In the outdoor environment, the stone sculpture landscape is eroded by wind, sun and rain, and the color of the surface is subject to a variety of tests. There are many plastic stone landscapes often fade, fade and so on. Plastic stone color is mainly used in liquid pigments sprayed on the surface of plastic stone to produce a specific color, slightly more than four complex colors are required for color process, color layer thickness can reach 0.1 cm.
How can the outdoor stone landscape be maintained for a long time? Based on many years of plastic stone construction experience, Nanjing Yuantai has summed up a number of construction experience, which can prolong the service life of coloring effect.
First, base treatment, plastics cement surface layer to ensure neatness, do alkali removal process, ensure that the color layer is not empty. In many cases, the reaction between cement mortar and water vapor will seep out alkali, destroy the color layer and affect the overall aesthetics. The basic alkali removal process before coloring can largely avoid this problem and ensure the normal use of color in the later period.
2. Choice of coloring materials, plastic stone coloring materials, iron oxide powder coloring, acrylic pigment coloring, paste coloring, etc., each material has its advantages and disadvantages, but in the outdoor environment, the main consideration is the sun resistance of materials, anti-ultraviolet radiation ability is the key to long-term color layer. Ordinary propylene pigments have poor UV resistance, mainly used in indoor environment, outdoor environment, mainly using high-end propylene pigments with sunproof agent; other two materials have strong sunproof, but also outdoor plastic stone main materials.
Three, plastic stone technology, many people will ask plastic stone technology and color life expectancy? Of course, if you have a general understanding of the domestic stone-plasticizing process, you can analyze the smooth surface of the cement hand-made stone, the surface is light, poor hanging color, poor color retention; cement hand-carved stone, rough surface, more voids, uneven, color hanging on the surface, permeability, color, color The service life is longer.
Fourth, color sealing, many plastic stones do not do a closed treatment, the color layer is equivalent to "streaking", there is no closed layer of treatment, color layer full contact with rain, long-term erosion, color layer or peeling off or more warped skin. Water-based closed surface oil can fully protect the color layer, but also play a waterproof role.
The above four construction experience, our company long-term use, after a return visit to customers, plastic stone color layer service life reached more than 10 years. If you have the chance, you may as well try it.
