Description
Technical field
The invention belongs to the aqueous woodware paint in wooden bamboo processing field to dry category, and in particular to a kind of aqueous woodware paint is done
Dry equipment and its drying means.
Background technology
As people's living standard improves, environmental consciousness strengthens and various countries' environmental law is to organic volatile in coating system
The strict limitation of content (VOC) so that the excellent water paint of environmental-protecting performance has welcome huge development space.Currently, Waterborne wood
Device paint has more and more been applied to field, its environmental-protecting performance such as wooden toy, furniture, floor and has been substantially better than oiliness woodcare paint,
But some problems and challenge are faced in terms of drying.The drying process of aqueous woodware paint is different from oiliness woodcare paint, oiliness wood
The solvent evaporation rate of device paint is fast, drying time is short, and aqueous woodware paint, using water as decentralized medium, the specific heat capacity of water is up to 4.2
× 103J/ (kg. DEG C), its required heat that volatilizees are more vulnerable to environment temperature especially apparently higher than solvent, whole drying process
It is the influence of humidity change.Also, irrational drying means or drying process are difficult to do solid work after easily causing paint film surface drying,
Or cycle length is done solid work, energy consumption is big, and dry mass is unstable etc..
