The cause and solution of water-like wood paint coating.

With the development of water-like wood paint in recent years, there have been a variety of ills and problems in the application, greatly affecting the popularization of water-like wood paint, in which the problem of solid wood is an unavoidable problem in the promotion and application of water-like wood paint. Below, the small editor to explain to you, about the water-like wood paint coating reasons and solutions.
What is the phenomenon of wood gluten
Because the wood contains water, in the coating of water-like wood paint, the water of the paint film will penetrate from the surface of the wood, thereby destroying the original moisture balance of the wood, so that the wood surface of the catheter and some wood thorns swell up, destroy the original flat wood surface, the phenomenon of .
Common causes of wood ribs
different wood, due to the natural environment of growth, wood material density is different, wood moisture content is not the same, the serious situation of ribs is very different. Cork ribs are more serious, hardwood ribs are slight, the existing wood roughly divided into cork and hardwood two kinds, for different wood materials, can use two different ideas.
Cork rib analysis and anti-rise rib method
pine, fir and other cork wood material is softer, wood is more loose, cork is the wood moisture absorption, resulting in the entire wood size and volume changes. Because the cork is easy to lead to wood bulging deformation, it is difficult to improve the repair through the follow-up process, can be used to improve the viscosity of the primer, less water or no water, as far as possible to reduce the first primer on the wood's rise.
Hardwood rib analysis and anti-rise rib method
hardwood texture is more hard than cork, wood moisture rise phenomenon is not obvious, spraying water-based wood paint when the general encounter of the phenomenon of ribs, mainly to solve the problem of wood burr. For hard wood, by sealing the role of primers, so that the hardwood surface coarse fibers or wood ribs like needles rise and fix, by grinding to remove, so as to avoid the effects of ribs.
process improvement
in the water-like wood paint coating process, the use of suitable construction methods, but also to a certain extent to reduce the situation of wood ribs. When doing the closure effect, you can appropriately increase the amount of primer spray, if there is a condition of ribs, grinding hard, the surface polished flat after re-painting. When doing the opening effect, first seal the substrate with a solidified primer, then polish the surface wood to remove, and then spray the primer and finish.
