SVEZA Exterior Birch Plywood is a high-quality construction material with high durability and moisture resistance. SVEZA Exterior Birch Plywood maintains its performance characteristics under conditions of high humidity and does not deform or soak. It can be used in both interior and exterior finish. Standard sizes, mm: 15251525 Standard thickness, mm: 3-21mm
SVEZA Deck 350 is a special film faced plywood with a grid pattern intended for slab formwork. It comes with 25, 50, and 100 mm grid patterns. These types of lines simplify plywood marking and cutting, as well as rebar placement. This allows to reduce labor costs at the construction site. Production process of plywood with layout grid is patented.* SVEZA Deck 350 is a high-strength plywood made of 100% birch veneer, all layeers are smooth, without cavities inside. Its edges are coated with special acrylate-based waterborne paint with low water permeability. SVEZA Deck 350 surface is smooth, and coated with wear resistant film (wearing capacity is 350 Taber test rotations). * Registered in the State Register of Utility Models RF 01.20.15, RF patent number 150519. Standard sizes: 1220 2440 8mm 1250x2500x18mm 1250x2500x21mm

Crude oil flowing from wells contain fair amount (often 20-30%, sometimes up to 60-65%) of water with dissolved salts from basis point up to 1-2%. This significantly increases viscosity of crude oil, generates stable emulsion and makes the oil inadequate for refining and transportation. Water produced together with oil is usually in very unusual state, i.e. it is spread in oil in the form of droplets (emulsified form). Less the size of droplets, more stable the emulsion. One of the main reasons of emulsion stability is also the presence of resin, pyrobitumen, paraffin, and other oil admixtures like glycerine, microcrystal of paraffin, ceresin in crude oil. These substances generate quite firm and thick (protective films) on the surface of water and solid particles thus preventing merging of water drops and solid particles and their spontaneous segregation from oil. At present physical, thermal, physico-chemical, electrical and combined methods of oil emulsion breaking are used for oil dehydration and oil desalting. One of the widelyused and most effective methods is physicochemical combined method using chemical reagents demulsifiers. Demulsifiers are substances with high surface activity. They are concentrated in interfacial areas of oil emulsion, break protective films covering solid particles, water droplets and neutralise their electric charges. After this, small droplets will merge into bigger drops under the influence of mutual attraction, loosen and segregated from oil.Oil demulsifying is carried out in oil field and oil refinery plants. At present “KARVAN-L” company tries to provide integrated work cycle: – development production supply and implementation of produced demulsifiers together with consumer. Demulsifier Karvan-200 is designed for oil dehydration and desalting in gathering system and oil treatment plant. Reagent can also inhibit corrosion processes.Demulsifier Karvan-201 is designed for separation of both light and heavy crude emulsion. This reagent is the composition of macroglycols and nitrogen-bearing surfactants in organic solvent environment Demulsifier discharge per 1 ton crude is 10-60gr. Dosage depends on emulsion stability, treatment temperature, water separation period and desired depth of oil processing. Optimum dosage and demulsifier application process ensuring necessary results can only be defined as per test results carried out in practical use sites.
