Description
Technical field
The present invention relates to a kind of oil mark detection method rapidly and efficiently, particularly a kind of aluminium processing industry oil product that is used for is to production
The assay method of product surface influence degree.
Background technology
Aluminium sheet strip and foil surface quality is an important indicator of wrought aluminium products, to product surface oil mark defects controlling one
It is directly the problem for perplexing manufacturer.Oil mark is easily caused in heat treatment process, is the oil of product surface residual after rolling
Reaction, the materials of generation such as product and annealing furnace air are decomposed, cracking, polymerization and oxide etch are attached on product surface
The yellow aberration of formation（There is the different degrees of oil mark such as light yellow, yellow, yellowish-brown）.
The generation of oil mark is a kind of process of chemical reaction.This reaction has started to from aluminium sheet strip and foil rolling sequence, rolls
Oxidizable material such as unsaturated hydrocarbons in liquefaction, containing corrosive compounds such as element sulphur, chlorine element etc., in rolling deformation heat and roll
During moment processed under the comprehensive function of high pressure, different degrees of oxidation deterioration occurs, and aggregates into the jelly of larger molecular weight.
Macromolecular substances are difficult to volatilize in annealing process, remain in aluminium product surface and incomplete combustion occurs with the atmosphere in annealing furnace
Burn, the material of formation is oil mark.
Oil mark Producing reason be concentrated mainly on it is following some：（1）ROLLING OIL mismatches, as viscosity is too high；（2）High viscosity
Hydraulic oil/gear oil is leaked into ROLLING OIL, is caused the viscosity of oil excessive or is introduced corrosive compound；（3）Work during annealing
Skill is improper, as Control for Kiln Temperature is improper；（4）Coiling tension is excessive, and paper tinsel strip volume end face is uneven, and voidage is too small；（5）Aluminum sheets
Paper tinsel surface band oil is excessive.
More and more extensive with the application of aluminium sheet strip and foil, requirement of the people to its surface quality also improves constantly, and oil mark lacks
It is trapped on any product and is all difficult to tolerate.Therefore, a kind of oil of fast and accurately method to product surface is studied
It is highly important that spot, which is carried out qualitative,.
The content of the invention
It is an object of the invention to provide a kind of fast and efficiently oil mark detection method, this method can be used for analysis aluminium to add
The oil mark of ROLLING OIL and lubricating oil is inclined to during work, so as to provide important evidence to judge oil quality.
The present invention's concretely comprises the following steps：The bottom of annealing box is cleaned with ethanol, treats that ethanol volatilization is complete；Take 4 drops（About
0.125ml）Oil sample drops in annealing box surface, sprawls uniformly；Annealing box is covered with aluminium foil, uniform bundle is three small on aluminium foil
Hole, for being vented（Effect is shown in Fig. 1-a）；Annealing box is put into Muffle furnace, from room temperature to 300-400 DEG C, and is incubated 1h；
Cooled down with furnace temperature, the pollution condition on observation annealing box surface.The oil mark grade of patent according to standard sample of the present invention treats test sample
Product carry out oil mark grade judgement.Oil mark grade is divided into nine grades according to the depth of color, respectively I a, I b, I c, II a, II b, II
C, III a, III b, III c, oil mark grade is as shown in Fig. 1-b.This method is simple to operate, the used time is short, is adapted to the oil mark inspection of all oil products
Survey analysis.
The method advantage of the present invention is：
（1）The present invention is used for the detergency dispersiveness test of aluminium roll oil, beneficial to judgement of the research process to oil quality；
（2）The method of the present invention is simple to operate, and oil product consumption is few, and required labour is also less, and integrated cost is low；
（3）Oil box after present invention test can preserve for a long time, convenient to be compared from the oil mark performance of different oil products.
