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.

Manufacturing method of vacuum coating equipment glass lens

           
1, the previous method: to melt and good optical glass having a diameter of lens diameter to be machined slightly larger in the molding process of the glass rod, and then cut according to the thickness of the lens sheet. Get the specialized machining equipment, according to the requirements of processing into finished products. Machining process mainly: coarse, medium grinding, fine grinding, grinding, polishing, annealing. Coarse to fine grinding of materials are mainly various grit silicon carbide. Polishing method, in the case of less demanding, can be polished by a flame. Advanced lenses must mechanically polishing material is generally cerium oxide.

2, the present method is the first molding die pressing. Mainly in order to reduce waste caused by the original method of processing and improve work efficiency. Methods are: to determine the quality of molten glass good quality according to the lens, to a certain temperature, the viscous state of the glass in a mold, press-molding, the final annealing.

The results in two ways: First, once in place, molded products can achieve the dimensional accuracy requirements. Minimal defects can be compensated by the coating. The mold is very high, as far as I know is not currently available. This product can meet most needs. Accuracy is mainly affected by the lens mold precision. Second is the high precision moldings blank, and then press the above original machining methods, but the processing small amounts, can significantly improve production efficiency. Demanding precision products use this method. Lens is mainly affected by the machining precision instrument precision.

Glass coating machine and its evaporation source

 
 Glass coating machine is mainly used for the production of coated glass after glass coating process to achieve no ordinary glass original features, better performance relative to the original glass, the price may be expensive. The main mode of production of coated glass currently have several: First, vacuum evaporation coating; the second is a vacuum magnetron sputtering; the third is the solution gel method; Fourth powder thermal spraying.
 Glass vacuum evaporation coating machine, it can be used a lot of glass processing products, such as automotive glass, computer screen, mobile phone screens and other glass modules. The principle is the use of a vacuum glass coating machine production coated glass, according to its use of different energy sources evaporation coating system materials are different.
Evaporation plated common evaporation sources:
  A resistance heating type evaporation source having a simple, economical, reliable, widely used in the vacuum chamber of the heating resistor material is melted or vaporized coating, through a series of processes so that the coating material molecules deposited on the glass to thereby obtain high adhesion smooth film, the evaporation source has the following characteristics: a high melting point; chemical stability; low vapor pressure and so on.
  Second, the ratio of the electron gun heating resistance heating evaporation source having a higher energy density, resistance heating can evaporate many materials can not be evaporated, and a higher rate of evaporation can be obtained, but the evaporation source with respect to the resistance structure is more complex and more expensive than expensive.
 A crystal glass for glass coaters, the cathodic arc evaporation source, with a bias power supply or use of the ion source, can provide a higher carrying capacity and lower production costs, made gold-plated titanium nitride, wear membrane, colorful oxidation titanium, super dura mater, decorative metal film, black titanium carbide, diamond film.
