Common problem of lacquer of waterborne woodwork: varnish besmear film is not level off, burnish is not even Phenomenon : Wood is filled with putty hole processing, after sealing the bottom, coating brush varnish, coating film flatness is low, luster is not uniform. Cause : Hole putty poor quality, loose, solvent absorption. The wood fiber and pith ray on the wood surface are relatively loose. The large pores on the wood are filled with the putty filler, but the putty itself brings a large number of micro pores. Because be bored with child filler content is high, filler itself also has bibulous amount. When be bored with child fine air void rate is high, coating absorbs water quantity to be too big, bring about coating dry fast, not level off, burnish is uneven. If the use of closed primer closed poor performance, not completely closed the wood surface, there is still part of the varnish is absorbed by the wood surface, resulting in uneven varnish coating and gloss. Improvement: Choose the putty with high compactness, add the sealing primer on the putty surface, select the sealing bottom with good sealing performance, and increase the number of coating paths appropriately.

Phenomenon: Wood coating water - based varnish after the grain fuzzy, grain color and luster differ, failed to retain the original style of wood. cause 1.Transparent putty transparency is poor or scraping too thick, reduce the clarity of wood grain. 2.Water-based paint storage time is too long, pigment precipitation, on the shallow under the deep operation without mixing evenly, coating film thickness is uneven. Improvement: 1.Choose suitable transparent putty, and pay attention to the construction thickness and uniformity; 2.Fully stir the water-based paint before use, uniform.

Phenomenon : Part of the water-based paint film from the primer uplift, which contains gas or liquid, showed uneven distribution. Cause 1.When the water-based paint is applied, the dry water-based paint film is exposed to rain. 2.Apply a water-based paint primer to the wet substrate; 3.Water based paint film is affected by acid - base and heat. Amelioration 1.Considering the gas phase conditions, the water-based paint film is completely dried and then re-constructed. 2.Substrate drying and surface treatment should be strictly implemented 3.Choose to accord with the conditions of use of good chemical resistance and good heat resistance of water paint varieties.

water-based resin | water-based industrial coating (a) water paint common problems Common problems with water-based lacquer wood paint: transparency, Color fullness of shade The complaint that often hears about paint of ability in water is paint of ability in water diapure is poor, cannot show the plump godliness of woodiness. In general, the transparency of water-based paint is determined by the following several factors: 1.The transparency of the polymer itself The best way to determine the transparency of the polymer itself is to apply the polymer to the heated black glass. The glass should be heated just above the minimum film forming temperature of the polymer so that  the polymer to cross-linked normally. In this way, the transparency of the polymer can be evaluated without the influence of other solvents and additives. 2.The use of solvents, additives and polymer mixtures will affect the transparency Silicone additives have been shown to affect the transparency of certain polymers. On the contrary, wax emulsions are beneficial for transparency. Some solvents take a long time to evaporate in the lamine ine. They leave a small gap in the lamine hydroxylamine hydroxylamine when they evaporate, dispersing light and increasing opacity. Other solvents at the beginning of the hydroxylamine hydroxylamine hydroxylamine hydroxylamine has been dried, affect the transparency. However, these solvents will gradually evaporate. In this process, the transparency of the film will increase. In the process of preparing a water-based paint, a thorough evaluation of the solvent should be made to determine which solvent will produce the system with the best overall transparency. A mixture of polymer with other polymer will because of particle size, reflective index, reduce the transparency and the incompatibility between the polymer to reduce the transparency of paint hydroxylamine. 3.A system with a high PH will cause the wood to appear "washed white" To the woodiness that does not dye, can add a few red or yellow to catch makings in the first varnish, restore the red, yellow degree of woodiness itself. For stained wood. The use of substrate wetting agent can improve the color fullness of wood.Choosing the right solvent system for the varnish is the key to determining whether the substrate needs a wetting leveling agent. Diacetone alcohol has some very interesting moistening properties.
