1.5. Automobile chemicals, oils and lubricants
Recently the set химикалиев, the oils and lubricants applied during performing procedures of routine maintenance and car repairs goes on sale. Here the wide range of products of the chemical and oil-extracting industry — from the cleaning structures and solvents, to oils, lubricants and aerosols for protection of rubber and plastic components of the car enters.
The cleaner for carburetors and air gates represents strong solvent of pitches, a deposit and coal deposits. The most part of cleaners for carburetors leave behind the greasing film of dry type which does not harden and does not zasmalivatsya eventually. In a type of formation of such film these cleaners are not recommended to be used for washing of electric components.
The cleaner for brake systems is applied to removal of traces of lubricant and brake fluid from surfaces of components of the brake system where absolute purity is a paramount condition of efficiency of functioning. The cleaner does not leave any marks and in many cases eliminates the squeal of brake mechanisms caused by pollution of their components.
The cleaner for electric components promotes elimination of oxide films, traces of corrosion and a deposit from contact surfaces without conductivity violation. Also it can be used for cleaning of spark plugs, jets of the carburetor, regulators of tension and other knots where full cleaning of oil and fat is desirable.
Moisture absorbers serve for removal of water and moisture from surfaces of such electric components as the generator, tension regulator, the assembly block of safety locks, electric sockets, etc. of Vlagopoglotiteli usually do not carry electric current, chemically are not aggressive and are not flammable.
Degreasers represent super-strong solvents and serve for removal of traces of lubricant from the external surfaces of the engine and components of the chassis. Are issued in the form of aerosols or are put with a brush or a brush and, depending on type, wash off or, or solvent.
RTV sealant is the most widely applied pro-masonry sealant. It is made on the basis of silicon, stiffens on air, provides sealing and good adhesion, is waterproof, fills defects of the interfaced surfaces, remains elastic, does not contract and does not sit down, it acts rather easily and applied in addition practically to all laying on knots where temperatures do not exceed average values.
Anaerobic sealant unlike RTV sealant can be applied not only in addition to laying, but also to formation of those. Remains elastic, it is steady against influence of solvents and well fills roughnesses of the interfaced surfaces. The main difference from RTV sealant consists in hardening conditions. If RTV sealant begins to stiffen at contact with air, then anaerobic sealant, on the contrary, rises only in lack of such contact. The last means that hardening of sealant happens only after assembly of components and their dense pressing to each other.
Sealant to pipes and threaded connections is applied to consolidation of nipple connections of hydraulic, pneumatic and vacuum lines. It is usually made on the basis of a teflon compound and delivered in the form of the aerosols put like paint of liquids or in the form of the film (FUM).
The anti-taking compound serves for the prevention of "prikipaniye", corrosion, jamming and cold welding of fixture. The high-temperature anti-taking sealants usually are made on the basis of cupriferous or graphite lubricants and used in fixture of system of release and a final collector.
The anaerobic taking compounds serve for prevention of a spontaneous otdavaniye of fixture as a result of vibrations and stiffen only after installation in lack of contact with air. The taking compounds of average power are applied to fixing of the small fixture (nuts, bolts, screws) which is subject to a regular otdavaniye further. High-power compounds are usually used for blocking of large fixture, need for which otdavaniye arises extremely seldom.
Additives to oil serve for correction of chemical properties of oil without change of its viscosity for the purpose of decrease in internal friction in the engine. It is necessary to notice that most the firms manufacturers producing engine oils is prevented against use of any additives to them.
Additives to fuel perform several functions, depending on the chemical composition at once. Usually contain the solvents promoting a conclusion of slags and removal of a deposit from the internal surfaces of the carburetor, components of system of injection of fuel and an inlet path. Besides, use of such additives promotes removal of the coal deposits which are formed on walls of combustion chambers. The substances serving for greasing of components of the top part of a head of cylinders (the valvate mechanism, piston rings) are a part of some additives, others promote removal of condensate from walls of the fuel tank.
Brake fluid represents specially developed structure capable to resist to influence of the high temperatures and pressure arising in a hydraulic path of the brake system. It is not necessary to allow contact of brake fluid with the painted surfaces of the car and open parts of the body. You keep brake fluid in hermetically closed container in order to avoid hit of moisture in it (liquid is very hygroscopic) and dirt.
Glue for fastening of sealing strips of body apertures as it is clear from its name, serves for fastening of sealing strips of apertures of doors, windows and covers of luggage compartments. It can be applied to fixing of elements of internal finishing.
The anticorrosive covering for the bottom of the car represents the gudronoobrazny structure prepared on an oil basis and serves for protection of metal surfaces against influence of aggressive factors of the environment. Besides, performs function of sound insulation of salon.
Wax and polish are applied to protection of a paint and varnish covering against influences of the environment. Uses of various type of vosk and polishes can demand various type of paint. The abrasive or chemical additives serving for removal of an external layer of oxides (tarnishing) from the painted surfaces of old cars are a part of some polishes. Recently different polishes which are not containing wax which part the set of chemical additives, such as polymers or substances on a silicon basis is are widely presented at the market. Such polishes are put and keep longer than usual (wax) usually easier.
