Description
Technical field
The present invention relates to product testing technical fields more particularly to a kind of graphite to combine the product to be formed with thin property material
The undesirable characterization processes of recessiveness.
Background technique
Graphite is a kind of important carbon material, has many unique properties, and the fusing point of such as high temperature resistant, graphite is up to 3850
DEG C, even if through superhigh temperature electric arc calcination, the loss very little of weight, thermal expansion coefficient also very little；Good electrical and thermal conductivity, graphite
Electric conductivity it is 100 times higher than general nonmetallic ore, be that 3 are only formed due to carbon atom each in graphite and surrounding carbon atom altogether
Valence link, each carbon atom there remains 1 non-bonding electrons to transmit charge, while its thermal conductivity is more than the metal materials such as steel, iron, lead
Material；Good chemical stability under room temperature, can acidproof, alkaline-resisting and organic solvent-resistant corrosion；And good lubricity and can
Plasticity etc..
Therefore graphite has in industry such as metallurgy, electric appliance and machinery and greatly applies, and furthermore graphite still manufactures pencil, ink
Juice, pitch-dark, ink and the indispensable raw material of diamond, diamond.With the development of modern science and technology, the application of graphite
Field is also constantly being widened, and increasingly important role is played in the development of national economy.For example, graphite can be with Bao Xingcai
Material combines, and is formed and is suitable for the articles of sheet material used in electronic product.However, graphite is with thin property material when combining, two
It is easy to produce bubble between person, the presence of bubble will lead to that product is bad, influence the use of product.Therefore, for how detecting
The bad problem of graphite recessiveness brought by the bubble between the product that thin property material combines, it is necessary to propose further
Solution.
Summary of the invention
The present invention is intended to provide it is a kind of, to overcome the deficiencies in the prior art.
In order to solve the above technical problems, the technical scheme is that
A kind of recessive undesirable characterization processes of product, are used for graphite with thin property material and combine the recessiveness for the product to be formed
Undesirable detection, the characterization processes include the following steps:
S1, product is placed in progress first time de-bubble processing in defoaming machine；
S2, bulge detection is carried out for first time de-bubble treated product；
If S3, having bulge, product is defective products；If product is statically placed under conditions of constant temperature and humidity one section without bulge
After time, bulge detection is carried out again；
If S4, having bulge, product is defective products；If product is placed in defoaming machine and carries out second of de-bubble without bulge
Processing, and bulge detection is carried out again；
If S5, having bulge, product is defective products；If product is that there is no recessive undesirable non-defective units without bulge.
As the improvement of the recessive undesirable characterization processes of product of the invention, in the step S1, the detection limit of product is adopted
With the mode for randomly selecting 200pcs product.
As the improvement of the recessive undesirable characterization processes of product of the invention, the technological parameter of first time de-bubble processing is carried out
Are as follows: pressure: 5-10kg, 35-45 DEG C of temperature, time 8-12min.
As the improvement of the recessive undesirable characterization processes of product of the invention, the technological parameter of first time de-bubble processing is carried out
Are as follows: pressure: 6kg, 40 DEG C of temperature, time 10min.
As the improvement of the recessive undesirable characterization processes of product of the invention, the condition of constant temperature and humidity are as follows: humidity 15-25%
RH, 75-85 DEG C of temperature, time 6-12h.
As the improvement of the recessive undesirable characterization processes of product of the invention, the technological parameter of second of de-bubble processing is carried out
Are as follows: pressure: 5-10kg, 35-45 DEG C of temperature, time 8-12min.
As the improvement of the recessive undesirable characterization processes of product of the invention, the technological parameter of second of de-bubble processing is carried out
Are as follows: pressure: 6kg, 40 DEG C of temperature, time 10min.
Compared with prior art, the beneficial effects of the present invention are: the recessive undesirable characterization processes of product of the invention combine
De-bubble is bubbled the technological means such as detection, constant temperature and humidity standing, is capable of detecting when the product problem bad with the presence or absence of recessiveness, together
When the recessive undesirable characterization processes of product of the invention, additionally it is possible to filter out even if there is a problem of that recessiveness is bad, but pass through
The mode of de-bubble can be converted into the product of non-defective unit, avoid the waste of product.
Specific embodiment
Below in conjunction with specific embodiments, technical scheme in the embodiment of the invention is clearly and completely described,
Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based in the present invention
Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all
Belong to the scope of protection of the invention.
The present invention provides a kind of product recessive undesirable characterization processes, is used for graphite and combines to be formed with thin property material
The undesirable detection of recessiveness of product.The characterization processes include the following steps:
S1, product is placed in progress first time de-bubble processing in defoaming machine.
It is handled by first time de-bubble, it is therefore intended that the bubble that may be present in product is discharged, so that product meets
The primary condition of detection.It can be also filtered out simultaneously even if there is a problem of that recessiveness is bad, but it can by way of de-bubble
It is converted into the product of non-defective unit, avoids the waste of product.
S2, bulge detection is carried out for first time de-bubble treated product.
If S3, having bulge, product is defective products；If product is statically placed under conditions of constant temperature and humidity one section without bulge
After time, bulge detection is carried out again.
Carry out constant temperature and humidity standing purpose be, the stability of testing product, although that is, step S2 carry out bulge inspection
When survey, bubble is not present in possible product, but for certain unstable products, the problem that the recessiveness of bubble is bad is subsequent
It gradually generates, therefore by the standing of constant temperature and humidity, advantageously ensures that the accuracy of subsequent detection result.
If S4, having bulge, product is defective products；If product is placed in defoaming machine and carries out second of de-bubble without bulge
Processing, and bulge detection is carried out again.
In step S4, then show properties of product shakiness if product appearance is recessive bad by the stewing process of constant temperature and humidity
It is fixed, then abandon defective products.After carrying out secondary de-bubble for non-defective unit, detected whether again there are bulge, to carry out postsearch screening.
If S5, having bulge, product is defective products；If without bulge, product be there is no recessive undesirable non-defective unit, should
It abandons.
In addition, it should be noted that, characterization processes of the invention based on product detection limit, use and randomly select
The mode of 200pcs product.In this way, characterization processes of the invention do not consider single product substantially with the presence or absence of recessive bad
The problem of, and it is the bad problem of the recessiveness for considering same batch products.When based on characterization processes of the invention, obtain it is recessive not
Yield then shows that the product of entire batch meets requirement in the range of can receive.
Below with reference to specific embodiment, the technical solution of the recessive undesirable characterization processes of product of the invention is lifted
Example explanation.
