Oxidation Example

Solidification of paint on the depth of the layer occurs within a certain time and depends on the type of paint. The main types of solvents: ethyl alcohol, isopropyl and denatured (light), butanol (medium) and glycols (severe); esters – ethyl acetate (very easy), butyl acetate (Middle), ethyl acetate, glycol (heavy)-ketones – acetone (very easy), metaletilketon (easy), methyl isobutyl ketone (average), aromatic hydrocarbons – toluene (easy), xylene (middle), naphthalene solvent (Heavy) hydrocarbons – white spirit, turpentine, chlorinated solvents (trichlorethylene, perchlorethylene). ADDITIVES are chemicals that improve the properties of paints. They are added to the basic components of paint. Additives are different types:-fillers. Are powders of minerals dissolving in varnishes, and affect properties such as moisture resistance, resistance to abrasion, ease of processing by grinding. Fillers are asbestos, barytes, chalk, kaolin, mica, talc and other minerals. -Driers.

These funds are intended to accelerate the oxidation glyptal colors and are salts of organic acids – for example, salts of cobalt, lead, manganese, calcium, zirconium and zinc. In the dye is usually injected a mixture of driers. -Protivoplenochnye substance designed to protect the paint from oxidizing, packaged in cans. They increase the safety paint during storage. Inhibitors-oxidation – are volatile, so do not interfere with the action of driers in the use of paint. -Comedy.

In our time, little used. They contribute to the gloss varnish. However, their resistance decreases with time and become brittle. Natural gums are vegetable or animal origin (rosin, shellac). Synthetic gums are made up of ketone resins, etc. Methods of drying inks are related to their physical and chemical properties. Basic methods of drying two. 1. Physical drying. Is the evaporation of the solvent, resulting in a paint film. Physical drying thermoplastic acrylic are paint, cellulose paint and vinyl paint. 2. Chemical drying. Divided into types: oxidation-drying paint. Atmospheric oxygen causes oxidation of the surface of the paint film, which is due to the presence in the paint chemical agents, helps cure the resin. An example is the air-drying paint glyptal;-heat drying, is that the polymerization starts at a certain temperature. If desired temperature is reached or given a small excerpt of drying at a given temperature, the required quality paint coating is not provided. An example is acrylic paint termotverdeyuschie, epoxy-phenolic, glyptal;-polymerization using a catalyst, is that drying of resins made by polymerization, which occurs as a result of the second component – the catalyst which causes a chemical reaction. Period of use of such paints since. mixing of several hours. Examples are paint aminoplastovye with acid catalyst (hardener) epoxy-polyamide paint, polyester and polyurethane paints

As well as all other mechanisms, auxiliary parts UAZ must be in good condition, for example, to monitor the axial gap, the level of oil in the crankcase. Axial clearance of the main transfer driven gear is not allowed. His check should be made through the filler holes.

Adjustment of the gap UAZ parts rear axle must be done only when changing gears and bearings. Adjust the pinion bearings final drive through the adjustment ring and protracted nut. It should be remembered that during the formation of a large axial play drive pinion front axle can stretch into the box and lead to differential wedging of one of the leading parts UAZthe front axle. If differential for any reason, subject to demolition, then it is necessary to combine the assembly rooms, available on the left and right cups. In principle, all operations of disassembly, assembly, maintenance, adjustment and possible failure of front axle are the same as in the rear. To reduce wear and tear parts UAZ front axle, as well as for fuel economy when operating the vehicle on paved roads with off the front axle, it is advisable to disable the hub and the front wheels. Front axle service is checked regularly and lifting screw connections, checking clearances, adjusting bearings and gears mesh, toe and timely implementation of lubrication.

A number of plastic does not allow for color in mass. The reasons are different. First, you can not obtain the required decoration, for example, the intensity of color or gloss. Secondly, the introduction of a sufficiently large number of dyes leads to structural changes in the chemical nature of plastic, which negatively affects its physical properties.

Economically advantageous to carry out painting the surface of the plastic. When comparing the cost of painting in a mass of colors and in most cases because of the high cost of dyes in an advantageous position is the second option. If you plan to further stain the surface, there is no need to use expensive grade of plastic with a high and stable optical performance.
