Finishing lines. Finishing of joiner's building products with paints and varnishes Finishing of joiner's building products
The purpose of finishing with paint and film materials is to give the surface of wood products (wood materials) a decorative appearance and to protect them from destruction under the influence of the external environment.
Depending on the operating conditions and purpose of the products, protective or decorative coatings are used. Finishing is divided into transparent (in which the surface of the substrate is visible) and opaque. A special case of an opaque finish is imitation, in which the texture and color of different types of wood, as well as various patterns, are reproduced on the surface or coating being trimmed.
Requirements for the protective and decorative properties of coatings
The coating film of coatings of joinery and construction products operating in atmospheric conditions should have, first of all, water and moisture permeability, preventing moisture deformation of products when environmental humidity changes. The durability of coatings, i.e., their ability to maintain desired properties, depends on their resistance to ultraviolet radiation, adhesion to wood, and a number of other factors. The requirements for the finishing of joinery products are determined by the normative and technical documentation for the products, as well as GOST 24404.
The optimal thickness of coatings on wood products should be at least 60-80 microns. Since the introduction of an antiseptic in the paint composition does not protect wood materials from damage by fungi when moisture penetrates through defective coating sites (or with high permeability of the paint film), it is necessary to antiseptic the surface of the product itself. The roughness of the front surfaces in products for opaque finish should be no more than (Rm max) 200 mm for front surfaces and 320 mm for non-front; for transparent finish Rm max) - 60-80 microns.
Surface preparation
Surface preparation includes bleaching, dyeing, filling, filling and priming.
Dyeing is the giving of wood a new color or a uniform color background with the preservation of its texture using various dyes, pigments and mordants. The most common is surface dyeing, which uses mainly water-soluble synthetic dyes for wood from No. 1 to 16. The concentration of the solutions is 2-5%.
Pore \u200b\u200bfilling - surface treatment of annular wood species with viscous pore-filling compounds.
Filling - (local and solid) is performed to smooth the surface of the wood and mask dents, scratches, cracks, etc. The consistency of most putties is designed to be applied with a spatula. To better fill the irregularities of the substrate, the dry residue of putties should be higher than soil. When filling products, especially those operating in atmospheric conditions, it is necessary to avoid thick layers of putty (more than 0.3-0.5 mm), since during operation shrinkage and cracking of the putty and, as a consequence, destruction of the coating, are possible. The application of dyes, fillers and fillers is carried out manually, by spraying, on roller and roller coiling machines МШ1.03, ШПЩ
Dyeing and pore filling are used, as a rule, in furniture decoration.
Priming of wood and wood materials is carried out to improve adhesion (adhesion) of the varnish (paint) coating layer to the substrate; reduce the consumption of more expensive coating coating composition; insulation of air, moisture and resins in the wood substrate, the release of which during application, drying and operation of the paint layer can lead to its destruction; increasing the conductivity of the surface of wood materials when painting in a high voltage electric field.
The primer can be applied by any mechanized method.
Primer compositions differ from enamels and paints with a high content of pigment (filler) and, as a rule, the nature of the film former.
Due to the lack of white primers in the decoration of carpentry-building products, enamels or paints are used as primers, and drying oil is also allowed.
Paint Drying
Drying of coatings is carried out to cure the paint layer and can be carried out either only by evaporation of solvents (materials such as nitrocellulose, perchlorovinyl varnishes and enamels), or through chemical processes of oxidation, condensation and polymerization (materials such as oil, alkyd, urea, polyester varnishes and enamels etc.). The process of natural (air) drying at 18-20 ° C of the majority of the materials used is very long (more than 24 hours) and requires large production areas. Artificial drying is the most effective means of accelerating the process of coating formation.
According to the method of supplying thermal energy, drying is divided into convection (heat transfer occurs when the paint layer is in direct contact with circulating hot air); radiation (by irradiating colored products with infrared and ultraviolet rays); due to the accumulated heat preheated by convection, thermoradiation or contact method of the product; curing the gelatinized coating layer in presses or by rolling with heated rollers.
By design, the drying chambers can be divided into two main types: dead ends of periodic and continuous through passage. The former are used in enterprises with small-scale production.
One of the promising methods of drying coatings is curing under the influence of UV radiation (photochemical method of drying). In this case, curing is carried out by converting UV radiation into heat in the paint layer itself, which significantly reduces energy loss and substrate heating. The optimal wavelength of UV radiation is 0.200-0.360 μm. The photosensitivity of the coating compositions is achieved by the introduction of photoinitiators in them - a photosensitive additive, the most effective of them are benzoin methyl and isobutyl esters, grigonal-14, etc.
