During the use of multicolor paint, a series of problems will occur due to long-term exposure to the air, or impurities mixed in the multicolor paint. These common problems mainly include floating layer of multicolor paint, color penetration of multicolor paint and turbidity of dispersion medium, flocculation and agglomeration of dispersion medium, etc. the following is a detailed introduction to the common problems in the use of Jinan multicolor paint
I. floating layer of multi-color paint. Floating layer of multi-color paint refers to that some particles of multi-color paint float on the surface of protective glue in the finished product barrel, covering the whole liquid surface in the barrel and having a certain thickness. These particles float on the surface of protective glue solution, directly contact with air, resulting in a layer of protective glue film wrapped on the surface of particles gradually thinning due to evaporation, until it is damaged and lost, which seriously affects the coating Material uniformity, construction and film decoration
Two. Multicolor paint and disperse medium turbidity. The disperse medium of the multicolor coating obviously presents the same color as the color particle, or the dispersed medium becomes emulsion opaque liquid. When serious, there are many tiny flakes in the cloudy liquid. The main reason for this phenomenon is that the strength of the gel protecting film on the surface of the color granule is not strong enough, too fragile, and the pigments, fillers and auxiliaries inside the color particles can pass through. The weak protective film penetrates continuously, which makes the dispersing medium gradually take on the color of the color particles, resulting in the phenomenon of turbidity. The main reason for the insufficient strength of the protective film is that the concentration of non solvent in the dispersing medium is not enough
3. The dispersing medium flocculates into blocks and agglomerates to form a cotton flocculent colloid that is not easy to disperse, and all the color particles are wrapped in it. The longer the storage time is, the more serious the problem is in Vietnam. The main reason for this is that the pH of the dispersing phase and the dispersing medium is not appropriate, especially the high alkalinity of the dispersing medium, which causes the polymer compounds in the dispersing medium to gradually agglomerate into large and small agglomerates Some of them are network agglomerates
4. Dull primary luster of color particles. Most thickeners, defoamers and some kinds of pigments of cellulose have the function of extinction. White color particles usually have better luster, while other colors have poor luster. The reason is that white color particles generally use neutral titanium dioxide as pigments and fillers. The performance of titanium dioxide is stable, so the luster is better, while some kinds of pigments have strong alkaline or acid Sex, easy to cause color grain to lose luster
Fulet water-based multi-color paint is a new type of environmental protection paint introduced from foreign countries. It is made of a variety of color particles in a specially treated aqueous solution, and it is an excellent coating material with great potential. The coating has excellent durability, strong adhesion, good ductility, water resistance, mildew resistance and pollution resistance.
The surface of the coating is concave and convex and smooth, and the colors penetrate into each other. It can imitate the natural granite in the color, and even achieve the wonderful effect, which is superior to the natural effect. Although the color pattern comes from the natural granite, it is better than the granite. The color depth is arbitrary, and the pattern size is arbitrary. Through the combination of modern color design and natural stone style, it can create luxurious and dignified decoration effect. It can also expand the design space and improve the expressiveness through different grid design, fully reflecting the personalization.
