Vacuum coating equipment ABS plastic plating common process

Vacuum coating equipment ABS plastic plating common process

Vacuum coating equipment ABS plastic plating process can be divided into three parts, this is the pre-treatment process, chemical plating and electroplating processes. Each section contains a number of processes or procedures.
(1) vacuum coating equipment ABS plastic plating pretreatment process for pre-treatment process, including surface finishing, stress checks, degreasing and coarsen...ing.

① surface finishing. ABS plastics before the treatment, to be a surface finishing, this is because in the plastic injection molding process there will be residual stress. Special gates and a portion corresponding to the gate, there will be the internal stress.

② the stress screening method. At room temperature injection molded ABS plastic release acetic immersed 2 ~ 3min, then carefully cleaned surface, dry.
③ degreasing. You can have a lot of choice in addition to oil business, after degreasing, first wash in hot water, then wash in water, and then in a 5% sulfuric acid neutralization, and then cleaned before entering the roughing process, so you can protection roughening solution so life is extended.

④ coarsening. ABS plastic roughening methods there are three types, namely high acid, high chromic acid and phosphoric acid type, from the point of view of environmental protection, it should adopt the high sulfate type.
(2) vacuum coating machine ABS plastic plating process plating process includes sensitization, activation, electroless copper or nickel plating
3) vacuum coating machine ABS plastic plating process is divided into thick plating, decorative and functional electroplating plating three.
① vacuum coating equipment thicker plating. Due to the chemical coating is very thin, make metalized plastic achieve the effect, the coating must have a certain thickness, so to thicken after plating plating.
② vacuum coating equipment decorative plating decorative plating can be a copper-nickel-chromium process, it can be bright copper then other finishing, such as brushing bronze after treatment, it can be bright nickel plated copper after adding in the light, then plated imitation gold.
③ vacuum coating equipment functional electroplating. Functional functional purpose actually depends mainly on the nature of the surface electroplated coating to be embodied. In fact, from a broad perspective, also a decorative function, but the function mentioned here, or physical or chemical means, or electrical properties. For example the conductive coating, reflective coatings, electromagnetic shielding coating, welding coating and the like.

Car paint coating merchants to introduce the benefits of the coating

Application of coating on the eyes, coating are commonly used in the camera lens, such as myopia, hyperopia, presbyopic glasses corrective lenses.
Coating is very thin, transparent film on the surface plating. The purpose is to wish to reduce the reflection of light, increase light transmittance, anti-ultraviolet radiation and minimizing down, ghost; Different colors of coating, also make different imaging color balance. In addition, the coating can be delay aging lens, color changing time.
Application in automobile, coating and beauty is the highest measures of protection of paint, can avoid oxidation, to brighten up to the paint, acid and alkali resistance, oxidation resistance, resistance to ultraviolet radiation, such as multiple functions. Because itself is a kind of inorganic membrane materials, no damage to paint.
In to the car coating, the color of its body due to aging embrittlement of paint and corrosion formation of oxide layer will go away for years. Can increase the surface hardness, avoid scratches and small aperture. Hold time is longest, about more than a year.
Coating is not perfect, the brightness is inferior to seal glair when finished plating membrane, therefore is not suitable for love beautiful juyou, vehicle coating price in one thousand yuan of above.
The principle of coating, the coating is mainly in order to reduce the reflection. In order to improve the light transmittance of lens and the quality of the image, in the modern lens to the lens coating manufacturing process. Lens coating is according to the principle of optical interference, on the lens surface plating layer thickness of about a quarter wavelength of the material (usually a fluoride), make the lens to the wavelength of light reflection to a minimum. Obviously, a membrane only work on a light, and multi-layer coating can work on a variety of colours. Multilayer coating with different materials usually repeatedly on lens surface plating layer with different thickness. Multilayer coating can greatly improve the light transmittance of the lens, for example, without coating on the surface of the lens every reflectivity of 5%, after the single layer coating down to 2%, and the multi-layer coating can be down to 0.2%, in this way, can greatly reduce the diffuse reflection between each camera lens, so as to improve the contrast of image and Octavia degrees.

Third, the main factors affecting the level of vacuum insulation

Vacuum insulation is a very complex physical process and the mechanism is so far no clear conclusion. From a practical point of view, mainly in the following aspects:

1, the geometry of the electrodes

Geometry of the electrodes has a great influence on the distribution of the electric field, are often not appropriate due to the geometry, causing localized excessive concentration of the electric field caused by the breakdown, which is particularly prominent in the high voltage vacuum products.

