Automobile химикалии, oils and greasings
In sale the set химикалий, oils and the greasings necessary during performance of procedures of routine maintenance and car repairs arrives. The wide spectrum 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 systems of injection and air заслонок represents strong solvent of pitches, a deposit and coal adjournment. The most part of cleaners leaves after itself greasing film of dry type which does not harden and not засмаливается eventually. In view of formation of such film the given 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 a brake liquid from surfaces of components of brake system where absolute cleanliness is a paramount condition of efficiency of functioning. The cleaner does not leave any traces иво many cases eliminates the squeal of brake mechanisms caused by pollution of their components.
The cleaner for electric components promotes elimination окисных films, traces of corrosion and a deposit from contact surfaces without infringement электропроводности. Also it can be used for cleaning of spark plugs, jets, regulators of pressure and other knots where full clearing of oil and fat is desirable.
Влагопоглотители serve for removal of water and a moisture from surfaces of such electric components as the generator, a pressure regulator, the assembly block of safety locks, electric sockets, etc. Влагопоглотители usually do not spend an electric current, do not cause corrosion and неогнеопасны.
Обезжириватели represent superstrong 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 by a brush or a brush and, depending on type, are washed off either water, or solvent.
Impellent oils represent specially developed structures for greasing of internal components of the engine. Usually contain a wide spectrum of a various sort of the additives serving for prevention of foaming and corrosion. Impellent oils are issued various degree of viscosity - from 5 to 80. Necessity of application of oil of this or that grade is usually defined by climatic conditions and requirements of the concrete engine. Liquid (easy) oils are usually applied in the conditions of a cold climate and at insignificant loadings on the engine. Heavy (viscous) oils are used in hot conditions and at the raised loadings on the engine. All-weather oils possess characteristics both easy, and heavy oils and usually have designations from 5W-20 to 20W-50.
Qualities of impellent oils
All-weather oils are rather inexpensive oils with following qualities:
All-weather oils with the improved antifrictional qualities have, besides, additional advantages:
Additives to impellent oils
It is not necessary to add any additives to the impellent oils, reducing losses on a friction.
Mixing of oils
To mix impellent oils, unfortunately, it is impossible, even if it is oils of firms «with a world name» (Shell, Mobil, British Petroleum). Each firm by manufacture of oils adds the whole complex of the additives which chemical compound is kept a secret to their basis. Therefore many the qualitative oils of identical appointment which are meeting the requirements of specifications API (Institute of oil of the USA) and ACEA (the European association of designers of cars), but the various firms made on technologies, at mixing are capable to create mixes of poor quality owing to interaction and взаимоуничтожения additives, that is their "incompatibility". Oils of different firms are interchangeable, about possibility of use of such oils developers of engines often specify. But it does not mean, that they can be mixed. Specifications API and ACEA assume obligatory identical test methods (laboratory, bench – impellent etc.) Oils of different firms. At desire (or necessities) developers can enter additional tests (or more severe constraints). The Same concerns mixing of mineral or synthetic oils (sometimes even one firm).
To mix oils foreign and a domestic production, especially what are made with the additive of "domestic" additives, it is not supposed in an extreme measure. Neither the seller, nor the consumer do not know structure of additives which are in oils. Some oils of "a domestic origin» are made by the "firms" which do not have even elementary knowledge on mineral oil. Sometimes such "experts" use the fulfilled oils (even without appropriate regeneration) to manufacture of "commodity". Thus and corresponding quality.
To try to reduce oil charcoal fumes in the old engine and to raise a compression in cylinders for use account высоковязкостных oils it is inexpedient, as it will result only in time improvement. Further engine repair will manage more expensively.
It is necessary to take for a rule to use high-quality oil of one mark corresponding to the engine (under the specification) and not to risk to mix it with same synthetic (or semisynthetic) oil. The engine will thank for it reliable work. Do not buy oil from hands as packing is easy for forging.
Трансмиссионное oil is developed for application in differentials, transmissions, and other knots where stability to influence of heats is required.
Greasing for components of the chassis and bearings of wheels represents the dense greasing applied in knots, subject to the raised loadings and a friction, such as bearings of wheels, spherical support of a suspension bracket, tips of steering draughts and карданные hinges.
High-temperature greasing for bearings of wheels is capable to resist to influence of the heats arising in bearings of wheels of cars, equipped with disk brake mechanisms. Usually it is greasing with maintenance MoS2.
