Analysis of the reasons for the phenomenon of flow hanging in the construction process of water-wrapped sand coating.

The composition of water-wrapped sand
Water-wrapped sand is a kind of water, additives, pigments, protective glue, sand, film-forming substances, such as a certain proportion of the deployment of imitation stone paint, also known as liquid stone. It combines the advantages of multicolored paint and real stone paint, the use of water-wrapped water colorful points covered with natural sand method, so that it has both colorful paint high simulation, but also natural real stone paint texture, is a novel, high-grade exterior decorative paint.

Water-wrapped sand construction process flow reason analysis
for the water-packed sand construction process of the description of hanging phenomenon analysis, the main reasons are the following aspects:
water-wrapped sand paint building effect map
1 Substation problems: water-packed sand before construction needs to be treated on the substation, requiring the substation flat, clean, no oil, water and other substances, the emergence of pollutants will greatly reduce the adhesion of water-packed sand on the substation, resulting in a hanging phenomenon .
2, dilution problem: construction in order to pursue work efficiency, often on the water bag sand thinning, but too much material will lead to water bag sand stick through the low, spraying process, there will be a state of change, that is, the phenomenon of flow hanging. Usually when the construction, in strict accordance with the product construction instructions for thinning.
3, spray gun air pressure problem: air pressure is too small, water bag sand spewing out the initial speed of the muzzle is small, resulting in the water bag sand is bean grain-like spray, bean grain-like appearance makes the water bag sand and the base surface contact area become smaller, and the water bag sand itself has a smooth, resulting in reduced adhesion, coupled with the weight of the water bag sand itself, easy to hang phenomenon.
4, thickness problem: water bag sand spray is too thick, but also easy to lead to water bag sand gravity and substation adhesion imbalance, the phenomenon of flow hanging, water bag sand construction once can not be sprayed too thick, it is appropriate to use multiple spray.
5, weather problems: water-packed sand construction site temperature is too low, humidity is too large, low water absorption rate of the grass roots, easy to lead to drying speed is too slow, thus the phenomenon of hanging.
