    5. Apparatus. lacquer coatings based on radiation-curable polymeric materials on a product containing lacquer sprayers, an irradiation chamber connected to an inert gas source, an ionization radiation source installed in it, and installed directly at the entrance to the chamber a vestibule to prevent inert gas leakage, characterized by the vestibule is made in the form of a vacuum shutter with
    external and internal sluice gates / in which lacquer sprays are installed.
    The invention relates to a technique of applying lacquer coatings on products using radiation-curable polymeric materials, in particular, from electronic radiation, in which the exposure to the product is in an inert gas atmosphere ..
    A known method of applying lacquer coatings based on radiation-curable polymeric materials on a product consists in spraying the varnish with compressed gas on the product and subsequent ionization irradiation of the layer of varnish on the product in an inert gas atmosphere in the irradiation chamber 1}
    The disadvantage of this method is that it does not exclude the ingress of air oxygen into the lacquer coating during the spraying of the varnish onto the product and transporting it to the irradiation chamber, which is especially true when applying coatings on complexly shaped products, The irradiation chamber, from the cavities and holes, diffuses the residual oxygen, which actively reacts with the radicals formed in the varnish when irradiated, forming a stable compound, t. e. at this point, no chain elongation occurs, but only a slight formation of a network structure with a relatively low polymer molecular weight on the surface. At the same time, the surface does not become scratch resistant. A very thin film layer can be removed with a solvent.
    It is also known a device for carrying out this method, comprising lacquer sprayers, an irradiation chamber connected to a source.
    an inert gas, an ionization radiation source I installed therein and mounted directly at the entrance to the chamber of a vestibule to prevent leakage of the inert gas fl.
    The drawback of the device is that the lacquer is applied to the substrates and transported to the irradiation chamber in the air a.i; r rsphere, which leads to the ingress of air oxygen into the lacquer coating.
    The purpose of the invention is to determine the quality of the coating by eliminating the ingress of oxygen into the varnish layer.
    The goal is achieved by the fact that according to the method of applying lacquer coatings based on radiation-curable polymeric materials on.: Product, consisting in spraying varnish with gas on the product and subsequent ionization irradiation of the varnish layer on the product in an inert gas atmosphere in the irradiation chamber, before irradiation from - dividing the package with the coating through the external sluice gates, a vacuum shutter is located directly in front of the irradiation chamber, from which air is then pumped out and inert gas is filled. to atmospheric pressure, and then through the inner sluice gates product is introduced into the chamber and return the product after irradiation in a vacuum zatvsfg filled with inert gas, from which the product is withdrawn after closing the sluice gate and internal outer sluice gate opening.
    .tfpk this lacquer 1 is placed on the product with a vacuum shutter filled with inert gas, and inertNel gas is used as a compressed gas for spraying.
    Before filling the vacuum shutter with an inert gas, a vacuum of at least 1 mbar is created in it.
    In addition, the lacquer coating is irradiated with electron radiation with an energy of 150-400 keV.
    In a device for applying lacquer coatings based on radiation-cured polymeric materials on a product containing varnish sprayers, an ionization irradiation chamber connected to an inert gas source, an ionization radiation source installed in it and mounted directly on the entrance to the chamber to prevent leakage 15 inert gas, the vestibule is made in the form of a vacuum shutter with external and internal sluice gates, in which lacquer sprayers are installed.
    FIG. 1 schematically shows a 20 device; in fig. 2 and 3 - variants of its implementation.
    The device contains external sludge gates 1 with integrated radiation shielding, a vacuum inert gas suction head 2, a nozzle 3, a product attached to a vacuum pump (not shown), the top view of which is indicated by position 4, and the bottom view - by position 5, inert gas supply pipe 6, internal sludge gates 7 to the irradiation chamber 8 with Integrated X-ray shielding, radiation source 9 -, rotary device 10 for the product mixing in the lines of 35 11, screen 12 for X-rays and release pipe 13 of the inert gas pipe 14, the air outlet. The device in FIG. 3 includes movable sluice gates 15, 40, a seal 16 for the vacuum with a vacuum shutter and an irradiation chamber, a seal 17 of the rod 18 moving between the vacuum shutter and the irradiation chamber.
    The device works as follows.
    Example, (Fig. 1). Coated in inert gas through the external sluice gate 1 is introduced into the vacuum shutter 2 for the inert gas. After the external sluice gates are closed, the air is pumped out of the vacuum gate to a pressure of 1 mbar or lower, then the gas is filled with inert gas to atmospheric pressure), 55 internal gates 7 are opened and the product is transported to the irradiation chamber 8, the gate gates 7 are closed, the product is moved by the sub-source 9 of the radiation, rotated, again moved under the 60 source of radiation 9, the sluice gates 7 are opened, the first product is returned to the vacuum-gate 2, a second product is introduced here, which is prepared for transfer to the chamber 8 j
    irradiation during irradiation of the first product. After the second product is introduced into chamber 8, the first product is withdrawn from the vacuum gate and the third product is fed into it. d.
     The total flow rate of the inert gas is limited by the creation of an inert gas atmosphere in the irradiation chamber 8 by flushing the chamber and an inert gas in an amount corresponding to approximately 10-20 times the volume of the irradiation chamber, as well as filling the inert gas with an inert gas after the gas; sluice operations in vacuum.
    PRI me R 2 (Fig. 2). A pallet G with several products 1 is removed from a spray dispenser (not shown) where the products are coated with varnish in an inert gas medium, are introduced through a sluice gate 1 into a vacuum shutter 2 FOR an inert gas, after which the gate gate 1 is closed and deflated; the air from the vacuum shutter 2 to 10 mba is then filled with inert gas to atmospheric pressure, the slag gate 7 is opened, and the pallet with lacquered products under the radiation source 9 in the irradiation chamber 8 is opened at such a rate that the varnish receives the required dose radiation for crosslinking .; The sluice gates 7 are closed, the second pallet is introduced into the vacuum shutter, the first pallet is turned, the sluice gates 7 after the pumping operation and filling the vacuum shutter 2 with the second pallet with an inert gas, are opened again. The second pallet is irradiated from above and the first from below. Then the second pallet is pressed, the first pallet is removed from the vacuum shutter and. at the same time, a third pallet is introduced into it.
    P and me 3 (Fig. 3). In this device, the pallet with the product is fixed to the mobile sluice gate 15.
    The product transported in an inert gas medium is fed from above into the vacuum chamber shutter 2 for the inert gas. The lid (not shown) of the shut-off shutter is closed and air is sucked from it until it is allowed to go from. 1 to 10 2 mbar; the vacuum shutter is filled with inert gas to atmospheric pressure. The sluice gates 15 with the product are moved with the help of the rod 18 under the radiation source 9 at a speed / corresponding to the receipt of the necessary radiation dose.
    In the final position, the product is rotated using a rod 18 and transported under an electron source of radiation when the back side is irradiated again into the vacuum shutter 2. The product is withdrawn from the vacuum shutter, the second product is introduced and the air pumping out of the vacuum shutter 2 is repeated. then the cycle repeats.
