The cause of the lens coating and methods

The cause of the lens coating and methods

Lens coating, lens, or glass lenses, lamp lens are need coating appearance. Lens coating in fact, the reason is very simple, because the object has reflection effect on the light, because a lot of problems on the lens on the combination of the lens is impossible to let all light completely through various angles in theory, the light transmittance can reach more than 90%, the remaining 10% will be reflected out, form a glare. So you need to coating.
Lens coating in 1968 a new generation of coating technologies have been developed, coating process can be cheap and standard, coating lens is becoming more and more popular. Lens coating method, there are many on the market at present the most widely as one of the most popular coating method, physical vacuum coating method.
The latest way of physical coating technology, such as vacuum vapor deposition, ion plating a variety of different forms. The coating strength and uniformity generally higher than that of chemical coating. The past chemical coating, relative pollution is big, can't multilayer film plating. The latest vacuum coating to replace the chemical coating.
General coating layer on the surface of the lens itself is colorless, transparent, not only through the lens of the light will be reflected back, reflective visible to form the human eyes. Coating lens, the lens of the light transmittance is lower, reflections on the surface of the lens is more serious, therefore, each different camera lens, must according to the material used in the lens and the degree of absorption of different colours, plating on the different characteristics of the coating, mutual collocation, can increase the light transmittance of lens combined, and make the lens of light transmittance equilibrium.

Application of the coated glass is one of the most heat reflective glass and low radiation glass. Basically adopts the vacuum magnetron sputtering and chemical vapor deposition method, two kinds of production methods. Since the late eighty s, our country there have been hundreds of coated glass production factory, influential in the industry production such as vacuum magnetron sputtering method, chemical vapor deposition method
Magnetron sputtering coated glass magnetron sputtering technology can be used to design and manufacture of multilayer complex film system, can be in the white glass substrate coated with a variety of color, the membrane layer has good corrosion resistance and wear resistance, is one of the most popular product at present production and use.
Vacuum evaporation coating glass varieties and quality compared to the magnetron sputtering coating glass, there is a certain gap has been gradually replaced by vacuum sputtering. Chemical vapor deposition method is in float glass production line to the reaction gas on the surface of the glass that heat decomposition, uniformly deposited on the glass surface coated glass.
The method is characterized by less investment of equipment, easy control, product cost is low, good chemical stability, can be hot working, is one of the most promising methods of production. Making sol-gel coated glass production process is simple, the stability, the deficiencies are product high light transmittance, adornment sex is poorer.

Vacuum coating machine repair and maintenance needs Look aspects?

Vacuum coating machine repair and maintenance needs Look aspects?

User response:
1. Under normal circumstances, we need to maintain vacuum coating machine is mainly in terms of vacuum leak detection, vacuum instrument maintenance, demolition and installation to maintenance, we, the inspection step down step by step, it should be able to find the problem, when these still can not solve your machine failures, we need to turn off the power to let the machine rest, work, because the expertise to repair the vacuum coating machine is from the touch screen repair, programming, program decrypt, modify, alter and vacuum coating equipment several aspects of vacuum pump repair, vacuum heat treatment equipment maintenance and other aspects!
2. When the vacuum coating machines (vacuum coating equipment) roughing pump (plunger pumps, rotary vane pumps) continuous month (rainy season halved), to be replaced with new oil. The old oil pump is completely discharged. Tighten bolts playback oil, add new oil to the rated capacity (oil sight glass observation). More than six months of continuous use, the oil change the oil when the cover is opened, the box with a cloth to wipe clean the dirt.
Vacuum coating equipment for each completed more than 200 film programs, clean studio once. With caustic soda (NaOH) solution saturated repeated scrubbing vacuum chamber wall, (note can not directly contact with human skin caustic soda solution, in order to avoid burns) are intended to make up coating material coated aluminum (AL) react with NaOH, after the reaction the film off, and release hydrogen, then rinse with a cloth dipped in a vacuum chamber and pumping gasoline to clean fine dirt inside the valve.
Vacuum coating equipment diffusion pump continuously for 6 months or more, the pumping speed will be significantly slower, or operating properly, filling the air, remove the link pipe, remove the electric drive, will be screwed out of a nozzle, first with gasoline the pump chamber and pump bile clean again, and then wash detergent watered again, then rinse thoroughly with clean water, after water evaporation until dry, install the pump bulb, adding a new diffusion pump oil, and replace the body, take a good pipes, installed electric drive, they can re-boot. Before rebooting, pay attention to leak job. Start maintain pump, shut the door, after a few minutes to observe whether the diffusion part of the pump vacuum reaches 6X10 Pa, or to check for leaks. Check that the connection of the installed gasket, seals or crushed. After eliminating hidden leaks before heating, otherwise diffusion pump oil will burn ring, unable to enter the working state.

Vacuum coating technology advantage in where?

        

Vacuum coating technology advantage in where?

Vacuum coating technology of the most widely used in plastic products, vacuum coating factory said the plastic is easy molding, low cost, light weight, no corrosion and other characteristics, widely used plastic products, but because of its disadvantages restricted the expanded application. Through the application of vacuum coating technology, plastic surface metallization, combine organic materials and inorganic materials, greatly improved its physical and chemical properties. Vacuum coating technology advantage is mainly embodied in the following aspects:
1, make plastic surface conductivity;
2, easy to clean, no dust.
3, improve beautiful, smooth surface, the metallic color, adornment sex is greatly improved;
4, reduce water absorption, the larger the number of coating, the less pinhole, bibulous rate is lower, the product is not easy to deformation, improve the heat resistance;
5, improve surface hardness, the original plastic surface than metal soft and vulnerable, through vacuum coating technology, hardness and wear resistance increase greatly;
6, can improve the weatherability, general plastic outside can aging fast, the main reason is caused by ultraviolet irradiation, and after plating aluminum, aluminum with ultraviolet the strongest reflection, so the weather is greatly increased.

Introduction to the vacuum plating equipment common vacuum coating method

                 

  Vacuum plating equipment is used for a class of need in the vacuum coating equipment, coating method is called vacuum coating method. Vacuum coating method is in the heart of the vacuum evaporating metals, alloys or compounds (or sputtering), make them deposited on the surface of the substrate, method. On the material surface plating a layer of thin film, can be material to obtain some new chemical or physical properties. Vacuum coating method is a new coating process, also known as dry coating method, compared with the wet plating method, it has the features: 1, the film less susceptible to pollution, get good coating compactness, high purity. 2, wide range of membrane materials and the selection of base material, the film thickness can be controlled, with different vacuum plating equipment preparation of different functional thin film. 3, membrane layer and substrate adhesion, strong. 4, does not produce waste, not cause environmental pollution.
Common coating methods include vacuum evaporation, sputtering, ion plating, etc. These three coating methods have their advantages and disadvantages, including ion plating used most widely, its characteristic is: can plating materials including metals, alloys, compounds, such as membrane material evaporation method with evaporation and sputtering, membrane layer adherent strength is good, the plating film density high, uniform, can all plated surface.
