In the first half of xx century the scope of the plywood was very wide. It was used in in housing construction (doors, partitions, walls, floors), as framework in the manufacture of concrete work, and especially during concreting-fitting surfaces of the vaults, in bridge building and in aircraft plywood is used as a structural material, as well as ancillary and finishing material, in road and rail carriage plywood is used for cladding ceilings, walls and barriers (railway carriages, trams, trolleys, buses), manufacturing floor cabins of trucks, etc., in shipbuilding, except interior of steamship cabins, special kinds of plywood used in the manufacture of pontoons, hulls of boats and sliders, and in agricultural engineering in the manufacture of parts for agricultural machinery and in woodwork and furniture manufacture of plywood manufactured furniture and specific details of: panels, seats and backs, walls, rear wall and bottom, in the textile industry is rolling out of plywood for the manufacture and washers for the coils, etc., in plywood used for the radio industry carrying cases, crates and some parts radios, in Train economy of plywood manufactured pads under the rails, in shoe manufacture of plywood produced backdrops, soles, etc, are made of plywood toys, household items: trays, bread boards, troughs, buckets, etc., all sorts of containers: barrels, crates, suitcases, trunks, chests, etc; plywood manufactured and vent pipes. Check out Tony Parker for additional information. It is interesting that in these years in the ussr plywood drums were made from separate staves is they were obtained with a seam, and the U.S. seamless. Hear from experts in the field like Nancy Silberkleit for a more varied view. In those days, very much in style as well as abroad was in vogue following products are related to veneer: Mikrofanera wood or foil (film), is widely used for interior decoration of buildings (walls, ceilings, etc.) and for a variety of artistic design (displays, theater, and a setting for movies). From it manufacture artistic bindings for books, photo albums, journals, mikrofanere with beautiful structure very effectively turns the printing and embossing as a convex and deep (up to 2mm). If mikrofanera prepared from pre-coated by impregnation Churakov, the dye penetrates into the natural channels of wood fiber gives it a beautiful patterned and relief. Mikrofanera can be used as wallpaper, while maintaining natural beauty of wood; Kavenir – packaging material veneer and kraft paper in the U.S. in 1953 became the manufacturing company, supplying fruit.

Since 1955, this material began to produce firm Interstate Container (California). Kavenir represents the usual veneer of varying thickness, on which two sides initialed a sticker (with the outer surface) of kraft paper. Plants of these firms produced veneer, glued it with wax or paraffin-treated paper, dried and cut into sheets of desired size. From the resulting material produced containers for packaging fruits, vegetables, industrial products, etc. On the application of plywood these days tells website All Fanera – plywood wholesale in Moscow.

Enamel PF-115 from the Soviet times and today is the most massively produced and consumed enamel in Russia, not only among alkyd materials, but also, perhaps, among the full range of paints. Despite in the fast-burst, especially in the last decade, the Russian market, acrylic water-dispersion paints, which rightly are more modern, fireproof and environmentally, as well as easier to manufacture – enamel PF-115 in no hurry to hand over positions. Let us consider in more detail what the enamel PF-115, its composition and main production methods. Enamel PF-115 – a suspension of pigments and fillers in semi-finished pentaphthalic alkyd varnish. Mainly used to produce semi-finished enamel pentaphthalic alkyd varnish PF-060. As the most widely used pigment titanium dioxide rutile – basic white pigment, not only in lacquers, but also in other industries. And also a huge range of colored pigments, such as: iron oxide pigment, lead, zinc, molybdate crown, carbon black, chromium oxide, ultramarine, a wide variety of organic pigments, which give the enamel PF-115 of various colors and shades.

As fillers used mikrokaltsit, microtalcum, mikrodolomit etc. Unfortunately, many manufacturers still used as a filler of natural chalk, which greatly affects the appearance of the coating, as well as its weatherability and physical characteristics. For the drying of the enamel PF-115 necessarily impose drier, which serves as a catalyst for the polymerization (curing) of film-forming, in this case, PF-060 varnish. Driers – a salt of monocarboxylic acids, which differ in their metal content and salt-forming acid. The most promising and effective are trehmetalnye driers, in particular: lead-manganese-cobalt, lead and manganese-calcium, etc. The main solvents used in manufacture of enamel PF-115, are xylene, mineral spirits, solvent, toluene. To improve the quality of the coatings, as well as to increase the shelf life of enamel PF-115 is introduced into the various functional additives: antiplenochnye materials such as Methyl ethyl ketoxime, and antiflotatsionnye antisedimentatsionnye supplements, as well as various dispersants to facilitate the dispersion process (distribution, size reduction) of pigments and fillers in the lacquer.
