Chemical plating is a process called chrome plating. It is based on the reaction of the silver mirror. This effect allows to achieve the shiny coating on the surface of the product.
Modern technology of chemical plating can be used to develop spray special coating materials and reagents. As a result, the finish will glisten and reflect the surrounding objects. In addition, the chemical plating allows to achieve the highest degree of adhesion.
It is Important that the coating process is carried out without the aid of any corrosive substance or explosive components. Carcinogenic components of chromium are reduced to an absolute minimum. Chemical metallization is not restricted by the shape and size of the product. Also not required to place a subject in a liquid acid medium or to resort to a strong heat.Surface Preparation for plating is similar to the process before applying the paint. The mirror coating can cover any bases, but they were metal. Such chemical treatment does not require significant cash injections. Enough to buy special equipment and reagents.
In the end, the owner of the equipment will be able to apply “silver mirror" even on porous or organic materials. No other technology will not be able to give similar results. Today chrome plating is a strong competition to other metallization processes.
The First step for chemical plating is applied on the surface of the binder soil. For this fit the standard spray paint. First, on the surface 2-3 of the binder layer of the soil. It is desirable that it was SN.305. In the case of a porous product layers can be a little more.
After obtaining a vitreous coating, with effect of gloss, please allow the product to dry. In the end, the bonding primer will provide the subject of good adhesion, high rate of pollination and perfect mirror Shine.
For the second phase of the technology will require the installation of “Meta-Khrom”, which will be carried out chemical plating. For starters, the surface is activated by spraying a reagent on it ST.2516. Subsequently, the product must be carefully rinsed with distilled water. Then the surface is sprayed modifier "Meta-Khrom” and reagents-recovery of AV series 101 and 202. Thanks to them, formed the white metal coating, like a mirror.At the final stage, you need to protect the result of chroming. It uses a special installation, spray varnish. For optimum protection against wear and tarnishing it is best to apply several layers. In the mixture of protective varnish can add color pigments to the surface has acquired the desired shade. So the effect of chromium, gold, bronze, copper and other metals.

Plating chemical – this is a very simple process. To apply the coating is technologically easy. It's enough to have standard nozzles. This allows to apply the coating on any of the products from the body of the phone to the car hood or statues. Chrome plating can be affected by any material: plastic, ceramic, wood, gypsum and so on. The reflectivity of the coating depends on the number of layers applied.
Plating chemical gives the product additional strength and firmness. Moreover, the coating has high wear resistance. For the strength meets the protective lacquer, which is able to withstand any operational wear.
The process of chrome plating dimensions are irrelevant. The coating may be any surface area in a short time. This is one of the main differences from the vacuum metallization process or a galvanic electrodeposition. Chemical coating is much cheaper than using other methods. Average savings is up to 30%. In addition, the coating is environmentally friendly. In the same electroplating process, the plating occurs with the use of toxic hexavalent components.
In chrome plating, you can choose any color of the coating. It's enough to add to the composition of the protective varnish a little toner.
Chrome plating can be performed independently. You will need a small non-residential premises, protected from moisture and dust, and a special installation carrying out the process of chemical metallization.
The first step is to prepare the workplace and to clean away dirt, rust, paint. Applying a bonding primer to the surface to produce better conventional spray gun. This will allow to obtain a perfectly smooth glassy coating. To dry the product can be in the sun or under a lamp, the main thing that it is not contaminated. The plating Process is very hard. This will require a setup that will spray the product specialchemicals. As a result of reaction with the binder soil is reached white mirror coating. To protect against tarnishing and wear should be sprayed on the surface of a special lacquer. It will also fit a standard spray gun.
On average, the whole process of chemical plating at home takes about 17-18 hours.
Add to chrome in the first place should meet the main principles of performance. Equipment for chemical metallization should have at least two pressure vessels with the reagents. Their total volume – 12 liters. This will greatly extend the process.
For beginners it is important to informativeness, so the installation needs to be signed by all the buttons. It is important that on the front panel all the gauges were in the immediate vicinity of the pressure regulators.
Equipment for chemical metallization should meet ergonomics. The presence of the filler in the installation allows the dynamics to quickly add reagents in the tanks as needed. The main requirement to the manifold is a check valve. Thanks to him, the reagents will not mix. High reliability of the equipment is high quality control. So the installation must belong to one of the world's leading brands. If the warranty period is less than three years, so do not waste your money for nothing.
As the process of chemical plating is harmless, and the equipment itself should be environmentally friendly. It is important that tanks are not leaking reagents. In expensive installations, an automatic air filtration. In such nozzles the compressor cleans particulates from lubricants and oils.
The Most common setting for chemical metallization – “Meta-chrome/Pro-1». Its distinctive features are the built-in display temperature in subsystems, one-stage air filtration, manifold with valve reverse thrust, the design of the containment tanks, increased pneumostar for supplying pressure to the gun.
This is a very compact camera, the package includes the gun, a set of reagents for a 20 sq. m, a box for reagents, toners and a telemetry instrument. The cost of this installation is about 120 thousand rubles.Apparatus "Meta-chrome/Pro-2” is an improved version of Pro-1. From additional features there is an indication of the conductivity of the liquid in the tank, two-stage filter and built-in drain valves. The kit includes 2 spray chemicals on 60 square meters, a container for reagents, 6 toners and conductivity. The cost of this installation – about 140 thousand rubles.
All reagents for chemical metallization should be prepared with specially filtered water. This achieves high light fastness and minimum coating thickness (up to 0.4 MK). It is important that the solution was the maximum concentration of the reagent. Reagents for chemical metallization should not contain the carcinogens and irritants to the respiratory system.
Kit 20 sq. m should contain reagents in the following amounts: binder, soil – 3.3 l, protective lacquer – 1.6 l, modifier – 1 litre activator – 1 l, reducing agent – 1 l, hardener – 0.5 l, pigment toners – 40 ml. the Price of this will be about 20 thousand rubles.
Often in wide production over individual reagents for chemical metallization. Therefore, it is important to take care of buying a spare set of necessary substances. However, there is a cheaper option – the retail purchase of reagents. Currently available for sale, you can find the reagents for the chemical metallization according to the following indicative prices (ratio to 1 liter of fluid): binder primer – 1500 RUB, protective lacquer – 1450 RUB, restorer – 1350 RUB, stabilizer – 1200 RUB, activator – 900 RUB, hardener – 700 rubles. the Most expensive is the modifier – 7300 rubles. per liter.
Numerous studies have shown that the coating applied by chemical plating, able to withstand the shock impact of about 55 kg/cm2 without any traces. In addition, particles of chromium does not remain on the sticky tape. Also, the coating was successfully tested on the effects of salt spray. Thus, it is completely protected from corrosion and clouding.