White greasing (циатим) represents the dense greasing put on metal surfaces contacting among themselves in places where there are problems with the raised humidifying. Remains soft both at low, and at heats, it is not washed away and it is not diluted by water.
Assembly greasing is applied in the conditions of high pressures, usually contains molybdenum and is used for greasing of the knots subject to raised loadings (such as radical and шатунные bearings and working ledges of cams) before the first start of the engine after major repairs.
Силиконовые greasings are applied to protection of rubber, plastic, vinyl and nylon components.
Graphite greasings serve for application there where oil cannot be used in view of problems with pollution (for example, in locks). Dry graphite perfectly greases metal details, preventing influence on them of a moisture, acids and other aggressive pollution. Greasing is electrowire and does not break contact in such knots, as, for example, the ignition lock.
Молибденсодержащие getting structures are applied to simplification отдавания the "become attached" fixture, and also for greasing of fixture in order to avoid its corrosion in the future.
Теплопроводная greasing is not electrowire and serves for installation of electronic modules of ignition from which intensive heat removal is required.
Hermetic RTV is most widely applied прокладочным hermetic. It is made on the basis of silicon, stiffens on air, provides hermetic sealing, gluing, is waterproof, fills defects of 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 linings on knots where temperatures do not exceed average values.
Анаэробный hermetic, unlike hermetic RTV, can be applied not only in addition to linings, but also to formation of those. It remains elastic, is steady against influence of solvents and well fills roughnesses of surfaces. The basic difference from hermetic RTV consists in hardening conditions. If hermetic RTV starts to stiffen after hit on air анаэробный hermetic rises only in absence of air. It means, that hardening of such hermetic occurs only after assemblage of components and their dense pressing to each other.
Hermetic for pipes and carving connections is applied to hermetic sealing штуцерных connections of hydraulic, pneumatic and vacuum lines. It is usually made on the basis of teflon компаунда and it is delivered in the form of the aerosols put like a paint of liquids or in the form of a tape (ФУМ).
Antitaking компаунд serves for the prevention “прикипания”, corrosion, jamming and cold приваривания fixture. High-temperature antitaking hermetics usually are made on a basis медьсодержащих or graphite greasings and used in fixture of system of release of the fulfilled gases and a final collector.
Анаэробные taking компаунды serve for prevention spontaneous отдавания fixture under the influence of vibrations and stiffen only after installation in absence of contact to air. Taking компаунды average capacity are applied to fixing of small fixture which is subject regular отдаванию. High-power компаунды are usually used for blocking of large fixture, отдавание which it is not made on a regular basis.
Additives to oil serve for change 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, do not recommend to use any additives to them.
Additives to fuel carry out at once some functions, depending on the chemical compound. Usually contain the solvents promoting a conclusion of slags and removal of a deposit from internal surfaces and components of system of injection of fuel and an inlet path. Besides, application of such additives promotes removal of the coal adjournment formed 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 (клапанного the mechanism, piston rings), others promote removal of a condensate from walls of a fuel tank.
The brake liquid represents specially developed structure, capable to resist to influence of heats and the pressure arising in brake system. It is not necessary to suppose contact of a brake liquid to the painted surfaces of the car and open sites of a body. The brake liquid is poisonous. Hold a brake liquid in tightly closed container in order to avoid hit in it of a moisture (a liquid very much гигроскопична) and a dirt. During car operation the brake liquid takes away certain quantity of water from air that can lead to occurrence of corrosion of details of working brake system. Besides, thus the temperature of boiling of a brake liquid essentially goes down, doing by more possible formation of vials of steam at the big loading on brake system and, hence, raises probability of refusal of brakes. Therefore it is necessary to change a brake liquid of once a year. Apply the brake liquid, satisfying to car specifications.
Glue for fastening of sealing strips кузовных apertures as it is clear from its name, serves for fastening of sealing strips of apertures of doors, windows and covers of luggage spaces. It can be applied to fixing of elements of internal furnish.
The anticorrosive covering for the car bottom represents гудронообразный the structure made on an oil basis, and serves for a sheeting of metal surfaces, preventing their corrosion. Besides, carries out function of sound insulation of salon.
Воски and polyroles are applied to protection of the painted surfaces against environment influences. Use of various type восков and polyroles can demand various type of a 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 the polyroles which are not containing wax which structure includes set of chemical additives, such as polymers or substances on силиконовой are widely presented a various sort to a basis. Such polyroles usually are put and keep longer usual (wax) is easier.
