The putty is obtained by dispersing pigments and fillers of the Bisshing Mill of Heavy Type or in a ball mill. The main purpose is to align the cast iron surfaces of the machines.
Puttailing with metal or rubber spatulas is possible both solid all over the entire surface of the machine and local. Putty apply a layer with a thickness of up to 1 mm; After drying for 4 hours at 18-220C or for 1 hour at 60-700C, the layer of putty is subjected to dry or wet grinding.
With the development of new technologies, modern machines and mechanisms are becoming more complicated and more expensive, and ideal conditions for their content are not always created in production workshops. Made predominantly made of metal, machine tools require reliable and high-quality surface protection against humidity, intensive effects of chemicals, as well as mechanical damage. The German company Lankwitzer Lackfabrik has developed a group of special paintworks for machine tools of various profiles and destination.
Paints, soils and enamel Lanquitzer prevent the appearance of corrosion, protect the surface of the equipment from harmful effects: chemical (ingress of oils, petroleum products, acids, alkalis) and mechanical (scratching, abrasion, cracks). In addition, the metal surface of the machines is often uneven, with welds and with other defects, so much attention is paid to how the lankwitzer paint coating will look after applying and during the entire operation.
A 2-component epoxy primer with a high content of anti-corrosion additives has proven itself well - SG64. The thixotropic properties of paint provide low viscosity during spraying and fast "setting" with the surface, without spreading, and high adhesion to the metal and shelterness allow you to create a uniform solid coating. This soil effectively protects the working surfaces of corrosion machines, as well as from chemical exposure and excessive humidity. In a pair with SG64, you can use homogeneous or structural enamel based on acrylic and polyurethane from the PD series.
If it is suitable for protecting light equipment from chemicals and moisture, for example, a single-layer PD 39 database based on acrylic, then heavy machine-tooling requires a stronger coating like a two-component epoxy enamel SD 67 - solid when drying, chemically resistant to alkalis, acids, petroleum products and oils. Such enamels require pre-priming a metal surface. Some types of coatings can be applied in two layers to achieve the maximum protective effect.
In the laboratory, Lanquitzer has structural paints, fully hiding defects and irregularities of the metal surface. They are applied to a uniform layer and create a dense, holistic, well-looking coating. Practically universal in use can be called a PD 48 structural coating based on acrylic polyurethane. This two-component paint can be applied to the prepared surface without prior priming, while ensuring the full protection of machine-made equipment from corrosion, shock loads and influence of chemicals. If necessary, the reinforced anti-corrosion protection PD48 can be used in combination with the soil of SG64.

After the machine is renovated and the question arises, than and how to paint it. Several demands are made to the color of the machine:
- Protection of the surface of the machine from corrosion (humidity, temperature differences)
- Mechanical exposure resistance (scratches, abrasion, chips, cracks)
- Chemical exposure resistance (oil drying, coolant)
- Preserving the appearance of the paintwork during the entire period of operation
Stages of work on coloring
For the painting of the metal surface, it is desirable to apply a three-layer system, and better four-layer coating:
- Adhesive primer layer - Must be tumbling and elastic, contain a soft resin with high adhesion;
- Shpaklevka - without applying putty, it is impossible to obtain a flawless, smooth and brilliant surface of the color of the metal;
- Primer layer - the primer layer should communicate color color and therefore contain a sufficient number of well-figmeters;
- Coating, paint - The coating layer provides the entire coating of an impeccable surface.
If necessary, you have to apply more than four layers of coatings, i.e., some of the four layers have to be applied several times. A stitching, except for normal putty, is used to be used to be straightened, which is applied to separate areas of the stained product with strong surface defects.
All work on staining the surface of the machines is reduced to the following sequence:
- Preparation of the surface of the machine - cleaning from dirt, rust, old paint Application of primer and putty, alignment of the surface;
- Painting - applying paints on the prepared surface;
- Drying of the painted surface.
1. Preparation of the surface of the machine to paint
Cleaning the surface from dirt, rust, old paint
Cleaning the metal surface is necessary to improve the adhesion of the paintwork and corrosion properties of the painted surface.
The surface should be cleaned from old paint, which, if not to remove, it may not give fresh paint to the surface as efficiently as possible.
To remove dirt, rust, old paint from the surface of the machines there are several ways:
- Mechanical - cleaning with shabra, wire brushes, skins or with a sandblasting machine;
- Chemical - removal of old paint washing with White spirit, turpentine, acetone, etc. or 5-10% alkali eating solution at a temperature of 80-90 ° C, followed by washing water;
- Thermal - Removal of paint with a soldering lamp flame and other means.
