1, see the color: There should be bright pearl color and metal refractive effect, such as: gold is similar to the color of oily gold paint, any kind of color liquid wallpaper should have a certain refractive effect, in order to ensure the vivid pattern, some special colors Symphony effect should produce different colors at different angles. For example, if the left side is red, the right side is purple. The poor quality liquid wallpaper has only the dioptric effect and no pearl effect. Even the refraction effect is not, or pearlescent. And the effect of metal is not obvious. At present, there are only a few manufacturers in China who can truly master the core technology of Symphony. 2, smell smell: There must be no irritating odor or oily odor (some liquid wallpapers have a faint scent, but the scent is a later added spice, and has nothing to do with quality). 3, see the liquid: No sedimentation, flocculation, spoilage, etc. occur during storage. 4, see the ingredients: The main ingredients of the product should be environmentally friendly pearl raw materials (such as high-grade lipsticks for women, eye shadow, nail polish, etc., which mainly produce pearlescent raw materials) to ensure the environmental protection of products. 5, see water, alkali Observe and verify the water resistance and alkali resistance of the product.

Liquid type liquid wallpaper is dense and should not be too thin and should not be too thick. 7, see the mold: In the construction mold, the photosensitive film pattern is clear and clear, the elasticity is moderate, the film surface is tight and firm, the screen is evenly distributed, and the film stretches evenly and evenly. After construction, the liquid wallpaper can be formed on the wall immediately and film can be formed in 2 or 3 minutes. The construction should not be runny.