Radius of curvature of the edges of the electrodes is an important factor. In general, large radius of curvature the capacity electrode is smaller than the breakdown voltage of the large radius of curvature.

In addition, the breakdown voltage is also inversely proportional to the electrode area, and that with the increase of the electrode area is reduced. The main area is increased resulting in a reduced withstand voltage because the discharge probability increases.

2, the gap distance

Vacuum breakdown voltage and the gap distance has a relatively clear relationship. Tests showed that when the gap distance is small (≤5mm), the breakdown voltage of the gap distance increases linearly increase, but with the further increase in the gap distance, the breakdown voltage of the slowdown, i.e. vacuum gap breakdown electric field strength increases gap distance decreases. When the gap reached a certain length (≥20mm), increasing the gap distance alone raise the pressure level has been very difficult, but this time using more favorable than single fracture fracture.

Generally believed that electrical short gap breakdown under field emission is mainly caused by the long gap between the lower and the electrical breakdown of the particle effects are mainly due.

3, the electrode material

Vacuum switches operate in a high vacuum over 10-2Pa, because this time is very rare gas molecules, gas molecules collide against the free breakdown has no effect, so the breakdown voltage and electrode materials exhibit a strong correlation.

Breakdown voltage of the vacuum gap varies with different electrode materials, the researchers found that the breakdown voltage and the hardness and mechanical strength of the material. In general, the hardness and high mechanical strength material, tend to have a higher dielectric strength. For example, steel electrodes hardness after quenching, before hardening than the breakdown voltage can be increased by 80%.

In addition, the breakdown voltage and also a cathode material physical constants such as melting point, specific heat and density are related, i.e., a material whose melting point higher breakdown voltage is higher. Specific heat and density in terms versa. The essence of the problem is in the same action of thermal energy, the greater the probability of occurrence of the molten material, the lower the breakdown voltage.

4, the degree of vacuum

Figure 1 shows the relationship between the breakdown voltage and the gas pressure in the gap between. Can be seen from FIG vacuum higher than 10-2Pa (10-4 Torr), the breakdown voltage is substantially longer with decreasing gas pressure increases, the gas molecules collide because the phenomenon is no longer free to function. When the gas pressure is gradually increased from l0-2Pa (vacuum reduction), the breakdown strength is gradually decreased, while close to 1 Torr (approximately 102Pa) minimum, and later with increased pressure and increased. As can be seen from the curve when the degree of vacuum higher than 10-2Pa its compressive strength is substantially unchanged. This indicates that the degree of vacuum interrupter when 10-2Pa more fully able to meet the needs of normal use.

5, the electrode surface condition

Condition of the electrode surface breakdown voltage greater impact on the vacuum gap. Oxide electrode surface, impurities and metal particles will cause the breakdown voltage of the vacuum gap decreased.

In addition, regardless of the electrode surface in a vacuum interrupter manufacturing process was how large current breaking will involve electrode surface becomes uneven, which will also make the breakdown voltage decreases.

6. Aging effect

Aging electrode voltage and current Burn Burn two kinds.

When a new test vacuum gap, the breakdown voltage tends to lower the first few times. With the increase of the number of trials of the breakdown voltage is gradually increased, eventually stabilize at a certain value. This breakdown voltage with frequency increasing breakdown voltage phenomenon is the role of the old mill.

Aging is the voltage on the electrode surface by microscopic projections discharge elimination of impurities and defects. So that a small current through the discharge point of the surface of microscopic projections seizure, evaporation, smooth surface of the electrode, a local electric field enhancement effect is reduced, improving the breakdown voltage. Aging purification effect on the electrode surface is also very important. Since the electron emission electrode surface prone to lower the work function of the place where the impurities, also makes the discharge breakdown melting and volatile impurities, can also increase the breakdown voltage of the gap. Aging process, if at the same time the vacuum pump pumping, the evaporating gaseous substance pumped, the better. Aging voltage only suitable for use in a vacuum gap breakdown voltage increase, the vacuum interrupter contacts gap breakdown voltage increase will not have much effect. Arc on the contact surface of the burning effect will make the voltage experienced all fail.
