport device (a feeder with a fastening device) of the painted aluminium products. The paint applying device for aluminium products contains, at least, one additional roller, the fastening device of the products contains two lines, each of which is located in the plane of the corresponding roller, and the applied paint is wear-resistant, with a high adhesion coefficient to aluminium.

EFFECT: increasing the productivity of application, increasing the wear-resistance of a coating, adapting the technology for aluminium products.

SUBSTANCE: invention relates to printing, namely, the means used for thermal applying of alphanumeric symbols or images on the surface of various products. Film for thermal transfer printing is a composite material formed of a set of layers, the first of which is the main-bearing, the second is separating, the third is coloring, and the layers have respective melting points, determined by the technology of film application. At the same time in one of the layers or simultaneously in several layers there is at least a portion of material which is uniformly distributed or distributed to individual sites, and having the ability to function as an optical marker in the range of ultraviolet, infrared, or X-rays radiation.

EFFECT: proposed new film for thermal transfer printing enables to identify both the film and the products on which it is applied, as well as to provide a high degree of protection against counterfeit production.

SUBSTANCE: invention relates to manufacturing of wall-paper on the basis on digital image. Method of printing wall-paper in printing system, containing main computer connected with printing devices, subscriber computer, and means of communication, providing interaction of subscriber computer and main computer, including stages: (a) setting of overall dimension of produced wall-paper, (b) transmission of digital image from subscriber computer to main computer via means of communication for formation of wall-paper pattern, (c) change of wall-paper pattern dimensions on main computer to dimensions in fact equal to overall dimension of final wall-paper, (d) dividing of wall-paper pattern with changed dimensions for printing by parts on several pieces in such way that printed pieces could be matches in order to restore wall-paper pattern, (e) transmission from main computer to subscriber computer via means of communication of several printed pieces, (f) reproduction of several printed pieces on subscriber computer display screen in order for customer to look them through, and (g) printing on printing devices of main computer of several pieces.

EFFECT: invention allows conveniently and cheaply to print custom-designed wall-paper, customer being able to make decisions with respect to correctness of piece edge location on wall-paper pattern.

SUBSTANCE: invention is related to methods for jet printing with the help of printer on polyvinylchloride (PVC) material, mostly on film PVC material used for manufacture of casement ceilings. Method includes stepwise introduction of material sections into printing area located in the area of jet printing head location. Application of dye with the help of jet printing head on material surface in compliance with information received by printer for reproduction of previously formed image. Treatment of material with applied dye for its fixation on material surface is carried out. Image is applied by method of cold printing without previous heating of material supplied to printing area and without heating of environment in specified area. Dye used is solvent or ecosolvent ink for jet printers. Treatment of material with applied dye is realised after material exit from printing area by blowing of material surface with applied dye by air with temperature of 14-25°C.

EFFECT: possibility to apply image on non-modified film PVC materials with the help of jet printer.

SUBSTANCE: invention relates to the dyeing composition for screen printing on the electric and electronic parts as well as for decorative graphics. The composition includes a solvent with the boiling point of 170°C or higher in the amount of 70 wt % or more based on the total weight of the solvent and the prepolymer or a polymer with the molecular weight of 2000 or more in the amount of 2 wt % or more in the total composition. The composition has viscosity ranging from 30 to 180 Pa⋅/Sec at 25°C and the thixotropic index within the range from 2.0 to 8.0. When using a screen printing plate with 360 cells per inch (14 cells per 1 mm), which is formed by a high-strength non-deforming stainless steel mesh made of wire with a 25 mm diameter, the width of blurred edges of the printed image does not exceed 10 microns from the specified size of the image's printing plate.

EFFECT: one-step production of printed products, with inclusing of detailed images and solid figures of large area of high quality and resolution, with no spreading or flaking with sharp edge sections of the image on solid figures and an increased leveling capacity.
