A Adhesion - (from Latin adhaesio - adhesion) in physics - the adhesion of the surfaces of dissimilar solid and / or liquid bodies in places where their surfaces come into contact. Adhesion is caused by intermolecular interaction in the surface layer and is characterized by the specific work needed to separate the surfaces. In some cases, adhesion may be stronger than cohesion, i.e., adhesion within a homogeneous material, in such cases, when a bursting force is applied, a cohesive break occurs, i.e., a gap in the volume of the less durable material in contact. Adhesion significantly affects the nature of friction of contacting surfaces: for example, friction of surfaces with low adhesion friction is minimal. An example is polytetrafluoroethylene (Teflon), which, due to the low adhesion value in combination with most materials, has a low coefficient of friction. Some substances with a layered crystal lattice (graphite, disulphide-molybdenum), characterized simultaneously by low values ​​of adhesion and cohesion, are used as solid lubricants. The most well-known adhesion effects are capillarity, wettability / non-wetting, surface tension, meniscus of liquid in a narrow capillary, friction of two absolutely smooth surfaces. The adhesion criterion in some cases can be the time of detachment of a layer of material of a certain size from another material in a laminar flow of liquid. Adhesion takes place in the processes of gluing, soldering, welding, coating. Adhesion of the matrix and filler of composites (composite materials) is also one of the most important factors affecting their strength.

Additive   - a component that gives polymers the necessary properties.

Acrylic   - the colloquial name of polymers based on derivatives of acrylic and methacrylic acids and polymer compositions from them. Since acrylic is easy to clean, resistant to household acids and solvents, bacteria do not multiply on it, it is most often used for the production of sanitary ware, paints, sealants, and also kitchen countertops, sinks and aprons.

Antioxidants   - substances that increase the resistance of polymers to the action of oxygen.

Antiseptic(lat anti - against, septicus - decay) - a system of measures aimed at the destruction of microorganisms in the wound, pathological focus, organs and tissues, as well as in the body of the patient as a whole, using mechanical and physical methods of action, active chemicals and biological factors .

AT Moisture recovery   - property of the material to lose the water that is in its pores.

Moisture resistance   - property of the material to provide long-term resistance to the destructive effect of moisture during periodic moistening and drying.

Humidity   - the ratio of the mass of water currently in the material to the mass of the material in the dry state.

Water resistant   - (W) - the ability of concrete not to pass through water under pressure. For example, W20 means that the concrete retains water pressure of 20 atm (2.0 MPa).

Water absorption- the property of the material in direct contact with water soak and retain it in its pores.

Water permeability- the property of the material to pass water under pressure.

Water retention ability- the ability of the solution mixture to retain excess water. The water-retaining capacity protects the solution from loss of large water quality when applied to a porous substrate, as well as from delamination during storage and transport.

Time…   Time to achieve full strength - the time for which the material is gaining full strength according to the characteristics of the binder. Time adjustment - the time during which the material retains ductility. Setting time - the period during which the mixture is used (plaster, putty, glue, etc.) acquires strength. The hardening time is the time through which the material loses its plasticity.

D Sealing   - ensuring the tightness of the walls and joints that limit the internal volumes of apparatuses, machines, structures. Applied in various fields of science and technology. The methods are selected depending on the specific conditions. Widely used soldering and welding joints, gas-tight cast parts, special vacuum materials, sealing compounds, seals.

