chemical metallization is a process referred to as chrome plating.It is based on the reaction of silver mirror.This effect makes it possible to achieve brilliant coating on the surface of the product.
Basics chroming
Modern technology allows the use of chemical metallization for the development of a special paint spraying materials and reagents.As a result, coverage will be shine and reflect the surrounding objects.In addition, it allows for the chemical plating the highest degree of adhesion.
It is important that the coating process is carried out without the aid of any corrosive substances or hazardous components.The carcinogenic components of chrome plating are reduced to an absolute minimum.Chemical metallization has no restrictions on the shape and size of the product.It is also not required to put the subject in a liquid acidic environment or resort to strong nagrevu.Podgotovka surface similar to the chrome plating process before applying the paint.With this mirror coatings may cover any bases, but rather that they were metal.Such chemical treatment does not require significant cash injections.It suffices to acquire special installation and reagents.
As a result, the owner of the equipment will be able to apply the "silver mirror" even on porous or organic materials.No other technology can not produce the same results.Today, chrome is strong competition other metallization processes.
main stages of technology
The first step will be to chemical metallization coating the surface of the soil binder.For this fit the standard paint sprayer.First applied to the surface of the binder layer of soil 2-3.It is desirable that this was the SN.305.In the case of a porous product layers may be little more.
After receiving a glassy gloss coating effect is necessary to give the product to dry.As a result, the bonding primer will ensure good adhesion of the subject, a high rate of pollination and perfect luster.
For the second phase of the technology need to install "meta-chrome", thanks to which will be carried out and plating chemicals.To begin the surface is activated by sputtering at her reagent ST.2516.Thereafter, the product must be thoroughly rinsed with distilled water.Then, the surface is sprayed modifier "meta-chrome" and reducing agent AB Series 101 and 202. Thanks to them, formed a snow-white metallic coating, similar to zerkalo.Na final stage of chrome plating to protect.It uses special plant, spray varnish.For optimum protection against wear and tarnishing is best to apply several layers.The mixture of protective lacquer can add pigments to the surface found the desired shade.This is because an effect of chromium, gold, bronze, copper and other metals.
Advantages
Metallization chemical - it is a very simple process.Apply coating technology is simple.It's enough to have a standard spray.This allows you to apply a coating to any product from the phone to the car body hood or statue.Chrome plating may be exposed to any material: plastic, ceramic, wood, plaster, and so on.The degree of reflection depends on the number of coating layers applied.
chemical metallization gives the product extra strength and hardness.Moreover, the coating has high wear resistance.For strength here corresponds to a protective varnish, which is able to withstand any operational wear.
for chroming process size does not matter.May undergo any deposition surface area in a short time.This is one of the main differences from the vacuum metallization process or galvanic plating.The chemical coating is much cheaper than using other methods.Average savings of up to 30%.Moreover, the coating obtained clean.In the same galvanic plating process occurs using toxic hexavalent components.
When plating can choose any color coating.It is enough to add to the composition of the protective lacquer little toner.
chemical metallization with their hands
Chrome can be made independently.This will require a small non-residential premises protected from moisture and dust, and a special unit carrying out the process of chemical metallization.
In the first step should be to prepare a working place and clean the product from dirt, rust, paint.Application of the binder to the surface of the soil is better to produce a conventional spray gun.This will get a perfectly smooth vitreous coating.The product can be dried in the sun or under a lamp, as long as it is not contaminated.Metallization process is the most complex.This will require the installation, which will spray the product specific chemicals.The reaction with the binder soil is reached snowy mirror coating.To protect against tarnishing and wear should be sprayed onto the surface of a special lacquer.It also fit a standard gun.
On average, the whole process of chemical chromium plating at home takes about 17-18 hours.
Hardware Requirements
plant for chroming must first meet the main principles of performance.Equipment for chemical metallization must have at least two pressure vessels with the reagents.Summary of volume - 12 liters.This will greatly extend the process.
For beginners important aspect is informative, so in a facility should be signed by all the buttons.It is important that the front panel gauges were all in close proximity to the pressure regulators.
equipment for chemical metallization should meet ergonomics.The presence of fillers in the installation allows you to quickly add to the dynamics of the reactants into the tanks as needed.The main requirement is to a manifold check valve.Thanks to him, the reagents are not mixed.High reliability is achieved by high quality control.The installation must necessarily belong to one of the world's leading brands.If the warranty period is less than three years, so do not waste money.
Since the chemical chromium plating process is harmless, and the equipment itself needs to be environmentally friendly.It is important that the tanks are not leaking from the reactants.The expensive installations has an automatic air filtration.In such dispensers compressor clears microparticles of grease and oils.
Specialty
most common setting for chemical metallization - a "meta-chrome / Pro-1."Its distinctive features are built-in temperature display subsystems, single-stage air filtration, valve manifold with reverse thrust, the construction of decompression tanks, increased pneumatic hose for supplying pressure to the gun.
This is a very compact device, which includes a complete set in the gun, a set of reagents on the 20 square meters.m, kit reagents, toners and telemetry conductivity.The cost of such an installation is about 120 thousand rubley.Apparat "meta-chrome / Pro-2" is an improved version of the Pro-1.Among the additional features it has a display of conductivity of the liquid in the tank, a two-stage filter and a built-in drain valves.The set includes 2 gun, reagents for 60 square meters.m, container reagents 6 toners and conductivity.The cost of this facility - about 140 thousand rubles.
Main reagents
All reagents for chemical metallization should be cooked in a specially filtered water.This achieves a high light fastness and the minimum coating thickness (0.4 microns).It is important that the solution had a maximum concentration of the reagent.Reagents for chemical metallization should not contain carcinogens and substances that irritate the respiratory tract.
set at 20 square meters.m should contain reagents in the following volume: binder ground - 3.3 liters, protective varnish - 1.6 l modifier - 1 liter activator - 1 liter, the reducing agent - 1 liter hardener - 0.5 liters, pigment toners - 40ml.The cost of such a set will be about 20 thousand rubles.
additional reagents
often end with the production of a wide individual reagents for chemical metallization.It is therefore important to take care of buying a spare set of necessary substances.However, there is a cheaper option - the purchase of retail reagents.Currently, commercially available reagents can be found for chemical metallization of the following indicative prices (at the ratio of 1 liter of liquid): bonding primer - 1500 rubles., Protective varnish - 1450 rubles., A reducing - 1350 rubles., Stabilizer - 1200 rubles.Activator - 900 rubles., hardener - 700 rubles.The most expensive is considered a modifier - 7300 rubles.per liter.
test data
Numerous studies have shown that the coating applied by chemical plating is able to withstand the impact force of 55 kg / cm2 without any traces.Moreover, the particles do not remain on the chromium plating adhesive tape.Also, the coating has been tested for salt spray exposure.Thus, it is completely protected from corrosion and turbidity.
