Urgency
One of the most pressing challenges of the new construction and maintenance of existing buildings and structures is a hydro-protection and restoration of the bearing capacity of building structures. Water acts on structures in the outer or inner side
(atmospheric and groundwater).
In the spring thaw raises the groundwater level (GWL), which interact with mineral and organic particles, change their chemical composition and concentration. Groundwater level fluctuations activate the leaching of lime in concrete structures. Rainwater captures from the atmosphere of a large number of gaseous industrial emissions. Is converted to the acid rain solution destroying concrete, marble, silicate bricks, this increases the number of pores, capillaries, and cracks.
For protection of various constructions from surface wear and cracking, i.e. from the harmful effects of water and aggressive environment use various waterproofing materials (based on cement, bitumen, polymer).
Urgency
Relevant environmental, technical and economic problem in many countries is the utilization of sulfur formed as waste oil and
gas, the amount of which is increasing every year, reaching several million tons.
Processing of low-cost sulfur is economically viable and could solve the environmental problem in any
region.
The pollution of the environment sulfur dust, which in windy weather spreads
over long distances. Are often sulfur dust explosions occur.
LLC «Gubkin E & TC» has developed a unique product - a waterproof coating on the basis of polymeric sulfur,
which would solve two problems at once: 2
•- problem of disposal of the sulfur formed as a departure of oil and gas processing, the amount of which is increasing every year
1
•- the problem of new construction and operation of existing buildings and structures associated with waterproofing and repair of building structures (foundations, etc.) exposed to groundwater, surface water and industrial waste waters, adverse climatic factors
The application of waterproofing coatings based on highly polymerized sulfur
The lining and protection of underground facilities
Waterproofing underwater, waterworks
Waterproofing dams, bridge piers, quays
Waterproofing pools, reservoirs, ponds
Waterproofing of building structures in the disposal of
chemical waste
Examples of constructions which can be used for waterproof coating on a highly polymerized sulfur:

Market
• Construction is one of the most important sectors of the national economy. Its condition largely determines the level of development of
society and its productive forces.
• Along with the development of the construction industry is growing demand for high-performance waterproofing coating. Existing on the market waterproofing materials have a number of drawbacks, such as high cost, low efficiency, fragility, low resistance to aggressive media,
etc.
• Thus, an innovative product - the waterproof coating on the basis of a highly polymerized sulfur will be worthy competition to existing
waterproofing materials on the market and the demand is expected to be high.
Areas of use of an innovative product
Thus, the implementation of technology applied waterproofing coating can be carried out at the plants by entering additional workshops, as well as at the location of the object, using compact equipment necessary for the application of a waterproofing coating.
Waterproofing at during manufacture of building
materials
Waterproofing on stage repair of
finished constructions
Technologies of drawing of waterproofing coating based on a highly polymerized sulfur on building materials:
Complete impregnation
• In the first method the impregnation is carried out by dipping the product in the chamber with the melt impregnation of polymeric sulfur. This flow chart is best suited for permanent installation, for example, at an operating plant of concrete products as a complementary technology unit in which part of the products produced by the plant can be processed in the melt of polymeric sulfur. Possible to use this method for operating a mobile unit in which the impregnation products operate on site immediately before installation (for example, prior to impregnation pile elements clogging or zero cycle before their installation). The first method is used when processing prefabricated usually new, not yet assembled products. The depth of infiltration is provided and monitors the flow rate of the solution in the bath for impregnation cycle.
Surface impregnation
• By the second method the melt polymeric sulfur applied to the surface of structures by brushing, rolling, spraying, or by another similar device. The method can be used for precast have not yet mounted structures and elements for existing buildings, including at their repair or reconstruction.
Embodiments of an innovative product
1
•Construction of the production of polymeric sulfur and sales of waterproofing material as to the factories that manufacture building materials, as to individuals willing to repair the building structures.
2
•Construction of the production of polymeric sulfur and maintenance of commercial production of a new product at the plant, produces building materials, and, accordingly, sales of a new product - "a building material with a waterproofing coating."
The calculation of the construction unit for production of polymeric sulfur capacity - 6000 tons / year. This will
get the following amounts of development of technology:
The impregnation of concrete• Complete impregnation requires the
consumption of a building material for 1m3 approximately 6kg, which will handle about 1 000 000 m3 of building products.
• A melt flow of polymeric sulfur per 1m2 for surface treatment is 0.8-1.0 kg. It will handle more than 6000000 m2 of surface.
The impregnation of bricks• Complete impregnation of one brick
requires the consumption of 0.11 kg of polymeric sulfur, which will handle nearly 54 mln bricks.
• In 1m2 masonry contains 51 brick, hence the polymer sulfur flow rate per 1m2 at full treatment is 51 * 0.11 = 5.61 kg.
• A flow of polymeric sulfur per 1m2 for surface treatment is 0.8-1.0 kg. It will handle more than 6 000 000 m2 of surface.
• In 1m3 masonry contains 394 bricks, from here on 1m3 brick masonry with full treatment takes about 394 * 0.11 = 43.34 kg.
Technological scheme of the unit for the preparation of polymeric sulfur in
3D
Overview of the equipment needed to produce polymeric sulfur
1. Storage tanks and sulfur stabilizer, equipped with electric paddles and heating jacket, coolant - superheated steam.
2. Reactor-mixer for preparing a composition of liquid sulfur and stabilizer: equipped with a paddle stirrer with electric and heating jacket, Heat carrier - superheated steam.
3. Fridge-crystallizer scraper, refrigerant: cooling water or liquid propane from propane refrigeration cycle.
• In the solid polymeric sulfur (polymerization degree 75-80%) - fire resistant material, non-toxic, hazard class 4. Liquid sulfur is non-toxic.
• Melting point-120°C, the temperature of spontaneous combustion 575 °C.
• Solid polymeric sulfur is in the glassy state and does not generate sulfur dust.
• Liquid polymeric sulfur in the overflow and storage (in direct contact with oxygen in air) generates sulfur dioxide (SO2) in a small amount (within the maximum allowable concentration). The maximum permissible concentration (MPC) for airborne concentrations are: for sulfur dioxide - 10 mg/m3. Monitoring the MPC is the local branch of environmental control.
• Polymeric sulfur is not more toxic compounds forms in the air and waste waters in the presence of other substances and it has no cumulative properties.