UV curing is used for transparent coatings, mainly polyester. However, the successful experience in applying the photochemical method of drying pigmented compounds abroad and similar attempts by our scientists create the prerequisites for expanding the scope of its application.
Pre-heat drying
This drying method combines the advantage of thermoradiation curing (film formation starts from the substrate) and eliminates the bubbling of the coating with moisture and air contained in the wood substrate. The method is effective for coating thicknesses up to 80 microns. The degree and duration of heating depends on the type of paint and varnish material and the mass of parts. For quick-drying paint compositions (urea, water-dispersion), surface heating of the parts for 40-90 s at a heating element temperature of 300-400 ° C or air 170-180 ° C is sufficient. When stained with enamels, the heating time increases to 2-5 minutes. After application of the paint, stabilization is required (also called degassing or normalization) in ventilated unheated chambers, where the solvent is removed from the hardening paint layer.
Convection drying
To heat the circulating air in the drying chambers, steam and electric heaters are used. Practice shows that when air is heated to 60-80 ° C, steam heaters are economically preferable. The direction of the air flow in the passage drying chambers is the reverse of the movement of the conveyor with painted parts.
Thermo-Radiation Drying
In thermo-radiation drying by infrared radiation (thermal radiation), heat transfer to the paint layer is carried out mainly from the substrate, which is heated by absorption of infrared rays. Heated from below, the coating layer does not interfere with the removal of solvents, which greatly accelerates the curing process compared to convection drying. When thermo-radiation drying paint coatings on wood, one should take into account the release of moisture, air and resins contained in the substrate, as well as warpage of products at high temperatures. At a product surface temperature of 130 ° C and a humidity of coniferous wood of 14-15%, the critical drying time by thermal radiation is approximately 2 minutes: during this time, the resin in the wood does not have time to melt. However, this time is not enough to cure most of the applied paint formulations. This determines the upper limit of the surface temperature of the wood during thermal radiation drying, equal to 60-80 ° C.
As sources of infrared radiation, tube, panel and tube emitters are used. The disadvantage of tube emitters is the low efficiency and short service life. A panel radiator, which is a cast-iron or ceramic plate with heaters mounted in it (or heated by gas burners), gives a uniformly distributed radiation flux, but has a large inertia. The most common are tubular electric heaters (TEN) with aluminum NVS reflectors (GOST 13268) with a working surface temperature of the heater up to 450 ° C.
During thermo-radiation drying of lattice-shaped products (for example, window blocks), the energy of the emitters is not fully used. Practice shows that the use of combined (thermo-radiation-convection) drying for painted products of complex shape is impractical, since the curing time of the paint layer by thermal radiation is insufficient for convection drying of the internal (shielded from radiation) parts of the painted surface washed by hot air. The energy intensity of the electrothermoradiation drying chamber is significantly higher than convection.

Applications
To finish the surface of the shield parts (panels, doors), a lacquering machine LM-3 is used (Fig. 196). On this machine, nitrocellulose and polyester varnishes and enamels based on these varnishes are applied to shields. The lacquering machine is a bed on which there is a conveyor for feeding boards, varnish-feeding plants and vertically adjustable heads, and a control panel for the machine.
Shields are stacked on the conveyor, by which they are uniformly moved under the heads, forming a varnish curtain. Passing through this curtain, the shields are varnished.

Test questions. 1. Tell us about the purpose of the lines included in the OK-250s kit. 2. What are the purpose and how do the installations for processing logs for the walls of chopped houses work? 3. How is the lacquering machine LM-3 arranged?
On topic § 78. Equipment for the finishing of carpentry-building products:
- FINISHING THE SURFACES OF JOINT AND CONSTRUCTION PRODUCTS
- STRUCTURES OF THE MAIN JOINT AND CONSTRUCTION PRODUCTS
- REPAIR OF JOINT AND CONSTRUCTION PRODUCTS AND STRUCTURES
- MECHANIZATION AND AUTOMATION OF THE PRODUCTION OF JOINERY AND CONSTRUCTION PARTS AND PRODUCTS
- MANUFACTURE OF JOINT AND CONSTRUCTION PRODUCTS AND WOODEN STRUCTURES AT WOODWORKING ENTERPRISES
Finishing includes surface preparation operations: painting surfaces veneered with natural veneer, priming and putty; varnishing, coloring and printing of wood grain; polishing varnish surfaces. The composition and type of finish is determined by the material of the cladding, the type of surface and the operational and aesthetic requirements for it, costs.
In the furniture industry, sets of lines are used for printing a texture pattern on the surface of plates (priming lines and gravure lines), lines for varnishing the surface of panel parts with nitrocellulose and polyester varnishes. There are dyeing and priming lines. A feature of the finishing lines is that they include equipment for applying varnish or other material and drying plants.
