Abstract
The invention discloses a kind of method measuring electronic ceramics product binder removal effect, it comprises the steps: step 1, standard electronic ceramic product sample and tested electronic ceramics product is carried out binder removal；Step 2, detection sample and the standard electronic ceramic product sample of the tested electronic ceramics product after binder removal are separated crushed into powder；Step 3, two kinds of powder described in step 2 are carried out phosphorus content test respectively；Step 4, by described in step 3 two kinds of pulvurent carbonaceous amounts detection Data Comparisons, when the phosphorus content of tested electronic ceramics Product checking sample is equal to standard electronic ceramic product sample phosphorus content, and the most tested electronic ceramics product binder removal is qualified；Solve that prior art uses that visual method exists when in electronic ceramics product content of organics be difficult to be detected time less, big thus cause problems such as follow-up sintering circuit make a very bad impression by artificial range estimation detection error.
Description
Technical field
The invention belongs to electronic ceramics product binder removal determination techniques, particularly relate to a kind of method measuring electronic ceramics product binder removal effect.
Background technology
Electronic ceramics product is typically made up of metal-oxide, compressing for block materials in order to these metal-oxides can well be bondd, it usually needs add the organic materials such as adhesive, dispersant, defoamer and lubricant in compound；Obtaining sintered density height to realize sintering process, porosity is low, microstructure is uniform, the electronic ceramics product of excellent performance, it is necessary to by base substrate through K cryogenic treatment, makes these organic materials fully decompose, and discharges base substrate, i.e. binder removal process；If being not excluded for these organic materials, if directly being sintered by electronic ceramics product, in sintering process, these Hydrocarbon of cold stage understand carbonization because decomposing without the sufficient time；These carbides of hot stage will be oxidized to gas, make product " bubble " or closed pore increases, thus make product electric property deteriorate or cause and scrap.So, it is very important Quality Control Links that the Organic substance of product the most fully decomposes eliminating；In actual production, typically whether by opening product, to observe section color consistent, if present that local becomes Lycoperdon polymorphum Vitt, sallow or color is inconsistent, then can conclude that non-emptying；But when residual volume is less time, become relatively difficult by the method detection binder removal effect of range estimation, accordingly, it would be desirable to a kind of simple assay method detects whether Organic substance in electronic ceramics product is got rid of totally, thus avoid follow-up sintering circuit is made a very bad impression.
Summary of the invention
The technical problem to be solved in the present invention: a kind of method measuring electronic ceramics product binder removal effect is provided, with solve that prior art uses that visual method exists when in electronic ceramics product content of organics be difficult to be detected time less, big thus cause problems such as follow-up sintering circuit make a very bad impression by artificial range estimation detection error.
Technical solution of the present invention:
A kind of method measuring electronic ceramics product binder removal effect, it comprises the steps:
Step 1, standard electronic ceramic product sample and tested electronic ceramics product carrying out binder removal, described standard electronic ceramic product sample refers to the electronic ceramics product without organic material；
Step 2, detection sample and the standard electronic ceramic product sample of the tested electronic ceramics product after binder removal are separated crushed into powder；
Step 3, two kinds of powder described in step 2 are carried out phosphorus content test respectively；
Step 4, by described in step 3 two kinds of pulvurent carbonaceous amounts detection Data Comparisons, when the phosphorus content of tested electronic ceramics Product checking sample is equal to standard electronic ceramic product sample phosphorus content, and the most tested electronic ceramics product binder removal is qualified.
Crushed into powder described in step 2, its diameier is not more than 100 mesh.
The instrument that phosphorus content test described in step 3 uses is infrared to determine carbon tester.
Beneficial effects of the present invention:
Standard electronic ceramic product sample is carried out binder removal together with tested electronic ceramics product by the present invention, phosphorus content test is carried out respectively after binder removal, by the phosphorus content between contrast standard product and tested product, when the phosphorus content of tested product is less than or equal to standard substance, then can record tested electronic ceramics product binder removal respond well, the inventive method need not manually estimate and carries out, by detecting instrument automatic decision, simple and reliable, infrared determine carbon tester by using and test electronic ceramics product phosphorus content so that it is determined that binder removal degree and residual carbon content, effectively distinguish the organic electron ceramic material of non-emptying, block the material electric property brought due to binder removal residual organic matter to deteriorate, material produces the problems such as pore；Solve use that visual method exists when in electronic ceramics product content of organics be difficult to be detected time less, big thus cause problems such as follow-up sintering circuit make a very bad impression by artificial range estimation detection error.
Detailed description of the invention:
A kind of method measuring electronic ceramics product binder removal effect, it comprises the steps:
Step 1, standard electronic ceramic product sample and tested electronic ceramics product are carried out binder removal；After tested electronic ceramics product is compressing for block materials, first block materials being carried out binder removal process, binder removal is typically completed by cryogenic tunnel electric furnace,
Simultaneously by the standard electronic ceramic product sample without organic material together with tested electronic ceramics product with fire grate glue after in case contrast use, although standard electronic ceramic product sample does not contains Organic substance, but still standard electronic ceramic product sample is carried out binder removal together with tested electronic ceramics product, purpose is the temperature as making standard electronic ceramic product sample have with tested electronic ceramics product and environment, is caused measurement error to avoid final phosphorus content to measure by environmental effect.
Step 2, detection sample and the standard electronic ceramic product sample of the tested electronic ceramics product after binder removal being separated crushed into powder, its diameier is not more than 100 mesh, and diameter is crossed conference and caused phosphorus content test accuracy to reduce.
Step 3, two kinds of powder described in step 2 are carried out phosphorus content test respectively；The instrument that carbon amounts test uses is infrared to determine carbon tester, and this instrument test phosphorus content is simple to operate, and reliably.
Step 4, by described in step 3 two kinds of pulvurent carbonaceous amounts detection Data Comparisons, when the phosphorus content of tested electronic ceramics Product checking sample is equal to standard electronic ceramic product sample phosphorus content, and the most tested electronic ceramics product binder removal is qualified.