Sealantsis a pasty or viscous flow composition based on polymers or oligomers that are applied to joints and joints of structural elements of buildings and structures to prevent leakage of the working medium through the design gaps and for waterproofing. The sealing layer is formed directly on the joint seam as a result of curing (vulcanization) polymer backbone   or evaporation of the solvent; There are also sealants, which, after application to the sealing surface, do not undergo any changes (low-lying putty). Acrylic Sealants -   sealants, the main component of which is acrylic. Acrylic is a colloquial name for polymers based on acrylic acid derivatives or materials from them. Effective when filling cracks and seams in concrete products. These sealants are perfectly covered with paints and varnishes, withstand a slight vibration. Minus of use - low resistance to atmospheric phenomena and moisture. Sealants on acrylic base do not contain solvents in their composition. Acrylic sealants have good adhesion (in the people - adhesion) to concrete, brickwork, wood, plaster, etc. Do not stand deformation. The cheapest of modern building sealants - acrylic, as a rule, are not designed for outdoor works. The reason is that acrylic mastics are not elastic, but plastic - they are well applied, but do not withstand mechanical loads and temperature changes. The field of application of acrylic sealants is not the responsible parts of internal sealing. Bituminous Sealants   - sealants based on bitumen. They do not dissolve in water, they dissolve completely or partially in benzene, hydrogen sulfide, chloroform and other organic solvents. They have good adhesion to a wide range of substrates (concrete, bitumen, wood, metal, plastic). They are applied to wet substrates. Operated at low temperatures. The main application area is the filling of cracks in the roof, base, foundation, etc. Butyl Sealants   - a sealant based on butyl - a monovalent radical of butane (C4H9). They are mainly used for manufacturing insulating glass. They have excellent adhesion to glass, aluminum and galvanized steel. Do not contain solvents. They are vapor-permeable, which is very important for the production of insulating glass. Have low strength at low temperatures. They have high resistance to UV radiation. The disadvantages of this sealant can be attributed to its color - only black, and application only in one sphere. Polyurethane Sealants- Sealants based on polyurethane - a synthetic elastomer (highly elastic polymer) with programmable properties. Used for sealing and gluing various types of materials - plastic, glass, paving stones, concrete, metal, ceramics. There are one-component and two-component. Polyurethane sealants are universal, durable and elastic, do not shrink when vulcanized. Stick to any material, and work with them is possible in all weather conditions. Inter-panel joints on polyurethane sealant are durable and of high quality. Polyurethanes do not shrink when vulcanized, so you can accurately calculate the consumption of the sealant. Polyurethane sealants are durable and elastic, able to withstand long regular deformations and restore their shape. Silicone Sealants   are low molecular weight silicone rubbers (silicone polymer, usually dimethylpolysiloxane with terminal hydroxyl groups). The composition may include various fillers that make the sealant flame-retardant, heat-resistant. They also improve adhesion to various building materials. They are used for outdoor and internal works. Some of the most durable due to their high resistance to different temperatures, mechanical stress and ultraviolet, however, have several significant drawbacks, they have good adhesion only to a strictly defined amount of materials, are not applied to wet substrates, have a sufficiently long hardening time - especially at low temperatures and humidity, do not stain. Thiokol (Polysulfide)- sealants based on liquid polysulphide rubbers (thiokols) - artificial rubbers made using polysulphide - a multi-sulfur compound. Widely used in shipbuilding, aircraft building, radio electronics, electrical engineering and civil engineering, for example, for sealing inter-panel joints. Completely vulcanized after 10 days. These sealants are less durable than silicone sealants and weakly resist deformations (no more than 25%). The disadvantages of thiocoline sealers include low thixotropy - the seams closed by thiokal sealants gradually "creep", on the facade the seam looks wide, uneven. Stitches treated with thiocal sealant, turn black with time. They can be applied only at a temperature above -10 ° C and can not be applied to a wet surface, respectively, the application mode is strongly tied to weather conditions. MS-polymersealantsare sealants based on modified silicone. They have the advantages of both silicone and polyurethane. Excellent adhesion to almost all materials: metal, wood, plastic, glass, ceramic tiles, concrete, natural stone. Elastic and elastic. High heat resistance. Resistant to weather and weather conditions. Adhesion to wet substrates. Dust- and dirt repellency. We paint.

Hydration - (from the Greek hydro - water) - the attachment of water molecules to molecules or ions. Hydration is a special case of solvation - the addition of molecules of an organic solvent to molecules or ions. Unlike hydrolysis, hydration is not accompanied by the formation of hydrogen or hydroxyl ions. Hydration in aqueous solutions leads to the formation of persistent and unstable compounds of water with a dissolved substance (hydrates); in organic solvents similar solvates are formed to hydrates. Hydration causes the stability of ions in solutions and makes it difficult to associate them. Hydration is the driving force of electrolytic dissociation - a source of energy needed to separate oppositely charged ions.

D Deformability   This is an indicator established by an independent expert body, which determines the retention of the sealant elasticity under statistical deformations by this value. An accredited laboratory, having tested a seam with a sealant at a certain statistical deformation producer, establishes a predicted service life in the following way: 1) the deformation information is correct only together with the data on the service life; 2) the manufacturer must confirm this documentation (acts, protocols). Example: a sealant with a deformability of 50% and a predicted service life of 8 years is probably better than a sealant with a deformability of 25% and a predicted lifetime of 10 years.

A rectangular triangle with a 3: 4: 5 aspect ratio. The sum of these numbers (3 + 4 + 5 = 12) has been used since ancient times as a unit of multiplicity for the construction of right angles with the help of a rope, marked by knots on 3/12 and 7/12 of its length. It was used in the architecture of the Middle Ages to build proportionality schemes.