The best way to clean the surface of the corrosion machine is sandblasting or shot blasting. Cleaning is much facilitated, also by applying the power tools.
Primer, putty and alignment of the surface of the machine
After cleaning the surface of the machine, it is necessary to degrease both primer. The soil layer protects the surface from corrosion and, most importantly, must contain a resin with high adhesion - dying and elastic. The primer is produced by a brush manually, with a sprayer or dipping, if the details are small.
A 2-component epoxy primer with a high content of anti-corrosion additives has proven itself well - SG64. Thickotropic properties provide low viscosity during spraying and fast "setting" with a surface, without spreading, and high adhesion to the metal and shelterness allow you to create a uniform solid coating. This soil effectively protects the working surfaces of corrosion machines, as well as from chemical exposure and excessive humidity. In a pair with SG64, you can use homogeneous or structural enamel based on acrylic and polyurethane from the PD series.
The primed surface is again degreased and put off in order to align it and improve the appearance of the coating. The thickness of the spacing layer should not exceed 2 mm. Spaklyka is applied to the surface with rubber, metal or wooden spatulas.
One of the new products in this area is automotive swamp with fiberglass hardening, Especially convenient for filling large dents.
After drying the putty, it is thoroughly grinding, polished until the smoothing of all irregularities with the help of the skin number 80-100, and the final - pimpe or waterproof skurt. Grinding is much facilitated by the active use of power tools.
Before the color must be degreasing (antisilicone or degreaser), dust, oil, fat are removed.
2. Staining machine
Painting machines can be made both disassembled and assembled. If you need to squeeze individual nodes, then they are usually removed from the machine, and then, after painting, are set back.
Usually, for better color, you need to dry and paint every part, which is in the machine device, since the subsequent normal operation of the machine in operation depends on each part.
Surfaces are painted only clean and smooth. You can paint with spraying or brush. Usually, paint before applying on the product is filtered through a metal sieve with 1600-2400 holes per 1 cm2. The repeated layer of paint can be applied only after the previous layer of drying, giving the machine a beautiful appearance.
The active domestic normals for the color of metalworking machines are provided basically only two colors - gray and green. Other colors available in Normals are designed for coloring of signal-warning equipment and other artistic design departments of equipment Developed proposals for expanding the range of colors for the color of the outer surfaces of metalworking machines.
Selecting paint
To solve a comprehensive protection and improvement of the appearance of the surface of the machine tools, special paints have been developed, for example:
- Polymeron - Uretteo Metal Special Metal + Phosphogrun - quick-drying phosphating ground for metal;
- PD-39. - Structural polyurethane single-layer paint based on acrylic;
- PD-48. - Structural polyurethane paint based on acrylic polyurethane.
Not bad alternative to special paints - car acrylic enamel and two-component epoxy soil. Automobile paints were originally created for unfavorable conditions.
To obtain a high-quality surface, it is better to use an airless (electric) sprayer or with a compressor. A manual way of coloring is also possible, however, most often, the quality drops and more time is spent.
It is convenient to use aerosol paints. They are easily applied, provide high painting performance, and also allow painting with different colors and do not require the use of additional paint equipment.
In automotive stores, you can also choose a variety of auxiliary materials, protective tapes, means for removing drowshes, special protective clothing.
3. Drying
Drying is performed at a higher air temperature than at the time of staining, preferably in the drying chamber, then the paint will stay on the metal in the best possible way. But you can use infrared heaters.
4. GOST 22133-86
For painting equipment in industrial environments, it is necessary to adhere to the requirements GOST 22133-86 Coatings of paintwork metal-cutting, blacksmith-presses, foundry and woodworking equipment. General requirements and GOST 9.032. Paint coatings. Groups, Technical Requirements and Designations.
The standard applies to painting a metal-cutting, forging, presses, foundry and woodworking equipment, including robotic technological complexes, establishes general requirements, color, texture and classes of paint and varnishes
The following gamma colors are recommended: green, light green, gray, blue, gray-blue, cream dark, cream light. The above colors can not serve as a standard or standard color. Each type of machine requires an individual creative approach. On the pages of the magazine "Technical Aesthetics" a lot of attention is paid to the aesthetic culture of production, especially in the scientific approach to the color of the equipment and premises of the workshops.
