Description
Technical field
The present invention relates to the three glass evacuated coating film production lines of silver medal LOW-E, belong to technical field of vacuum plating.
Background technique
Glass is important construction material, and with the continuous improvement required decorating building, glass is in building trade
In usage amount also constantly increase.However, people are when selecting the glass door and window of building now, in addition to considering its aesthetics with other than
It sees outside feature, more focuses on the problems such as control of its heat, refrigeration cost and internal sunlight project comfortable balance.This allows for plated film glass
Upstart in glass family --- Low-E glass is shown one's talent, and becomes focus concerned by people.
Low-E glass is also known as low emissivity glass, is to plate the film of multiple layer metal or other compounds composition in glass surface
It is product.Its film plating layer has to the characteristic of visible light high transmission and centering far infrared high reflection, make it with simple glass and
Traditional coated glass for building is compared, and has following clear superiority:
(1) excellent hot property
The heat loss of outer door glass is the major part of building energy consumption, accounts for 50% of building energy consumption or more.It is related
Research data shows that the heat transfer of interior surfaces of glass based on radiating, accounts for 58%, it means that subtract from the performance for changing glass
The loss of few thermal energy, most efficient method are to inhibit the radiation of its inner surface.The radiance of common float glass is up to 0.84, when
After plating one layer of low radiation film based on silver, radiance can be down to 0.1 or less.Therefore, it is built with Low-E glass manufacture
Object door and window is built, indoor heat caused by due to radiation can be substantially reduced to outdoor transmitting, reach ideal energy-saving effect.
Another significant benefit brought by the reduction of indoor thermal loss is environmental protection.Cold season, because of constructure heating
The discharge of the pernicious gases such as caused CO2, SO2 is important pollution sources.If using Low-E glass, due to heat loss
It reduces, can be greatly decreased because of fuel consumed by heating, to reduce the discharge of pernicious gas.
(2) good optical property
Low-E glass has high transmittance to visible light in sunlight, and up to 80% or more, and reflectivity is then very low, this
Make it compared with traditional coated glass, optical property is greatly taken on a new look.From outdoor viewing, appearance is more transparent, clear, that is, ensure that
The good daylighting of building in turn avoids light pollution caused by previous large-area glass curtain wall, the reflection of hollow glass door and window light
Phenomenon builds more soft, comfortable luminous environment.
The above-mentioned characteristic of Low-E glass makes it obtain increasingly extensive application in developed country.China is an energy
The relatively deficient country in source, the occupancy volume per person of the energy is very low, and building energy consumption has accounted for 27.5% or so of national total energy consumption.
Therefore, the production technology of Devoting Major Efforts To Developing Low-E glass and its application field is promoted, significant social benefit and economy will be brought
Benefit.
It is as follows to lead two kinds of Low-E glass making processes difference to be used both at home and abroad at present:
(1) online high temperature pyrolysis sedimentation
Online high temperature pyrolysis sedimentation is completed during float glass cooling technique, liquid metals or metal powder
It is directly injected on hot glass surface, with the cooling of glass, metallic diaphragm becomes a part of glass.Gu this, the film layer is hard
It is hard durable." Low-E " glass of this method production has many advantages: it can be with hot bending, tempering, it is not necessary under hollow state
It uses, it can be with long term storage.Its shortcomings that is that thermal property is poor.Unless film layer is very thick, otherwise its " u " value is only sputtered
The half of method " Low-E " coated glass.If it is desired to improve its thermal property by increasing film thickness, then its transparency is just very
Difference.
(2) offline vacuum sputtering
Vacuum coating technology is begun to show in the 1930s, four the fifties start industrial application occur, and industrialization is big to advise
Mould production starts from widely answering in the 1980s, obtaining in the industry such as electronics, aerospace, packaging, decoration, gold stamping printing
With.Vacuum coating technology is the new technology of a kind of novel materials synthesis and processing, is the important set of field of surface engineering technique
At part.Vacuum coating technology is the plated film that the surface of solids is coated to one layer of property using physics, chemical means, to make
There is the surface of solids wear-resistant, high temperature resistant, corrosion-resistant, anti-oxidant, radiation protection, conduction, magnetic conduction, insulation and ornament lamp many to be better than
The superior function of solid material itself reaches and improves product quality, extends life of product, the significant technology warp of energy saving and acquisition
The effect for benefit of helping.Need plated film is referred to as substrate, and the material of plating is referred to as target.
Magnetron sputtering is to make target atom or molecule be sputtered out using lotus energy particle bombardment solid target and deposit to
A kind of technique of substrate surface.Metallic target and ceramic target can be selected in target.Magnetron sputtering the preparation method has deposition rate height, substrate
The advantages of temperature is low, film forming adhesion is good, easy to control, at low cost, suitable large area is film-made.Exactly needs are made for vacuum evaporation
The substance of film, which is put in vacuum, to be evaporated or distils, and is allowed to be precipitated over the substrate surface.The device of vacuum evaporation is simpler
Single, technological parameter is less, the growth of easily-controllable made membrane, and impurity content is low in film.But the height of vacuum degree directly affects film
Structure and performance, vacuum degree is low, and material is seriously polluted by residual gas molecule, film performance be deteriorated, improve underlayer temperature have
Conducive to the desorption of gas molecule.
Off-line process produces Low-E glass, is to generally use vacuum magnetron sputtering coating film technology in the world at present.And Gao Wenre
It is different to solve sedimentation, using in sputtering method production technology, glass horizontal is placed on transfer roller, is sent into 10-1The pa order of magnitude it is true
In Altitude, it is passed through suitable process gas (inert gas Ar or reaction gas O2、N2), and keep vacustat.By target
Ag, Si etc. are embedded in cathode, and are being placed in magnetic field with the horizontal direction of cathode vertical to constitute magnetic control target.It is yin with magnetic control target
Pole, in addition direct current or AC power source, under the action of high voltage, process gas is ionized, and forms plasma.Wherein, electric
Son carries out high-speed screw movement under the collective effect of electric and magnetic fields, and collision gas molecule generates more cations and electricity
Son；Cation hits cathode targets after reaching certain energy, the target material deposition being sputtered out is in glass under the action of electric field
Film is formed on substrate.In order to form uniform film layer, cathode target moves back and forth close to glass surface.In order to obtain multilayer
Film, it is necessary to use multiple cathodes, each cathode is moved back and forth in glass surface, and certain film thickness is formed.Sputtering method work
Skill produces " Low-E " glass, needs one layer of fine silver film as functional membrane.Fine silver film is between two layers of metal oxide film.Metal
Oxidation film provides protection to fine silver film, and increases the purity and luminous transparency of color as the middle layer between film layer.
Currently, the target product of domestic and most import magnetron sputtering film production lines be be coated with simple substance film and
Solar control film glass based on metal film.This kind of product technique is relatively easy, and the requirement to equipment is lower.Therefore, these are given birth to
Producing line is not able to satisfy the requirement for being coated with LOW-E glass.
