Description
Technical field
The present invention relates to a kind of square silica crucible quality detecting method, more particularly to a kind of silica crucible
The fault detection method of green compact.
Background technology
Silica crucible is the container for producing polycrystalline silicon ingot casting, is that polycrystalline is removed in polysilicon production process
The maximum running stores of the outer consumption of silicon raw material.Its production technology difficulty is big, material purity requires high, made
It is harsh with environment, disposable at a high temperature of 1550 DEG C continuously to work more than 50 hours, be polysilicon
Irreplaceable crucial consumable material in production process.In addition, in face of high-purity polycrystalline silicon raw material for not
The situation that should be asked, the melting that many countries have all carried out polycrystalline silicon raw material according to polycrystalline silicon ingot casting principle is carried
Pure work, silica crucible has also played the effect of no less important wherein.Therefore, it is with polysilicon light
Volt industry has the inseparable, relation of interdependence.As the production Technology of silica crucible,
It is general to have injection forming and two kinds of solidification forming of note.Slip-casting shaping process is the traditional forming technique of quartz,
I.e. the high-performance quartz ceramic mud modulated, injection forming obtains product, state granddad in plaster mold
Department typically uses the technique.Casting molding technique be added in quartz-ceramics mud a kind of organic monomer,
Directly solidification obtains product after being molded in non-punch die.Two kinds of technologies respectively have feature, injection forming production
Product density is slightly higher, wearability is good, is adapted to roll, the square solid product of manufacture simple shape, note
Solidification forming product gas porosity is slightly higher, thermal shock resistance more preferable, is adapted to the complex-shaped thin wall shape of manufacture empty
Core product.Square silica crucible is to need to bear 1400 DEG C -1550 DEG C of height in polysilicon melting process
The pressure of temperature and polysilicon solution, therefore have higher requirement to the heat endurance and intensity of crucible.
Square silica crucible generally has an individual green compact inspection process after green compact drying, main purpose be
Segmental defect is timely found under green state, and makes qualified accordingly, repairs and scraps judgement,
Avoid defective crucible from flowing into the processes such as follow-up sintering, cause the waste of resources costs.Due to square
Silica crucible green compact quality is loose, it is impossible to individually detect crackle using strong light.In the inspection party of crackle
In method, row developer commonly used in the trade is Isoparl isoparaffins, while coordinating 500~1000 watts of iodine
It is longer to find to take in crackle, operation that tungsten lamp irradiates crucible Examination region, and strong illumination is to making
The eye health of industry person is also adversely affected.
The content of the invention
, can be general it is an object of the invention to provide a kind of fault detection method of silica crucible green compact
Under the conditions of logical lamp shines, crackle can be accurately found, it is simple and quick, it is more efficient.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of fault detection method of silica crucible green compact, comprises the following steps：
(1) take dried square silica crucible green compact standby；
(2) open defect is detected：The dried square silica crucible green compact of step (1) are placed on inspection
On platform, under the conditions of ordinary lamps photograph, square shaped silica crucible green compact carry out polishing finishing, are blown with air gun
Dirt is clean, checks whether square silica crucible green compact surfaces externally and internally has open defect with visual means；
(3) fault of construction is detected：By carbon dust solution according to 1:10-20 part by weight is obtained after being mixed with pure water
Crack detection liquid, is uniformly brushed crack detection liquid on square silica crucible green compact by hairbrush
Surface, is spontaneously dried after 20-60s, using the inner surface brush of the clean square silica crucible green compact of hairbrush
One time, if occurring the crackle shape pattern of black on the inner surface of square silica crucible green compact, show
There is crackle, it is on the contrary then in the absence of crackle.
The fault detection method of the present invention, the open defect of the first square shaped silica crucible green compact of energy is examined
Survey, then fault of construction can also be detected, detection efficiency is high.The core inventive of the present invention
Point is to use specific crack detection liquid, just can quick and precisely detected under ordinary light conditions
Go out crackle.During detection, crack detection liquid is uniformly brushed in square silica crucible green compact with hairbrush first
On inner surface, spontaneously dry and wait square silica crucible green compact to absorb after 20-60s, using this side
Case, if there is crackle, crack detection liquid energy is infiltrated through in crackle rapidly, and in the absence of the ground of crackle
The composition of square crack detection liquid is simply to be attached to surface, after drying, using clean hairbrush brush
One time, can there will be no the surface of crackle attachment be mainly carbon dust simply brush recovery crucible it is white
Color table face, and there is the region of crackle, because the carbon dust in crack detection liquid is penetrated into crackle, therefore
Will not be brushed, it is swiped through after obvious aterrimus crackle shape figure can be presented relative to the white portion on periphery
Case, testing staff only need to be simple and quick in normal light according to first just can accurately differentiate, more efficient.
Preferably, the moisture content of the dried square silica crucible green compact of step (1) is not higher than 0.1%.
The moisture content of square silica crucible green compact is controlled to be not higher than 0.1% very crucial, such crack detection liquid energy
Rapid infiltration, crack detection of being faster more convenient for improves detection efficiency.
Preferably, carbon dust solution is by ultra-high purity carbon dust, quartz sand slurry and pure water described in step (3)
According to 1:10~20:15~35 weight ratio is mixed.Control carbon dust solution matches somebody with somebody when crack detection
The proportioning of liquid is extremely crucial, and the rapid Liquid penetrant testing crackle of ultra-high purity carbon dust energy, colour developing is obvious, yes
Testing staff can accurately have found crackle.Quartz sand slurry has homogeneity effect with silica crucible, beneficial to super
The infiltration attachment of high-purity carbon dust, and carbon dust solution viscosity can be adjusted, implement beneficial to detection.
Preferably, the granularity D10 of the quartz sand slurry is 1.0-3.5 μm, D50 is 8.0-12.0 μm,
D90 is 18.0-30.0 μm；The density of quartz sand slurry is 1.5-2.0g/ml；The viscosity of quartz sand slurry
For 50-150cps.Quartz sand slurry parameter is controlled, is more convenient for detecting crackle.
Preferably, the purity of the ultra-high purity carbon dust is 99.9999%.Ultra-high purity carbon powder particle size
In 800-1000 mesh.
Preferably, the ordinary lamps described in step (2) are according to condition：The LED that 18 watts of power.
Preferably, the air pressure of step (2) air gun drifting dust is 0.3~0.6Mpa.
Preferably, step (2) described open defect includes stomata, color spot, foreign matter.
The beneficial effects of the invention are as follows：
1st, fault detection method of the invention, the open defect of the first square shaped silica crucible green compact of energy is carried out
Detection, then can also be detected to fault of construction, and detection efficiency is high.
2nd, the present invention crack detection liquid used in crack detection, just can be accurate under ordinary light conditions
Crackle really is detected, compared to conventional isoparaffin effect more preferably, Check-Out Time is short, efficiency high, has
Effect improves yield, reduces production cost.
