1.5. Automobile himikaliya, oils and greasings
Recently in sale the set химикалиев, oils and the greasings applied during performance of procedures of routine maintenance and car repairs arrives. The wide range of products of the chemical and oil-extracting industry — from cleaning structures and solvents, to oils, greasings and aerosols for protection of rubber and plastic components of the car here enters.
The cleaner for carburetors and air a zaslonok represents strong solvent of pitches, a deposit and coal deposits. The most part of cleaners for carburetors leave after itself greasing film of dry type which does not harden and not засмаливается 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 greasing and brake liquid from surfaces of components of brake system where absolute purity is a paramount condition of efficiency of functioning. The cleaner does not leave any traces 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, corrosion and deposit traces from contact surfaces without elektroprovodnost violation. Also it can be used for cleaning of spark plugs, jets of the carburetor, regulators of tension and other knots where complete cleaning of oil and fat is desirable.
To Vlagopoglotiteli serve for water and moisture removal from surfaces of such electric components as the generator, a tension regulator, the assembly block of safety locks, electric sockets, etc. Vlagopoglotiteli usually do not carry out an electric current, chemically are not aggressive and are not inflammable.
Obezzhirivateli is represented by super-strong solvents and serve for removal of traces of greasing from external surfaces of the engine and chassis components. Are issued in the form of aerosols or are put with a brush or a brush and, depending on type, are washed away either water, or solvent.
RTV hermetic is most widely applied prokladochny hermetic. It is made on the basis of silicon, stiffens on air, provides sealing and good adhesion, is waterproof, fills defects of interfaced surfaces, remains elastic, it is not compressed and does not sit down, it acts rather easily in film and applied in addition practically to all laying on knots where temperatures do not exceed average values.
Anaerobny hermetic unlike RTV hermetic 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 interfaced surfaces. The main difference from RTV hermetic consists in hardening conditions. If RTV hermetic starts to stiffen at contact to air, anaerobny hermetic, on the contrary, rises only in absence of such contact. The last means that hardening of hermetic occurs only after assembly of components and their dense pressing to each other.
Hermetic for pipes and carving connections is applied to consolidation of shtutserny connections of hydraulic, pneumatic and vacuum lines. It is usually made on the basis of a teflon compound and it is delivered in the form of the aerosols put like paint of liquids, or in the form of a tape (FUM).
The anti-taking compound serves for the prevention of "prikipaniye", corrosion, jamming and cold welding of fixture. High-temperature anti-taking hermetics usually are made on the basis of medsoderzhashchy or graphite greasings and used in fixture of system of release and a final collector.
Taking compounds serve Anaerobnye for prevention of a spontaneous otdavaniye of fixture under the influence of vibrations and stiffen only after installation in absence of contact to air. Taking compounds of average capacity are applied to fixing of small fixture (nuts, bolts, screws), 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 an internal friction in the engine. It is necessary to notice that the majority of the firms manufacturers which are letting out engine oils, warn against use of any additives to them.
Additives to fuel carry out at once some functions, depending on the chemical composition. Usually contain the solvents promoting a conclusion of slags and removal of a deposit from internal surfaces of the carburetor, components of system of injection of fuel and an inlet path. Besides, application of such additives promotes removal of the coal deposits which are forming on walls of chambers of combustion. The structure of some additives includes the substances serving for greasing of components of the top part of a head of cylinders (the klapanny mechanism, piston rings), others promote condensate removal from walls of a fuel tank.
Brake liquid represents specially developed structure, capable to resist to influence of high temperatures and the pressure arising in a hydraulic path of brake system. It is not necessary to allow contact of brake liquid to the painted surfaces of the car and open sites of a body. Keep brake liquid in tightly closed container in order to avoid moisture hit 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 furnish.
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 environment. Besides, carries out function of sound insulation of salon.
Wax and polyrole are applied to protection of a paint and varnish covering against environment influences. Use of various type восков and polyroles can demand various type of paint. The structure of some polyroles includes the abrasive or chemical additives serving for removal of an external layer of oxides (tarnishing) from painted surfaces of old cars. Recently in the market polyroles not containing wax which structure includes a set of chemical additives, such as polymers or substances on a silicon basis are widely presented different. Such polyroles usually are put and keep more long than usual (wax) easier.
