Zinc is a bluish-white, lustrous metal. It is brittle at ambient temperatures but is malleable at 100 to 150C. It is a reasonable conductor of electricity, and burns in air at high red heat with evolution of white clouds of the oxide. Plating thin layers of zinc on to iron or steel is known as galvanizing and helps to protect the iron from corrosion.

Proofnasteel (proof list) is one of the universal materials of zinc galvanized steel that uses in building for construction of walls and interfloor partition (pouring-in flooring). Proofnasteel also uses like a covering material or in the capacity of roof floor. What does mean this material? Profnasteel is the profiled lists, fabricated from zinc galvanized steel (from0, 4 to 0, 1), which may be with polymer coating or without it. Proofnasteel has species diversity which differs with their thickness and size. All of these make possible to choose roof covering more suitable just You. Proofnasteel uses for construction of walls, fences and in fencing (fences of proofnasteel), but often in the roof materials ( roof Proofnasteel). Proofnasteel proof even in adverse weather conditions distinguishes from durability, simplicity of assemblage and has light weight. In the production of zinc coated proofnasteel uses zinc-galvanized steel of famous Russian and world producers. It gives guaranty that Your proofnasteel will be in high quality. Shaped sheet often uses in individual and low building, for example, in the construction of cottages, small magazines, refueling stations and booth. The main advantage of proofnasteel is its durability. Besides, this building material has many positive characteristics: proofnasteel is simple in installation, convenient for transportation, also distinguishes with its external high aesthetic view.
Naphthenic acids and their derivatives are widely used in more than 40 sectors of national economy. Naphthenic acids in a form of lead, manganese, zinc, ferrum, aluminium, chrome salts and in a form of other derivatives, are used in preparation of paint driers, varnishes, paints. Free naphthenic acids are used as a part of inks and improves their mobility. These acids are also used as thinner for aniline colorants, sleeper impregnation material preserving wood from rotting. Both free and derivative naphthenic acids have effective fungicidal, insecticidal, bactericidal and preservative parameters which are used in weed and pest control, for impregnation of wood, sail fabric, canvas, rope, tarpaulin, fishing gear and other materials regularly affected by moisture, bacteria, pest, etc. Lead, chrome, cobalt and manganese salts of naphthenic acids are used as antistatic, antideteriorant and antifoam additives for fuel, jet engine fuels and oils. Lubricating and emulsifying materials used for cooling of shearing machines, pasting, lubrication grease for high-pressure plants, demulsifiers brea-king petroleum and oily emulsions are based on naphthenic acids. Simple and compound ethers of naphthenic acids are used as plasticizers for production of polymeric materials, general rubber goods, polyvinylchloride plastic, hydraulic liquids, etc. Naphthenic acids are successfully used even at cleaning of rareearth elements, extragens of radioactive materials, catalysts, oxidation and oxonation processes, agricultural growthregulating substances, drying accelerators for glassreinforced polyesters, etc. In order to meet consumer needs for naphthenic acids, “KARVAN-L” company has developed technology and established commercial installations for output of high-purity acids.
Toolroom having efficient precise equipment can fast and in workman-like manner to produce production tools: details pressurization from plastic and rubber, including additional remote fueling connecting, moulds for 2 colored founding. demention of pressing details 1000x1200mm, mould weight to 3000 kg, stableness 60-100 thousand snatching. For improvement details setting, appearance qualitative of shape mould elements executed from stainless steel with grade 40×13 thorough work surface polishing. Forms for founding under pressure of from aluminum alloy and zinc alloy. Maximal measurement casts 1000×1200 mm, forms weight to 3000 kg, stableness 50-80 thousand snatching. Different die tooling including die tooling for fine blanking details on moulds threefold actions, providing shear purity not lower RA 1,25 and dimensional accuracy up to 7 finish, which excludes ancillary details mechanical revision (grinding). Labor componentry are practically gapless (gap between labor parts is 0,005mm), executed from steel X 12M, maximal sizes of operating groove500x600mm, stamp stab-leness up to 300 thousand snatching. For stamp stableness decreasing it is possible variant labor componentry with hardmetal alloys usage. Instrumental equipped by highly productive equipment and unique machine CHPU Fanuc. For increase of durability of casting forms lowtemperature galvanization is applied. Plant has unique site of fine blanking on presses of triple action with force of slash form 50 up to 240 tn per sec. Enterprise has facility to get orders for manufacture of blanking, pressforms and forms for casting under agreed prices. Term of manufacture is from 1 up to 6 months depending on complexity of arming. The workshop realizes complete cycle of pressforms casting. Projection of arming is realized by appliance of engineering modeling programs. Development of technologic programs of mechanical processing Manufacture of details on boring, turning machine Milling, thermal treatment, profile, round, optic, coordinate polishing, erosion weaving, wire cuts Benchwork, polishing and mounting Besides pressforms the workshop manufactures stamps, appliances, spare parts to equipment and other items. Subsidiary services operate, also repair, service of the equipment, tool grinding. Personnel of technical department and of the workshop possesses great experience in projection and manufacture of pressforms. Documentation in technical department on arming passes agreement, and technical development. Technological programs of machine processing are established, tool of second tranquility is projected.
