Description
Technical field
The present invention relates to a kind of test device and method of liquid material drying property, more particularly to a kind of liquid ink,
The test device and method of the dry materials such as coating and adhesive, belong to the application technology of ink, coating and adhesive
Field.
Background technology
The drying of ink, coating either liquid materials such as adhesive refers to the liquid materials such as ink, coating or adhesive
Coated in body surface, it is changed into the physics and chemical change process that solid film is occurred from fluid.Liquid ink, coating or
The liquid materials such as person's adhesive are dryly too fast or defect occurs in the excessively slow surface layer formed after coating that is all easy to cause, are not suitable for
Specific production technology.Therefore, drying property is to evaluate an important finger of the liquid materials performances such as ink, coating and adhesive
Mark.
Drying can be divided into surface drying and do solid work, wherein surface drying refers to surface layer film forming, and it refers to being completely formed solid paint film to do solid work.
But film even if reach do solid work not equal to be completely dried if do not mean that its performance has reached optimum state.Film
To be completely dried the time different because of the chemical composition of film itself and curing mechanism, some films be completely dried time up to a few days it
Long.American Society for Testing Materials (ASTM) has made paint film drying property very thin division, particularly may be divided into dry to touch, does not glue
Dirt is dry, finger pressure is dry, face is done, does something in disregard of obstacles, parches or done solid work, it is dry to recoat, without impression drying etc..
For liquid material surface drying test device and method there are many.
National standard (GB/T 13217.5-2008)《The first dryness method of inspection of liquid ink》, provide apparent viscosity model
The first dryness verifying attachment of liquid ink and method of 0.05~0.25Pas are enclosed, twice, error range exists for this method parallel determination
3mm/30s.It can be seen that the range of viscosities that this method is applicable in material is narrow, and applicability is limited.
National standard (GB/T 1728-1979 (1989))《Paint film, putty membrane drying time measuring method》It defines and blows cotton balls
With two kinds of surface drying time assay methods of fingers-touch method.National standard (GB/T 6753.2-1986)《The small glass of coating surface drying test
Glass ball》Define the assay method that air-dried coating surface drying time is measured with ballotini.These types of test method can not obtain
To more accurate quantized data as a result, and its cannot be to the measurement error range of the result prescribed specific of parallel testing.
Automatic drying tester can carry out the drying property of film accurate test and accurately judge, by high-precision
Degree motor drives stroke bar or gear to be moved on film with extremely slow speed, judges that paint film becomes at any time according to the trace depth
The degree of drying of change.Although such test device and test method precision are good, length of testing speech reaches a few hours, is more suitable for film
The accurate Characterization of doing solid work property.
The test method that testing time is long, testing precision is low can be seriously affected to liquid such as ink, coating or adhesive
State stock product quality is quickly appropriately determined, and is also unfavorable for technological parameter and stablizing for product quality on actual production line and is controlled
System.