Lacquering machines operate at high speeds - 60-140 m / min. The drying time of varnishes depends on the material and method of drying. Conveyor dryers, speed determines the performance conditions. But with increasing speed, the length of the drying units also increases. Typically, the line length does not exceed 100 m (U-shaped configuration). The increase in the length of the line makes it difficult to place them in existing production facilities.
Scheme line MGP-2 intaglio printing texture pattern(Fig. 148, a).Printing is made on boards with a width of 200-900 mm and a length of 400-2000 mm. The line consists of a dual loader 1, tilters 2 and 10, grinding machine 3, brushing machine 4, soil roller machines 5 and 9, drying chambers 6 and cameras 7 normalization, two-section printing machine 8 and stacker 11.
Tilter 2 turns over the details when applying the drawing to the second layer, and the tilter 10 turns parts after the first coating so that they are in contact with the same surfaces in the foot (with or without coating). This is necessary to protect surfaces from damage. The car 5 applies tone soil on the surface of the shield, prepared on a special line. The car 9 apply a protective varnish coating. Dryers are heat-radiating, in normalization chambers, shields are blown with air at a temperature of 20-25 ° C. These cameras serve to
cooling the surface of the shield and removing volatiles released from the varnish.
The composition of the varnish lines depends on the brand of varnish used. If varnishes are quick-drying, then tunnel-type dryers are used, in lines with long-drying varnishes, shields are placed on shelves loaded into chambers. Loading into shelves is done manually.

a- MGP-2 intaglio printing of texture pattern; b- lacquering of plates, double-sided; in -MPP-2 polishing of polyester coatings
Line diagram for double-sided panel finishing with polyester varnishes(Fig. 148, b)The line consists of a loading roller conveyor 1 and unloading 15, brushing machines 2 and 10, heating cameras 3, lacquer machines 4, 6, 11, 13 gelatinization chambers 5, 12, blocks of drying chambers 7 and 14, including convective and infrared dryers, shifter 8 and tilter 9. The first coating applied on machines 4 and 11 dries 5-7 minutes to a gelatinous state. After applying a second coat on machines 6 (13) the varnish is dried for 15-20 minutes until completely dry. At the same time, a group is processed on the line, consisting of shields of various sizes, stacked in the 3500 X 1800 format, which complicates the mechanization of loading and unloading the line. The use of group finishes increases the coefficient of
the utilization of the line. When processing single panels, this coefficient decreases, since mechanisms designed to skip parts of the maximum size process parts that are much smaller in area.
MPP-2 line diagram for polishing polyester coatings(Fig. 148, in).The line consists of a bootloader 1 and unloader 6, sanding machines unified with the MGP-2 line 2, conveyor belt 3 for quality control of grinding, six-shaft polishing machines 4, camera normalization 5. These lines have modifications of the U-shaped configuration.
The considered finishing lines can be used for processing parts of built-in furniture, door leafs.
Painting of bar parts of joinery construction.This operation is performed by jet spraying (Fig. 149, a).Block 1 on the conveyor 4 with shaped rollers is fed through a filler machine 3 and enters the shift position. The bar acts on the limit switch SQ1and when the plug 8 will be in the required position, the switch will be pressed SQ2,starter trips KM1and the electric motor turns on M1transfer mechanism drive. Disc 5 rotates counterclockwise, lever 2 rises, grabs the bar and transfers to the fork 8, installed on the conveyor 7. When the disc moves away 5 from the starting position make contact SQ3will close, the relay will turn on KM2,which will prepare the relay circuit KM3.It will work when disk 5 returns to its original position. (SQ3will be pressed). NC contact KM3disconnect the starter KM1,engine M1will be disconnected, and the translator will take a starting position. The bars on the conveyor 7 are fed into the drying chamber 6.
Lattice structures (chairs, window blocks) are varnished or painted in a high voltage field. The line diagram is shown in fig. 149, b.Monorail 1 carriage 2, on which detachable products are hung, transported by freight conveyors 3. The carriage, deployed along the movement, passes to the section for hanging and removing products - cameras 4 applying an electrically conductive composition and 6 - coating. Before entering the drying chamber, the carriage rotates 90 °. In the drying chamber 7, the carriage disengages from the main freight conveyor 3 and advanced by an auxiliary conveyor 8, having a low speed and a small step between grabs. At the exit of the drying chamber, the carriages are again captured by the main conveyor. The route scheme can be much more complicated, since one chamber for applying an electrically conductive solution can provide several staining chambers, drying chambers can consist of several parts, the coating is applied in several passes.
