Glass coating, vacuum coating machine coating Notes

Automotive glass coating increasingly popular, but many people enjoy the convenience of just after the glass coating, maintenance coating film after the relevant considerations and has not been done, this effect is maintained for the coating is very unfavorable.

First, vacuum coating machine glass coating can be applied over the rearview mirror.

Because the mirror is not the wind, if the plating to allocate water glass drops then there will accumulate, thus affecting sight. Advanced car mirrors are hydrophilic glass. In fact, the general construction glass coating only the front windshield glass and other glass mirrors can also be construction but it is absolutely not the construction.

Second, anti-fog construction do not apply too thick.

Glass and glass coating agents typically used in conjunction with anti-fog, anti-fogging agent in glass at the time to pay attention not to apply too thick, too thick smear if they would not wipe clean. In addition, the duration of the anti-fogging agent with the weather, dry weather often duration, continuous rainy weather, then anti-fog effect is relatively short period of time, it is also important to note.

Third, posted proof membrane can still be coated.

Utility proof membrane is insulated privacy glass coating function is to increase the splash of the glass, these are two entirely different things, I do not know why anyone would think that the film will not be posted proof coating of. In fact, this is wrong, there is no proof membrane and coating affected. Proof membrane is usually attached to the glass inside, and coating agents and anti-fogging agent is generally used on the outside.

Fourth, do not rain or washing within four hours after the glass coating.

This is in order to better protect the car glass coating effect, rain or washing may affect the duration of the coating. And when coated glass has been cleaned, the coating process and will not stain the body, there is no need to wash after the film is completed. To avoid the rain, then simply choose the good weather to do a film on it.

Coated Glass (Reflective glass), also known as reflective glass. Coated glass is coated one or more layers of metal, alloy or metal compound film on the glass surface, to alter the optical properties of the glass, to meet certain requirements. Coated glass according to the different characteristics of the product, can be divided into the following categories: heat-reflective glass, Low-E glass, Low-E, conductive film glass.
Heat-reflective glass is usually coated on the glass surface layer or layers of thin films, such as chromium, titanium or stainless steel and other metals or compounds consisting of the product showed a rich color, appropriate for visible light transmittance, infrared has higher reflectance, the coated glass has a higher UV absorption rate, therefore, also known as solar control glass, mainly for building and glass curtain wall;
Low-E glass is coated on the glass surface of a multilayer thin-film of silver, copper or tin, or a compound consisting of a metal, the product has a high visible light transmittance, high infrared reflectivity, a good heat insulation performance, mainly used in construction and automotive, ships, and other transportation, due to poor film strength, are generally made using hollow glass; glass conductive film is a conductive film of indium tin oxide coated glass surface, etc., can be used for heating the glass defrost, defog and as liquid crystal displays..
Many coated glass production methods, the main vacuum magnetron sputtering, vacuum evaporation, chemical vapor deposition and sol - gel method. Magnetron sputter coated glass by magnetron sputtering techniques can be designed for producing a multilayer complex film system, a variety of colors can be coated on a white glass substrate, the film is preferably corrosion and wear resistance, is the production and use one of the largest product.

Watch glass coating and precautions

Watch glass coating and precautions

Any glass will have a reflective, including flat and have a curved glass, so, like many lens optical instruments (including glasses), the increase in order to reduce reflection and transmission ratio, you need to vacuum coating equipment to do the above in the glass coating processing. Especially glass diameter compare Japanese radian watches, need to increase the coating processing, can not completely eliminate the reflective coating, can only be reduced.

In the optical film material is currently available, a magnesium fluoride (MgF2) of refractive index of about the minimum, only 1.38, the magnesium fluoride coating can make use of light reflection rate of 4% to 1.8% while also increasing the transmission than, of course, in order to improve the transmission rate, it can also be used for multi-layer antireflection coating that both sides are coated inside and outside of the glass.

After the glass coating process above, will be showing a hint of violet color, typical is a camera or telescope lens, are usually treated with magnesium fluoride coating (MgF2), the refractive index of magnesium fluoride is 1.38, both much lower than the refractive index of ordinary glass, even lower than the sapphire glass (ordinary glass refractive index of 1.52, sapphire 1.76), where the higher the refractive index, the reflection is stronger. Therefore, the effect of the watch sapphire glass coating will be better after.

Some watches will create a flag to indicate that the watch glass is processed through the coating, such as Omega watches, the watch on the card or tag, with a circle inside a A letter to represent, while the AA said watch both inside and outside the glass coating on both sides. Originally reflex points on the watch, the more, including the case, dial, hands, not Guangcan gold, silver Guangcan is, therefore, the coating is more convenient to use one of the measures to wear watches, watch glass coating also does not like the camera lens Which obviously, some hard to see.

As noted in the information, magnesium fluoride (MgF2) crystal Mohs hardness of 6, is the general hardness, but because of the thickness of the thin film, so it is easy to be worn out. Common coating on the glasses are also very easy to be worn, this also depends on the specific use, such as glasses usually only add water wash detergent behind, we should be much longer than the direct use a cloth to wipe the hold time The watch glass is the same.

Coating the inside of the watch glass will not be worn when glass coating damage, there will be a careful look mottled pattern of cases, while attention is required, watches in the long-term storage under storage, be sure to pay attention to moisture, long time in the humid environment the glass surface will be moldy, but also undermines the coating layer.

For vacuum coating machine, the vacuum pump their access to essential part of every manufacturer of a coating machines are manufactured with one or more pumps.

First, the choice of the vacuum pump vacuum pump vibration when you first need to pay attention to when the work produced on the process and the existence of environmental impact, if the process is affected, or alternatively, anti-vibration measures should be taken to a vacuum pump. Choose the time you need to know to be pumping gas composition, selective evacuation if needed, may be insufficient to meet the requirements of a pump, the pump must be combined with a variety of different work with each other, if coater coating requires no oil will have to use no pump.

Second, the coating machine for extreme requirements and working pressure requirements of the greater degree of vacuum, the vacuum pump for higher capacity requirements, a minimum degree of vacuum pump ultimate vacuum equipment than half the number of working vacuum level and above.

Third, each pump has a certain working pressure range, such as diffusion pump pressure of 3 ~ 10-7mmHg, its stable working pressure range of 5 * 10-4 ~ 5 * 10-6mmHg, then not allow the use of a diffusion pump in addition to its work undecided working pressure range.

Higher four, when the gas pressure of the pump is not high demand or high degree of vacuum is not required, the priority selection in a single stage pump, through the exhaust gas pressure or vacuum requirements, single pump often can not meet the requirements, the choice of two pumps or multi-stage pumps.

Fifth, one of the key pump price and maintenance costs also need to be considered.

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.
