The benefits of glass coating

The benefits of glass coating

Sunlight control coated glass is the most main is to shade insulation, according to its physical properties, also called a glass of hot reflex plated film by magnetron sputtering on normal transparent glass vacuum coating machine on the plating layer or multilayer film, here we referred to as the reflective glass.
Reflective glass, compared to the normal transparent glass on the reflection performance of solar energy, reflective glass, for the first time is 4.3 times higher than common glass, the reflection of the second reflection is 3.1 times higher, 3.6 times higher than that of total reflection on the; On shading coefficient, reflective glass than ordinary glass is 0.18, the coefficient is less, shading effect will be better, greatly reduce the solar radiation and heat transmission; In visible on the reflection and transmission of reflective glass reflecting increased by 20% ~ 20% than common glass, transmission decreased by 55% ~ 55%, and has a good shading performance; On the heat transfer coefficient, reflection than ordinary glass reduced 0.4 W (m2. K), has good heat insulation performance.
Use its good shading and heat insulation performance, can greatly reduce spending on indoor cooling and heat preservation, is a very good energy saving products, and can be through the different metal or metal compounds as target material, to produce different colors of reflective film plating, common color is dark brown, gray, golden brown, tan, brown yellow, coral, through different supplement, achieve illuminative effect, namely beautiful and saving energy.

Vacuum coating equipment glass lens coating knowledge

Vacuum coating equipment glass lens coating knowledge

Basic knowledge of vacuum coating equipment glass lens coating, you know, there are no objects on the light reflection, this is the reason that we can see things. For the lens, in order to be able to make the light through the lens completely, in the film fully reflect the true nature of the situation, the best shot is through a variety of light completely. High-quality optical glass, which can reach 90% light transmittance

Above, the remaining light loss on the need of the lens surface coated film to compensate. Therefore, in the optical lens mainly antireflection coating plated also called AR coating. In order to meet various requirements, often require coated multilayer film. In order to improve scratch resistance of glass, the outermost layer tend to be high-hardness film. In the laboratory, modern technology can reach almost one hundred percent of light through. This is so because in actual use will be more or less affected by dust, dirt, etc. on the lens, making the reduction of light through the lens. Film in many ways, but also so several conventional methods.

High efficiency and energy saving LOW - E coated glass production line

High efficiency and energy saving LOW - E coated glass production line

Low-e coated glass production line production of glass can not only heat insulation, and can block 70% of the infrared. Company technical personnel to open two different glass at the bottom of the infrared lamp. After a few minutes, the face of it there is not much difference between the two pieces of glass, its performance is very different: induction with the hand, common glass has been gradually hot hot, and the LOW - E glass next to it is always cold.
Low radiation (low-e) glass is vacuum sputtering, glass coating on the surface of multilayer coating made of different materials, including silver plating layer of high infrared optical reflection function, namely high block, silver coating under the bottom of the coating for tin oxide (SnO2) antireflective coating, to increase the light transmittance, silver coating deposition of nickel and chromium on the gold (NiCr) metal coating, to protect the function of silver plating, the top coating for tin oxide (SnO2) antireflective coating, main purpose is to protect the overall coating layer, to pay attention to by modern architecture glass high light transmittance, Low reflective rate, high block.

The importance of coating equipment for coating thickness distribution

The importance of coating equipment for coating thickness distribution
     
Vacuum coating electromechanical always want more evenly distributed coating equipment plating thickness on the workpiece, the better the deposition. When the total amount of metal deposited on the workpiece is the same, if the thickness is uneven, it will bring a lot of disadvantages:
(1) For the anodic coating, vacuum coating equipment can not stand at the expense of a thin ...coating of corrosion will first make the matrix rust. And a part of Corroded parts already failed, resulting in a waste of the coating is too thick at the metal. If it is to ensure the thinnest not rust, can only increase the average thickness, resulting in plating cost increases.

(2) to the cathode of the coating, vacuum coating equipment thin coatings at high porosity (see Part 10), it is easy to produce rust spots, and then increase the rust to form contiguous corrosion. Compared with the anodic coatings, cathodic corrosion coating thin place faster. For local seepage nitrogen, carburizing coating, easy to form thin at the hole, lose protection. If the thickness uniformity of the various parts of the porosity is not very different, the overall increase corrosion resistance. For example, the battery bright nickel plated steel rollers, housing (particularly by bottom place) coating is thin, even when washing and drying already starting small rust spots, yellowing, this should "the white" treatment, after rapid drying of water-soluble blocking agent.
(3) For the bright plating, vacuum coating equipment thin coating at the cathode current density due to small, so light leveling poor, affect the overall appearance.
(4) alloy electrodeposition, alloy composition is not the same at different thickness, or the appearance of uneven (such as imitation gold plating), and corrosion resistance are inconsistent or (such as zinc-nickel alloy).
(5) physical coating at different thicknesses, the mechanical properties (such as brittleness, internal stress, etc.) are not the same. If you would have to be plated after stamping molding machine processing, the coating is too thick at the often poor machining performance (peel, crack, powder off, etc.).
Terms of corrosion resistance, or appearance, machining performance perspective, both want to improve the uniformity of the coating thickness of vacuum coating equipment. For the size of the hard chrome plating, if the user requires no plating after grinding treatment, it is difficult to do; sometimes in order to ensure the thinnest reach the final size requirements, thickness uniformity is poor, have greatly increased the average thickness, which is in production are not uncommon. To make each part of the coating thickness on the workpiece as close as possible, we must understand the impact of thickness uniformity factor.
