Description
Technical field
The present invention relates to a kind of liquid coating volume solids contents to measure scraper plate and its application method.
Background technology
Currently, coating is by material compositions such as resin, pigment, filler, solvent, auxiliary agents, wherein solvent formed a film in coating
It constantly volatilizees in journey, is completed when solvent volatilizees, the non-volatile matters such as resin, pigment, filler for leaving are constituted with decoration, protected
The coating of shield effect, to reach protection and the decoration to covering.The protection decorative effect of coating not only with paint composite
And formula is related, also has substantial connection with the thickness of coating.The volume solids content and painting cost also close phase of coating simultaneously
It closes, obtains the coating of same thickness, volume solid content is higher, then the coating consumed is relatively fewer.
Currently, the monitoring method for volume solids content in coating mainly has：
Method one is theoretical calculation：According to the addition of each substance in formula, in conjunction with the volatilization feelings of each substance of addition
Condition sums up the volume after curing of coatings is calculated, and due to being simply to sum it up, does not consider many variations in film forming procedure
Factor, as the infiltration in resin and granules of pigments gap, small molecule volatile matter participate in film formation reaction become nonvolatile matter, resin with it is molten
The swelling etc. of agent, causing theoretical calculation, there are large errors.
Method two is international standard ISO3233《Paint and varnish --- measure coating by measuring dry coating density
Nonvolatile matter volumn concentration》The method of middle use, this method is in the mass percentage and body for measuring coating non-volatile content
Product percent solids use identical condition of cure and can simulate coating decoration condition of cure, can preferably react practical feelings
Condition, credible result degree is higher, the disadvantage is that haveing suffered, experiment process is more complicated, for generally without special training coating material production,
There are certain difficulties by user of service.
Method three is theoretical calculation+mensuration, by detecting the quality solid content of coating and the density of film, is calculated
The volume solids content of coating, this method are related to the density measurement of dry film coating, same convenience not fast enough.
