Description
Technical field
The present invention relates to field of optical detection, more particularly to a kind of measurement hollow glass entirety transmittance, reflectivity and face
The Split type device and method of color.
Background technology
Existing building glass is mainly hollow glass structure, and based on regular reflection and regular transmission color, extensively
Instrument applied to object color measurement can not measure divided glass at the same time mainly using diffusion measure geometry condition, and endless
The full color measuring for being suitable for building glass.In addition, building glass general size and thickness are larger, general color measurement instrument is difficult
To carry out overall measurement to finished product.
At present, the method mainly for detection of building glass transflector when color is：Hollow glass is disassembled into monolithic
Each monolithic glass, is then cut into the size for meeting instrument requirements by glass, detect respectively each monolithic glass transmittance and
Reflectivity, then pass through the transmittance of theoretical formula method integral hollow glass, reflection when color.
At present, when color will usually use ultraviolet, visible, near infrared spectrometer etc. to detection building glass transflector
Equipment.It is not readily portable since the usual volume of this kind equipment is larger, therefore be mainly used for detecting work in laboratory.Due to instrument
The limitation of structure, and hollow glass finished product general size for building is larger, is difficult to the overall transflection of directly measurement using this quasi-instrument
Penetrate than, it is necessary to disassemble finished product, being measured respectively to each monolithic, then calculate the transmittance of integral hollow glass, reflectivity and
Color.
Wherein, it is the shortcomings that above-mentioned technology：
1. building glass is usually hollow glass structure, general color measurement instrument can only measure monolithic glass, can not be right
Building glass finished product carries out nondestructive measurement, it is necessary to disassembles hollow glass, it is impossible to directly measures the transflector ratio of sample entirety.
2. glass to be cut into the size for meeting instrument requirements, complicate sample preparation procedure.
3. most of building glasses are tempered glass, and tempered glass can not be cut, so large stretch of tempering glass can not be detected
Glass.
4. building glass is typically coated with low-radiation film, exposure easily aoxidizes low-radiation film in atmosphere, therefore disassembles meeting to surveying
Measure result and produce considerable influence.
5. being only suitable for sample detection in laboratory, the Site Detection and checking and accepting of building glass can not be installed.
The reason for further analysis causes disadvantages mentioned above is as follows：
1. the measure geometry condition of general color measurement instrument is diffusion measuring condition, and since glass is mainly that rule is saturating
Penetrate and regular reflection, therefore monolithic glass can only be measured, be not suitable for measurement divided glass.
2. since instrument reflected light path limits, when tested glass sample thickness is larger, it is difficult to it is each to be completely received sample
The reflected light signal on surface, it is impossible to directly measure the reflectivity of hollow glass entirety.
3. since apparatus structure limits, nondestructive measurement can not be carried out to building glass finished product, it is necessary to disassemble hollow glass.
4. since instrument sample storehouse size limits, the glass sample in the range of certain size can only be measured, therefore by glass
The size for meeting instrument requirements is cut into, complicates sample preparation procedure.And tempered glass can not be cut, so can not detect
Large stretch of tempered glass.
5. since the aerial low-radiation film of exposure easily aoxidizes, the low-radiation film after oxidation can produce measurement result
Considerable influence, thus after disassembling measure monolithic glass be obtained by calculation again overall transflector than result may with disassemble before
Finished product is not inconsistent.
6. traditional detection instrument is generally desk-top instrument, limited be subject to volume and weight, be only suitable for testing indoor sample
Detection, can not have been installed the Site Detection and checking and accepting of building glass..
Therefore, it is necessary to provide a kind of new technical solution.
