The size of the vakuum coater is too small and it is easy to produce uneven karakteristike

The atomic composition of the compound will easily produce uneven karakteristike due to its small scale. If the coating process of SiTiO3 film is unscific, the the actual surface composition is not SiTiO3, but may be other ratios. The coating film is not intended to be used. The chemical composition of the desired film, which also the technical content of vakum coating, and the specific factors are also given below.

The uniformity of the vakuum premaz stroj premaz premaz je prilično dobro

On the scale of optical film (that is, 1/10 wavelength as a unit, about 100A), the uniformity of vakum coating is faire good, and the hrapavost can be easily controlled within 1/10 of the wavelength of Visible Light, that is to say For the optical properties of the film, vakuum premaz has no prepreka, but if it resers to the uniformity on a atomic layer scale% 2c that is to say to to achieve 10A or even 1A surface flatness, the specific control factors will be explained in detail below accord to different coatings .

Vakuum premaz brtva montaža curenje

a. Whether the magnetic fluid fails;

b. Whether the connection prirubnica and the statično brtvljenje prsten in the component are oštećeno;

c. Whether the tooth profile of the pole tooth is in contact with the rotating shaft to produce dry friction;

e. Whether the permanent magnet is demagnetized, etc.

The vakuum premaz stroj treba ne inject too much magnetska tekućina

1. Pay attention to the the coaxiality requirements of the installed sealing component and the shaft, so as to ensure that the brtvljenje gap has a small ekscentričnost.

2. The injection volume of magnetic fluid should be appropriate. On the premise of ensuring that there is sufficient volume in the sealing gaps at all levels, too much magnetic fluid cannot be injected to prevent excess magnetic fluid from entering the vacuum chamber during evacuation and contaminating the vacuum chamber.

3. Before installation, the necessary vakuum čišćenje treba biti izvedeno on the components, and attention should be paid to prevent acetone, etanol and other cleaning agents from dripping into the magnetic fluid sealing components, so as to avoid the the failure of the brtvljenje komponente.
