The method is used for measuring performances of the glass during a developing process. The method comprises the following steps of drawing the glass fiber; cutting the glass fiber; putting the glass fiber on a supporting member on a horizontal surface; measuring height of the supporting member from a horizontal surface; measuring the height of upper surfaces of at least three points on the glass fiber; and calculating the sag of the glass fiber according to measured results. With the technical solution provided by the invention, the glass is drawn into the glass fiber to measure the sag thereof. The problems that experimental reference data can not be provided by measuring the sag of the glass because glass shape is irregular and the glass size is small during a research and development process of the plate glass. The method provided by the invention has high result reappearance and has enormous practical value for studying the performances of the glass.
Description
Technical field
The present invention relates to the method for testing of plate glass sag, the especially measuring method of glass fiber sag.
Background technology
In plate glass field, the production of glass substrate develops towards large scale, lightening direction, large scale, lightening
The ability loading, taking out and separate in the sagging casing of transport glass between processing stand by impact of glass substrate, larger
Sag or warpage can lead to fragment rate to improve and the warning of cf making technology, have a strong impact on product yield.Glass sag becomes
Important research topic.
Product glass sizes are regular and larger, and uniformly, sag test easily realizes and repeatability is high for thickness degree；But flat
In the R＆D process of glass sheet, the glass existing defects (as glass has bubble, in irregular shape etc.) founded are it is impossible to manufacture birth
Relatively large sized like that in producing line, surface quality is high, the uniform plate glass of thickness is providing laboratory reference data.Current
Under the overall situation that glass substrate maximizes, lightening direction is developed, a kind of easily method is needed to weigh more different material
The sag of the glass that side and process system are produced.
Content of the invention
The present invention provides a kind of method of measurement glass fiber sag, provides one and hang down in the R＆D process being plate glass
The reference standard of degree test, as the theoretical foundation of research and development.
For achieving the above object, the technical solution used in the present invention is: a kind of measurement glass fiber sag method, including with
Lower step:
A, drawing glass fiber: glass wire drawing machine will be melted out and pull into uniform glass fiber, a diameter of 0.1 ~ 1.1mm；
B, anneal under its annealing point temperature 30min by glass fiber, subsequent furnace cooling；
C, glass fiber is intercepted, length is 800 ~ 1200mm；
D, in the horizontal plane two glass fiber supporting bodies of placement, the height of adjustment supporting body and relative distance, two carryings
Body highly consistent, by glass fiber place on the carrier；
E, the measurement height away from horizontal plane for the supporting body；
The height away from horizontal plane for 1 points of the upper surface on f, measurement glass fiber；
G, the sag according to measurement result calculating glass fiber.
Using technical scheme, by becoming glass fiber to survey its sag glass-pulling, solve plate glass and grind
During sending out, glass shape is irregular and glass size is little, so that cannot measure glass sag to provide asking of laboratory reference data
Topic, the method test result repeatability is high, has huge practical value to glass propertiess research.
Specific embodiment
A kind of method of measurement glass fiber sag, comprises the following steps:
A, drawing glass fiber: glass wire drawing machine will be melted out and pull into uniform glass fiber, a diameter of 0.1 ~ 1.1mm；
B, anneal under its annealing point temperature 30min by glass fiber, subsequent furnace cooling；
C, glass fiber is intercepted, length is 800 ~ 1200mm；
D, in the horizontal plane two glass fiber supporting bodies of placement, the height of adjustment supporting body and relative distance, two carryings
Body highly consistent, by glass fiber place on the carrier；
E, the measurement height away from horizontal plane for the supporting body；
The height away from horizontal plane for 1 points of the upper surface on f, measurement glass fiber；
G, the sag according to measurement result calculating glass fiber.
The diameter of glass fiber is preferably 0.3 ~ 0.7mm.
The length of glass fiber is preferably 1000 ~ 1100mm.
Described horizontal plane adopts marble plane.
The diameter difference of the glass fiber that same batch work measures is not more than 0.2mm, more accurately, the glass that same batch work measures
The diameter difference of glass silk is not more than 0.1mm.
The relative distance of two supporting bodies is 500 ~ 1000mm.
In specific implementation process, wire drawing machine will be used using the glass (glass founded) that melts out of different material sides first
Pull into the glass fiber of even thickness, diameter range controls in 0.1 ~ 1.1mm, preferably 0.3 ~ 0.7mm；All choose even thickness for every group
Glass fiber as experimental subject, its diameter of accurate measurement under the microscope, the intimate phase of glass fiber diameter that different groups are chosen
With error control is within 0.1mm；Glass fiber is intercepted as equal length, length controls in 800 ~ 1200mm, preferably 1000
~1100mm；Glass supporting body, this supporting body adjustable-height and relative distance are placed on marble horizontal plane, according to demand
Adjust height and the width of supporting body, highly will not hang on marble for glass fiber, width control system is in 500 ~ 1000mm；
Glass fiber to be measured is individually positioned on glass supporting body, measuring supporting body height is h；On at different 3 points of test glass fiber
The height h of surface distance marble horizontal plane.Calculate the sag of each point, sag s=h-h using obtained experimental data.
The sag of glass fiber is closely related with the sag of glass, can reflect the sag of glass.Choose different material sides or
The glass fiber that technical process is produced carries out above-mentioned measurement it can be deduced that the sag of every kind of glass fiber, and then compares, for reality
Process of testing provides reference data.
Furthermore it is also possible to finished glass is carried out above-mentioned measurement, draw the sag of its glass fiber, simultaneously using traditional approach
Measurement, in the glass plate sag of same position, is then passed through to compare the sag of glass fiber, can be obtained virgin material side or new technology system
Make the glass sag reference value of glass.
In following table, table 1 is the sag of the finished glass and glass fiber being measured using the method, and table 2 is to be surveyed using the method
The sag of the glass fiber that the different material sides of amount or technical process are made.In measurement process, the relative distance between two supporting bodies is equal
For 540mm.
