As environmental protection coating, waterborne wood paint to achieve a good coating effect and quality, of wood coatings technology have to be very skilled.
So, how to ensure the quality of the wood lacquer coating effect and below small make up to introduce the next: 5 rules ensure the quality of waterborne wood paint renovation.
1, grinding adjustments: the polishing of waterborne wood coatings, it is very important for the whole construction. In terms of transparency putty and transparent primer, good polishing is required. In general, the higher the hardness of waterborne wood coatings, grinding relatively is better; The longer the drying time, polishing sex.
2, drying speed adjustment: waterborne wood coatings, the drying speed is a key factor. Because of drying speed affect the coating efficiency, cannot wait after coating, so the paint drying speed can directly affect the production efficiency, waterborne wood coatings to replace oil paint would have to improve the drying speed.
3, surface modification, because many of those who choose and buy when the judge paint, like to use nails or keys on the paint film two strokes, see if there is a scratch, so waterborne wood coatings must have high hardness and scratch resistance.
to do 2 - one-component waterborne wood paint 3 h hardness is a bit difficult, but also has the very good scratch resistance. General situation, can add some surface additives in waterborne wood coatings, making it in the process of dry film, gradually migrate to the surface, using its own characteristics and high hardness to improve the scratch resistance of paint film.
4, flow and flow hanging in the balance: the final step is to adjust the viscosity of water-based wood coatings, viscosity term is called rheological properties. Waterborne wood paint are good, should not only have good flow property and good resistance to flow to hang.
improve can reduce unnecessary waste flowing property, on the other hand on the handle and gloss of the film will have a larger increase. Will cause sagging and not enough viscosity, viscosity is too high and will affect the flow property, so keep in flow leveling and sag, the balance of commonly used thickener, both neither can affect the water resistance, and improve the viscosity and flow property.
5, improve transparency: the higher the transparency can show the natural grain of lumber, silicon dioxide matting powder determines the transparency and luster adjusted balance.
